A thrilling story depicting a married woman's shame and sense of guilt, torn by inner conflict. Responding to her husband's cuckolding fantasy, Rina, a 34-year-old housewife married for five years, initially resists kissing. But as her sensitive spots are teased, her breathing grows heavy, becoming so aroused that she leaves wet marks on her underwear. Stimulated by fingers penetrating her vagina, she squirts forcefully even while sitting on the tatami floor. Penetrated by the man's cock, her face flushes red as she reaches climax. Minutes later, in the bathroom right after a bath, she takes doggystyle from behind, writhing in ecstasy in front of the mirror, climaxing repeatedly. Continuously thrust into deep, she experiences successive orgasms, sweating profusely across her face, losing all composure as she's ravaged again and again.
