From Centurion Muscle Vol. 10 - ... Danny Mann and Colin West Runtime:

Danny Mann, a fully-bearded muscle bear, can be as tender as he is gruff. Crouching between his thighs is Colin West. At first all we see of Colin are the wild and expansive tribal tats which cascade over his back and triceps. He's busying himself with Danny's cock, clothed only in a jockstrap, shockingly white in the dark space. His muscular build makes him as powerful as Danny, but for the moment, he's content to be subservient, puffing up his chest and hoping to impress his fuckmate. Danny responds by bunching up his fists and pounding Colin's chest back down, forcing him to focus on sucking his prick. As Danny gets blown, he peels off one layer of clothing at a time, slowly revealing a furry chest and raging tattoos of his own. The lighting here throws gorgeous shadows over their bodies, creating deep canyons underneath their pecs and making already impressive muscle look that much bigger. When Danny catches sight of Colin's ass, he gives the twin muscle the same pummeling with his knuckles, an erotic prelude to the fuck that's about to come. Having a humpy lumberjack between your legs would inspire most men I know to grab their pricks and jack. Colin patiently holds his ankles and concentrates. Unable to resist, he does eventually flog his prick until it erupts, his silver Prince Albert jangling while the cum flies. Daddy Danny gets off just moments later.
