A great video for any BDSM enthusiast who might want a new and interesting way to punish their slave....or just see me get punished. I put hard grains of rice on the wood floor and then put all my weight on my knees and hold out for as long as I can. I truly am in pain, you can tell with my shouts. It is not the most prettiest sounding video but definitely genuine pain. After I have had enough, I stand up and pick the grains of rice out of my knees. You can see how red my knees are and even indention marks!
