Story with my aunt

This is my first post, I wanted to take advantage of telling a small story that happened to me a long time ago, when I was quite younger and didn't understand much about romantic relationships or... More of that. Many times I would visit my aunt's house to play, I always liked to go and stay as long as I could, although one of them always looked at me weirdly, I didn't understand why but didn't give it much importance. One day, we were alone, my aunt and I, I was in the living room when she called me from one of the house's rooms (I can say that both the house and the place were quite spacious), without more I went to see what she needed, she asked me to help her with something, while asking if I didn't have a girlfriend or if someone liked me, to which I replied yes, she told me it was to be expected since I was a pretty attractive boy, she had fairly large breasts, good ass and was somewhat plump, brown hair, white skin and wasn't very tall, wore a shirt with a deep neckline and just seeing her made me get something hard, she told me if it didn't bother me, that I should rub against her ass, she was wearing lingerie that made her ass look even better, without thinking, I did what she asked of me, got on top of her and moved frotting my cock, already hard in her ass, felt like she was slowly getting wet, although by a noise from a truck, nothing else happened. Maybe I'll upload part 2 soon.
