He's got a PhD in Deepthroating

How does he swallow that, it's very hot

Me too. And I am also professor in DT :-) My BF trainied my very good to take a 26cm cock with no problem.
Looks like this sucker is my twin. I should invite him over to service my BF together with him.

That's a REAL cocksucker there! That's how you do it!
