Yuma Miku, debut bondage work! A pure body that has been bound and tightened to the limit! Continuous training turns Miku into an even greater masochist. Three months after transferring, although I've settled in with my classmates, every day is frustrating... Am I precocious or a pervert? My classmates can't understand my fetish... Days of masturbating while self-bondaging after reading SM erotic manga. One day, Miku sees her homeroom teacher entering an SM club. 'So the teacher is interested in SM...' Miku asks the teacher, 'Please train me.'
