A Glorious Discovery
Well since Rod has worked up quite a boner during his gym routine, he's gonna see what happens when he sticks his big cock through the hole. And when it pops into James's bathroom stroke chamber, James has no problem rubbing his own hard man pole together with it. Rod decides to suck this mystery dick to see what it tastes like. This gets James all worked up and the two finally show themselves. James figures he might as well fuck Rod's ass while they're both in the bathroom, naked and erect. Hey, it's just common gym courtesy.
