You gain the complete devotion of the Librarians

Minutes passed and you had already found a good rhythm. Felicity had gone from tentatively licking your pussy to having her nose on your ass as she ate you out. Meanwhile, Sara was aggressively fondling your right breasts as she suckled in your left one.

And then there was Julia. Julia's initial **** had completely went away. She moved her head along with your thrusts and her tongue eagerly lapped at the dark pre-cum coming out of your wet dick. Your juicy balls constantly slapped against her chin, but she didn't seem to mind in the slightest.

"Are you enjoying it?", you teased her telepathically. "Do you like sucking my cock, ****?". She didn't respond right away, opting to shift her position a bit to look at your face directly before answering, also telepathically

"Yes, mistress", she said subserviently, as she looked with the two deep globes of darkness that had taken the place of her pretty green eyes. She was yours. All of them were. You just needed to seal the deal.

"All of you, kneel", you ordered authoritatively. They all hurried along, and formed a line around you, greedily eyeing your throbbing member. You pulled your tail away from your manager's ass, to her disappointment, and pointed it towards them.

"Do you agree to serve me loyally for the rest of your lives?", you asked, fully certain of their answer. "Do you agree to a life of sex, lust and pleasure as my devoted slaves?"

"Yes, mistress!", they answered unanimously, unwavering in their allegiance to you. Just as you expected. Just as they deserved. "Then recieve my blessing!", you proclaimed triumphantly and gave one final stroke to your shaft before all hell broke loose.

A shower of your black seed covered their faces and bodies, which they eagerly began to drink with their already lengthening dark tongues. Their corruption proceeded rapidly, with their bodies molding to your idea of perfection. It wasn't long before the formerly modest Asian girl had to relieve herself of her shirt to free her growing breasts and soon the others followed. You could also notice their factions turning shapelier and more beautiful, as any extra fat disappeared from their bodies.

Their skin color too was shifting, sensitive to their personalities.

The vain Felicity had acquired a golden sheen that matched perfectly with her platinum blonde hair. Colleen, always the center of attention, changed into an alabaster white skin, rare among succubus, with a fiery red mane. The envious and submissive Sara, meanwhile, had received a light shade of green with little change to her usual black locks. And finally, the often wrathful and secretely lustful Julia, now had usually succubus bright red skin and a long dark mane.

All of them shared most of the other traits, however. Two horns, dark slitted eyes, a cock-tipped tail and an inhumanely perfect body built for sex. With one exception. Julia was mauling her breasts, gasping for air as one more change occured to her body. Sprouting upwards out of her long skirt was a throbbing, already leaking 8 inch cock. It seemed that she had some potential after all, if she has been granted the honor of becoming a sincubus, even if under your complete command.

Only a few seconds after you had finished your orgasm and the girls lapped at the last remains of your cum, a second one, even more powerful, wrecked your body. You felt like fire burning your insides, a hurricane of erotic magic converging inside of you as a conduit to yet undiscovered powers.

You moaned as your body transformed further, fueled by your new slaves corruption. You were getting taller, bustier and more toned all at the same time, and you loved every part of it. Your moans turned into an unholy laughter as you witnessed your cock extending and balls expanding. The golden slits in your eyes were shining bright with power and ambition.

By the end of your new corruption, you stood at 6'2'', with a new set of abs and muscles that didn't detract from your femenine curves and round breasts. But the star of the show was still your foot-long cock and the billiards-sized balls below them, ready to churn more inordinate amounts of cum already. As the cherry on top, your tail had split into two, with the cock-heads at the end thicker and harder than before.

Your servants stared in awe at you, already addicted to the taste of your cum and the feeling of your cock inside their bodies. You felt powerful, with an uncontrollable need to ravage these beauties and show them what the real Elizabeth was really like.

"Now, my slaves, shall we have some fun?"
