All In

"Are you ready to meet Mistress Lilith and ascend?" you ask.

"Are we ever," Amanda replies eagerly as she stands from the bed."

"Come on Meg's," she encourages her kid sister. "We've been trying to stay human too long already. I'm done with fighting, I just wanna fuck with you for eternity."

"Oh, yeah," Megan agrees, rising next to Amanda "I can't wait to see you all slutted up like Kristen and Maya, you sexy bitch."

You step behind Megan and pull Amanda close to you both. The sister rub their naked bodies against each other as your long cock parts Megan's legs. She straddles and guides the tip into Amanda's dripping snatch. You enjoy the look of Amanda's eyes growing wide as you push into her cunt. Meanwhile, you move your tail between the sluts and begin to fuck Megan as well.

Maya and Kristen approach and take a position on either side of you.

"Is this a private party?" Kristen asks.

"I'm sure we can find a spot for you two," Megan responds.

"Oh, I know right where I want to be," Maya says. "Right here."

Amanda lets out a pleasurable grunt as Maya's tail invades her ass.

"Where I can get a taste of my dear friend's delicious soul."

"Oh, yes, yes," Amanda moans. "I can't wait to give it to you. Fuck me, fuck away my fucking soul."

"And I'm gonna love taking yours, you little slut," Kristin says as she plunges her tail into Megan's ass."

"Yeah," Megan shouts. "I'm a slut, fuck me, make me a sexy, succubus slut like you."

Maya kisses Megan as Kristin matches her move with Amanda.

The succubi lift Amanda, allowing you to pound her harder as you enfold the quartet of beauties, a pair of demonesses and a pair of demonesses to be within your wings, creating a list filled cocoon of pleasure.

Maya breaks her kiss with Amanda and raises her hefty tit toward her friend's soft lips.

"Drink and be reborn," the dark priestes offers.

Amanda latches on to Maya's breast and drinks hungrily. Megan reaches for Kristen's breast and begins nursing as well.

Reaching downward, you grasp each succubus by the ass, plunging your thumbs into their puckered assholes and your middle finger into each pussy. Meanwhile, your index finger massages their taints.

All this attention is too much for the sluts to bear, and each of them explode in thunderous orgasms throbbing around your fingers and pumping cum from their tails.

This triggers the final human orgasms from Amanda and Megan. Their pussys warm as you feel their souls flow into your cock and tail. Maya and Kristen's eyes flutter as they join you in consuming their first souls.

The sensation is far and away better than simply fucking. While neither Megan nor Amanda was particularly pious, both of them were good, caring young women. You utterly destroy that part of them, devouring anything other than evil and lust. Their souls are like a fine wine, a hearty base of goodness with accents of petty sins like vanity and selfishness that offer unique accents as you siphon off their mortality, leaving each as a vessel for Lilith to fill with evil.

You roar with power, pounding the soon to be hell whores even harder.

Megan screams as your tail moves deep inside of her.

"Oh, fuck me, fuck me hard you fucking stud,"

Amanda chides her sister, "Such naughty language. Do you kiss your mother with that mouth?"

"Ohhhh," Megan responds, "Kiss mom. FUCK MOM."

"Yeah"Amanda agrees, "we've gotta find mom when we're done and share this with her."

"Oh, oh yeah,"Megan shouts, "as long as daddy didn't get to her first."

"Uhh huh," Amanda replies, "did you see how big his dick is? I can't wait to slide it into my slick cunt."

Amanda pulls Megan into a deep kiss. You notice a change as you slide into the her once again Her lips pull tight around you and the walls of her pussy articulates around your cock.

Amanda pulls herself from the kiss and smiles at you with pride at her new ability. As her long, black tongue retreats into her mouth, you note that the tip is sporting an obvious fork. Amanda's lips swell before your eyes, darkening into black, cock sucking pillows that contrast sharply with gleaning white teeth highlighted by evil fangs. She bats her eyes at you as you admire the subtle charges to her face. Thinner eyebrows, darkening lids, and higher cheekbones refine Amanda's features to those of an alluring high class whore. The whites of her eyes darken until they are black as coal. The blue of her irises quickly turn to a deep crimson as her pupils thin to black, pointed demonic slits. Witnessing this utter corruption your spirited, former ally in the fight against the demon spawn is too much for you to contain. Seeing Amanda descend to join you as a creature of Hell causes you to erupt within both her and her sister.

You pull out, extending your wings to release the bevy of beauties. Megan turns, taking in your powerful pose while you admire her progress from the barely legal teen you met just a few hours ago into the immortal succubus that she soon will be. Like Amanda, her face gained an unearthly beauty maturing to appear like a twenty-something, a twin to her sister. Her nubile body is gaining luscious curves with widening hips and heavy breasts. Her nipples stand firm like bullets on her still growing chest. She cups her tits, appreciating their increasing mass. Her right hand slides along her taut stomach, reaching her pussy, Megan begins to finger herself. You note that Amanda is doing the same. Both sisters stroke blackened pussy lips, teasing their engorged clits that poke from mounds that are smooth and hairless, ready for devouring the treasures beneath. You note with pride your black cum that glistens on their pussy lips as it slowly drips down their thighs.

"This is awesome," Megan whispers in a throaty voice.

"Oh, yeah," Amanda agrees. Her voice has changed as well. Both are stronger, deeper, and exude promises of lust. "I'm so fucking horny. My clitty is so, so sensitive. Your cum feels so hot inside me. Just need to, need to cum."

"OHHH," Megan agrees, "need to fucking cum."

"We can help you with that," Kristen says, stepping to Megan as Maya reaches for Amanda.

"Yea, Mandy," Maya offers, let me eat that cum out of your pussy and ass. I'm sure I can get you off.

"Ummm hum," Kristen says leading Megan toward the bed. "and when you cum you'll be complete. Sexy, sinful succubi, just like us."

Kristen lays on the bed, and Megan jumps on her face. Maya does the same and Amanda settles onto her waiting tongue. The sisters embrace, hands exploring bodies that grow firmer by the moment. Maya and Kristen fuck themselves with their tails as Amanda and Megan rock their hips back and forth across their faces. Their asses swell into heart shaped bubble butts.

Amanda and Kristen mash their bodies together. Their tits grow further and further, reaching inhuman proportions. Megan's breasts grow to where the swell of her tits can be seen from behind. Delicious black milk pools on the ripe nipple of Amanda's equally impressive breast.

"Drink, sister," she encourages.

Megan eagerly lowers her lips to Amanda's tit. Swiping it beneath her long tongue, Amanda shudders as Megan loops her lengthened tongue around the swollen nipple and begins to suck.

Amanda turns her head back and forth in pleasure, her hair has grown thick, lengthening as its long curls flow across her back. Tossing it over her shoulders, you can see the tips of Amanda's now pointed ears peek though her jet black tresses.

Megan's raven mane is now a match for her sisters, and Amanda stokes the locks from Megan's forehead with her delicate fingers that are now capped with deadly, black, razor sharp claws. She wraps her hands around Megan's burgeoning horns drawing her upward into another luscious kiss.

Humping against each other, you notice Megan's tail extend from above her ass. She sweeps it from side to side, then with a giggle, she pushes Amanda from her lips and drives her new appendage into Amanda's waiting pussy.

"Oh, fuck yeah, Megs!" Amanda screams between her fangs. Looking over her shoulder, Amanda sees her own tail has appeared. Quickly putting it to good use, Amanda begins fucking Megan as well. Rocking back and forth, stroking the tail plunging into them. You can see the tails begin to throb, depositing their first loads of cum into quivering a quivering pussy as each new succubus cums at last. Their skin goes from it ordinary human tone to an exquisite, deep red in a matter of moments. Each of the evil twins grimaces as the skin of their backs parts and their leathery black wings shoot out like switchblades.

Completed at last, the succubi sisters climb off Maya and Kristen who rise to embrace their former friends and now fuckmates. You admire the quartet of demonesses you've created eager to see where your service to Lilith will take you.
