I'm a horny old man

I'm Andrew 64 retired widower and have 2 grown children who never visit me since my wife passed away 6 years ago. I'm like sex and have been having relationships with women for about 4 or 5 years but not interested in a relationship with them just sex. That changed in 2020 when the pandemic started and I was alone in my house and got a call from my sister (only sibling) Karen 60 divorced 1 child a daughter Kerry-Anne 30 single, she called me as I lived closer to Kerry-Anne then she did, Kerry-Anne had lost her job at a travel firm and wouldn't be able to afford her rent without a job. I agreed to have Kerry-Anne stay with, I hadn't had much to do with her over the years. Anyway she came to stay with me, Kerry-Anne is average in looks and body shape. I'm nothing special myself, then a lockdown started and we were alone all the time. Boredom or just lust led to us fucking and Kerry-Anne got pregnant due to a weak condom. I wasn't worried as you don't always get pregnant from one fuck, but Kerry-Anne did as tests after the lockdown showed and later tests showed the baby to be healthy. Kerry-Anne wanted to have the baby and I said I was okay with that. Karen was at first shocked that her brother got her daughter pregnant, but it was done and so accepted to support her daughter. She also moved to live with us, but didn't stop us sleeping together. But after several weeks joined in the sex with us. Kerry-Anne had daughter she called Karen after her mother and we've continued living together ever since, Kerry-Anne didn't take precautions after the birth either and was leaving it luck whether she got pregnant again. Well she did last month was confirmed as pregnant again. The three of us share the same bed and will as long we want too.
