The lively female student Konatsu finally enjoys her long-awaited school trip with her classmates, but she accidentally breaks an expensive-looking vase at the inn where they are staying. The terrifying female teacher Tsubasa punishes her by ordering her to sleep alone in a separate room. Late at night, a hand sneaks into Konatsu's futon and starts groping her breasts. When Konatsu wakes up, she sees Tsubasa-sensei, who was angry with her earlier, playing with her own nipples. Paralyzed by fear and pleasure, Konatsu can't even scream as her breasts and pussy are licked, and she ends up climaxing. The next day, Konatsu, who is self-conscious about her large breasts, goes to the hot spring alone, but Tsubasa-sensei appears there...
