Married women Hina Kusakabe and Rio Ayanami work out during the day but complain that only their husbands ever get to admire their bodies. Then a handsome young adult trainer appears. Wearing skin-tight racing swimsuits that barely contain their big tits, they ask him to train their pussies too. The close friends take turns accepting his hard cock without a condom and share each other's juices, licking one another's nipples as they show off how loudly they moan during penetration. Hina receives an internal finish while Rio watches with envy, and the three end with a passionate triple kiss.
