Bored with their friends, Keitaro and Natsumi retreat to the beach for a private game of their own. Natsumi, a self-proclaimed 'big-dick enthusiast,' can't keep his eyes off Keitaro's impressive package. They start with tentative strokes, their eyes locked on each other's bodies. The game escalates quickly, their hands flying as they push each other closer to the brink. The beach becomes their playground, their moans and grunts echoing as they bring each other to explosive, body-shaking orgasms.
