Three's A Crowd

Stefanie's father has stood her step-mother Cathy up, claiming that he has to work late. Feeling sorry for her, Stephanie invites her to join her and her boyfriend on their date night. Cathy accepts the invitation and things get heated over dinner and flirty glances. Cathy quickly spices things up by putting the moves on her step-daughter when they're suddenly interrupted by the boyfriend. They say three's a crowd but when everyone gets involved in the hot action - three seems a lot more like company.
