A young man named Shindo can't take flights very well - he gets motion sickness and begins to feel nauseous. This time, he is in an awkward situation on an airplane. However, he is soon given medicine and the young man is released. A little while later, the plane gets caught in a storm and begins to shake terribly. The plane suffers severe engine damage and they crash into the sea. A young man with a group of girls ends up on a deserted island. Any man's dream comes true - to be in a tropical paradise with several beauties. The girls gradually begin to adapt their clothes to the island's climate, which clearly pleases the protagonist, but he is terribly shy of it. When the girls go swimming naked, the cunning guy starts peeping on them, but a girl named Asami catches him red-handed. She doesn't say anything to the others, but literally pounces on the guy. As he finds out seconds later, even the girls can't hold out for long and start making love to each other. Meanwhile, one of the girls is fondling herself in the woods. She reassures herself that it's physiology and she needs satisfaction. Toward evening, three girls surround the naked Naoki and begin to fondle him. He resisted at first, thinking they didn't like it, but he was reassured that the girls also masturbate, but sex is much better to try. Suddenly, their teacher finds them. At first she is shocked by what she sees, but then she joins the guys...
