A new, darker religion

Lucy eagerly drank the angel's cum, wondering what the last gift would be. She licked the pussy in front of her, pushing her tongue as far in as she could. She only realized her tongue had gotten longer when she pulled back, the extra length becoming apparent. The organ split at the end, becoming forked.

Lucy looked at it, confused, until heat washed through her again, much more intense than the first time. Her body shook with convulsions as it raced through her body. Her feet and hands changed first, growing long black talons. Red bloomed on her fingers, rapidly stretching up her arms to cover her body. Her areolas darkened to black, her lips quickly following suit as they plumped up further. Her tits gained another size and her ass gained more volume, shaking with every step. The red hue covered her face and she gasped erotically, her mind remolding. Any thoughts of gentleness were replaced with a desire to dominate, to fuck and fuck some more, taking what she wanted from who she wanted. Her brown hair darkened, shifting to a lightless black. Black wings like that of a bat exploded from her back and a tail snaked its way down her leg, the phallic end drooling cum. Her eyes were last to change, red overtaking their green color as her pupils became slitted, her conversion into a demon complete.

"You are Lilith now," Grace said, coming down from another orgasm from watching the former Lucy's final changes. The renamed Lilith looked up at the fallen angel, their slutty minds aligned. They locked their lips together, their tongues tangling with each other as they reveled in their lust, Lilith's body a dark reflection of Grace's. Lilith broke off the kiss, her blood red eyes burning with lust.

"Time to grow my horde," she said, giving Grace's tits one last squeeze before turning and pouncing on a random cock, taking it deep in her slavering cunt. Her tail darted out, swiftly penetrating an open pussy. Both the man and the woman moaned in pleasure, the man's cock becoming dark red as Lilith started transforming him into an incubus. Similarly, a red hue spread from where her tail pierced the woman's vagina. All three felt their pleasure mounting as they came, the man spilling his now black cum in Lilith's clenching tunnel, her tail doing the same to the woman. They grew their own tails and wings, the man sprouting horns, and their eyes changing to the same blood red as Lilith's as their final transformations finished. All three immediately broke off, ready to make more demons.

"Excellent work," Aiden's voice said from behind Grace, making her jump. Aiden took the opportunity to stick his hard pole into her cunt from behind, making the fallen angel orgasm on the spot. She barely heard her master's words as her body exploded with pleasure. "You performed excellently. Plus, I like the idea. Lilith and her demons will spread quickly, transforming more into their kind. It think it'll be quite fun to watch," he said, watching the last non-demon in the room quickly transformed as she was double teamed by hulking incubi. He came hard at the sight of the woman's powerful orgasm, shooting his potent seed into Grace's pussy.

"Thank you, my Lord," Grace moaned, eyes rolled back in her head at the joy of being fucked by her god again. "I live to serve you."

"I know, slut, that's why I like you," he said, pulling out of her. She quickly grabbed at her pussy, catching any escaping cum and bringing it to her mouth, slurping it up. "Now, Lilith knows what she is to do. I think we should leave her to it and see what other fun we can have." They left the church, leaving the demonic orgy behind.
