JO in piss filled condom
A friend taught me this many years ago. Put on a rubber or metal cock ring. Fill up your bladder. Put on a condom, XL kind work the best. Stretch the condom over your balls and around the cock ring. Make sure you have a good seal or it could leak. Fill the condom with your piss and enjoy the warm feeling of your piss surrounding your cock and balls as you jack off and then shoot your load. It's a great feeling.
