My Sister-in-law

This all started in 2015, my wife had died 2013 leaving to care for our 2 boys than almost 5 and 3. My sister-in-law was suddenly hit with divorce papers by her than husband. Which came as a total shock to her and left devastated and she started drinking. I was the closest relative to her at the time and I worked from home and cared for my 2 boys and now had a drunk sister-in-law to take care of as well. My boys go to a play group for several hours Monday to Friday to allow them to meet other children. I had to go and check on my sister-in-law and after dropping off my boys I went to her apartment. She was a wreck as was now usual and only partially dressed, I hadn't had any sex since my wife's passing. With her cuddling into me crying about her marriage breakup, I got aroused and took advantage of her. Fucking her twice and after we showered together, at least she wasn't crying anymore. I had to go to pick up my boys and she didn't want me to go and leave her alone. I told her I had to go, but she could pack some clothes and stay with me and my boys for a while. She quickly packed a few things, and we got the boys and then back to my home. My sister-in-law was sober and really enjoyed staying with us and sharing my bed. Time passed and the divorce was finalized, and she got a lump sum payout and the apartment. Her husband told her that he was marrying again in a couple of weeks, which I think he thought would upset. To which she replied she has my condolences, which shocked him. He was 12 years older than her and 6 years older than me, she had already moved fully in with me and my boys and so sold the apartment. We continued fucking regularly and I never thought of taking precautions and she never mentioned anything about precautions. So, it was a bit of a shock to me when she started having morning sickness, I'd seen my wife going thru the same thing with our boys. Then I found out that she hadn't taken any precautions or even thought about precautions or about getting pregnant herself while were having regular sex. It shocked her she was pregnant, but she got over it quickly. Faster than I did, but I couldn't just reject her after the way she had acted after being told she was being divorced. I also like the sex I was getting, and we decided to marry and made both sets of our parents happy. One thing that made them happy was my sister-in-law/wife was having a girl which made our mothers very happy. Their first granddaughter. The shock of us marrying was dispelled quickly as they hadn't realized we were having sex or in any relationship at all. Now we are happily married with 5 children 3 boys and 2 girls. Only major change was we moved back home closer to our parents. My boys love their aunt/mother and their new siblings and the dog we have gotten also. My first wife's photos are still on display, and I still miss her dearly. But I also love her sister greatly as well.
