My wife enjoys my sister's company, they consider each other friends. My wife doesn't know that I know she and my sister have been having a lesbian affair for five years. I know because my sister sometimes films it and sometimes arranges for me to peep on them. My wife doesn't know that I've been having s** with my sister since I was 12 and she was 10 - 25 years now.
Last week, we had the greatest moment. My sister and I planned it out very exactly. I had a nooner with my sister at my place. When my wife came home, I was hiding in the closet and the two ladies had s** with my wife eating my sperm out of my sister's puss. After they finished, my wife was distracted long enough to let me get out of the house and pretend to come home. I had my wife right there in the living room with my sister watching "secretly". After I did her, I left the room and as my sister "snuck out" I heard my wife apologize to my sister for "having had to see that"!
It's a load of fun, and I look forward to seeing my wife's face when she discovers what we've been doing to her.
