Two beautiful mature bodyboarders who work as instructors at a bodyboarding school. Hitomi Katase, who eats up all the students at the school, and Hikari Natsuno, who looks like a slut but has a strong sense of morals. These two contrasting characters somehow end up being best friends. Hitomi Katase, who likes younger guys, seduces the students at the school in a makeshift shower and invites them to a hotel for some crazy fun. Hikari Natsuno, who doesn't currently have a boyfriend, writhes in agony as she has sex with a male actor for the first time in six months. The orgy with the two brings her to the brink of losing consciousness from the intense sex that only athletes can get!! The serious sex of these bodyboarders who love riding both waves and men is full of impact!!
