Emma's first....

just thought this issue is worth to share and discuss here with other bros. god knows how many times I have visited Emma..probably can't even count with two hands. Today I went again..everything is as fantastic as usual..and then....I COULDN'T CUM. omg..after twenty minutes of hardcore exercises from both Emma and I..we surrendered. Cock was still hard and there was just no feeling to cum. By the look of Emma's face and the talk we had after sessions..I am sure I am her first customer that didn't cum in the session...haha..do I deserve a trophy? The only reason I could think of is..I have three professional level of exams coming up next week..could this be the stress that cause this? I wonder what other brother will do when you encounter something like this..I mean the stress taht makes you can't cum. btw. Emma is really a professional that deserves every credit. I tip her more than ususal for her efforts, and she told me it is too much. Aw..
