Kurumi Rei-chan, who is popular among the otokonoko fans for her irresistible M reactions. In this work, she fully demonstrates her masochistic nature, a total of three obedient and submissive episodes plus extras! When forced by a classmate, sexually harassed by a superior, or as an M pet that absolutely obeys her master, her M body reacts strongly to men and her penis becomes fully erect! Even if her anus is forcibly penetrated, she moans sweetly, and with intense thrusting, she reaches anal climax and ejaculates explosively from her penis!
