Can you achieve orgasm if nothing else on you is touched or stimulated in any fashion except your balls?
Never have, but I'm extremely sensitive to pain there. Tea bagging can put me in agony.
Orgasm NO. BUT, done properly it WILL make my boner a LOT harder (HINT!)
No. It's incredibly pleasant and makes me as hard as a rock, but if anything, it will prolong my orgasm. I love having them sucked though. It's a wonderful way to make a blow job last much longer.
I agree....as much as I like my nuts played with and fondled I need more direct stimulation to cum.
It really depends on how long it's been....but normally, no.
I have never climaxed during any kind of ball stimulation ;)
A full orgasm no, but makes me ooze pre-cum in a big way.
