Boish de Takashinchou na Kasshoku Osananajimi to Asemure Icharabu Ecchi Shimakuru Hon

She was tomboyish and rough around the edges. We used to play games together, have silly competitions, and do nothing but the kind of things that made us seem like two boys.

I pretended I wasn't interested in her, but the truth was, I was really into her. Then, by some unexpected turn of events, she found out that I liked her. Just when I thought, “It's over... it's completely over......,” she said—

“Wanna... try having sex... or something?”

So we both liked each other?! You should've told me that sooner! Once you discover sex as a couple, you just can't stop! A passionate ode to youth, drenched in sweat and steeped in sex, with a strong dose of eroticism!
