SFbro90

He recently fulfilled a very specific fantasy I had that was incredibly hot. His body is perfect. He mercilessly fucked my throat — barely giving time for me to breathe — just the way I like it. He then rewarded me with a big load in my mouth. What a stud. 10/10.

well.... maybe he was saving it for another client!
It's difficult for an escort to cum if he's not attracted to the client. 
Was he able get it and keep it hard? That's all that matters to me, besides kissing, etc.

Surely you jest. I don't remember anyone ever 'refunding' me a fee. One time during a meet with a porn star-long retired  unfortunately-I was so nervous.  I tipped him. Then tried to tip more, and he wouldn't take it.
It wasn't him so much as I was in danger of missing a flight home and had to work that evening.
 
I'd wanted to meet this guy for a long time. Then I find out he's in LA while I was there. But due to prior commitments, I couldn't meet until the day of my flight. So I was able to meet. But after we met, I had to get back to the hotel, check-out, and get the rental car back, then have the rental car place get me to LAX. I was a nervous wreck. I made it to LAX barely in time. But it was worth it. I later had two overnights with him. 

I find this to be very high on the list of things providers affirmatively and explicitly agree to beforehand, and then do not do, and think that’s just fine. 

His release 

How accommodating could he be if he didn't perform as promised. Unless he tried and just couldn't physically do whatever it is he agreed to beforehand ?
