He began shrinking as his legs bent up behined him and his arms flexed backwards to attach to his legs. He became much thinner and his body collapsed into itself. He felt a giant hole somewhere in his body.
He saw his mother moving aside his pile of clothes. He wanted to talk to her, but couldn't. He was lifted up, and saw the evil grin on his mother's face. He could hear and see, but couldn't talk or move his body on his own. He was being carried across the hall and into his sister's room.
"Stephanie," his mother said, "I've got a present for you." He felt himself being lifted across the room.
"Oh, thank you Mom!" he heard his sister, Stephanie say, "I'll try it on right now."
Jeff didn't know what was going on, but he felt like his arms and legs were being opened, then closed. There was some kind of weight on his back. He was staring at the floor of his sister's room, but his view suddenly changed and he was looking into a mirrior. He could see his sister's body in the reflection, while she was wearing a bra over her breasts. He didn't know how he knew, but he WAS the bra! A pink bra with a flower pattern over each cup.
"This is perfect!" Stephanie grinned.
"I'm glad you like it," his mother said, "It's your brother, you know."
"Jeff?" Stephanie laughed. She started to rub the outside, "Well, Jeff, after all the time that you picked on me, how embarrasing is it that you're the bra of your little sister?"
