Unleash her full potential

"There's something inside you, Julia. Beneath all that rigid structure of yours there was a kinky sexual being waiting to be released. And I'm giving it a chance to come out. One last chance to show itself. To prove to me that you are truly deserving of that juicy cock you have been given". The woman sighed, relieved, as you chose the option most favorable to her.

But what you needed from her was not relief. But lust. Pure, unadulterated lust. You pulled strings in her mind, releasing her of all doubts, all self-constructed barriers, if only for this one moment, to allow the true Julia to come out. She would not be released from your service, not ever, but she could be allowed to display as much dominance and strength as she had it in her.

"Show it to me! Show me what you can do!", you stroked her cock, feeling its heat rising up with your touch. Her eyes went from submissive relief to the harsh, bossy glare that you had seen so many times before.

"Fuck me, Julia! Fuck me like the Sincubus you are!", your order penetrated the very core of her brain, finally unshackling her from all moral constraints. She had been broken and remade. She was no longer the old, boring divorcee. She was a demon of lust with one mission, and one mission only.

There was only a microsecond of surprise as she gathered some unknown strength and pushed you down to the floor, on your back, with her on top. A more insecure mistress might have felt worried about this sudden rush of power she was now displaying, specially coming from the woman that had once tormented her. But you were no longer that insecure little girl, and you felt complete confidence in the fact that could still get her firmly under your control as soon as you wanted.

Your breasts mashed against each other as she gave you a hard, forceful kiss, snaking her tongue into your mouth while holding your head tight. Both of your cocks were sandwiched in between, rubbing against each other, yet she didn't seem concerned in the slightest about her smaller size compared to yours, not even as your erection grew harder.

"I will not go easy on you, you insolent girl", the red sincubus said when she pulled out of your mouth, grabbing your cheeks. You knew it was only empty bravado, but you still managed to be impressed by her initiative "I'm almost sad I'm going to enjoy this just as much as you"

She stood up straight, on her knees, with her cock standing proudly upright in front of your pussy. "You might come to regret freeing me, slut!", she barked as her cock entered your pussy with a deep thrust that threw you off-balance at just how aggressive it had been. It was clear that, like you, the woman had a lot of pent-up emotions ready to come out.

She thrusted harder and harder, putting more strength as each one of her old frustrations and insecurities turned into potent sexual energy. "You three. Suck her cocks, now!", Julia ordered with such power in her voice that they almost agreed to her command right away. But they were still yours all the way, and wouldn't do anything without your approval. Still, you very much agreed with her request, so you mentally gave them permission to approach you and begin servicing both your cock and two tails.

"I never should have hired you in the first place. But now that I did, I will take pleasure in doing this!", she said as she entered your ass with her tail and began to fuck you from both sides. Yet she didn't stop there. "Suck harder, you little brat!", she commanded to Felicity, who was licking the top of your dick and she pushed her head all the way down to the bottom. At that moment, you decided to let go almost completely, embracing the pleasure that only getting fucked from all sides could bring you.

It was hard to say how much time had passed, an eternity it seemed, until you finally felt ready to cum. And you knew, so did Julia, still shackled to your orders to not orgasm until you said so. "Cum now!", she howled. "Cum now and let me truly become what I must be!"

Having seen the potential to your cause in her, you agreed, opening the floodgates for both your orgasms. She threw her head back as she pumped as much of her dark seed as she could into you, marking the first of many Sincubus' climaxes to come. You felt a rush of energy overcharging her mind and body, just as it had happened to you. She cackled as her body changed from her middle-aged frame to a tall and imposing figure, sexier than the hottest MILF on Earth. Her wrinkles were all but gone, but her face still displayed the wisdom of her age and the sterness of her factions went even tighter. You shuddered to think about how she could make anyone crumble under her harsh face even in her human form. And you made a mental note to have a good look at her curves once she outfitted herself with a tight librarian outfit.

But for now, your attention was focused on her cock, which had grown to 10 inches with balls almost as big as yours. In fact, almost everything in her body was only slightly reduced than your own, yet still much bigger than the others.

Her transformation was complete, and her eyes reflected the hunger that had been building up in her all this time. The hunger to corrupt, and to defile those already corrupted.

Yet even after all these changes, she still had one certainty above all. Everything she was, everything she had become, was owed to one person.

"Thank you, mistress", she bowed her head to you, in appreciation and compliance. "I hope you are satisfied with your new servant."

You chuckled. Oh, you were very satisfied. And you would be even more satisfied when you could see what she would be like when unleashed upon others. "I am, my ****. Because I have big, big plans for the both of us...". You eyed the three other succubus with the corner of your eyes. "Big, big plans."
