Turned My Gf Into A Sub Slut

I have been dating my girlfriend for about two years now and I have completely turned her into my submissive cock-sucking anal pain slut.
When we met she seemed like your nice catholic school raised girl, but I have been slowly introducing her to all sorts of kinky sex and now my little slut does whatever I want when I want. Last night for example, had her legs spread tied to the bed footposts, bent over the mattress and hands tied and pulled to the other side where I tied them off. Next the blindfold and ball gag. There she is, tied, spread and all mine. I first pulled out the riding crop and spanked hey ass until it was glowing red, then used it on her spread open pussy. Next I lubed up one of our butt plus and shoved it nice and deep into her right little ass. I then used an assortment of toys on her pussy and clit while using the flogger on her ass. When she had already came 3-4 times, I shoved my hard cock up her pussy. As I am fucking her, I am whipping her back. She comes so hard when I do that. I pulled out just as she was cumming and she squirted all over the duvet and floor. I then pulled the plug out of her ass and replaced it with my cock. She came within minutes of my cock up her ass and then I shot my load up her ass.
I then untied her and she lay in my arms telling me she loves the way I fuck her. It took a while to get to this point, and I always introduced things slowly. If something made her uncomfortable I backed off and we tried something else. Last week introduced her to the crotch rope, now she wants it all the time. I had her legs cuffed and spread with a bar, crotch rope running back to front and then secured to the door frame so she had to stand a little on her tippy toes, toy in her pussy held there by the rope and hands tied above her head. Blindfolded and gagged again, I used every spanking toy I had on her; flogger, crop, and 2 paddles. It drove her crazy and she came like a freight train.
As I said, she was raised a good catholic girl and there have been a few instances where she used the “stop right now” signal and I would immediately untie her and cuddle her. She would have a little existential crisis as her two worlds collided but in the end, I won out and she tells me she is my personal whore to use however I want. Think I may have to use the crotch rope again, but not before I give her cute ass a good tongue fucking (she will cum with just my tongue fucking her ass). I am one lucky fucker.
Maybe when the weather gets nicer I will see if I can convince her to let me tie her up outside and fuck her at some remote place in a forested area.
