"I don't allow that usually, but I didn't know what to say. I am not a toilet, I tried. But he just looked into my eyes and interrupted me by saying t...at he thought pissing in my mouth would be nicer than going to the toilet."So I went on my knees again and opened my mouth. He stood up and started pissing in my mouth. He told me to drink it all up. As much as I could. So I did, but it was too much, and he pissed all over my face on purpose. My eyes, ears, hair and blouse. Then you came out to. If you insist."She stood, rubbing her already smarting backside, then smiled. "I do insist. But I also insist in repaying the compliment. For every stroke of the slipper you give me now, I get to do the same for you."I'm not averse to receiving from time to time, but I hadn't considered it today. I smiled. I would follow her, I realised, to the ends of the earth. "You're on. Now touch your toes."Without hesitation she bent over. Her reddened backside was a perfect picture. I could only imagine. Then I put my hands on her back and rubbing my hands slowly over her back. I was feeling that her back is very soft like cream and tried to give little pressure there by fingers.I feel her bra strip also and playing with her bra strip by my fingers. She looks in my eyes and gives a naughty sexy smile.Then I got more courage and put my hands on her ass and hold her both side of ass and rubbing my hands hardly. I feeling her ass crack and crushing her ass. She was breathing heavily.Now I came. I knew in the back of my mind that this was the first time my wife had ever been fucked in her ass and she was getting it from the real thing this time in Joes big cock. He straddled her hips so he was above her more and started to really thrust strongly in and out of her while she half screamed and groaned at the same time. Liz brought me back to her as she continued to fuck me. Now, I know I was enjoying what she was doing as I was asking her to fuck me deeper and harder. Fuck me faster was.
