I don't have links, but Anabolic's Rough Sex 1 and Rough Sex 2 is some of the best shit I've seen. I remember jerking to it like crazy when I was younger. I don't know this for sure, but I was told that the company received so much flak about it that they later pulled it from their inventory. It's definitely the two films that introduced me to rough sex and made me realize that there's never mercy for a fuckin whore.
to sikopanj :magnificent... but this clip illustrates amply why she should have had her hands tied behind her back first. And hold her by the hair, it's harder for her to resist
