When a man Masterbates with a condom on.
When I want to Jackoff, but I dont want the mess that cums at the end, I do a Solo Rubber Jack.

The art of masturbating while wearing a condom. Only the people with their PHD in Jackology have used this form of masturbation.
Who needs a tube sock or a paper towel when you can solo rubber jack.
