Shiraishi Momo comes to a beauty salon to try out the couple's course. However, it turns out that every masseuse is a perverted, unscrupulous one! Her nipples, which have become sensitive from the oil containing an aphrodisiac, are kneaded and tormented, and she climaxes violently while trying to keep quiet so her boyfriend doesn't find out! The trap of the couple room beauty salon is that she is violated with only a partition between them. Having discovered the pleasure of nipple orgasms, Shiraishi is unable to resist the nipple play, and eventually accepts the cheating raw sex! A silent NTR that mixes immorality and tension.
