River and Yana are great personal friends who train together in Gracie jiu jitsu. These women know and use chokes and joint locks that we typically ban as our women just aren't trained to take them and know when to quit before getting injured -so this is rougher than 90% of what we normally produce. And there is no quit in either one as both want to be the woman wearing the tool during sex, but only one can be. Nearly 50 minutes of mayhem -real intense competitive submission wrestling and incredible sex between gorgeous women!
