Remember in PE when they'd make you stand, back to the wall, knees bent at a 90-degree angle? Yeah, we sucked at that. One look at the haunches on this dude and we can tell that he was really good.
It's not just this muscle top's gorgeous thigh-buttock area that gives us this idea either. What really impresses us is that he manages to fuck a bottom who's on his knees from a standing position for, you know, a pretty considerable amount of time. Many a time have we been forced to half crouch/half stand while fucking someone considerably shorter than us. It's definitely not as easy as it looks.
