Penny never imagined that her submissive boyfriend, Sam, would ever dare get his little cock near another woman behind her back. So when Penny finds a brand new pair of panties in Sam's drawer that are not in her size she is furious. Sam tries to sputter out an excuse that they were for her but Penny does not listen long before grabbing him by the hair and burying his face in her pantied butt. She tells him that she doesn't believe such a dedicated little ass worshiper like Sam would ever forget what size panties she wore. Either Sam is cheating or... the panties are for him! No matter which is true Penny will not be satisfied until Sam is feminized, totally humiliated, and squealing about how much he "likes to wear girl panties"
