Do you think he's a pro sucker? or the guy's just really intense?

I had a guy go down on me one time and while I didn't cum, I can fully relate to the way that guy was feeling. I left the guy's place all tingly and shaking.

so do you think there's something inside his throat or mouth that creates that tingly and shaky feeling? or is it just really the way he sucks?
 
He gets the guy off, but he's not that imaginative at sucking cock. No real tongue play, for example.
 
There were a few other videos of these two together, maybe 3 total.
Yeah, another one is like this one, he sucked him off, while the other one is him sitting on chadluv's face while he jerks off and cums I think, but that stud is just so hot, he's one of those who doesn't need muscles to look hot, I wish there's more videos of him somewhere
