“Sure, honey and I have something kind of embarrassing to ask you too.” Margaret replied, “but you go first.” I thought I had better hear what she had to say first before I ask her because if she wanted us to stop having sex, my question would be a waste of time. “Ladies first” I said smiling.
Margaret came over to me and sat in my lap facing me. I could smell my cum still on her breath. “Well.” She said staring into my eyes “I want you to fuck my arse.” I must have looked shocked as she then added “only if you want to. Sorry if I shocked you but I really like it. Sorry hun.”
I then smiled and hugged and kissed her. “Sure.” I replied, “but I’ve never done it before.” She told me it’s the same process but at a different level and we both laughed. “Ok. Your turn” she said.
I then told Margaret about the conversation at work, that I told then she was an ex-work college I was having sex with and they all suggested that she joins them for a lunch sex session. She looked at me for a while with her eyes wide open the held each side of my face in her hands. “What do you think? Would you mind?” She asked. I was completely honest and told her the idea turned me on, but I wasn’t sure why.
Margaret then hugged and kissed me again and said she would love to and that she’s done it before and with more than five guys. I was stunned. My mother-in-law is a total whore and again it got me hard! Margaret felt my cock, stood up and then took me by the hand and lead me to her bedroom. She went to the side drawer, took out some lube and rubbed it over my cock. She then turned around, bent over and held her arse apart. “Slam me!” she ordered, and I slipped into her arse. It wasn’t as tight as I thought it would be, but it was tighter than her cunt. Here was I at 21 fucking my mother-in-law’s arse and I was loving it!
As I was fucking her, Margaret told me she would fuck all my friends in front of me and take all their cum. This made me blow so hard that I nearly pushed her through the wall. She told me we will do this again, but she wanted to shove a dildo up her cunt while I was fucking her arse. I would have fucked her again after that comment but needed recovery time and I told her that. She told me to hold that thought but as my wife would be home in 10 minutes that we should wait. We both went and washed ourselves to try and get rid of the smell of sex and sprayed the house with Glen20.
The following day I was at home. As soon as my wife left for work, Margaret and I were fucking like crazy. Most of the day she had the dildo in her cunt, and I was fucking her arse. I lost count of how many times we fucked but my balls and cock were starting to get sore and I hardly had any cum left. In between me fucking her, Margaret was working the dildo in her cunt. She told me this was what she did most days before I lost my job. She then asked me about the guys at work and when she was meeting them. It was getting close to 3pm and I told her they would be finishing work soon. She suggested I invite them over. I told her they would be all sweaty and she said she liked that.
