Fontaine à sperme en caressant une bite nue et non circoncise

I asked my online dom what it's like to wank without a foreskin, his reply was "good idea, you're about to find out" I was told to use a small glans ring to help hold my foreskin back and he suggested lube which wasn't something I'd thought of. The head was so incredibly sensitive that it's hard to tell if it was pain or pleasure. It was like nothing I've experienced before
