I come to my classmate's house to thank him for helping with the lessons. I want to do something special to thank him and ask if he has ever seen a girl naked. I was his first. To be honest, I've never seen a man's dick before. I do a striptease for him and get down on my knees to give him a blowjob. I've never done this before, but my classmate seems to like it. I sit on top of him and ask him to cum inside me. I heard my mother ask my father to do it earlier. It seems we succeeded.
