At the request of a man who wants to be cuckolded, his wife is invited to film a ``private AV'' that records the couple's sex. She starts filming, but her husband doesn't get an erection... So she introduces another man to the couple as a substitute for her husband. Her wife accepts to act as a substitute for her husband who doesn't have an erection, but on the condition that he ``no deep kisses,'' ``no blowjobs,'' and ``pretend to have sex.''
