bro, I finish watching that guy cuming 6x. Its something that many people wont accomplish ( ever) and other that would only even dream to cum 3 times. It was actually funny, the sound effect that he makes.
Anyways, he looks like he probably was using viagra. I am not saying a 40 yr old guy can't do this but he is also very sensitive

I guess it not a good thing when it come to fucking. I would sweat cumming 5-6 times. Is a good cardio workout though. But he didnt seem to challenge his body and heart doing so. But thats great anyways.
I have never taken viagra or any other pill. So, I don't know if I will be able to cum 10 in a row or have a heart attack. 2 days ago I came 4 times in the same erection... then wetn to the restroom while there I told my gf Want to see something? she reply with a yes and I begin masturbating again (thsi was no more than a minute or so after cumming 4 times.) So I came again. The last time when the penis goes down and you get it up again it rested for a little bit so I shoot well 2-3 times and 1-2 feet long..
