Riding my Aunt's Ass

My Aunt Cheryl 39 single took me in when my parents died 5 years ago. My father Alan (Cheryl's brother and only sibling) was 5 years older than Cheryl. My mother was an only child and so Cheryl was the only family I had. I'm Barry 21 and still live with Cheryl, I had been trouble for her at first. But had calmed down over the following couple years and settled into life with Cheryl. Cheryl didn't date and I hadn't seen her with anyone male or female much at all. Than last Christmas she came home from a work Christmas party under the weather (drunk). I on the other hand was on call for my job and couldn't drink and was sitting watching TV when Cheryl came in the house. With a taxi driver wanting his money, I paid him and he left. Cheryl sat on the lounge half asleep, I decided to help her to go to her bed. Picking her up and taking her to her bed, when she grabbed hold of my cock thru my pants. Squeezing it and telling me she was very horny, I do okay with girls. But no ladies man and with her squeezing my cock it went rock hard. By the time I laid her on her bed, I was horny also. With her wanting sex I decided why not and started to undress us both. Once naked she went straight for my stiff cock and was soon sucking it. I blew into her mouth and kept my cock hard and decided it was time to fuck her. I started fucking her and as I felt my cum rising, I thought I shouldn't cum inside her. But I really wanted to leave my cum inside also, so I changed from her pussy to her ass and continued fucking her till I came inside her. Then laying beside her for a while and then going for a shower, on returning to her bedroom she was fast asleep. So I covered her with a blanket and went back to watching TV. I wasn't called that night and in the morning I was making breakfast, when walked totally naked into kitchen and asked me had we had sex the night before. I said yes you really wanted a fucking and so I gave you a fucking. She then asked had I cum in her, yes I replied and added only in your ass. Good I'm not on the pill she answered, I walked up to her and gave her a cuddle and said anytime your horny I'm your man. Thinking she would be a bit shocked as she wasn't much drunk now. Good she said, adding maybe we can have another fuck after breakfast. I smiled and nodded and ever since she sleeps with me almost every night. She is also pregnant and we think that there was still some sperm in my cock shaft after she had sucked me off or maybe I came a bit before changing to her ass. Anyway test show the baby boy is healthy and she is having him. I'm still dating girls and regularly fucking Cheryl.
