Miho, a married woman who is frustrated by a lack of sex with her husband, invites a man she met on a dating site to her house while her husband is away on a business trip and has an affair to soothe her throbbing crotch. Miho repeats her affairs while her husband is away on a business trip, as she feels a tingling pleasure that she cannot get from her husband. One day, she is supposed to invite a man over to have sex as usual, but the man gives Miho drugs and restrains her with his friends. He makes her cum with a large vibrator, then he chases her with his hungry big cock in a threesome that cums inside her, and Miho gradually cums and screams.
