when you are having anal you hit the girls head on a bunch of shit and knock her out. then her butthole gets smaller because of her being unconcious, therefore you get more pleasure. so you are riding her like a bulldozer in a way because you are running into shit.
dude i did the bulldozer on my girlfriend last night and it felt amazing.
