Roxie gazed at the Start Stream button nervously, rethinking her decisions. She still had time to back out, time to find something else for this stream… but her throbbing cock made it clear this was going to happen - it made her too horny to not go through with it. She steeled her resolve and clicked the button. 
“Hey guys! It’s friday again, and you know what that means~” she was putting up her usual persona, but nerves had crept into her voice. “O- okay, so, today’s fucktoy… umm…” she wiggled slightly in her chair, hands shaking. The chat seemed a bit confused at her uncharacteristic hesitance. 
“Oh, fuck it, let’s just do this!” she finally said, reaching below the desk and lifting up a cute little baby bunny. This was no ordinary bun, however - she looked almost identical in patterning to Roxie herself. But that was by far not the most striking feature she possessed - those would be her massive, milk-leaking tits and gigantic fluffy ass! The little baby wriggled slightly as she was held, gurgling cutely. This got a reaction - some disgusted, but mostly adoring how cute the newborn looked. What Roxie said next took them all off guard, however.
“Today’s fucktoy… today’s fucktoy is going to be my own slutty baby daughter~! I knocked myself up and now I’m gonna fuck my inbred baby like those onaholes I use every week~!” At this, the chat really got into it! Donations eagerly looking to see all the details of this new “fucktoy” began to roll in. Ever the obliging host, Roxie squeezed the day-old baby’s tits, inciting a cute babbling moan and splashing a bit of milk onto the camera. Then, turning her daughter around, she bent the girl over and spread her ass to show off a tiny bun donut and constantly leaking infant pussy~ Donations started to arrive faster than ever, the chat exploding with calls to just get to it, begging Roxie to fuck her already. Her pulsing cock could just barely be seen on stream and she was nearly drooling over the new fucktoy - a constant stream of precum leaked from her cock, and eventually she couldn’t hold back any longer.
“Okay chat, here goes!” She said excitedly, all her nerves having melted away with her lust. Plopping her thick ass down in her chair once more, Roxie lifted the tiny tot up high to position that dripping pussy against her flared head~ it was a sight not unfamiliar to regular viewers, but for the fact that this time, rather than the latest onahole, she was holding her own inbred daughter!
“3… 2…” she counted down, but as before, didn’t bother to wait and finish~! Slamming the baby down in one smooth motion, she nearly came on the spot~ Her back arched as she flexed her paws to keep herself together, and the chat went wild, never having seen such a strong reaction from their favorite toy reviewer!~ the clear bulge in her daughter’s belly showed off every detail of the throbbing, pulsing horse cock, prompting all manner of perverse comments, with viewers wishing they were her and her daughter in equal measure~ “O-Oh my fucking god g-guys~” she spoke through gritted teeth and body shivers “T-This is the greatest thing I-I’ve ever felt~ she’s clamped down on my cock better than any toy i’ve ever used!~ Her womb is so fucking tight~” She was still trying to review, even in the midst of her most depraved stream yet~ 
The news of this debauched stream had clearly gone viral - her chat was blowing up, the most popular stream on the website, with over a million active viewers~ in the last 10 minutes alone, she had received enough donations to keep her whole life running for a whole year~ But Roxie wasn't able to think about any of that as she began to slide her toy up and down her cock, feeling the tight pussy slip on and off her medial ring~ With each pop in and out of the hungry baby womb, it felt like the cervix was kissing her flare, begging her for that hot, thick, extremely fertile jizz that she had packed into her balls… Were they a bit bigger than last time?
“F-fuckkk~ you guyyyys~ it’s way too good~ my dick almost feels like it’s growing~” She moaned, pumping her baby like a cheap cocksleeve. The chat yelled the truth at her - it didn’t feel like she was growing, she was! The bulge of her hyper-sized horsedick was getting larger and larger with each thrust!
Roxie pushed her baby fucksleeve face-down into her desk to get closer to the screen and read what was scrolling by. Her hips didn’t stop, however, continuing to pound the tiny slut as she read the stream of messages. “B-Bigger? R-Really? Oh, fuck~ this must be from those pills that Breeder Corp sent!”
A message from that same mysterious account arrived, again with a huge donation. “You’ll grow every time you fuck one of your babies… and a bonus each time you knock one up! The more inbred, the bigger you’ll get! Enjoy!” She read the message once, then, in disbelief, read it again… and again! Continuing to thrust the whole time, the combination of the thought of endless growth and the feeling of the best pussy she’d ever fucked meant she couldn’t last long~ her nuts had started to churn and clench, as she could feel herself cum~ deep inside her baby’s womb, her cock flexed and spewed her thick, extremely fertile seed~ her knees buckled under her and she clung to the desk as the stream caught the magical moment as the infant was knocked up~ every second another wave of cum inflated her tiny womb, but the real growth was in Roxie~ her nuts immediately doubled in size, and her cock slid out another 6 inches from her sheath~ All of this only increased the amount of cum blasting from the end of her cock, filling the tiny baby womb more and more. Just last week she had cum enough to inflate her own belly to the size of a beachball - the cute little fucksleeve on her cock was already past that, with no signs of stopping~! Gallon after gallon filled the girl, until she could rest comfortably at desk height supported only by her massive, cumflated belly~! Finally, with the last dregs of orgasm draining into the little cum-balloon that was her daughter, Roxie pulled out and smiled at the camera, throwing up a peace sign and showing off her conquest. “Ahhh~ well, time to give this fucktoy a grade… A+++!” she giggled, her cock still leaking cum, her baby’s pussy overflowing with the remnants of her gigantic orgasm. “Highly recommended! Go fuck your babies today~!” she said playfully. The chat was already flooded with people saying they had already started to do just that; Roxie shivered as she imagined all the horny mothers out there pounding their baby girls, all because of her~ “I think I'm gonna need a larger space…” She muttered to herself as she looked over her masterpiece. “Well, that’s it for this week, guys~! See you next Friday… and don’t worry, there’s gonna be plenty more of this from now on~” She waved to the camera, gave the crowd one last good look at her daughter, and clicked End Stream.
