The grunts of exertion turn to moans of pleasure as the men switch roles, the first man now on all fours, his firm ass presented like an offering. The second man spits into his hand, lubing up his massive cock before pushing it slowly into the first man's tight, virgin hole. The first man gasps at the initial intrusion, but soon he's pushing back, wanting more of that thick cock filling him completely. The second man obliges, pounding into him with increasing force, their bodies slapping together in a symphony of carnal desire. They both climax simultaneously, their cries of release echoing through the empty gym.
