Its often true among our models that physical exertion leads to sexual tension. In this case a run around the park leaves Benoit and Ben extremely horny with Ben getting an instant- and understandable- hard-on the moment he hops in the shower with Benoit. Benoit notices this and takes command relieving his friends sexual frustration with some hungry ass-eating followed by energetic fucking. Benoit satisfies his own needs by shooting his load all over Bens waiting ass and then, using his own cum as lube, slides in and out of Ben. I dont think either boy will have trouble keeping up with their fitness regimen if this is what it leads to.
