There's an old 80's movie that I'm trying to find out what title. It's a late night teensploitation Cinemax movie. It involves a geek who works at a shop in the beach. He somehow gets some power to be able to hypnotize people to do whatever he wants. There's this buxom blonde whom he wants to seduce, and with the power of his hypnosis, he seduces her. Somehow she ends up making a chocolate cake for him beforehand, and they end up going at it, leaving the cake by the side. For comic reasons the following morning, the cake is smeared on her face. Does anyone know what the name of this movie is?
