Amateur newcomer Yui travels two hours from a quiet seaside town to make her first porn appearance in Tokyo. Behind the modest glasses are natural H-cup breasts, poor eyesight, a passion for writing erotic fan fiction, and an unexpected background in aikido. Though still a virgin, she has worked at a handjob parlor to gather material for her stories. Her mysterious mix of innocence, embarrassment, and raw curiosity is on full display.
