The condom breaks

"Wait...I changed my..." you cry out too late, suddenly panicking as you realize what will happen if the condom doesn't hold. You dig your nails into your friend's back, holding on tight as if that will somehow help the thin, taut material hold out too...it does not. "NOOOOOOOOOOO!" you scream pointlessly as you feel his corrupting cum flood your asshole.

Drew immediately pulls you off his prick and you try to push his seed out of you, but you can already feel your body burning. Your friend puts you back on the couch, trying to calm you, but you can't hear him over the pounding of your heartbeat. You scramble over to the mirror, leaving a shameful trail of slime behind you. You stare wide eyed hoping somehow that you won't see the changes you can already feel. Your body is burning up, too hot to ignore, like your skin is boiling and melting down. Drew is saying something about staying calm, about it even feeling good, but either you're delirious or he is.

It gets worse, like a swarm of hornets stinging your scalp their poison coursing to feed you wild mane of hair. Then your cock is bit by a snake, turning tumescent as it rises in a **** rattle only to vomit up a spurt of sick seed and burn even hotter. Your chest follows next, skin stretching to the point where tearing would be a relief, nipples so full of poison they might explode. Your ass is next, ballooning out humiliatingly and hurting like nothing you ever felt before, your hole feeling like an open wound. The worst was saved for last, bones splinter and shift and stabbing shards of torment **** every inch of your frail, feminine frame. You feel your head spinning down...

into...

darkness...

....

You come to moments later, the most gorgeous creature you have ever seen staring at you with hungry eyes. Still feverish, you reach out to her, and she reaches back, until your newly lengthened fingernails touch the mirror with a CLINK. "EEEEEEEEEEEEEEE!" you let out a high pitched wail of horror, and then grow even more panicked by your alien sounding voice. You start to hyperventilate and Drew rushes over, wrapping his strong, soft arms around you and stroking your hair. His voice is calm and caring, and you want to believe him, but you still see the sexy stranger staring back at you in the mirror and the bimboi bastard that did this to you caressing her.

"...99.99% effective. It says so right on the box. Oh God, Brian. I'm so sorry. I never wanted this for you. I'll do anything I can to help." Drew keeps trying to console you, and the minx in the mirror is all too eager to be comforted. You watch in horror as she leans into his caresses and crushes his curves against your friend's buffer, bigger bimboi body. The ache in your ass grows worse, and you feel a tickle in your throat telling you it wants to get filled again. You can't believe you let yourself get talked into acting so slutty, and now that the outside matches those disgusting urges inside, it's too late to put them back in the bottle.

"I know what you're going through. I was scared too...and shocked...and starving, but I promise you, it does get easier. I can help you, show you how to fight the cravings. Or if you decide you don't want to fight them..." Drew sounds like his concern is genuine, but his body betrays him too, his cock swelling against you which causes your holes to quiver with need. You scamper away, pulling your knees to your chest and backing up against the wall.

You are tempted to trust your friend. He has always been there for you, and he seems to have his cravings more or less under control. He wants to teach you, and you want to very badly to be his student, and that is what scares you. You don't know if you can trust yourself to be alone with the more masculine bimboi. You might be safer running and hiding until you can wrap your head around what has happened.
