Keiko, who already has a boyfriend. When she takes off her uniform, her slender, graceful body and surprisingly large, swaying breasts catch the eye. Her nipples are highly sensitive, reacting lewdly to even the slightest touch. Though she claims to dislike sex, her gentle voice contrasts with her naturally responsive body, gradually transforming her expression into something increasingly erotic. Experiencing creampie for the first time during her initial blowjob, she eventually receives a generous creampie inside her vagina, vividly capturing the moment this boyfriend-having girl discovers pleasure for the first time.
