My younger childhood friend still innocently comes to my room to play... One day, when I was treating her like a kid, she said, "I'm amazing when I take off my clothes," and showed me her naked body! She then said, "I've always loved you, big brother," and touched my erect penis, making me horny! My younger childhood friend, who I thought was a kid, came on top of me over and over again with a dirty grinding cowgirl position that put an adult to shame! And it felt so good that I came inside her over and over again!
