Becky falls once more, completely corrupted

"You know this power. Now that you know it, you won't be able to resist it..."

She put an hand on the book. It was warm, radiating energy from its dark core; her pussy had become wet once more, ready to be rocked by another orgasm. Mark's eyes were lit by an hellish red light, like if his very soul was burning. It looked like he so desperately wanted Becky to use the book, to embrace its darkest powers.

"You've promised me happiness more than once, but it only made my life worse each time I accepted. "

"It wasn't me to ruin your life, Bex. I gave you this body. You are the one choosing to feel remorse. There's nothing wrong in using one's power. "

Becky's heartbeat accelerated, as she begun to furiously tremble. A stream of energy begun irradiating from the book, making her hand feel warm.

"I... "

"You want it right? I'll destroy your remorse. I'll bend your soul to fit your desires. You will be in control."

-... I WANT IT! NOW! -

She begun to scream, as the forces of hell irrupted into her body. A stream of darkness came out of the book, irrorating each cell of her body. Inside her mind she was screaming in pain, as every thought was overwhelmed by the power of the dark ****. She looked down at her hand, where purple spots had begun appearing, quickly enlarging until her hand had become of an hellish violet. Her black nails had now transformed into a pair of sharp claws, shiny with red reflections. The purple spots begun spreading to her arms, making her skin feel like it was burning as they expanded.

-Oh my God...-

Her whole arm had become of an hellish violet now, and strange tattoos appeared magically on her skin. She looked down at the images appearing on her body, trying to recognise picture of snakes and other strange animals which now covered her whole arm and were expanding to the rest of her body. It was clear she was no longer human, and damn it felt good.

Soon her boobs too had become violet, but the transformation wasn't over yet. A dark portal appeared from the book's pages, and soon a dark liquid substance emerged from it.

"What is it? "

"You'll see it soon"

The black goo jumped on Becky's boobs, spreading over them. It soon formed some sort of a leather bra, tight on her hard rock nipples which shape could be clearly seen emerging from the bra. The bra magically held her boobs in the air, leaving her shoulders and back free, and it only barely covered her boobs, letting anyone see her glorious fool moons.

-More! Give me more!-

Her face too know had become of the same hellish violet of the rest of her body; as the corruption spread her beautiful blonde hair had become as white as snow. But the biggest change was happening deep inside her soul; her humanity was burning, replaced by a list wilder and stronger than anything she had ever felt. She begun to laugh maniacally, as a pair of horns erupted from her head and further changes occured across her whole body. Her eyelids soon turned black, as her lips became even fuller and darker; her canine teeths lengthened, transformed into a pair of fangs. Her pussy had become wet, and she felt the **** need to fuck someone. The pure lust was overwhelming her, and she jumped like a wild tiger on top of Mark.

-Fuck me ****! Fuck your mistress!-

As usually Mark obeyed, his erection ready to be put at use. However Becky's transformation wasn't over yet , as her hips became larger with every thrust of Mark's cock. Her legs had become purple too now, and a pair of black leathery wings had erupted from her back, opening and spreading across the room. The dark seeds planted inside her had finally bloomed into a flower and fuck, what beautiful flower she was. Mark came inside her, filling her one last time before collapsing in the floor. More pieces of dark matter came out from the portal and fell on Becky's body; they formed a pair black of black briefs that did no effort in covering her gorgeous ass. She liked her new self, after all.
