Chapter 7: Cultivating a Fertile Workplace Relationship (Parts 3-5)

Part 3

These trysts became an almost daily occurrence for the rivals-turned-lovers, and they always ended with Derek enthusiastically planting his seed deep inside his slutty coworker's slim belly as she bent facedown over the counter in front of him, followed by Michelle immediately leaving him the fuck alone.

Derek knew that if they kept sneaking around like this that someone was bound to catch them in the act eventually, but as risky as it all was, and as much as he knew that he should still hate Michelle for all that she'd done to him, he couldn't seem to get enough of her slutty pussy. Once enough time had passed after spending himself inside her, he'd inevitably find himself seeking her out so that he could

thrust

himself into the willing pleasure tunnel between her thin thighs once again.

Still, the risk to his job continued to weigh on him (and as much as he didn't want to admit it, the risk to Michelle's job as well), and so one day, in a moment of oxytocin-induced weakness after carelessly releasing his sperm into her tempting vagina yet again, Derek grabbed Michelle's arm before she had a chance to leave. She struggled a bit, clearly anxious to obey her compulsion to leave him alone, but he pulled her close and impulsively gave her his home address, inviting her to come over to his place that evening.

She looked up at him strangely for a second, and then pulled her arm free and disappeared from the supply closet without a word.

Derek was shocked when Michelle actually showed up that evening, and he gaped at her slutty midriff-bearing crop top and miniskirt. He'd noticed that her outfits at work had become noticeably skimpier and more revealing over the past few weeks, but he'd never expected that this would be how she dressed outside of the office. Derek couldn't remember exactly what he'd said to her while she was under the influence of the Perfect Girlfriend Juice, but apparently some of it had had something to do with being a slut, and Michelle seemed to have taken that part to heart.

Either way, seeing his... enemy? Former enemy? At this point Derek wasn't quite sure what Michelle was to him, but seeing her showing off this much skin on her bony, angular body as she openly advertised her sexuality was making his cock hard as rock. So, he immediately invited her in, bent her over the hallway table without a second thought, and fucked his second load of the day deep into her slutty pussy.

Michelle stood up as soon as he'd finished cumming inside her and, after adjusting her skirt to barely cover her used cocksheath, left immediately without so much as looking at him. She tottered down the front steps on her high heels, enjoying her body thrumming with slutty satisfaction as Derek's thick semen leaked out between her labia.

Derek watched her narrow ass sway from side to side as she quickly strutted away from him down the sidewalk, once again clearly inviting male attention like a common harlot, and he was surprised to find that his dick was already stiffening again at the sight.

Their encounters at work became much more infrequent, but that was only because Michelle was now making her way over to Derek's house every evening after work so they could fuck.

And fuck they did. Soon Derek had taken her on every surface in the house, pumping carelessly away between her legs, dumping endless loads of his creamy spunk into the enticing, insatiable abyss of Michelle's slutty pussy.

And Michelle loved every second. Thanks to Derek and the Perfect Girlfriend Juice, she now craved the sensation of that sensitive cock rubbing directly against her slick vaginal walls, of feeling it flex inside her from the natural stimulation her body was designed to provide. She'd long recognized and resented this fact of her existence, that evolution had carefully crafted her body -- without her consent -- to attract the males around her, to naturally stimulate and pleasure their relentless, horny little cocks, and all so that they could sate that disgusting urge of theirs to fill her body with their genes so that nature could force her to bear their offspring against her will.

Even now she was doing it: fucking a man bareback, unimpeded by a condom or any other form of protection, specifically for the purpose of taking his load right in that slutty pussy of hers as she'd been programmed to.

And she couldn't get enough of it.

Soon, however, Michelle noticed that it was taking Derek longer and longer to start fucking her after she arrived at his place each evening. He fucked her eventually, of course - he always did - and he still took her roughly and with abandon, which she loved, but he also began to preface their sessions by holding her gently, by running his hands up and down her body before ripping her clothes aside and bending her over, and he even began pulling her lips up to his in sensuous kisses before getting started.

All of this confused Michelle. She was only here for sex, which was also what she thought Derek was here for, and with how horny she became whenever the prospect of getting dicked down presented itself, all of this foreplay was unnecessary, and, frankly, a waste of her time.

Even more unexpectedly, however, the genuine pleasure she'd begun to feel when getting fucked by Derek was only intensifying, and it was getting to the point where she'd had to start distracting herself from her own arousal so that she could focus on getting Derek to blow his load inside her as quickly as possible.

All of this confusion and unexpected pleasure came to a head the first time they finally fucked in Derek's bed. Michelle had stripped off the slutty shorts she was wearing that day and had rolled over onto her knees, presenting her dripping pussy to Derek so that he could do her doggystyle while she was facedown like she was supposed to be, but he stopped himself before sliding his cock in and told her to turn over. She obeyed, but being forced to constantly look up into his face like this, in addition to being awkward and disconcerting, felt deeply... wrong somehow. So, the Perfect Girlfriend Juice made her ask "Why?"

"I want to see your face."

"Why?"

"Because I want to see you enjoying yourself."

"Oh."

Again Michelle was confused. This made no sense; since Derek only saw her as a willing, fertile outlet for his reproductive urges there was no reason for him to care anything about her pleasure, much less actually enjoy it. Plus, he had specifically told her -

programmed

her even - to face away from him while he used her, ostensibly to make the inherently passionate nature of their semen transfer sessions feel less personal, or maybe so that he could ignore the fact that he was subconsciously trying to procreate with his most hated enemy.

There was only one easy explanation for this new development: Derek must be such a narcissist that he was now getting off on the idea that Michelle could genuinely enjoy having sex with him - aside from her Juice-induced need to fill her slutty pussy with cock, of course - and he now wanted to see that confirmation of his fragile masculinity reflected in his longtime enemy's face.

By this point Michelle couldn't deny that she somehow

had

begun to genuinely enjoy sex with Derek, but she still appreciated the deniability and separation that facing away from him gave her. After all, other than her need to let Derek impregnate her so that she could finally become his Perfect Girlfriend and be free of his influence, she really didn't care who it was back there pounding his jizz into her slutty pussy.

Regardless of the reason for the shift in Derek's preferences, however, the Perfect Girlfriend Juice made sure that Michelle paid close attention to each of these little hints about his inclinations, and so she now found herself staring up into Derek's uncomfortably intense visage as he drove his cock into her pussy missionary-style, her face flushing with heat now that she was forced to recognize and enjoy her growing arousal, and it wasn't long before the inevitable happened.

Derek made Michelle cum.

Hard

.

Derek had been taking his time fucking her for a while now, to Michelle's chagrin. Not that his need for her body had decreased at all - if anything, it had only gotten stronger - but as Derek spent more time inside her, and as he explored the hard angles and small, soft curves of her body, he began to get a feel for what she liked. The signs were subtle, but they were there, and for some reason Derek really enjoyed learning to evoke those small reactions from Michelle until he could play her body like a finely-tuned instrument.

Things were a bit different with Michelle facing him like this, with her soft, slim abdomen against his abs and her small breasts in his face, but Derek put what he had learned to work anyway as he thrust himself inside, his fingers playing across her body, eliciting tightness and tingles and tickles and a pair of painfully stiff nipples that ached to be pinched, and within minutes Michelle was staring up into his eyes with cheeks and lips flushed with obvious arousal.

All of this still felt like a waste of time to Michelle, but regardless of how she felt about it, her body was responding to Derek's touch, and in the background was the constant rhythmic stimulation of his cock rubbing against an especially sensitive spot on the front wall of Michelle's vagina that threatened to overwhelm her with sensation. Once again Michelle began to feel the familiar, pleasurable pressure building up inside her torso that had been growing more and more intense during each of her sessions with Derek over the past few weeks.

This time, however, she wasn't allowed to ignore it, and was instead forced to embrace that tension building within her, that growing, involuntary urge for release that had Michelle's lips automatically parting in a needy whimper as she focused on the heat that pounding cock was stoking within her body. The sensation was quickly building toward a peak, and Michelle didn't think she'd be able to contain it much longer.

Watching Michelle respond so strongly to his efforts was significantly hotter than Derek had expected, and each stroke inside her tight pussy to drive her arousal higher added a corresponding degree of insistency to his own urge to cum.

Michelle could see in Derek's eyes that he was close to losing control inside her, and so she redoubled her own efforts, rolling her hips to meet Derek's thrusts, needing that cum inside her slutty pussy as soon as she could trigger his body to release it.

Derek answered with equal force, pounding himself into her even as her slick walls twisting and twining around his shaft caused his balls to begin to tighten. Still, he'd noticed that Michelle liked it especially rough when he was about to blow, that she got off on feeling properly

used

as he was losing control inside her, and though he hadn't yet been able to fully capitalize on that knowledge, he somehow knew that this time things would be different.

"Here it comes!" He yelled as he slammed himself into her one final time, the tip of his cock lightly brushing against her cervix even as the pressure building inside Michelle became unbearable and her own dam began to burst. Rather than dampen her pleasure, however, something about the sharp discomfort of having Derek so deeply inside her, of feeling his cock swelling directly against the gateway to her unprotected womb as it prepared to release a torrent of his pent-up sperm into her, drove her absolutely crazy. The intensity of her incipient orgasm skyrocketed; she was forced to focus on the sensation as her entire body began to tense up, and then Michelle had no choice but to let Derek see what he had done to her as her jaw dropped open and she began to scream his name in ecstasy.

All the while, Michelle knew deep down that she was supposed to be focusing her attention on getting Derek to cum in her slutty pussy, but her amygdala and hippocampus were literally short-circuiting at the moment, and all she could do was helplessly ride out the spasms of pleasure that had begun to surge through her body. Luckily each mindless clench of her pelvic muscles also caused her vaginal walls to tightly squeeze Derek's cock in their slick grip, and the pulsing pressure around his already overstimulated cock got Michelle's slutty pussy exactly what it wanted anyway.

Derek frowned down into Michelle's pleasure-addled face as his cock stiffened past the point of no return deep inside her, and he let out a primal masculine growl at the intensity of the climax that Michelle's clenching pussy had triggered. He thrust as deeply into her as he could, and then he began to experience his own set of incredibly pleasurable involuntary contractions; the difference being, of course, that his enjoyable spasms were emptying the contents of his balls into a thickening pool of DNA at the entrance to Michelle's uterus, effectively flooding her mindless baby factory with the compelling blueprints for his own babies.

As she continued to convulse, it occurred to Michelle that she had never cum from having a cock in her pussy before - no guy had ever seemed interested in putting in the effort - but now every bit of her ecstasy was clearly written on her body for Derek to read as he came deep inside her face to face for the first time.

Unfortunately, Michelle's opportunity to take a minute to recover from her mind-shattering orgasm was precluded by her automatic need to leave Derek the fuck alone now that he had cum inside her, and so she immediately scrambled to get out of bed so that she could pull her revealing clothes back over her naked body and leave.

Derek caught her arm for a second time, however, this time before she could fully leave the comfort of the bed.

"You, uh, you don't have to leave right now if you don't want to."

Once again Michelle was filled with confusion even as she sank back into the covers and relaxed into the post-orgasm oxytocin flooding her body. She

did

still want to leave; now that they'd had their meaningless, unprotected sex she was eager to get away from Derek as quickly as possible, because that's what he told her that he wanted her to do.

But from the way he had phrased his comment, it now clearly seemed like he wanted her to stay for some reason, and if Derek wanted her to stay, the Perfect Girlfriend Juice coursing through her veins would of course make sure that she stayed.

He must just want to cuddle for a bit

, Michelle concluded, and a sudden, unexpected warmth for Derek immediately began growing inside her that caused her to unconsciously curl her body against his. But then she immediately thought of another, much more likely reason for his asking her to stay: he wanted her to wait so that he could fuck her slutty pussy again. Well that was perfectly fine with her; he had made her perpetually horny for dick, after all.

Derek was enjoying the contact with Michelle's bony body more than he'd expected as they spooned together on the bed. He was nice and mellow from getting his rocks off, and Michelle's soft skin and naked curves felt surprisingly pleasant against his chest and thighs. Her hair smelled nice.

After a few minutes of laying like this, however, Derek's refractory period ended, and the feel of Michelle's naked body and the nearness of the slutty pussy between her legs began having its natural effect on him again.

Michelle immediately noticed Derek's cock beginning to press against her ass as soon as it began to stiffen, and she moaned with unquenchable need and began wiggling her butt to encourage his member to rise faster. She needed that cock inside her where it belonged as fast as possible so that she could take his load right in that slutty pussy of hers. There weren't enough cocks in the world to satisfy her.

I

knew

that he only wanted me to stay so he could fuck me again

, she thought smugly to herself. Still, for some reason Michelle's internal assessment of Derek's motivations didn't carry quite the vitriol that they usually did.

Derek was more than willing to oblige Michelle's need for cock, and she felt him shift his body a bit lower along her thighs so that his erect dick could slip through her slick thigh gap and nestle against her soaked entrance. Michelle pressed her ass backwards so that he could slide effortlessly into her slutty pussy again, and Derek noted the extra-slick sensation that his semen added to her natural lubrication as he began the now-familiar ritual of thrusting himself toward orgasm inside her.

Michelle was relieved to feel him filling up her pussy from the rear this time. Something about this position just felt more natural to her for some reason, and the sensation of being taken from behind like this -- so similar to that first evening when she'd been lying facedown across his desk with a load of his cum in her unprotected pussy -- soon had her squirming with pleasure once again. She was forced by the Juice to recall that Derek wanted to see the pleasure in her face, however, and so Michelle turned her head back over her shoulder so that he could see clearly as the intensity of being taken from behind soon had her engine revving again.

Derek was still a bit surprised at just how much he seemed to get off on Michelle's pleasure, and even though he had just cum a few minutes before, the sight of her biting her lip in clear rapture, combined with the sensation of her hips bucking against his dick as he squeezed himself into her tight entrance over and over again, soon had the remaining semen in his balls readying itself for release as well.

Now that the taboo of allowing herself to orgasm in front of Derek had been broken, Michelle again screamed in ecstasy and clamped her pussy down on his cock like a vise once she realized that his load was coming, needing to feel it warm and raw inside her, soaking into her womb, catalyzing the change inside her body that would finally fulfil her obligation to Derek and let her go get her slutty pussy stuffed with cum as often as she wanted.

Derek flopped back onto his pillow once he had finished filling her up again, sweaty and exhausted from his reproductive efforts. Michelle thought that he seemed spent for the night, and her suspicions were confirmed when he drifted off into unconsciousness moments later. Instead of immediately leaving, however, she was surprised to find herself curling up against his body once more, and before she knew it she had fallen asleep in his arms.

When Derek woke up the next morning Michelle was already gone, and he shocked himself with the realization that he might actually miss his irritating coworker. Just a little.

Part 4

Life continued like this for the next few weeks, first with Derek fucking Michelle hard each night until she came and then blowing his load inside her, and then with Michelle staying the night but leaving before Derek woke up.

In between their frequent copulation, however, Derek found himself talking to his new fuckbuddy in a way that he would never have thought possible just a month ago. And, whether it was bonding hormones or the Perfect Girlfriend Juice, Michelle seemed unexpectedly willing to open up a bit herself as well.
