Certain slaves never get the picture and need extreme punishment in order to get the point of submitting to a powerful and sexy mistress. This is the case with this sloppy slave. Rules must never be broken, therefore a punishment of getting trampled under a pair of hot sneakers is going to be the punishment, so this slave never messes up again. He will learn the hard way.
Some slaves just do not obey the rules and need to be taught a lesson with pain. The ultimate in pain is the cock crush. Princess Pumagirly is going to make sure when she gives orders they are obeyed from now on without any problems. A cock crush should do just the trick and the slave will always obey from now on. Ouch, it might hurt a bit.
