Something about seeing a guy in white underwear, all wet and cock-clingy. I rather like the guy soaping up in the shower. Wouldn't mind joining in there, make that dick nice and hard and make him cum through his wet undies, suck it dry cum and water.... okay, getting carried away there. Have my own little wet spot now.
Don't know if it's really so true what they say about most black guys, maybe I've been just unlucky with the ones I've seen, but judging from the size of these bulges it looks like the black guys might just have a case!
