Mr. and Mrs. Yuki and Mr. and Mrs. Hosokawa, who returned from shopping with four friends, enjoyed the honeymoon with each other as soon as they returned home. Meanwhile, both husbands are consulting about the degree of perversion of their wives in a place unknown to the wives. They ordered masturbation to the wives who remained at home, and they were consulting how much they would be indecent in front of men other than their husbands. The husbands were very much looking forward to the reaction of their wives when a strange man appeared in front of them who invited their acquaintances and continued to masturbate.
