Revenge

She reached into her purse, and was about to pull out the medallion when a thought struck her.
"Wait just a moment Matt darling" she purred as seductively as she could.
Then exiting the stall she went back out into the club, where she found Lisa sitting waiting, Nick went over to her, and while she wasn't looking took her jacket from off the seat where Lisa had lain it. She went quicly back to the stall where an expectant Matt was still waiting.
Nick pulled out the medallion, and started to seduce Matt, pretending to try and Hypnotise him. Mid way through she was able to press the medalion and jacket againt him. Nick watched in satification as a startled Matt started to change before her eyes. Grabing the medalion back, she quickly exited, chortling at the thought of Matt being trapped as Lisa's double. That would teach him to steal her girlfriend.
