An incident occurred on the day my friend said he wanted to see the AV in my brother's room and came to visit with me.

One day my friend said he wanted to see the AV in my brother's room, and even my childhood friend, Rin, followed me, and the four of us, went to see the AV together. My best friend started saying, "Hey, let's give it a try too!" They stop them, but the girls seem to be unfair...? The AV viewing party that started out as a prank is a bit of a joke, but perhaps out of curiosity, the four of them end up in an orgy! ! My favorite girl has her first experience with her best friend right in front of me! I've graduated from being a virgin with that childhood friend! A youth orgy that begins with excitement! !
