Couples' Ride (Four of Us Ended Up in the Same Bed)

Chen Yu discovers that his wife Shen Yun keeps saying she's 'tired from riding,' yet she's tangled up naked with her cycling coach Zhou Tuo at the studio. Lin Man finds Chen Yu and says, 'You were standing outside the crack in the door, your hands were shaking.' She takes him to the riverbank to take revenge with her body. Two tents, two couples—four people rode all the way to the same bed. The coach rode off with my wife, and I rode off with his. But once they reached the bed, no one could say anymore who was riding whom.
