Naturally

A new kind of demon for a new world, you muse as you caress the other demoness's cheek and consider her tantalizing offer. Curling your mechanized claw, the space between the joints glows with hellfire, grazing her supple scarlet skin and causes her to bite her lower lip and shiver with desire. Fulfill the Succubus Queen's agenda. The voice is no longer an emotionless drone but a sultry and purring feminine drawl. Like you needed any encouragement, you size your sister in sin and press your pouty and perfect silicone lips against their fleshy twins in a deep and noisy kiss. Your tails entwine, yours thicker and segmented with hers thin but flexible, before their spaded tips enter your dripping and eager pussies

The whorish and slick noises the pair of you make join with that of the other Succubus and the brunette captive. Sparing them a glance, you see the human has lost any resistance and is now eagerly begging her captor to make her cum her soul out. The edges of your lips curve for a second, imagining that you had worn a similarly desperate expression only a few moments ago, before returning your attention to the demoness and her lashing and delightfully sinful tongue. A muffled moan escaped from deep within your throat – they hadn't spent their time locked away here idle. Your memory banks, already uploaded with pleasure routines courtesy of the conversion tube, added the recordings of her techniques to its library for later... hmm, study.

The demoness's face began to sink toward your crotch as she bends her knees, spreading her legs wide. She left a trail of burning sensations that made your mind reel with bliss from the garbled bursts of information coming from your densely packed sensory modules. Her hands lingered, playfully teasing with your enhanced breasts that spilled out between her grasping claws. Their insistence made your back arch with pleasure, and the hellsteel wings unfurl in their full glory. The digital weave between the wing's digits shimmered with scintillating neon colors even in the darkness of the Succubi's dungeon, the circuits danced with coursing electricity.

Your hands clasped her head as the twin forks of her tongue teased your protruding clit sitting above your synthetic sex. A defensive mechanism activated, dispersing the intense pleasure throughout to compensate it felt as if almost your entire body was bathing in her saliva rather than just your clit. So much still left to learn about your pair of upgrades and how they interacted with each other, you thought as it settled. You had eternity ahead, but right now your entire focus was the tongue and tail pistoning inside your core. The black fluids gushing from your slit stained the demoness face. Your muscles convulsed around them. With barely a thought, you could take manual control over them and other functions to make it an unforgettable experience. However deciding against it, no matter how satisfying it would be to artificially extend this.

Freed from her bonds, the demonized brunette, now a stark white, and her corrupter join your tryst. Unlike the other two, her skin is powder indigo instead of red, but her inky black orbs, tail, horns, and wings leave no doubt about her allegiance to the Succubi Queen. She pries apart your ass cheeks, her supernaturally extended tongue teasing the other rim of your anus before entering. The organ's original function erased and replaced as simply another vessel of the ecstasy washing over you. While the red-skinned demoness locks her lips around one of your nipples, drinking deeply of your corrupted milk.

Those not blindfolded stares at the sapphic display as your bodies writhe, mouths moaning, in unison. Their transfixed eyes are hazy with lust, the shafts of the men throbbing, while the woman grinds their glistening thighs together. Jenny's breathing is labored and heavy, still affected by the ambient noises, corruption, and pheromones, you can sense she's on the verge of cumming. Just. A. Little. Bit. More...

You cry out together with her. Yours is a sonorous screech tinged with the metal of your new form that sent those still resisting over the edge. A jet of cum lands one of the hell-forged plates covering your body the liquid immediately started to hiss and evaporate as you drain the globule of its life essence. The taste was indescribable as you and your sisters fed on the ambient energy of the sexual release, bodies wracked with pleasure.

Your new sister embraces you from behind, a hand snaking across your waist. She brushes away smoldering onyx metal tendrils and kisses the exposed nape of your neck. "Thank you for trying to save me earlier. It was a touching gesture." Her voice is ethereal, washing over you like a silken caress coming from everywhere and nowhere at once. Lilith couldn't waste this chance with inferior servants. "Came so hard when I saw your hypocrisy and you surrendered to your desires, made me realize what I truly wanted. But you didn't come here for me, did you?"

Your burning gaze settles on Jenny. Fulfill the Succubus Queen's agenda. Convert the slut into a chromed hellion. Make her a perfect little harlot. She seemed to sense your eyes roaming across her shapely body that you had once envied and been intimidated by in equal measures but now only see its potential, as she turns her blindfolded gaze directly toward you. An involuntary shiver, perhaps out of fear or the aftershocks of pleasure run through Jenny's spine. Your infrared vision shows the heat rising in her crotch as a bright red, incandescent with unfulfilled desire. Fulfill the Succubus Queen's agenda. You'd obey. It'd be so very easy to assimilate her here and now.

Still, the Haunted House had so much left to offer, and, after all, all you needed was her soul intact. And it would give you an excuse to search for Keith while you played hide-and-seek with Jenny. Perhaps Allegra would come after you too. You had always admired her strong will.
