I'm not really sure what category this belongs in. I'm a 33 year old guy. I got married when I was 23, and my wife was 20. I had met her online, and wound up moving about 1,200 miles from home for us to be together. People back home were not thrilled with my decision. Our marriage was pretty great in general. We've got 2 wonderful children. This past June would have been our 10th year together.

5 years ago, my wife died in a car accident. I was crushed, to say the least. Still, not a day goes by where I don't miss her.

I was not ready to be a single father. I may have been 28, but I've always been a bit behind as far as adult responsibilities go. Hell, I didn't even get my drivers license until I was 26. Anyway, all of my side of the family still lived 1,200 miles away, and I already had a good job here and wasn't going to rip the kids away from family here. My mother in law ended up moving into my house with us, to help me out. The kids always enjoyed time with grandma, anyway. She helped me out a ton. She was also already going through a nasty divorce from her husband, so she was looking to move already anyway.

We developed a normal routine just like a normal family. I mean, I was a complete head case, depressed, and an alcoholic. But things with the kids were good. My mother in law didn't like me drinking so much. Or really, at all. I started going out and drinking, instead of doing it at home. I think it went like that for over a year.

Then, on the day that would have been my wife and I's 7th anniversary, something happened. I was having a particularly bad day, and after the kids were asleep, I was going to go out an and drink. Only, my mother in law tried to stop me. I wasn't really having of it. I was just waiting for her to finish preaching to me and then I'd go get shitfaced. When she was done, I told her that I was going to go. She asked me "why don't you just stay here with me instead?"

I politely told her I didn't really want to do that. I'd much rather just go out and drink. She pleaded with me to "just stay here with me. It'll be fun." And then she did something I didn't see coming. She sort of tugged down on her shirt by the neck, to show off and bring my attention to her cleavage. Not that she needs any help drawing attention to her tits. They're quite large.

I went silent. I didn't know what to say. I just kind of stared at her, probably looking very confused. She said "come on... you mean, you've never thought about it? We spend all this time together here and you've never even once been tempted?"

The truth was I had thought about fucking her from the day I met her. She's a good looking woman. She had my wife when she was 19. She was 46 at the time this happened. She's short and thick. Great curves. Looks pretty good for her age. But I had never actually given thought to the idea that she'd be interested.

I told her "yeah, I mean I guess. Physically, yeah, I'm very attracted. I just hadn't thought about actually doing it, you know?"

She smiled, and told me "well why don't you stay with me, and you can think about it. Because I've thought about it enough already."

I stayed. We sat on the couch together and watched TV. We sat and touched and flirted like teenagers. Eventually it got more serious and we started to kiss, and then grope, and then it was full on making out. I hadn't had that feeling or excitement in a long time.

We didn't really say much. There was no need. We ended up going to my bedroom, and quickly got off our clothes in between playful kissing. I ended up fucking her pretty much right away. Not much as far as foreplay goes. I slammed her deep and hard, as she struggled to keep her noise down. I pulled out and shot on her stomach. I knew we weren't done. We made out for a bit again and then wound up 69'ing, with her as the top. I ate her until until she had an orgasm, and then started to fuck her again. She seemed genuinely surprised that I wanted to keep going. "Sorry, I guess I'm still used to Tom" she said, laughing in a reference to her ex-husband.

This time it was a more slow, sensual fuck. We kissed a lot as I drove deep but slow. Eventually, I did pick up the pace and start to fuck her hard and fast again. She asked me to stop, and I nervously stopped and asked "what's wrong?"

She asked me "Nicholas, do you... do you want to have any more kids?"

I actually hadn't thought about it at all since my wife died. My first reaction was "hell no, I'm done."

I told her "I don't know. Why?"

She told me "I want one more. And I'm almost out of time. I'd already be very high risk if I got pregnant. But I want one."

We were both just kind of silent and still, probably for a full minute, my cock still inside her.

She broke the silence "it's okay. You don't have to. I'm sorry for bringing it up. You can think about it if you want to."

I ended up pulling out of her and calling it a night. She left the room and went to her bedroom. My mind was racing. I knew she was disappointed, but I really had to think about it. The truth was, yeah, of course I wanted to cum inside her. But did I want to have a child with my wife's mother?

By the next day, I had already decided.

We were pretty quiet in the morning and then only general interaction while the kids were home after school. After they went to sleep, Marie (my mother in law) took a shower, and then told me she was going to head to bed already, to get some good sleep. I knew that was probably bullshit, but it didn't matter. It was actually helpful to me, because I fully planned on fucking her again. I waited until she had been in her room for a few minutes. Then I got down into just my boxers, and quietly entered her room. She was actually falling asleep already, but she woke up quick when I climbed into bed with her. She was just wearing a long nightie and panties. She slid off her panties, knowing full well what I was there to do. She started to rub her pussy as I leaned in and kissed her and squeezed her tits. Barely any time had passed before she said "fuck me, Nick."

And so I did. Pretty much fast and hard until I was ready to cum. I told her "I'm going to cum." She didn't say a word. She was just waiting to see what I did. I stopped for a bit to buy myself some more time, and I fingered her clit with my cock still inside her until she came. Then, as she shook from her orgasm, I pumped her pussy until I started to shoot my cum inside her. She wrapped her legs around me and yelled "oh my god yes!" We laid like that for a bit, her legs wrapped around me. We kissed some and grinned at each other like idiots for a while, lol, marveling in the very naughty feeling of what we had done. This was a woman who tried her hardest to get me to accept her as "mom" while my wife were still alive, after all.

When we broke our embrace, she took my cock in her mouth and cleaned all the juices off, and blew me until I was good and hard again, and then I turned her around and fucked her doggystyle, which she particularly enjoyed, until I came inside her again.

Things changed for us that day. That was the day my mother in law and I started to share a bed and pretty much act like a married couple. We hid it from the kids for a while, for the most part. But we sure fucked a lot. When we did find out she was pregnant, we took our time and eventually broke the news to the kids that grandma and daddy were having a baby. They were going to have a little brother. My oldest seemed to know something wasn't quite right about this scenario, lol, but as time has passed, it's worked out fine. And now they all call her "mom". I fucked my new "wife" throughout her pregnancy, to both of our enjoyment.

We still live like we're a married couple. We'll never get married. The reactions we've gotten from family and friends alike has been bad enough. But I don't see us stopping being a couple any time soon. We're very close and actually make a decent couple. And we still fuck a ton. The sex has always been great. She can't have kids any more, which is fine by me.
