Several years ago I met a guy with the biggest balls I'd ever seen. And that's all I did do, see them. They seemed easily twice the size of any other big balls I'd seen. I had no way to ask the guy if they were natural or pumped, but I've always wondered. A few times I've seen guys on the Web showing their pumped balls and thought they looked a bit un-natural. I guess I like the goose-egg sized balls but not the really, really huge ones. OK, so I'm wondering what ball pumping is like. Does the process take a long time and many sessions? Is there any danger of harming your good friends down there? ;-) How long do they stay pumped up before they go back down? How do they feel (both when they're your own and when they're hanging on someone else)? Do they seem to be heavier and hang lower? Does the process have any effect on cum production? Obviously there are guys who are VERY in to this. I'd like to hear from them.
