CMV-181 Tight-fitting crevice training with rope-walking discipline; a perverse woman, Nao Nanami, who gets off on rough mating and slapping

A model confesses to having a submissive side without realizing it. Unsatisfied with ordinary intimacy, she seeks more serious restraint training. Wanting to experience the embarrassment, discomfort, and pleasure of being bound, she is tied in a hogtie and subjected to rope restraint. Overwhelmed by the intense pressure, she writhes in reaction. As her sensitivity awakens, she is further bound and stimulated. With repeated rubbing, she becomes visibly aroused and reaches a peak of pleasure. Tightly tied, with her nipples stimulated and her mouth held open, she dribbles in humiliation. Through mechanical stimulation and slaps, she struggles in a mix of pleasure and discomfort before climaxing.
