One And Done

When I was 16 I thought I was gay. I was hugely attracted to one of my male teachers. I couldn't stop thinking and fantasizing about him. So I decided to test my theory.
There was a park nearby my parents had warned me about for the specific reason that it was a hook up spot for gay men. I didn't want a boy my age, I wanted a substitute for my teacher.
I went to the park one day and noticed a lot of men going in and out of a bathroom. I eventually went inside and it was true. There were probably 6 men inside the bathroom. I even watched a man perform oral sex on another. There was no problem getting attention. The older men were all hitting on me but none of them were hot like my teacher. I walked out and stood near the door checking out the men going in and out. Finally a very attractive man, maybe 35, walked toward the bathroom. As he walked up he spoke to me and I started a conversation to stop him before he went inside. It worked, he invited me to go back to his car. We got in and drove to a secluded spot. I made it very clear I was willing. We got in the backseat and undressed. I was so nervous I was shaking. He reached over, took my hand and placed it on his cock. I stroked him as we made out. His hands were all over me. After a few minutes he pulled my head down in his lap. I had never sucked a guy before but I took it in my mouth. He was big too, like 8 inches compared to my little 4 inches. As I sucked he played with my ass cheeks and fingered my asshole. He pulled me off of his cock and told me to lay face down. He poured lube in my ass crack and started working it in my asshole. Then he got on top of me and started working his cock inside me. All was great up to that point. It hurt like hell! He kept telling me to relax and he kept shoving his cock further into my ass. I was so relieved when he pulled back out, then he shoved back in hard. I screamed like a girl. After a couple of hard thrusts I felt his balls slapping against my ass. Tears were running down my face and I was clawing at the seat. I remember he was very verbal calling me a little slut and commenting on how tight I was. Thank goodness he didn't last long. He held his cock inside me as he came.
I decided right there I was not gay. I was never going to do that again.
