I was at an amusement park like 8-9 years ago and it was dark and a small concert was going on. Some Jamaican girl started shaking her ass and for some reason she started to rub her ass with my ass and the back of my thighs. It was a grind but on my ass and the back of my thighs. I didn't know what was going on. It was very strange but it felt like she had a big booty so I allowed it. I just stood there while her ass was rubbing on me while I was watching the concert by some local but famous artist. I tried to not even acknowledge that she was doing it. I was wondering what she got out of doing this. I was in a daze. The place was so damn packed too which made the situation more awkward. I was a shy little virgin kid and she was at least 5 years older than me. She must of thought I was her age due to my older looking appearance. She kept doing this strange technique for maybe 2-3 minutes until she stopped and walked away. I turned around and she looked annoyed and walked into the darkness.
The strangest day of my life. It was clear to me now years later she wanted me to turn around and dry hump her by "grinding".
Well, she should have instructed me how this thing works. I was only 13 or something. She failed to seduce me but tried nonetheless
