Right before cumming squeeze the head of the penis as to not allow anything to come out.
That girl last night gave me a dick lynching. It hurt like hell but was totally worth it!
When you are about to cum and you grip right under the head of your penis as to not let anything come out. It's painful yet satisfying.
Oh my God dude, last night she gave me a penis lynching! It hurt like a son of a bitch, but I would totally do it again!
