Putting his hands in his pockets to try to put his unrelenting hard on in a position that didn't make riding a bike miserable, Joseph realized he had to add another problem to the long list of things that were tormenting him. He had a key to the shed, but not one to get back inside his house. He would have gladly stayed at Dana's but for the fact that her son had returned home. That left him with no option but to return to his own house, where no doubt, his mother was waiting to continue her obscene seductions. He knew he was in no condition to resist his mother tonight. He had stopped fucking Dana mid stroke, and his cock was letting him know how upset it was with him.

For one thing it was sore from all the fucking he had done this weekend. For another, it refused to get any softer, so riding a bike was just painful. Worst of all was the nagging fear that he had been having unprotected sex with his mother, off and on, for almost a week now. The though of impregnating his mother should have made his dick limp as a noodle, but it was having the absolute opposite effect. That terrible idea was just as responsible for his inability to get soft as his interrupted sex with Dana. His cock demanded release inside a woman's pussy, and Joseph couldn't get the lurid fantasy of filling his mother's cunt with cum one more time out of his head.

Muttering to himself, Joseph admitted. “I guess it doesn't matter if I have to knock on the door. Even if I had a key, that wouldn't stop me from trying to knock my slutty mother up again before I ask her if she's using some sort of birth control tonight.” Joseph tried to rationalize his uncontrollable desire with his goal of not being the kind of son who fucks his mother. “It's not my fault. If Dana's son hadn't come home, I could have finished up inside of Dana and I wouldn't need to do these horrible things to my Mommy.”

Even as he said that, it made more guilt flare up. The first few times he fucked his mother, he had been able to flee back to his room after his lust was spent, but now he knew that once he succumbed to her body he was helpless. It wasn't fair, why did every inch of his mother have to be so perfect? It felt so good to hold her in his arms, cuddling her and kissing her after sex. All that good satisfying sex he had with Dana this weekend was going to be wasted, just because her son had come home early.

Joseph's catalog of problems didn't include the fact that the woman he depended on for what he considered good sex was in the process of seducing her own son. That was probably a good thing. In his confused state, there was no telling what that knowledge might have done to him.

David sat on his mother's bed, under the covers. He was watching his mother wash her face and otherwise get ready for bed. There wouldn't have been much unusual about this except for the fact that his mother was doing this completely naked and that she had left the door open. David's cock was quickly recovering from having been sucked and fucked for the first time down in the garage. It was rapidly making an obscene tent out of his mother's sheets.

“Hey Mom! Scoot over to the left a little bit.”

“But I won't be able to see myself in the mirror as well.”

“Yeah, but I'll be able to see you better.” David leered.

Dana actually blushed slightly at her son's lewd comment. However, not only did she scoot over, she arched her back to put her augmented breasts proudly on display. “Is that better baby?”

David couldn't hide his enthusiasm as he responded, “Oh yeah!” His cock was growing to its full length under the sheets. Unused to anything touching his cock when it was hard, David shuddered as the sheets shifted to accommodate his lengthening member.

Dana's big boobs jiggled like Jello as she brushed her teeth. She heard her son sigh, and she could see him staring intently in the mirror. She started exaggerating the motions needed to brush her teeth, which really set her large round breasts bouncing wildly.

“Damn Mom! I know you left the door open, but I feel like a peeping tom; the luckiest peeping tom in the world.” David guessed that his mother's teeth were now clean, but she kept brushing to put on a show for him. Suddenly he realized it was too good a show. “Wait Mom! Stop!”

Dana froze, “What's wrong.” If her breasts had stopped moving as quickly as she had, David might have maintained control, but her heavy jugs swayed like pendulums as they slowly came to rest.

It was too much for David's inexperienced cock. “I'm too...excited...Ugh! Think I'm...gonna...cum!”

Dana hurried back into the bedroom. “Oh no! Don't waste it son!”

David was bucking his hips like he was fucking the bed sheet, and large wet spots we forming as he came on the sheets. “I can't help it. I'm not used to boobs bouncing or anything soft rubbing against my hard cock.”

“Well, we'll just have to do something about that son. I intend to give you plenty of opportunity to practice on me! Are you staying hard?”

“Yeah, I think so.”

“Good, I need some more hard cock inside me.” Dana straddled her son, but wasn't used to his length. “I like fucking big cocks, but yours is one of the longest I've ever seen. I'm going to have to lift up a bit to get you inside me. While she talked, Dana fisted her son's shaft to guide it back inside her. Mother and son both sighed in pleasure as she slid down his pole. “Are you ready baby?”

“Sure am.” David sighed as he closed his eyes.

Dana started bouncing up and down, riding her own son in her bed. David opened his eyes. “Man I love bouncing tits!” He exclaimed. He reached up and grabbed hold of his mother's knockers. “Oh shit, cumming again!”

Dana scowled, “Damn it!” She rode her sons cock as best she could, milking it for cum and eeking what pleasure she could out of the short fuck, but she didn't climax this time. “We have really got to work on this son.”

Worried, David tried to assure his mother. “I'll be a good student, I promise!”

Dana couldn't stay frustrated with her boy. She giggled, “I know baby. In a few days, you'll be fucking like a porn star. For now, let's get some sleep. Remember though, if you wake up with a boner, you wake me up too.” David indicated that he understood as he cuddled up to his mother's curvaceous body.

Joseph tried the door and found it open, but it was a minor consolation. He heard the sounds of moaning and bodies slapping together, but he immediately knew it wasn't his mother. The sounds were coming from the TV. His mom had left a porn DVD in the player and had apparently fallen asleep. As he walked into the living room, Joseph cursed his luck. His mother was asleep, and if he had properly satisfied his cock with Dana he could simply head to his room. Instead he was planning to wake his mother up and ask her if he could fuck her.

It turned out he didn't even need to do that. Even though she had a shirt on, Ariel was naked from the waist down, and once again her sex toys were strewn about the living room. Trembling with intense need, Joseph stripped off his pants and aimed his aching tool at his mother's snatch. He sighed as he discovered her slit to be still wet. He couldn't believe he had been reduced to jabbing his hard cock into his mother's sleeping body, but he didn't even really think about the decision. It was just something he had to do.

Something else he had to do was cum. It horrified him to think about the possibility of impregnating his mother, but something about the forbidden possibility had his cock spewing forth cum before he was even half way inside. Joseph shouted “What's wrong with me?”

Ariel stirred, and wrapped her long legs around her son's body. She had pulled his spasming cock all the way inside her before she opened her eyes. “Mmm, I want you to wake me up like that from now on. That's almost enough to make me forgive you for leaving me all alone this weekend. I was so worried that your girlfriend was going to wear you out and leave you too tired to be seduced.”

“I don't have a girlfriend.” Joseph said without thinking.

“Your fuck buddy then. I don't care what you call her. I'm just glad you're fucking me again. Take me up to my room so we have room in my big bed to fuck properly.”

“Oh Hell!” Joseph moaned. He rested his head on his mother's chest. The question that was tormenting him was almost enough to get him to start fucking his mother again right on the couch. He knew he had to ask it now before he tried anything else.

Squeezing her son's head to her tits Ariel asked, “You're not planning on trying to resist me again, are you?”

“No, I don't think I'm capable of that once I get started anymore.” Joseph sighed. “I've got a question that's bothering me, but just thinking about it makes my cock want to explode inside of you. Ugh! I can't help it. Just thinking about it; it's too much. I can't control myself.” Joseph grabbed his mother's hips and started banging her again.

Ariel responded enthusiastically with her body. “Oh, that must be a good question. Ask it. Ask me anything! There's no way I could lie to you with your big dick filling me up son!”

Frantically fucking his mother, Joseph couldn't get the question out. “Are you? Could you be? Could I be?”

“Damn it Joseph! I don't know what you're getting at, but you're giving it to your Mommy good tonight!”

“Oh shit! What I'm trying to ask is: Is this safe?”

“Safe? Like as in safe sex? Sometimes you're a silly boy Joseph.”

“Mommy! Just answer the question! Thinking about fathering a baby in you is killing me!” Joseph yelled as he slammed his giant cock into his mother hard.

“It can't be bothering you that much.” Ariel muttered under her breath. Before she could give a serious answer, her eyes rolled back into her head as Joseph's intense fucking caused his sexy mother to cum; shaking, she pulled up her shirt, baring one of her large natural breasts and squeezing on it as she orgasmed. The added visual stimulation was too much for Joseph, who dumped another load into, what he feared, was his mother's unprotected pussy.

When mother and son caught their breath, Joseph accused his mother. “We're having unsafe sex aren't we? I could have just knocked you up if I haven't done it earlier in the week.”

“Joesph, do you have any brothers or sisters?”

“What's me being an only child got to do with me maybe knocking you up?”

Ariel rolled her eyes. “I'm going to give your cock a chance to return some blood to your brain before I answer that.”

Finally Joseph realized what his mother's question implied. “Wait, you said you were cheating on Dad all the time. With all the acting slutty and stuff, you'd have had a bun in the oven long before now if you weren't taking precautions. I mean, if I don't have any brothers and sisters that must mean you're on the pill or that patch thing, or something. Right?”

“You were really worried about that, weren't you? But not worried enough to wake me up and ask before you started fucking me in my sleep?”

“No, I'm so ashamed. I shouldn't have done that, but I couldn't help myself. It's even worse than what I want to do now.”

“And what's that?” Ariel asked grinning.

“I want to take my sexy Mommy upstairs and cuddle her, and kiss her sexy lips, and stare into her beautiful blue eyes. Ugh! I can't believe it. Telling you those things is making my cock get hard again. I'm so confused. Will you suck my dick Mommy? It's so sore from all the fucking I did this weekend.”

“Don't worry; Mommy's going to take good care of her confused boy.”

“Ugh! That's what I'm afraid of.” Joseph muttered, even as he ogled his mother's round ass sway as she led her son up the stairs.

David had woken up twice during the night to fuck his mother again, but each time he came almost instantly inside her. Dana was quite frustrated when the alarm clock went off. “David, I know you're trying to satisfy Mommy, but we're going to have to try something different this morning. Have any of the boys at school talked about eating pussy?”

“I've heard the term, but I was too embarrassed to admit that it didn't make much sense to me. I mean, you can only eat something once, right? The guys who talk about it say their girlfriends can't get enough of it.”

“Well, it's more like licking pussy really. Kind of like a blow job involves sucking on a guys cock, not blowing on it. They're right though. If you're eating pussy correctly, girls can't get enough of it. I'm going to teach you a way of eating pussy that will guarantee you get that result out of a woman every time.”

“Does it make sense that just talking about this is giving me a hard on?”

“It certainly does. Sucking on a long fat cock always makes my pussy wet. Now get between my legs and put your face close to my crotch. You'll have an easy time seeing all my girly parts because I'm shaved and waxed.” Pointing to the top of her slit, and pulling herself open with her other hand, Dana continued. “That's my clit. My whole pussy is sensitive, but this is super sensitive. No teeth on it, and don't concentrate all your attention here unless I tell you to.”

“How do I know if I'm spending too much or too little time on that one spot?”

“That's the beauty of what I'm about to have you do to me. You won't really have to think about it. Now swirl your tongue around down there to get an idea of what it feels like. Mmm... Yeah, just like that.”

“Wow! I think I'm really going to like this. Tasting your juices is making me really hard. What do I do next?”

“Trace the letters of the alphabet on my pussy with your tongue.”

“That's all there is too it?”

“Yep.”

“And this is going to drive you wild?”

“It sure will.”

“Capital or lowercase letters?”

Getting impatient, Dana said, “Either way works. You pick. You can even let me try to guess. Now get to work.” With her last sentence Dana pushed her son's head down into her dripping pussy.

David did as he was told, and it didn't take long to make his mother cry out in pleasure. It only took until the letter G in fact. He heard his mother shouting, “I'm cumming! Fuck I needed that so bad!” The hung teen had been a bit skeptical about the secret of driving women to orgasm with his tongue. He tried to form his letters with greater precision, and was rewarded with a second orgasm from his mother on the letter O.

He felt his cock shooting off cum as he made his mother climax a second time, but he hardly cared. He just wanted to nurse more sweet pussy juice from her snatch. Everything about the experience was intoxicating to him, the taste, the smell, the feel of his head nestled between his mother's thighs. He got two more orgasms out of his horny mother by the time he reached the letter Z. They both needed to catch their breath afterwards. Dana from her multiple orgasms, and David because it was hard to breath while trying to bury your face in your own mother's pussy.

David was the first to speak. “Sorry Mom. I think I came again without anything touching my dick.” His cock was still hard, but there were globs of cum on the sheets where he had been kneeling.

“Capital.”

“Huh?” David asked, not understanding his mother's response.

“You used capital letters on me.”

“Oh, yeah, I did. You're not mad at me for cumming again?”

“That's actually not an uncommon male response to eating a woman's pussy. You are being bombarded with a lot of female hormones while you're doing that.”

“So that's maybe why I feel a little dizzy right now?”

“Maybe.” Dana agreed. “Want to see if lower case letters leave you feeling any dizzier?”

David licked his lips eagerly. “Oh hell yeah!” he shouted before diving into his mother's sex for a second time. He actually got his mother to cum five times by the time he hit the lowercase z, but this time he didn't stop at the end of the alphabet.

Suddenly, his mother called out. “What letter was that? Do it again. Mmm, that's good, but I meant the one before that one. Yes! Fuck yes! I can't tell what letter that's supposed to be, but center your tongue on Mommy's clit and don't stop until I tell you to!” Dana wailed like a banshee as she came over and over again under her son's swirling tongue. Finally she could take no more. “Mercy! Stop son! My clit can't take any more.”

When she was finally able to catch her breath, Dana asked. “What the fuck did you do to me? I couldn't tell what letter that was, but I couldn't stop cumming while you were using it on me.”

David blushed. “I figured that if both lower and upper case letters worked, the special symbols on a keyboard would work just as well.”

“Even better, it would seem. So what symbol reduced me to a screaming, cumming, slut?”

“The @ symbol; the one that gets used in email addresses.”

“Cleaver boy, you made your Mom very, very happy with that decision.”

“So you're not mad that I came again while I was eating you?”

“Not at all, you earned both those orgasms. Let's go get in the shower together. We both have to get to school, much as I'd like to continue your lessons immediately. However, if you just happen to get another hard on in the shower, I won't be opposed to you seeing how long you can last inside me now that you've proven yourself to be a natural pussy eater.”

David grinned. “Like a hard on I might get if I were soaping up my mother's giant tits in the shower?”

Dana giggled right back at her son. “Yeah, that's exactly the sort of thing I was talking about.”

Joseph awoke unsure of exactly where he was. He was in a bed with an extremely hard but sore cock. He had to trace his memories forward from the time he pulled his aching cock out of his sexy counselor the night before. Then it became even sorer on the bike ride home. He blushed in shame as he remembered how it felt to fill his mother's pussy with cum while afraid he was risking getting her pregnant. Then he had let his own mother lead him to her own bed so he could make love to her all night long. His cock was too sore to fuck much, but it didn't want to get soft either. Mostly he had held his cock still inside his mother's pussy while his hands roamed all over her luscious body.

He couldn't believe how much time he had spent telling his own mother how beautiful and sexy she was. He also couldn't believe how much time he spent talking about “making love to Mommy” and how good it felt to “cuddle Mommy”. Thankfully, they must have become too warm with their bodies pressed together under the covers during the night. The only good thing that had happened to Joseph in the last 12 hours was not waking up with a slutty, sexy, insatiable parent in his arms.

His attempt to slip out of his mother's room unnoticed failed. “Where do you think you're going?”

“I need to get a shower before school.”

“You've got time; the alarm clock hasn't even gone off yet. Get back into bed with Mommy.”

Foolishly, Joseph looked back at his mother's bed. She had pulled the covers back invitingly for him. Worse still, this exposed her beautiful naked body to his hungry gaze. Her full tits and blond bush were nearly irresistible. What did him in though, was her index finger beckoning him back to his mother's side. His cock surged with need, and the hope of catching Dana in her office before school opened faded. Here was an equally hot woman who could satisfy his need to cum right now.

Moving back to the bed, and preparing to mount his mother, Joseph protested. “I don't understand it. With everything I did this weekend, I should be able to go a week without being this horny again.”

“It doesn't work that way.”

“Huh?” Joseph grunted. “Oh Mommy! It feels so good to slide my big hard dick back into your pussy. It makes me forget how sore it is; even though fucking you is just going to make it even more painful after we're done.”

“So you fucked, someone, many times this weekend.” Ariel said carefully. When Joseph reluctantly nodded, Ariel continued. “The more you fuck, the more you need to fuck.”

“Oh shit! So that's why you look so irresistibly beautiful to me now? Or why my cock feels so fucking good inside you? Or why I can't keep myself from filling my hands up with your big, bouncing tits?”

“That's it. You were trying to make so that you didn't need to fuck me, but...”

Joseph finished for his mother. “I really made it so that I need you more than ever. It's not fair Mommy! I tried to be a good boy, but everything I do just seems to lead me deeper into incest.”

“And deeper into my pussy.”

“That too.” Joseph grunted. He had taken hold of his mother's narrow waist and was banging away with abandon. “Help me Mommy, I need to cum, but my cock is really tired and sore. I'm banging every inch of my fat cock into your belly, but it's not enough.” Ariel's long hair was like a disheveled halo around her head as Joseph fucked his mother hard.

“Oh, my poor baby's cock it tired? Mommy would never know from how big and hard it feels inside her. Think about how good it feels to spray your cum deep into Mommy's flat belly.”

“Yeah, it does feel so good to do that.” Joseph agreed in a sexual daze.

“Then you can rest your head on my tits just like you did last night. You love Mommy's tits, don't you.”

“I do, I do!” Joseph admitted. “And your nipples.”

“Oh, even better. After you cum in Mommy's belly, you can suck on my nipples like a baby. My, big, fat, puffy nipples can be in your mouth as soon as you cum.”

“Yes! Yes! I want that!” Ariel's nasty words had pushed her son's tired cock into another orgasm. As soon as he was done cumming, Joseph took one of his mother's tits in his mouth and nursed contentedly on her conical nipples. He hated getting out of his mother's warm bed when the alarm clock finally went off.
