This week's GFR submission is all about ass. Our submitter can't wait to get his hands on it so he starts filming this video all the way from the subway. However, when they get back to their apartment, things get hardcore as that ass gets pounded until you would swear it goes flat. But nothing could flatten those ass cheeks. Watch closely and you'll feel like you're sitting in the front seat of a Cadillac when the air bags suddenly explode.
