Tuyoshi, with the memories of an adult, time-traveled back to his student days. There, girls like Yui, who would eventually become a national idol actress, along with other cute girls, innocently and unguardedly exposed their bare pubic areas, just-sprouting pubic hair, or budding breasts during the pre-swimming class changing time! The heyday of mischief, indecency, and lewdness with innocent girls who know nothing about sex begins!
