A married woman films herself having sex with another man at her husband's command, who has a desire to be cuckolded. This is a documentary of a married woman recording herself having sex with men other than her husband. Married woman Eriko, 26 years old, in her second year of marriage, no children. Even when she comes to the hotel with a man, she seems calm. She receives caresses expressionlessly, but her breath quickens when her crotch is stimulated. She narrates while moaning, 'It's being licked down there,' and immediately adds, 'But you are the best.' She lies about not having orgasmed as he thrusts his penis quickly, but screams in continuous orgasm when her depths are stimulated and apologizes to her husband. Later, she is blindfolded and restrained with toys, arching her hips to reach climax. Again, she is penetrated by a penis, screaming and orgasming repeatedly. Her thoughts afterward are 'My mind went blank.'
