When you pull out of a girl, as you are about to cum, and then discharge your jizz from your wand into her belly button creating a mystical pool of memory and experience, similar to that of Dumbledore's Pensieve.
I don't like to cum inside girls, i like to execute the pensieve.

The other day i was having a wank and i came so hard i pensieved myself.
