Mio Kimijima is a beautiful woman who craves bondage and abuse, a true masochist at heart. When she puts on a collar, her perverted mode turns on, and she performs twisted masturbation like exposing herself to the flame of a candle. Her slender, big-titted, exquisite body gets so aroused when tied up that she even farts involuntarily. In this state, when her pussy receives intense stimulation, she arches like a shrimp and reaches ultimate pleasure. With both arms bound, she feels pleasure even when her throat is violated by deep throating. Whether it's intense spanking or rough choking during sex, Mio feels nothing but ecstasy, embodying the perfect, genuine masochist.
