Well...

The duo slowly made their way through the back rooms of the store, checking the corners of offices, the ceilings of bathrooms and stockrooms from wall to wall. They were about to head back when it happened.

The busty sergeant grunted as she was hit from behind by something and fell to her knees. A something that had to be a person, judging by the hands that went straight for her breasts. She started in horror as she beheld the unnatural red of the fingers and the sharp nails puncturing the chemical suit, a feeling only enhanced when she felt pressure between her legs.

She was acutely aware of being without the rifle, which had clattered away with the impact.

“Gah!” she heard from left. She turned in time to see Henderson being held down by a succubus on his back while another slashed at the top of his suit. Seconds later the first ground the lieutenant’s face into the pussy of the second, who gyrated madly, her face alive in a rictus of desire. The tail of the first succubus rolled in and out of her sex as she watched her partner mash her cunt against the resisting lieutenant.

Sharon’s own suit had been rendered useless just as quickly. She felt a hand slip into her uniform and breath hot on her neck. The other hand joined the invisible presence at her crotch, rubbing her mound over her pants. The unseen demoness behind her cackled.

“You humans are so weak. Look how my sisters take what they want. Soon we will have another brother for our army.” The succubus calmly sliced Sharon's belt apart with a pass of her hand.

“And a sister to follow.” The murmur of her zipper lowering crackled unnaturally in her ears but was nothing compared with the demoness' lips on her earlobe and fingers tweaking her nipple and more hot fingers cupping her sex in her pants. The fingers slipped into the cleft between her legs, rolling insistently while their owner poured words into her.

“Do you like pussy? You'll eat it up soon like him. And any cocks you can find. I can't wait to see you two fuck.”

Sharon's stomach lurched and the succubi's eyes flamed as Henderson began to lap at the pussy before him, his tentative licks quickly turning into a deeper exploration of the demon's fiery snatch.

“Yesss, Already he cannot resist us. The power of the goddess cannot be denied. As you shall see.”

Sharon's arousal built as the busy fingers claimed their prize at last, slipping inside her moist pussy, filling her with an unceasing wave of unwanted sensations. Something across between a cry and a moan escaped her lips as her tormentor continued her work and the succubus on Henderson's back dismounted, crawling instead to her sister, who greeted her with a quite unsisterly kiss. Henderson ignored everything except the crimson pussy before him, snaking his tongue as far as he could into her folds.

“I want his cock,” the second demoness said. She flipped the lieutenant over easily and set to work springing his erect member from within the suit and his pants while her partner shifted slightly to restart the corrupting cunnilingus. As the demoness attending Henderson's cock began slurping it in a perversely loud blowjob, Sharon found herself eased back into a warm embrace, a second cock in her line of sight, or what looked very much like one.

She flushed as her eyes drifted from the nearby crimson phallus to the hellish creature enthusiastically fellating her superior officer, his slick cock standing at attention, thick and strong under the oral attack. Sharon closed her eyes, but this only focused her attention on the hand working her sex and the voluptuous body pressed into her back and the sounds and smells of sex. She subconsciously moved to meet her attacker's dexterous fingers as they sampled her, teased her, filled her.

“Oh fuck,” Henderson said. Sharon opened her eyes to see a magnificent succubus astride the lieutenant, momentarily distracted from the pussy above him. The two demons stared at each other as their mouths pleasured their sister's tail. For a while the trio just sat there, the succubi toying with each other, Henderson's cock swallowed by a crimson cunt, the lieutenant still under the hellspawn. The officer then reached out and smacked the ass of the demon on his cock with both palms.

“You want this pussy, baby?” she asked rhetorically, pulling herself away from her sister's delights. “All you gotta do is take it.” She wiggled on Henderson to emphasize the point. The lieutenant grinned and reared up, pulling her close across his lap. He thrust into her deeply, looking into her golden eyes, filled with a yearning he had never felt before. His cock luxuriated in her perfect cunt for what seemed an eternity until he slid out and blissfully thudded back in, setting up a rhythm.

The demon looked down on him with a mixture of awe and hunger as Henderson pounded her, his hands initially on her hips but then drifting over her body as they rutted, the succubus moving now too, gleefully returning his passion as he continued to head further into danger. The other succubus lewdly circled the couple while masturbating, cooing now and then at the show.

Sharon watched on helplessly, any hopes of altering the situation falling away. Still her unseen tormentor stoked her desire, thrusting and swirling and flicking her fingers in the soldier's pussy and across her clit. Sharon shivered against the succubus as she trailed a finger across Sharon’s skin, soft, menacing, seductive. The demon traced a line between her breasts, brushing her undershirt, down to her navel and stopped. She splayed her fingers across the sergeant's stomach and held her hand there, feeling it rise and fall.

Henderson crooked a finger at the voyeuristic demon as he bucked in time with her sister. The masturbating demon crawled forward and offered the soldier her fingers slick with juices. He lapped at them with a dark tongue while continuing to ram the other succubus. The hand at Sharon's pussy plunged ever deeper, syncing up with Henderson's actions across the room. She gasped as the demon locked eyes with her and grinned.

Sharon's mind reeled as her emotions tumbled over one another, terror overlaid with lust and anticipation and anger. However much she fought it, she found her arousal rising as Henderson single-mindedly plowed the demon with insane curves. The hand working her pussy made sure of it, and, Oh god, the other one was coming over, her unholy tits swaying ever so slightly.

“Why don't I give you a hand, sister,” she said to the unseen demon beneath Sharon. Cool air blew across the soldier's stiff nipples as the succubus deftly tore her shirt into a deep V and pushed her bra aside. Sharon muttered a curse as the she-beast's tongue flicked across a nipple while a hand cupped her other breast possessively. She moaned as lips circled and fingers rubbed her needy nubs.

One demon moved between her breasts, and another moved between her legs, and the third growled as she coupled with Henderson.

Across the room, Henderson rose with the demon still wrapped around him, his thickly muscled arms holding her in place. He tuned to face Sharon and paused, lewdly lapping the air as he thrust into the succubus slowly, her cheeks jiggling with each slam. Sharon fixated on his shaft plugging the demon relentlessly, its angry tint as it slid home again and again. He was obviously well past the point of no return now, his skin flushed and muscles bulging.

Sharon unconsciously ran her hands through her seducer’s pitch mane, her thoughts melting under the effects of the unholy sisters and the sight of Henderson taking the third deep as she spewed a stream of obscenities.

“That’s it, fill up my pussy with that big fuck stick. Pound my slutty slit, big boy. Really give it to me, harder, harder, fucking take me deep. Give me everything!”

Henderson grunted and put the demoness down, his monstrous cock popping free. He quickly spun her and pushed her onto her hands, burying himself in her folds again. He gripped her back as he thrust into the succubus again and again at a feverish pace.

And then it happened. Not without a sound, as their frenetic coupling was anything but quiet, but without any warning. The old Henderson burned away in a minute, his skin darkening to a hellish red in a wave crashing out from his needy cock. His canines lengthened into wicked fangs and nubs atop his head bit by bit grew to form a pair of swept-back pitch horns.

The fog of sex in her brain by now was so thick by now that it took a while to register the serpentine tail behind what had been Henderson or the set of heinous crimson wings that sprouted from his back like a gargoyle made flesh. The black cum seemingly everywhere as he finally finished, finally was finished by his demonic maker. His walk over to her.

The beast was just in front of her, as if time had lapsed.
