We had a small get together at our home several months ago and invited all of the people that work in our small office. One of the ladies the came is a 60-65 year old lady named Myrna. She and my wife hit it off right away and have become very good friends. My wife is 47 and out sexlife is very active. I noticed that Myrna was taking off a lot in the afternoon supposedly to care for grandchildren. One day I have very little pending so I took off early and when I got home Myrna's car was in the drive way. I walked in my living room and found my wife, nude, splayed out on the couch and Myrna fucking her hard witha strap on. She kept saying "you love grandma's big dick dont you?". Needless to say I fuck them both.
