Consensual Non consent with a stranger on my birthday [FM]

I’ve been enjoying reading these stories for a while, but this is my first post. I don’t go into it in the story but for this encounter I vetted the guy and we had prearranged safe words etc.

Bit of backstory I (22 F) was in a long term relationship. My girlfriend had stopped wanting sex, and it turns out she’d been cheating on me. So we broke up and I was more than ready to get back out there.
I had a couple of boring tinder one night stands. They were pretty run of the mill but I was just happy to finally be fucked again. My birthday was coming up so I decided to try and indulge in a long held fantasy of mine. A birthday treat to myself.

I’ve always been very turned on by the Dom sub dynamic. I’m a true sub and nothing makes me wetter than being called a slut whilst being fucked. I love domination, humiliation, and being used. At this point I’d never experienced consensual non consent but I wanted to try it. I could have done it with someone I knew, but I felt like it would be most realistic with a complete stranger. I found a guy online who seemed like a good candidate. We texted for a few days and made a plan. My birthday party was on a saturday night. I was going to dinner with friends then hitting a few bars. The guy, Stephen, would come and pick me up whenever I said I was ready.
