A young, innocent babysitter finds herself in a compromising position as the married couple she's watching leaves her alone with their teenage son. The son, horny and curious, approaches her, and she can't resist his advances. They start kissing, her hands exploring his young, firm body, his hands cupping her breasts. Just as they're about to go further, the husband walks in, catching them red-handed. Instead of being angry, he joins in, turning the babysitter's first threesome into a wild, taboo experience.
