Quite readily!

Your latex dressed sub clamps his lips down around your cock and then starts to bobo up and down it length. His tongue swirls around the tip and underside of your cock as he gets more and more into it. One of his hands gently jerks the shaft he can´t fit into his mouth while the other snakes down to his crotch and starts jerking him off.

You reach down and stroke his latex covered head, gently pressing it closer to your crotch. He´s getting better and better by the minute. you might blow in just a few minutes at this pace. But do you want to cum in his mouth? Or would you rather cum up his tight ass instead?
