Tomoko worried about her son, Masanobu, coming home with injuries. However, whenever she asked him, he wouldn't reveal the cause, leaving Tomoko unable to help him. She felt frustrated by her own helplessness. One day, a classmate named Togawa came to visit. He revealed that he and Masanobu were both being bullied. Seeing Togawa’s distress, Tomoko wanted to help and offered to listen to his troubles. Hesitantly, Togawa explained that the bullying stemmed from the fact that he was still a virgin. Tomoko was surprised, but seeing how deeply troubled he was, she decided to cheer him up by letting him touch her breasts.
