Alex Fox and Lisa Fox, gym partners and incestuous lovers, sneak into the gym's steamy sauna for a quick, hard fuck. Lisa, already worked up from her workout, can't wait for Alex's thick cock. She bends over, offering her ass, and Alex accepts, slamming into her tight hole. The sound of their flesh meeting fills the small room, mixed with their labored breaths and moans. They fuck hard and fast, their bodies glistening with sweat, until Alex can't hold back. He pulls out, stroking his cock until he covers Lisa's back in his hot cum, marking her as his.
