Hardcore anal penetration on young teens

I was once at a party with my friends and we were drinking and having a good time. I was dancing with a girl I had never met before and as the night progressed, I found myself getting more and more drunk. I knew I was getting pretty tipsy when I told her that she looked like a porn star and that she should be in porn. We continued to dance and drink but soon enough I was on the floor and she was on top of me. She started grinding her hips into my crotch which made me feel really uncomfortable, but I didn’t want to stop her from doing what she wanted to do. She then started to slip off of me and then started to slide down my body. As she slid down my body, she took my hand and put it on her ass. That’s when it happened; she slowly started to grind her ass into my fingers. It felt good, so I kept going until she removed her hand from mine and then slid back up my body.
