She's 68 years old and is always wet

I have known her for a lot of years and a few months back she came over and she wanted to talk. I'm the only one here so in she came. She got a pop out of the fridge and she was in a dress and sandles. She asked me if I ever butt fucked my wife? Yes I do and she was I really like to get fucked in the asshole. Then she stood up and stripped completely nakid and said let's go to the bedroom. So she had a small dildo and it was in her asshole. She pulled it out and I grabbed a 12"x2.5 inch thick glass tube. She was staring at it and said does she take it all? Yes she does and I got the harness and put it on and I told her to suck it and she slid it down her neck. And was pounding her tonsils.then I told her to turn around and I put some lube on her asshole and the tube and it always slipped right in to her asshole and it slipped all the way in. I just held it in her asshole and she was rubbing her tits and I started to fuck her slow at first the fast. She was on the side of the bed and she was moaning loud and she came 4-6 times in about 10 minutes. Then she got up and lays on her back and is holding her feet up and I started asshole fucking her butt hard and she came a lot then she squirts on my chest. I pulled it out and I washed it off and I was going to pussy fuck her but she said no my mouth and she lays her head back an the tube is making her neck bulge as I was going in. She then pulled her head back and she said pussy fuck me with your cock. I fucked her hard for a while and when I was going to cum she said in my mouth and I held her head tight and I came in her swallowing mouth. She then sucked my nuts and when I was cuming she stuck in a finger in my asshole and I squirted a lot of cum. She just laid there when I was done squirting my load. It was a great day and she stayed late and she ate my wife's pussy.
