Every couple of years we do a deep impact udder torture video - I don't hold back on the strikes. This time I did not bind her udders tight (see 06-Nov-2014 Extreme Tit Torture video for tightly bound udders). I wanted to watch them bounce around. Unlike many other video we do, the deep impact video are of a session that will cause very deep bruising and last for well over a week. The slut slave (@curiousfern) reports her udders turned yellow after a few days like they were covered in mustard. In the past when they were tightly bound they turned purple.
