My 36 year old wife doesn't know that I have been fucking her 24 year old sister since before we were married ten years ago. Yes I know she was 14 at the time. It was her idea.

I married my wife not because I was in love with her but because she proposed, offered me a very expensive diamond encrusted signet ring and gave me a trust fund to yield a nice allowance and all I had to do was fuck her once a week and be her escort to various functions from time to time and oh yeah get her pregnant. The plan was she takes care of her family business where she is the CEO and I am the house husband who takes care of raising the kids and keeping house. Not bad. She has long hours and gets home around 9 at night most of the time. Her little sister practically lives here though technically she lives with their retired parents. As soon as my wife takes off for the office (six days a week) little sis pulls up in her little sports car and struts in, knocks me down on the bed rips our clothes off and we fuck like teenagers. Yes I take care of the kids and do all the household chores like a good house husband but You'd be surprised how much less time that takes compared to what my wife thinks it takes since she never did housework before. I get at least two hours a day to fuck my wife's sister and occasionally a friend of hers who joins in.
