1. There was an older uke and a high school seme. The uke is like a caretaker for the seme, and the seme is always bringing women home. The seme takes girls home and they think he is a university student but he's actually in high school. The uke likes the seme, and he would refuse to masturbate while thinking about the seme. Then he and the seme got into a fight while they were in the car, and the seme told the uke to get out, and the uke collapse, and was taken to the hospital. And the doctor said he fainted because he didn't masturbate for I think one or two months. They are at the hospital and the uke was in the hospital bed and the nurse gave him magazine so he can masturbate. Then the seme walk in and laugh at him for not masturbating and question him. Then the seme said he will help the uke and that's when they did it. The setting of the story was mostly the seme's house and I don't think there were any scene with the school.
