Whats the trick

What’s the trick, to keeping your balls from being sucked into the tube ,when pumping? Please help!

Just try using no lube. Enter the tube hard and bone press the tube before you start pumping. As long as your cock doesn’t pack the tube, you won’t need the lube to help you get out. Just press your finger in at the base of the tube and the pressure is released instantly to let you get out.

Thanks gprent, I start out using a full package pump, for about 15 mins, then I move to the single stage cylinder. This would keep the balls from being drawn in , but its not the routine I like to do all the time. I’ll try your technique.
