I finally got a girlfriend! And she's the idol of our school! But as a virgin, I have no idea how to have sex… In times like these, I can only consult my childhood friend Yui, who has done everything with me since we were kids. Then she says, "Why don't you just lose your virginity with me?" What an unexpected proposal! I don't want my girlfriend to know I'm a virgin and I don't know how to do it, so I decided to practice sex with Yui! She teaches me everything from blowjobs to cunnilingus to in-and-out sex. It's only after having sex with her that I realize… me…
