I'm became my Grandma's Sex Toy

Several years ago grandpa Brian died leaving Lorraine 64 alone, I had a job at a company in the next town and it was closing down and moving all its business to the bigger town. Lorraine's town so I had to move and started to live with Lorraine, I'm Peter 26 oldest of Brian junior 3 children and only boy. My father is the oldest of 4 and lives in the city, he was happy that I was staying with Lorraine instead of her being alone. He had tried to get her to move to the city with him, but wouldn't move. Anyway I was fully moved at the time of the first lockdown and so I only had Lorraine for company. Nothing happen for the first week, but in the second week Lorraine caught masturbating and too k over masturbating me. The next day she asked me did I want her to get me off again and I had felt a bit awkward the first time. But just replied okay if you want I'm willing, so this time in her bedroom and she stripped completely naked like me. After she had gotten me off, she straight out asked me would I like to fuck instead of just hand jobs. I was a little shocked but I had let my gran masturbate me and I had felt her up as she done me. So I agreed, from then on I slept with Lorraine and she really like to drain my balls. Now I have a girlfriend Kerry 23 daughter of Lorraine's friend and neighbor Wendy 52 war widow, both Lorraine and Wendy are of similar build 5'7 or 8 and both drain my cock regular. Lorraine was always smiling and Wendy asked was she getting any and Lorraine said heaps. Wendy than asked was Lorraine willing to share and that's how I started fucking Wendy. Kerry is a quiet girl and only went out with me to please her mother and we hit it off. Kerry and I now sleep together and she is well aware of me fucking both Wendy and Lorraine and she had joined in foursomes. I've asked her to marry me and we marry in March, Kerry isn't taking precautions now as she wants to start a family as quickly as possible. I just got a pay raise and a promotion and things are looking up.
