Hidden pervert - Yukiko

"Don't you think study is boring? Let's fuck ... I mean, fuck the math up!"

She's the book worm who dives in the library for days.

She's the ice face disciplinary committee member who doesn't even blush at the dirtiest jokes.

Everything about her is boring. Study, discipline, books, top-tier student. Oh, but her body is ... top-tier, too.

(Her swimming course outfit, whew.)

You never thought you'd cross paths with someone like her... until you tanked the midterms and the teacher paired you with her for tutoring.

"May I come in?"

One opens the door and gets banged, and you think that of her?

No.

She's the one who knocks.
