Family Business

I'm Barry 27 married with 1 child, I work for my wife's Judith family company. We all get on very well together. They are all very keen campers and go camping whenever they can. I like camping and enjoy long walks along the trails in the mountains where we go camping. Judith use to join me on the walks, but since the birth of our daughter Grace she stay at the camp now. Grace 53 Judith's mother is a no nonsense type and seems at first to be a snobbish know all type. But I found her to be a very sensual woman, it all started when Judith was in her last 2 months of her pregnancy with our daughter Grace. I had to go interstate on business for the company and Grace (senior) join me on the trip. We stayed at the same hotel (different rooms) and didn't much of each other till the night before our return home. Grace had finished her family business that she had came along to do. An aunt had passed away and she come for the funeral and they had wake after it. Grace was pretty drunk when she got back to the hotel and her niece had called ahead for me to meet them on their arrival. I took Grace to her room and laid her on her bed and left. Several hours later she called on my phone saying she needed my help and I returned to her room. On arriving there I asked what she needed doing and to my shock she replied me and opening her bathrobe at the same time showing me her naked body. Seeing the shocked look on my face she added I'm not that bad looking am I. No I answered but your my mother in law. So we keep it in the family, Judith isn't let you do her at the moment and my Herbert is pass it without his little blue pill she replied. With that she gave me a cuddle a nd started stroking my groin, my cock went hard and we hard sex. I stayed the rest of the night with her, in the morning Grace rang home saying she had to stay another 2 days and said she wanted me to keep her company. For the most part we stayed in her room fucking. We did go to grave site and laid some fresh flowers, on returning home Grace returned to her routine. Except I would get calls to meet her and we would have sex. Then after Judith had little Grace, Judith and I and little grace were taken away by Grace (senior) for break to the family beach house. Grace (senior) on our first night there, with baby Grace asleep and Judith and me in bed together. Grace came into the room totally naked and got into bed with us and she went down on Judith. I was shocked at first, but Judith was enjoying it. Judith told me to fuck her mother and so I done as I was told. We regularly have threesomes still and I've found out that Judith and her mother have been regular lovers for years.
