Shy glasses-wearing Ayu (23) appears to be a quiet, bookish girl at first glance, but she's actually a sporty woman who competed in national high school swimming championships. Living up to the theory that athletes have strong sex drives, rumors say her insatiable appetite for sex leaves her boyfriends exhausted. Her body glistening with oil during sensual massage, she passionately indulges in sex, moaning "more... more..." continuously. Even after repeated creampie orgasms, she remains unsatisfied, begging "I want more..."—a true sex monster driven by endless desire. Her sex scenes overflow with an unquenchable hunger.
