-Custom- Yet another pulverizing Boston Crab request! I have my slave tied up, blindfolded and gagged with socks. This one contains 10 minutes of hard crabbing, 5 minutes full weight kneeling on his back, then painfully pressing my knee onto his neck for another 5 minutes, finishing off with a minute of facesitting at the end. All throughout I deliver evil and humiliating talk, dominating the poor wimp physically and mentally. Enjoy.
