Temporarily freed from your lust, you can't help but give a dog like growl at the sexy succubus. This wasn't right. You had just escaped from a psycho just to become a sex slave?
"Awww, is my poor puppy angry? You won't be for so long, soon you'll be my submissive little sex slave."
As she said that you could feel her magic working on you. Trying to change your very personality and body. Trying to make you into her needy servant who can't do anything but wait for his "mistress" to give him a treat. But no. You wouldn't play with her games. If she wanted a dog. You'll give her a dog that will DOMINATE her instead!
You push back the magic, resisting its effects. You try and stand but find your finely toned muscles surprisingly weak and numb.
The succubus laughed.
"I can feel you trying to resist, give in little puppy. You can't do anything. I have spent centuries collecting my army of hell hounds and soon I will finally become the Archdemon Of Lust! All I need is enough followers to lend me their divine faith so I can grown even stronger."
Still resisting you say "I won't let you." You grit your teeth trying to resist the magic with all of your will.
"I admire your courage but you can't stop me. Give in you horny beast, soon you'll be nothing but a wild mutt just waiting to drink from my nectar." The succubus said, with that she started to finger herself, taunting you by spreading her pussy.
But what she didn't know was that you HATED being called a mutt. You felt strangely insulted by that word. You grit your teeth harder using all your might and pushing through the magic and pain you manage to finally stand up after what seemed eternities. You stood up naked, the weakness in your muscles only seeming to be growing as you started moving towards her.
The succubus for a second looked worried, but then it passed, a devilish smile crossed her face and with a finger she said in a commanding voice "Sit down you bitch."
The weakness suddenly multiplied and you nearly staggered to the floor. But you managed to stand back up.
"No, NO. You won't be taking control of me. I'm no mutt, I'm a wolf and I'm going to show whose the real master here!" You say.
You lunge to to succubus not giving her a chance to react as you plunge your hard cock into her wet cunt. You start rutting her folds, wildly thrusting in and out. You grab her arms and force them apart, making her scream.
"No, this WASN'T supposed to happen! No stop this at once!" She screams between moans. She tried resisting but found herself trapped between the couch and you.
The weakness suddenly started disappeared and you start moving faster and faster loving the intense pleasure and the feeling of domination. You keep plunging your thick tool into her enjoying her moans. By now the succubus had stopped screaming and was now just moaning in pleasure. She buckled her hips against yours like the bitch she was as you have no mercy.
Your body started changing as well, each time you thruster you thick cock between her legs, dense black fur started growing on your body. It began covering everything your face, your body, your legs as it spread. Your face developed a muzzle, your nose turning black and your teeth fell out of your mouth, being replaced with sharp long canines. You ears became pointed and wolf like and were relocated to the top of your head.
Unlike before you welcomed these changes, loving every second of your transformation as your new bitch couldn't help but moan at your dick.
Your hands and feet now coated in fur as well grew pads and sharp claws capable of cutting diamond grew on them.
Soon you gave a moan of pleasure as your penis began to change as well, it quickly became canine as you thruster in and out of her pussy, gaining a knot and a sheath as your pink penis turned red. Your legs became digit grade and to top off the transformation, you felt a pressure above your butt as a thick fluffy tail grew. Now you were a sexy demonic hellhoud ravaging this succubus who had dared to call you her mistresss.
You quickly tired of your position as you both go doggy style, with you onto as you bite down on her shoulder nearly drawing blood.
"Now, tell me? Whose the real bitch?" You growl at the succubus.
"Oh, oh master I was so wrong, please master I'm the bitch! I'm nothing but your horny sex slave! Please master! Fill me!" she screams.
Not one to disappoint you starting taking full advantage of your new demonic stamina, filling precum start to build but as you come closer to orgasem. You make your succubus moan louder as you keep thrusting, enjoying every second of it.
Finally you feel a rush as her orgasm finally arrives lubricating your dick further. You however keep thrusting making sure not to orgasm for a while in order to show who was dominant.
"Now, tell me what do you want me to do bitch?" You ask thrusting harder and harder.
"Pleaseee master! Fill me with your essence!"
Then in a mindblowing orgasm you finally fulfill her wishes as you start unleashing rope after rope of cum, your knot inflating and making her scream as you cum in her for nearly thirty minutes. Then a strange feeling comes over you as you literally begin to drain all of the succubus's magical power and knowledge into yourself, officially claiming her as yours.
Exhausted the succubus faints, unconsciously fingering herself. After your knot shrinks you examine your new body. You loved it. You were strong, fast, and powerful. What's not to love?
Then you realized that despite already cumming your dick was still rock hard. You were about to masturbate by yourself when you realized you had this unconscious sex slave her, ready to be fucked even if sleeping. You grin as you begin thrusting in her again.
