A private couple documentary showing the everyday intimacy and sex these adult women reveal only to their boyfriends. Akari, 22, is an adult beauty-school student and obedient masochist with mature allure and a teasing dominant streak, eventually overcome by pleasure. Fumi, 22, is an adult nursing student with a gentle Japanese look; seemingly obedient but selfish and sexually voracious in bed. Miya, 21, is an adult student and bar worker from Kyoto with G-cup breasts, a thick curvy body, and few sexual inhibitions. Yurie, 32, is a counselor who unleashes urination and squirting while revealing an innocent side only to her boyfriend. Their uncensored private behavior, fetishes, cosplay, oral sex, facials, and wildly intimate homemade sex are exposed on camera.
