At a swimming school, two beautiful female instructors, Rin and Rei, are always the center of attention because of their stunning beauty. Miyamoto, a regular student, often dreams darkly about the two girls, and one day he discovers a strange note taped inside his locker. It says: "Remove this note, and they will completely obey you!" Without hesitation, Miyamoto tears the note off, and from then on, he turns Rin and Rei into his obedient "slaves"... Hehe!
