SERVANTS FOR GIRLS - Karen - Prove Me Your Usefulness!

I'm going on a date with my boyfriend. I want to look perfect in front of him and my old slave monica will help me with this. She tries to please me but still annoys me. She kisses my hands, combs my hair, buries her nose in my ass, cleans my shoes with her tongue but that's not enough.. Well let's see how well she cleans my feet. I can't go on a date with sweaty feet.. I still think she's pathetic and useless..
