MOODYZ's fourth How to Sex lesson promises practical training for better ejaculation control with Tsukumo Yoru. It introduces Kegel exercises for age-related weakness and squeeze-based techniques for sensitivity or psychological causes, then puts three adult role-play students through beginner and advanced lessons. Each must endure Yoru's vacuum blowjob for five minutes to earn sex, and if he makes her climax from penetration, he gets to creampie her. Interviews, demonstrations, and serious sex fill this oversized 200-minute class.
