In the echoing emptiness of the gym, Eric and Brody's grunts and groans intensify. Eric's cock slams into Brody's tight ass, his balls slapping against his stepbrother's skin. Brody jerks himself, his abs clenching, as Eric's fingers dig into his hips. The air is thick with the scent of sweat and sex. Eric pulls out, his cock coated in lube and pre-cum. Brody turns around, taking Eric's dick into his mouth, cleaning it off before Eric stuffs it back into his ass, fucking him against the gym wall, leaving handprints and sweat stains behind.
