Alex and Andrea ran at an easy pace together down the abandoned 
maintenance shaft, their bare feet leaving only trace footprints in the 
light sand covering the smooth, rock floor. Like all children on Mars 
Colony, the two ten-year-olds were naked from head to toe.

They stopped when they reached a 7-foot-diameter opening on the left 
side of the tunnel. It was an emergency bunker used by the crews who 
had built the tunnel, but it had long-ago been abandoned. It was dimly 
lit by an array of optical fibers leading from a collector on the 
surface. The poor quality of the lighting suggested that the collector 
wasn't maintained and was partially covered with sand. They cautiously 
peered inside.

The room was about 10 feet square. To the left, they saw shelves filled 
with containers of water, medical supplies, and food. In the corner 
were two large cylinders of oxygen. From the looks of it, the food and 
medicines were probably expired, but--even at their age--Alex and 
Andrea knew not to touch the supplies: they might, someday, mean 
someone's survival.

Along the opposite wall from the supplies were several bunk beds with 
vinyl-covered mattresses that looked surprisingly clean, as if someone 
were keeping up that side of the room. Alex and Andrea looked at each 
other and giggled before entering the bunker.

Andrea threw herself onto one of the lower bunks, and Alex wasted no 
time climbing on top of her. He pressed his nose to hers, causing them 
both to giggle some more.

Andrea was happy when Alex pressed his lips to hers, but she was taken 
aback when he pushed his tongue into her mouth--he had never done that, 
before. Part of her thought, "Ew, gross! Boy slobber!" while another 
part welcomed his forced intrusion into her body. Before she could 
decide between the two, Alex moved down to her flat chest, gently 
pinching one nipple while suckling on the other. Next, he moved even 
further down her body, and when Andrea spread her legs for him, he dove 
right in.

His 11-year-old sister, Colleen, had been training him since he was 
seven, and he frequently practiced on his younger sisters, Candice and 
Lauren (currently 8 and 7, respectively), so Alex was quite adept at 
pleasuring girls this way; however, this was the first time he had done 
it with a girl who wasn't a sister. The gasps and moans from Andrea 
assured him he was doing it right, and he didn't let up until he knew 
she had orgasmed.

As Andrea lie panting, Alex moved up her body, aligning his penis with 
her labia. He gave a gentle push, and his penis slid along her slit. He 
pulled back and tried again, with the same result. After several failed 
attempts to penetrate her vagina, Alex reached down and used his hand 
to guide his penis to his target. This time, the tip of his stiff penis 
passed through the ring of muscles.

Despite having come here with Alex for this express purpose, Andrea was 
still surprised when his penis actually entered her vagina. 
Reflexively, she clamped down to prevent his entry, but he was already 
inside her. She relaxed a little, allowing him to push in a little 
farther. Eventually, he had his full three inches inside her body.

Alex savored the moment. He had waited a long time to get here--with 
this particular girl. He might have had earlier success with some other 
girl, but Andrea was the one he wanted as his first. It took a lot of 
flirting, and hand-holding, and kissing, and massaging to get here, but 
it had been worth the wait.

Andrea thought of all of Alex's pestering, and she was now glad she had 
relented. Alex was incredibly cute--and a lot of fun to play with--but 
she hadn't thought he was the right boy to be her first. Any remaining 
doubts were now gone. Alex belonged right where he was.

Andrea's older sister, Lisa, had warned her that young boys were 
usually quick the first several times they were with a girl--the first 
three boys Lisa had been with had cum before they had gotten all the 
way inside her on their first couplings--so Andrea was surprised by how 
long it took before Alex finally started thrusting. When he did, he was 
slow and deliberate.

As much as Alex wanted this, he was determined to make Andrea's first 
time so good that she would lose interest in any other boys who might 
otherwise tempt her. The urge to thrust wildly was strong, but he 
fought to control himself. Despite his efforts, his pace gradually 
increased.

When he sensed that Andrea was close to orgasm, he lost all control. 
After a dozen or so rabbit-like thrusts, he pushed hard against her 
body and grunted loudly. Andrea cried out, and the clenching of her 
vagina on his pulsing penis sent Alex into a state of euphoria.

Andrea wrapped her arms and legs tightly around Alex's body, and her 
vagina tugged on his stiff little penis, desperately trying to draw it 
deeper into her vagina. She felt it kick and buck, and she imagined 
that it was pumping her vagina full of semen, even though she knew for 
certain that Alex wasn't yet producing any.

After more grunting, Alex finally collapsed onto Andrea. The two 
pre-teens struggled to recover their breath. When they had, a little, 
they both giggled, giddy with the wonder of this new experience.

"Wow, little brother! That was intense!"

Andrea stiffened in panic, but Alex's limp body on top of hers 
prevented her from moving. She looked toward the door and recognized 
Alex's older brother, Thomas, standing just inside the room with his 
girlfriend, Stephanie. The two twelve-year-olds had amused smiles on 
their faces.

Alex pushed himself up slightly, turned his head toward his brother, 
and gave him a self-conscious smile. Before he could climb off Andrea, 
Stephanie was climbing on top of him. She supported her own weight with 
her knees and forearms, but effectively prevented either Alex or Andrea 
from getting up.

Thomas knelt on the bunk behind Stephanie and slipped his already-stiff 
penis into her already-wet vagina and began slowly thrusting.

Alex was tickled by Stephanie's warm breath in his ear as she 
whispered, "This is a good place--like we told you--right?" Alex 
giggled.

"Is your little penis happy, now?" Stephanie continued to whisper, 
causing Alex to giggle even more.

Stephanie smiled at Andrea over Alex's shoulder as Thomas continued to 
work his 4-inch rod in her vagina.

"I'm not going to ask if he was good because I know he was: It was 
pretty obvious!"

Andrea blushed.

"Mmmm!" Stephanie closed her eyes briefly and purred. "It must run in 
the family!"

Stephanie rubbed her body against Alex, knowing that it would make his 
penis stiff, again. As it hardened, Alex squirmed a little, aligning 
the head with the entrance to Andrea's vagina, and found himself once 
again inside her. Stephanie's body prevented him from fully thrusting, 
but he worked his penis in Andrea's vagina as best he could. By the 
time Thomas was grunting, so was Alex.

Stephanie stood up with a satisfied moan. "There's nothing better than 
a pussy full of cum!" she declared, placing one foot on the bunk and 
inspecting the glob of semen leaking from her vagina. She caught it 
with her fingers before it dripped onto the floor then wiped it onto 
her thigh.

"Last week," she said with a chuckle, "Thomas did me right before 
school started, and I went to first period with his sticky mess on my 
thighs. I let it dry and went the whole day with it there for everyone 
to see and smell!"

Alex was now sitting up on the bunk. Thomas was kneeling behind him 
with his hands on Alex's shoulders. He gave them an affectionate 
squeeze, then began massaging them.

"So, little brother, was it worth waiting for?"

Alex blushed and remained silent, but Thomas already knew the answer. 
He loved his little brother--and he loved teasing him. He also loved 
looking out for him, and it was he who had helped Alex win Andrea over. 
He gave Alex a strong hug around the chest, kissed him on the neck, 
then climbed off the bunk.

With her legs still spread, Andrea sat up and checked herself for any 
leaking fluids. She knew Alex hadn't left any in her, but she still 
looked, hopefully. She longed for the day when Alex would give her her 
own "pussy full of cum."

That thought surprised her for an instant, but then she realized that 
she would, indeed, be with Alex for a long time.


That night, Alex climbed into the bed he shared with Colleen and 
Thomas. Colleen always slept in the middle, with her two brothers 
snuggled close, one on each side. She had a nice pair of firm, round 
breasts that were still quite small, but they were developed enough 
that her brothers enjoyed stroking and suckling them before going to 
sleep. Colleen was content to indulge them.

"So, I hear my brother's no longer a virgin," she said, softly. "Did 
you do like I told you?"

Alex looked up at Colleen and nodded with a smile without releasing her 
nipple from his mouth. Colleen absentmindedly stroked the hair on his 
head.

"Good! You shouldn't have any trouble hanging on to Andrea if you keep 
following my advice."


Alex woke up in bed alone. He groggily made his way to the kitchen 
where his father was making breakfast. His mother was seated at one end 
of the table with his 10-month-old sister, Ella, suckling on one breast 
and his 2-year-old sister, Anne, suckling on the other. His 4-year-old 
brother, Trevor, was seated next to them, impatient for his turn. 
Candice and Lauren were seated across from Trevor.

"Good morning, sleepy head," his mother greeted him. "We were wondering 
when you were going to get up."

"Where are Thomas and Colleen?" Alex asked as he took a seat at the 
table.

"Thomas is having breakfast with Stephanie's family, and Colleen is 
with Roger's family." Roger was Colleen's 12-year-old boyfriend. "You 
should invite Andrea for lunch, today. If you two are going to be 
practicing making babies with each other, I'd like to get to know her 
better."

Alex blushed. Even though sex was openly discussed--and witnessed--in 
the colony, and even though he'd talked about sex with his parents and 
older siblings numerous times, he was embarrassed to talk to his mother 
about his specific behavior with a particular girl. Nevertheless, when 
he met up with Andrea on the way to school, he made the offer.

"My mom says you can come home for lunch with me--if you want." Alex 
added that last part with a hopeful note, knowing that his mother was 
sure to comment on their relationship. He had mixed feelings when 
Andrea accepted.

By lunch time, Alex was looking forward to bringing Andrea home. He had 
had an erection most of the morning thinking about what they had done 
yesterday afternoon, and he was hoping the two of them could sneak off 
somewhere to do it again.

As it turned out, sneaking around wasn't necessary. After greeting 
Andrea, Alex's mother announced--plainly and to the point--"Lunch will 
be ready in a little bit. If you two want to run off to Alex's bedroom 
and fool around for a while, you have time."

Alex turned bright red. He was used to his parents openly discussing 
the sexual activities of Thomas and Colleen, but it was somehow 
different when it was about him; however, he was too horny to let it 
bother him much.

In his bedroom, Andrea wasted no time spreading her legs for Alex. "Put 
it in me now! I can't wait any more. I've been playing with myself all 
morning in class. My friends were making fun of me."

Alex positioned himself above Andrea and was surprised when his penis 
easily slid into her on his first attempt to mount her. Her vagina 
seemed a lot warmer and wetter than it had been yesterday. He tried to 
control his pace to make himself last, but Andrea kept urging him to go 
faster and harder. After only two minutes, he finished with a 
satisfying series of grunts.

In between gasps, Andrea joked, "Are you sure you've never done this 
with another girl, before? You're really good at it!"

Alex gave her an embarrassed smile, then shut her up by pressing his 
lips to hers and forcing his tongue into her mouth. The two young 
lovers tongue-wrestled for several minutes before they were interrupted 
by Alex's mother.

"Andrea, give Alex a chance to recover! Lunch is ready."

Andrea laughed, but Alex scowled at his mother. A boy should have some 
privacy his first few times.

His mother was happy Alex and Andrea were together. Her adorable son 
was sure to give her many grandchildren--and more than a few of them 
would be by this stunning nymph.

Midway through lunch, Peter showed up. He was a fit, handsome man in 
his mid-twenties who was a friend of Alex's mother and visited 
frequently. Alex was fond of him and jumped up from the table to greet 
him with a hug.

From her seat at the table, Andrea waved, and said, "Hey, Peter!"

"Hi, Andrea. What are you doing here?" Peter looked at Alex then back 
to Andrea. "Oh! I see. Good choice!"

Andrea smiled. Alex looked confused.

"Alex, I put Ella down for her nap. You and Andrea do me a favor by 
minding Anne and Trevor for me. You don't have to be back at school for 
a while, yet."

"Okay, Mom!"

With that, Alex's mother disappeared into her bedroom with Peter.

"How do you know Peter?" Alex asked Andrea, suspiciously.

"Oh, he's friends with my mom, too."

After cleaning her up a bit, Andrea took Anne out of her highchair and 
placed her on the floor to play with her while Alex helped Trevor wash 
his face and hands at the kitchen sink. He then cleared the table in 
silence, pondering the new information he had acquired. When he was 
done cleaning up, he joined Andrea and Anne on the floor.

"Do your mom and Peter..." Alex talked openly about sex all the time. 
He couldn't understand why it had recently become so difficult.

Andrea waited for Alex to finish, then quickly realized that he wasn't 
going to.

"Have sex?"

Alex blushed.

"Yeah. Why?"

Alex shrugged.

"You didn't think your mom was the only one, did you?"

"No!" Alex lied. Actually, he hadn't ever really thought about it, so 
he didn't really know.

"Mom says he's really good," then, not quite so loudly and with a 
devious smile, she added, "But I bet he's not as good as you!"

Alex laughed.

Suddenly serious, Andrea pondered, "I wonder if I should find out? It'd 
be an interesting comparison."

Alex scowled, and Andrea broke out in laughter while accepting another 
block from Trevor, who was fetching them one at a time and delivering 
them to her. She added the block to the tower she had started.

"I'm just teasing! He's way too old! But I heard Kirk in Mr. Martin's 
class is a lot of fun..."

Alex gave Andrea the dirtiest look he could muster. He did not like 
Kirk.

Andrea laughed at Alex's response. "Just teasing, again! But you know 
I'll probably to it with another boy, eventually." Then she added, 
quickly, "You'll do it with other girls, too."

"Yeah, I know, but just don't let it be Kirk."

Andrea crawled over to where Alex was seated on the floor and gave him 
a hug.

"I know you don't like Kirk--that's why I said his name. I don't like 
Kirk, either. Don't worry. I'm very happy with just you, right now."

Andrea gave Alex a gentle kiss on the lips, but both Anne and Trevor 
interrupted, demanding attention, before they could go any further.

"You know," Andrea said, earnestly, "Anne looks like my little brother 
Russell. I wonder if they're siblings?"

"Silly! Anne's my sister and Russell's your brother. How could they be 
siblings?"

Unperturbed, Andrea argued, "Maybe Peter's their daddy, so maybe 
they're half-siblings."

"Wade's our daddy!" Alex felt strange referring to his father by his 
first name. He almost never did--and he couldn't recall ever calling 
his mother "Jean."

"I mean father: Maybe Peter got your mom pregnant with Anne and my mom 
pregnant with Julian."

At that moment, Peter and Jean emerged from the bedroom. Peter kissed 
her goodbye, then gave both Andrea's and Alex's hair an affectionate 
tousle before leaving. Alex considered his mother's body.

She was completely naked, as was her habit when she was home. There was 
always one child or another making demands of her breasts, so she 
almost never whore a top anywhere. Away from home, she usually wore a 
light, flowing skirt, but at home, she didn't bother.

Like all boys, Alex had always thought his mother was "pretty," but for 
the first time, he saw her as beautiful. He now knew why his 
father--and Peter--were attracted to her.

As his eyes scanned down her body, Alex noticed the glob of thick, 
white fluid leaking from between her labia. Stephanie's comment from 
yesterday entered his mind:  "A pussy full of cum." There were a lot of 
things he had known for a long time, but they were just now beginning 
to come together.


After school, Andrea's parents insisted that Alex join their family for 
dinner. Alex was dizzy from the pace at which things were changing. 
Yesterday, he hadn't ever had his penis in a girl's vagina; today, he 
was having his girl friend for lunch and dining with her family just 
like Thomas and Colleen did--and, both his parents and hers were 
teasing them about their new relationship. How'd they find out so 
quickly, anyway?

Like his own mother had done, Andrea's mother suggested they go off to 
her bedroom for "a little pre-dinner entertainment." That phrase even 
earned Andrea's displeasure. But still, there was no way either of them 
were going to spurn the suggestion.

This time, Andrea wasn't in such a hurry, so Alex took his time to do a 
good job on her with his tongue. He found that the sounds he elicited 
from her both amused and excited him.

He also decided to try something new. While tonguing her clitoris, he 
inserted a finger into her vagina.  Andrea gasped and clamped down on 
the finger. When she relaxed a little, Alex tried two fingers. Her 
vagina began tugging on them like it was trying to draw them deeper 
into her body, which was starting to writhe with pleasure. Once again, 
Colleen had given him good advice.

It wasn't long before Andrea's vagina clamped down hard on his fingers, 
and she sat up with an incredibly intense groan. What happened next 
caught Alex completely by surprise.

Andrea put her hands on Alex's shoulders and shoved him off her. As she 
did, she rolled him onto his back next to where she had been lying just 
a moment ago. She rolled with him, ending up on top. In a swift 
movement, she grabbed his very stiff penis, guided it into her sopping 
wet vagina, then began to ride him like a crazed animal. With her hands 
still on his shoulders, pinning him to the bed, she bounced up and down 
on him with determined force.

A few times, she drew up enough that Alex's penis slipped from her. 
Each time, she emitted a cry of distress before pausing, reaching 
between them, and slipping it back in. The interruptions were just 
enough to keep Alex from going over the edge. Desperate to cum, he 
began to thrust his hips up to meet hers.

Finally, Andrea's vagina tugged hard on Alex's penis, which began 
pulsing and bucking. When it began to soften, Andrea rolled off him, 
sprawling herself across the bed.

"Wow!" She gasped! "If I had known it was going to be this good, I 
would have started sooner!"

Alex rolled onto his side and smiled at her, thinking the same thing, 
himself.

At that moment, an eight-year-old girl flung open the door, marched 
into the room, and hopped up on the bed, kneeling on it just at the 
foot.

"Wow! You two are noisy!"

"Marta! You're supposed to leave us alone! Mom said!"

"Alright, alright! I thought you were done! Besides, I was hoping I 
could give Alex a try, myself."

"You're too young! You're only eight! And he's mine!"

"You're not going to share with your little sister?" Marta gave Andrea 
a sad, puppy-dog look, but Andrea was having none of it. Marta hated 
being called "little sister," and she only used the term, herself, when 
it was to her advantage.

Alex sat up and grabbed Marta's ankles, pulling her onto her back and 
towards the middle of the bed. Marta was about to protest until she 
felt Alex's tongue push between her labia. "Oh!" was all she got out.

Andrea gave Alex a good swat on the butt.

"Hey! You're not supposed to be doing that with her! She's too young."

Alex gave Marta's clitoris a few good licks, then paused and turned to 
Andrea.

"I do this for my little sisters Candice and Lauren all the time--and 
Candice is 8, and Lauren's only 7."

Alex put his tongue back to work--much to Marta's approval.

"But you're my boyfriend!"

Alex got a few more gasps from Marta before taking a break to answer 
Andrea.

"Haven't you taught Jake to do this?" Jake was Andrea's brother.

"He's only seven!"

"I was only seven when Colleen taught me!"

He returned to Marta, who was grunting her disapproval at him for 
having stopped.

Andrea rolled over and hugged Alex's back, looking over his shoulder to 
get a close-up view of what--exactly--he was doing to cause the noises 
Marta was making. Mom was right: the girls in their family were a noisy 
bunch!

"Stop! I'm gonna pee!"

Alex had no intention of stopping, but he started laughing so hard that 
he had to. Much to his astonishment, a few drops of pee squirted from 
Marta. She cupped her hand between her legs, then scrambled off to the 
bathroom.

"No one's ever done that, before!" Alex exclaimed, causing Andrea to 
laugh.

Marta was very quiet during dinner, but just before Alex left, she 
pulled him aside and whispered in his ear, "Thank you!"


The next day, Alex again woke up in bed alone. He didn't like that. 
Usually, Colleen or Thomas would kiss him gently on the lips and 
whisper in his ear. He stumbled into the kitchen, surprised to find it 
empty. Ella was in her play pen in the livingroom. Anne and Trevor were 
playing beside her.

"So, you're finally up! Andrea must have really worn you out, last 
night."

Alex turned around to see his mother coming out of the bedroom that 
Trevor shared with Candice and Lauren. He wondered how long the teasing 
was going to last. He didn't remember his parents doing this to Thomas 
and Colleen. Oh, wait: He did. He also remembered how fun it was to 
join in. Being on the receiving end wasn't so fun.

Alex was suddenly awake. He looked for any sign of Candice or Lauren.

"Am I late for school?"

"You're not going to school, today. Did you forget? Your dad's taking 
you to The Park."

"The Park" was a project that had been going on for quite some 
time--and had been in the planning stages even longer.

Mars Colony exists largely underground. Rather than mining building 
materials and constructing buildings on the surface, it's far easier 
just to tunnel out the subterranean rock. Laser drilling rigs make 
quick work of it.

The colony consists of a large number of "nodes," connected to each 
other by long, narrow tunnels. Usually, there are two tunnels: a larger 
one for transportation, and a smaller, parallel maintenance/emergency 
shaft, which is also used for atmosphere management. Air is pumped 
through greenhouse nodes to remove carbon dioxide, so the tunnels 
provide for the movement of air as well as colonists and supplies.

It's a very practical arrangement, but it can be a bit dull--like 
living in a cave, which is essentially the fact.

The Park, as it is simply known, is a crater over which a transparent 
dome had been constructed. When finished, it will be pressurized and 
filled with plants, trees, and even real grass. They'll be a lake for 
swimming and other features to replicate--as closely as is possible on 
Mars--an actual park on Earth.

Alex's father is an atmosphere and environment technician. He works on 
The Park as time allows--when there aren't more pressing needs, which 
there usually are. The same is true for everyone, so progress is in 
fits and starts.

One time, when the work wasn't dangerous and didn't require pressure 
suits, Wade took Thomas to work with him. Another time, Colleen got to 
go. Alex had been anxious for his turn, but it had been long in coming.

Jean smiled at her son's stiff penis. She loved the way little boys got 
stiff when they were excited about anything--not just sex. She also 
loved that Alex had the cutest penis she had ever seen on any boy.

Jean ushered Alex to the couch. She sat down, drawing him into her lap 
and offering him a breast. She loved suckling her children; it was one 
of the most pleasurable parts of being a mother. Of course, Ella and 
Anne were suckling regularly, and Trevor was still suckling three or 
four times a day. Candice and Lauren were down to mostly just once, 
before bed. This left little time for her three oldest children, so it 
was extra special when she could indulge them.

Alex sucked greedily. It had been a long time since he had suckled his 
mother's breast; he truly missed it. Suckling Colleen's breasts was 
nice, but hers didn't make milk.

As Alex suckled, Jean fondled his small testicles. She then wrapped her 
hand loosely around his penis and stroked it very slowly, taking two or 
three seconds going down and another two or three seconds coming back 
up. Alex squirmed. The pace was too slow for him and the contact too 
light, so he began pushing his hips up to meet his mother's hand. 
Whenever he did so, Jean released his penis. When he'd stopped 
squirming, she'd continued stroking him at that same measured pace. She 
always did this when she suckled Alex. It was easy to get him to the 
edge and keep him there.

It was now taking only a few strokes to edge him. She'd give him a 
ten-second break, then a few more strokes. He was whimpering as he 
switched breasts while turning his body so that he was straddling his 
mother's legs, rather than lying across her lap. Jean knew this trick: 
it would allow Alex to thrust against her belly and make it more 
difficult to control his stimulation.

"There's a better place for that."

Alex released his mother's nipple, sat back slightly, and gave her a 
questioning look. A little milk dribbled down his chin.

In answer, Jean turned herself and lay back on the couch. Alex 
understood immediately. The repeated edgings blocked any doubts he 
might have had. Instead, he slipped his aching penis straight into his 
mother's dripping vagina.

It felt very different from Andrea's. It was much looser and didn't 
grip his penis the way Andrea's vagina did. Still, it felt wonderful, 
and Alex humped furiously, relieving himself a mere fifteen seconds 
after mounting his mother. Once his penis had softened and slipped out 
of her, he crawled up her body a little and resumed suckling her breast.

Alex's father actually showed up before lunch.

"Let's go, bare cub! We're on the next surface shuttle to Argos. We'll 
be there in time for lunch, so I thought you might want to eat there."

Alex beamed with excitement. He had never traveled in a surface shuttle 
before. His limited travel had always been on the sub-shuttles that ran 
in the tunnels. Actually, most of it had been on foot.

On short hauls, the shuttles only required one pilot, so Wade had 
arranged for his son to sit in the co-pilot's seat.

Alex had mostly just seen pictures of the surface of Mars. Observation 
domes dotted Mars Colony, but the view was limited. Even at the low 
altitude of the surface shuttle, Alex could see far off into the 
distance. His eyes drunk in the beauty and wonder of the planet he 
called home. He was just realizing how little of it he knew.

After giving Alex time to enjoy the scenery, the pilot explained the 
controls to him, and even allowed him to "fly" the craft for a while. 
The whole trip took 30 minutes, but to Alex, it seemed like it was over 
as soon as it had begun.

Wade met Alex at the docking port after all the other passengers had 
disembarked. He was going to ask Alex what he thought of the flight, 
but there was no need: Alex chattered non-stop all the way to the 
cafeteria, giving his father a big hug when they arrived.

The cafeteria was like any other cafeteria: putting it on Mars did 
nothing to improve the quality. Like most cafeterias, the food was 
nutritious, bland, and edible--but only just; however, Alex thought it 
was the best food he had ever eaten, which says more for the ambience 
than the cooking.

"Just so you know," Wade told Alex, "You're not getting all this for 
free: I'm going to put you to work."

"That's fine with me!"

Wade smiled. Putting children "to work" was the best thing a parent 
could do for them. Children were eager to help contribute to the 
family--if only allowed. It gave them a sense of worth. Too much idle 
play created miserable brats.

"You'll be replacing control modules in a series of atmospheric 
monitors. Turns out that the ones they were delivered with have some 
bad components, so you're going to replace them with new modules, and 
we'll send the old ones back for refurbishing. The new cards have a 
blue dot on them. Mark the old ones with a yellow dot *before* you 
remove them: We don't want to mix them up."

Wade needn't worry about trusting such an important piece of equipment 
to a 10-year-old boy. Not that the units wouldn't be tested before 
being put into production, but the modules were of the kind that were 
ubiquitous on Mars Colony. Children played with them in school. Any 
8-year-old Martian could handle the task. Children grow up learning 
what they need to survive, and any Martian over the age of seven knew 
the importance of doing careful work when it mattered.

Wade watched the first two to make sure that Alex was doing it right, 
then left him on his own. When he returned, Alex was surprised to learn 
that two hours had passed.

"I still have more to do!"

"And they'll still be there after we take a break. It's not good to 
work too long at one task without taking a break: You get sloppy."

"I won't get sloppy!"

"Of course, not! Because you're going to take a break with me."

In the cafeteria, Alex met John. John was his father's age, and the two 
men had been friends since before Thomas was born, but their jobs had 
mostly kept them apart for the past five years.

"This is Alex? This can't be Alex! He was just a little tunnel rat when 
I saw him last."

Alex smiled at the disparaging term that was directed at him. He rather 
liked the idea of being a tunnel rat--though he'd never admit it.

"He's quite a looker," John continued. "Is he ravishing the girls, yet, 
or is he still playing five on one?"

Alex blushed. Why was this all suddenly so embarrassing?

"Actually," Wade explained--much to Alex's exasperation, "He just 
caught his first little lassie the other day: a really cute blond."

"Gimme five, Alex!" John said cheerily, raising his hand. Alex did not 
give him five.

"He's still in that 'sudden awareness' phase," Wade explained, "It 
really bugs him when anyone talks about it--so, of course, we've all 
been talking about it incessantly."

"Well, kids are starting earlier than you or I did, back when, which is 
too bad: I wouldn't mind going a round or two with him before he gets 
set on girls. You still owe me one for that night in Campos."

"Campos!" Wade said, cognizant of John's meaning. "Where does the time 
go?"

Alex spent another two hours working on replacing the modules before it 
was time for dinner.

"Are we gonna take the surface shuttle back, tonight?" Alex asked his 
father, hopefully.

"Unfortunately, no. We'll be taking the sub-shuttle back, but we're not 
going, tonight." Alex's disappointment was banished by a sudden, new 
excitement. "We have more work to do, tomorrow. We'll go back in the 
late afternoon."

Wade was quiet for a moment before saying, "I have some pressure-suit 
work to do this evening, so I'm going to leave you with John. Do you 
think you can handle that?" The question was directed at himself as 
much as it was toward his son.

Alex knew better than to ask to go along, but it didn't matter: the 
excitement of spending the night here and doing more work in the 
morning was more than he had expected.

"Sure!"

"You do what he says, now. Understand?"

"I'll be good!" Alex said, surprised that his father would question his 
behavior. Alex never had any interest in misbehaving. He didn't see the 
attraction.

"That's not what I mean. Anyway, you'll be fine. Hear?"

John met Alex in the cafeteria and took him back to a small bachelor 
apartment. It had three rooms: a combination kitchen/dining room/living 
room, a bedroom (which was not much more than an enclosed bunk), and a 
bathroom that crammed a sink, toilet, and shower all on the same 
flooring. Alex thought it was amazing.

John sat down on the padded lounge chair and waited patiently for Alex 
to thoroughly explore the small space. When he had finished, John 
pulled him into his lap, hugging him close to his body with Alex's bare 
back pressed against his own bare chest. Alex's skin was incredibly 
soft, and John enjoyed rubbing his hairless chest and belly. The small 
expression of affection stiffened Alex's little penis, and he relaxed 
and breathed a sigh of contentment.

While John's one hand roamed Alex's chest and belly, the other strayed 
to his thigh, first the top and outside, then to the inside. Alex 
relaxed further, so John slid his hand over Alex's tiny jewels, lightly 
grasped his penis, and gave it a few long, slow strokes. Alex purred, 
squirming a little bit before settling back down.

John continued the long, slow strokes and began fondling Alex's 
testicles with the fingers of his other hand. Alex's scrotum was thin 
and loose, distinctly displaying the two small testicles that were held 
close to his body. Alex pushed up towards John's hand, sliding a little 
down his lap in the process.

With the hand that had been working Alex's penis, John reached under 
Alex, catching his butt to stop him from sliding off his lap. He 
pressed his middle finger against the boy's rosebud. Alex flinched and 
began squirming as John tried to work his finger inside.

Alex rolled over and slid down John's legs, ending up squatting on the 
floor at John's feet.

"Hey! That tickles!" Alex tried to sound mad, but it was clear that he 
wasn't.

John leaned forward, wrapped his arms around Alex's chest and waist, 
then stood up, lifting Alex off the floor as he did. Next, he tossed 
Alex into the chair so that he was kneeling on the seat with his hands 
against the backrest. With an arm firmly around Alex's waist, he again 
probed his hole with a finger. Alex giggled and squirmed.

"Hey! You're not supposed to do that!" The giggling belied the 
seriousness of the statement.

John removed his finger. Without letting go of Alex's waist, he reached 
over to the small stand next to the chair, opened the drawer, and 
removed a small jar. He deftly worked the lid off with one hand, 
scooped out a good portion of it's contents, and pushed it into Alex's 
rectum. Alex squirmed even more at the cold, wet sensation.

"Hey!" This time, there was no giggling and just a little sound of 
worry in his voice.

John dropped his shorts and coated his erection with more of the 
lubricant before placing the tip of his penis against Alex's hole. Alex 
jumped, but he couldn't escape John's grip on his waist. John pushed 
slightly, and Alex cried a nervous, "Ohhhhhhhh!"

Alex took a few hard breaths, then realized that John's penis was 
inside his butt. He trembled, slightly, then jumped again when John 
pushed in a little further. John held still there, allowing the boy to 
become accustomed to his presence.

Alex thought, "Oh! This is just what Thomas used to do with me!" He 
relaxed a little at the realization. Before Stephanie had become his 
girlfriend, when he was ten and Alex eight, Thomas had explained to 
Alex a game that boys could play together. They had played it, from 
time to time, until Thomas had started mating with Stephanie. John's 
penis was a lot bigger than Thomas' had been, but it wasn't too 
bad--now that Alex was getting used to it.

He took a deep breath, relaxed himself a little, then pushed his butt 
toward John. He felt himself stretch, but it only hurt a little. Like 
it had with Thomas, he knew he'd get used to it.

John released his grip on Alex's waist, then put his hands on Alex's 
hips. He pulled back about an inch, then pushed forward. He could tell 
it was a little uncomfortable for Alex, but the boy didn't complain. 
John slowly worked himself in and out, not needing to go any deeper 
than he already had. There was no need to risk injuring the boy.

Alex tried to keep his sphincter relaxed as John worked his penis back 
and forth. The pain was mostly gone, now, and it was actually starting 
to feel a little good. He knew how happy this had made Thomas, and he 
was feeling good, now, about making John happy, too.

John tried to make himself last, but the boy's tight hole was just so 
incredibly stimulating that he only managed five minutes before 
releasing his load into Alex's bowels. He fought the urge to bury his 
cock in him. He held himself inside Alex until his penis softened and 
Alex's tight hole squeezed him out. Alex turned to sit on the chair, 
but John stopped him, indicating that he should kneel in front of him.

John retrieved a wet nap from the drawer and handed it to Alex. "Clean 
yourself."

Alex moved into a squat and wiped the slimy mess from between his 
buttocks. John handed him another wet nap. "Now, clean me."

Alex balked, but John gave him a stern look, so he wiped the other 
slimy mess from John soft penis.

"Is it clean?"

Alex nodded.

"So put it in your mouth and give it a good suck."

Alex balked, again.

"If it's clean, that shouldn't be a problem."

Alex took the hint, and did a more thorough job of cleaning John's 
penis. John still made him suck on it to prove that it was clean.

Alex slept with John spooning him from behind. Some time in the middle 
of the night, John woke him for a second round. Round three was in the 
shower before breakfast.

John was an even better cook than his father--and Alex was famished--so 
he didn't mind not eating breakfast in the cafeteria.

When Alex met his father, Wade noticed Alex's tell-tale walk.

"You okay?"

"Sure!"

"Really?"

"Yeah, Dad. I'm fine. What are we doing, today?"

Alex's cheery disposition convinced Wade that his son really was fine. 

"We have to pull cable for the monitoring systems. We can do that 
together."

Alex smiled. He loved working with his father.


On the sub-shuttle ride back home that afternoon, Alex sat in his 
father's lap--slouched, actually. His legs were spread, his feet were 
dangling, and his father's arms were wrapped around his chest. He was a 
content boy.

Absentmindedly, he considered the girl sitting across from him. She was 
his age, and she was seated in her mother's lap similarly to how he 
was, with her legs spread, only she was sitting upright, rather than 
slouching.

After a while, he noticed she was smiling at him: he had been caught 
checking her out! Strangely, he wasn't embarrassed, and he didn't look 
away.

The girl lowered her eyes, then looked back up at Alex. He didn't get 
it, at first, but when she did it again, he looked down and noticed 
that his penis was sticking straight up. Again, rather than being 
embarrassed, he casually reached between his legs, adjusted his 
testicles, then gave his penis a single stroke before putting his hand 
back on his thigh. The girl's smile widened.

She placed a hand on her belly, then slowly moved it down over her 
labia, then slowly back up. This time, Alex's smile widened. He tensed 
his pubic muscles, causing his penis to jump. The girl smiled, then 
lower her hand back over her labia and spread them apart, showing Alex 
her gaping vagina. The girl's mother gave her daughter a smart swat on 
the butt. The girl jerked her hand away. She sat up just a little bit 
straighter, but left her legs spread.

Alex looked away, this time a little embarrassed at having been caught 
by the girl's mother. When he looked back, the girl was still smiling 
at him.

The girl and her mother got off the sub-shuttle with Alex and his 
father. The mother was holding her daughter's hand when she caught 
Wade's attention.

"Looks like your son and my daughter are interested in each other."

Wade had witnessed the entire exchange and had done everything he could 
to keep from laughing. Now, he allowed himself a chuckle.

"Yes, well, they're at that age, I guess."

"We live just a short walk from here. We could let them have a play 
date. It'd be a shame to leave them frustrated."

"I'm not sure Alex would be interested. He's sort of hung on his first 
girl. It's only been a few days."

Alex didn't like being talked about like he wasn't there--especially 
when the talk was about sex. He wrapped both his arms around his 
father's left arm, then leaned into him with a very soft growl.

The woman continued her proposal. "Well, maybe you and I could set an 
example, and we could just leave our kids to do as they please. Your 
boy's really cute; I wouldn't mind having one like him."

Suddenly, Alex realized what the woman was suggesting. He knew his 
mother had sex with Peter, but his father had never brought another 
woman home. Of course, he knew that didn't mean that his father didn't 
visit someone else. He wasn't at all sure about this--and he had no 
idea what his mother would think of it--but a few minutes later he 
found himself alone with the girl in her bedroom.

"It's pretty cool, huh? Your dad and my mom in the room next to ours?" 
Jennifer snuggled up to Alex. "I've only ever done it with three other 
boys. How many girls have you been with?"

"Only three?" Alex thought to himself. "Only?" He thought of Andrea and 
how she had told him--just two days ago--that she was happy with just 
him. Right now. That "right now" part nagged at him. His train of 
thought was interrupted when Jennifer bent over and took his limp penis 
into her mouth. It began to stiffen immediately.

As soon as it was fully stiff, Jennifer sat up and straddled Alex's 
legs, then lowered herself onto him without asking if that's what he 
wanted. Alex immediately realized that it was what he wanted. He'd 
worry about Andrea, later.

Alex relaxed and let Jennifer do the work. Her rhythm and pace were 
different from Andrea's--not better, not worse, just different. He 
luxuriated in the slow, easy pace. His orgasm caught him by surprise.

"Mmm! That was nice!" Jennifer cooed.

They laid next to each other for a while, softly stroking each other's 
hair, face, and chest. They were interrupted by Wade's call.

Jennifer's mother was naked. Alex saw his father's semen oozing down 
her left thigh.

Alex was quiet for the first few minutes of the walk home, then 
curiosity overcame his contemplation.

"Dad? Is Peter Anne's father?"

Wade chuckled. "What brought that on?"

"The other day, Andrea said Anne looks like her brother Russell. I know 
Mom has sex with Peter. Andrea says Peter has sex with her mom, too."

"Yes, Peter is Anne's father. He's Ella's father, too, and I wouldn't 
be surprised if your mother's belly starts to bulge some time in the 
next few months."

"Are you going to make a baby with Jennifer's mother?"

"She wants me to. I'm sure gonna try!"

"Are you my father?"

"Yes--and Thomas' and Colleen's, too."

"What about Candice, Lauren, and Trevor."

"No, they were fathered by another man. I don't think you ever met him. 
His name was Stuart."

"Oh."

"Are you feeling bad about having sex with Jennifer? Andrea will 
understand. I wouldn't be surprised if she has something to tell you 
when you see her next."

"What do you know?"

"Nothing in particular, but just like you were curious to see what it 
was like with another girl, I'm sure Andrea is curious to see what it's 
like with another boy. I wouldn't worry, though: Andrea's not going to 
give you up. I'm certain of that!"

Alex didn't like this subject.

"Do you have other children?"

"You mean besides those living with your mother? Yes, and it looks like 
I'm going to have a few more. When I go to visit Lisa, again--that's 
Jennifer's mother--you should come along. I'm sure Jennifer wants to 
see you, again, too."

Alex fell asleep, that night, pondering the implications of regularly 
seeing both Andrea and Jennifer. Jennifer was fun, but Alex didn't want 
to do anything to upset Andrea.


Alex was dreaming about Andrea. She had her face close to his and was 
whispering something that he couldn't quite make out. She leaned in and 
kissed him gently on the lips, then repeated her whisper. Alex still 
just couldn't understand what she was saying. She leaned in, again, for 
another gentle kiss. This time, Alex heard, "It's time to wake up."

Alex woke up and was not surprised to see a face in front of him. He 
was surprised that it was Colleen's. She kissed him gently on the lips, 
then sat up and said, "I hope you got a good night's sleep because 
we're taking a trip. Mom has breakfast ready."

Alex's penis was stiff, and Colleen was sitting on it so that it was 
nestled between her labia. Alex briefly wondered what it would be like 
to slip his penis into his sister's vagina, but Colleen hopped up and 
left the room before he could consider it further.

Colleen had joined Thomas at the table, but their other siblings were 
nowhere to be seen. Alex realized that it must be very early. His 
mother put a plate for him next to Thomas, and Alex sat down.

"Where are we going?"

"It's a surprise," Colleen answered, "But Thomas and Stephanie and 
Roger and I are taking you and Andrea somewhere special, so eat, use 
the facilities, and grab your pressure suit."

Alex perked up at the mention of pressure suits, but he couldn't get 
any more information out of Colleen, Thomas, or his mother.

Alex's pressure suit fit in a backpack that he could comfortably hang 
from his shoulders. He had seen pictures of the suits the explorers on 
Mars had worn. They were bulky, but the suits worn by the first men to 
walk on Earth's moon were even bulkier. Alex wondered how they were 
able to even move, much less get any useful work done. Of course, 
Alex's suit wasn't rated for the vacuum of space, but it was more than 
adequate for the thin atmosphere of Mars.

Everyone on Mars Colony had their own pressure suit. His father had one 
tailored to fit him perfectly; Alex's was a child's suit designed to be 
adjustable so that it would last at least through small growth periods. 
He had inherited it from Thomas after his brother had recently added 
three inches in just a few months.

He exited his bedroom just in time to meet Stephanie, Roger, and Andrea 
at the door. The six of them caught the early sub-shuttle for the 
15-minute ride to Primos.

Alex suited up in the ready room with the others. It had been a long 
time since he had been out on the surface--maybe even before Ella had 
been born--but he, like all Martians, regularly checked out the suit, 
so he was well-practiced in putting in on.

First came a mesh undergarment with tubing for circulating water to 
control body temperature. It was basically of the same design that had 
been used on the first Lunar suit. Even though it was a fairly open 
mesh, it felt strange against Alex's skin: he spent so much time naked 
that any clothing at all felt strange.

The suit, itself, was made of a thin, strong, light-weight material. 
There were straps that tied to meshing so that the suit could be 
adjusted to fit reasonably well without bulging. There was a single 
zipper in the front that extended from neck to belly. The boots and 
gloves were removable so that they could be sized to the wearer, but 
Alex always left them in place, so all he had to do was step into the 
suit and zip it up.

"Hold on, little brother!" It was Colleen. "Where are you racing off 
to?"

Alex resented being called "little brother"--a fact he conveyed with 
his tone of voice.

"I can do it!"

He was constantly reminding Colleen that she was only a year older than 
he was, and she was constantly reminding him that 11 in girl years was 
much older than 10 in boy years; their parents were constantly 
reminding both of them that they loved each other--which made Alex gag 
and Colleen smile.

"I know you can do it. I also know that you know someone else always 
has to check it. Thomas checked mine, and I checked Roger's. Now, I'm 
going to check yours."

Alex was a little embarrassed that he had gotten upset with Colleen. It 
was a silly mistake. He had a girlfriend, now; he shouldn't be making 
little-kid mistakes like that. She let him inspect the coupling between 
the mesh undergarment plumbing and the hoses in the suit--and he didn't 
protest when she made the rest of the checks.

The controls were mounted in a small box on the chest, and the small 
oxygen bottles were mounted on the back. The arrangement of the 
connections and controls made it possible to suit up on one's own--if 
necessary--but you always had someone else check everything for you.

Soon, the six children were out the airlock and on their way to one of 
the first habitats built on Mars.

They couldn't see their destination from where they were currently, 
which was in a narrow passage through some rocks. Colleen knew the way 
very well, but she still projected their planned route onto the inside 
of her helmet's visor. She was leading the way, and she trusted Thomas 
to bring up the rear, making sure that Alex and Andrea didn't stray or 
otherwise get into trouble.

Alex was thrilled to be out on the surface, but he was a little 
disappointed that the view wasn't as impressive as what he had 
experienced in the surface shuttle--until they came out of the passage.

The plain in front of them was flat, strewn with small rocks, and 
extended to the horizon. Alex saw the dusty white cylinders that were 
their destination, but he couldn't judge how far away they were. 
Spending most of his time in the tunnels left him without a good eye 
for distance.

After about 15 minutes of walking, they reached the habitat. There 
wasn't much to it. It had been constructed from rocket stages adapted 
to the task. Alex couldn't believe the first travelers to Mars had 
spent almost a year living in the tiny structures.

The fuel cells had long-ago been spent, and the batteries had been 
removed, but the airlock was mechanical, and Colleen insisted that they 
use it as was intended, which meant they could only enter two at a 
time--and they had to wait for the airlock to "cycle," even though 
there was no power for the pumps and no air even if there were.

The inside was cramped for six children. Alex wondered how many adults 
had lived here.

Each module was designed for a different purpose--airlock, sleeping 
quarters, common area, scientific experiments--and the modules were 
joined through air-tight doors that weren't locks.

Colleen wished there was power and air so they could take off their 
suits, but the lack of power did have one advantage: she could operate 
all the controls without having to worry about what would happen.

Colleen and Roger explained everything to the others. They both knew 
just about everything there was to know about the habitat. That was one 
of the reasons Colleen liked Roger: he was as into old space gear as 
she was.

Colleen was pleased to see that Alex was enthralled by the habitat. She 
felt at home in a pressure suit, but the one thing she disliked was 
that she could have no real contact with another person. She was used 
to touching her brother: running her fingers through his hair, rubbing 
his shoulders and neck, patting his buttocks, running her bare feet up 
and down his legs under the table during meals. She craved physical 
contact; a hug in a pressure suit was no hug at all. Still, it pleased 
her to think that his little penis would be stiff inside his suit: boys 
his age got stiff from any excitement.

Colleen didn't need the warning light to remind her how much air she 
had left, but she had set it anyway. She was pleased with herself when 
she automatically checked the reading a few seconds before the reminder 
lit up.

"I'm at 75%. What do the rest of you have?"

Each of the other children sounded off, and Colleen was again pleased 
that she and Roger had done the best at conserving their consumables.

"We better start back."

Children unaccompanied by an adult were required to return from any 
outside excursions with at least a 50% margin on consumables. Colleen 
wanted to be well within that limit. Going over meant an immediate call 
to all parents, which would result in a tanning from her father for 
being careless, and a further tanning from her mother for being 
careless with Alex and Andrea in tow. As the oldest, Thomas would catch 
the worst of it.

However, Colleen wasn't concerned about the consequences: She insisted 
on getting back on time because that was the right way to do it. She 
wanted to be an explorer--maybe even an astronaut--and she took 
anything even remotely related with all seriousness.

The children took their time getting back--with Thomas in front, this 
time, and Colleen taking up the rear. Still, they returned with plenty 
of margin to spare.

Colleen removed a small item from a pouch on her thigh and used some of 
her air to inflate it. It was a serviceable soccer ball for the surface 
of Mars. The children played for a while just outside the airlock until 
Colleen signaled that they should head in.

They vacuumed the dust from their suits before removing them and 
carefully packing them away--after fully charging the oxygen bottles 
and double-checking each other.

Colleen's friend Martin was managing the lock, today. He and the 
children were the only ones there. Colleen couldn't understand why more 
people weren't interested in going outside, but she did love having the 
surface to herself (well, and her companions).

When everything was packed away, Martin called to Colleen.

"You can leave your packs on the bench, there. I'll keep an eye on 
them." (Not that anyone would bother them--even if anyone had been 
there.) "I suppose you're on your way to the observation lounge? I'll 
mark it under maintenance so you can have it to yourselves."

One of the reasons Colleen had chosen today to take Alex and Andrea out 
on the surface was because she knew Martin would be working.

The children climbed the stairs up to the observation lounge. It was 
transparent from the floor on one side, through the ceiling, to the 
floor on the other side. It was raised above the airlock and ready room 
high enough to afford a view over the neighboring rock.

Alex and Andrea were holding hands, gawking at the scenery. Colleen 
stood behind them, with one hand on Alex's shoulder and the other on 
Andrea's. Roger stood behind her, looking over her shoulder, with his 
hands on her hips and his limp penis nestled between her buttocks. 
Thomas and Stephanie were already making out on one of the benches.

The children enjoyed the view for while, but eventually, the noise 
Thomas and Stephanie were making became too distracting. Stephanie was 
now on top of Thomas, using her pussy to bring him repeatedly to the 
edge. From the sounds he was making, she was really torturing him.

"Alex," Colleen began gently, "Now that you're having sex, it's 
important to learn--right away--about sharing. You were the first boy 
to put his penis inside Andrea's vagina; I think you should let Roger 
be the first boy to ejaculate in Andrea's vagina."

Jealousy filled Alex's face, then he remembered what his father had 
told him--and what he had done with Jennifer. Having sex with a girl 
was part of growing up--and sharing the girls you had sex with was a 
part, too. If he wanted Colleen to stop treating him like a baby, he 
had to avoid acting like one. He was glad that Colleen was the one to 
bring up this subject: it made it easier.

Seeing that Alex was accepting the idea, Colleen turned to Andrea.

"Andrea, has a boy ever ejaculated in you?"

Andrea blushed. "I don't think so--I've only ever had Alex inside me."

"Alex hasn't started making semen, yet, so Roger would be your first. 
Would you like that?"

Andrea looked at Alex, wanting to say yes, but afraid of hurting his 
feelings.

"It's okay," Alex said. "I like Roger. I'd like it if he was your 
first."

Alex wasn't sure how much of that he believed, but he sounded 
convincing enough to get a smile from Colleen and get Roger an eager 
nod from Andrea.

Suddenly, Andrea had second thoughts. "Will Roger give me a baby? I 
want Alex to give me my first baby."

Colleen smiled. "You're not old enough to have a baby, yet, so don't 
worry about that. I'm sure you're going to give Alex many babies--when 
you do get old enough."

Andrea relaxed. Anxious to enjoy this first experience, she immediately 
laid back on one of the benches and spread her legs, inviting Roger to 
mount her.

The brief talk of making a baby had roused Roger's interest--and his 
penis, which was beginning to stiffen. He gently climbed on top of 
Andrea and gave her a warm, wet kiss on the mouth. He continued kissing 
her as he slowly worked his stiffening penis against her labia. When he 
was fully erect, he pulled his face away from Andrea's and gave her a 
questioning look. She nodded enthusiastically.

Roger pressed into Andrea slowly, but Andrea still let out a startled, 
"Oh!" Roger's penis was a little longer and thicker than Alex's, and it 
felt strange going into her.

Colleen sat a on neighboring bench with Alex in her lap and her arms 
loosely wrapped around him. She felt him tense when Roger entered 
Andrea. She gave him a reassuring hug, and he relaxed--a little.

Roger thought how lucky Alex was to have Andrea. He had been with quite 
a few girls, but after Colleen, Andrea's pussy felt the best wrapped 
around his cock. He wasn't sure what made each girl different, but 
Andrea was definitely a good catch.

After it was clear that Andrea was doing okay, Roger picked up the 
force and pace of his thrusting. Andrea responded with considerable 
gasping and moaning, which again caused Alex to tense up. Colleen 
hugged him tightly and gently rocked him until he relaxed some.

Roger was thoroughly enjoying Andrea. He wanted to make it last, but 
his orgasm snuck up on him. He found himself pushing hard against 
Andrea as his penis spurted his semen deep into her body. Andrea cried 
out with surprise.

When they both had come down from their ecstasy, Roger blushed: He was 
experienced enough to last longer than he had, but seeing the smile on 
Andrea's face made him feel better.

As soon as Roger climbed off Andrea, Alex wanted to jump onto her. When 
Colleen felt him begin to stand, she hugged him tightly, again. She 
actually had to fight him, a little, to keep him from pouncing on 
Andrea. After he had calmed down and relaxed, she let him go. Alex 
wasted no time mounting Andrea and thrusting his penis in her vagina 
for all he was worth. He didn't even last as long as Roger.

Now that he had satisfied his jealousy, Alex--like Roger--felt 
embarrassed about how quickly he had finished with Andrea. He was also 
embarrassed about how he had behaved, but Andrea's smile soothed him as 
it had Roger.

Colleen made Alex make out with Roger until she could tell that he was 
no longer forcing it and was actually enjoying it. She wanted Alex and 
Roger to be friends.

Stephanie had finally allowed Thomas to cum about the same time as Alex 
was finishing with Andrea. Colleen was the only one of them that hadn't 
had sex, but she was satisfied with how things had gone with Roger, 
Andrea, and Alex, so she felt content. The children grabbed their packs 
and caught the next sub-shuttle back home.


Colleen had Thomas arrange to spend the night with Stephanie, and she 
got Roger and Andrea to sleepover with herself and Alex. She looked 
forward to the four of them sharing a bed--eager to build on the good 
relationship that Alex was forming with Roger.

Roger knew about Colleen's plan and was happy with it. He liked Alex 
and thought he was incredibly cute. As much as he liked girls, Roger 
still had a soft spot for younger boys, and Alex filled that spot 
particularly well.

After dinner, the older children spent time playing with Colleen and 
Alex's younger siblings, then put them to bed when it was time. Candice 
and Lauren enjoyed the attention they received from Roger, and Trevor 
was thrilled with Andrea's affections. The four older children went to 
bed early, themselves--but not to sleep.

Colleen insisted that Roger fill Andrea's pussy with cum, again. but 
this time, she didn't allow Alex to mount Andrea afterwards. Instead, 
she held Alex tightly while masturbating him. She kept edging him while 
Roger and Colleen cuddled and exchanged tender kisses with each other. 
When Roger and Andrea were ready to sleep, she at last let Alex orgasm, 
but she continued holding him, snuggling him closely, denying him 
access to Andrea. She didn't relax her hold until she was sure he was 
asleep.

Some time later, Colleen was awakened by Alex pounding his penis into 
Andrea. This time, Alex took quite a long time with it--ensuring that 
Andrea was fully satisfied before allowing himself an orgasm. Colleen 
signaled Roger--who had also been awakened by Alex's efforts--that she 
wanted him to mount her, which Roger was eager to do.

As Roger worked his penis in her vagina, Colleen thought about the 
day--hopefully not too far in the future--when she could have Roger's 
baby. She already had the beginnings of breasts, so she hoped it 
wouldn't be too much longer before she started ovulating. She thought 
how perfect it would be if she never got her period--if the very first 
egg her body released was fertilized by Roger's sperm.

That thought gave Colleen an incredible orgasm. Her spasming vagina 
pulled Roger over the edge, and Colleen enjoyed his warmth spreading 
inside her. She didn't know it, but she was getting her wish as she 
slept peacefully in Roger's arms next to her darling brother and his 
stunning girlfriend.
