Balros & Echoen
Echoen settles in to relax, unwind, decompress. The fact that it's in the family home of a den of bunnies is beside the point. The naked herm bat slouches on a couch and flips on the TV to a hyperherm basketball game, ignoring the petulant protests of the oldest daughterbun. Except when you pick up the phone to call for help; shi casually speaks, not even looking away from the show. "If you call the cops, they'll find out about how horny you are for your sisters. What would they say about a girl like you, hitting hyper-puberty?" With every syllable, you can feel your shorts bulging forward, a fat log of pulsing flesh snaking down against your thigh, balls fattening and creaking with seed, chest puffing forward with full and fat breasts. Your younger sisters whimper as they look on from the hallway, their wiggling noses filling with your fresh needful fuckscent.

The receiver shakes in her paw as your words wash over her, and parts of her both new and preexisting swell and throb, each of which NEED attention! You get through into her mind, too, and once you've finished speaking she looks to her sisters, and then back at you, looking confused.
"Why? Is there something wrong with that?"
The brightest-blushing bunsister gives out a tiny whimper, gripping her skirt and locking her legs together in an effort to resist the urge to give in, but that was enough of a mistake. In an instant, the newly-hermified bun strides across the room, picks up her neediest of sisters (already being twice her height) and begins using her as a squealing, wriggling fucktoy. You're treated to the view of a large bunny's back as she's squatting and visciously using one of her former family; her shorts straining more and more as two buttcheeks and a massive nutsack surge larger and larger.

There's all these little ways in which the bat's corruption also takes hold - such as one, then two, extra fingers gently pushing out from your palm to grip the phone receiver and make it steady, the new nerves and muscles making your arms tingle. The light puffs of pheremones that drift like pink mist from your fur or collect like dew. The bat chrrumbles pleasantly as shi hears just the tone of your voice shift from petulant to incredulous, a bunbun's entire personality being mutated into something greater. You stride across the room in front of the TV, giving the bat a glimpse of your curvy and sweaty body and the bouncing bulge in your groin and atop your chest. Shi lowers the TV volume and shifts hir posture to see both it and you as you pick up your sister, one of a couple, and remorselessly FUCK her in front of all the others. The sight, sounds and scent stirs the bat's sheath to swell, and shi drifts a hand across hir rising pillar of black fuckflesh.
"Yes, then I wouldn't have all of you to myself. Bring them over here, I can smell them going into heat."

The bunnygirl you're fucking, at first, squealed loudly as she was fucked, filled and violated. But rapidly her own body began to corrupt like yours, breasts and belly expanding as you flooded her with cum and pistoning fuckmotions. Her squeals briefly quieted as her head began to bisect, slowly dividing into two bunnygirl faces, sharing the same middle eye. Looking up at you in mingled fear and lust. Her second muzzle crying, her first muzzle whispering louder and louder her lustful sins and needs. When her head completely -pops- into two heads, she clenches her thickening thighs and legs around your hips to ride you hard.

Despite the screams and squealings and whines of her new fucktoy, your calm and logical words still reach her ears as if there were no other sounds at all. Your command makes her stop and turn around, sister still speared on her prick, held up by the strength of her erection alone.
The speared sister's head bisects into two, of wildly different emotions, while suspended like that, and begins needily riding her dom-bun as she's walking, second sister held underarm, over to you.
Muscles spasm and grow upon your main target's body as she moves over to you; her whole frame henchifying up until her frame suits that of a bouncer's... and then she leans over you on the couch, her expression dumb but compliant, staring deep into you as if searching for the next command within your swirling, ethereal gaze... and completely oblivious to the sister who's been shoved between us, both heads screaming (despite one of them being in utter fear) as the combination of being fucked and being in contact with you makes her belly push forward again and again as her ovaries swell and produce, a new bun forming second by second.

What a pleasant sight you make, standing in the hallway with your mutating sister impaled on your dick, your balls pulsing fatter even as you cum and cum and cum into her. The bat's towering spire throbs to full mast as you scoop up your second sister and begin to walk over to hir, pacifying the wriggling bun by making her grow a second set of eyes atop her first, two brains conflicted with hormones and emotion to coordinate any escape from you. Your inflating muscles and athletic build coax a squirt of precum that makes hir dick shine as you approach; your gaze all hormones and dumb need. Your huge arms and hands easily gripsqueeze your second sister and shove her against the bat's body, causing Echoen to groan in pleasure as the mere physical contact is enough to set her off with overwhelming growth. Shi lifts hir pre-smeared hand off hir cock to stroke it across your sister's bloating belly, then scoop hir closer, pushing the bunbun between hir breasts, positioned fattening-ass above hir dark dick. Shi makes no move to fuck her or even more hir hips; the growing breedbunny squeals as her pussy spreads, parting as she gives birth to her first daughter, forcing her down onto the bat's throbbing boner. The daughter blinks, slick with juices, looking up at 'mommy' and realizing that she's the same person and insanity wasn't an escape. Both of her hot bodies begin to fatten with pregnancy again, her twin pairs of eyes on each head looking at her double-headed sister stuffed onto your meaty cock.
