My girlfriend wearing a Strap on sexually violates me then we both spank one another

A girl uses a giant strapon and is an active partner switching positions, tying up and spanking and whipping her guy. He willingly bows his neck and gets positioned for her to penetrate him as she uses various toys that appeal to her sadist side. Their sexual drive is simplistic and their raw passion leads the movie to an unrefined, unedited and raunchy ending.
