Working at a blood donation center in Tokyo, nurse Taira Arasawa is gentle and soft-spoken. Even behind her mask, her pure and refined aura is unmistakable. The crew sends in a male actor to approach her under the guise of a casual pickup. Taking advantage of her kind nature, he gradually seduces her until they end up having sex. Taira has an extremely sensitive body—so sensitive it's become a personal complex. She's only had three partners in her life. Seeking to break out of her shell, she gives in to the smooth progression of events. Her reactions are intense: she can orgasm just from ear stimulation, her nipples tremble involuntarily, and without any deliberate stimulation, she climaxes repeatedly. Despite having only three prior experiences, she squirts powerfully in all three sex scenes.
