Well, I wasn't a baby, I was already 9-10 years old. She was over 30. I really don't know the weights, but I was skinny and she was tall and slightly thick and was a few times heavier than me. She always had skirt and bare legs and I liked to cuddle with the legs and put them on me. I used to put her foot beneath my shirt. She liked it but I was the seducing one. It was already quite heavy if she just put her whole leg on me full weight while lying on couch. But I got used to it and I could do it for a long time. Or sometimes I lied on the ground and she sat on couch with her feet on me. I promised not to tell anyone and I didn't. When she stood up to go somewhere she put more weight on me with her foot but not full weight and go away. She was slowly trying to find how much I can take. It was clear we both wanna try full weight. Then she went to the toilet and on the way she pulled up her skirt and showed me her thick butt. She knew I would love that. I took my shirt off and lied on the couch and waited for her. When she came she sat on me. I thought she is quite light, but that's because it wasn't fullweight. Then she sat with more weight. I thought I can still handle it, but she was adding more and more until I thought this is too much, but I didn't wanna stop her, so I just pretended I'm still okay. And she thought I'm okay, so she just sat full weight and then she even raised her legs and that's where I thought I will break. I couldn't breathe at all. She was like wow. Then she stood up and I breathed a lot, then she stood on the couch, put her feet on my belly and asked if she can stand. I was scared this will hurt me, but I was even more scared she would think I'm weak and wouldn't wanna do such stuff anymore, so I said "only a little" [of standing], whatever that means. So she stood quickly full weight with one foot on my belly!! It pressed my belly so much I thought she's standing directly on my spine. It hurt, I hoped she would put her other leg on me to have the weight 50:50, but no, she stood on my belly with one foot and then got off. She asked if I'm okay, I said I need a break. But I was damaged. She said we will do it next time again and I was like yeah we can. Then my parents came back and then we went to my grandparents for a few days and my belly was hurting, but it got better every day and I was thinking whether I wanna do it again. Next time I had to study for exams, so I was in my room and I didn't go to her, but she came to my room and pulled up her skirt asking whether I want this. So I went there and lied on the couch and she sat on me full weight. It was easier than last time and I did like a minute, then I said I need to study and she said okay and I went back. My belly and chest were crushed again. I thought that she thinks I need to study and we will try next time again, but she didn't wanna play next time, she probably thought it's to hard for me and that it's why I said I need to study. So we never did it again. My whole puberty I was fapping, imagining what would it be like if I became her sitting/trampling slave. What if she would jump on me with 2 feet? I think I would survive :) But we weren't meeting anymore and I was shy to ask this any other woman. I started paying BBWs to trample me when I was 25.
It was my fault that I didn't just tell her when I have too much. When she saw I don't tell when I have too much and I just make excuses, she can't know where my limits really are and she was scared of breaking them.
