Chapter 2
Six months later Megan was finally showing; her toned belly was starting to soften and swell as her body carried out its evolutionary programming. As it turned out, Mason had successfully impregnated the enticing nineteen year-old the first time he had lost control inside her fertile babymaker, but that hadn’t stopped Megan’s reproductive instincts from driving her to copulate with the willing young stud again and again over the next few months to ensure that the pregnancy took. Unbeknownst to Mason, Megan’s promiscuous body had also enticed a few other prospective fathers into ecstatically filling her womb with their potent seed along the way, just in case, but these passionate flings ultimately amounted to empty pleasure, because even though she didn’t know it yet, Megan had already been bred.
She had immediately realized what her missed period indicated, of course, and was unsurprised when the test confirmed her fears. Well, there’s really nothing I could have done to prevent it, she told herself, secretly looking forward to feeling her belly swelling entirely beyond her control over the next few months. With how badly my body was trying to get me pregnant, and with how many guys I’ve been letting cum inside me, it was pretty much inevitable that I’d get knocked up.
Megan’s best friend Mona was the first to notice her gently protruding paunch. Shy, nerdy, and petite, the mousy brunette couldn’t be more unlike the popular, outgoing Megan, but despite their differences they had become fast friends after meeting at the beginning of freshman year. The bright twenty year-old had quickly connected the dots between Megan’s softer, slightly flushed appearance and the odd behavior changes she had noticed in her friend over the past few months.
“You’re, um, glowing a bit more than usual, Megan,” Mona suggested meekly, trying to find the most tactful way to broach the topic.
“I know,” Megan responded with a resplendent smile, “that’s because I’m pregnant!”
“Oh, um, congratulations,” Mona awkwardly stammered. Her suspicions were confirmed, but she was flabbergasted nonetheless. “Don’t you think you’re a bit, um, young for that? Why didn’t you just get an abortion when you found out?”
Since reproduction was what her body was designed for, it had never occurred to Megan that she could get an abortion, but now that Mona had suggested it the idea somehow seemed doubly ridiculous.
“Mona,” Megan answered patiently, “you just don’t understand how strongly my body was trying to get me pregnant. I didn’t really want to, but my body is so flushed with sex hormones all the time, and my reproductive instincts are so strong, there’s really nothing I could have done to stop it. Hell, even now, just thinking about using my pussy to tease Mason into spurting all up inside me is making me all horny again, and I’m already pregnant!” the knocked-up young slut gushed, massaging her small bump as a flush crept up her neck.
“What? That doesn’t even make sense!” Mona replied. “We all have a sex drive, sure, but we can still control it, or at least practice safe sex if we want to… um, indulge.” The sheltered nerd blushed a bit at the scandalous thought of sexual intercourse. She had the same urges as everyone else, of course, but the idea of sex, and especially of herself or her best friend having unprotected sex, rutting like animals, just made her feel uncomfortable. “This really doesn’t sound like you at all Megan. Is there something you’re not telling me?”
“Not really; you just haven’t realized it about yourself yet,” Megan answered confidently. “You should talk to Dr. Jeff – he did a wonderful job of explaining how women’s bodies are designed to try to get us pregnant whether we want to or not, and how men’s bodies are designed to get them to impregnate us.” Thinking back to the lecture made Megan remember how important it was that she had discovered this about herself, and she realized that it was just as important that her best friend learn about Human Reproduction as well.
“What does you being pregnant have to do with Dr. Jeff? Did he do something in Biology last semester?”
“He didn’t really do anything. He just gave a lecture about Human Reproduction that made me realize just how perfectly our bodies are designed for breeding. There’s all kinds of sex hormones, and instincts, and, uh, you really just need to talk to Dr. Jeff about this, because he can explain it all much better than I can! He’ll make you understand,” Megan concluded, though to Mona her last sentence had sounded strangely ominous.
“Well, I do think we should go talk to Dr. Jeff, if only to see what he really meant,” Mona said. “I’m sure that whatever it was, he didn’t mean for you to actually go out and get yourself pregnant! Maybe there’s still something we can do about it. I have class in like twenty minutes, but hopefully that’ll be enough time to set things straight.”
“Okay!” Megan happily agreed, though she was secretly convinced that Mona would be the one Dr. Jeff set straight.
And so Mona went with her pregnant friend to confront Dr. Jeff in his office. “Megan keeps saying that her getting pregnant was all thanks to you, Dr. Jeff, and that you showed her the truth about herself. What does she mean by that?”
“Wait, what?” Dr. Jeff asked, looking up from his desk in startled confusion at the outlandish accusation. “I have no idea what you’re talking about. I didn’t even know that Megan was pregnant, and I definitely didn’t have anything to do with it!”
“But it is all thanks to you, Dr. Jeff!” Megan insisted. “It was that day you talked about Human Reproduction and how our fertile bodies, instincts, and hormones are constantly driving us to procreate. After that lecture, the guys have been inseminating any girl who’ll let them, and most of the other girls from class are pregnant too! That sneaky mating instinct got all of us, just like you said it would! Even if we didn’t want to get pregnant, our bodies are designed to, and we just couldn’t help it!”
“That doesn’t make any sense though. Humans can resist the urge to reproduce – that was the entire point of the lecture!”
“That wasn’t what it was about at all!” Megan huffed, disappointed that not even Dr. Jeff understood how important Human Reproduction was. Well, that just meant that he needed to learn too, especially with how strong his own sexual urges must be with all of that dangerous testosterone pumping through his male body. Suddenly, Megan had an idea. “You make recordings of all of your lectures, right Dr. Jeff?”
“Sure, why?”
“Pull it up and I’ll show you.”
At that point Mona interjected. She had been relieved to see that Dr. Jeff clearly had no idea what Megan was talking about, and she had no interest in watching an old biology lecture about sex. “Sorry, but I need to get to class. You two keep trying to get to the bottom of this, and I’ll be back as soon as I can.” She grabbed her books and hurried out.
Meanwhile Jeff was pulling up the video, determined to figure out what on earth had given the students the idea that they needed to go get themselves pregnant. As soon as he started the file, however, his office was filled with an annoying humming sound that he immediately recognized as the annoying noise produced by his broken device. Even so, he quickly grew used to it without even noticing that he had done so, and when his attention snapped to his own voice once the lecture started he was surprised at just how clear and logical his words seemed. If he had been capable of doing so, he likely would have connected his enhanced concentration with his device, but since he was listening this time instead of speaking, all of his attention was completely focused on absorbing as much truth as he could from his own lecture.
The volume on the video was way too high, as it turned out, but Jeff was already far too enraptured to lower it, and the insistent humming sound, along with the accompanying graphic lecture about Human Reproduction, spilled out of his office and into the hallway where the junior and senior bio majors were filtering by. As they did so, however, they were suddenly struck by an irresistible urge to stay and listen, and allow the appealing ideas to sink deeply into their open minds. Soon a small crowd had gathered around Dr. Jeff’s office door as men and women alike inadvertently learned some arousing new truths about their own anatomy and desires.
Megan too felt herself involuntarily sinking back into that soothing state of intense focus brought on by the humming as her new beliefs were reinforced and she became even more certain about the reproductive purpose of her body. It had already succeeded in getting her pregnant, of course, but she still felt her body filling with a renewed interest in sex nonetheless, and idly brought one hand up to cup and fondle her heavy breasts as the other teased down to play with the tingly, well-used hole between her muscular thighs.
A half hour later, Jeff was seeing the pregnant hottie in his office in a whole new light, finally aware of the full strength of his lust for her body as the lecture continued to hum its way into his mind. He now understood exactly how and why she had gotten herself pregnant, and though he was incredibly relieved that he hadn’t been the one to impregnate her, he still felt his body’s deep, unrelenting regret that he hadn’t. Megan was clearly enjoying his gaze and arched her back a bit so he’d be sure to notice her breasts, which had just begun to swell from the pregnancy hormones pumping through her body. Recognizing that she was already bred, Jeff decided to indulge himself a bit and walked around his desk to sit next to her on the couch in the corner of his office, enjoying the closeness of her soft body as the sexy coed lay her head on his shoulder and looked up at him with eyes sparkling with arousal.
Mona arrived back at the office just as the video was ending, and immediately noticed both the odd humming filling the air as well as the crowd of young men and women gathered around the door, just beginning to grope each other, eyes full of shameless lust. Mona wanted to be surprised by the sight, but then she felt her own attention latching onto the words filtering out of the office, and couldn’t prevent herself from coming to a standstill at the back of the group so that she could let those words wrap warmly around her mind and flow through her, leaving her fundamentally changed in their wake. Fortunately, however, the lecture was just wrapping up, and Mona couldn’t discern anything meaningful other than “have a great afternoon”, which she now fully intended to do, of course.
In control of her attention once again, Mona was finally capable of being shocked by the blatant groping of pert breasts and bulging crotches occurring outside the office door before Dr. Jeff’s accidental audience fully gave in to their growing arousal and began to pair off and drift away, the temptation to indulge their powerful mating instincts too strong to resist.
A half hour later a dozen young men were moaning in involuntary bliss as their bodies compelled them to give up their genetic information, and a new group of fertile young female students had been successfully and indiscriminately impregnated.
It was clear to Mona that the video had done something to them, and her fears were confirmed when she walked into the office and saw that Dr. Jeff had moved around the desk and was sitting next to Megan, his fingers tracing tingly patterns along her inner thigh as she cooed encouragingly. What he had to say was even more telling as he turned his attention turned to Mona, and she saw that his expression was a paradoxical mix of lust and helpless resignation.
“I never thought about it that way,” Jeff began slowly, trying to resist the urge to stroke his dick and make himself even more aroused as he felt the instinctive pull of Mona’s petite, feminine figure. “My body really is always trying get me to reproduce. I just assumed that I was older and wiser, more fully in control of myself, but the truth is that I’m just as much a product of evolution as my students are, and my urge to let myself blow my load inside a fertile female is just as strong as anyone else’s. I’d always caught myself checking out my students and colleagues without meaning to, and now I finally fully understand why.”
“I know, Professor. I’ve seen you looking at me before,” Megan giggled impishly. She was clearly no longer bothered by that fact now that she knew first-hand just how strong masculine reproductive urges were. “The first time I heard your lecture, I felt the same way. My body was doing everything it could to get me pregnant, and before I knew it I’d teased Mason’s cock into filling up my pussy with his cum. And it felt so good, just like you said it would!
“Now you finally understand why my getting knocked up is all thanks to you.” she continued, a bit relieved to see that he finally understood her. “And I’m so glad! It’s so important to be aware of just how irresistible our reproductive instincts are!” She opened her legs a bit to give Dr. Jeff’s exploring fingers better access, and began to moan softly when he started stroking her right where she needed it.
Most of Jeff’s attention, however, was still firmly focused on Mona. Since he knew she wasn’t pregnant, all he could think about all of a sudden was how easy it would be to fertilize her young womb. Generally, Jeff wouldn’t be attracted to her thin frame, acne, and angular facial features, but his body knew that cumming inside of her would feel just as good as any other girl, and pass on his genes just as successfully, and so he wanted to anyway. She didn’t seem interested, thankfully, but that didn’t stop Jeff from secretly hoping that the shy young introvert might change her mind. Still, as long as she could keep herself from flirting with him and letting him know that she wanted to mate, they’d both be safe.
All the while Mona stood in the doorway staring in disbelief. “You guys, it’s that video!” Mona finally shouted, interrupting the pair’s horny musings. “Somehow it’s making whoever hears it want to have… sex!”
“Mona,” Jeff said patronizingly. “It’s not the video that’s giving your body its urge to get pregnant – it’s your biology. The video’s only there to make sure you’re aware of it.”
“No, somehow it just makes you think that reproduction is irresistible. Our ability to deny our own impulses is the very thing that makes us human!” Mona insisted. Somehow she just knew that she had to convince them, so that they could all have a great afternoon together.
Megan shared a knowing look with Dr. Jeff. “No, Mona,” she said gently, “It’s been inside of you all of this time. You just need to see the video to realize it.”
“There’s no way I’m watching that video! Dr. Jeff, Megan, I know you can fight this! You have to fight it! Please!”
“You can’t fight biology, Mona,” the professor responded, and Megan nodded sagely in agreement, rubbing her growing belly as if to demonstrate just how true the statement was. Meanwhile Dr. Jeff was leaning back over his desk toward the computer to turn the monitor around and restart the video. “Don’t worry, everything will make sense in just a few minutes.”
“What?? No! I don’t want to become a sex maniac obsessed with getting pregnant!” Mona yelled, grabbing her books and making a break for the door as that seductive hum filled the office once again. Megan quickly stood to block her exit, and before Mona could get past her, Dr. Jeff’s confident voice began playing through the computer’s speakers for a second time. Mona tried to ignore it, but even so she felt her attention sharpening again in spite of herself under the influence of that odd humming, and suddenly all she could think about was how reasonable Dr. Jeff’s words were as he introduced his lecture. She recalled how life-changing this video had been for Megan, and it was so easy to just stand there and listen, so that it would be for her as well. Her struggles slowed, and her arms eventually fell limply to her sides.
“Sorry Mona, but it’s for your own good,” Megan managed to mumble before the humming overpowered her and she helplessly sank back onto the couch to listen to Dr. Jeff once more. God, Dr. Jeff’s hot, she thought to herself. If I weren’t already pregnant, what I wouldn’t let that man’s cum do to my body.
“No, stop! It’s doing something to me!” Mona shouted suddenly, summoning a burst of willpower and clamping her hands against the sides of her head. She wasn’t able to muster the strength to leave the room though, and the voice and the humming were still filtering through her hands into her treasonous ears, allowing the inarguable evolutionary truths of Human Reproduction to begin sinking deeply into her mind.
She glanced back over at Dr. Jeff, who was rubbing his crotch as he continued to admire her feminine figure, and then over at Megan, who was lightly stroking her belly as she gazed lustfully at the professor. Mona knew that neither her best friend nor Dr. Jeff were aware that they’d been brainwashed, so hopefully being aware of the video’s effects would protect her somewhat as she watched her two companions nodding zealously along with the lecture.
But Mona was slowly starting to understand why they were doing so nonetheless. She soon found herself gently nodding along as well in spite of herself, not noticing that her hands had once again fallen to her sides and that she had taken a seat between Dr. Jeff and Megan on the couch. It occurred to her that all of her struggling was making her afternoon less than great, but that just made the idea of relaxing into the couch and enjoying the video that much more enticing.
She still didn’t want the video to do anything to her, of course, and was trying her best to resist, but everything was making so much sense all of a sudden. She knew that she didn’t want to be pregnant, but Dr. Jeff had started talking about all of the ways that her body was secretly trying to get her to impregnate herself anyway, and in the thick haze of that relentless humming Mona was reluctantly realizing that he was right. She could feel herself becoming more aware of the strength of her own sexuality in spite of herself, recalling how natural it had felt to flirt with guys and how her young body had been flooded with pleasure in the rare event that they had flirted back. She now recognized that pleasure as her body tempting her to have sex, to rut like an animal so that she would get herself knocked up like Megan had.
It was what her body was designed for, after all. She had tiny breasts that wanted to catch the attention of a male so that they could be forced to plump up full of milk, and, most importantly, she had a moist pussy that was starting to tingle at the thought of what would happen if it met a cock up close and personal.
The timid nerd blushed at the scandalous thought and shook her head, trying to clear it, but it was no use. She had tried not to listen, but Mona finally had to admit that the video was definitely affecting her anyway, and that she appeared to be helpless to resist. Knowing ahead of time what the recording would do to her had made her aware of the fact that her beliefs were changing, but she could still feel herself becoming more and more certain that her body was designed to get her pregnant nonetheless, and all the while the temptation to treat her body to some risky unprotected sex was growing stronger.
Even now she was already starting to give in to her body’s desires, and was slowly leaning her petite frame toward Dr. Jeff. The video had also effortlessly convinced her that men would be just as unable to resist their own evolutionary urge to flood her with their seed, and she realized that letting Dr. Jeff know about her growing arousal like this would make it that much more likely that the professor would rub his body against hers until his sensitive cock slid into her tight little pussy.
She felt a scarily satisfying tingle run down her spine, and realized that her vagina had begun lubricating itself, just as Dr. Jeff had said it would. She tried to ignore the sensation, still wanting to avoid impregnating herself, but she knew that the sex hormones the video had talked about were continuing to flood her system anyway, increasing her desire for sex still further as her body involuntarily prepared her reproductive tract for mating.
It was all too clear to Mona that her fertile body wanted her to let Dr. Jeff breed her, to make her swell up with his child, and there was nothing Mona could do to prevent it. She found herself inadvertently looking forward to the sensation of her labia parting for Dr. Jeff’s hard cock as it slid deep into her welcoming feminine embrace, knowing that her silky pussy would wrap his phallus in warm waves of compelling sensation that his male body would be completely unable to withstand. His ejaculation reflex would inevitably trigger, Mona’s susceptible womb would be flooded with semen, and that would be that.
Mona knew that she hadn’t always felt this way, and was still fully aware that the video was doing this to her, but by this point she also knew beyond a shadow of a doubt that her body was going to get her pregnant, whether she wanted it to or not. It was funny: she had always assumed she’d never have kids, or would at least wait until after she got a solid job, but now that she recognized how badly her body was trying to get pregnant all the time, she knew she’d never be able to wait that long. And that was even if she was able to resist Dr. Jeff’s advances once the video was over, which was looking less and less likely as he focused more of his attention on her. Meanwhile, that pleasant tingle between her legs only grew stronger with dangerous sexual excitement at his interest, and the petite young woman quickly realized that she was in terrible danger of allowing herself to be impregnated if nobody stopped her.
She just couldn’t help it.
And yet her best friend Megan continued to sit idly next to her, calmly enjoying the unquestionable certainty the video had induced in her as she watched the increasingly aroused couple grow ever closer to coupling. And why shouldn’t they? Megan knew better than anyone just how irresistible the human reproductive instinct was, for both men and women, and she was just glad to be able to watch as the two reluctant lovers finally started to give in to their urges. The hand Megan had stuck between her legs picked up its pace as the interested male began tentatively touching the soft, tempting body of the increasingly receptive female. At this point, mating was practically inevitable.
Thanks to Dr. Jeff, Megan had already known that the sexual urges evolutionarily programmed into her shy friend’s female body were just as strong as her own; Mona just hadn’t realized it yet. And, with the way her cheeks were flushed with arousal as she continued to press herself against Dr. Jeff, it seemed that losing control and getting impregnated was more likely to happen to her sooner rather than later. Megan found herself absent-mindedly nodding along with the lecture again, looking forward to giving birth to Mason’s child, but fully aware that even after she did it likely wouldn’t be long before her hormones and reproductive instincts had her on her back again with legs spread, teasing some lucky guy into pumping her full of even more of that catalyzing cum. She sighed resignedly to herself. It just wasn’t fair how badly women’s bodies wanted to get them pregnant.
After what felt like an eternity the video finally ended and Mona slowly came back to her senses. She didn’t really feel any different, but she knew that Megan and Dr. Jeff had succeeded nonetheless, and that she’d been successfully brainwashed into trying to get herself pregnant, just as Megan had. Even so, all she could think about was how important it was that she know this information, and how good it would feel when she eventually gave in to her fertile body’s reproductive urges and convinced some muscular young stud to slide his cock into her until he came.
The most immediately apparent result of her conditioning was that she couldn’t seem to stop rubbing her body against Dr. Jeff’s next to her on the couch, and even though she didn’t really have any tits to speak of, she still felt herself arching her back to offer them to him anyway. Her knees went weak at the need she could see in his eyes as they locked on to her small chest, and she realized that her flirtations had succeeded. Dr. Jeff’s strong hand firmly gripped her slim hip and slowly slid up her side, taking her tight math team t-shirt with it as it did so and making her nerdy body squirm with desire.
Mona knew she should stop now if she didn’t want to get pregnant, but her body clearly wanted her to continue, and so she gently untucked Dr. Jeff’s shirt from his dress pants in return and began to run her own small hand over the skin of his lightly muscled abdomen. She knew that she wasn’t very conventionally attractive, but the brainwashing seemed to have completely taken care of that problem, both because her testosterone-flooded mate was aroused to the point where he’d slide his sensitive dick into any willing pussy he could find, and because her own new, incredibly uncharacteristic brazenness had caused her to start stroking the startlingly large bulge throbbing at the front of the professor’s pants.
Her body had instinctively known that the stimulation would only fuel his need for the warm, slick embrace of her vagina, and sure enough his eyes hardened and his hands went from slowly making their way up her slim torso to her tiny tits, to gently but firmly pulling her into a standing position so that he could pull down both her long plaid skirt and her loose underwear. Mona’s body rejoiced at being exposed in the middle of his office like this, naked from the waist down, the glistening moisture in her untrimmed pubic hair letting Dr. Jeff know just how ready she was for him to slide into her.
Mona fully recognized that her brainwashed body was flooding her with mating hormones this close to its goal, but she was overwhelmed by the powerful femininity flowing through her nonetheless, suddenly feeling oh-so-receptive to her partner’s advances as she watched him unbuckle his belt. Caught up in the heat of the moment, Mona meekly slid her naked pelvis up onto the desk, both thrilled and anxious about what would happen next; and then Dr. Jeff’s thick, twitching cock finally bounced out into the open, and Mona was torn between feelings of terror and powerful lust at the size of it while Megan gasped with glee from her couch in the corner.
Strangely, though she knew she should also be nervous about what that cock could do to her vulnerable reproductive tract if it got too much stimulation, all Mona could think about was her pussy’s eagerness to feel that monster stretching it out. And so when Dr. Jeff finally approached, Mona simply leaned back and embraced the inevitable, gripping the corner of his desk as her thin legs automatically spread and her pelvis tilted to receive him, shaking with desire as he finally began to slide his cock against her slick entrance.
Jeff certainly had no intention of inseminating anyone today, but his own words had opened his eyes to the truth of his reproductive urges, and now that the head of his cock had made contact with Mona’s soft labia he couldn’t resist the temptation of pressing against her just a bit harder, needing to feel more of his sensitive skin rubbing against hers. Instead, however, he was rewarded with the addicting sensation of Mona’s slick lips enthusiastically parting to welcome him, and his cockhead slipped effortlessly into the tight reproductive tract of the panting female lying on his desk. He paused for a second in surprise at suddenly finding himself enveloped in her silky entrance, while his body rejoiced in the seductive pleasure that washed over him.
“It’s so strange knowing that doing this is so dangerous, and yet my instincts are making me want to do it anyway,” he reflected as his body urged him to slide his cock just a bit further into the mousy twenty year-old’s satisfying pussy.
“That’s easy for you to say,” Mona retorted, but she pressed herself down onto his thick shaft nonetheless, forcing him into her, needing to feel as much of him inside her as possible, and she moaned in equal satisfaction at the knowledge that she was giving in to her own reproductive urges in doing so. When he bottomed out she let his cock sit there twitching against her textured walls for a second before instinct drove her to slowly slide herself off of him, and then her eyes rolled back into her head in ecstasy when he fully thrust himself back inside without warning, driven by his urge to squeeze himself into her tight embrace. And so their dance began.
Unlike Dr. Jeff, Mona fully recognized that her actions were due to the lecture’s programming, but that knowledge couldn’t stop her from letting him slide his rigid, sensitive cock into her over and over again, just as she knew that Megan had with Mason. And all the while Dr. Jeff’s breathing grew heavier as her body continued to stimulate that cock inside her, instinctively knowing that if it did, Mona would inevitably make Dr. Jeff cum, and wouldn’t be able to prevent herself from getting good and knocked up as a result, just like Megan had.
Meanwhile, Jeff continued to marvel at the strength of his own reproductive impulse as he repeatedly thrust between the thin thighs and into the tight, appealing pussy of his fertile young partner, feeling his body growing closer and closer to orgasm as he did so. He didn’t want to get her pregnant, but his body didn’t care. It just wanted to cum, and Jeff knew that if Mona continued to allow him to massage his cock inside of her like this, he wouldn’t be able to resist inseminating her. But, thanks to his own words from just minutes ago, he knew her body wouldn’t let her stop, and that her need to be pregnant would force her to keep teasing his cock until he was forced to ejaculate. Still, he couldn’t deny that her pussy felt great, and that the feeling growing inside his cock felt just as good.
Mona still didn’t want to get pregnant either, of course, but thanks to Megan her brainwashed body certainly did, and she just couldn’t seem to stop using her narrow hips to squeeze Dr. Jeff’s cock back up inside her tight tunnel even as his moans became more insistent and his body began to stiffen. Fully aware of what was about to happen, Mona gave a purr of primal contentment as her playful pussy eagerly enveloped the sensitive head of the bio professor’s cock one final time, and she bit her lip while her dull brown eyes stared intensely into his, urging him to lose control.
The sensation was more than Jeff could take, and his own eyes widened in fateful realization as he thrust himself deeply into her, rewarding his partner with that satisfying feeling of intimate fullness as his cock began to swell and flex with his imminent orgasm.
Jeff felt the urge to climax rising inside of him, and knew that he would be helpless to resist the reflex as the mousy brunette continued to relentlessly stimulate him, clearly lost in the throes of instinct herself. The professor of biology recognized his own evolutionary programming at work as Mona gleefully triggered his ejaculation, and then that seductive tightening sensation was washing over his body, and he found that he was burying himself as deeply inside his partner as he could as his overstimulated cock began to jerk in uncontrollable release. He was fully aware that each blissful throb was sending millions of his sperm frantically swimming for Mona’s eggs with the sole intention of impregnating her and passing his genes on to the next generation, but at this point there was nothing he could do to prevent it.
Human Reproduction certainly is fascinating, he thought deliriously as his body continued to pump hers full of seed. Science never ceases to amaze.
Mona couldn’t help but smile with grim satisfaction at the knowledge that she hadn’t been able to resist her reproductive urges, and that she had successfully stimulated her virile mate to orgasm with her soft, fertile pussy. It had been so easy, and now that it had begun, it couldn’t be stopped. Dr. Jeff’s hips reflexively jerked against her thighs, slapping his pulsing balls against her taint again and again as his body rhythmically expelled his baby juice into the young nerd’s vulnerable womb. Mona could even feel it spurting against her cervix, a slightly uncomfortable sensation that made her realize just how thoroughly she had been brainwashed into impregnating herself, just as Megan had.
It all just seemed so surreal all of a sudden, like there couldn’t possibly be any consequences to what they were doing. Dr. Jeff’s dick jerking inside of her like this just felt so good, so natural. But, now that his generic material was inside of her, Mona knew intellectually that, brainwashed or not, there was nothing she could do to stop it from working it’s potent magic on her fertile body, and soon her trim tummy would begin to swell with life just as Megan’s had. All she could do now was lay back and enjoy the final few throbs of Dr. Jeff’s cock as her body milked every ounce of potent cum it could out of him, flooding her with pleasure to reward her for her risky behavior.
Fully spent, Dr. Jeff slowly slid his deflating member out of the shy young woman. Now that the deed was done he was starting to feel the guilt of his actions, but he knew that with how saturated his body had been with testosterone, there really had been no way to prevent it.
Mona smiled warmly up at her lover to let him that she didn’t blame him for what had happened, even as his seed continued to pool dangerously in her womb. Her body wanted her to be pregnant, after all, just as badly as his had wanted to inseminate her, and they had both very likely succeeded. She only knew, as Dr. Jeff’s DNA began to merge with her own, that other fertile young women needed to know about the dangers of their reproductive urges as well. Hopefully they could somehow avoid allowing themselves to be impregnated by the countless men evolutionarily programmed to get their rocks off inside all of those soft, receptive feminine bodies.
“Dr. Jeff,” the homely young nerd began earnestly as she looked up at her baby daddy. “I need you to believe me when I say that that video really is what’s making us act this way. Of course, now that I’ve been forced to watch it, I also know that you were right, and that my body is constantly trying to get me pregnant. And, thanks to you,” she said with a blush, “I think it’s very likely succeeded.” She allowed herself a second to appreciate the satisfying sliminess of Jeff’s semen, much more viscous than her own natural lubrication, as it slowly seeped out of her and onto the desk. She shivered a bit as the sensation caused her overstimulated pussy to clench in a small aftershock of pleasure, and then continued.
“It’s too late for me now that I’ve already seen it, but we really need to get this video up onto the internet as soon as possible so that everyone can see it. Being aware of this information is important.”
“Regardless of whether you’re right about the video being responsible for our behavior, Mona, I think you’re right about putting it up on the internet,” the biology professor and amateur psychologist said as he enjoyed the view of his half-naked young lover’s body, still in her compromising position on his desk. In fact, her pussy was starting to look awfully good again the way her legs were still spread, keeping her open and inviting… “First, however, I don’t think I’m going to be able to resist sliding back into you. Hopefully just for a minute though, since I don’t want to increase your chances of getting pregnant any higher than they already are.”
Mona giggled from her position flat on her back on top of his desk, unable to suppress her excitement that the sight of her oozing pussy had triggered her mate’s need to fill her with even more of his potent seed. “Ok professor, but I’m definitely making you pay child support if you cum in me again!”
She gasped with pleasure when she felt his rigid cock effortlessly penetrating her once more, knowing all too well that her tight young body would do what came naturally, and that his would do the same.
What a great afternoon.
