Disgusting thot from high school and I turned our one-time hookup into a friendship with benefits

So, this chick goes to my high school and she's basically a total hoe. I mean, she's got the curves and she's not shy about showing them off, but she's also got this kind of gross vibe that just turns me off. But anyway, a while back, I ended up hooking up with her. It was a mistake, but whatever. Anyway, fast forward a bit and we run into each other again. She's still as slutty as ever, but now we've got this weird friendship thing going on. We're kinda friends, but we also fuck. It's a bit messed up, but it works for us. I know she's a total hoe and all, but there's just something about her that keeps me coming back. Maybe it's the challenge or the thrill of it all, I don't know. All I know is, every time we hook up, it's always wild and crazy. And even though I know it's not good for me, I can't seem to stay away.
