Thats my job too. I'm not allowed to go above her navel. My zone is her pussy,asshole and her feet. Sometimes he cums on her feet and I must lick it off. I'm not allowed to go near or touch her brests. She says those are for real men. She also loves to use her whip on me.Yes I understand my role now once my wife discovered that there are guys with better and bigger cocks then mine and they understand how to please her my submissive side came into play, I now am happy just cleaning her up and licking her pussy and asshole
