My childhood friend still comes to my room to play, even now. When she has a fight with her parents, she secretly stays at my place. (Of course, I tell her parents that she's secretly visiting.) One day, while treating her like a child, she showed me her naked body and said, 'You know, I'm amazing when I take off my clothes.' I was embarrassed but mesmerized by her beauty, and I got a full erection. Seeing my fully erect dick, my childhood friend got excited and said, 'I've always liked my older brother.' She touched my erect dick and got aroused. My childhood friend, who I thought was still a child, rode me in a slutty grind position, cumming repeatedly on top of me. I was so turned on that I kept cumming inside her as well!
