I want to become Karina-oneesama's partner... Ruru, a junior student, steps into the 'Punishment Club' in hopes of being recognized by Karina-oneesama, who is the object of admiration among the students... Slaps, clothes pins, full-body bondage, toy training, shameful lessons, bitch training, penibann iruma, urine disposal... Ruru's body awakens to pleasure as it undergoes the harsh punishments given by Oneesama... Arisu Ruru has awakened to true bondage SM lesbianism!
