Nao Jinguji is a tutor, but her teaching method is unique; perhaps these innocent little boys who know nothing are actually the extremely lucky young men. Nao uses her own body as motivation for her students to strive; at the school age, just seeing a sexy girl is enough to excite them, but here they witness their tutor not wearing anything, or boldly behaving provocatively to stimulate their minds, helping them find the motivation to work hard.
