A man who has a desire to be cuckold invites his wife to shoot a "private AV" that records the sex of a couple. I started shooting, but my husband didn't get an erection ... Therefore, I will introduce the man who had been arranged in advance to the couple as a substitute for the husband who does not have an erection. My wife is confused by the proposal to replace her husband with a substitute and continue shooting, but accepts it under the conditions of "do not deep kiss", "do not blow" and "pretend to do SEX".
