I'd like to craft a control collar.
I'd start with an ordinary pretty collar, and then I'd start attaching triggers to it: you can't take it off on your own, when wearing it you must obey direct orders, and so on.
The cumulative effect would be for the collar to turn you into a subby, owned pet.
And of course, I could force you to wear it. I could hypnotize you and make you put it on, or I could just hold you down, strap it around your pretty neck, and watch all the defiance leave your eyes.
And sure, maybe I'd do that every so often.
But what if instead I just put it on the table next to you. You'd know exactly what it did. You'd know it would take your thoughts away, it would turn you into a horny toy... when you wear that collar, you aren't really a person anymore. I wouldn't force you to put it on. All I would do is tease you, flirt with you a bit. The collar is right there.
And soon enough, you'd be wearing the collar and kneeling expectantly, waiting for an order to serve. Because deep in your soul, you want to be owned.
