Oh, that's adorable. You're much further along than my boyfriend, which means breaking you is going to be so much easier. I know you think you have an upper limit to your depravity, but trust me, you'll do everything I say and you'll love it.
After all, you're already wandering around like an animal for me in a public park. If I wanted to, I could train you to always walk like that. That collar? That's going to be a permanent fixture before I'm done. I'd also say it's time for you to get a couple of piercings - nice big rings I can loop ropes through to control and torture you. We'll start with your nipples, and maybe, maybe if you're good, I'll let you out long enough to get your cockhead pierced.
And if you disobey? If you fight me? Well, let's just say it will be a long, long time before you ever see that key. I won't ask too much - not at first - but as you degrade yourself more it will be so much easier to take the next steps.
You can lean back on your knees. Hands on your head, elbows spread wide. Legs spread wide too, actually. Give me a nice view.
