A serious honor student wants to be the teacher's only female.

"I like you, Sensei. Please go out with me."
Takako Fujii, a member of the kendo club, is a beauty and a brain that's beyond my reach. The girls rave about her tall stature and coolness, but as her coach, I see her as a cute student. One day, Fujii calls me in and confesses her feelings! We can't date as teacher and student... To make Fujii give up without hurting her feelings, I decide to disillusion her by showing her explicit adult videos! I'm relieved that she's given up as she runs off, but the next day she calls me in again. (I wonder if she'll sue me for sexual harassment...) However, when I'm called in, Fujii is waiting for me in an empty classroom, and she starts taking off her uniform right in front of me...?!
"I'll try my best to become the kind of woman you like, Sensei."
There, I see Fujii, clad in slutty underwear just like the actress in the adult video I showed her yesterday! Unable to resist the sight of the earnest Fujii desperately serving me, I end up raping her violently, but she doesn't give up and continues to seduce me, becoming more and more erotic as I let myself be swept away by Fujii's devoted feelings and slutty body and have sex with her!
