I looked at myself in the mirror. I saw my own head atop a bizarre body. It had broad shoulders, and well-muscled, masculine-looking arms and legs. I was wearing white panties that conformed to my obviously-empty crotch, and my torso looked like a cartoon with a tiny waist and huge breasts spilling out of it. The weirdest part was that I was getting incredibly turned on. I don't know if it was the way my body looked or the fact that Karyn was dominating and humiliating me, but I was super horny. If I still had a penis, it would have been rock-hard. I thought about how embarrassing that would be, and felt a wave of even greater arousal going down my spine.
"Now, what else shall I do with..."
Karyn was cut off by the sound of a door opening downstairs, followed by her mother's voice calling "Karyn? Are you home?"
"Oh shit!" said Karyn, looking at me.
We heard footsteps coming up the stairs, and Karyn's mother calling her.
"Shit, Karyn, let me change back and get my clothes on!"
"Okay, you can stop concentrating on all those changes," she said. "Hurry up!"
I focused my thoughts on my normal body. I felt things start to change back - I noticed that the panties were uncomfortably tight around my balls as my junk grew back, and then I felt an excruciating pain in my ribs as my body was suddenly crushed by the ridiculously-tight corset.
"Aagh, help me get this thing off!" I whispered, desperately fumbling at the laces.
Karyn reached over and tried untying the corset, but my normalizing body was pulling the knots too tight.
"Shit shit shit!" I whispered.
Suddenly there was a knock at the door. "Karyn? Are you in there? Can I come in?"
I looked around desperately. My clothes were on the floor, and the corset was not coming off. Karyn's mom would flip out if she found me in here fully clothed, never mind if she caught me wearing nothing but panties and a corset. Worse, she would call my parents, and I would never hear the end of it.
"Just a second, Mom!" yelled Karyn, looking in my eyes. "No time for this, Jon!"
Karyn snapped her fingers and whispered, "Concentrate on my cat, Missy!"
I felt the corset loosen and the panties fell off as the image of Karyn's orange cat filled my mind. I looked down and saw the corset growing bigger and bigger around me, then I started to lose my balance. I fell on the floor and caught myself on my hands. I crawled forward right out of the corset.
I looked at my hands. They weren't hands anymore - they were furry paws! I lifted my paw and turned it towards me, flexing what felt like my fingers. A set of razor-sharp claws stretched forth.
I looked around the room. Karyn was huge! She towered over me, looking like she was twenty or thirty feet tall. The room looked huge, too, come to think of it. I leapt out of the way as Karyn frantically kicked my clothes, the corset and the panties under her bed. The door started to open.
"Karyn? What are you doing?" said Karyn's mom, peeking in the door.
"Jeez mom, can't I have some privacy!?" Karyn squealed.
"I'm sorry, dear, I was just worried about you. What's going on?"
"I was just playing with the cat," said Karyn, gesturing at me.
"That's strange," said Karyn's mom. "I just let Missy out a minute ago..."
"She jumped in through the window," Karyn blurted. "I just let her in."
"Oh," said her mom. "Well, let her back out and come down for supper. I brought take-out."
"Okay," said Karyn. "I'll be right down."
The door closed and Karyn picked me up. "Look, you have to go. I think the best way for you to sneak out is looking like Missy - go back to your house, and I'll meet you there later. You can stop concentrating on looking like my cat as soon as you get home."
Karyn carried me over to the window, opened it, and gently set me on the ledge outside. Then she closed the window. Shit! How was I going to get home?
