Hina Kusakabe and Rio Ayanami are married women who work out during the day but complain that only their husbands ever get to see the results. When a handsome young adult trainer appears, they squeeze into revealing racing swimsuits that emphasize their big tits and ask him to train their pussies too. The close friends take turns accepting his hard cock without a condom, sharing their juices as they lick each other's nipples and show off their moaning faces. Hina receives an internal finish while an envious Rio watches, and all three end with a passionate triple kiss.
