I have to mention this I enjoy watching a man's butt shake and bounce. His butt made me horny, wish I could give him a butt rub with kissing and licking of his cheeks. Then hump his crack and cum between his butt cheeks. I have never done this with a guy before just with women. But I would love to try, I believe I would really enjoy exploding between his buns like a hotdog. Might be the best orgasim of my life
