Cheating On My GF With My Sister's Hot Friend, 17 min

My sister's hot friend decided to sneak into my room one night when she was staying over. She decided to take a peak and sneak into my room. I always knew she wanted me by the way she looked at and flirted with me. I thought maybe she was just going to come in and talk to me. However, she laid down with me, rubbed her huge ass against my cock, until I was so horny I had to slide it in.
