Master x slave. All stories are pretty much similar. Rape, abuse, bondage and toys.
1st story - teacher gets molested inside a crowded train and his student witnesses it. Student then blackmails the teacher into becoming his own sex slave.
2nd story - student A catches the couple from the first story having sex in school. His classmate catches him watching them and in exchange for his silence, he decides to make student A be his sex slave little did he know that student A has been hiding an unrequited love for him from the start. This one was my fave story out of the 3 couples.
3rd story - homosexual teacher rapes his homophobic student. Homophobic student was molested before when he was younger.
