Description: Robbie is a sweet, clean canvas for us to paint on -- and we paint with pain here at Knotnice. Our brush is a red-hot candle, and we turn our model into a polka dotted work of cruel art. But all is not lost for Robbie, as we make sure to top that pain with a dose of pleasure, ending her stint in the studio with a pounding by the fucking machine and vibrator on the clit.
