Summary:

A lab experiment makes Cabella horny. She needs to be bred and fast, so she takes the train!

Notes:

uhhhh I posted this a bit ago on FA but figured I'd put it here too. of My OC Cabella. She's a scientist. And a Whore. in a good way. Beginning of birth in the end but doesn't happen.

Work Text:

-----
The difficult thing with these types of experiments was that Cabella could never be sure how they'd go. Sometimes documents would give some hints, and it'd be a “One and done,” type of day. Sometimes documentation was less obvious, and it'd be longer. Right now, it'd be the latter.

She needed to use sperm samples in order to impregnate herself in this ritual, one that took pretty quickly, but unfortunately two months later she was still pregnant. Which was a pain, considering she still had to work and research during her gestation time. She grew quickly, so it still fell under the “Rapid” calendar, so long as as she gave birth within a month. After passing into a third month, it'd fall into “excelerated,” something that currently worried her. She hated when they lasted too long, it made it harder to get work done, to meet quotas.

She sighed, rubbing a hand over her stomach. She got off work a couple hours ago, and the most frustrating thing was how unbelievably horny she was. Not every ritual resulting in that, but with her own proclivities it happened more often than not. This particular spell however, did seem to have a stronger effect than just triggering her own kinky side.

She mostly kept to herself at work, her study was considered a bit low brow. People considered she might enjoy it too much, which she did, but that didn't keep it from being perfectly valid. Though she worked alone for the most part, in the break rooms, she couldn't help but notice this particular pregnancy was drawing eyes. Colleagues staring a little longer with flushed cheeks, even one pair of tented trousers seemed to speak volumes to her.

So obviously, she was taking the train home from work, rather than driving herself as usual.

She sighed with annoyance when she got on to an empty train car, she did this for a reason, dammit! Regardless, if she needed to service herself, she would, consequences be damned.

“This might be a symptom,” she thought to herself vaguely, considering this was a bit irrational, even for her, as she lifted her skirt to plunge a finger or two inside of herself. The angle was awkward, her belly at approximately 6-7 months growth, but she made it work anyway. Using her own liquids as lube, she worked at her clit, moaning loudly and without care as she got closer, closer…

Right as she was about to climax, her orgasm disappeared, and she chuffed with frustration. She furiously rubbed at herself, unable to make progress, the angle becoming awkward and orgasm no closer. Her breasts leaked, her nice button up would be frustrating to clean, she hadn't expected the milk from the one to be in yet, ripping her shirt off in frustration between the notion of laundry and desperation to cum.

Thankfully, as the train came to a stop, two people boarded. They both seemed to be fresh out of the gym, one a lean mouse, the other a large bull.

“The fuck?!” One of them exclaimed ,the smaller of the two, and while a brief flash of shame brought a flush to Cabella’s cheeks, arousal was overpowering it. She whined, wiggling her hips at the two men who just boarded, both of them going from shock, disgust, to arousal themselves in seconds. Looking almost possessed, they quickly made their way over to her, boners straining against their pants.

“No way dude, I'm going first,” “Are you kidding me? Get out of the way!” They argued, pushing as each other while Cabella groaned, til the smaller, agile mouse won out on pure speed, unzipped and plunging into her rapidly, immediately setting a brutal pace. He squeezed aggressively at her breasts, seemingly hypnotised as they wobbled and squirted and leaked down her stomach. She threw her head back, yelping as she came, clenching around the anonymous man's prick, who only increased his speed. His balls slapped against her loudly, while the larger man pulled down his shorts, slapping his massive cock against her bouncing, swollen breasts.

“This pregnant whore is insane,” the mouse panted, his stamina surprising Cabella, pussy on fire around the smaller man.

“Would you just fucking cum already so I can have a turn?” The bull growled at him, Cabella’s orgasm still rolled through her, before he shoved his cock in her mouth, settling at least for one wet hole. She moaned around its girth, overwhelmed by sensation.

The mouse pawed brutally at her breasts, rivulets of milk pouring down their sides, Cabella groaned in relief, she hadn’t realized how painfully swollen they were getting. Suddenly his thrusts became more erratic, and he thrust as deeply inside her as he could manage, giving a few last bucks as he did. She moaned around the cock in her mouth, almost feeling as though her stomach was expanding as he pumped cum into her.

The man in her mouth pulled out, cock bobbing deliciously, while he shoved the other guy to the side, wasting no time shoving into Cabella. She shrieked, surprised by his size, seeing as he had to be 3 times the size of the mouse who cum was lubing the way. Her pussy burned, as she pressed back into him, addicted to the feeling. She rubbed her belly, looking closer to 7-8 months now, foggily realizing why this experiment was taking so long. Her breasts seemed to be increasing in size as well, sore, as if the milk pouring from them was being replaced too quickly for her to keep up. The man who just came in her set to that service, suckling at them while she was used like a fleshlight by the other man.

“I bet this slut doesn't even know who the father is,” [i]Incorrect[/i], Cabella thought through the haze, [i]I know exactly who he was and his entire genetic profile[/i], but her cunt still clenched around the thought of an anonymous father. Suddenly, she was empty, and whined extraordinarily loud about it, as the man sat beside her, his dick hard as steel and heavy as he gripped it.

“If you want it so bad, get on top of me,” She obliged, pushing him down with more force than he expected, sinking down on his cock and drinking him in, bouncing at a pace faster than the man below her felt possible. [i]You think [b]you're[/b] in charge here?[/i] Cabella thought, as she used this man as a means to an end. He yelped as she sank her nails into his shoulder, her breasts slapping against her stomach as she pistoned up on down along his length. His cock twitched, she sank her nails deeper.

“Don't you DARE cum yet, I'm not done!” She snarled, the large bull looking a bit nervous now, as he stared up at the canine in throws of euphoria above him. His balls tightened as he groaned loudly, shooting into Cabella as she clenched around him, lucky he got her right across the finish line as he came, her belly rounding out noticeably again. She groaned loudly, suddenly overtaken by a cramp.

Oh no, rationality finally came to her, not here!

Suddenly, the man below her began to move again, cock still shockingly hard and ready for another round.

“Hey, not fair!” Exclaimed her second Paramore, before climbing behind her and shoving her roughly, her stomach pressing hard into the man below her, before he squeezed his smaller cock in beside the second man. She yelped loudly, clenching and twitching hard around them, the stretch brought a tear to her eyes, pain in her lower back mixed with the intense pleasure she was experiencing. Both men began a brutal assault, humping into her cunt at different rates, balls slapping against her clit as she felt a contraction hit

“[i]Fuck[/i], she's drinking me up,”

Both men pumped into her at once, and pulled out as the “ding,” signalling a stop sounded. They both looked surprised, knocked out of their spell, stuffed themselves into their pants, looking embarrassed as they left. Cabella, clamoring out of her seat, and dropped into a deep squat, her skirt hiked up. Cum dripping out of her alongside her waters, the floor soaked with the mess. She pulled at her breasts as a contraction hit her, groaning and hoping to finish up before her next stop, so she could finish writing up her report before she got home.
