Lonely Aunt

My uncle Patrick 47 died in car accident; he was my father's younger brother. He was married to Emma 39 a quiet woman by nature not bad looking either. Left fairly well off by Patrick they had no children of their own. I'm the closest relative to her, had my own house 3bedrooms 1bath and at 32 I wasn't in any relationship at the time. Emma lived in an apartment which she owned, but she was lonely. Her life had been concentrated around that of Patrick, with him gone she was lonely. With only me her being comfortable around with Patrick gone as we had been together a great deal when Patrick was alive. I run an online business and work from my home, so Emma started visiting me daily. I knew she was lonely and her nature and liked her being around. One day she asked me would I mind her living with me instead of her staying in her lonely apartment. I was a little shocked, but soon realized it was her quiet nature that kept her from meeting new people and living with me she would meet more people overtime then if she stayed by herself. I agreed she sold her apartment and wanted to pay me for letting her stay with me. I refused as she was doing the housework and even my laundry. I'm a fairly tidy person, but housework isn't a high priority with me. I also like trekking get out of the city and walk thru the hills and camp out, I try to do it at least twice a year. I planned a 4-day trek just for a break mainly, told Emma of my plans and she seemed a little depressed next day. I ask her what was wrong, and she was unsettled about being alone again. I quickly realized I was like her security blanket; she could come along if she wanted too. She brightened up straight away. The next day when we were grocery shopping, I helped her pick out what she would need to go trekking. Clothes and footwear mainly, I already had a tent which was big enough for two along with a spare sleeping bag. We went on the trek, and she really enjoyed it and so did I, having her with me. My next trek was going to be ten days, in the fall, I like the crisp air of that time of year. I'd told of my planned trip, and she was eager to come along with me. I foresaw no problems, as we had none on our first trek together. As it got closer another shopping trip to get warm outdoor clothes for her. As it can get really cold sometimes, when the trek came around, we headed off together. First two days were fairly easy, and we made good time, we awoke the third day to a very cold breeze blowing and light rain falling. I check the weather on my stat phone, and it would pass over us by days end. We decided to stay put and wait it to pass over us. Huddled together in a small two-man tent was cozy, and one thing led to another, and we became lovers. She thought she couldn't have children as Patrick said he had been tested, and he was okay. But she never got tested, I should've realized Patrick was a person who would never admit to a weakness. Can't father a child would've been a major weakness in his mind, as it turned out he hadn't got tested at all. My first clue was Emma getting pregnant, then asking Patrick's former doctor about any testing he had had. No such test the doctor knew about, he could've gone to a special clinic. No such information in his papers Emma had. Emma was happy to be becoming a mother, I was at first shocked. But grew to love the idea myself, as did the wider family. We got on very well together and so I married Emma. Now three year later we've 2 children a boy and a girl. Unlikely Emma will get pregnant again, but it won't be from the lack of sex. She is very willing to please me, as am I about pleasing her. In our sexual relationship we've never taken any precautions. Emma is a great mother and perfect wife for me.
