"I wish I was at Karyn's house." The stone glowed and suddenly Jon disappeared from his room. His eyes were forced closed as an odd vertigo overtook him. A second later his senses told him that up was once again up and his feet were solidly on the floor. Jon made a mental note to use the stone for teleporting only when absolutely necessary.
A muffled groan brought Jon out of his thoughts. He opened his eyes to see that he was in Karyn's room, facing away from the bed. The groan came again from behind him and he spun to find a bizarre scene. Karyn was tied to her bed and gagged while another girl manipulated some sort of vibrating sex toy over Karyn's crotch. The other girl's back was to Jon, she had not heard him arrive and she was very focused on what she was doing.
Jon was instantly glad he decided to wish himself here rather than walking, otherwise he would have been too late. Before he could act Karyn's body went ridged as a squeal escaped her gagged mouth. Her eyes glazed over as her body trembled in post orgasmic bliss.
"Now Karyn " the girl started to say. Jon had to do something!
