Ogawa Momoka, a teacher of Shimakuri, teaches the students of Shimakuri Academy the lessons she has learned from her own experience, with practical examples! This time, she teaches them about infinite edging ejaculation control! The person receiving the instruction is Koi Kurumi, who has a cute smile, a petite body, and huge breasts! They hit it off, saying that they love the smell behind the balls! They also have erotic discussions full of dirty talk. She showed us how to control ejaculation to the brink of the limit with a sticky blowjob and handjob, and an onahole! She gives a titjob with her huge breasts, licks the nipples, and stimulates the man to the point of orgasm with an onahole! She continues with a face-sitting and an overly erotic lesson, making the man lie down and press her face, and then she fucks him with a face-sitting and cowgirl position! The effect of ejaculation control is amazing! Two consecutive creampies for two busty, plump actresses! Momoka-sensei uses a super sadistic M actor, and her teaching and sex methods are erotic and lively, so to put it mildly, it's the best! Kurumi-chan is also perfect for the role of an honest, sexy, cute busty student! There are plenty of things to see, things to point out, and things to jerk off to! Don't miss it!
