My first head experience

Im (18m) and she was (18f) Me and this girl have been talking for a about a week(there was sexting) and she was amazing, she checked all of my boxs. She was loyal, mature understanding, replys fast, calls me handsome, fine, complimented my body, every compliment you can think ok and etc. So i was comfortable with her and i told her if she wanted meet at a mall. She said yes and we did. When i tell you, she was a completely different person. She didn't know how to act, she was like a child than a women. She kept pooking me and doing weird things in front of people, i was so embarrassed to be walking with her. And I payed $30 on some food and bobba shit, and she wanted a toy for $50. I said no and Dragged her out of the store.She was a greedy one for sure. I wanted to leave. Until she said "do you want head?" Ofc i said yes even after all that, so we went to my car, and when she started, i felt her teeth on my thing. Shit was like some spikes go down and up on my thing bro It was bad. And when i finished, SHE STARTED SPITTING IT OUT ON MY SHIRT AND PANTS. IT WAS STAINED. What a waste of a first experience. I payed for everything ofc, but she paid for a lyft, never had i thought i would hate my first hawk tuah. I was so happy when I dipped out of there. My whole view of wanting to get head changed, never am i doing it with a girl that acts like this.
