If you have a beautiful latex clad Mistress you should keep her happy. If she orders you to lick her body then do so with some enthusiasm. If she then tells you to fuck her pussy with a glass dildo, put some effort in. I was not impressed with my slaves efforts at all. So just as his huge cock was about to spurt in the midst of ecstasy I drop it. Limp and spurting on his belly was what he deserved.
