Dressing up as my friend's boyfriend's mistress for Halloween fun

I've always been a fan of dressing up and I was thrilled when my friend asked me to be her boyfriend's mistress for Halloween. I spent weeks preparing my costume, making sure every detail was perfect. When the day finally arrived, I was ready to put on a show. As soon as I walked into the room, I could see the excitement in my friend's boyfriend's eyes. He couldn't resist the sight of his new mistress in her sexy outfit. I gave him a deep, passionate kiss, making it clear who was in control. Then, I took him into my mouth, sucking his big black cock with all my might. He moaned with pleasure as I continued to suck him, my hands exploring his body. But he wanted more. He wanted to fuck me from behind, to take me hard and deep. And that's exactly what he did. He fucked me hard and fast, his big black cock sliding in and out of me. When he finally came, he covered my face with his hot, sticky cum. It was a night to remember.
