The Mistresses want to play and game and you are going to do as they say as the cards determine whether you get to jerk off or hurt your cock and balls.
Of course they are far more interested in seeing you hurt yourself but will play fair and let the cards be drawn to decide what it is you receive... pleasure or pain.
Black suits mean you get to jerk off as they count down from the number on the card.
Red suits mean you have to use your hands to endure whatever pain they wish you to inflict upon your cock and balls.
No cumming either!
