CMN-203 Shinkai Yua: Elite Anal Slave Training Diary – Pure White Boy Becomes New Half, 140 Minutes, Enema, Dressing as a Girl, Humiliation, Transsexual

A carefree college student named Yua Shinkai lives off his inheritance and is forced by his servant to dress as a girl every day, being called 'Master.' One day, his estranged brother suddenly returns home and discovers his secret. Pressured and tormented by his brother, Yua decides to leave home and responds to an ad he found on an S&M dating board, moving in with a stranger. There, he is trained through intense SM play—including enemas, anal sex, and various humiliations—by a man who likes boys, gradually transforming the pure, innocent young man into a submissive male slave.
