Anal sex with a large bodybuilder where he preferrably bottoms.
I had the sweetest muscle sex with Mr. Olympia just now. His 20-inch arms pushed me deeper into his hole to stroke his sphincter and pleasure his prostate. His glutes throbbed against my cock as he came after I fucked his muscle ass right nice!
