Mean Guessing Game With Railing Crops

I want to play another mean game with the slave. I brought along 3 different railing crops - a crimson one, a beige one and a black one - and after blindfolding the slave, Ill hit him with the crops and hell have to guess with which one :-D And if he guesses wrong - Ill proceed to hit him until hes right :-D Of course his entire back side gets hit again and again - from his shoulders to his butt cheeks! After a while his entire back and butt are covered in painful crimson marks and you can tell its getting firmer to take for him with every hit. And of course, were going to play this game as long as I want to play it - thats the only thing that matters!
