Fucking My Grandma

I'm Donald 28 and live in the city in my own home I'm still paying off, I moved to the city three years before. I got the house straight away preferring to pay it off than rent. My Gran Thelma 67 lived in an apartment in the same city, about year after my arrival there was a fire in her apartment building leaving her homeless. As the only relative in the city she had in the city she moved in with me. She does the cooking and keeps house for me. I'm not the greatest with women, but do get lucky now and then. I watch porn and my computer and masturbate while watching it. Then pandemic came and during lockdown it was only Thelma and me together all day and night. One day while watching porn in my room, I came across a site where old women fucked younger men. Watching this site gave me hard-on and I masturbated while watching it. I became aware that Thelma was better looking than most of the old women on the porn site and started thinking about her sexually. But how to get her to let me was problem, then I ordered a bottle of whiskey online and after it was delivered. I notice that Thelma liked a tipple. Next time I ordered things online I got a whole case of whiskey. When it had arrived I put all except bottle away and left other out for to drink. Thelma seen it, but left alone for me to open. After dinner was finished and everything put away I opened the bottle and offered Thelma a drink. As before she drank it straight down and I filled her glass again. I wasn't drinking as much as her and made my glass last, while filling hers. Making her think I was matching her glass for glass. When the bottle was empty I got another one. By the time it was half gone Thelma was drunk. I put some music on and started dancing with her, feeling her up as we danced. She didn't try and stop me, after a couple of dances I was kissing her and she was kissing me back. I took her to my bed and we had sex. After a short nap I got up and went to the toilet and on my return she awoke and we fucked again. In the morning I fucked her when she was still asleep and then went showered. I was cooking breakfast when she came into the kitchen, she was hungover and asked me for black coffee. I gave her the coffee and ask how she was and said okay but a little sore, as it had been a few years since she had fucked and my cock was bigger than Grandpa Paul's had been. I replied I will take it easier next time and she said that will be good. I've been fucking her regularly since and we rarely drink now and have 9 bottles still left in the case. Thelma wants me to date women and find myself a wife. But she still gives me great sex.
