You take the hulking rubber creature home with you, placing it on your couch. You look it over, growing harder with every passing moment. You touch it's body, stroking your hand along its massive rubber frame, admiring all the realisticly detailed fur and body parts. It looks like a real life werewolf, albeit made of rubber with bright yellow glass eyes. You work your way down touching the thick penis protruding from his groin, licking your lips for the oncoming night. You stop at his ass though, spotting the gapping rubber asshole between the two tones cheeks. You become curious and compelled to see the depth of the orifice. You shove your index finger deep into the hole. Suddenly the creatures eyes begin to flash bright yellow, causing you to pull back, suprised. But you're not fast enough to escape, because before you know it, the rubbery werewolf has one of its clawed fingers deep into your asshole, causing you too moan loudly, both in pleasure and fear. It slowly retracts the thick digit from your asshole and returns to its lifeless state.
You're start bloated, filled with gas. You let out a giant loud fart ripping through the silence. Another one forces its way out, you being unable to stop it. You feel it this time, a soft pile of shit pushing its way out of your ass, filing up your pants. Unfortunately for you, you now have a werewolf asshole and you're not gonna have much control of your bowels anymore. You don't care though, something's different, you like the shit filling up your pants. You force out a louder fart pushing out a bigger pile, letting it visibly fill your drawers. Your body begins to change, thick muscles and fur covering your body, sharp teeth and claws following suit. By the time you begin to roll around your scat like a puppy enjoying a puddle, Caking your fur with shit ,you look just like the classic Wolfman. By the time you start slurping piles of it into your mouth you look just like the doll that changed you, like a true werewolf.
