Nice when two guys deeply in love can have their cocks sucked at same time.

Or what's the betting that all four cocks will soon have had three sets of lips in turn around each of them? And why not as it'd be a shame not to have such experience to the max. The trickiest decision may well be as to who gets to fuck who - and who gets the spunk of each. 
In this pic what I especially like is the guy second from left giving us a glimpse of the fold high up between his legs enclosing his shithole. Don'tcha wanna get your own tongue in there?
