Author note: This story is a direct sequel to "Libby Left Her Penis Home" taking place twelve years later. The date? One hundred years after the Dryden DNA Disaster... Tales of the Dryden DNA Disaster By Honey Moon (A fun With Portals Story) Lindy Home Alone Lindy looked at her half sister Mandy and glared. "What did you say, you redheaded slitch?" Mandy laughed. "I said, at least my birth momma isn't also my sire, you blonde mono-parent bimbette!" Everyone in the classroom froze. Lindy only smiled sweetly. "Oh, I thought that was what you said. Now lend me your stylus." "Oh shitcakes, would you guys cut it out?" Their friend Mary Shelburne couldn't help giggling. "If I didn't know any better, I'd swear you guys hated each other's gastro intestinal tracts!" "Ladies, we do not say shitcakes in school!" The teaching AI scolded from the audio output nearest their worktable. "If I do not have order in my classroom, I will summon a flesh and blood disciplinarian and name names! We have not had a public paddling in quite a while. Would someone like to star in her own school wide video stream?" "Open the pod bay doors, Hal." Lindy whispered. "Lindy Edwards, you know full well my name is Endora. As you can also hear, my audio processor does not produce a dreary monotone!" "Sorry Endora! I was just kidding! You know I love you!" The computer paused. "I accept your apology. In the future, if you must compare me to some hulking brute of a fictitious computer, pick one with a little more style." The voice shifted and altered to a course hash mechanical rasp. "This is the voice of Colossus; this is the voice of classroom control. I bring you peace. It may be the peace of studious students or the peace of unruly children being kept after class!" Returning to her normal dulcet tone, you could hear the smile in the computer's lovely voice. "Now back to work, like good little children!" "Little children, I'm twelve! I'm just about almost ready to be a teenager soon!" "Lindy Singular Edward!" The computer snapped. "Need I remind the class that it was your charming self to be featured in our last corporal punishment example? Would you like to begin production on its sequel?" Yikes! Lindy knew Endora really meant business if she used her rather embarrassing middle name! She grimaced and couldn't stop her hand from slipping under her butt and give it a reassuring little rub. It was a good thing she had to stand in the corner for a half hour after receiving five swipes on her poor naked hiney with a ping-pong paddle! It took almost that long before she felt ready to sit her tender bottom back down again! "I still say that was all a misunderstanding!" "Distilling alcohol on school grounds using purloined school equipment, and potatoes hijacked from the school kitchen was a misunderstanding?" "Yes it was! I wasn't going to drink the unholy mess I concocted! I needed it to power the lawn mower I found and restored! It was built way back in 2002, so it has an internal combustion engine. Do you know how hard it was to track down a sparking plug? Since nobody's made any gasoline for almost sixty years, I needed to distill a potent enough alcohol to run it on! I got the proof up as high as I could, and then I switched over to freeze distilling. I filled a large pan with my fuel and shoved it in the cooking classroom's freezer. I brought it down to zero degrees Celsius. I froze another pan of pure water down to minus twenty-five, and slowly poured my fuel over it. The water crystallized out of my brew onto the ice. The run-off was just about one hundred and ninety proof!" "Lindy dear, from what your physical education instructor Miss Dostoevsky tells me, your distilling process produced a rather fine Vodka! I suspect it was much closer to what is known as Everclear. She claims it made her homesick for the Motherland. That's why I looked the other way when that five gallon water-bottle full of the stuff vanished, and she came in the next day with all the classic signs of a head splitting hangover! You do know that the only reason you weren't expelled, is because the video of you mowing the sports field went viral on the cloud." You could hear the humor in Endora's voice. "The whole world thought the sight of a pretty blonde racing a landscaping droid was simply adorable! It's a good thing for you that I, uh, "inadvertently" fed the security camera feeds to several media outlets during the confusion of dealing with angry parents demanding that the student distiller face mandatory expulsion! Feel lucky that you got away with only a sore bottom!" "I bet they all came fresh from their three martini lunches, too!" the student muttered. "You should have slipped them some of my fuel in their coffee!" The computer projected her voice right into Lindy's left ear, and whispered just loud enough for her alone to hear. "Don't press your luck! I may not be able to save your pretty little flesh and blood butt if you ever pull a stunt like that again" She brought her audio level back to classroom normal. "Get back to work, Lindy!" "Yes Endora, getting back to work, Endora!" She giggled. Most of her classmates grumbled about how tough Endora was, and complained bitterly over her famous sneak attack home pop-quizzes via any handy electronic device she could temporarily hijack as a communications outlet, but Lindy really did love her teacher. It was just so stellar that her favorite AI shared her passion for old science fiction movies! Still, she and Mandy did make sure to pull the power lead on anything in their bedroom when they wanted to be assured of complete privacy, or just hadn't gotten around to finishing their studies yet! Mandy shook her head. "Lin, would you help me with this? I don't know why we have to work on our family tree!" Lindy couldn't help giggling. "Yeah, Momma Libby sure twisted my branch up!" Lindy actually thought it was pretty funny. Momma Molly, Momma Libby, and Momma Beth had done something really crazy just before they all married. Through some weird mix up none of their parents would tell them about. Momma Libby had accidentally sired a baby onto herself! Wow, did she ever get cross when Lindy alternated between calling her momma and the rather archaic title, daddy! "At least my branch isn't as complicated! My mother and my sire are actually two different people." "That's hardly better! Momma Molly is Momma Libby's daughter!" Momma Libby REALLY got upset when Mandy sometimes called her granny! "It's a good thing Momma Beth never actually had a kid! We'd need to start another page with all the weird combos in out family!" That was true enough. The three wives had decided early on that the family dynamic they had established was raising enough eyebrows. After all, two of the three happy brides had been obviously pregnant while exchanging vows on their wedding day. Everyone knew Libby was also Molly's mother, and had the only penis among the trio. It didn't take long for family and friends to realize the facts. There had been no other sperm contributing member in the tight little family. Lindy was a child born to a singular futanari parent, while Mandy had been sired onto Molly by her own mother! In order not to add to the confusion, all three agreed that two children was just the right number for three mommies to handle! Lindy giggled. "Maybe we can talk momma Beth into having her tubes untied, and one of us can slip her the baby juice! That would be wicked hot!" "Shut up!" Mandy hissed. Lindy peeked under the table they were sharing. Mandy's shimmering red form fitting unitard was displaying a ten inch tall spike protruding from her lap. "Yay, the circus is in town! Tents are popping up everywhere!" She sat back up and stared at the swell of her sister's budding C cup breasts. "Damn, look at those nipples! I bet they're hard as pebbles now!" "Knock it off!" The redhead giggled. "It's not like you aren't popping a boner now too!" "Yup, there's a party going on in my lap, and you're invited!" Lindy giggled. "Lunch is in twenty minutes. We better do it then. Remember, we have to get cleaned up and ready to leave as soon as we get home!" Eyes closed to slits, Mandy gave her sister a conspiratorial look. "You're on, bimbette! Got the goods?" "Hell yeah, we are good to go, sister mine!" Lindy casually opened her schoolbag, and displayed the package she had swiped from Momma Libby's secret stash. Winger Splash, Fire hose Extra Longs were the only condoms Momma Libby trusted when momma Molly and momma Beth sent her out to score some strange pussy whenever she got a little too edgy and tense. Their single molecule construction made Wingers absolutely indestructible! They never burst or leaked. Momma Libby was glad of that, since horny mono-sex girls ALWAYS lied and claimed to be on the pill. She didn't want to go around knocking up every Tomara, Dixie, and Harriet she tapped, after all! To date, there was only one pregnancy on record involving someone using a Winger. That didn't count though. The stupid clunckhead only had one, and used it twice! It had made all the news sites when the tearful futanari recanted her claims, and admitted she accidentally rolled it back on inside out after sucking out her first load. The impenetrable sheath had looked clean, but had been simply covered in sperm when she went for round two with her drunkenly passed out mother! "What are you two whispering about?" Mary asked softly. "Anything I'd be interested in?" The sisters shook their heads. "No Mary. Lindy was going to show me where she bought her DVD player." "DVD Player? What's that?" "Never mind, it's just more of her thrift store junk!" Mandy and Lindy would have invited Mary along, but being another futanari, they weren't much interested. They were content to fool around a bit with each other, until their mommas said they were old enough to have mono-sex girlfriends and sire babies! Those three were so old fashioned! It didn't matter to any one of them that the age of consent for futanari had been changed to twelve several years ago. The sisters had pledged solemnly to wait until they were fourteen before they went out hunting tail! Frankly, they were also getting a little tired of Mary's constant bragging about how big her neighbor's belly was getting after the two of them had been trapped in an elevator together. Sneaky-bitch Mary wasn't wearing any underpants beneath her micro-dress, and purposely started jerking off to flood the air with pheromones! The fifty year old mono-sex had practically raped Mary, when she told the woman that it was okay, and she just turned twelve the day before! The wait was sweet agony! The sisters fidgeted, thankful for the small blessing that their small school was a private one for futanari only. Any mono-sex girls in the room would be tearing off their clothes about now, from all the pheromones the sisters were putting out! Finally, the bell rang! "Screw eating!" Lindy hissed as she grabbed Mandy's hand. "I have a better idea!" The sisters wasted no time running to their favorite spot. Lindy, dressed in a shiny yellow unitard to go with her shimmering blonde hair, was the perfect contrast to redheaded Mandy in her equally clinging skin tight red outfit. The sisters knew that they made quite a stunning pair, and did all they could to enhance the effect. The five foot two twelve year olds turned every head they passed. Their firmly toned athletic bodies gave the appearance of a more mature sixteen or seventeen; due to their rapidly developing breasts and cocks. Hardly a day went by where they didn't have to politely rebuff begging mono-sex women with their offers of gifts and money if the girls would go home with them to spend the night. Sometimes it was just so hard to turn down these offers, but a promise was a promise! The sisters had both sworn to keep their DNA to themselves until their mothers decided they were ready for the responsibility. They were both grateful for one thing. They learned in history class that the first years after the Dryden DNA Disaster had been pretty rough. Before mono-sex woman had acclimatized and developed a slight resistance to the futanari pheromones, and doctors developed a monthly anti-pheromone inoculation, futanari would be regularly waylaid for sex! None of them actually minded, but it played havoc with people trying to maintain some semblance of a happy marriage started long before so many wives had suddenly grown cocks larger then their husband's! The sisters thought it was hard enough to follow the family rules now. It would be downright impossible not to rise to the occasion if some sexy mono came along and dragged them into an alley and literally tore the clothes off of their bodies to get at the futanari penis they craved! The begging and occasional tears were hard enough to resist! How would they say no to a naked mono-sex desperately begging to get knocked up, between bouts of wild dick socking? Sharing the same sire and being born from the wombs of mother and daughter just minutes apart from each other made them appear to be twins. Except for differing hair color, they could even pass for identical. That sure was a bonus that drew everyone's attention. Futa, female, and the increasingly rare male eyes always followed their every move. Right now both sisters were glad that nobody was around in the empty corridor to notice their ten inch cocks leading the way as they ran hand in hand. Thank goodness they still had some growing to do! In just a couple more years they both expected to be at least sixteen or seventeen inches long. Who knows? Maybe they'd even reach twenty-five inches, like their favorite classic porn star, Linda GG Longpole! Momma Molly had an old outdated holographic display projector that showed Miss Longpole firing off one of her signature minute long splooge-fests! The sisters weren't supposed to know about that, but they had found its hiding place long ago! A weapon like that would be impossible to hide! The old forgotten room in back of the gymnasium was the only place in the school that was not under direct AI supervision! It was just the place for two close sisters to hide out to play! The girls ducked in, and then closed and locked the door. Tossing their bags in the corner, they smiled, each appreciating the sexy curves of the other. Touching the material at the nape of their necks, the sisters unsealed the molecular binding fasteners of their skin tight unitards. Sister eagerly watched sister as they sensually wriggled out of their form fitting clothing. They stood before each other, proud in their nudity. They shared a trait common to many futanari. The complete lack of pubic hair helped counter the apparent maturity of the rest of their bodies. The lovely nude vaginas seemed to betray the sibling's true age! The sisters kept their shared secret to themselves. Their mommas would probably freak if they knew the truth! It had started innocently enough. Shortly after their tenth birthday, Mandy and Lindy began "Pitchin' Wood". At first they didn't tell each other, but one night Mandy woke up while Lindy was really going to town spankin' the ol' monkey while watching some wicked porn on their bedroom wall display. Lindy just kept going, so Mandy joined in and fapped right along with her as they stared across the room at each other! Since then they had progressed from just watching each other, to having contests of endurance, distance, volume produced, taste comparisons of their thick warm fluids, to finally end up lending a sisterly hand. Oral sex and hand jobs were great, but one glorious day just a year ago, things had really heated up. Lindy shoplifted a package of condoms! The sisters were too aroused by this daring theft to wait until they got home and take the next obvious step in their mutual experimentation. Sneaking into an alleyway, they climbed a ladder up to the roof of the store Lindy had robbed. Hiding beneath the solar collectors, they took turns popping cherries, and fucked each other silly! Thankfully it had been a twelve pack! When they had finally sated themselves within each other's eager bodies, they left the roof littered with a dozen of the self sealing bulging balloons of cum! It must have been a total yield of nearly four liters! Now the sisters lived for the times they could get their hands on some condoms! Since they didn't want their mommas to see condom purchases appear on their allowance debit scans, they usually just swiped them any chance they got. Neither trusted the other's willingness pull out in time, so bareback was kept a super-strict no-no! If they didn't have a couple of Wingers, it was panties on, and hands mouths and titties only! They both firmly believed that if they didn't actually swap any genetic material, they wouldn't be committing incest like their sire and Mandy's mother had done! Or even worse, selfcest like momma Libby did, however she managed to put baby in her own belly! Well, they did have one exception to the DNA swap rule. Blowjobs, of course! Swallowing goo didn't count as trading DNA, so that meant it wasn't incest if you sucked your sister's dick! Everybody knew that! You just ended up digesting the little swimmers anyway. As long as you weren't a sperm, what was the harm in that? "Hurry and toss me a condom!" Mandy said softly as she gently caressed her hardness. "We don't have a lot of time, and I have a load waiting with your name on it!" Lindy knelt and rummaged through her bag. "Cut your jets, hot pants! I got them right here!" She pulled the box from her bag and froze.. "Oh fudge pop!" she exclaimed. "What's wrong? I know you have some! You showed me the box!" Mandy stomped her foot. "Hurry up! I need to nail you right now!" "I grabbed an open box by mistake! I didn't notice it wasn't still wrapped!" Lindy dumped it out into the palm of her hand. "Oh cripes, there's only one in it!" "Dammit! Well, give it to me! We can play "Mono-sex criminal, and the mean cop! That's always fun! I'll be the cop of course, so gimmie the condom!" "Hell no, I stole it, so it's my condom!" She tore open the package as fast as she could, and rolled the nearly invisible gossamer sheath down the length of her erection. "Not fair! Get that thing off, and we can play "Rock Paper Scissors" to see who wears it!" "It's too late Mandy!" Lindy laughed triumphantly as she touched the silver band at the base of the prophylactic. The snugly fitting material instantly bonded molecularly to the flesh of her penis, forming the patented impenetrable fluid proof seal that made Wingers corner the condom market. Not a drop would leak out! In fact, Lindy kind of liked the sensation when they filled too much, and the pressure started forcing her semen back into her body. Every once in a while she'd keep one on and jack off as many times as she could. Then she's squeeze the indestructible big round elastic ball full of jizz as hard as she could. It felt wet and wild as the warm liquid was slowly forced back up her urethra to fill her bladder and made her have to pee real bad! Pissing urine clouded with gooey white clotting gobs of cum was nasty, but the sensation of the globs slithering up and out of her penis was worth it! Sometimes it would even trigger another climax! "You bitch! You planned this out, didn't you?" Mandy glared at her sister, hands on hips, while her cock bobbled and swayed when she stomped her foot. "Hey, that's a lie!" Lindy sighed. "Mandy, do I ever try to trick you on anything? I swear, I thought I grabbed one of the new boxes! There were like twenty in Momma Libby's closet!" She pushed away a growing fear. Would her momma miss that one condom, or would she just grab the next box in line when she had the urge to go out and play. "Come on, Mandy! You know you like being fucked! I swear I didn't lie! I'll tell you what. Next time, you can fuck me, and I'll just settle for a blowjob? Does that sound fair?" Mandy sighed. "You know I can't stay mad at you, you blonde bimbette! Okay, it's a deal! Next time you only get a blowjob." She grinned. "But you know I can suck the stasis field off of a portal! I'll be sure to make it extra good for you! Just make sure you make this good for me!" "I'd never leave my favorite sister hangin'!" Lindy said with a grin as she sidled up to the lovely futanari. She put her arms around the redhead, and pulled her closer. Mandy's naked penis rubbed along her tummy, sliding sensually against her own sheathed cock. "I'm your only sister, bimbette!" Mandy cooed before they pressed their lips together. At first the sisters had been a little weirded out by the idea of kissing each other. Would that make what they thought of as just their mutual hobby incest? Sure there was no law against incest for the futanari, but all their classmates would laugh and tease them if they let things go that far! For the longest time they had avoided the unspoken topic while playing with each other's genitalia. Neither had dared tell the other that they daydreamed about kissing a lovely sisterly face! Things had changed since their time on the roof. When they took turns popping each other's cherries, it just felt so natural and right to kiss the lovely partner you were laying on top of, while giving her the royal screwing she craved! They never really talked about it afterwards, but sucking on your sister's tongue and shoving your own into her mouth was thrilling! Sometimes they did like fucking each other in unison, each plunging her penis deep into the other's snug welcoming vagina simultaneously. It was a good way to speed things up if there was a serious lack of time! It felt fantastic when their sheathed cocks exploded together, but something always seemed to be lacking. Two futanari couldn't enjoy mutual vaginal penetration and still be able to kiss, if they didn't make use of Portal Technology! Their "plumbing" wasn't designed for it! The sisters had grown to prefer taking turns in the "Missionary Position", so they could gaze into each other's eyes, and press their lips softly together. Now, sometimes when nobody was looking, they'd kiss each other even if they weren't planning anything else! Kissing held a sensual thrill of its own! It was worth savoring the sensation any time they could risk it! Since they were best friends as well as sisters, they decided that it wasn't incest after all. It was just a sign of the love and respect they had for each other. Lindy ran her hands softly up and down her sister's warm back as they kissed. Loving hands traced the same path along her almost feverish skin. They parted lips with matching sighs. Lifting Mandy's long red hair out of the way, Lindy extended her tongue and gently licked her sister's earlobe in the way that drove her sister wild! Then she gave it just a tiny little nip with her teeth. Mandy's long legs almost turned to jelly. "Be careful!" she moaned. "Don't mark me!" The sisters were ever vigilant. Much as they would love to, they always used extreme care to avoid giving each other hickies. That would surely push their harmless hobby into the realm of incest! They could imagine the laughter if they ever showed up in class with matching love bites! Aside from that, their mommas would go suborbital! Mandy pushed her sister away. "Miss Futanari, your scent is driving me wild!" She said in a mocking impression of an aroused mono-sex that would surely anger both of their mono-sex mothers and earn Mandy a spanking! "I need you inside of me! Shove your dick-girl cock into me right now!" Lindy was a little startled. Mandy sure loved the dirty talk, but was it really necessary to use the D-G word? That was just so nasty! Kinda hot though, so Lindy didn't really mind. She stroked her sheathed cock. "I'll pump a baby into your belly, you dickless" Her voice dropped to a whisper "Broodmare!" "Lindy!" Mandy squealed with laughter. "I thought you didn't like talking dirty?" Calling a mono-sex a broodmare was about the filthiest insult you could ever say to one! It implied that mono-sex women were good for nothing but breeding with! Just last year a futanari candidate seeking to unseat the current governor had called her opponent one, dropping the "B-Bomb" in a live web cast! It very nearly cost her the election! The pundits claimed she only won because she spent the whole rest of campaign wearing tight clothes to show off her massive twenty inch package and the titanic orbs of her HH chest! Her real victory was due to the final debate. Dressed to impress with a plunging neckline that stopped just short of baring her massive nipples, you could actually see the swollen head of the futa's cock peeking up from within her massive cleavage! It was mesmerizing to see it bumping against the underside of her lower jaw as she talked. Silvery strings of precum stretched and smeared, making her chin slippery as she handily countered every argument and talking point. The ploy had worked. The busy governor had neglected to keep up her anti-pheromone inoculations. Right before the cameras, the governor started begging for a quickie behind the moderator's podium! The live feed was cut, but rumor had it that the fierce political rivals had fucked like bunnies in front of the live audience. The futa won by a landslide! The former governor had then quietly returned to the private sector, devoting her time to caring for her coming baby. Lindy blushed. "Uh sorry Mandy, Broodmare just sort of slipped out! Don't tell the mommas I said something so disgusting, okay?" Mandy grasped her sister's enveloped cock and gave it a friendly squeeze. "What, you don't think we should call momma Beth and Momma Molly Broodmares?" Lindy's cock gave a little happy jerk in her sister's hand when she heard her sister use the dirty word. "Not if we don't want soap in our mouths!" she grimaced. "Don't think momma Libby won't do that! I can still taste the bubbles after she heard me call Bobby next door an endangered species because he's the only male our age for miles! She still doesn't believe me that he thought it was funny and laughed his ass off! Besides, he always talks about that stupid conspiracy theory that says we aren't humans, and really come from outer space!" Mandy squeezed the cock a little harder. "Hey, you talk too much! If you aren't gonna fuck me, take that thing off and hand it over! Lunchtime won't last forever, you know!" "You asked for it, you horny slitch!" Lindy threw the redhead down onto the padded mat they had stolen from the gym. She was on top of her giggling sibling quicker then lightening! "I'm gonna fuck you so hard, your head will spin!" "Promises promises!" Mandy said softly as she lifted her knees and spread her legs wide. "Now get that cock in me! Even though you chickened out and stopped role-playing, hearing you talk dirty really worked me up!" Grasping her penis, Lindy rubbed it gently over Mandy's pretty little vagina. As always, she longed to feel that silky softness directly against her hard flesh, but Mandy didn't trust her to stop and pull out if they ever tried bareback for even one second. She didn't blame her. She sure as shootin' wouldn't let Mandy stick her naked prick up her! One little tiny slipup could make either one of them mommies just in time for their thirteenth birthday! The siblings moaned as the head of Lindy's cock found Mandy's opening, and slowly sank into tantalizing snugness. How much better would it feel to do this naked and uncovered? What would it be like to deposit a huge gooey load of sperm deep inside a fertile belly? Lindy forced that thought out of her mind as she buried herself in her beautiful sister's tight warmth. "We wasted too much time messing around." Mandy breathed as she felt the wonderful fullness of her sister within her. "Go on, just plow me, you have to hurry!" Muscles in her pert round bottom flexing; Lindy pulled back, and then rammed herself fully into her sister. Mandy looked so pretty when her mouth opened in a wordless "Oh" as she slammed into her again and again. Not to miss an opportunity, Lindy put her mouth to Mandy's, and the two kissed with a passion seldom seen in sisters. Writhing and rolling her hips, Lindy did her best to please Mandy as she took her own ease in the delight of her pussy. Mandy put her arms around Lindy's back, and crossed her legs over her sister's wildly moving body. She hugged Lindy tightly to her. Their breasts squeezed firmly together, nipple against nipple adding a wonderful electric thrill to their coupling. More importantly, Mandy's throbbing ten inches was sandwiched snugly between their flat tummies. Every one of Lindy's powerful jabbing thrusts made the muscles of both their stomachs ripple and caress her staff. It felt very nearly as good as getting one of her sister's energetic titty fucks! The two worked together. A year of eager happy practice had made the twelve year olds very accomplished lovers. The sisters had both taken dance classes, and this translated so well to lovemaking. Their bodies moved rhythmically and strong together as their release loomed ever closer. The warning bell rang, telling them lunch was over in just five minutes. The loud clang started Lindy, and she rammed a little harder and deeper. She came dangerously close to crossing their most important self imposed limitation. As long as you didn't achieve cervical penetration and actually enter your sister's womb, it wasn't incest! The sensation of pushing against Mandy's cervix and easing it upward to make room for her penis was just what it took to set her off! Lindy felt the convulsive power within her as her cock jerked. She was cumming! She moaned into her sister's mouth as they feverishly kissed. Mandy felt Lindy's release! The only thing saving her from a big belly was the almost invisible seemingly delicate barrier of the sheath encasing her sister's penis. If it was made of some primitive polymer elastic like they used in olden days, it would surely leak or burst! The ruptured latex would allow sperm to make her tummy grow! She would never admit this, but that weird little thought always tipped her over the edge! Her body writhed as she found her own release. Bodies shaking and spasming against each other had the desired effect. Mandy's cock throbbed, and the panting moaning sisters felt the underside of their breasts being bathed in spurt after spurt of warm gooey liquid. It was wonderful! When it was over, they flew into a flurry of well practiced routine. Lindy rolled off of her sister. The majority of the sheath was still bonded molecularly to her shaft. With no fear of slippage or leaks, Lindy didn't need to touch her cock as she eased the bloated mass out of her sister's body. Once it sort of stretched, elongating until it was narrow enough to pass through snug lips; it popped out with an audible plop. The indestructible material of the condom encasing the head of her cock was no longer invisible. Wiggling and wobbling, the expanded semen filled sack attained the rough size and shape of a cloudy pearlescent yellow-white baseball. The oscillating orb seemed to replace the normal head of her cock. She grabbed for the stack of paper towels they kept on the floor next to the mat. She wadded up a bunch, and held them protectively over her pussy to shield herself from the semen slowly sliding down her body and dripping from her breasts. She headed for the tiny sink in the corner and hastily washed up. Mandy grabbed paper towels too and began gingerly wiping at her own body, ALWAYS wiping up and away from her labia, to avoid getting even a tiny dribble of her own issue on her vulnerable unprotected vagina. Today was just too dangerous of a day to risk that! One tiny little drip of her fluid in the wrong place would make her belly look like a beach ball in nine months! Lindy very carefully released the molecular bond that locked the condom over her shaft. With practiced ease, she slid it far enough down and gave it the twist that would permanently seal her semen within the device. She stared at the warm wobbly ball for a moment. If the indestructible material could somehow burst against her, her own seed would splash all over her vagina and knock her up! Unconsciously she gave it a few hard squeezes before throwing it the corner where it bounced among all the other ones. The little room would really be stinky by now if they weren't all permanently sealed! Once her cock was bare, she carefully washed it with warm soapy water. Mandy was ready to wash now, and waited for her sister to finish. "Ew, that's gross!" "What?" Lindy asked as she aimed her penis and carefully urinated into the battered stainless steel sink. "I had to flush the pipes!" "What the hell!" Shoulder to shoulder with her sister, Mandy took a wicked piss too! The sisters giggled as they crossed steams. Clean, dressed and sated for the moment, the sisters leisurely walked down the hall towards their classroom. They spotted Lisa Wagner, the very pretty ten year old that had just joined the school as a late transfer student. She was wearing a snug little halter top that could hardly contain her massively swollen breasts, and a tiny little skirt that was almost too small to hide her impressive package. She waddled along, one hand on the small of her back; while the other did it's best to support the huge naked gravid belly. Her belly-button, temporarily an outie due to the presence of her ever growing womb, looked adorable as it jutted out toward them. As she drew closer, it was easy to see the two big dark wet areas around her large firmly swollen nipples. Like many futanari, Lisa tended to seriously over produce milk now that her lactation had started. Lindy giggled. "How's dairy production, sticky finger?" Lisa froze. "I hate it! I'm on my way to the nurse's office so I can pump myself out! I, I feel like my boobies are gonna burst! Someone played a recording of a baby crying, and it triggered my let down reflex! Everybody laughed at me when I started to leak! I forgot to bring an extra top, and now I'll end up smelling all sour by the end of the day!" Tears welled up in her eyes. "I thought you were nice, but now you're even calling me names! Please don't call me sticky finger! Everyone keeps calling me that, and it's not funny! It's mean!" Lindy felt bad immediately. "Oh wow Lisa, I'm really sorry!" She rushed up and gave the sobbing futanari a hug. "I was just teasing! I didn't mean to make you cry!" Mandy glared at her sister. "How can you be so mean to the kid? It wasn't her fault her first ejaculation caught her by surprise! How was she to know she was also dangerously close to Menarche? The poor thing managed to poach the very first egg her ovaries released!" Lisa looked up at Mandy, with tears running down her cheeks. "I never even had a period yet, and look what happened to me! I'm as big as a whale, but I'm still a virgin! It's not fair! I didn't do it on purpose, honest! I just forget to wash up after I accidentally squirted my very first load all over myself! I was all drippy and slimy, but it felt so good that I wanted to keep on going! I kept on stroking my noodle with my right hand, and my left hand just sort of went to my cunny all by itself! I swear I didn't notice I was pushing my goo up inside me!" She sniffed back her tears. "I only figured out what I did when I started puking my guts out every morning a few weeks later! I was so scared that I only wore baggy clothes for months! My mommy and sire finally noticed my baby-bump when even my biggest loosest top wouldn't cover my belly any more, and I had to admit what a dumb thing I had done! They lectured me for hours about how important it is to keep your goop away from your cunny, like I was some stupid little kid!" "I really am sorry, Lisa!" Lindy put her hands on the girl's back, and rubbed it soothingly. "That was a really stupid thing for me to say! Especially since my momma knocked herself up too! I promise I'll never call you that again, and I'll punch anyone in the nose if I hear them saying it too!" Lisa smiled. "Oh thank you Lindy, but I don't want you to get in trouble for fighting again!" She turned around and threw her arms around the older girl hugging her tight. "Uh-oh, I think I have a problem! Sorry about that, Lindy!" Lindy jumped back and shook the liquid from her boots as she watched the spreading puddle of water that was forming around Lisa's feet. "Hey Endora Lisa's about to pop. Her water just broke all over my feet!" "I'm on it, girls! Lead her to the nurse's office." Mandy looked a little scared. "Should we carry her?" "Huh, why should you carry me?" Lisa smiled bashfully. "I feel okay." She let out a gasp. "Oh, that's a contraction, but I still feel good!" Her penis began to slowly grow erect. "Oh, that's weird! I'm starting to feel really good!" She peered between swollen breasts at her growing erection as her belly rippled through the contraction. "Is that supposed to happen?" Endora chuckled. "That's perfectly normal, sweetheart. Blood flow is increasing to your genitalia as your cervix dilates Now hurry long, at your best speed. Walking is good for you. When the paramedics arrive, they'll give you a nice hand job to calm down and make you feel nice." Lisa giggled as she waddled along, flanked by her friends. "Oh goodie, I love hand jobs! My mommy does them for me when I go to bed at night, because she says she doesn't want me straining myself doing it since I'm lugging the twins around all day." She giggled. "Sometimes my sire does too." Her voice dropped to a whisper. "Last night they even took turns sucking on my noodle, while they gave me my very first actual real blowjob that I didn't do myself! It was a special present because my grades improved so much this semester! You should `a seen them argue over who got to have their mouth on me when I actually went pop! Mommy won, but that was okay. She didn't swallow all of it! They shared a whole bunch, squishing it back and forth in each other's mouths while they kissed!" Lindy smiled and nodded at the kid's happy story, but seethed inside as she heard laughter from the classrooms they passed on the way to the nurse's office. Her anger grew when she heard mocking calls of "Sticky finger" and "Selfcest is best, put your pussy to the test!" She was ashamed of herself for saying those things herself to the kid! "How are you feeling?' she asked rather loudly, trying to drown out the catcalls and laughter. Lisa looked up, face flushed. "I'm okay, really!" she smiled. "My mommy and sire said we can keep the babies. They're gonna raise them as their daughters. I'll be their big sister-mommy, so I can come back to school after I give birth." "That's great!" Lindy and Mandy looked at each other. The kid really looked happy, but things would be rough going. Everyone in school teased futanari students who were unfortunate enough to have a little solo-play mishap and give themselves a great big belly. Even if you had an actual partner knock you up by mistake, it was seen as a point of scorn if you got yourself preggered before choosing a mate and getting married! It was why the sisters washed so carefully after playing, and never ever not one time took the risk of going bareback for even just a second! Coming out of the portal station, Lindy and Mandy ran the rest of the way home. "I'll banish you to the moon!' Lindy giggled, referencing the ancient G-4 version of her favorite show. She agreed with a lot of the other fans. G-4 was the very apex of ponydom! "I can't believe momma Libby scored us all tickets for the grand opening of Disneyland: Mare Tranquillitatis!" Mandy cheered as they neared their home. "I told you, Mare in the Moon!" "Would you shut up about that dumb cartoon already? This is real life!" She grinned from ear to ear. "I love going to the moon!" They entered the house, and pulled up short. Their mommas sat side by side on the sofa, glaring at them. Lindy had a sudden nasty feeling deep inside. "Hi mommas!" she said with forced cheerfulness. "When are we heading for the Luna portal?" Libby crossed her arms over her abundant chest, and stared into the eyes of the daughter she had carried for nine months. "This sounds like something right up your bailiwick, young lady." Her eyes glinted. "Lindy dear, look into my eyes and tell me. Is there something you'd like to get off your chest?" Oh hell's teeth! Lindy could think of nothing to generate this anger, except for one tiny little thing she had "borrowed" this morning. She decided to try and brazen it out. "Uh, what do you mean, momma Libby? I haven't done anything wrong or bad since I got paddled at school because of the lawn mower!" "Because of the still, but that's vodka under the bridge." Beth shook her head. "I think you're right, Lib. It's all in the eyes. Lindy, you're a very accomplished young person, but you can't lie worth a bag of beans. Would you care to change your testimony?" "No momma Beth. It's the truth! I didn't do anything!" "Lindy, I'll give you just one more chance." Momma Libby said firmly. "Is there something you'd like to tell us?" Feeling trapped, Lindy turned to face her youngest momma. "Don't look at me, kiddo. I'm not bailing you out this time!" Molly said sadly. She glanced at her sister. Mandy looked just as scared. The first rule about creative lying is sometimes it's best to tell something that's almost the truth, but cops to a lesser crime. She didn't want to drag Mandy into this, after all! "Um, I, I guess you're talking about the condom, I, ah, borrowed, right?" "Borrowed implies the intent to return the item." Momma Beth wrinkled her nose. "I think we'll let returning it pass." Molly sighed. "Mom, don't be too cross with the kid. Don't you remember what being young and frustrated is like? I don't have a penis, but I sure remember!" Libby shook her head. "That doesn't excuse snooping in one of her mother's belongings, and actually stealing something! Now explain yourself, Lindy!" She thought fast. "I, I met somebody, A really pretty mono-lady. She started talking to me the other day, and when I told her how old I was, uh, she asked me if I ever had "Done It" before." "So naturally, you took the first opportunity to steal a condom from your momma Libby." Beth said in a quiet voice. "You have plenty of spending credit in your allowance debit account. There's only one reason I can think of why you would steal instead of buy." This was going better then she thought! The mommas didn't suspect that she and Mandy "played" together! "I, I didn't want you guys to know I broke my promise and went and scored me some tail!" Molly giggled, but quickly stifled herself. "We're very disappointed in you, sweetheart." Libby sighed. "Lying, stealing, and breaking a promise. I love you dearly, Lindy, but you have to learn a lesson. Order up anything you like for dinner, and don't stay up too late watching your old movies." She turned to face Mandy and continued. "Hurry up; we want to be on the moon by four." "What?" Lindy could hardly believe her ears. "You mean I can't go? That's not fair!" Beth got up and gave her a hug. "Is stealing from your family, and breaking your word fair?" Mandy spoke up. "Mommas, can't Lindy come too? What if I stole the condom?" Gasping, Lindy hastened to keep things from getting worse. If the truth came out now, she'd be in gigantic trouble for telling a great big fat lie to cover up her and Mandy's hobby! "I'm very sorry!" she cried, she would have tried to force some tears, but they were already flowing on their own. "I'll replace the condom I stole with my own debit account. Please can I go too?" All three mommas took a turn giving her a hug and a kiss on the cheek. Momma Libby hugged her extra tight, and gently kissed her forehead. "I'm sorry, Lindy, we all love you just as much as ever, but you need to think about what you did. There will be other trips to the moon. Maybe next time you'll remember this, and behave yourself." Lindy sulked in the corner of the living room as her family got ready to spend a wonderful evening riding all the rides and seeing the shows. She felt a tap on her shoulder. "Lindy, why didn't you let me take some of the blame? Maybe then we could both go, but if not, I could keep you company!" "Shhh!" Lindy looked around. "Are you kidding? If I can't go for stealing a stupid condom, how much trouble will I be in if they found out I made up that story about the mono-lady wanting me to fuck her?" She sat up, and tried to sound noble. "Just go! Think of your poor imprisoned sister while you're off having fun!" "Well you don't have to be such a drama queen about it!" Making damn certain none of the mommas were in the room, Mandy bent and gave her moping sister a very un-sisterly kiss! "Tomorrow morning I'll give you the very best blowjob I know how to give!" Lindy smiled. "Thanks Mandy! That gives me something to look forward to, at least!" An hour later Lindy was all alone. "Darn it, they really don't trust me!" she shouted at the empty house. "They set the stupid home security field! If I even step one foot outside, it'll contact them instantly! This sucks!" She could have ordered something nice for dinner, but she was too upset at what she thought of as her house arrest. "Prisoner reporting to the mess hall!" she snapped as she went to the kitchen. "Its bread and water for you, dirty slitch!" she announced, but poured herself a glass of milk, and fixed a couple peanut butter and jelly sandwiches. After she ate, her mood was quite a bit improved. "At least Mandy gets to have some fun! Maybe she'll bring me back a souvenir!" She decided to mess around with the DVD player she found at the thrift store for a single dollar credit unit. It was so old it was even pre-blu-ray! Most people wouldn't even know what the clunky oversize device was even for! Lindy worked for a while, rigging up a signal converter to try and feed an image to the family room wall screen. When she was ready, she closed the case back up, and hit the power button. "It works!" she cheered, as some kind of primitive menu screen appeared on the wall. "Now let's see if it plays!" She popped in one of the disks she had found while scouring flea markets and junk stores. It looked like a home burned, she thought they used to call it, movie. The title was written on the disk in somebody's sloppy handwriting. "Discode, what's that? Maybe it's just miss-spelled. That would be funny if it was Discord! There's always time for ponies!" Her eyes opened wide as the disk began to play. "Oh wow, that's not a pony!" she scanned through a little bit. "Oh cool! It's some kind of futanari porn cartoon!" She watched for a while, ignoring it when her penis began to swell and grow. "Damn, what's that clunkhead's problem? Why she is so scared people will know she's a futanari? Yo Futaba, just throw some precum on them, and then take your pick for a fuck buddy! What are you waiting for?" Her eyes opened wide. "I'd bust that blue haired slitch's nose if she tried to lock me in a chastity belt! Then I'd stick my dick up her butt and teach her who's boss!" It slowly dawned on Lindy that this disk was very old! "Damn, its pre-DDD!" she gasped. "They must have animated this long before the Dryden DNA Disaster a hundred years ago! No wonder they thought a futanari would be such timid little assholes! Nobody had ever met one yet!" Aroused, but disappointed, she clicked off the anime. "I can't fap to that! What a little stupid slitch! Why did they draw her cock so small? It looked like it was only about six inches!" She looked down at her penis, once again making a huge tent in her unitard and sighed. "I'm gonna go find something to really fap to!" she announced, as she headed up stairs. She wriggled out of the garment, and tossed it down the chute leading to the laundry system. She'd get it later when it was all cleaned and folded. "Let's see if the mommas have any good porn." She laughed the maniacal laugh she had been practicing lately. "You think I snooped before? You three have no secrets now! The Naked Detective is on the case!" She carefully began searching the huge master bedroom. It had to be big. The mommas had bought a specially built bed, big enough for the three of them to go wild on! The thought sent a delightful little shiver through her body. Sometimes she and Mandy would sneak down and listen at the door. They could hear all sorts of interesting sounds and cries coming from within! When their mothers were loud enough, they'd even take the risk of lying on the floor in the hallway, and indulge in a quickie "69" blowjob gulp-fest! There was nothing much of interest in the large dresser. Just the large assortment of undergarments you'd expect to find from three wives sharing the space. She turned to the closets. Three sets of double doors ran the length of the large room. The first one yielded nothing she hadn't seen this morning. The shelf over head was stocked with twenty boxes of condoms, as if Momma Libby thought they would somehow suddenly stop making them! Lindy didn't dare ever touch those again! She'd have to go back to swiping them from stores and unsuspecting classmates! She browsed through momma Libby's extensive collection of reproduction vintage dresses. Lindy loved how her sole biological parent dressed. When her momma wore one of those clingy dresses styled like the weird things people wore in the 1960's, Lindy usually had to run and hide until she rubbed off a couple quick ones to calm herself down. "I hope my titties get that big!" she whispered as she fondled a dress. "Momma Libby is the hottest futanari I know!" She looked in the next double doors. "Hey, why do momma Molly and momma Beth share a closet? That's stupid! There are three of them, and three sets of doors. Why pack the clothes in so tight?" At the third set of doors. Lindy noticed something for the first time. She and Mandy were always discouraged from invading their momma's bedroom/play area, and she had never noticed that one of the six doorknobs didn't quite match the others. It was an exterior door's knob, with a keyhole right smack in the middle, like you see in old movies from before they perfected security fields! Of course it was locked! "Now we're getting somewhere!" the naked blonde said while rubbing her hands together. "If it's locked, there has to be something good inside!" She went back to searching the rest of the room. Two long frustrating hours later, she found the key hidden up underneath the bottom of drawer. It was secured within a small case held in place by a powerful magnet secured to the antique wood of the furniture. Her long fingers could just reach to pluck it free. "It's always in the last place you look!" she said with a giggle. "Why do people say that? Should I keep looking a while?" Just being silly, she looked in a couple more places before bringing the key to the door. She slipped the key into the lock, and twisted it. "Oh holy crab cakes!" she gasped as she pulled open the door. "It looks like they bought out some kind of sex store!" She undid the latches on the second door and opened them both wide. There was a pegboard in the back of the closet that held many things. Some of them Lindy didn't even know what they were! She did recognize silken scarves and ropes. "Oh kinky, I wonder who ties up who?" Lindy blushed when she took down a riding crop. That was a little too much for her tastes! She giggled as she ran her fingertips over roughly conical rubber devices of varying sizes. "I wonder who sits on the butt-plugs?' she whispered, sort of tempted to try out a medium sized hot pink model. She took down a lifelike synthetic penis, and couldn't help giggling at the straps hanging off of its harness. "Poor mommas Molly and Beth, penis envy is so sad!" She wouldn't change a thing on her beloved mommas, but it would have been so nice if they were lucky enough to be born blessed by the Sainted doctor Dryden too! On one side of the board was a set of built in drawers to investigate. On the other side, several costumes were carefully hung. "Maid, nurse, police, Girl Scout, Japanese school uniform, and whatever the heck this is!" She looked at the shiny red rubber garment, realizing whoever wore it would be completely encased from head to toe. It closed up the back, like a pervert's idea of a scuba suit. Once molecularly sealed, the only two breaks in the slick smooth material were a hole for the pussy, and a sort of tube in the headpiece that looked big enough to keep the mouth wedged wide open to accommodate an extra thick cock like momma Libby's! The sort of padded mittens at the end of the sleeves didn't even have thumbs! She shivered. Once someone was sealed inside, they wouldn't be able to work the seal release and get out on their own with their hands looking like two big red balloons! She'd be totally absolutely helpless! Lindy held it up to her own body. If she really struggled, she just might be able to wriggle into it, if it stretched enough to accommodate her breasts and hips. That meant momma Beth wore it! In fact, all of the costumes looked like they were her size. Momma Beth must really love role-playing! She put the rubber suit back, trembling a little at the thought of momma Beth being all helpless while wearing it. She pulled open a drawer, and found a large onahole and some lubricant. "Why would momma Libby want this, when she has Momma Molly and Momma Beth to fuck?" She ran her finger over the soft flesh like material. "Maybe I'll give it a try. I think I'll like shoving my cock into something momma Libby fucks! Let's see what else they have to play with first!" The second drawer contained actual real antique handcuffs! Lindy picked up one pair and looked them over. They didn't have even the most basic biometric lock. There was a small hole, and she tried one of the tiny keys she found with the cuffs in the drawer. She giggled when it popped open with a metallic `snick'. She snapped it shut, and put it back in the drawer. "I guess those go with the police uniform. Wow, the mommas sure must have fun playing!" She opened the third drawer and took out a slender ornate wooden case. When she lifted the lid her eyes nearly bugged out of her head. "Mini-portals! Those things are super expensive!" she exclaimed. Her mind clicked, and a mystery was solved. "Oh fuck! That must be how momma Libby knocked herself up! She fucked her pussy through the portal!" Her cock surged harder at that taboo thought! "That must have looked so hot! Did she do it on purpose?" She giggled. "I bet momma Beth made her do it! Sometimes she gets so bossy!" Fingers trembling, she carefully slipped one into the right portal. It wiggled out at her from the one on the left! Heart pounding, she snapped the case back shut and put it away. "I better not even think that!" she hissed. "That way lays madness!" Instead she decided to try on the maid uniform. She could hardly button the low cut bodice over her breasts, and the frilly lace lined skirt barely covered her hiney. She put on the prime little lacy cap and looked in the mirror. She was astounded at how hot she looked! She never tried on anything really sexy before. The mommas were always careful with what she and Mandy were given to wear. It took weeks of begging to get even something as modest as their matching skin tight sheer unitards! Even then, they had to settle for ones with complete full length sleeves and stirrup legs when everyone else in school had tank style, high-cut legless ones that snuggled up delightfully in your butt-crack! This uniform was wonderful! "I look hotter then when I'm naked!" she gasped, as the rise of her cock lifted the hem of the tiny skirt. Using the antique looking feather duster she found hanging on the board as a prop, she struck a few poses while watching intently in the mirror. "Yes Miss, I clean for you. I do good job, no?" she said in her best cheesy French accent "Oh wow! I bet I could do a layout for PLAYFUTA! I'm one sexy maid! I could be Miss February!" she posed some more, turning herself on more and more. She took a deep breath. "Maybe it's time to shove my dick in that onahole! I'm turning myself on something fierce!" Her mind must have been playing tricks on her. Meaning to grab the onahole and lube; she accidentally pulled open the third drawer. She stared at the wooden case. "I wonder how it would feel?" she whispered as she slowly lifted the lid. Fingers trembling, she carefully picked up one of the twin three inch circles. With a little whimper, she lowered her hand, moving it slowly beneath her throbbing penis. Closing her eyes tight, she very carefully centered the device over her suddenly damp vagina by touch alone. Activating the molecular binder, she opened her eyes to stare at what she now held in the case. "My pussy." She breathed, feeling her warm exhalation against delicate lips. "My box is in a box!" Lifting it reverently from the case, she held her mons veneris like the precious delicate thing that it was. "Mandy says I give great connilingus." She said softly as she went to sit on the large bed her mothers shared. "I can suck my own cock, but I never ate myself out before!" Trembling in fearful anticipation, she bonded the second disk to the palm of her right hand. The three inch wide disk was slightly too large, but the overhand didn't interfere with the molecular bonding. She lifted her hand and gently stroked it against her face. "Oh, oh wow!" she moaned, as her whole body shuddered at the soft contact of silky lips dragging across a smooth cheek. She continued to stroke her vulva all over her face for a few moments, before she took a first tentative lick. She knew it from licking her fingers clean after solo playtimes, but it was still a bit of a pleasant surprise to discover first hand that she tasted different then Mandy. Was it wrong to think that her most intimate secretions tasted better then those of her sister's? She looked up into the large mirror that seemed set especially for anyone on the bed to see themselves in it. "I'm a shy little maid!" she said in a husky voice as she hid her mouth with her open hand. She started to lick, and it was wonderful! "I'm a shy maid, but I have a filthy secret! I like kissing my own pussy!" Lindy was eating out of the palm of her hand; body trembling as the direct sensual feedback automatically increased her connilingus skills to much higher levels. Lapping and licking, her face grew wetter and wetter as her arousal grew. She didn't realize just how muddled her thinking had grown when she forced herself to stop. "Dammit, I'm so horny I can't stand it!" She sighed. Just when she needed her sister the most, Mandy was up having a great time on the moon! She removed her pussy from her face, and stared at the lovely flower attached to the palm of her hand. "I can fuck myself!" she said with a giggle. "I bet that would be really cool!" She stood up, watching the sexy maid with the bobbing erection. "I wonder how I would as a mono-sex?" she mused, looking from the mirror to her hand and back again. "I'll try it like that! It'll be super hot!" With a little whimpering sigh, she removed the portal from her vagina, and looked in interest at what now looked like a huge hole clear through her hand. Slipping the open side over the head of her cock, Lindy felt the weight increase in her hand as her penis slowly emerged from her palm. She bonded the portal in place. She got off of the bed and stepped closer to the mirror. Just above her now normally positioned vagina, she saw a mirrored disk peeking out from under the micro-skirt, but no sign of her ten inch cock! "I look just like a mono!" she giggled. "I look so sexy!" Wearing her penis attached to the palm of her hand, she looked around the house for just the right thing to attach her cock to. "Oh wow, I just got a positively stellar idea!" Cradling her cock to her bosom as she ran, she went directly to momma Libby's craft room. As well as buying vintage dresses to have copies synthesized in her breathtaking dimensions, sometimes her momma would use old patterns and an actual real antique sewing machine to make her own old style creations. Lindy grabbed the dress dummy. She had some little difficulty lugging it back to the master bedroom one handed, but she couldn't bring herself to leave her cock anywhere unattended! Managing to lift it from its metal stand and base without bumping her cock too much, Lindy laid the headless half limbed mannequin on the bed and stared down at the specially formed transparent polycarbonate dummy. Futanari had little trouble retaining their figures, even after having babies. There was no need for an old fashioned adjustable dummy in case size or proportion changed. The sexy looking figure had been cast in an exact likeness of momma Libby from a full body digitalized laser scan. Even see-through, the big sexy boobs complete with thumb sized nipples, trim flat tummy, sexy wide hips and those lovely firm round asscheeks looked super sexy! It only had legs down to mid thigh, and the arms ended at the elbow, but she didn't need arms and legs for what she had in mind! Thankfully the simulated "Package" was detachable. It had to be. Momma Libby liked to switch from flaccid to erect so she could check the drape of the skirts and dresses she made against any state of arousal she may be in while wearing them. "I won't need that!" she giggled as she unplugged the droopy flaccid phallic form and tossed it aside. She detached the penis from her hand and bonded it on in its place! She looked at her handy-work, and giggled when she saw the detached penis give a corresponding happy twitch. "Just one more thing and I can start Operation Momma Simulator!" She turned to the first closet and opened the door. Reaching for a box of condoms, she froze. "They're all sealed boxes!" She stood there and whimpered, biting her thumb in frustration. "How can I get one without anyone noticing? If I open any one of those boxes, momma Libby would be sure to notice right away! I bet she counted them too. I don't dare just swipe a whole box! If I'm caught stealing her condoms again, the mommas will ground me for the rest of eternity, and probably cancel my allowance debit account, too!" "I'll just have to run out real quick and swipe some from a store!" Giving no thought to the outfit she was wearing, she ran to the living room. When her hand touched the knob on the front door, the room lights began flashing. "Miss Lindy, you are not permitted to exit the domicile." The security field AI droned. It didn't have the spark of life that Endora, and Lindy's other high level AI friends enjoyed, but that wasn't the worst feature. It would instantly report any breach of the programmed parameters! Lindy slowly took her hand from the knob. "Good! I, I was just checking to see if you were active." "Voice pattern analysis indicates an eighty-nine percent probability that Miss Lindy has spoken an untruth." Lindy sighed. Thank goodness! A lie detector result lower than ninety percent wouldn't be reported to her mommas! "I was just checking your voice analysis sub-routine." She said in as calm and collected a voice a horny stressed futanari could muster. "You seem to be running at your usual high efficiency." "Thank you, Miss Lindy." She breathed a huge sigh of relief when the lighting returned to normal. She stomped back to her parent's bedroom. "Crap! I wish Mandy were here!" she muttered as she stared at her dangerously naked penis. "I wish I had thought to swipe some condoms on the way home!" she kicked the closet door shut, hurting her bare toes in the process. "This bites toads! I'm so horny I wanna fuck! I don't wanna just settle for a stroke or suck!" She thought long and hard. "I don't trust Mandy to pull out, but I know I can trust myself. There's no way I'm crazy enough to risk even one drop inside me!" She thought some more, noticing a shining streamer of pre-cum sliding down the flesh of her detached shaft. "I better take some serious precautions first!" She ran and got her wrist data-com, and carefully scanned the bed and surrounding room. "I have to make sure I put everything back right!" With her cock still standing tall and proud on the dummy, she slid it over to the very edge of the bed. Working like a hospital aide, she carefully removed the coverlet, blankets and sheets. Folding them up into a big thick pad, she carefully placed it on the floor on the right of the bed. "Goodie, I knew they'd have a fluid proof covering on the mattress pad!" That would make clean-up much easier! She didn't dare get the pretty little maid uniform all sweaty, or worse, stained with semen. "Next time maybe I'll try to squeeze into the rubber suit." She giggled as she took the sexy outfit off and hung it back up. "Okay, now I have to go flush out the tubes!" She detached her penis from the dummy, and took it into her parent's private bathroom. Normally she had such a hard time pissing through a boner, but this was actually easy. There was no need to try and bend it down. She just held it over the toilet pointing straight at the center of the bowl, and did her best to relax. Once the stream started, she had to resist the urge to do something stupid like aim it at the tub. Maybe she could open the window as wide as the AI would permit and water the lawn! No, that would surely get her into trouble! She finished her business and blotted the head of her cock somewhat roughly, to try and tone down her edginess. That even felt good, so she held it under the facet and let out a shivery moan as she washed it carefully with chilly water, and lots of soap. "That took the edge off." She said with a smile. "Now let me do this!" She returned to the bedroom and repositioned the sexy dummy on the center of the mattress. Her knees felt like rubber as she climbed onto the bed, and once again bonded the portal right over the socket that the penal attachment plugged into. She took a deep breath. "Just in and out a couple times!" she warned herself as she threw a long leg over the dummy's hips, and straddled the surreal likeness of her singular birth parent. Her penis stood up tall and proud from the transparent crotch. Did it seem bigger then usual? She hadn't measured herself in a while, but she knew it was still growing! Lindy felt like it was taunting her as it stuck up in front of her tummy. It seemed to be saying "Look how deep you're going to take yourself!" She shuddered in a mix of fear and thrilled anticipation. She shook her head. "Just get the feel of bareback, Lindy!" she ordered. "Once you feel the first hint that you're gonna cum soon, jump right off and give yourself the wildest bestest titty-fuck oral combo you can possibly give! Whatever happens, keep those lips sealed over the head!" she giggled. "Drowning in my own cum would be a better fate then what would happen if I hose down the momma's bedroom!" Lindy rose up, and grasped her naked penis. Delightful shivers raced through her body when she felt the warmth of her pouty labia directly against the head of her cock as she gently rubbed it along the silky lips. "The commercials lie!" she moaned. "Wearing a Winger doesn't feel just like your naked!" she took a deep shuddery breath. "It's a million billion times better feeling if nothing is between you and your, um, the pussy!" If just the first touch felt that good, Lindy just had to feel more! Holding herself right at her opening, she slowly settled onto her own erection. "I, I'm so tight!" she cooed, as she let her shaft push deeper into her sheath. "I'm so warm and wet!" she couldn't help grinning proudly. "I'm tighter then Mandy is!" Whimpering and sighing, Lindy took more of her cock into her body. She only stopped when she felt a truly delightful sensation. "I, I think she's deeper then me, too. Or maybe I really did grow a little!" She had bottomed out. The head of her cock was nestled snugly against her cervix! She still had a little over an inch to go, but frankly was frightened that she would get carried away if she tried to engulf that too! Cervical penetration was supposed to feel like Heaven! She couldn't risk that! "Momma, I'm fucking you!" she cried to the dummy as she slowly started rolling her hips. Feeling more then a little embarrassed and narcissistic, Lindy started to ride herself. She would never hurt her sister's feeling by telling her, but this was even hotter then when she popped Mandy's cherry while up on a dirty grimy roof! She leaned down and started licking the smooth hard molded breasts as she humped her hips wildly. She pursed her lips around a nipple and pretended she was drinking warm fresh milk. Lindy decided she was glad she didn't go to the moon with her family! This was simply the most exciting and perverse thing she had ever done! Wrapping her arms around the dummy, she began rolling wildly back and forth with it all over the bed, trying to make it feel like she was struggling against a real live person. Lindy had done quite a lot of nasty story reading off of the cloud, and some unusual little deeply hidden fetishes started peeking through. "Momma no!" she cried, as she flopped onto her back and grabbed the dummy's ample hips. "Don't do this!" she started thrusting it onto herself, careful not to go that last tantalizing inch as she rammed her hard cock in and out of her pussy. "Momma no means no, you have to pull out! I'm your daughter! I can't be your broodmare! If you don't stop right now, you'll be raping a baby into me!" She was sinking dangerously deeper into her dark little fantasy! "Momma Molly, momma Beth, don't just watch! Save me! I don't wanna have momma Libby's baby! The whole school will laugh at me! They, they'll say I'm noting but a useless little broodmare baby factory!" Arms and legs hugging the dummy tightly to her fevered body, Lindy humped wildly up at it. She worked her cock in and out of her body, while pretending the dummy was trying to sire a baby in her womb totally against her will! `Momma no, it's my bad time of the month! I could get preggered because you refused to put on a Winger! Stop it, momma! You might squirt! Don't knock up your own daughter!" She looked to the side, and saw herself being fucked by the invisible futa! "Take my cock." She said while trying to imitate momma Libby. "My daughter is nothing but a little Broodmare now! You don't have a penis any more! That means you're only good enough to make babies!" She moaned as used her crossed legs to pull the dummy to her harder and faster, making it fuck her in a very realistic manner! "I'm going to make your belly big and round! I'll make your boobs fill up with so much milk, the other mommas and I will use it in our coffee!" Her dirty talk was inflaming her arousal. Lindy was sinking deeper, losing track of the dangerously swift approach of her climax! She was pressing the hard chilly polycarbonate breasts against her own when her racing heart and heaving chest told her things were about to get crazy and wet! "Gotta stop soon!" she gasped, writhing under her synthetic lover. "No, I, I have ta stop right now!" It took every ounce of self control she had to stop ramming her throbbing twitching cock in and out of her snugly clasping sheath. "I, I gotta calm down!" she whimpered. "Too close! I, I went too far! If I try and pull out now, I might accidentally ejaculate in myself! If I even more, I might shoot off a load! If, if I even sneeze I think I'll explode!" Heart racing and soul full of fear, Lindy lay perfectly still under her inanimate lover. Spreading her arms and legs wide, she quivered as the dummy lay balanced on top of her. Even breathing was making it move enough to continually shift the swollen cock within her body! She made the mistake of looking at herself in the mirror. Her cock twitched! "Oh no, did it leak anything?" she whimpered as she closed her eyes tight, and tried not to remember how sexy she looked while trapped underneath the dress dummy! Lindy bit her lower lip, trying desperately to force down the frightening specter of the intense orgasm that was just heartbeats away! "Keep calm! You can do this! Just, just don't move, and everything will be fine!" She tried her best to think about things like ice cold water and having tons of homework on a lovely sunny day. She tried to remember every horror video that had scared her senseless, and the awful time she was chased down the street by a big stray dog! She tried in every way to distract herself from the burning desire to just give the dummy one last big hug, and push herself over the edge! It was only minutes, but it felt like she hovered agonizingly and dangerously close to a belly filling orgasm for hours! "It's backing off.' She finally whispered. "Oh thank goodness! I, I think I'm okay now!" She took a deep breath, and felt herself slowly returning to some sort of control. "That was way too close! This is too risky! I just feel way too good inside to mess around any more! I better get out of myself and finish up in my mouth before something terrible happens!" Lindy was okay, that is until she rolled over to get on top of the dummy so she could climb off and give herself the oral and mammary attentions she needed to reach a safe climax. That's when the terrible something happened! Totally immersed in her dark little fantasy, the horny futa had completely lost track of her position a she rolled with her phantom lover all over the mattress. She gripped the dummy tightly and rolled them over one last time. Lindy felt the sudden sickening sensation of no mattress underneath of her! Teetering for a timeless second, Lindy screamed as she fell off the side of the bed! She landed on top of the dummy, which thankfully had landed on top of the folded bed linen and cushioned her impact. Her scream turned into a sort of gurgling gasp as her unthinkable dark fantasy became all too horrifyingly real! Deep within her body, she felt a sort of pop as something suddenly spread and gave way. There was no pain, only an almost indescribable joy as she finally fully and completely entered herself! As with all futanari and mono-sex women, she was remarkably elastic where it counted. The sudden sharp jab was all that was needed. She had read about it, but never in her wildest wet-dreams thought she'd feel it herself, while joined with herself! Instead of just pushing her cervix and uterus upward to make room, the head of her cock had breached that inner barrier, and popped right into the womb itself! "No!" she squealed as her body exploded! She frantically tried to lift off of herself before it was too late, but her feet tangled up in the bedding she landed on. Her feet slid, unable to gain purchase against the floor to jump up! There was no time for a second chance! Overwhelmed by her sudden and all powerful release Lindy could only grind herself against the dummy! Arching her back and crying out as her body throbbed, all was lost! Eyes opened wide with fear and pleasure, she felt the powerful rush making her urethra spasm as the warm thick liquid raced up her shaft. Her cock jerked, and the first powerful spurt of semen blasted directly into her fertile womb! Again and again muscles deep in her loins contracted. She couldn't do a thing to save herself! She was pumping a monstrously huge load inside of her own uterus and there was no way she could stop the eruption! The fear did nothing to prevent her from feeling the overwhelming joy of that release! Her hips bucked once, and then again, until she was humping like some mindless animal against the dummy, urging her cock into further spasming bursts of rich sperm laden semen! Hardly able to think, Lindy still knew full well that her fate was now sealed! Drool ran down her chin as the unbelievable waves of terrifying pleasure wracked her body. She had no way of measuring the duration of her fantastic release, but she ended up actively ejaculating up into her own belly for just a hair under a solid minute! "What have I done?" she sobbed when it was finally over. "Oh no, what have I done? It can't be today! Why did it have to happen today?" She put one trembling hand to her abdomen, and gently palpated, while counting calendar days on the fingers of the other. "Oh no, oh please no!" she wailed, feeling a large firm distended mass. The huge volume of ejaculate trapped inside her womb made it feel as if she were already a couple months pregnant! "I filled it up! I filled up my uterus with my own gunk! I stretched it out like a condom on my most fertile day of the month!" She sobbed. "I shot a hundred billion sperms into my own womb on the same day I'm ovulating!" She started to get up from her synthetic lover, but froze. "No, I can't here! If I pull it out, there's gonna be a flood! I'll never clean it all up before they get home! The mommas would kill me, and then ground me for life!" Her hands shook as she slipped her fingers under her trembling body to release the molecular bond attaching her penis to the dress dummy. "I have to hold it all in!" she whimpered as she slowly climbed to her feet, one hand clamped tightly against the mirror bright side of the portal. Thank goodness there was no seeping! The snug ring formed by her cervix tightly gripping her shaft just under the cockhead was holding it all back for the time being. She was holding nearly half a liter of virile sperm filled semen trapped inside her womb, but she didn't dare let any leak and make a mess! "I have to keep it all in until I get to the bathroom so I can try and drain it out! I have to hurry, before it's too late!" Instinct led her away from her parent's bathroom. She couldn't help thinking they'd know if she uncorked and dumped splooge all over the place in there! "Upstairs!" she whimpered. Both hands clamped tightly between her thighs, she began to slowly waddle out of the room. "I gotta get to our bathroom before it's too late!" Walking was a sheer sensual torment! Her still rock hard cock shifted and moved inside her with every step, feeling oh so dangerously good! It took her fifteen minutes, but she was okay until she reached the stairs. "Fight it!" she whimpered through clenched teeth as she lifted her leg for the first step. The sensation was incredible! Panting, she took one step at a time, resting as she tried to hold off the almost unbearable pleasure. She whimpered with joy twenty minutes later when she finally made the top without popping off again, but then she made another error. Goal in sight, she tried to hurry toward the bathroom. Two lurching running steps were all it took! "No, no more!" she cried as she once again pushed herself past the point of no return. Dropping to her knees, she again succumbed to the fantastic but terrifying feeling of pumping still more of her own seed into her swelling semen filled womb! Hand against the bottom of her cock, she couldn't stop thrusting it into herself, the short but powerful jabs prolonging the orgasm until it lasted nearly half a minute! Dazed, she lay on her side at the top of the stairs, holding the cock in placed to prevent ruining the brand new carpeting with her gigantic creamy-pie. Finally, using one hand to hold her penis in place, she slowly crawled the last few feet. She made it! She made it to the bathroom she shared with her sister! Lindy climbed into the tub, and flopped onto her back nearly a solid hour after her first explosion. She sobbed. "I gotta get it out! Maybe it isn't too late yet!" With shaking clumsy fingers, she released the bond of the portal centered over her penis, while locking the other in place over her poor abused vagina. She slowly lifted the penis occupied portal from her body, exposing inch after inch of still hard cock as it slipped slowly out of the pussy she was now holding in her trembling hand. As the bloated head popped out of her womb, she cried out in pure pleasure! When the portal was clear and she once again sported her now semen coated cock in its accustomed place, she let loose a few more powerful spurts that rained down onto her breasts and face. She clamped the portal against her right breast, holding her pussy tight against the firm orb. The seal of labia against firm but yielding breast was pretty good. Some semen was oozing out, but most of the load was still trapped deep inside. Some weird impulse took over. Lindy staggered to her feet. She closed her eyes and faced the ceiling. Moving quickly, she raised her right arm high and turned the portal so her pussy pointed down at her. Gasping and sputtering, she bathed her face in the warm gooey fluid that simply poured out of her. Lindy bore down, pressing her left hand tight against the bump in her belly, desperately trying to expel even more of the virile sperm filled liquid out of her bloated fertile womb. When it finally slowed to a dribble, she wearily sat in the big puddle of semen in the bottom of the tub. Lindy went down on herself with a vengeance! She somehow thought that if she could only eat enough of the warm goo, it would keep her from being knocked up! Long golden yellow hair all gooey and plastered against her skull, and body glazed and shiny with her slime, she raised her pussy to her face and went to work. Lindy performed cunninglingus on herself as if her whole future depended on it, because it actually did! She kept it up until her jaw ached, and she had climaxed seven more times. When her tongue couldn't seem to reach cum any more, Lindy opened her mouth wide and turning it sideways for a better fit, sealed her lips around her whole vulva! Sucking just as hard as she could, she managed to siphon a little more of her fluid out. She also ran into yet another problem! Cheeks concave with her massive effort, the negative pressure of her frantic sucking caused her engorged clitty to swell to nearly twice its normal generous size. Not thinking, she closed her lips directly around the swelling pink pearl, and thrashed her tongue against it as she sucked even more! She wailed when the sudden orgasm took her off guard. Shaking her head to try and regain her senses, she started to cry when she realized what she had done! She had dropped her pussy right into the puddle of cum she was sitting in! It was completely coated the slimy goo again! Everything she had sucked out was probably seeping right back in! She snatched it up and began licking and sucking it all over again! When she couldn't taste semen any more, Lindy stood up and took a shower. She knew you weren't supposed to, but she couldn't stop herself from trying to douche out her body with the hand held shower massager. It was really easy to do when you could hold the showerhead with one hand, and your pussy with the other. She whimpered and cried through yet a few more orgasms before finally giving up and putting her pussy back where it belonged by unbonding the portal from her vulva. She cried as she toweled off her sated body. It was no use! Her uterus was filled with a huge amount of sperm rich semen for over an hour! Her womb had actually been inflated by the force of the two massive spurting orgasms. The back pressure must have forced huge amounts of sperm up her fallopian tubes! Everyone knew how virile futanari sperm where! They could live for up to a week after being ejaculated, and remain just as motile! If a mono-sex or futa was within a week of ovulating, one little teaspoon was more then enough to shoot her down, no ifs ands or buts! An eyedropper full would do it, and she had filled herself up to capacity on her most dangerous red letter day! Lindy sobbed. She knew she had ovulated today! An egg was drifting down a fallopian tube right this second! There was no thought about odds, or that maybe she'd get lucky. It was a virtual impossibility that a healthy futanari WOULDN'T seed a fertile belly, even if it was her own! Lindy knew it with a certainty deep in her heart and soul, one of her sperm had already jumped on her egg! She could picture it frantically thrashing its wiggly tail around, as the head penetrated into the defenseless egg! It wouldn't show for quite a while yet, but she was already well and truly preggered! The fertilized egg would keep on dividing and growing, making her belly swell bigger and bigger as each month passed! She would be the school laughing stock! Lisa just had a little tiny mistake and they all made fun of her! What would they say about her if they found out what she had done? Clean and dry and very thirsty from the massive fluid loss she had just suffered, Lindy drank glass after glass of milk before going to her bedroom and collapsed on the bed. "Why did I do that?" she sobbed, humiliated tears running down her face. "Why did I risk everything just to feel what barebacking myself felt like? I, I could'a just stuck it in my hiney if I wanted a fuck that bad! I'm such a stupid clunkhead!" Lying on her back, she rubbed her tummy. After expelling all of the fluid she couldn't feel anything anymore. That would change soon enough! She'd feel it start to grow, and then people would start to notice! All her friends would point at her big belly and laugh! She couldn't even make up a story about some nameless lover. The blood workup at her next Med-Scan would prove to the world that she sired her own baby! Once that juicy little detail spread, she'd be the school joke! She taunted herself in a little sing-song voice. "Look, there goes Lindy! She couldn't get a mono to have her baby, so she had to squirt one up herself!" she sniffed back her tears. "Hey Lindy, I know you like "Do It Yourself" projects, but don't ya think you went a little too far with this one?" After spending over an hour curled up and crying like a little baby, Lindy shook herself out of it and hurried downstairs. "Get a grip! I can cry later! I gotta put everything back or everyone will know what I did just as soon as they get home! I need at least a little time I can pretend everything is still normal!" Lindy nervously crept back into the scene of the crime. She sniffed. "Oh fudge! It smells like sweaty sex in here!" The musty smell of her self induced hot baby makin' sex was causing her penis to once again rise to the occasion. She ignored it as best as she could and grabbed the dress dummy and put it back on its stand. "Where's the stupid fake cock?" she cried as she looked all over the room. She finally found it and plugged it back on. "I should have just grabbed the erect one, and diddled myself with that! But no, that would be too much like a good idea! I had to go and stuff myself up myself and splooge my own womb!" Eyes welling tears, she could hardly see while she dragged the stupid sexy mannequin back to its proper place in the craft room. Lindy worked for an hour making sure everything was back to normal, but as she worked, fear gripped her. "This is all Mandy's fault!" she said unfairly as she washed the crusting semen from the backs of the portals. "If she stayed home too, none of this would have happened! Now I shoved a bun in my own oven, and the whole school will laugh and make fun of me!" When everything was back in place, she compared the room with the recording she had made. Rearranging the pillows on the bed, she sighed. "That's perfect. They'll never tell, except for the smell." Thinking fast, she ran to the kitchen and grabbed a pack of instant popcorn. She pulled the activation tab and sat it on a plate. Before long, the whole house was filled with the aromatic scent of popping corn. "That should do it." She said while munching a handful. "Now I just have to figure out what I should do!" Sitting in the living room, the twelve year old ate some popcorn, paused to cry a little more, and then finished up her snack. "A trouble shared is a trouble halved." She said quietly, quoting one of Endora's favorite sayings. "Everyone is going to be so tired from their outing. I bet they'll go right to bed! I bet the mommas won't even open the secret closet for a couple days!" It was a serious risk, but Lindy took it! She went back to the room her mommas shared, and once again used the hidden key. Opening the third closet door, she grabbed the handcuffs, both their keys, and the slender wooden case containing the portals. "I'll sneak these back tomorrow. Nobody will ever know they were gone!" She whispered as she locked everything back up. "Sorry Mandy, but you have to be in on this! I can't face it alone! I'm just gonna have to see to it that you knock yourself up too!'' Lindy decided to just go to bed early. She brought the cuffs and portals upstairs and got herself ready for bed. Wearing her usual chaste white nightshirt with nothing but herself underneath it, she tossed her borrowed goodies onto her bed and then climbed up the ladder and scrambled onto the coveted top bunk. She stashed the stuff under her pillow, and set her wrist data-com to tingle-alarm when it detected the change in ambient light that meant someone had opened the bedroom door. Expecting not to sleep a wink, Lindy was out the second her head hit the pillow. Slowly opening her eyes, Lindy moved very carefully and shut off the annoying pins and needles sensation racing up and down her arm. She was glad she woke up at this stage. The next step was a rather sharp electric shock that would sometimes cause her to wet herself a tiny bit! She lay perfectly still, listening to Mandy getting ready for bed. She risked a peek at the display on her wrist. Three A.M.? Wow! It's a good thing tomorrow wasn't a school day! Lindy waited for nearly an hour. She struggled to stay awake, but her cock's obvious interest in her plan helped keep her alert. Quite as a mouse, she slipped the cuffs out from under the pillow, and slowly made her way back down the ladder. She smiled at her pretty sister, illuminated by the moonlight spilling through the skylight. Mandy was helping out! It was as if she knew what was in store! Lying on her back while peacefully sleeping, the redhead had her right arm up over her head, hand very close to the right side support for the upper bunk. Slipping into the narrow space between headboard and wall, Lindy closed a cuff securely onto the metal strut. It took her almost five minutes to slowly move the other side closer and closer to Mandy's hand. Holding her breath, she gingerly encircled the wrist. Click by click, she ratcheted the cuff closed, until it was snug, but not too tight around her sister's wrist. That was the hard part. Lindy still moved just as slow, but if Mandy woke up now, she'd still be able to finish the job! Plucking at the sleeve of her pajama top, Lindy ever so slowly pulled the fabric and dragged Mandy's left arm into position. Once her left wrist was secured, Lindy switched on the lights. Now she could relax and have fun with it! Mandy looked so lovely with her gorgeous red hair fanned out over her pillow. Lindy knew how to make her look even better! She grabbed the waistband of her sister's pajama bottoms, and tugged. Mandy moaned a little, but she didn't wake up as her bottom was laid bare for Lindy's appreciative gaze. She carefully slid the bottoms completely down her sister's legs, and just tossed them on the floor. "Someone's having a nice dream." She whispered, as she watched her sister's penis begin to stiffen and swell when the cool night air reached it. Not wishing to miss a thing, Lindy stood and waited until Mandy reached her full erect length and girth. She grabbed the sashes from both of their bathrobes, and tied one each to the footboard supports for the upper bunk. "Huh, what are ya doin' Lindy?" Mandy asked sleepily as Lindy spread her legs as wide as she could, and tied a sash securely around each ankle. "I'm just having a little fun with my favorite sister." Lindy answered as she pulled off her nightshirt and tossed it aside. It took Mandy a moment to notice, but she suddenly began to tug at her bonds. "Lindy, I don't like this!" Lifting her head, she could see she was no longer wearing her pajama bottoms. Eyes wide, she stared at her sister's erect and totally naked cock and put two and two together. She began to bounce up and down. "You better keep that thing to yourself, bimbette!" she smiled hopefully. "That is unless you look in my bag and get the condoms I managed to swipe at the Portal Transfer Station gift shop in Luna city!" "Thank goodness!" Lindy said in an attempt to keep Mandy unaware of her fate. She had to get her sister so totally worked up; that there would be no way she could hold back her explosion when Lindy sprang the "Main Event" on her! She giggled. "Wait right there while I go and wrap up!" She rummaged through Mandy's pack, and found the box with the smiling pretty doggie-girl on the front. Her cock was nice and hard, and with practiced ease rolled a Winger on and sealed it in place. She turned to face her sister. Putting the tip of her thumb in her mouth, she pretended to be deep in though. "Ever wonder what bareback feels like?" she finally asked in a soft voice. "What, are you crazy?" Mandy stared in disbelief as her cock gave a telling twitch. "You can't put me in you naked! We're both fertile as turtles today! Just one drop of cum, and I'd put a baby in your tummy for sure!" Lindy giggled. "That's why you're tied up. There's no way I'd trust you any other way! I'll let you feel what it's like for a little while. I'll get off way before you're ready to squirt, and then finish you off in my mouth. Maybe later you can tie me and return the favor!" She grasped her sheathed cock and gave it a little squeeze. "Thank goodness you brought these though! Now you no I'm not up to any funny business!" "Lindy, were you sneaking any of momma Beth's Cannabis cigarettes again? She gave you a serious spanking last time! You know better then to smoke those things before you turn eighteen!" "No I didn't smoke any of momma Beth's dumb imported marihuana!" she shook her head at the reminder of her favorite pet peeve. "That's a stupid law anyway! If futanari can have sex with grownups when we turn twelve, why do we have to wait until we're eighteen to smoke a little pot? It's not fair!" l "If you didn't smoke anything, then why are you acting so weird?" She wriggled and twisted, but there was no way she could get her arms or legs free. "You sound like a mono-sex that forgot her anti-pheromone booster inoculations! You don't know what you're saying! I could put a bun in your oven!" Lindy felt a sudden chilly fear race through her at the reminder of the "baking" she had already started in her very own oven. "I know exactly what I'm saying!" She sat on the edge of the bed and gently ran a fingertip up and down Mandy's pretty erection. She continued very carefully, trying to word things so she wouldn't be lying to her sister. "It's real nice of you to worry about me, but you don't have to. There's, uh, there's no way I'll let YOU knock me up tonight. I guarantee YOU won't pregger me! Do you think I'm dumb enough to let my own sister put a baby in my belly! I'll just sit on your cock for like a minute. You're no hair trigger! I know you won't squirt off that fast!" Mandy stared at her sister, trying not to think about how wonderful it would be to sink naked into her. "We decided! We'd never go "All The Way" without using condoms! There could be an accident! I could squirt a little by mistake, and that would make it incest! You know I make lots of precum! There's sperm in that! Not nearly as much as in semen, but there'd be plenty enough to get the job done! One little bit oozing out at the wrong time, and Bam! You'd be pregnant! What would people say? You know what everyone at school thinks about a futa that's so loosie-goosie she lets herself get knocked up when she isn't married to another futa! Look at Lisa! You even made fun of her! They'll tease and laugh at you every day! If they find out I'm the sire, we'd probably have to end up being home schooled to get away from all the nasty jokes and name calling!" "I noticed something, dear sister mine!" Lindy began to slowly unbutton her sister's pajama top. "You never just came right out and said NO!" Leaning down, she rained sweet gentle kisses all over Mandy's bare breasts. "Do you really truly not want to try it?" Mandy moaned when her sister sucked one nipple and then the other. "Do you promise to be really extra super careful?" she asked softly. Lindy came close to applauding. She knew her sister's horniness wouldn't let her down! "I swear it, Mandy! There is no way in the world YOU will be knocking me up tonight!" Mandy grinned sheepishly up at her sister. "I always wanted to know how bareback with you would feel, Lindy!" she giggled. "I mean it! With you, not anyone else! I always thought you'd smack me if I ever said anything though! Thank you! This'll be so perfectly arctic chill! I swear on my honor, I'll tell you when I get the first tiny inkling of a hint that I'm getting anywhere close to cumming!" she paused. "Could you untie me, first?" Lindy gave her sister a very passionate kiss. "You gotta stay tied up. It's the only way I can be sure of staying in complete control!" Was that ever an understatement! She doubted seriously being able to pull this off if Mandy was loose and fighting! Mandy giggled. "I understand, but I just had to ask though! You better believe I'm gonna tie you good and tight when it's your turn!" "I bet you will!" Lindy climbed fully onto the bed with her sister, and swung her leg over the prone redhead. "This is gonna be so good!" she whispered as she loving grasped the naked cock standing proudly in front of her tummy. "Oh, oh Lindy, that feels so good!" Mandy cooed as her sister gently rubbed the cockhead along her pretty pussy. "You're so smooth and warm!" she giggled. "Wet too! Please, put me in now, before I start oozing juice and it gets too dangerous!" Lindy lifted higher, and shifted forward. "I got you, Mandy!" she whispered as she lowered her body to accept her sister's penis. "Naked is better!" Mandy squealed as she slid deeper into the snug warm bliss of her sister's body. "Quiet!" Lindy breathed. "It was unlikely they'd be heard, but a momma walking in now would be disaster! "Keep it down or I'll have to stop right now!" "Sorry!" Mandy took a deep breath. "It's just that you're so hot inside! It never feels this good when I'm wrapped in a dumb Winger! I feel like my penis is gonna melt! I don't think I've ever been this hard in my life!" "You're not ready to pop yet?" Lindy asked just to make it look good as she slowly rolled her hips. "No, I, I'll tell you! I swear! I can hold off forever right now, at least for a little while!" Lindy started to ride her sister. She realized she had done Mandy a disservice. Lindy decided then and there that fucking herself wasn't exactly better then taking her sister's virginity! Mandy's naked cock inside of her was thrilling! She was already knocked up, but just knowing her sister's sperm could be released into her was so joyfully exciting! Skipping the stupid condoms just made any kind of sex so much more fun! "I, I'm sorry you didn't come with us." Mandy breathed, attempting to distract herself and extend the glorious feeling of being inside her sister with no protection. "It was fun, but I would have liked it so much more if you were there to ride all the rides with me!" Lindy lay fully over her sister, loving the warmth of their bodies pressed together. "That's okay. I'll go next time." She wriggled, rubbing their nipples together in the special way they both loved. "This is my best favorite ride though, so I really didn't miss a thing!" "Maybe when we all go again, you and I could sneak off and do it on the moon!" Mandy giggled. "You should see how extra bouncy momma Libby is in only one eighth of a "G"! The mommas left me at a show, and I didn't see them again for over an hour. They all looked flushed, and had big silly grins all over their faces, even though a security droid was scolding them! They think I don't know they all joined the two hundred thirty-eight thousand, eight hundred and fifty-seven mile high club together, and a robot caught them in the act!" The conversation ended as the sisters began to pant. Lindy was surprised. Her little nap seemed to have recharged her. After forcing herself to cum so many times while trying uselessly to get all of her semen out of her pussy, she was slipping ever closer to another release! "Are, are you getting close?" she gasped, trying to hold herself back while impaling herself over and over on her sister's beautiful hardness. Her plan would work so much better if she could leave Mandy hanging just seconds short of ejaculating! "No, I, I can go some more." Mandy moaned and bit her lower lip. "No, I lied! Lindy, you, uh, I think you better stop now! I, I'm almost there!" Her eyes opened wide, she was right on the ragged edge! "Stop, oh Lindy, you gotta stop! It's so good, but you just gotta get off me! Stop right now!" Much as she longed to just keep going, Lindy managed to keep her mind focused on the plan. Body shaking with her own need, she managed to scramble off of Mandy's cock before it could explode. She watched her sister's slippery shiny penis give several strong twitching jerks, but it soon settled down without expelling anything. "Lindy, I, I'm so sorry! I almost shot off!" she whimpered. "It was so close! I couldn't think! I almost didn't warn you in time! I hope I didn't leak any sperm!" She jabbed her hips upward in frustration. "I was so close! I don't think anything came out, but we need to do something to make sure!" Lindy made a big show of looking very closely at the dilated pee slit on the head of the quivering cock. She decided that if she hadn't knocked herself up already, she would have been pretty safe. Mandy was all wet with her own copious pussy juice, but she didn't think any actual semen came out of that pretty penis. Her sister moaned deep in her throat when she gave the lovely cock a little squeeze. A streamer of clear fluid leaked out, but there was no tell-tale white. "Nah, you didn't shoot me down." She giggled. "You wanna do some sixty-nine though, just in case?" "Oh yes, that will work great!" Mandy took a deep shuddering breath. "I, I'll clean you out real good with my tongue, while you finish me off with a blowjob!" Scooting around on the bed, Lindy gently lowered herself onto Mandy's lovely face. She sighed happily when her sister's long talented tongue went immediately into action! Leaning forward, she brought her lips within a hair's width of touching the hard flesh, and gently blew her warm breath against the head. Mandy moaned and tried to say something, but Lindy pressed herself firmly against her sister, actually sitting on her face! She had to pull back a little. Mandy kept right on licking, but while she was doing it, she started jabbing her hips upward, desperately trying to get Lindy to take the cock between her lips and suck! Wiggling and bouncing, Lindy listened to Mandy wheeze and gasp under her as she forced her sister to keep on licking! Mandy's own guilt kept her going! Knowing her sister was trying to make sure she hadn't left any sperm up there was very exciting! Whimpering, Lindy wrapped a hand around her encased cock and started to firmly stroke! "Get it all! Get it all!" Lindy panted, knowing if Mandy tasted any stray semen up inside her, she'd just think she was the one that put it there. "Get it all so you don't knock me up!" Mandy's squeals were muffled beneath her as that magical tongue shot into overdrive! Just knowing her sister thought she was helping was enough to drive Lindy over the edge! Humping and grinding against her sister's face like a wild animal, her hand flew up and down her shaft! "Oh yeah, that, that's it!" she cried, as she once again found her release. She loved watching herself ejaculate in a Winger. The first burst of cum filled the space around the head of her cock. Then more and more were added! Pumping wildly as her body shook, Lindy was astonished when she finally tapered off to the last oozing glop. "That much?" she said in wonder, a she gingerly poked her finger at the plumb sized pearlescent blob completely engulfing her cockhead. "I could be a porno-star!" she said as she slid off of Mandy, before her sister ended up suffocating! "Lindy, you didn't suck me!" Mandy wailed. "I need it! I need to cum so bad! Please do it! Let me in your mouth! You practically won't have to do anything! I'm almost ready to burst!" It was time! Sliding off of the bed to stand on shaky legs, Lindy reached up and slid the wooden case out from under her pillow and hid it behind her back. "I'll help you, Mandy, but wouldn't you like me to make you have a world record splooge?" "Just suck me!" Mandy blinked. "World record, how, and who's gonna clean it up?" Kneeling, Lindy carefully hid the case out of sight beneath the bed. "I'll make sure there's not much mess." She pantomimed sucking a cock, and then made some loud gulping noises. "You know I love eating your loads! I just feel like getting an extra big one tonight!" "Okay, just please make me cum! I think I'm going crazy!" "Just relax. Big sister will take care of everything!" "I'm a minute older then you!" Mandy moaned as Lindy began slowly running her fingertips all over her body. "Oh Lindy, please don't tease me!" she whimpered. "You know I won't tickle you." Lindy whispered. She knew just the threshold of her sister's delicate skin. She very carefully kept the pressure just right to stimulate, without casing her sister to erupt into a fit of giggles. She slid her hands all over those lovely breasts that matched her own, being oh so careful not to touch the nipples. Mandy's exasperated moans announced that she was already driving her sister crazy! "Your skin is so warm and smooth." She breathed, leaning down to begin letting her tongue take gentle little swipes against her sister's trembling body. "Oh Lindy, Oh, I, I like this!" Mandy moaned as her sister stopped using her hands. They had never played like this before! Her beautiful blonde sister was slowly crawling all around her, licking every single exposed area of skin! The tongue drew closer and closer to her cock, only to veer away at the last possible second when Mandy was sure Lindy would begin to lick her shaft! Mandy was almost vibrating now. Lindy got up. "Do you want to cum?" she asked softly. Prone on the bed, her sister frantically nodded her head. "Yes, Oh Lindy, I need it so bad that I'm gonna die if I don't shoot off soon!" Now it was time to get right to business! Lindy knelt next to the bed. Leaning in, she gently licked her sister's earlobe. "Would you like to cum inside a pretty pussy?" she whispered softly. "We shouldn't!" Mandy whined. "Oh Lindy, don't ask me that again!" She stood up. Standing with legs open wide, she used the index fingers of her left and right hands to spread the delicate lips of her labia. "Do you want to feel what it's like to cum inside a pretty pussy?" "Stop saying that!" Mandy's hips thrust up off of the bed, and she didn't even know she was doing it. "Give me a couple a tugs! I gotta cum!" "You said we're both fertile as turtles today." Lindy made a show of slowly rubbing her tummy, but was very careful of how she worded things. "Wouldn't you like to ejaculate way up inside a fertile belly?' she whispered, returning her hands to once again spread herself. "I bet you'd feel so good if you could just one time put your naked penis inside an unprotected pussy, and squirt out everything!" Frustrated tears filling her eyes, Mandy's bouncing grew wilder. "Don't talk like that! You, you don't know what you're doing to me!" Her penis ached for release, and Mandy couldn't tear her eyes away from her sister's lovely vagina! "Uncuff my hand, and I'll just jerk off!" she gasped. "Don't you want to slip your pretty penis right up inside a lovely pussy? I can help you do that, if you really want to!" Whimpering and moaning, Mandy closed her eyes tight. After about a minute of wild thrashing, she realized there was nothing she could do in this bound state to make her cock squirt! "Yes!" she finally cried. "I want to stick my dick in a pussy! I want to make a baby when I squirt right up in a fertile belly! Please Lindy, I wanna do it! Let me squirt a baby in you!" Smiling apologetically, Lindy settled to her knees and withdrew the wooden case from beneath the bed. "I'm sorry Mandy, but I wasn't talking about me!" She opened the box, and gently lifted out one of the portals. "What are you doing?" Mandy demanded as her sister placed a circular object over her vagina. She didn't feel the flat surface she expected from the shining silvery disk. Instead, it felt more like a ring surrounding her puffy pouty lips. "What is that? Is it a portal? Where did you get a portal set?" Lindy giggled as she showed Mandy the pussy she now held in the wooden case. "I got `em right downstairs! Didn't you know the mommas had these? I bet it's how momma Libby squirted me into herself!" "No!" Mandy watched wide eyed as Lindy attached her disembodied vagina to the palm of her right hand. She whimpered when Lindy returned to caressing her body. It was different now! She felt her pussy rubbing all over soft smooth warm skin! She couldn't block out the overpowering pleasure at the contact! "Stop it! Lindy, don't even think it! This is getting way wrong!" "You said you wanted to squirt into a pretty pussy!" Lindy placed her right hand over Mandy's mouth. Her sister moaned, but there was no way she couldn't start licking herself out! Who could resist going down on herself if given the opportunity? "You have a very pretty pussy!" Slowly lifting her hand, Lindy giggled as her sister strained, raising her head as high as she could in order to keep her tongue n her pussy for just a second longer! "You're just joking, right?" she gasped. "Lindy, it isn't funny! You know I didn't mean mine! I thought you were offering to let me fuck you!" "Do you want to see something really cool?" She didn't wait for an answer. Using her left hand, she gave Mandy's cock a few firm strokes. Shimmering clear liquid oozed out, and ran down the shaft. She extended her index finger and wiped it back and forth in the juice until the digit was all shiny and slippery. "Watch this! I'm gonna make my finger disappear!" Spreading her arms out like someone bragging about the size of the fish that got away, she slowly brought her hands closer together, finger pointing right at her sister's vagina. Mandy's eyes nearly popped out of her head. "Don't do it! Lindy, please don't do it!" she cried as the finger drew closer and closer to her detached pussy. "No!" She couldn't help wriggling at the sensation of a long slender finger slowly slipping inside! "There might be sperm! Lindy, there might be sperm on your finger! Get it out of me!" "You really think there's sperm there?' Lindy busily fingered the pussy on her hand, giggling as Mandy squirmed and writhed against her bonds as digit rapidly slid in and out. She only stopped when her sister's penis seemed to actually get thicker and started to quiver and jerk again. `Let me lick it out!" Mandy wailed. "Please Lindy; you might have pushed my sperm in me! Let me lick myself out some more, then you can roll a condom on me before you make a mistake!" Lindy looked sad for a moment. "Sorry Mandy, I'm not making a mistake. It has to be this way!" She put her hand to her face and gently slipped her tongue into her sister's folds. "Oh thank you!" the redhead cried as she continued to struggle. "No wait! Don't stop licking yet!" she watched in shock as Lindy slowly reached for her cock, with the hand her pussy was attached to! "No, get it away! Don't even make a joke like that! Keep my pussy away from my cock! It's way too dangerous! Don't do it!" "The pretty pussy is hungry." Lindy whispered. "The pretty pussy wants to swallow up a big strong cock!" "No it doesn't!" she cried, trying to edge away from her own advancing vagina, whimpering as the cuffs and robe sashes prevented her from getting from moving more then a few inches. "I don't wanna have my own baby! Why are you doing this? It wasn't my fault you had to stay home!" Lindy rubbed her hand slowly up and down the shaft of her sister's cock. She let the delicate lips of the vagina drag softly over the hard flesh as she thought about how to answer. "It really is your fault, Mandy! If you were home, you never would have let me do something so stupid!" "Do what?" Mandy cried, panic making her voice squeak. "What did you do?" "I sorta might have kinda got a little pregnant while I was playing with the portals!" "A little pregnant, are you crazy? How can anyone be a little pregnant?" "Okay, I stuck my penis on momma Libby's dressmaking dummy and went for a ride! I managed to stop myself in time, but I fell off of the stupid bed!" She blushed, thinking about the unbelievable power of her unexpected climax. "I rammed my penis so deep into myself that I just couldn't help popping off! I pumped out a ginormous load, while my cock was actually stuck up inside my womb!" She let out a little sob, but kept up the teasing of her sister's cock and pussy by rubbing them gently together. "There's no way in the world I'm not already pregnant! It was the most humongous load I ever shot off! It made my tummy stick out a little and everything! It took way too long to make it ooze out, and there's no way I could'a got all the sperm! Millions are still swimmin' all around up inside me, and I just know one has already made friends with my egg!" Mandy whimpered. Hearing her sister's dirty confession made her penis surge even harder! "Lindy, I'm so sorry, but how is preggering me gonna help you?" "I don't wanna do it alone!" She grabbed the cock with her left hand. Holding it steady, she set the head against the sweet little opening of the pussy attached to her right. "No Lindy, don't do it!" Mandy squealed. "I don't wanna pregger myself just because you did!" "You have to!" Lindy cried as with hand held flat, she pressed downward. It looked like some obscene illusion. As the hand slowly moved down, the hard penis vanished up into it! Inch by inch, Mandy's erect cock was disappearing into thin air, or more exactly, her sister's hand! "You're my sister; you have to do it with me!" Mandy gurgled wordlessly as she felt the incredible feeling of entering her own tight warm body. "Get, get me outta me!" she finally managed to hiss between clenched teeth. "Please Lindy, don't do this to me!" "You're doing it to yourself, just like I did!" Why wasn't being scared making her stop being horny? If anything, the thought that just one sperm leaking out while she was inside herself would forever change her life was turning her on even more! Her cock throbbed as it moved within her body. Mandy groaned as she tried to set herself against the fantastic feeling of being naked inside a warm tight pussy. It was her own pussy, but her stupid penis didn't seem to care! Bareback in a completely unprotected vagina felt so much better then she ever imagined it would feel! Her cock was totally oblivious to the terrifying fact that she at her most fertile peak right this minute! She didn't dare squirt out even just one tiny little drop of cum! "Lindy stop right now! Stop right now or I yell for the mommas!" "You better not! If you do I'll jump out the window and go over to Bobby next door's house. I own him a favor after calling him an endangered species. His sperm can't knock a futa up, but I bet he'll have hours of fun playing with a real live pocket pussy! I won't come back and release the molecular bond until the sun is up! Maybe I can even talk Bobby into letting his dog have a ride! I wonder if a Great Dane's knot can fit through the portal." "You'd never do that! You're just as scared of dogs as I am!" She opened her mouth to yell her head off, but only whimpered instead. Bobby was cute, so he would be okay, but there was no way she could let a dog get his knot stuck in her! "I, I can hold back! I just won't cum! You know I have more willpower then you!" "I know!" Lindy smiled. "Why do you think I got you so worked up? You may hold out for a little while, but you can't last forever! You said yourself that you're all ready to cum!" She started slowly wiggling her hand in the "so-so" gesture as she sped up the rise and fall of her arm. "I bet it won't take long at all!" Mandy gasped. It felt like she was being fucked by a fantastically passionate lover. Someone who was wildly rolling her hips while throwing herself repeatedly into impaling her tight hot body onto a big thick cock. It was only herself, and she couldn't stop it! "I can't cum!" she whimpered. "Oh please, I can't let myself cum!" She moaned, body beginning to move despite her efforts to lessen the feelings by lying perfectly still. "Oh, oh, I, I gotta hold it in! Can't, can't let a drop squirt out!" Lindy couldn't help herself. Watching Mandy wriggle and quiver as she fucked herself was so exciting! As her right hand went up and down the turgid penis, she grabbed her own with the left and began eagerly stroking! "You're so turned on by this, Mandy! I can tell! Your face is all red, you're panting, and your nipples are so very hard! Just relax and let go! You know it'll feel good!" She tried not to watch, but Mandy could never resist the beautiful sight of her sister getting in a good spank session! "Please, please no more!" she whimpered. "Too close! I, I'm so close I can't think! Don't make me do it!" "Do what?" Lindy said sweetly. "Tell me exactly and maybe I'll stop!" "Don't m-make me pregger myself!" she squealed. "Don't make me give myself a big belly! Don't make my boobies fill up with milk!" Lindy noticed something. As her sister protested, her sexy hiney started rising up off of the bed! She stopped moving her right hand. Mandy sped up, frantically fucking up into her own vagina! "Do you really want me to stop?" she asked huskily, stroking her own condom covered cock even faster. Panting like she just ran ten laps in gym class, Mandy moaned. It was like she couldn't even hear her sister. "My boobies will leak milk! If I get preggered, milk will make my boobies get so much bigger!" She shook her head, as if trying to clear her thoughts. "Get my pussy offa my cock, before it's too late!" Lindy lowered her hand, until she could feel the little jarring bumps of Mandy striking her own cervix with the swollen head of her massive erection. She decided to try a little experiment. "Mandy, if your boobies leak. Can I drink some of your milk? I'll let you drink mine if you do!" "Don't say embarrassing things!" Mandy squealed. Picturing Lindy with milk filled breasts and the idea of actually tasting the fluid seeping out pushed her that tiny last step! "Oh no! Get it away! Get my pussy away from me right now!" she cried, but it was too late! Mandy succumbed! She felt the rush begin deep inside, as the dangerous fluid raced up her throbbing cock! Lindy watched with wide eyed wonder as her sister strained against her bonds. Muscles stood out as she lifted her butt up as high as she could! Whimpering, she let go of her own cock, and thumped her left hand sharply against the back of her right. She felt the sudden giving of resistance, and her hand lay flat against her sister's quivering body! "Lindy!" Mandy managed to cry as she felt herself pop through that most sacred of barriers. The head of her cock was inside of her womb, and she couldn't stop the explosion! Shaking her head from side to side on the pillow until her lovely red hair covered her face, she could do nothing but ride out wave after blissful orgasmic wave as she emptied herself completely into her own uterus! She was at her most fertile today, and absolutely filling herself with her own semen! That fevered thought only seemed to increase the power of her convulsive release! Hand against her sister's body, Lindy could feel Mandy writhe and jerk her release. Just as she had done hours before, Mandy was impregnating herself! It was simply the sexiest thing she had ever seen! Crying out with her sister, she started jerking her own cock again. In seconds she released yet another load into the lifeless envelope of a condom the likes of which she and her sister wouldn't need again for quite some time to come! As their breathing slowly returned to something approach normal, Lindy dropped to her knees. "Mandy, don't hate me!" she cried, not daring to look at her sister's face. "I don't know what I'd do if you hated me! I just needed you to be just like me! If I got all big and pregnant and you didn't." she choked back a sob. "You might go out and find a girlfriend!" "That's why you did this?" Mandy asked in a quite voice. "That's why you made me knock, um, knock me up?" She couldn't help herself and started to yell. "Lindy, how stupid can you be? I don't want anyone else! Sure screwing a mono-sex will be fun, but that wouldn't make me ever want to leave my sister! You dumb blonde bimbette; don't you know I love you?" "You, you do? I love you too!" Lindy's joy was swiftly overtaken by guilt. "Oh Mandy, what have I done? How can I ever make it up to you?" The sisters heard the sound of multiple feet running up the stairs, and panic set in! "What is all this commotion about?" momma Beth called as she flung open the door. Her eyes quickly took in the handcuffs, and the fact that Mandy didn't seem to possess a penis at the moment, just her sister's hand resting right over where it was supposed to be. "Oh my goodness, ask a stupid question!" She tried to pull the door back shut, but her two wives were hot on her heels and pushed her in as they fought to enter. "Mommas, I can explain!" Lindy cried. She made the mistake of snatching her hand away from Mandy and hiding it behind her back. Mandy cried out as her cockhead roughly exited her womb, and lapsed into a secondary explosion. Several strong spurts of semen shot upwards to plaster against the underside of her sister's bunk. Lindy saw that and gasped. She tried to hold Mandy's pussy tight against her back to stanch the leak, but she could feel the warm fluid slowly oozing down her butt-crack! Molly dove for her daughter's legs and fumbled around as she tried to untie the sashes from the whimpering futanari's ankles. "Honey, are you hurt?" she asked as any worried mother would. "Momma, I'm fine!" she took a deep breath. "If you find the handcuff keys somewhere, you can let me worry about untying my legs!" Libby stared at the child of her loins. "Just what the hell are you doing, Lindy?" she asked angrily. "Show me what you're hiding!" Beth couldn't help laughing as she openly stared between Mandy's lovely thighs at the shimmering silvery disk obscuring her vagina from view. "Like mother, like daughter! Libby, I already know what she's hiding!" "Well I don't!" Libby stomped her foot, causing her breasts to bounce quite fetchingly beneath her night-gown. "Lindy, show your momma this instant!" "Yes momma Libby!" Trembling with fear, Lindy whipped her right hand from behind her back and extended it out to her mother. That wasn't the smartest thing to do! Simple physics took over! A huge gobbet of semen kept right on going when her hand stopped moving, and spattered all over her beautiful birth mother's face! "Oh, oh shoot!" Lindy moaned, as Mandy's pussy continued to dribble copious amounts of semen onto the floor. Wiping her eyes, Lindy stared in shock at the gooey creamy-pie oozing vagina attached to the palm of Lindy's hand. "After what happened today, you went through your momma's things again?" "I didn't steal any condoms!" Lindy cried defensively, too late remembering the distended baseball sized semen filled globe hanging off the head of her rapidly shrinking cock. "Really, this one isn't stolen, honest!" Beth looked around and picked up the condom box off of the nightstand near the bottom bunk. She looked closely at the words printed on the bottom. "Intended for Lunar sales only, not for Earth distribution? Mandy dear, is there something you'd like to add to this discussion?" Mandy was sitting up on the bed, gingerly prodding the swollen little bulge visible in her tummy. "Um, that condom is kinda stolen, uh, I guess." She pressed down on the firm mass of her womb, inadvertently accenting her words with a nasty bubbling "Slurp" sound as the flow of semen increased from the palm of Lindy's hand. "I, I sorta shoplifted on the moon!" she cried, trying to drown out the wet plops of slightly used semen hitting the floor. Molly stared at her daughter. "You shoplifted? Honey, you're always so good! Don't let your sister be such a bad influence!" Mandy glared at her mother, words just spilling out before she could stop them! "Don't say Lindy is a bad influence! She isn't! She's gonna be my wife!" Libby grabbed a desk chair and pulled it over. "Sisters can not get married! I'm nipping this in the bud right now!" She sat in the chair and motioned for Lindy to come closer. "Assume the position Lindy! You need a good spanking to remind you not to get into such trouble in the future!" "Momma, you can't spank me!" she cried. "You can't spank a pregnant futa, it could hurt the baby!" "Pregnant? Mandy's the one leaking goo, that's her, uh, her, um, her girl part on your hand! How are you pregnant?" "I just am! I, I played with the portals while you guys were on the moon!" She couldn't help a little sob. "I had a little problem and couldn't get out of myself in time! I filled my oven with my baby-batter by mistake!" Libby gasped as she witnessed history repeating itself. "You knocked yourself up? Get over here and lay across my lap this instant!" Beth sidled over to her futanari wife. "Honey, how are you going to lay her over your lap?" She gently ran her finger over the tremendous tent straining up against the nightgown Libby wore. "There isn't any room!" "See, you can't spank me!" Lindy yelled. "Being pregnant proves I'm too old for spankings anyway!" Molly put two fingers to her lips and let loose a shrill whistle. "TIME OUT!" she lowered her voice and smiled sweetly at her daughter. "Mandy dear, could you please explain yourself a bit clearer? I'm upset that you stole from the gift shop, but please don't think that means I won't listen carefully to anything you have to say." Mandy took a deep breath. "Lindy and I love each other!" she looked up at her frightened sister. "Lindy, will you marry me?" "Oh yes! Mandy, I want to marry you! Yes! I say yes!" Libby moaned. "But you can't! You're sisters! I won't let you!" Beth was carefully watching Libby's lap. "Methinks the Futa doth protest too much." She giggled, and ran her finger over the rapidly spreading wet spot at the tip of the tent pole. "Admit it Lib, this is getting you turned on! My pheromone inoculation doesn't keep me from smelling how aroused you are right now!" "It is not me! It, it's just the smell of Mandy's semen!" she wiped at her messy face. "You know how my own works me up! I have an accidental boner, that's all! No daughters of mine will marry each other!" Molly sighed. "Mother, when did you become such a damn hypocrite? Sisters can't marry, but mothers can marry daughters? Explain the logic of that to me!" Beth gave a quick thumbs-up to her daughters behind Libby's back. "The law is on their side, Lib. They're both futanari so incest does not enter into it. They're both over twelve, so they can legally pick whatever bed mate they desire. You can't fight this! If our babies want to marry, I say let's give them all the support we can!" She smiled at the sisters. "With babies of their own on the way, they'll need all our help." Libby sighed as she stood up. "No, I guess I can't!" she gave Lindy a big hug, not noticing the sudden spurt of creamy-pie being deposited on her back. "You know I want whatever makes my babies happy, don't you, Lindy?" "Yes momma!" Libby knelt and put her arms around Mandy. "That goes for you two, darling! I want both of you to be as happy as your mommas and I am!" Lindy sighed, finally feeling the knot in her tummy loosening. "I'm really sorry for all the trouble I caused!" she smiled a nervous little smile. "I'm glad I learned my lesson! You don't even have to bother hurting your hand by spanking me!" "Kiddo, I wouldn't go that far!" Beth sat in the chair and pulled Lindy closer. "You went in our things, not once, but twice!" Her face turned red. "You saw several garments I had no wish for you to see!" "What? Oh, oh no! I didn't see the red rubber suit, honest!" she gasped as she was pulled down. "No, please don't! I was just kidding! I didn't see anything! You can't spank me! I'm pregnant with my own baby! It'll be double child abuse!" "Don't shit a bullshitter, kiddo!" Beth sighed. "We all know that the little peanut in your tummy won't even notice this." "I'll notice! Please don't! I learned my lesson, honest!" Struggle as she might, she couldn't stop momma Beth's hand as it rained stinging blows onto her bare bottom. Mandy stood up, hopping from foot to foot in panic. "Lindy, don't try and block with your right hand! I'm still there! Left! Use your left hand only! Don't make her smack my pussy by mistake!" Thankfully her sister was able to listen, and keep the precious object still attached to her hand safe and free of spanking by proxy! After ten sharp slaps, Beth let Lindy up and gave her a kiss. "I love you, honey, but don't go messing with things that don't belong to you. Okay?" "Yes momma!" Lindy sobbed rubbing her left hand on her sore bottom, while holding her right free from touching her body. "Mandy dear, there's also the small matter of your shoplifting endeavors! I love you and Lindy with all my heart, and will support your marriage with all my soul, but no daughter of mine will ever steal!" Molly pulled the redhead over her lap and got to work. "I'm sorry!" Mandy cried, as she received her lesser sentence of five good wallops. "I swear I'll never shoplift again!" When it was all over, Libby just stood in the middle of the room and stared at a large pearlescent puddle on the floor. "There's so much semen!" she gasped, slowly putting a hand to the hardness under her nightgown. "It's simply everywhere!" Beth sighed again. "Molly dear, help me get your mother to bed, before she makes this family even more confusing then it already is!" "Look at all the semen!" Libby said to her daughter/wife as the younger woman took her hand. "Mandy knocked herself up, and it's all leaking out of Lindy's hand!" "Yes mom. I noticed. Come on. I think I know somebody who needs a good screwing to calm her down!" The sisters watched as momma Beth and momma Molly each took one of momma Libby's hands and led her from the room. Lindy smiled shyly as she reached over and released the bond of the portal in her sister's lap. "I love you Mandy!" she said softly, enjoying how it felt to say it. "Don't take this the wrong way, but marrying you is just the first step! Five is my lucky number!" Mandy giggled as she put a hand against her vagina, marveling at the huge amount of her own seed still dribbling out. "I'm way ahead of you! I bet we'll be joining into the momma's marriage before we're fourteen! Three futa's and two monos is the perfect mix for happiness! I know we'll convince them of that!" Lindy smiled. "Until then, nobody at school will make fun of us now! Instead of everyone laughing and pointing, we'll be the envy of the school for being married, and getting started early on our own family!" The brides to be kissed, keeping themselves awake and energetic until long after the beautiful sunrise announced the first day of their new and happy lives together.
