Zoe listened to the moans and screams coming from her brother's room. "Damn it!" she thought. "Jon gets girl after girl just lining up to be fucked by Karyn. It's not fair! Why couldn't I have been the one with the dick that drives everyone wild?" She had peeked out of her room and seen Sarah McMillan (SARAH MCMILLAN for fuck's sake!) the queen of the school's social hierarchy leading Jon into his bedroom with her hand grasped firmly around Karyn. "It isn't fair!" she screamed as she walked towards the bathroom. Just as she reached for the door knob, the door flew open and stranding in front of her was Sarah, dressed only in Jon's bath robe.
"Oh Hi, uh, Zoe, right?" Sarah stammered as she came face-to-face with her lover's sister. "I was just, uh, stopping by to use the bathroom and, well, I needed to use your brother's robe... Um bye!" With that, Sarah left the room and headed down the hall. Zoe entered the bathroom and locked the door. She immediately started a tantrum, knocking the dish of bath soaps off the counter, throwing the tooth brushes into the sink, opening the vanity and throwing everything out onto the counter, and finally pulling all of the towels out of the linen closet onto the floor.
It was then she saw a strange stone lying on the floor. She picked it up, and inspected it for a moment, but was still too hurt and jealous to really pay attention to it. "Damn you, Jon," she said. "Why is it that you always get to have everyone lining up to fuck you and I am left all alone? It's Karyn, that's why! If I had a hot girl as my vag like you had one for your dick I would be having everyone lining up to fuck me too," she said with tears in her eyes. "I wish I had Sarah as my pussy like Jon has Karyn as his dick," she cried while holding the stone.
Jon looked up and saw Sarah begin to open the door to his room. "Hey there, lover. Ready for round two?" she asked, when suddenly there was a flash and suddenly she was gone. Jon's was left looking at the empty doorway where Sarah once stood. "What the fuck happened to her?" he wondered. "Oh no! The stone!" He immediately jumped up and, with Karyn swinging asleep between his legs, ran to the bathroom, hoping to somehow stopped what he knew had already happened.
As he approached the door to the bathroom, he found it unlocked. He slow turned the knob and peeked inside. When he looked in, he was shocked at what he saw. His sister was fingering herself, only it wasn't her vagina she was stuffing her fingers into, it was and exact copy of Sarah McMillan's face between her legs! As Zoe shoved three of her fingers into Sarah's mouth, Sarah kept moaning louder. Jon stood in stunned silence until Zoe looked up and saw him. "Jon!" she shrieked. "I was, um, just um .. don't you fucking knock?!" she yelled while wrapping a towel around her waist and storming out of the bathroom and marching down the hall towards her room.
Jon walked up and picked up the forgotten stone which Zoe left behind and said "I wish I knew what happened to Zoe." In an instant, Jon knew what had happened. When Zoe wished to have Sarah as her vagina just as Jon had Karyn for his penis, the stone told him, Sarah was instantly transformed into Zoe's pussy but since she wished for it to be just like Karyn was Jon's penis, the stone had interpreted it as Jon's previous wish and only Jon knew that Sarah had been transformed.
"Fuck," he though. "Now Karyn is my dick and Sarah McMillan is Zoe's pussy. Well at least it is only for a week I hope."
