Sam sees River working out his arms in the gym and sits behind him as he stretches, the perfect spot to view the hunk’s ass. The guys flirt silently across the room, and Sam makes the first move as he drops his shorts and strokes his hard-on, crossing to where River sits. The bottom strokes and sucks Sam, then bends over as the top works his hole with his tongue. Sam pounds the bottom from behind and on a block, then River rides Sam till it’s time to take a facial, and he strokes himself till he orgasms.
