So you can do what with them?
Just this or other things?

There are a numer of resoucres on the Internet that may be of help depending on what you are trying to acheive.

A basic CBT - "cock and ball torture" guide can be found here:

Extreme restraints has a nice article on cock rings:

There's even a book called "Ways to Play with the Family Jewels" by Hardy Haberman

Balls don't really swell when tied. You may be thinking of infusion. That's when sterile saline is injected into the scrotum and it inflates like a balloon- you can really distort the poor subby. (Try a Google search of image search for 'scrotal inflation'.) I've never experienced it, but it's supposed to be quite intense for the subject, and it can't be deflated with a needle. The saline gets into the tissue and must flush out naturally. It can take a couple of days.

jmanque is correct. Balls don't swell when tied. They may appear to swell, as tying them off tends to stretch the skin. They'll also turn red then purple due to restricted blood flow.

Scrotal infusion doesn't cause balls to swell, either. Just the ball sac will get larger and that is through inflation created by the saline injection.

What does cause balls to swell is injury. A good way to cause that is percussion play. Tie the balls so that they'll stay in one place or hold them in a loop created by your thumb and forefinger. Take a light wooden or leather slapper, something the size and heft of a paint stirrer and start tapping them, increasing the swing over time and listening for a fairly constant "keening" sound from your bottom (sub or slave). Take things slowly and in a while you will be administering some pretty sharp whacks to the balls. You can move from your paint-stirrer to heavier thud with care. Your bottom won't particularly like this kind of play and I recommend a certain amount of restraint to keep him from walking off.

Do this twice daily for a week and you will get measurable swelling. I speak here from actual experience, having measured mine before and after one and two weeks of this kind of regularly-administered treatment.

Careful topping in this way will result in consistent sensitivity without serious injury. This did not lower my sperm count appreciably.
