Slave Wife

My wife is very very submissive. She is my slave most of the time, yet in all appearances she is the nice little wifey. She is very svelte, good looking, tight bodied, and sub ! Last weekend I rented a slave from her master for the weekend. She did all the cleaning and I made her lick my wifes pussy to orgasm. Neither of them is lesbian or bi, but they do as they are told. Each time I fucked the rental I made my wife insert my cock into her pussy or ass and then go stand in the corner while I fucked and shot off in the slave.
