And then she saw her tail move…
It was a slight motion, just a twitch to the side. But it was enough to tell Jennifer that something was going on.
“Okay…” she stuttered to herself, trying to put the image of a wagging bunny tail out of her head. “This was fun, but they’re probably here and I need to change back."
Jennifer reached back and pulled the tail ... only to receive a shock of pain.
It was stuck fast! She reached around for the strap it was sewn onto and found that it had receded into her skin, leaving only a faint ring-shaped bulge that was rapidly disappearing into her flesh. Her tail flicked as she drew heavy breathes.
More things came to her attention.
Jennifer could feel her body pushing out, muscles tightening and growing. Her feet and legs in particular felt bigger than normal. At first she thought she was hallucinating. But a sharp pain followed with a cacophony of popping joints took that idea right out of her head.
Jennifer dropped down onto the bench in the dressing room, grasping at her socks. Her feet felt smothered by them. The seams on the toes were already frayed and near-shredded when she pulled them off. But no relief came when she saw what her feet looked like.
They were almost twice their original size, longer and leaner. The muscles rippled underneath her taut skin. She could see all the tiny slivers of blonde hair growing out of them, growing out of her legs. She bent forward, perching on her hands and toes as the rest of her body conformed to the new model asserted upon her by whatever magic was in the costume. Her new musculature pulsed with energy as the rest of her body from the waist up bulked up into a curvier, more elegant shape. Her nose felt numb for a few second just before it pushed out into a cute little bunny nose, followed by a set of delicate whiskers.
Jennifer's new nose wrinkled. It was so sensitive. She could pick up the most minute, subtle smells around her. Her bunny ears twitched as she heard another person, a woman by the sound of the footsteps, strolling into the next stall over. The ears on the costume had just about finished merging with her body, with the beginning and end of the change announced by a few seconds of tinnitus. Her teeth ached as the two in front pushed out farther, forming a very subtle overbite that completed the bunny girl image.
When it was over, Jennifer collapsed back on the cushioned bench, quivering, taking deep breaths in and out.
