The girls who look great in school swimsuits are members of the swimming club who came to Okinawa for a training camp. They endure the strict instruction of the coach as they aim for the national tournament. In the swimsuits that fit their bodies perfectly, they are given passionate instruction on erotic stretching, leg jobs, swimsuit jobs, and cardiac massage. Before they know it, their private parts are getting wet... The girls who were taking a break are also teased by the owner of the guesthouse.
