Slut Slave Punishment - Kneeling on Crushed Nutshells, Whipping, Slapping and Throatfucking

The Master derives pleasure from every moment of my agony. That's why I've been kneeling on sharp, crushed walnut shells for a long time, while the Master whips me and fucks me in the mouth and throat. Of course, all this is followed by a series of bitchslaps if he's not satisfied with how I serve him.
