I overheard

I'm Arthur 22 live at home with my parents and my sister had married. I was home as usual for me on a weekend and I decided to get a snack, as I headed for the kitchen I heard my mother Alison 47 talking on the phone to her older sister Susanna 50 and they were talking about sex and I heard my mother say so your not getting any sex of John (Susanna's husband) and your sick of masturbating yourself. That stopped me in my tracks and stayed to listen further, anyway I now knew my aunt Susanna was really horny and wanted fucking. As a virgin myself I wanted fucking also, I went back to my room and thought about how I might get Susanna to fuck me. No good idea came to mind. Later I was going out to see who was around of my friends as they were usually at the lake with girlfriends on the weekends. But there was usually one or two still home. I was asked by my mother was I going near Susanna place while out, I said yes I was, but wasn't really going near her place. But why not you never know your luck, my luck was in as Susanna was drinking and I'd brought a box from my mother to her. She opened it in front of me and it was a electric dildo. I was shocked at first and Susanna wasn't ashamed at getting it out in front me. She just looked at it and I said I should as she might need need to be alone. Susanna said I would rather a real one, I decided to risk it and asked are you asking me to help. She was shocked this time and looked at me and said finally are you willing. Yes I replied but you'll have to teach me, with that she shut the door behind me and took me to her bedroom. She taught me to fuck and she really drained my balls and I've been visiting her ever since. Alison seen Susanna improvement and realized it wasn't the dildo doing it. But at a Christening of my sister daughter, Alison seen Susanna talking to me and staying very close to me. Putting two and two together she realized I was servicing her Susanna. Susanna went away for a holiday and I was at a loose end, home with Alison as my father away playing golf. I was sitting reading on my bed and Alison came in stark naked and asked to be given everything I gave Susanna. I'm still fucking Susanna and also Alison, keeping it in the family.
