I recently started playing with some new kinks in isolation, one of them is the interesting practice of Urethral sounding. I got a little kit and you get to see me play with my ones between 3 and 8mm, I know I can take the 3 mm and 4mm so I start with that moving up until my hole can't take more (at the 7mm) going back down I finish myself off I hope you all enjoy this and to play responsibly
