Yes

Alex growled as he lay his taloned hands on Carla's shoulders and brought his face in line with hers. In desperation, Carla tried to escape from the Incubi's grip but found it impossible to do so. A booming laugh tumbled from Alex's fang-tipped maw as he parted them to snarl; "Oh no Carla, you have to understand, your demonic rebirth is a gift."

Carla trembled in fear as she looked up into her former beau's slit serpentine eyes, they contained no compassion or warmth. A chill ran down her spine as she heard the crunch of gravel behind her, moments later she felt Olivia's fiery flesh push against her back. The Succubi slut giggled momentarily before mewling "Alex, the only way she'll understand is if we give it to her."

Olivia took a step away from her prey before effortlessly relieving Carla of her clothes with her taloned hands. Carla moaned involuntarily as she felt the warm sun beat down on her bare flesh. Both demons snarled in anticipation as they sandwiched Carla between their statuesque crimson forms.

Carla groaned as she felt the tip of Alex's mammoth cock tentatively tap at her bare pussy lips as his taloned hands move from her shoulders down to her waist. Olivia begins to softly kiss the nape of Carla's neck and draw a melody of sweet moans from her pale lips. Alex drops her a sister fang-tipped smile as he savagely thrusts his cock forward.

A series of gut-wrenching screams erupt from Carla's lips as Alex relentlessly spears his mammoth cock in and out of her slick cunt. Olivia giggles maniacally as she roughly grips her preys breasts for leverage before ramming her cock-tipped tail up Carla's virgin taint. Another scream slips from her lips as she is savagely taken from both ends.

Olivia groans in delight as she feels the tip of Alex's mighty shaft touch the tip of her slender tail-cock. Blood oozes from Carla's flesh as it coats her body with a crimson sheen, copious groans slide from the couple's lips as they ravage their former companion. Carla no longer screams out of fear but lust as she feels both demons erupt within her.

Carla's former baby blues snap open to reveal two newly slit irises swimming in pools of hellfire. The blood that flowed freely from her wounds has shifted into a tarry black as it starts to stem. Olivia purrs in excitement on feeling Carla's B Cups swell into DD's between her taloned fingers. Wanting to get a rise out of the slut she pinched a turgid black nipple and watched as a stream of tainted black cream splattered onto Alex's herculean chest.

Alex watched as Carla parted her darkening lips to flash him a fang tipped smile whilst she butted back against Olivia's cock-tipped tail. A low groan of blissful ecstasy tumbled from Olivia's lips as she felt Carla's rear clamp down on her cock-tipped tail like a vice. The proud Succubus roughly slapped the transitioning harlot's pert crimson cheeks, eliciting another animalistic grunt from her fevered maw.

Carla couldn't believe the carnal pleasure she had actively denied herself as she rode a small orgasm whilst a newly cock-tippled tail eased out from above her cheeks. Wasting no time she rammed it between Olivia's dripping folds. The Succubus didn't complain as she yanked on Carla's luscious blonde locks as streaks of onyx appeared within them.

Alex grinned as his slit eyes darted down in time to witness Carla's pale flesh take on its signature crimson hue as two leathery bat-like wings erupted from her back. Tar-like cum oozed from Carla's tainted cunt as two ram-like horns pushed from her forehead. With her transformation complete both Alex and Olivia eased themselves away from their new sister.

Carla fell to the floor with feline grace a manic smile on her pitch lips as she lapped the droplets of stay cum from her chest. As she lay on the floor Carla felt another tremor of orgasmic pain run through her body. She groaned as she felt a warm sensation intensify within her loins casting her eyes downward, Carla noticed the flesh above her cunt begin to pulsate.

A chorus of grunts slid from her lips as a fleshy mass pushed out from her flesh. The others circled around her as they watched the new appendage ease from her body. A few moments later it stopped at a staggering twelve inches, slowly a pitch mushroom-like cockhead formed, cum oozed from the newly acquired slit. Before a crimson sack followed out the twitching member and slapped against Carla's bare cunt.

Clara felt honoured that The Lilith Strain had granted her the sinful pleasures of both sexes. As the first Sincubus, Carla knew she would have fun converting more innocents into her Sincubi sisters.

Alex and Olivia were overwhelmingly satisfied with Carla's corruption. The newly transitioned slut eased herself up onto her taloned feet as her slit serpentine eyes darted between them and she parted her glistening fangs to hiss "Mmm, I can see what you meant sister, that was one hell of a ride."

Olivia chuckled momentarily before Alex shot her down with an authoritative look. Carla groaned as she felt Olivia's lips curl around her newly formed cockhead as they waited for Alex to speak. After a few playful minutes, he opened his fang-tipped maw to begin; "So tell me sluts, wheres the best place to hunt for our next victims?"
