Wife's Little Sister

I told my wife I have had a fantasy for a long time about having a threesome with her and her little sister; my wife is forty-four and her sister is thirty-eight and so hot. I had a shower one evening while my wife said she was getting ready for bed. I went in the bedroom still wet with a towel around my waist to see my sister-in-law totally naked on the bed. My wife came in behind me, pulled the towel off, and what a night we all had. Big thank you to my lovely wife.
