fuck this is incredibly hot ive realised too. Muscular fit guys are sexy and having them submit to a less fit guy with a bigger cock is hot. Its like the only reason they workout is to make themselves pretty and presentable for some top, even though you would think the muscular guy would be the top.
But these men are probably overcompensating for their smaller dicks, insecurities or whatever. So while they workout, they are actually doing it for some "true" alpha to be able to feel up their curves and grope their muscles, they are the sissies in the end. The top doesnt feel the need to be in best shape since the bottom will be crawling to their fat cocks. And to top it all of, the bottoms usually have fattest and tightest asses from the exercise they do, and the muscles helps ensure they can hard a hard pounding hand have high stamina. I wish there were more of these type of thick bodybuilders out there.
