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. I start filming, but my husband doesn't get an erection... So she introduces another man to her husband's place. A wife accepts to act as a substitute for her husband who does not have an erection, on the conditions that ``no deep kisses,'' ``no blowjobs,'' and ``pretend to have sex.''
