You stop him...

...and wait for a second. He looks puzzled up at you but patiently waits. Then he finally understands when the first drops of piss dribble into his mouth. Mark eagerly starts drinking your golden fluid, trying to swallow it all. His cum-covered face and body look great, but you want something different. You take your cock out of his mouth and start pissing his cum away. He starts moaning again, a sound that, together with the sight of Marks cum- and piss-soaked body, is slowly getting you hard again. You put your cock into his mouth again, and he eagerly sucks out the last drops of piss. Then, when he is still suckling your cockhead, you push forward and lodge your 8 inch cock in his throat. He doesn't even flinch and starts licking your shaft. You begin fucking his throat, which apparently he can control as perfectly as he does his hot ass. You feel things you have never felt before, the ribbed sides of his throat are massaging your cockhead as it passes through. Before long, you blow your load and coat his insides with a thick layer of cum. You pull back and he sucks the last drops out, as he did before with the piss.
