NGR - Nagasare - A wife who was raped by her brother-in-law and found out she had her first orgasm

Although she is serious, Ai secretly feels unsatisfied with her husband, who has a special fetish. At that moment, her brother-in-law, Bunta, suddenly visits her house. The playboy brother-in-law spots her helpless spirit and skillfully seduces her... He is swept away by his mouth, and Ai ends up having a relationship with him saying, "once once." After that, she continues to refuse Bunta, who has been persistently tempted, but the pleasure that her husband can never experience, which stimulation that sways her whole body, and the stimulation that delves into the vagina walls are violently engraved on Ai's body.
