Family Togetherness

I'm married 2 small children, my parents only had me and have passed away. My wife is likewise an only child, her father departed when she was 15 and hasn't kept in touch. My wife was hurt in a traffic accident and was in hospital and then laid up in bed for 5 weeks at home. Her mother came to look after her and the children, my wife had been in hospital for 8 days before coming home. So, we weren't having any sex and it wasn't on my to do list either her wellbeing was my only concern. Her mother arrived 3 days after the accident and helped with the children. A week after my wife got back home, her mother joined us in our bed, and we had sex. My wife had decided to ask her mother to give sexual relief and her mother had agreed. Her mother still sleeps with us now, even as my wife has fully recovered, and threesomes are now a part of our sexual relationship. I'm quite happy with the family togetherness.
