START-429 Yotsuba Kominato's 'Challenge' channel R18 edition The long-awaited M-erotic challenge. While enjoying the reaction of the M-man, the sadistic slut awakens and milks the masochistic seeds in this documentary. - Yuzu Shinkawa

Kominato Yotsuba, who has almost no experience as a sadist, challenges herself with masochistic sensuality and lewd play in five scenes. She receives instruction from a current lass, and gradually improves her skills with edging, face sitting, ruined orgasm, restraint, and rose whipping. This work is also a worthwhile introductory documentary for lewd women, with the transformation from confusion to awakening realistically recorded. Includes six masochistic male ejaculations and male squirting.
