I finally got my first girlfriend, but I'm still a virgin and I don't know how to date a girl! At times like this, I turn to my childhood friend, Akari, who has been with me since we were little, for advice! She makes a surprising suggestion: "Why don't you lose your virginity to me for now?" I don't want my girlfriend to know that I'm a virgin, and I don't know how to do it, so I decide to practice sex with Akari! I finally realized something while having sex with Akari, who teaches me how to give a blowjob, cunnilingus, and even creampie.
