I get to dance with my friend's stunning girlfriend, but I can't resist rubbing my ass in front of her boyfriend, leading to an intense encounter

I'm a lucky guy, I get to dance with my friend's stunning girlfriend every time she's around. Her curves are to die for, especially that big, juicy ass. I can't help myself, I just have to rub it right in front of her boyfriend. He's cool about it, I guess he knows I'm not into her. But the way she reacts to my touch, it's like she's begging for more. And when we're alone, I can't resist taking her from him. We're both amateurs, but we know how to fuck. She's Latina, with a body made for pleasure. I take her from behind, her big ass bouncing with every thrust. It's a sight to behold, and it's all thanks to my friend. I'm sure he wouldn't mind watching me fuck his girl again.
