After a week of abstinence, and with such pressure on his tight balls, I can imagine how intense his orgasm would have been had it not been ruined. I'm sure, though, that it was deliciously unsatisfying and frustrating for him.
I love how you make him cum around 8.50 and then again at 10.50. The way you cup his balls in your hand after the 1st cum and the way you pull onnthe chain is amazing. I also love how he grab you at 10.50 when he is about to cum again. You have some wonderful hand technique especially when you squeeze the tip of his penis between your thumb and index finger. You have lovely hands quite strong and perfect to torture him with handjobs. I would not last two minutes. My cock is too small and way to sensitive for this. I would be a crying begging whimpering mess.
