A beautiful older sister working at a mahjong parlor is a Dommist slut. During interviews, she talks enthusiastically about current mahjong parlors and gaming situations. Since it's M, she teases by giving her light slaps or neck strangulation, but it seems not enough as she begs for more intense treatment. As her masochistic fervor increases gradually, she experiences multiple orgasms while violently shaking her hips. After being restrained and teased, she receives an oil massage to relax her body before engaging in another round of passionate sex that leaves her completely disheveled.
