Roxie adjusted her webcam and checked herself out one last time. Her outfit for this stream was in keeping with the goth gf aesthetic she had been cultivating: all shades of black and gray, with a skimpy top and a pair of skinny jeans that showed off her best features below the waist: her fat ass, capped by a fluffy white bunny tail; and her gigantic bulge, barely covering her thick, bitch-breaking horsecock. She gave a little kiss to the camera, adjusted the way her hair fell around her long rabbit ears, and clicked “start stream”. 
“Heyyyyy~! Good to see you all again!” she started off, waving to the crowd of names bubbling through chat. “So it’s Friday, and you know what that means…” tapping a button on her keyboard, a heavily edited version of careless whisper began to play, with her giggling as various members of chat bemoaned the return of the song. From the reaction, it was a recurring joke loved and hated in equal measure. “Alright, alright, enough kidding around, let’s get to it - it’s fucktoy friday!” She said, pulling out a box from behind her desk. “This one looks like a lot of fun, you guys. Breeder Corp. recently came out with this line of portal devices and I was picked to demo this pair!” Opening the box revealed a pair of metal discs; one side of each was stamped with the Breeder Corp. logo, while the other was polished smooth. “I know you all love to see my fat dick wreck onaholes on these streams, but I have a pussy too, you know… and who better to fill me up than me~?” By now, Roxie was standing back from the desk, wiggling her hips to accentuate her plump bunny butt. Grinning, she tapped the two discs together and suddenly a pink glow burst from the polished faces. Experimentally poking a finger through one, she gasped when she could see her probing digit emerge from the other. “Oh, cool…” she tapped the finger gently with her free hand, then jerked back. “Woah, that’s a pretty freaky feeling. Well, I’m sure you guys know what comes next~?” 
The chat very much knew what was going to come next, and was eager to show it. Donations started coming fast and furious, asking for all kinds of deviant acts with the new devices. Grinning, Roxie began in her usual manner - a striptease. Hearing the pings of subs and bits come in as she slid her jeans down slowly and sensually did wonders for the ego, and her cock had  noticeably stiffened by the time she discarded her last bit of clothing. The stockings and fingerless gloves could stay, though - she loved how sensual they made her feel. Now, chat could see her endowments fully, and they were already discussing what opportunities the portals would afford. One message in particular caught Roxie’s eye as it slid by. “Can you even fit that inside you?” she read, and then gave a haughty chuckle “Are you questioning the great BunnyBreeder69 on whether she can take a cock?” she dropped the pretentious affect. “I know I’ve been using my dick a lot the last few streams but jeez, the ‘breeder’ part applies to both ends, ya horny dumbasses~” She chuckled, picking up one of the portal discs. Sliding it over her dick, the floppy horsedong slowly emerged from the corresponding portal still resting on her desk. As the half-hard dick drooped slightly under its weight, a new donation appeared on stream.
“Breeder? So then you won’t be using condoms, right?” was all it read. Attached, there was a moderate sum of cash.
“Oh, no condoms? Hmm, what do you guys think?” As expected, a flood of small donations followed, and she giggled delightedly. “Alright, message received. It feels better raw anyways~” She said, stroking her cock to hardness. Fully hard, it reached nearly two feet long, and about the thickness of a coke can even at its narrowest point. Roxy was familiar with its size - she had been showing it off for money on a weekly basis - but this was the first time she had thought about what it might feel like inside her, and suddenly it was more intimidating than it had been before. Intimidating… but also exhilarating. She found her pussy leaking the entire time she was positioning the portal device on her office chair, getting ready to ride her own fat cock. As she finally turned to face the camera and slipped the tip in, the dual pleasure shot through her like lightning. “Ohhhhhh fuck that’s good~” she moaned, trembling slightly but descending no further. She just stewed for a moment in the new sensations. Then, after a moment, she pushed deeper. “Fuck… girls always tell me the flare really scratches the good spots, but I didn’t realize how good it is~” she groaned, bouncing a bit, still only halfway along. “Guhh, I could come just like this…” she groaned, one eye on chat, which soon exploded with messages imploring her to take it to the base. “Haha, alright, gonna go all the way in 3… 2…” before finishing the countdown, she slammed her ass down, letting out a loud smack as her asscheeks clapped against the chair and each other. “Ohhhh… damn, that’s way too good~ knocking up against my fucking womb~” she groaned, trembling from the pleasure. Her pussy was squeezing and milking desperately around her cock, stroking her off without even needing to move. “I should really pull out though, too much more and I might cum inside myself…”
The same account from before returned, this time with an even larger donation. “Cum inside and I double this.” It said simply. Roxie was speechless. She had never gotten a donation that big, and now they were willing to double it if she just let loose inside? Her doctor had warned her about something to do with her genetics being unstable if she ever did something like this, but she wasn’t thinking of that now. Her brain was full of lust - for cock, for pussy, for cum, for cash… It was all too easy to just say yes.
“Fuck it, sure~” She panted, bouncing her hips a bit, moaning with each plunge. “I’m gonna do it~ gonna fill myself up with my own cum~” One hand went to her breast, teasing a nipple as she slammed onto her own cock harder and harder. “Fuck~ way too good~ it’s way too good~!” she cried out, slamming her hips down hard. This was the last that her poor cervix could take, and it opened up to admit her flared head directly into her womb. With an audible pop, she was firmly planted inside, unable to pull out even if she wanted to… and at this point she absolutely did not want to. Her balls clenched, her eyes rolled back, her toe-beans wiggled cutely and Roxie came like a fucking firehose. Rope after rope of dense, hot, thick cum glorped into her womb, causing her stomach to swell with the sheer volume of liquid it was forced to hold. The poor girl was cumming her fucking brains out, cock, balls, and pussy all twitching constantly. The whole affair went on for minutes, the stream chat growing more astonished at the length with each passing moment. After the first minute, the bulge of her belly became obvious, and soon it was a major topic of conversation. Viewers expressed shock and envy at the volume of her cum, at how thoroughly she was getting filled, at the look of utter bliss on her face. Finally, almost fifteen minutes later and with a belly the size of a beachball, Roxie seemed to rejoin reality. Groaning, she shifted and looked down at her belly, gasping in disbelief at the sheer size.
“Oh, fuck… uh, chat, I’m gonna have to cut this one short… that was way more intense than I expected…” she trailed off, watching the discussion scroll by. “Uh… seeyouguysnextweekokaybye!!” she blurted, before darting forward and hitting the End Stream button.
