Good doggy

You lean forwards and let the priest's cock slip out of your pussy. He whines and struggles harder but you keep yourself, just out of his reach and continue teasing him. "Too bad you are still a weak mortal and can't break free. If you were a monster like me, you'd be able to tear yourself free and ravage my cunt..." You spread your cunt lips with your fingers and start to play with yourself. "Please... Let me CUM! I can't take it anymore, I'm so close!" "Tee hee hee... First you have to say 'make me your dog mistress' you got that?" "Make me- Make me your dog... mi- mistress." he stammers in his desperation. You lean back, this time using your tail to guide his cock in. He fucks you even harder than before in his desperation.

"That's it doggy! Bark for your mistress!" The former priest barks, but as he does so, his voice begins to change, becoming more and more bestial and low. His muscles bulge and he gains new strength. The metal bindings buckle and snap as your 'doggy' tears himself off from the cross and grabs onto your hips. You feel his nails grow into talons that dig into your skin and manage to draw blood as he can't control his strength. "YESSSS! Fuck me! Take me like the beast you are!" You are enjoying this more and more by the second. As you look back you see that his face is changing too, growing into a snout like a dog, sharp fangs replacing his human teeth as he transforms. You feel his orgasm as his dick pumps wave after wave of cum into your womb, making you also cum. Despite the climax, you manage to pull him into a kiss and suck in his soul. His body doesn't even react as the bright soul light is torn out from it and into your mouth. You see his eyes dim out for a moment, to be replaced with bright yellow glow moments later. Fur starts growing all over his body and when you feel his cock too grow to be almost as long as your arm and a canine knot squeeze your cunt to the limit, you cum again, harder than the last time. By this point, you lose control of the situation. The hellhound that is rutting into you, pushes you down against the floor and fucks itself into you without mercy or restraint. Just the way you like it. The hellhound lies on top of you and you can feel it's canine tongue lapping at your neck and face as it pounds you. Multiple orgasms leave you in a shivering mess and even a succubus like you feels like you are about to black out. Fighting back to stay concious you reach back and scratch the hellhound's head. The creature is the size of a bear and if you weren't a daemon, this massive cock would have split you in half. As it is, you can feel the bulge reach up to your chest, in this immortal (and immoral) body made for fucking and excessive sex acts.

Good doggy, indeed.

After your latest creation is finally exhausted and you push it off of you, you conjure up a collar for it. Fastening it around the neck and attaching a black metal chain to it. It does not resist and though this dark furred beast seems like an animal (apart from the evil glow in it's eyes and the two horns sticking out from it, you might be fooled into thinking that it was just a massive dog or wolf), it clearly is intelligent enough to know who it belongs to. You wonder if it can still talk.
