Transcendence...

The screams of Melissa become piercing as your burning cum floods her now willing body. The hands that minutes before beat against your chest now grip your rear with slowly sharpening nails.

Melissa's hips buck wildly as she frantically tried to pull you deeper, trying to get more of your tainted seed inside her. But she is already filled to the point of overflow. But that doesn't stop her from lifting her body to yours, eager for more.

The previously innocent eyes of Melissa glare up at your own, hers already turning into catlike slits. Her transformation into a succubus was well on its way, but not yet complete.

While Melissa was slowly changing, you were nearly done. Your skin darkening to a deep red, while horns and bat-like wings sprouted from your once human body. Your cock expanding within Melissa's dripping wet folds, so much so that any human would be nearly torn in half. If she didn't go mad from the sheer pain first.

But Melissa was far from human at this point. The virus running rampant in her blood was already adapting her body to it's true purpose.

To be fucked and fucked some more.

Melissa looked up at you with wide eyes, almost as if she were gazing upon a god in the flesh. Her previous lust inflamed tenfold.

"Master please..." Melissa begged, all trace of humanity fading quickly. "I need more..."

"What do you need more of my pet?" Your voice had changed as well to a deep gravely tone, as befitting as incubus.

"I need more of your cock." Melissa babbled, words she'd not have thought of saying before flowing freely from her lips like the cum from her abused pussy. "I need more of your cum... violate me... fuck me... use me for your own pleasure..."

"Would you give me your soul?"

"YES! Take it!" Melissa screamed as your cock pulled from her body only to ram back into her brutally hard. "TAKE IT! MY SOUL IS YOURS!"

Melissa screeched in pure ecstasy as your resumed your rough fucking of the nearly succubus girl. Her demon-like nails now digging into your back and raking across your flesh. But this served to spur you on further, you could already feel Melissa's soul begging to be devoured.

Finally at long last, your reach your peak again resulting in a second load of cum exploding inside Melissa's **** womb.

"YES! JUST LIKE THAT!" Melissa screamed at the top of her lungs as she experienced the most explosive orgasm of her life. Your demonic sperm freely poured into her aching pussy, while her soul flowed into your body.

Melissa's entire form thrashed as she endured the final stages of the change. Her skin changed to a deep crimson to match your own while a pair of wings much like yours burst from her back. Horns freely growing from her head while a tail appeared beneath her.

All humanity now gone, Melissa flashed a fanged grin up at you. "It is done, my master."
