My Wife And My Sister

My wife has never been as into sex as I am. She likes it, she orgasms but she never NEEDS it. She doesn't have the drive to initiate. I thought in a moment of drunken sex we were sharing our first time stories and I told her that my sister, one year older than I, was my first. She let me continue but kept asking me about my sister.

My sis is divorced, no kids, and my wife told me one night while she was on top of me, letting me get satisfied, that she wants my sister to move in with us and that way I can have another to have sex with when I want rather than it always having to be her.

I thought it was a trick, it wasn't. After 20 years with my wife in the bed, i fucked my sister again. Now we all live together and I get as much sex as I want. To my liking, I can get anal from my sister as my wife never did it and never will. My wife has even cleaned my cock after cumming in my sisters pussy. I really think she likes the taste of her and wants her also.
