“The only thing is” I added, trying to find the right words, “I like… I mean, WE like… me…, you know.”My wife was looking a bit puzzled....��You know” I said, “Right after Dave… ““Oh!” giggled my wife, “I get it! Well, we can make that work, I’m sure.”She texted Dave some more, indicating that we were on for later. He texted his address and then we finished our lunch. As we ate and chatted, my leaned in close.“So” she said playfully, “You really enjoyed… you know,.. right after Dave?”“I did”. Again I looked but didn't see anything. I finished and got dressed and went to work.A couple of days passed and I was again naked in the bathroom shaving. I heard something again but this time I had the mirror tilted so I could look at the door without turning my head. I saw what I thought was movement and a shadow. I thought to myself that the only one it could be was Shelly my 18 year old step daughter because everybody else was already gone to school or work and she and I were the only. I knew she loved me as much as I loved her, but for her to act this way had me totally stumped. I thought back on our brief courtship and all we had said at the ceremony. I couldn't figure out why she would act the way she had and with no regard for my reaction. This was not the Kat I knew and fell in love with. I decided to head back to the house and see if, after having had time to think, Kat could shed some light on the way she had been acting.I hadn't realized I had driven so far last night. She loved foreplay, including oral, both giving and receiving. The first time she sucked my cock I thought I had died and gone to heaven. I even got to liking going down on her. She provided me with all the things I wanted, but my wife had refused me. She topped off my learning curve by letting me fuck her ass. She may have been 53, but this was one very sexual woman. Don’t get me wrong, I loved my wife and still desired to fuck her, but I needed more. Much more. Over the years I repeatedly.
