Labeled as Troublesome

At 20 I was labeled as being disruptive and unruly by my father and mother, supported by my siblings. Luckily, I didn't need their support to survive, I'd a trust fund left to me by my father's father. He had passed away in 2021, and I on turning twenty got access to my trust fund, he could see I wouldn't be going to college and made an allowance to allow my access. Which stopped my father from stopping my access to my trust fund, with both his parents gone and my mother's father also gone. I'd only my grandmother thru my mother left, who was a straitlaced lady as she was always descripted. I'd little to do with her until I moved to the state she lived in, mainly to get away from my parents. I hadn't intended to stay with my grandmother 60, thought I would drop by before finding a place to live and a job. But she insisted I stay with her, said I could come and go as I wanted with any fuss. She lived in an upmarket apartment building and had a housekeeper come three days a week. The first month I settled in and wasn't hassled by her in anyway, it suited me to live with her meals provided and laundry done. I stayed out all night several times no questions on my return, so I was happy to stay with my grandmother. One night I came home late, had a few drinks after work and played pool. Things that would cause my parents to have a fit, my grandmother said nothing except asking if I was hungry. I was so she started to make me dinner while I'd a bath, I came out to eat in just a bathrobe. I ate my dinner and had the next day off, thinking what I should do, I didn't notice the bathrobe had opened revealing cock. My grandmother saw my cock and straight out me was I wanting sex, which shocked and aroused at the same time. My grandmother hadn't had sex since before her husband had passed away in 2019. She looked good for her age; my cock thought so and showed it approval by going hard. I just nodded thinking she was teasing me. She then said OKAY my bed you can stay with me tonight, her only request was for me to take easy till she got used to being fucked again. She was better than any girl I'd had in my life so far. Didn't just lay there, she was active and a very good fuck. Twice before we fell asleep and again on waking in the morning, sex with her has become regular, doesn't intrude on my love life such as it is. I don't yet have a girlfriend, just girls who like to fuck every now and then. But my gran is always willing to drain me, even if I'd got lucky on a date. Only time we stop sleeping together is when my mother visits, rarely with my father which is somewhat of a blessing. Now just turned 22 still living with my gran, no plans to move out anytime soon.
