Being the Quiet one paid off

I'm the middle child of 3 and the one who stands back and never pushing myself forward. After university I trained as an IT specialist and that help me stay in the background, the others pushed themselves forward and I quietly worked in the background. I came upon a secret in my family just by chance, my grandmother on my mother's side was of the social elite and still great looking at her age. She went to all the A list events and was always in the social columns of the newspapers. But my grandmother was having an affair and it would destroy her marriage and social standing, if it became known. I saw her with her lover, and he was a well-known identity who was married and also couldn't afford scandal. But it just happened to be the same day the press reporters were around, and my grandmother was cornered with her lover. Being caught together would've been bad for them both. But I was also there, and my grandmother had just seen me before seeing the reporters. She quickly had me join them and so could pass it off as something less harmful. Once the reported started asking their questions, she said she was having dinner with her grandson and her friend had joined us. Being a quiet person, I said nothing, and they left separately. I lived close by, and my grandmother accompanied me to my apartment. She intended to stay a short time then catch a cab home. But she had to stop me telling others family members, especially her husband. As I was a quiet person, I didn't have a girlfriend or had any sexual relationships to that time. So, her cuddling me caused me to get aroused. I might be quiet but I'm not dumb and had realized why she was with her friend, not use to being cuddled and knowing of why she was with her friend. I got aroused and she the bungle and decided I assume to use it to her advantage. My grandfather was away as per usual, and it had started raining and so she stayed the night with me, she took my virginity and decided to train me to service her better. I was a little shocked at first, but it had passed quickly, and I enjoyed fucking her. As it turned out her lover moved on from her for someone younger and was caught by his wife's lawyers months later. So, without her lover and a willing student, I became her sex toy so to speak. It also made it easier for her as there was no need to hide from the press or anyone else. She would come into the city and do shopping or whatever she wanted to do and stay the night with me. Draining my balls most times, but everything comes to an end at some stage. After 2 years she had a minor stroke and she stopped visiting me. So, I left with no sex partner, and I thought that was it sexually for me. But my mother's sister started visiting the city on shopping trips and was caught by a bad weather front and unable to home. My mother told her to stay with me as hotel rooms were all booked out quickly and my mother called me to tell me her sister needed a place to stay the night. I had no choice but to accept, but it wasn't a worry to me either. My aunt took after her mother and my mother took after her father, also being divorced and not in a current relationship. Meant she was horny, I soon found out she liked younger men. Being passed past having children, had only increased her appetite for sex similar to her mother. Short version she fucked my brains out and is my current lover, nobody at her home to worry about means she visits for days at a time. That's how it is now, I regularly fucking my aunt and miss fucking my grandmother.
