Texas Sex Slave

I live in a guest house owned by some rich people. I was hired to clean the pool, hot tub and I guess you could say their own sex slave. I now consider myself as bisexual because of what I have learned to enjoy. She has this thing about having her asshole licked while he is fucking her. She gets on top and while they're fucking I lay between his legs and lick her asshole. Sometimes he pulls out and I have to lick his cock clean and lick her pussy a couple of times before I guide it back in for him. After he cums I have to lick her clean and he usually sucks my cock. She has this thing about her ass. Sometimes in the middle of the day she makes me rim her till she cums. The money's good and the rent is free and I have some good times, what more could I ask for.
