In an adult school role-play, a shy student falls instantly for Mei Washio, the baby-faced, big-breasted nurse admired by everyone. After a fake illness fails, he deliberately hurts his arm just to see her again and nervously confesses that her breasts make his heart race. She privately reveals her bra-covered tits, lets him touch them, and gives him a titjob so he can return to class. Six months later, on graduation day, he finally gathers the courage to ask the woman he cannot forget to take his virginity.
