Rae converts Lola

Rae's eyes shot open.

Immediately, something shot out of her pussy and wriggled around, still lodged inside her. Waves of pleasure hit her, and she moaned indulgently as she felt her new appendage rub against her sheets and blanket.

She remembered her dream, though she knew it wasn't a dream. Or at least, the last part hadn't been. She grinned as the fear washed over her, it's power so overwhelming that it spilled right over again into joy. She needed to spread this, needed to flex her power. She needed to dominate. Then, Lola grunted.

Rae's head whipped toward her twin sister, asleep in her own bed. Such a pretty thing, so innocent. Or was she? Her plodding, meticulous manner... her careful consideration of every move, every word... no, Rae could see now. That wasn't innocence. That was a coping mechanism. It was a veneer.

It was fear.

Lust swelled inside Rae, the desire to corrupt, to spread. She would have her fear. She would use it. Rae flung off her covers, quickly removing what little clothing she had on as she closed the gap between her and her prey. Her worm squealed with joy as it was carried to its target, and Lola didn't move or wake up before Rae violently wrenched open her sister's sleeping mouth and jammed her Master down her twin's throat.

Lola immediately began to thrash about. She tried to dislodge the thing from her throat, but every movement just sent ecstasy through Rae, causing her to tighten her grip. She looked down at her sister. Lola was looking up at her with frantic eyes, fear written all over her face. Rae giggled. The power was intoxicating. She was in control here. Lola's fear was hers now. It felt so good.

The pleasure built up quickly, and then Rae came, throwing her head back with a guttural moan as her worm Master surged in her cunt. All of a sudden she felt it release, shooting something into her sister. In moments, Lola had stopped thrashing, writhing slowly underneath Rae, as if she'd been ****. Rae eased the pressure, but found that, instead of struggling, Lola was now actively felating the monster in her throat. Rae felt a lecherous thrill as she continued to **** her twin sister's mouth, the infernal goo from her new master causing Lola to break and give in to the pleasure. The excitement of corrupting her sibling sent her head spinning, her broken mind relishing the abhorrent evil she was participating in.

"Fuck her now. Let me spread your gift to her."

Rae reluctantly pulled herself out of her sister's mouth, obeying her Master by flipping her over. Lola's perfect round, thick ass nearly sent the new Rae into a frenzy. Without hesitation, she plunged her Master into her twin, Lola's pleasured grunts music to her demon ears.

"Fuck her. Use her. Give in to this, and I will be able to make her like you."

"Yes Master, yes!" Rae screamed.

Rae drove into her sister's cunt with renewed vigor, bathing in the sensation of her sister's perfect ass bouncing on her as she fucked her from behind. Without warning, her worm tentacle pulled itself out of Lola, and then immediately struck, latching itself to her clit. Lola cried out in horrified pain, as Rae felt the euphoric sensation of something pumping through her Master and into her sister's clit. Then, her Master detached itself, and slithered back inside her.

"Watch."

Rae didn't question. She watched as her sister moaned and wriggled, the pain in her voice turning to pleasure, until she was crying out in bliss. Rae watched with demonic glee as her sister's clit swelled, elongating slowly, and eventually taking on a phallic shape. Her slit closed up, and what appeared to be two testicles began to grow where her labia used to be. As the transformation seemed to be dying down, her Master shot out once more, latching itself first on to one testicle, then the other, seeming to pump something into each one. Rae felt oddly empty now, but Lola began to cry out once again, her new balls swelling until they resembled oranges.

Soon, Lola's cries died down into whimpers, then into pants, then into grunts. She began rutting the air, and the moment she touched her new clit-cock, she howled. She began to jerk herself furiously, and Rae watched in glee as her sister became a nightmare before her eyes.

Lola came, spewing jet black cum everywhere, and roared the guttural yet feminine roar of a demoness of lust.
