Squeezing orange juice
When you twist your penis so damn hard that you start peeing, an actual method is used in the toilet for a lot of sexual pissing. Used as a very pleasurable way to piss in the toilet. It also happens when someone gives you the vaccum seal double hand twist gawk gawk combo 3000.
