Shiofuki Ama (1979)

Shiofuki Ama (1979) stars Akio Kaneda plus the mucho-cute-o Yuko Asuka as a girl who often loses her top. She doffs it (and everything else) in bed while getting a good banging; she bares ass-uka and bazongas while skinny-dipping in the ocean; she skips back into bed to bare more bits while doing the horizontal twist; and then she rolls around in the sand with her succulent tuna rolls on display! Forget the land of the rising sun, Japan is the land of the rising sperm gun, and you're invited!
