The gym is empty, but the air is thick with testosterone and the scent of sweat. Two partners, their muscles glistening, lock eyes in the mirror. One turns to the other, a silent invitation. They move to the locker room, their movements slow and deliberate. They undress each other, their hands exploring every inch of each other's bodies. One leans against a locker, his legs spread wide, as the other buries his face in his ass, rimming him until he's squirming with pleasure. Then, he slides his thick cock into that tight, eager hole, fucking him slow and deep, their bodies pressed together. They switch, the first partner's cock sliding into the second's ass like it was made to be there. They fuck until they're both covered in cum, their bodies shaking with the force of their release.
