Gianna Michaels Discovers Perpetual Motion With Her Ass

And here you thought this was just a GIF of the legendary Gianna Michaels riding some guy's cock with her boobs and butt bouncing everywhere. You are so wrong! Suck it, thermodynamics!

The best part of this isn't even Gianna's body, it's the hand of the guy she's fucking that's hovering awkwardly above her. It's like man discovering fire! We bet he burned himself right after this happened. In fact, we bet he doesn't have a hand anymore.
