My friend's girlfriend's amazing butt led to an unforgettable threesome

A close friend of mine has a smoking hot girlfriend with an incredible ass. When we were hanging out, he showed me a picture of her tight, round butt and I was instantly hooked. I knew I had to have her. So, when he went to the bathroom, I slipped into her room and started exploring her body. She was game and we had a wild time. When my friend came back, he joined in and we turned it into a steamy threesome. It was a dream come true, with both of us taking turns pounding her from behind. She took it like a champ, moaning and screaming as we drilled her tight pussy. The sight of her big ass bouncing and her moans of pleasure made it an unforgettable experience. We left her completely satisfied, with her cheeks covered in our cum. It was a perfect night, and I can't wait for another round.
