Aerobics Instructor Loses Control

An aerobics teacher is trying to demonstrate a fitness routine, but she finds herself making involuntary movements which draw attention to her ass. Perhaps it has something to do with the strange spiral videos a fan has been sending her .. She tries to pass off her movements as part of the routine, but they become more and more exaggerated until she is finally frozen in front of the camera with her back arched and ass on display.
