Four couples go to a country house in the countryside to spend the weekend. Vado's girlfriend Lenita is still a virgin and is unaware that Vado agreed with his friends Mario and Durva to play a game in which the reward for the winner is her virginity. She runs away from the feuding boys when she finds out and then decides to have her virginity taken by the country house owner instead (55:00). Meanwhile, the four boys exchange the three remaining girlfriends with each other (knowingly and unknowingly).
Mario also fucks the wife of the country house owner (39:00). She always has a nice smile for her when they talk so this encourages him to make an aggressive move on her. At first, she resists his sexual attack but eventually, she gives in and has sex with him on the muddy ground of an orchard.
