I have to say that the 3 times I went to him it was over after 30/40 minutes. But that's because each time I came too soon...
He is not the "let's cuddle after sex" kind of guy (neither am I honestly, especially in a situation with a fucking buddy, paying or not), but in no way I felt he was pushing me to leave. He always even offers me to shower.
That half hour has always been very intense and passionate. He kisses, sucks and pays attention to the things I like done. He likes to be in charge and dominate the session. He has the tendency to wanting to fuck you, but I always tells him to wait for more making out. The problem is that the way he fucks, I have not been able to hold on.....
And, by the way, he is more than 30% cheaper of the regular fees you mention
