Kanako,who works in the design development room,doesn't seem to be interested in good-looking guys. She only cares about swimsuits. One day,she is reunited with her childhood friend,Fukase,a swimmer who represents Japan,as he comes to her office to make a new swimsuit. Kanako,who is in charge of Fukase's size measurements,is fascinated by his grown-up,manly body. "It's not fair if I'm the only one who's stripping,right?" Fukase says as he takes off her clothes! He begins to explore her sensitive body all over,turning her into a dripping mess and making it impossible for her to resist...!
