生徒想いの教師・麗はブラをつけ忘れたり、無自覚でおっぱいを押し付けてしまったりするちょっと天然な学園のマドンナ。多感な時期に差し掛かった生徒の優太はそんな麗のせいで、勉強に集中できず成績が下がり続けてしまっていた。その姿を見て心配した麗は、ある日補習にやってきた優太に対してH な提案をするのだった…。
Rei, a teacher who cares about her students, is a slightly natural school Madonna who forgets to wear a bra and unconsciously presses her breasts against her. Yuta, a student who is approaching her sensitive period, can’t concentrate on her studies because of Rei, and her grades keep dropping. Rei, who was worried about her appearance, made her haughty proposal to Yuta, who came to her remedial lesson one day.
