Miriam

I'm Alex 37 divorced 2 children, my left for overseas and I got full custody of the children as she didn't even contest it. But I was having trouble managing work and caring for the children, I found hard to get a housekeeper who would care for them when I was working. My sister Miriam 39 divorced for 4 years with no children, had her house purchased for the widening of a highway and she came to live with me in October last year. She started to look after the children and take care of my home, Miriam is average in height, weight, and looks and has an online business that she runs from home. In March at our parent's wedding anniversary, we attend with our other siblings and due crowding we stayed in the local motel together. We got back to our room just after midnight and after putting the children to bed. I had a beer outside the room and Miriam went for a shower before bed. On finishing the beer I needed to pee and went straight into the bathroom where Miriam was drying herself. She didn't mind me entering and using the toilet but commented on my cock size saying it was a lot bigger than her ex's Donald's cock. I replied Ruth never complained about it when we were married with a big grin on my face. I don't know whether it was all the beer I had drunk that night or I was just horny. But I said I'll give you a fuck if you want before I realized what I had said. This was a shock to both of us at first, but Miriam was the first to respond and said why not I could use a fuck. This was another shock to me, but I still accepted her acceptance. We went to the bed and I fuck her, in the morning we were still together and both naked when we were awoken by the children. They didn't say anything about us in the same bed and I got to get a bag from the bathroom for me and while they were gone I got up and put some pants on. On their return, I took them outside to allow Miriam to get up and dress. About an hour or so later after everyone had showered, we went to a local diner for a late breakfast. Then over to our parents for lunch and another family get together. Miriam kept giving a sly smile and while the children were playing with cousins I got aside alone and asked what she wanted. She said she was thinking of the fucking I had given her the night before and was hoping for another. I said Anytime you want I'm yours, but not here at this moment. Later on my brother David asked could my children stay over at their place with his children for a sleepover. I agreed and Miriam about it and said if you still want sex tonight is your lucky night. After we had been out to dinner with everyone and then got back to our motel room, I asked Miriam was she still willing to have sex with me. Yes was her reply and we showered together and had sex several times during the night and again in the morning. We went over to our parent's place for lunch and got the children there, after lunch, we headed back home. We got home 3 hours later and decided to get pizza for dinner. That night Miriam slept with me and every night since the children haven't noticed it or if they have they haven't mentioned it. But they are only 5 and 3, were all very happy together.
