Kyle and Julie had been fucking non-stop for nearly an hour. She had cum six more times, with each orgasm seemingly more intense than the last. It was as if her body and especially her vagina were slowly being trained to love her son's cock more and more. He'd already given her more orgasms today than she'd had in the entire month with her husband, and each one was on an entirely different level than what she'd ever experienced with Jim.

Kyle finally dumped his cum load deep into Julie's twat and rolled off of her, completely exhausted.

She'd had one last orgasm at the same time he did, because it felt so very good to feel his cum squirting deep inside her. Not only was the sexual pleasure incredible, but she got a heady rush for considering that this cum load just might be the one to impregnate her.

As her orgasm finally faded away, she thought, My son is breeding me! For real! Like a stud horse breeding one of his mares. It's so wicked that I'm going to have my son's baby. No matter what happens, I'll always get a secret thrill looking at my youngest son or daughter, knowing he or she was born through incest! Kyle and I will share that naughty secret for the rest of our lives, with only my poor hubby also knowing the truth.

She propped her hips up with a pillow to keep all his potent sperm-sauce inside of her.

Her tank top was still up around her armpits. He'd wound up playing with her huge tits for the better part of the last hour, somehow managing to do that while pounding her cunt nearly non-stop that entire time. She'd made a mental note more than once to warn him after the fucking was over that such breast play was off limits. But now that it was over, she was so fucked out that she plain forgot.

Besides, deep down, she didn't really want him to stop.

In fact, in the post-orgasmic glow, he continued to fondle her great globes. He even lightly licked on and around one of her nipples. He was secretly thrilled that her "dispassionate copulation" plan was already starting to fall apart.

As he kept playing with her round tits, he asked, "So, Mom, was that good for you?"

She gushed, "Oh my God! Dear Lord! You have NO idea!"

But then she remembered, Clinical! Dispassionate! I'm a married woman! He's way too enthusiastic and talented already. God help my poor pussy if I encourage him more!

She tried again. "Er, what I mean to say is, yeah, I must admit it felt pretty good for me. I'm sure you could tell, since I was, uh, fairly vocal at times."

He smirked, because that was such an understatement.

She continued, carefully, "I suppose that's inevitable, because nature has made our bodies a certain way, to encourage procreation. But that doesn't matter. Whatever pleasure I feel is irrelevant to the goal of getting knocked up."

He pointed out, "But Mom. I read that a woman is much more likely to conceive after she's had a really big climax."

She looked at him suspiciously. "Really?!"

"Really. I found an article about it. I can show you."

She thought, Oh shit! I kind of hope that isn't true, because what if it is?! I'd almost be obliged to get my brains fucked clear out of my head over and over again! And all so he can successfully breed me, which is way too arousing a thought, in and of itself!

What the hell have I gotten myself into?! How is my marriage going to survive this?! Already I can tell that, compared to my son, my hubby is like a eunuch! He might as well be totally castrated, compared to Kyle's magnificent baseball bat! UGH! And he just keeps going and going, drilling that bat in and out of me, like some kind of relentless fucking machine!

She tried to avoid the whole topic, because she didn't want to think too much at the moment. "Sugar, why don't you go down to your room and have a nap? You must be exhausted."

"Okay, Mom. Whatever you say." He felt like he didn't need a nap at all, and he didn't intend to take one. In fact, he was feeling even more energized than when they started. But he understood she needed to be alone for a while to mentally process things.

He'd been going back and forth between licking each of her nipples. He gave each nipple one last kiss and lick, and a few final tit squeezes for good measure. Then he disengaged and got up off the bed.

She only pulled her tank top back into place after he'd left, when doing that was basically pointless. She thought, I suppose some breast play can't be helped. He's so very tit-obsessed that trying to stop that would be like trying to hold back a river with my bare hands.

Besides, his touch there really turns me on. I know he pretty much exclusively dates busty girls. He clearly has had a lot of tit play practice, so he knows just how to drive me wild with his wandering fingers. And even his tongue! Jesus! So wicked. But that's okay, because if I cum faster, that'll help him cum faster, and that'll actually help him breed me faster too.

UNGH! I really should stop using the word "breed." It makes me feel like... I don't even know. But it's just too damn suggestive! "Copulate" is definitely safer and better. I'm going to stick to that from now on.

Kyle went to his room. All that fucking was exhausting, even though he was muscular and at peak fitness. Despite his intention not to nap, he fell fast asleep in a matter of minutes.

He woke an hour later to someone stroking the side of his head. He turned to find his mother sitting on the edge of his bed.

She smiled down at him. "Wake up, sleepyhead. Time to get back to 'work.'" She chuckled at her knowing use of the word "work."

He took a good, long look at her. She was wearing a silky red robe, the same robe she'd worn the night when she'd told him Jim had agreed to let him impregnate her. Except this time it was wide open in front, with the sash very loosely tied. Furthermore, she was leaning way over towards him to wake him. That allowed her massive tits to fall free of the robe altogether!

He woke up in a hurry, thanks to that arresting sight! It was all he could do not to reach out and start fondling her dangling udders, and even suckling on them. But he remembered he needed to play a long game to win his ultimate prize, and part of that meant not being too pushy too soon.

It took great willpower, but he tried his best to pretend she wasn't accidentally flashing him with a drooping tit show for the ages. "What time is it?" he asked, rubbing his eyes.

She'd been not-so-furtively checking him out too. He'd gone to sleep without bothering to put any clothes on. And it was the middle of the day, so there had been no need for him to even tug a sheet over his body. As a result, his entire hunky naked body was on display.

She was chomping at the bit! She could hardly wait to get fucked by her handsome and strong son yet again.

She was almost shocked to see his penis in a flaccid state, but she was confident it wouldn't stay that way for long. In fact, even as she watched, it started to rapidly engorge, no doubt helped along by her provocative topless pose.

She finally stood up, which brought her arousing titty show to an end, more or less. At least, her nipples were covered again, but all of her dramatic cleavage was still on display, as the robe remained open down to her belly button.

She told him, "It's three-thirty. We have time for one more session before your dad comes home. Why don't you freshen up and then come back to my bedroom, okay?"

"Okay," he answered with a grin. He was highly restrained with his short response, given that he knew "come back to my bedroom" was code for "come skewer me with your incredible cock some more."

His penis had just gotten fully erect again, mostly thanks to her titty display. But even without that, he could have willed it to a firm stiffness merely from thinking about the fact that he was about to fuck the woman of his dreams for the third time!

Julie found herself hopelessly staring at his revived hard-on even more. Have mercy! I so want to say "screw the whole clinical approach." But I'm married! Already, I don't know how I'll ever get back to normal. I can't let things get out of hand more than they already are!

But God, do I love getting fucked by my son and his massive cock! Just look at that monster! And he's just so hunky and handsome all around. My heart flutters in a very unmotherly way every time I see him, starting long before this crazy breeding plan began. This is bad, this is really bad. I've gotta stay in control!

She kept staring at his exposed boner while unthinkingly licking her lips. It took her a full minute or longer before she pulled her willpower together and managed to say, "Oh, and please at least put some boxers on, okay?"

"No problem."

She left. Even the way she walked out of his room was a sight to see, since the red robe barely covered all of her fulsome ass cheeks.

Kyle washed his face and went back down to his parents' bedroom. Although he had put his boxers on, his boner lewdly bounced and tented as he walked.

His mother was sitting at the foot of the bed waiting for him, still loosely wearing the robe. She unthinkingly licked her lips some more as she watched his erection wobble wildly inside his boxers.

Hmmm, she thought. I wonder what it would be like to suck on that fat thing. Could I even get it in my mouth?! Would I want to even try?! It's too big! It's probably a good thing that blowjobs are off the menu, since they don't help get me pregnant. Sucking and bobbing on that monster would be a nightmare!

He noticed a wooden chair nearby. "What's that for?" he asked about the chair, which he'd never seen in her bedroom before.

"Sit down and I'll tell you," she said.

Kyle sat in the chair, which he noticed had no armrests. He correctly guessed that could be why she was using that one instead of any other chair already in the room.

Julie had her long legs crossed, and he couldn't help but admire them.

He thought, I can't believe that I had those beautiful legs wrapped around me earlier as I drilled her cunt. My MOM'S cunt! It all seems like one big wet dream. And yet the mild ache in my penis is just one clue that all of it had really happened!

She told him, "They say that ninety percent of a man's sperm never makes it through the opening to the woman's cervix. So I have an idea that might greatly increase our chances of getting me pregnant."

"Okay," he said, very curious and intrigued.

"If we could somehow get your, uh, battering ram, through the head of my cervix …when you ejaculate, your sperm will have already bypassed one of their biggest obstacles."

"Is that possible?" he asked with genuine interest.

She couldn't resist gawking at his crotch. She was transfixed even more than usual, because more than half of his erection was accidentally sticking out through the slit in front of his boxers!

Actually, it wasn't an accident, but he figured she didn't need to know that.

She continued to stare at his exposed cock as she said in amazement, "Well, you definitely have the length for it! And… and the width!"

Her heart thumped wildly as she thought, This is my ONE CHANCE to really go wild and live out all my greatest sexual fantasies with my hunky stud of a son. He's got the perfect cock! I need to get all my ya-yas out of my system while, uh, generally remaining dispassionate. At least, I can't let on to him how much he's affecting me! Then, I can go back to my humdrum existence and I'll at least have these memories.

She finally managed to make eye contact with him. "But, um, we'd have to try a new position in order to achieve maximum depth. Would you be okay with that?"

"Why wouldn't I?" he asked back. "It sounds like fun!"

"Well, the first two times, we were under the sheet and you were on top. This time, we'd have to be a little more exposed... and I'd have to be on top of you," she said with increasing bashfulness. She was trying to hide it, but her arousal was steadily rising too as she contemplated her new plan.

She lamely added, "And remember this isn't about 'fun,' at least not for me."

He shrugged. "Whatever has to be done, I suppose," he said, pretending indifference. Actually, the new position sounded downright fantastic to him.

She smiled at him lovingly. "You are such a sweetheart, doing this for me."

It took all his willpower not to snort derisively at that, since he was enjoying this more than anything he'd ever done in his life.

She stood up, walked over to him, and gave a little tug on the leg of his boxers. "Get these off," she whispered in an urgent and needy way.

He slipped out of his boxers, causing his big dick to bob up and down.

Julie stared at her boy's cock and unthinkingly licked her lips again. Good God, do I love that thing! I'm going to have to redouble my effort to be dispassionate, because I could see myself falling hopelessly in love with getting fucked by my son, if I don't watch out! We only have such a short time together.

She couldn't resist gawking at his turgid cock-meat even more. "I don't know where you got your size. It must have been my side of the family."

"Dad's isn't this big?" Kyle asked with seeming innocence, although he already knew the answer. He held his hard-on from below and pointed it in her direction.

Her heart skipped a beat, and her sopping wet pussy twitched in anticipation. She was almost rendered speechless, because her fuck-need was suddenly so great. "Your father's penis is... fair sized, but I would say that what you have down there is, well... how shall I say this... much, much larger than most. I have a feeling it's going to make lots of beautiful babies... starting with ours." She smiled warmly.

"I hope so," he said proudly. "I can't wait until I've successfully bred you."

She felt shivers race up and down her spine from the "breed" word. That never failed to at least give her body a tingle.

"Well, mister..." she said as she reached under her robe and slid her panties down her long legs. She kicked them to the side and smiled at him.

She remained standing there with her bald pussy on full display. "We have a baby to make. Let's not waste time." She started to move to the bed.

"Mom... I..." he started, shyly.

"What's wrong, Sugar?" she asked.

"I was just wondering if... if maybe you'd..." He tried to spit out his words as he looked at the swell of his mother's enormous breasts. "If you'd..."

"Take off my robe before we get started?" she asked, anticipating his tit-obsessed thoughts.

"Yeah," he said bashfully.

"That would leave me completely naked!" She acted a bit scandalized by this suggestion. In fact, she was secretly craving for that exact thing to happen.

"I know!" he said in wide-eyed wonder. It wasn't hard for him to imagine how she'd look that way, especially because her silky red robe was opening more and more in front. He could see most of her massive tits, and even all of her swollen and abused pussy! Still, never in his life had he seen her completely naked.

"I don't know, my love. I promised your father that I'd keep our sessions as unrevealing and clinical as possible." Although she said those words, in her heart she was all but pleading with him to talk her into changing her mind.

"Yeah but... you've seen me naked today. It's no big deal, right?" Kyle asked. "In fact, you're seeing all of me right now." He pointed his flagpole of a cock up towards her even more dramatically.

She was seriously tempted to fall to her knees and take that cock in both hands! But she kept her cool, and said, "Sugar, your penis is a necessary part of this process, but... my breasts aren't. I just don't know if it's a good idea."

"What about your orgasms? Are those a necessary part of this process?"

"Now hold on a minute, mister. Those are totally beyond my control. I can't help but feel some pleasure, as much as I try to fight it."

"True. But I told you that the more you cum, the more you're likely to conceive. Maybe the reason Dad hasn't gotten you pregnant is that he doesn't really ring your chimes."

She thought with a start, You know what? He may be right about that! If it takes a big orgasm, then Jim is totally hopeless! Whereas my son will be able to breed me in a matter of hours!

However, she told him, "Let's not get distracted with side issues." She was so horny that even her chiding was sexy and flirty, because she playfully wagged a finger at him.

He said, "The way I figure, the more you cum, the better. And the more I cum, that's better still, because each time I do, I pump more baby batter in you to breed you. Right?"

She felt goose bumps all over. "Right."

She appeared calm on the outside, but thought, My son is breeding me! How hot is that?! When I have the baby, for the rest of my life, I'll be reminded how he drilled me and knocked me up with his huge, unstoppable cock! Mmmm!

He went on, while all but wagging his boner at her, "So, if some breast play helps you cum, and/or helps me cum, that's a big help with our overall breeding plan. Right? I'm sure it'll help. At worst, it can't hurt."

She wanted to be convinced, and he'd done it, using basically the same logic she'd already told herself earlier about his tit play then. The fact that he'd come to the same conclusion gave her greater confidence that such logic was sound and it wasn't just her lust leading her on.

She said with as much reluctance as she could manage, "Well... I suppose I can't argue with that."


She chuckled. "However! Don't you DARE tell your father that I got a little naked here and there. Or that you touched my breasts. Please?! It would break his heart."

"Yeah... he'd be pissed as hell." Kyle smiled almost wickedly. The way he figured, Jim had destroyed his marriage by fucking his secretary. It was just that Jim and Julie didn't know their marriage was doomed yet. Jim pretty much deserved whatever he had coming, for cheating on his divine goddess of a wife.

Julie stood there with a hand on the sash to her robe. But her hand stayed still as she chided him, "You haven't promised me yet."

He rolled his eyes. "Of course! Duh! You know I love him and don't want to hurt him. It's just that I really, really enjoy fucking you too."

That answer pointed to a very problematic future, especially since they knew that everything he said was true. Clearly, he did love his father, but just as clearly, his desire to fuck his mother was trumping everything else, including that. But she decided to ignore that for now.

She said, "Well, okay then." She sexily undid her sash, then let her robe fall completely open in front. She felt even more flushed and aroused. Good Lord! This is so wanton and wicked! I feel so... exposed! Up until recently, I'd been extremely careful to never, ever expose myself to him, and now look at me!

But then she suddenly changed moods, at least on the outside. She put her hands on her waist and glared at her son. "And one more thing, buster. Just because my boobs are fully exposed and they're bouncing around on you doesn't mean they're up for grabs, understand?"

"Perfectly." Kyle answered. But then he added, "Although… I might end up accidentally holding them and playing with them from time to time. I'm such a boob-focused guy, it kind of comes naturally to me, without thinking."

She rolled her eyes at him. "Ugh! You really are a case!"

But then she finished her sexy striptease, letting her red robe slide all the way off her body until it puddled around her feet.

He wanted to play it cool so she wouldn't get cold feet about losing the robe. However, he couldn't stop himself from gushing as he took in her hourglass figure in the buff for the very first time, "MOM! You're magnificent! Utterly magnificent!"

She wasn't used to such compliments. In particular, the intense look of lust and love in her son's eyes blew her mind, because she knew it was completely genuine. To try to downplay the moment, she joked, "I think you mean 'udderly magnificent.' She held her huge orbs from below and slightly hefted them up.

"That too!"

The two of them shared a laugh over her bad pun, but at the same time, her arousal soared to the sky.

His arousal was already somewhere up in the stars.

Her need to get seriously fucked was growing by the second as well. Standing completely naked for her awed son was a very heady aphrodisiac for her. She worried that she might even start trembling if she stood there for long.

She moved to where he sat in the chair and boldly threw her leg over his lap, straddling him. "Are you sure you're gonna be able to handle the weight of me on top of you?"

"Yeah, no problem," he answered. He briefly and playfully struck a weight-lifter pose, flexing his arm muscles.

Julie sat on Kyle's lap, with his big hard dick wedged up against her swollen clit. She brought her feet up and placed her heels on the back edge of the seat of the chair. She rested her hands on his shoulders.

He could feel the full weight of his mother's ass resting on his lap.

He gawked at her enormous breasts. The "udders" jutted dramatically off her chest and were capped with large, stiff nipples.

Suddenly, her great tits were the center of his attention, even more so than usual. He was so transfixed that he unthinkingly cupped them from below and hefted them up slightly, in wide-eyed wonder.

She basked in his attention and his talented touch, even as she squirmed with lusty desire on his lap. She couldn't resist boasting with a smile, "See? You're not the only one in this family who's well endowed."

"Wow... they're beautiful!" he said with even more awe.

"They're a bother to me. They're too heavy... and they'll get a lot heavier as I progress into my pregnancy... but first I have to GET pregnant which is never gonna happen if you just sit there staring," she said with a giggle.

"Oh... sorry," he said, while still boob-obsessed.

"It's okay, love. I realize it's not every day that a boy your age gets this close to boobs as big as mine," she said as she combed through Kyle's dark brown hair with her long nails, letting him fondle.

She went on, "I know for a fact that NO girl in your school has breasts as large as these, not even Melinda or Charlotte."

She named two of the girls that she knew he liked fucking the most often, due to their general beauty, but especially their unusually large breast sizes. They were arguably the two hottest girls in school, and yet they never dated because they always wanted to be available if Kyle wanted another "booty call" with them. He had a firm rule about never dating (or just fucking) a girl who was in a relationship with someone else.

She added, with justified pride at her natural endowment, "So it must be a little overwhelming for you now."

"A little," he said, his eyes still glued to his mother's amazing chest.

She'd been stalling for time a little bit to give him a chance to enjoy her tits, despite the fact that he'd played with them plenty during their last fuck session in particular. But she was chomping at the bit to get royally fucked again. So she asked him, "Well, shall we try and get that big baby-maker of yours into my cervix?"

"Yes, please!" He finally looked back into her eyes. He was eager for more fucking too.

Julie moved forward and her spongy tit-sacks pressed against his chest. She lifted her ass, grabbed his meaty pecker, and positioned the bulbous knob into the fleshy groove between the swollen pink lips of her labia. She lowered her ass back down.

She had to slightly shake her head in wonder. I still can't believe we're doing this, and that my hubby has given us full permission!

Kyle's cock slowly stretched his mother's pouch as it sunk in inch by inch.

He felt his fat cockhead grind against the back wall of her cunt when he finally bottomed out a couple of minutes later.

Julie held her son tight, resting her head on his shoulder as she worked her hips back and forth. For a good five minutes, she worked the lips of her cervix against the tip of her baby's cock.

"Come on, Sugar, we've gotta work it through." She was panting heavily from the struggle.

She started to bounce slightly on her son's lap. She thought with wicked pride, I know I'm a hot fuck! My son must LOVE fucking me. I can see it on his face! Melinda and Charlotte can eat my heart out! I'm twice the fuck they'll ever be, combined! So there!

Already, she was frequently forgetting how she was supposed to stay unemotional.

It wasn't long before Kyle felt his fat knob work itself into the groove of his mother's cervical lips.

"Oh my God, yes! Thrust your hips, baby! I can feel it going in... So deep! ... That's it, work it through! UNNGH!" she said with a victorious grunt.

Finally, he felt his cockhead slide through the lips and into her cervix.

"Yessssssss! Oh darling, you did it! You're inside my cervix!" Julie announced with even more joy and arousal.

She worked a good inch of her son's thick shaft into her secret chamber. Her cervical ring pulsed all over it, closing tight around the thick invader.

After adjusting to the strange but delightful new sensation, she advised him, "We need to keep it inside. I want you to stay as still as you can while I ride you!"

For the next 15 minutes, Julie did a sexy little bump and grind. Using her strong cunt muscles, she squeezed and released, and squeezed and released, over and over, trying to milk an orgasm from him, but at the same time keeping the tip of his cock inside her precious cervix.

"How are you feeling, love?" she asked after a long time with no talking, just lots of panting.

It went without saying that he was enjoying every last second, even though they were relatively restrained compared to their earlier fucking. The pleasure was like an endless river washing over the both of them.

He came out of a deep reverie to say, "I feel GREAT!"

She chuckled. "I figured as much. But what I'm asking is, are you close to cumming yet?"

"I don't know if I'm gonna be able to cum this way, unless I thrust," he responded, honestly. Thanks to his great stamina, it really did take a lot to get him to cum.

"No, you can't thrust, Sugar. I have to keep you inside my cervix," she said insistently.

She thought for a moment, while still working her hips in a small circle on his manhood. Then she came to a decision. "Okay, there's only one way this is gonna work. We both have to completely let go."

"What do you mean?" he asked, genuinely confused.

"What I mean is, for a few minutes, we have to forget that we're mother and son. We have to break the rules and completely let go. If we do this, I think we'll be able to excite an orgasm out of you."

His heart raced faster to hear that great news. But still, he asked, "What do you mean by 'break the rules?'"

"We'll have to do whatever we can to heat things up. That might mean kissing on the lips as mother and son never should, or saying dirty things like we're genuine lovers, or who knows what. But you need to understand that what I'm about to do will never, ever happen again. I'm only trying this to get you excited for this one special breeding procedure, understand?"

She gave him a severe, motherly look, despite the fact that she was sitting buck naked on his lap and he was balls-deep inside her, with his hands cupping her huge tits from below.

"Yeah," he said, trying not to show too much excitement.

He thought, The whole "clinical" and "dispassionate" bullshit is already slowly going by the wayside. But this'll help speed that up in a big way! I love it!

As Julie continued to work her cunt muscles like a pro, she looked straight into Kyle's eyes. Slowly, she brought her lips to his and gave him a slow sensual kiss. Then another. And then another.

Then she pulled his face to her big pillowy boobs.

"Oh sweet baby... suck my big soft titties, lover." She moaned needfully.

He began doing just that, and resumed holding and sensually caressing them with both hands as well.
