When your girlfriend isn't ready for anal sex yet, so you put it inside her pussy and you both pretend its in her ass. Usually best with some kind of verbal roll play.
She says "Lets have pretend anal! Oh baby, put it in my ass! I need it deep in my ass!" Then the guy bends her over and puts it in her pussy and says "Oh baby, your ass feels so tight around my cock, I'm buried in you so deep" and continues to fuck her pussy while they both make believe its in her ass.
