Is it possible for men and women to form a friendship!? The target was college students spotted on the street! Two men and women who answered "It can be formed" participated in a game to test their friendship. The rules are simple! Just spend the night on the bed in a love hotel! If they do nothing, they get 50,000 yen! If they have sex, they get 500,000 yen! Plus, an additional 100,000 yen for each extra act! However, there is only one condom. In a secluded room, the sexually aroused college students, alone together. Seniors and juniors. Classmates. Even those with boyfriends or girlfriends... In the end, everyone was having unprotected sex non-stop!
