"Come on, Jen. Get out of there. I need to use the bathroom," the voice said. It belonged to her Goth sister Zoe.
She opened the door and touched her sister's bare shoulder (she favored black corsets) as she walked out. Then she turned around and caught a glimpse of her "new" brother. He was still Goth, like Zoe, but his clothes were more masculine, meaning a nylon shirt, black leather pants, and black boots. His hair was spiky, though, which was a hairstyle Zoe didn't usually have.
Only after she got back to her room did Jen realize that she didn't have the stone with her. She must have been so wrapped up in trying out her new "ability" that she had forgotten to bring it with her when she left.
Zane lifted the toilet lid and pulled out his penis. As he urinated, his eye noticed something sitting on the floor. It looked like a rock. But why was there a rock in the bathroom?
After he was done, he picked up the rock and looked at it.
