[IKIK-003] I gave my virginity to my sister's friend who suddenly showed up lol But it was all planned by my sister lol (Censored)

My sister's friend, who now looks beautiful with black hair, was a former delinquent and a typical female giant who is so selfish that she thinks the world revolves around her. "Have you ever kissed someone? Do you touch your nipples when you masturbate? You've never touched a boob, have you? I'll do it with anyone lol" she said, grinning and loving to play pranks, teasing me, a virgin. "You're already so hard!" The best experience of losing my virginity! My first sex was a creampie...
