Night Terrors

Short version, my sister Angelina 24 had always had nightmares from a young age. Angel for short is short for her age at only 4'2" in height. Over the last ten years or so her nightmares deceased, but didn't go away entirely. But they had become a rare event, then our mother Rhonda passed away suddenly and Angela started having them again. I'm George 28 her only brother and as her only sibling living near to her. She moved with me on the passing of Rhonda, I'm single 5'11" skinny. Our other sibling Jessica 31 is married and lives on the other coast. I had got my own place 6 years earlier from a lottery win and Rhonda moved to a smaller cottage after the death of our father James. Angela had been still living with Rhonda when she died of a heart attack. Due to the estate being shared between the three of us, the cottage was sold. Angela had already moved in with me after Rhonda's death. As she didn't like living alone, Angel is short and slim. Well proportioned for her size, due to her height she has some trouble getting clothes to fit her properly. She works as a receptionist near where I work and I had always taken to and from work. Angela doesn't drive and has to catch buses if I'm unavailable to take her. I still have a fair amount left from my lottery win and was looking to move to the country, but I stayed close to Rhonda and after her passing started looking for a place out in the country to live. But with Angel, moving in I wasn't looking hard just browsing. Then back in July, we had a series of thunderstorms come thru and this caused Angel nightmares and she would come running and getting into bed with me. By August she would just be getting into my bed without there being a storm around. I didn't mind this but had started to get hard-ons regularly and to masturbate in my bathroom after she had gone to sleep to relieve myself then near the end of August while I was relieving myself in my bathroom. Angel walked in on me catching me masturbating, she a quick giggle and used the toilet and left. I was a bit ashamed by being caught by Angel, on my return to the bed. Angel gave me a cuddle and I tried to go to sleep, shortly after I had another hard-on and so I started to get out of bed to take care of it. Angel asked what was wrong, I said I needed the toilet. She reached out and felt my groin area grabbing hold on my hard cock. Then asking had she given me the hard-on, I sheepishly replied yes. She told me to lay back down and she would take care of it for me. I did as she said and she started to stroke my cock and spit on her hands to lubricate them. But she ended up sucking me off and I told her I was going to cum and took it all in her mouth. After a while, she told me that any time I got a hard-on she would take care of it for me if I wanted her too. I replied I will always get them now after what you just did. She replied I'm happy you liked it and then cuddled up to me again and we both went off to sleep. The following weekend on Sunday morning I awoke with a hard-on asked her if she would like to take care of it. She smiled and said okay, as long as I took care of her as well. I asked what she wanted and she wanted me to lick her out, while she sucked me off. I agreed and after I had again blown my load into her mouth and she had also come as well. I was looking at her and she asked what I was thinking and I said I was wondering if you would let me fuck you. She replied We might as well, we've done everything else. So I fucked Angel and have been fucking ever since. She has missed her periods and she is having a test done next week to see if she is pregnant. I have now started looking for my country home more vigorously and Angel helps me look.
