Slut Craves Humiliation

Have a cute little super submissive toy who simply craves having her limits pushed.
She enjoys regression type stuff and being controlled and unable to stop what's happening to her nubile body.
So one of the latest things I came up with was to have her bound with cotton rope and forced to lie on her back with her legs spread and pulled up. That exposes her tender little asshole, all smooth and begging for attention.
I'll lick and deep rim her hole and then gently insert one finger, then two fingers, then an enema bulb and hose. I give her a saline water mix and use enough to make it a little uncomfortable.
Then I put a diaper on her.
After teasing her and degrading her a bit she was even more excited than I expected and forcing her to empty her bottom out into the diaper and to feel the warmth all under her butt.
After awhile I'll give her a good change and let her suck my dick instead of her pacifier until I empty my balls down her throat.
