GENU-007 A retired wife and her salesman husband swap partners with his divorced boss and younger wife

Miho is a full-time housewife after retiring, while her husband Kentaro is top of sales, but their sex life has gone flat and they barely talk. Kentaro's divorced boss Tooru remarries Mao, two years younger, and invites the couple over after Kentaro hears him boast about his wife. That night, both couples have sex with each other's partners, and the excitement leads to a four-person creampie orgy. The 125-minute release follows this first-time partner exchange.
