Humiliating My BF

I humiliated my bf by having sex with some random hoodlums on the street in front of him. The street bums were just chilling near the sidewalk. They looked like gangsters and most were black.
This was when we were walking back from a house party together in the middle of the night. He called me a whore for wearing revealing clothes and humiliated me in front of my friends. When I protested that it's just how I dress, he slapped me and said that I probably screw random men behind his back.
I'd had enough of his nagging and complaining and I was really hurt when he hit me. So, I walked up to the dudes and asked who wanted a "good time" in a sexy voice. They asked me my price and I said that I just needed a cock and my bf's cock is tiny so I'd let them do me for free.
They didn't believe me, and it was fine because I wasn't really gonna do it. I just wanted to humiliate him but he kept pushing me, saying I can't do it and I don't have the guts.
I just got fed up so I dropped my dress in front of them. I was wearing nothing underneath. I turned to look at bf and he had the expression that I wanted to see. Shock. One of the guys walked toward me and grabbed me and I wrapped my arms around his neck and kissed him.
That's when I heard my bf yell, "HEY!" as he started toward us but another guy stepped in between and stopped him. He couldn't do anything.
I ignored him as the guy pinned me against the wall and started touching me. I kept kissing him while occasionally glancing at bf. He clearly didn't expect this.
When the guy started to shove it in me, I was already wet and I enjoyed it more than I thought I would. He made me cum hard and I let him cum inside me. My bf walked away, defeated and I stayed, while the remaining guys took turns doing me hard. They all came inside me.
When I reached home, covered in sweat and cum dripping from my puss, I immediately went to the shower. I wept after realizing what a stupid thing I did. But I had my revenge 'cause he had also cheated on me before.
