I'm a 29 year
old Dutch guy.
I'm living near Eindhoven (South of Holland).
I'm straight, maybe unusual for a pumper, but that's the way it is.
(I like girls too much, but like to see other guys pumping their nuts.)
4 years ago I surfed on the Internet and visited monsternuts.com
I got interested immediately! Since then, I pump my balls sometimes.
It gives a great feeling having that sized balls!
This is my biggest
pump since I developed petechia problems last summer.
I've learned just how far to go without popping a red spot on the
glans.
Man it felt great pumping up those eggs!
I love it when my cock gets superhard in the jar.
Pumping the nips at the same time sure added to the pleasure.
By the end of this session I was so horny I had to do a tube jerk.
Took a cumvid which I will post to the site one of these days.
