Chad looked up and saw Kim, the girl he had a big crush on at school. She was with a few of her friends. He couldn't let her see him like this. What would she think?
He ducked into the changing rooms at the back of the store. He peaked out the curtain, and saw the girls approaching.
"Look at this weird shit! What kind of freak would wear one of these!" said one of Kim's friends. Kim nodded slowly.
Crap, he thought. I don't want her to see me. She will never talk to me again. But I can't hide here forever. That saleswoman will come looking for me. Maybe I can slip into a bodysuit and sneak out.
He looked around the changing room. The only bodysuit he could see was some furry looking ratty costume on the floor. It looked like some kind of bizarre dog. He held it up tentatively. Was he really going to do this?
"What's back here?" said a voice, just outside the changing room.
He had no time. He quickly started to slip the suit on. It hung limply on his body.
"I thought they adjusted to fit your body, " he mumbled.
"You have to take off your clothes first, numb nuts " said a voice.
Chad was startled and looked around. But he couldn't see anyone.
"Can I help you ladies?" said the saleswoman outside the door.
It must have been her. She must have been talking to the girls, Chad thought. A lucky break at last.
He slipped off his clothes, and slipped into the costume. This time as his bare feet slipped into the costume it seemed to inflate around him. He rose off the ground as he got a little taller and bigger. As the costume reached his neck two large canine heads flipped up on his shoulders, and rapidly inflated. The right head yawned, stretching its mouth.
"Aw, finally. Someone finally had the nerve to try us on. Wake up, idiot," said the right head.
The left head yawned sleepily. "What? Is it morning already, Mindy?"
"Wait. What is going on? This isn't what I wanted," said Chad, as the middle canine head wrapped around his own.
"Relax, kid. This is all part of the process. Don't worry. We'll take care of everything. Ole Mindy and Cindy are here to look out for you," said Mindy, the right head.
Chad felt his jaw stretching to fill the muzzle. His teeth ached as they stretched into long canine teeth. His tongue grew longer and lapped out of his mouth. He blinked, as his eyes became canine. His new long ears twitched on the top of his head.
"There, see. No problem at all," said Mindy.
"Yea, we are free again," said Cindy.
Chad cleared his throat. "What's going on? Why do I have three heads?" His voice sounded strange. Deeper, but higher at the same time.
"You don't know? Didn't you pick this bodysuit?" asked Cindy.
"Relax, kid. This is completely normal. All part of the Cerberus bodysuit," said Mindy.
"Cerberus? As in that three-headed dog?" asked Chad. "Why are you female?"
Cindy and Mindy chuckled. "We aren't the only ones. Cerberus is female, and now so are you. Have a look for yourself, " said Mindy.
Chad looked down and saw two large breasts covered by dark black fur. He reached down with a clawed hand and felt an emptiness in the groin. A hole where his dick should be. He reached inside, trying to find his dick. But all he felt was sensitive warm flesh. Cindy cooed.
"That was good. Do it again. It has been so long, " said Cindy.
Chad was beginning to panic. He had to get out of this weird suit. And soon.
