Chapter 7: Cultivating a Fertile Workplace Relationship

Part 6

So, Michelle began staying over at Derek’s place more often, even leaving for work together with him, and she soon had her own corners of his closet and bathroom where she’d started keeping clothes and toiletries.

Amid all the changes as they began their as-yet-undefined relationship, the one thing that remained constant was how often they fucked, though it still was nowhere near often enough to satisfy the inexhaustible sluttiness of Michelle’s pussy.

At first, she was curious about the strength of Derek’s continued desire for her body – now that his sexy dick had done its masculine job and knocked her up with his child, she had expected his carnal interest in her to wane, but if anything, it almost seemed like Derek was more turned on by her now that he had found out that he’d knocked her up.

As they continued fucking, and as Michelle began to show, she began to have an inkling about where all of this lust was coming from, one that also explained some of his earlier behavior as well: it seemed to her that Derek had a bit of a breeding fetish. 

That was fine with Michelle, of course, since she was already obsessed with the idea of getting as many guys’ cum inside her as she could; this just meant that she too now found herself growing hotter and hotter at the idea of getting knocked up on all of that cum and being made to swell and lactate and reproduce.

Her suspicion was confirmed one day a few weeks after beginning to show, starting with the way he stared at her body as she rode him. She mounted him and went to town as she usually did, her slutty pussy milking his cock for all it was worth as his gaze moved between the small bump forming in her petite torso and the areolas just beginning to grow and darken under the influence of her new pregnancy hormones. 

Driven by the Juice as her slutty pussy slowly gripped and squeezed and coaxed his cock, Michelle acted on a hunch and, with the most seductive facial expression she could manage, hefted her tiny, pointy breasts and pointedly told him how tender and heavy and swollen they had been feeling recently. 

Her gambit was immediately rewarded with the sensation of Derek’s body tightening up beneath hers, while his eyes grew wide with unrestrained lust as his gaze locked onto the slight bouncing of her tiny tits and erect nipples from the intensity of her exertions. Derek let out a deep, gutteral moan of release as his body dumped another pleasurable, pulsating load into Michelle’s slutty pussy, and now both lovers’ orgasms were enhanced by the fact that his seed was inside her body, changing her, claiming her womb as his own.

And, with each spurt inside her, with each twitch of Derek’s hips against hers, Michelle felt her boobs bouncing back the tiniest bit bigger, more swollen, more tender, as the Juice molded her body into what Derek clearly wanted, whether he was aware that he wanted it or not.

Derek fell asleep minutes later spooned against Michelle’s smooth skin, his hand clasped possessively – and painfully tightly – around Michelle’s heavy, swollen breast.

It was obvious that the Juice wouldn’t stop there, of course, now that Michelle had an inkling of what was really driving Derek’s lust, and a few days later she felt that pregnant curiosity brewing inside her again while Derek fucked her, and she knew that by the end of the night she’d be different once again.

He was on top this time, leisurely thrusting into her, enjoying both the pleasure her slutty pussy was giving him and the sight of her soft, increasingly pregnant body swelling beneath him.

“I like you like this.”

“What do you like?” she asked playfully, just as unable to resist her Juice-driven yearning for information about Derek’s Perfect Girlfriend as she was her need to fill her slutty pussy. The urge to fill herself with cum was still just as strong today as it had been months ago when Derek had first given it to her.

“I like your wider hips and bigger tits.”

Michelle moaned as she felt herself growing into an even more stereotypical picture of fertility with each of Derek’s thrusts, her new plumped-up tits and birthing hips nicely complementing the noticeable bulge still slowly growing in a tummy that had fully lost its original bony scrawniness. 

Derek kept thrusting heedlessly away into her hungry, slutty pussy for a few seconds, but Michelle felt his pumping growing more and more urgent as she rounded out, until finally his eyes widened as he realized what he was doing to her. But the Juice wasn’t about to let Michelle stop now.

“Mmm, do you like that, my big horny masculine man?” she asked coyly, the curiosity burning brightly within her, forcing her to egg him on until he embraced the lack of filter that came with his growing arousal and spilled his deepest, darkest fantasies along with his seed. This time she wasn’t going to assume – this time he was going to say exactly what he wanted, and she was going to change. “You like the idea of turning me into a swollen, fertile breedslut, don’t you?”

He gave in, just as she’d known he would. “Oh god yes!” he gushed as he got closer and closer inside his baby mama’s juicy pussy. “I want you curvy and breedable, and so fertile that once your womb is free, you can’t help but fill your slutty pussy with the first cock you find and get knocked up again!”

Michelle felt her own orgasm getting close at how hot that idea suddenly seemed to her. She knew the Juice was working within her, changing her, making her womb even more fertile and demanding and breedable. She relished the sensation of Derek sinking his sensitive cock deep inside her insatiable pussy once more, now aware that as soon as her womb was empty again her slutty pussy would immediately begin working to make sure that Derek, or any other guy for that matter, would lose control inside her as soon as possible so that she could get pregnant again. She couldn’t wait.

Michelle felt her mind latching on to a portion of that last thought and found herself suddenly fantasizing about being with other men – with how slutty her pussy was, combined with how there weren’t enough cocks for her in the entire world, in spite of herself Michelle suddenly felt a growing urge to put herself out there more, to get a bit more genetic variety in the cum she filled her slutty pussy with. Even though she was already pregnant, Derek’s words had again and again implied that she was a slut that should be seeking out all cocks, not just his.

Suddenly the thought of going behind Derek’s back once she was fertile again and letting some other horny bull cum inside her and knock her up was more than her curvy, bred body could handle, and she dissolved into throes of mindless orgasmic contractions that squeezed and pulled persuasively at Derek’s stiffening cock. 

“Unggh, here it comes! If you weren’t already a knocked up cumslut you would be now!”

She wrapped her legs around him and pulled him deeply inside as he began spurting, finally giving her slutty pussy what it craved. Michelle loved feeling Derek filling her up like this, though she also knew she’d love any other guy filling her up just as much.

Eventually his spurts began to slow, but Michelle’s pussy continued to burn with lust even after having just been inseminated.
