Suddenly, the girl's face screws up. "Shit." She mutters, grabbing her stomach. "Hold on. I gotta go pee." She drops the whip on the floor and gives you a seductive smile. "Don't go anywhere, or you'll be a nice pitbull in no time." Then she exits through a door on the far wall, shutting it behind her.
You look down frantically at your stomach and chest. Growing there is a medium-sized patch of white fur. Around the edges, though, it's black. The welts have already faded. You begin to hyperventilate from the pain and the fear. Why is a random stranger torturing you so? You tug on the straps harder and harder. Suddenly, to your great relief, you hear a snapping noise. You look back with wide eyes at your hands and notice that the straps have snapped and they're hanging loosely from your wrists. You tug on your feet restraints and they snap too. This your chance to escape.
You're about to throw your hands up and undo the ball gag when you stop. The only door in here is the one the girl exited out of. If you went that way, she'd surely at least see you. Straining your ears to make sure she's not coming, you leap off the bed and tear open the blinds. Bars, thick, crisscrossed ones, line the window. You scream in frustration and bang your fists on the bars. You close the blinds back up and sit on the bed, hanging your head in your hands. You yell out in shock as you feel like you've sat on something. You look at your rear and notice, to your horror, a small nub of a tail, just starting to form, growing out of your tailbone. You scream into the gag again and tug on the nub, but doing so only causes waves of pain.
"Here I come, my pet!" you hear the girl's voice call. You quickly jump back onto the bed and position your hands and feet exactly as you left them, hoping that the shadows will block the fact that you aren't tied down anymore. The door flies open seconds after you settle and the girl enters, shutting the door behind her. She smiles wickedly and picks up the whip in the corner. "Time for more punishing." She whispers, and saunters over to the bed. She lifts the whip up over her head again, and....
Screaming into the ball, you jump off the bed and tackle the girl to the floor. "AHHHHHH!" she screams. You both hit the floor hard, rolling. You punch her repeatedly as she screams and claws at your face. You shove her towards the door and dive for the whip in the corner. "NO! NO! PLEASE! I-" she screams. You're so blinded by rage that you're deaf to her pleas. You lift the whip over your head and bring it down hard on her stomach. She screams as yellow fur starts growing from the welts. You hastily put your fingers up and undo the gag, throwing it into the corner. Snarling, you bring the whip down again. And again. And again.
The fur sweeps up the girl's body in a wave. She's quiet, as she's passed out from shock. Throwing the whip into the corner, you throw open the door and run out of the room just as you hear the crack of the girl's mouth and nose pushing out into a muzzle.
