Watch on Soap2day. Nurses Ryoko and Shiori, who work at the same hospital, are roommates living together. While Ryoko was quiet and reserved, Shiori was the opposite—a free-spirited womanizer who changed men like socks. Yet the two got along well. One day, fed up with Ryoko's lack of experience with men, Shiori decides to teach her techniques to please a man. As they playfully wrestle, they can't hide the growing lustful feelings welling up inside each other.
