陽ギャルだけど性知識ゼロでエロにウブな幼馴染（ほぼ処女）と、セックスの練習をすることになっちゃった僕。青空ひかり

Overview

Hikari is a gal who has been having trouble with her dates, namely, despite her looks she doesn’t have a lot of experience and she feels nervous about sex. She watched a few porn movies, but she still feels clueless. So she approaches her old friend Yudzuru, a goofy but trustable guy who is practically a virgin, for her to practice up.
