Dude-Only Academy -A Teacher Trapped with Sadistic Beasts-

"You're a virgin, aren't you?" I've been found out, and now the students of this all-boys academy are looking at me like I'm their next meal! Sayoka Tateno works at a school full of boys in the countryside. Wanting to work in peace and not stand out, she wears a tracksuit and avoids showing her feminine side. But one day, she finds a mysterious piece of paper in the hallway that has a strange effect on her body. From that day on and against her will, she can only wear sexy, revealing clothes! Not only that, the students somehow found out that she's a virgin!
