Melody Marks, a petite Latina student, struggles with her partner, Paul Strong, in a cramped apartment. Their professor, Ken Feels, offers them his spacious house, but with an open door policy. Eager for the change, they agree. One evening, as Melody, in a pink skirt, rides Paul's cock, they hear footsteps. Ken walks in, catching the action. Instead of leaving, he joins, making it a MMF threesome. Melody's tight pussy takes both men, her moans echoing through the house as they fuck her in every position, the open door policy adding a thrilling taboo element.
