Mum-in-law was divorced and seeing someone now and again. Margaret (mum-in-law) was not bad looking and like all guys always wondered what it would be...like to fuck their wifes Mum.At the time I worked nightshift and as I was getting home wife was getting ready to go into Office for a days work so it was just a Hi and goodbye. Margaret only worked a few days a week so was home for a couple of days a week.I thought of a plan for Margaret to walk in on me having a wank and in my mind I would end. ”“I liked that game. Can we play it again soon?”“Sure but you’d pick the number ten for sure! I’ll write down a bunch of numbers on small pieces of paper and the number you pick is the number of men you have to make cum.”“I can hardly wait!”“We’ll see what we can do before our babies are born or into December.”“Soon please,” she sighed relaxing in his loving embrace.“Would you like to go home or try to make it a total of ten men? I know that Wendy and Tina would be happy to taste your pussy. She lifted her ass and moved her body to ease the penetration. I fucked her in the missionary position for 5-6 minutes. Then I asked her to turn and be on all fours which she obliged immediately. I grabbed her ass cheeks. They were so soft and smooth. I squeezed and parted them a little so that her butt hole is visible. I wanted to shove it in her ass but she was afraid to do so. I also thought rather than making it a forced sex let’s enjoy. So, I made her lean forward and raise her butt so. Thomas pulled away from Amy and reached his hands up to the thin straps across her shoulders. He heard her moan as he slowly pushed them from her shoulders and let the dress fall to her feet.Amy gasped when she stood naked in front of Thomas. She had never been totally naked in front of him before. Somehow, she felt even smaller standing in front of his large frame. He loomed over her, his hands gently touching the soft flesh of her arms. She trembled.Thomas bent his head and kissed Amy again,.
