I have had some big ones... I think my record was around 14 full spurts, which felt incredible. I sadly didnt get that one on camera...
Here is one that is 11 spurts and a bit of dribble:

And another, was ridiculously horny and hard and did 13 big spurts, I think half of it went over my shoulder:

Most of my other videos are fairly large like those too, but I think they are the bigger ones... if you dont like having to click back and forth there are 2 compilations that ive made, full of lots of cumshots like these
