My wifes S, that was easy!

I have always been attracted to my wife's S. She is 53 with C cup tits, tight ass, very tan, blonde hair, not to long just perfect. Perfect build not thick at all but not super skinny. My wife is a D cup and is thicker but has long blonde hair, and is candy coated. They both have thick juicy lips. My wife knows that I have always wanted to fuck her S, but it was just always a fantasy. It didn't bother my wife because she knew it would not happen because her S is not a very sexual person. She had been divorced twice and both her husbands complained they did not have enough sex. This drove me crazy, a chick that hot not being a fuck machine was hard to believe. My wifes S was living in a house in the same town as us and I stopped over their one day to grab something. I noticed her car was their but when I knocked no one answered. I walked in figuring she may be in the pool, oh I was hoping I never got to see her in reveiling clothing, ever! One time at a wedding she wore a mini skirt and my cock was so hard I couldn't stand up when she came over to talk to me. I didn't see her by the pool and as I walked around the corner I caught a glimpse of her in the other room, she was on the phone and not happy. What through me off was her out fit. A red mini dress with red high heels and black stockings, with red bright lipstick. I almost came in my pants as Iooked at her. On the phone she was talking to her boyfriend and said. "That's fine I wont come to the wedding if your ex is going to be a bitch, but your missing out because I was going to fuck the shit out of you" I almost passed out, I had never heard her talk that way. She said she was going to hang up and go lay by the pool. I quickly went outside and hid behind some bushes hoping to get a good look at her in her bikini. She came out with a two piece bikini on and sunglasses on. She layed back on a chair and I noticed her reach into her purse and she pulled a out a huge dildo. I couldn't believe it. She started slamming the dildo in and out of her pussy, she was moaning and saying fuck me harder as she slammed it in and out. At times she pulled it out and sucked it,licking the head cleaning her own pussy juice off. I could not believe this was the same women I had known for 20 years. Finally I had enough. I walked up beside her as she slammed her dildo over and over into her pussy. She finally noticed me, my hard cock right next her her mouth. She quickly pulled the dildo out and started to say something, but I put my hand over her mouth and put my finger to my lips like say quiet. I then slowly put my cock by her mouth and she took it down her throat slowly, sunglasses still on she continued to suck my cock going faster and faster as she fingered herself, I was a about to cum, so I flipped her on her back and power fucked her on the chair with her legs spread apart as she screamed fuck me, make me cum, I could feel her wet pussy as it made splashing noises as I fucked her. Finally I got up and she sucked my cock as hard and as fast as she could, I pulled my cock out of her mouth and shot cum all over her face and glasses. She never said a word, just jumped in the pool to clean the cum off and I went home. I guess she isn't so innocent after all.
