That plain-looking girl in my class is actually incredibly promiscuous! - Haruyama Ayaka

There's always at least one girl in the class who's academically brilliant but has an unremarkable, "country bumpkin" style, right? This time, Haruyama Ayaka is just such a girl. I thought she was studying diligently alone in the classroom after school, but then I discovered she was masturbating! So I went up to her and forced her to use her body as hush money, and finally, I had sex with her until I ejaculated inside her—it was incredibly pleasurable!
