Again, Katia keeps pushing the envelope in this exquisitely painfully erotic installment. The best part about this video is how physically tangible it is as Katia lights a candle and drips the red wax on her naked torso. You'll wince with every turn of the Wartenberg Wheel. Her exploration is almost hypnotizing and I found myself holding my breath, waiting to see what she would do next and how her little body would take it.
