The day my life changed

The day my life changed was in March last year, I'm Kevin 20 and single. On a weekend last March, I went over to my aunt's place to pick up the lawnmower to fix it for her. I'm good with engines and fixing just about anything mechanical, but lousy with women. My uncle Patrick 51 was away working and aunt Beryl 39 (mom's sister) was home alone. But when I arrived I found Beryl wasn't alone as I thought, she was being fucked in the kitchen by a man and she was enjoying it. I found out later it was the plumber and he really gave her a service. I decided to get the mower and leave without being seen but found the shed locked. So I had to wait until the plumber left and the went around to the front door and rang the doorbell. Beryl answered the door in her bathrobe. I asked for the shed keys and was given them and I headed around back to the shed. I had just loaded the mower onto my pickup and Beryl came out and asked me how long had I been there. She saw by my expression I must have seen her fucking the plumber, so she asked me straight out and I told I'd seen her and the plumber. She asked me not to tell anyone about it and I said I wouldn't tell anyone. But I don't think she believed me and then she made me an offer, she would have sex with me if I kept her secret. I got a little excited by the prospect of getting laid and agreed, she took my hand and led me inside the house and to her bedroom. She told me to undress and she rang my mother Karen 43 to tell her I would be home after dinner as I was doing some chores for her. Then Beryl started to run her hands over my body and told me to lay on my back on her bed. She went down on me and then mounted me, she drained my balls twice and told me she would let fuck her when Patrick was away. This was quite often, so I started my sexual training with Beryl and she a very good teacher. When Beryl and Patrick went on a holiday in August I really missed the sex with her. I started checking out my mother Karen and when my father Gordon was away fishing I let Karen catch me masturbating in the garage. She told me I should get a girlfriend and I responded I'm too shy to approach them. Anyway, she decided to teach me about girls and it wasn't meant to t be sexual lessons. But by being slow to pick up on her lessons I got her first to show her nude body and then was able to touch her private parts. Finally, I was able to fuck her and got her off. Thanks to Beryl training and so I was able to fuck her again before Gordon got home from his fishing trip. Shortly after Beryl and Patrick returned and I was soon fucking Beryl again. I also got the occasional fuck from Karen as well, I then met Alice 18 and started dating her and have now started fucking her. But I still visit Beryl and join Karen in her bed when Gordon is away.
