XCOM: Viper's Interrogation

This story is a fanwork set in the world of the XCOM franchise (most recently produced by 2K), but does not require any knowledge of the setting to be enjoyed-- I specifically aimed to make it accessible to those who have never played the franchise while also trying to include references to the people, places, and politics of the setting. This story was requested by Hack_Blowfist and written by (breedorbebred).

A shrill beep preceded the mechanical hiss of the door opening, and Nilos tensed bodily. The interrogation room was near the centre of the facility, so it was a much shorter shot from here to where he vaguely recalled the exit to the outside world to be than from the actual prison cells. But the door was only ever open for a few seconds at a time, so his window for escape was short.

He leaned forward and pulled at the bonds holding his wrists, but the titanium-alloy bracers that held his arms behind the chair were just as inescapable today as they'd been yesterday. And the day before that, and the day before that.

There was no point exhausting himself on the futile struggle, so Nilos let his toned body go limp again. Better to conserve his strength for what was to come.

Two figures entered the room that had become the X-Com operative's personal hell, instead of the usual solitary presence. The interrogator wore his typical self-superior smirk and that shiny black lab coat, which Doctor Samuel had made a point of informing Nilos was, "Entirely waterproof, so I needn't worry about stains from all the inconvenient bodily fluids."

Not that he'd ever actually broken his captive's skin during the four-- or was it five now?-- days of interrogation. Nilos' captor, a real asshole of a wrinkly-faced alien, preferred to employ a combination of electric shocks and psychic assaults in an attempt to weaken the operative's mental defences. Exactly what the X-Com instructors had taught all of their psionic operatives to expect in the unfortunate event that they were captured alive.

Despite days of alternating physical and mental assaults, Nilos was proud to say that he hadn't broken. Hadn't given the bastards one shred of usable intel.

"Good morning, agent Nilos," the supposed-doctor greeted with entirely too much cheer in his voice for their location. Nilos was also pretty sure that it was actually close to the middle of the night, if his internal clock could be trusted. But after some number of days in the windowless Advent military facility, it was getting hard to tell. "I trust you're comfortable?"

Nilos settled back, directed his attention to the ceiling, and said nothing. His tactic so far had been to forcefully dissociate, like the deep meditative state all psionic operatives learned to utilize during their training, and he wasn't about to change it up now.

"Glad to hear it," the Advent interrogator went on as if his captive had answered. "I think you and I are starting to get close, Nilos. You've been keeping yourself shut away though, keeping those walls up... keeping me out. But yesterday you let a little something through, didn't you?"

Again, Nilos said nothing, but internally he winced. In the middle of a particularly painful stretch of interrogation, during which the wrinkled alien had alternated waves of psychic assaults with a barrage of questions about Nilos' mission, the X-Com agent had slipped up just a bit. He'd been asked about the Advent, about the enemies Nilos and his team had been fighting before his capture, and he had briefly pictured one of the Viper soldiers he'd seen during the struggle. The alien "doctor" had snatched the image from his head like a kid picking a four-leaf specimen out of a clover field.

"Do you think about the Vipers a lot, Nilos?" Doctor Samuel pronounced his name with an air of familiarity and camaraderie Nilos wouldn't tolerate from anyone but the closest of friends. Not that he ever let anyone close, of course.

"You felt such intense emotions while thinking of that Viper agent," he went on, content to monologue at the bound X-Com agent. "I don't know what exactly you felt about it, but I could taste the intensity. Anger, maybe, at having seen one rip apart your fellow agent as you fought your way to the doors. Or maybe revulsion at their almost-human forms?"

The doctor leaned in, getting his face entirely too close to Nilos'. But not close enough for the operative to headbutt his tormentor-- he'd learned from that mistake on the first day. "But I think it was fear, Nilos. And I don't blame you one bit, you know. They are quite terrifying creatures, the Vipers. I thought perhaps I would invite one along to try her hand working with you today."

The third individual in the room took the cue to approach, slithering forward until she took up Nilos' whole field of view. He meant to keep his gaze on the ceiling, he really did, but the man couldn't help but look down as the Viper approached.

"Nilos, may I introduce you to Ixthessil Ezhitho?"

She seemed perfectly typical for a member of her species. All Vipers had a degree of sameness about them, as far as Nilos could tell: the same four feet or so of humanoid torso atop fifteen feet of serpentine tail, the same brown-gold scales covering most of their body with patterns in rusty hues. The same long arms ending in claws, and even longer necks and with serpentine faces and flared hoods. They looked for all the world like hooded cobras that had been given a nearly humanoid shape to their torsos, complete with arms and hands with which they could manipulate tools and weapons with as much dexterity as a human.

As far as he knew, all Vipers were female. Or at least they looked female to him, with narrow "waists" that tapered in before flaring out into a pair of rounded "hips" that looked all too human to Nilos. Hell, they even had rounded protrusions on their chests that looked exactly like human breasts. The swells were covered in the same smaller, pale yellow scales as the rest of their underside-- which Nilos hadn't been aware of before this naked specimen had slithered into the interrogation room today.

He'd never seen a Viper outside of the light battle armour they typically wore, after all. But he had always wondered what the skin they usually covered actually looked like underneath. And this one seemed completely unconcerned with her lack of clothing.

"It's a pleasure to meet you, Nilos," the serpentine woman greeted him politely. For all that her mouth was the same kind of snout as you'd see on a real snake, with a long, snake-like tongue that flicked out to taste the air periodically, she pronounced the words eloquently and clearly.

But she did extend the "s" at the end of his name, drawing it into a slightly menacing hiss. More for the show of it than anything else, he suspected.

"I'm impressed that you've managed to keep your secrets from us so far, Nilos," the doctor complimented, "but letting your fear of the Vipers slip? That was a mistake."

His voice turned more menacing as he said that last, and he ended the sentence with a broad smile that showed too many of the alien's square teeth. A smile so vicious that it made him look almost human. Then he turned on a heel and strutted back to the interrogation chamber door, swiping the chip embedded in his wrist past an unseen sensor to let himself out. "I'm going to leave you with the Viper now, Nilos. I expect you'll have quite an... interesting time with my colleague."

And with that, the other man was gone, the door closing behind him to leave Nilos alone with the Viper, bound with his hands behind his back as the snake-like figure loomed over him.

"Let's have a look in that head of yours, shall we?" Her voice was cold, emotionless, but nevertheless held a thread of menace as she reached out to place a wide, ring-shaped device around his head. The Halo was a simple but brutal device of Advent creation, capable of creating bursts of psionic energy through the myriad of small electrodes that she affixed to the skin at either of his temples with surprising dexterity and grace. Nilos tried to shut his eyes as she worked, but he found he couldn't look away from her golden, vertically-slitted gaze.

Despite his shock at the sudden appearance of the Viper, Nilos was still a trained psionic operative, and his mind was a fortress. But not a simple stone-walled, medieval construction, no: Nilos imagined his mind as a vast, inhospitable desert, where an interloper could wander for a thousand years without ever finding the core of his thoughts. He was an endless field of sun-baked sand hiding innumerable threats just beneath the surface.

"A desert?" the Viper, Ixthe-whatever asked, her voice almost a purr as she looked at the small, holographic display on the front of the device. "How quaint. And not so threatening to a snake as it might be to a human, hmm?"

He flinched at that, never having considered that his psychically-empowered desert visualization might fail before a serpent where it had succeeded against every other mental attack. She tightened a bolt on the side of the device, pinching it tighter on his head but stopping just shy of actually breaking his skin.

"I am quite well-respected in this profession, you know," she went on, almost more to herself than to him. "One doesn't achieve a rank like mine without learning how to peel away a defensive visualization. Now, where are you hiding in there?"

The desert of his mind wasn't an endless flat plane, of course, and he loaded it now with defensive constructs: sheer-topped mountains with treacherous drops, poisonous scorpions and hungry desert predators. Quicksand, impassable gullies, sandstorms of razor-sharp shards of diamond, and anything else he could think of. Nilos was breathing faster now, a purely physical response to the snake-woman's proximity, even as he deepened his concentration.

Her tongue flicked out a few times, darting close to his face and making Nilos flinch as she subtly adjusted the Halo's settings. He knew how powerful a Viper's tongue could be, had seen one shoot out to grab an unsuspecting soldier to pull them into the snake-like monstrosity's deadly embrace.

"Mmm, I can feel your heart racing," she whispered. "Feel the heat radiating off of you."

For all her bravado, the Viper did no better at overcoming his defences than the human interrogator had. After a time-- minutes or hours, Nilos couldn't say-- she reduced the settings of the Halo to a low hum and let her reptilian hands drop to her sides.

"You are good," she said with a hint of what sounded like actual respect as Nilos fought to bring his heart rate back under control. "As accomplished in your psychic training as you are in the field. I read up on your mission, you know."

Ixthessil began pacing around him, undulating the long tailed portion of her body to propel herself forward in a circle that took her from in front of him to behind him to in front of him once more. "Part of a team of five, sent to retrieve one of your precious scientists as she was being transported by our soldiers to this very facility. You got your mark, but you didn't anticipate the ambush waiting for you, did you? Watched a fellow soldier die right there in front of you..."

Nilos did his best not to remember the pained sound his companion had made as he'd died. The bullet had pierced the soldier's sternum, so at least it hadn't taken long.

"And the only reason your remaining compatriots made it to the emergency evac was because you stayed behind to hold off the Advent's soldiers," she went on, still circling him. "You must have felt so very proud, playing hero with your noble sacrifice... but what was it for? The information I'm going to pull from you will be just as valuable as what we would have gotten from your scientist."

Nilos had to fight not to let a smile curl the corners of his mouth. Just as valuable as what they would have gotten from the scientist?

"What was it for?" he repeated, mockingly. "You really have no idea just what kind of asset you had in your scaled hands. That wasn't just some scientist... She was the lead researcher on Project X-Wave. My life, my companion's life... of course the mission was worth it. She's worth a hundred of me."

The Viper paused in her circling, standing directly behind him as he spoke. In so much as a creature without legs could stand, that is.

"Well, that is a disappointment." Her voice was still flat, and Nilos couldn't tell if she was upset or angry or just bored. "But at least I still have you. You'll make a lovely consolation prize."

Again her hands were on the sides of his head, and again he could feel the Halo starting to press against his mind. Coiling around it, threatening to squeeze... but you can't squeeze the life out of the desert. She could press down on the endless sands for a million years and never hurt the desert itself.

"I can feel you responding to me, you know. Reacting to my touch."

Nilos closed his eyes and gritted his teeth, trying to deny the obvious reality of his body. It wasn't that he wanted to react; he simply couldn't help it. His heart was beating faster in his chest as he felt her scaled hands caress his cheeks, warmth starting to pool in his cheeks and... elsewhere.

"I can feel your fear, your... wait..." The Viper paused, and he could picture with perfect clarity the way she must have been cocking her head as she regarded him from behind. "That's not fear that you're feeling, is it?"

The serpentine woman all but flowed over him, sliding around his legs where they were individually shackled to the heavy steel legs of the chair until she was looming before him again. The feeling of her thick, powerful tail pressing against his shin made Nilos' heart race even faster. She moved her face closer to his until her snout was mere inches from his nose and her yellow snake's eyes were boring into his.

Her tongue flicked out again, and this time Nilos didn't flinch when it brushed against the thick stubble on his cheek. "No, that is not fear at all."

The Viper stared at him, and he at her. He couldn't tell what emotion was shining behind her bestial eyes, but he knew quite well the taste of the fear swelling in his chest as his Viper captor realized what a powerful advantage she held over him. But the fear completely failed to outweigh the other feeling rising up within him.

"The good doctor picked up on your strong feelings towards us Vipers," she mused aloud, mouth still agonizingly close to his face. "The fool assumed it had to be fear that you were feeling, but clearly it is something much darker."

Her tongue flicked out once more, and her snout curled up in what looked like a smirk. "Tell me, Nilos... how long have you been attracted to Vipers?"

The human agent closed his eyes as she spoke his truth. There was no point denying it: she'd taken a peek in his mind, seen the fascination he held for the desert and all of its deadly denizens. Especially snakes. She could probably taste his arousal in the air, feel the way his body responded to her serpentine movements, the way he thrilled as her tail moved against him.

Ixthessil made another circle around him, slithering up over the coil of her own tail to wrap another loop around Nilos' lower legs, and all of his psychic training wasn't enough to keep his body from responding to the feeling of the Viper's powerful muscles bunching and shifting beneath her scaled skin.

"I've been stuck behind a desk for so long," she sighed, her serpent face pressed almost against his ear. "That's the reward for my years of excellence... a high-ranking desk job and endless reports to read. When Doctor Samuel asked for my assistance in this interrogation, I thought it would be a good way to blow off steam..."

She leaned back a bit, until her face was just far enough back that he could actually focus on the angled lines of her snout as she considered him. Again he wanted to look away, and again Nilos couldn't take his eyes off of the Viper as she swayed ever so slightly in front of him. She dragged a single sharp claw down the front of his chest and when Nilos shuddered, her wide mouth opened into an expression that couldn't be mistaken for anything other than a smile.

Her serpentine eyes flicked downwards for a brief moment before coming back to his face, and the flush on his cheeks deepened as shame joined with the warmth of arousal. He didn't need to look to know how obvious his erection was. He could feel it straining against the thin fabric all the prisoners of the Advent facility wore.

"But I could never have imagined just how much fun this would be," she finished.

Then all at once she released him, hand leaving his chest and long coils unfurling as she pulled back. It felt like he could breathe for the first time in an hour, and Nilos found himself drawing in deep lungfuls of cool air as he fought to regain equilibrium.

"I'm going to have to think about how to proceed, human." Ixthessil tapped a long, clawed finger on the chin of her serpentine snout. "Your captors will bring you back to your cell now. But I will be back for you tomorrow."

She turned to leave, swiping her wrist over the same section of wall as the human doctor had earlier to open the door. "And I'll be thinking about you until then, Nilos. Will you think of me too?"

Then she was gone, and Nilos was left in the chamber with a hard-on he couldn't even do anything about with his bound hands, waiting for the guards to come drag him back to his tiny cell. And he couldn't tell whether he was terrified or excited for what tomorrow would bring.

Another day came, with another pair of guards dragging Nilos to the interrogation room and another heavy set of mag-locked manacles securing his arms and legs. But maybe the Viper had put in a good word with the prison's security team, because today the guards transporting him hadn't even bothered beating him while he was bound. Not even a kick in passing.

He expected Ixthessil to show up shortly after he was secured and the other two had left, but she made him wait. Minutes or hours, he had no way of telling, but Nilos was left to stew in his own boredom, anxiety, and anticipation for an endless eternity before the door finally hissed open to admit the serpent-tailed Viper interrogator.

"Good morning, Nilos," she all but purred, once more dragging out the last letter of his name into a sibilant hiss. "I trust you slept well?"

Nilos sighed and closed his eyes, resolutely focused on ignoring the snake-girl today.

"I must say, I slept rather poorly myself," she went on, voice getting slightly louder as she obviously approached him. The familiar weight of the Halo settled into place around his skull as the Viper talked. "I was tossing and turning, thinking about you all night, Nilos. Thinking about what we might do today. Were you thinking about me last night? I bet you were."

Nilos ground his eyes more tightly closed as Ixthessil talked. He could tell from the direction of her voice that she was circling him again as he spoke, and the psionic operative had to fight to keep from turning his head to track the motion.

Never mind the fact that the head-mounted device made moving his head that far incredibly difficult.

And she was right, of course: Nilos hadn't been able to think of anything but the scaled woman all night. Her lithe body, completely uncovered by so much as a scrap of fabric. Her dry, hissing voice. The rasping sound of her scales rubbing over one another as she'd slithered over her own tail. The feeling of her powerful coils when she'd wrapped herself around his legs.

He had thought about her before falling asleep, and then dreamed of her once he'd closed his eyes. Dreams of claws and long fangs and scales brushing against skin. Dreams of the yellow, slitted eyes that had bored into his own with an intensity he'd never before imagined.

But the small cell with its transparent walls didn't exactly give a man the privacy he needed to get into the mood to jerk off, so he hadn't even been able to relieve the need that had been building within him since their last meeting.

A gentle, unexpected pressure against his chest made Nilos twitch in surprise, but there was nowhere for him to go as his captor ran a clawed finger lightly down his front. "You know Nilos, I have seen X-Com agents quail in the face of Vipers many times-- and for good reason-- but I've never seen anyone react quite like you."

Her voice was soft, almost a whisper, but coming from so close that the human agent found himself opening his eyes against his better judgment. He found Ixthessil's face less than a foot away from his own, her head lightly cocked as she studied him with those intense eyes. He wanted to turn away or shut his eyes again, but couldn't break away from the woman's gaze.

"I have to hand it to you, Nilos, you've actually managed to intrigue me," she went on, still studying him with that infinitely deep, yet emotionally flat, gaze. "And that does not happen very often."

Her finger was still lightly resting on his stomach, but began moving downwards again when she saw him open his eyes. Nilos wanted to pretend that the sleek, exotic snake-woman had no effect on him, but he could hardly deny the physical evidence of his arousal as Ixthessil brushed her clawed fingers against the front of his pants.

"And I get so, so bored in my office." Her voice was still flat, disinterested, even as she ran her fingertips up the length of his cloth-covered shaft to explore the shape of him through the fabric.

Then both of her hands were on Nilos' waistband, the only warning he got before she abruptly yanked the prison-assigned pants down far enough for his cock to spring up and sway in the air.

"Ah, there it is!" she cooed, a hint of emotion slipping into her voice for the first time that morning as she examined his freely-swinging shaft with evident interest. Nilos sighed with anticipation, pleasure, and no small amount of shame as the humanoid serpent took hold of his cock in her scaled hand. Her palm and fingers were softer than he'd imagined, and surprisingly warm. "Well, well, well. Aren't you just lovely?"

She stroked her hand up and down his length once or twice, the gesture more exploratory than anything else.

"I've just come up with a great idea about how you and I can spend our time together today!" Ix chirped with a devious smile that suggested whatever idea she was about to share was anything but spontaneous. "You're going to tell me all about this project you mentioned yesterday, this 'Project X-Wave'. And then I'm going to make your deepest... darkest... dirtiest Viper fantasies come true. Does that sound good to you, Nilos?"

He felt a light, prickling pressure against his mind as the Viper interrogator directed the Halo to begin the second prong of her assault. He had too much psychic resilience for a brute force attack to yield any benefits, but he could feel the device subtly probing his psyche. Looking for weaknesses.

"I don't know anything about the project." The words were out of his mouth before Nilos had even thought about them. He'd meant to stay silent.

"I doubt that's true, my sweet little human." Ixthessil moved her hand faster in her exploration of his cock, lightly squeezing him in a pulsating rhythm as she slid her fist from the base back to the head. A thick bead of precum formed on the swollen tip of him, and she smeared the drop of liquid around with her soft, scaled thumb, then spread that bit of lubrication around the ridge of his glans.

Nilos twitched as she stroked around the perimeter of his corona, and her smile grew even wider.

"I don't!" His hips bucked, though whether Nilos was trying to pull out of her grasp or fuck himself against her palm, even he didn't know. "Really, I don't!"

"You know, Advent leadership isn't quite what I imagined," Ixthessil complained, apparently shifting gear even as she kept slowly stroking her thumb around the width of his glans, teasing him until Nilos wanted to scream. "I put all this work into moving up, did some of the most cut-throat things you can imagine... Even literally, in one or two cases. And now here I am, stuck in upper middle management."

Something about the way she was stroking him off without even looking at his cock made it even better for Nilos. The way she seemed so detached, so aloof as she complained about work pressure, all while treating him like he was just a conveniently present piece of meat... There was something incredibly sexy about it to him.

"Don't you see how extracting this information from you could really help my career?" she asked, tone eminently reasonable as she brought the conversation back around to where they'd started. "Don't you want to help me... move up?"

"I don't know anything about the project other than the name," Nilos insisted. "They don't tell us grunts anything."

He could feel that subtle pressure on the back of his mind growing more intense as the Halo increased its output and some unseen prompt from her. But she didn't say anything to him, didn't even acknowledge Nilos' response.

"Hmm... you know what else might be nice?" Again, Ixthessil spoke like an idea had just occurred to her, even though Nilos had the niggling sensation that she was following a script she'd come up with well in advance.

But then she opened her mouth wide, and the sight of her jaw stretching into a bottomless maw disrupted any coherent thought he might have had. The human's breath caught in his throat as Ixthessil lowered her face towards his crotch, and his heart threatened to stop in his chest when she wrapped her dry, serpentine lips around the top half of his shaft.

For all that her scales were dry and barely more than room temperature, her mouth was perfectly hot and moist. The feeling of her lips and palette pressing against his cock from all sides was fucking heavenly, and that was before she started moving her tongue.

"Ah, fuck!" Nilos grunted as he felt the Viper's long, prehensile tongue push against the underside of his shaft before curling all the way around it. Her tongue was long and flexible, like a little snake in its own right, and Ixthessil started moving it in a way no human woman could ever compare to.

She gave a soft, "Mmm," of enjoyment as she bobbed her head up and down his cock once, letting his shaft slide into the tight confines of her throat. The throat of a snake, designed to effortlessly swallow even large prey. Nilos knew for a fact that she'd have no problem swallowing his cock, taking him right to the root without so much as gagging if she felt like it...

And then just as quickly as she'd begun, his captor moved her head back and released him, abruptly ending the pleasurable contact.

"The thing is, Nilos," she went on, seamlessly picking up their conversation where she'd left off, as if she hadn't just been swallowing his cock like it was a wiggling mouse being devoured by a hungry snake just moments before, "I really do think you know more than you're letting on. You're far too clever not to have some knowledge tucked away in that well-defended head of yours."

"I don't have the clearance to-- ah!" Nilos' rehearsed line faltered as the tan-scaled viper woman suddenly lunged forward and swallowed him all at once, lips sliding from the tip of his shaft all the way down to the base of him so that the end of her snout was pressed against his dark, curled hairs.

His cock had gone from swaying in the too-cool air of the chamber to being immediately embedded in her warm, tight throat, and the contrast was like night and day. He groaned again as the serpentine woman bobbed her head up and down, allowing her mouth to slide back up his shaft before diving back down to swallow every last inch of his hardness once more.

The heat of her mouth, the tightness of her throat clenching down around him, her prehensile tongue flicking down past the tight seal of her mouth to stroke the underside of his testes... She'd only been blowing him for a minute, but already Nilos could feel himself stiffening even more as a powerful orgasm began to build in the depths of his groin.

It was embarrassing to be about to finish so quickly, but in fairness it had been a while since he'd been with a girl even before he'd been captured and tortured for days. And Ix had gotten him so fired up yesterday before leaving him high and dry. And now here he was, a Viper's snake-like mouth wrapped around his cock like he'd always dreamed of, her cobra hood flaring with obvious pleasure and she applied more pressure and suction. Just a few more seconds of this and he'd--

Then her mouth and her hand were gone again, disappearing from his achingly -hard cock to leave the red, swollen member swaying sadly in the air again.

"The worst of it," she started again, picking up their conversation as the human man flopped his head back and groaned with unfulfilled lust, "is that I've seen how the higher-ups live. Peons and minions to do all of their dirty work, the ability to pick up and move to another location whenever they feel like it, deluxe comforts in their quarters. That's the life of luxury I want."

"I was... so close..." Nilos panted.

"I know, dear. It's tough being so close and seeing what you want without being able to claim it for yourself, isn't it?" She gave him another intense look, slitted eyes narrowing as she held his gaze. "It's not so much to ask for, is it? I just want a little bit of luxury from the bosses and their bosses. And from you... just a little bit about that project."

"I... I don't have enough clearance to know anything about it," Nilos protested, straining futilely against his bonds again.

"Is that so?" she asked, tapping a clawed finger against the bottom of her snout, where a human would have a chin.

And then she was moving forward again, her long tongue lashing out like a whip to wrap around and around his cock and bringing him back into a world of warm bliss. It was like getting a blowjob and a handjob and fucking the tightest pussy imaginable all at once, and almost immediately he could feel his body ramping up again. Tingling pleasure built at the base of his spine as she pumped her undulating, prehensile tongue up and down the top half of him as her lips slid lower down.

"Just like-- just like that," he ground out as the muscles of his body started stiffening.

And just like that... she released him again, and the orgasm that had been so close to sweeping over his body darted just out of Nilos' reach. He groaned again and twitched bodily, trying to find something to push against to get that last bit of stimulation he needed. But the Viper was out of his reach too, and she watched impassively as he humped at the air.

"But I know how tight-lipped your scientists normally are," she pressed as the human slumped in defeat again. "If the project was above your clearance, then you shouldn't have even known the name of the project or that it even exists. Operational security and all. Obviously, you're either lying about your clearance or people are telling you things they shouldn't have been. Which is it?"

"People... people talk..." he panted, and Ixthessil grinned so widely that he could see a glimmer of her white, white fangs.

"Yes, yes they do," she cooed, wrapping a hand lightly around his sensitive cock again. "People have been talking to you about things they shouldn't be, haven't they? And now you're going to talk to me about it."

"I can't. I can't!"

The Viper leaned back slightly, shifting the bulk of coils that she'd been resting on top of until the end of her tail became visible. She reached up with it like it was a third limb, caressing the scaled tip against Nilos' stomach before trailing it down to rub against his crotch, then his thigh.

"But you can, Nilos. You can do that for me, and then I can do something nice for you. That seems like a fair arrangement, doesn't it?"

She shifted closer until the scales of her thick tail were brushing against his leg even as her fingertips were brushing up and down his shaft. He was actively twitching with barely-contained pleasure, but the light touch of her fingers just wasn't enough to push him over the edge.

"Just tell me what Project X-Wave is, Nilos. That's all you need to do..."

He was so achingly hard, so pent-up, and the serpentine woman before him was so, so hot. Her fingers were wrapped ever so lightly around his shaft, teasing him with the possibilities of what she could do for him if Nilos just spoke...

"It's an experimental device!" he shouted, the truth bubbling up and out of him all at once. "It emits an energy field that turns off psionic powers!"

Ix wrapped her hand more tightly around his shaft, but resisted Nilos' attempts to thrust up into her grip as she frowned at him. "How? What exactly does it do?"

"It... I don't know how it works! I just know it completely nullifies all psionics within the area."

"All psionics?"

"Everything from kinetic manipulation to telepathy," he affirmed with a fast, desperate nods. "That's all I know. I swear, Ixthessil, I don't know how it works."

"If that's all you know, that's all you know," she told him with a pacifying smile as she started slowly moving her hand up and down his cock again. "You did really well, Nilos. I'm so proud of you."

Between the pre excessively leaking from his tip, Ixthessil's saliva slicking his shaft, and the softness of the scales of her hand, there was hardly any friction as she jerked her hand up and down his cock faster and faster. Pleasure spiked in his middle and raced up his spine, then reached a dizzying height when the Viper flicked out her long, dexterous tongue to lick the underside of his shaft, from base to tip.

The serpent used her tongue's grip around his cock to pull her whole face down, engulfing his entirety in one go again.

Some part of him quailed in fear that she would deny him again, but the rest of Nilos simply subsumed by the pleasure as her mouth and throat pressed down around his shaft. Ixthessil bobbed her head up and down on his cock and her tongue almost seemed to writhe and coil around his base. It felt like he was being jerked off, sucked off, and ridden hard all at the same time, and it took mere moments before his orgasm finally exploded out of him.

"Fuck-k-k," Nilos groaned out as his back arched and his already-hard cock grew almost painfully stiff in the hot, wet confines of her mouth. Then he was throbbing with unrestrained pleasure, the building pressure and need finally coiling up and bursting from inside of him.

Ixthessil almost seemed to smile at him from around his cock as Nilos shook and thrust up into her mouth. And she looked only more pleased with herself as the first fluttering rope of cum exploded from the tip of him to splash coat the backside of her throat. As a Viper, Ixthessil seemed to have little to no gag reflex, and she effortlessly swallowed the first streamer of cum while taking him deeper into her throat.

He cried out his pleasure and loosed another burst of slick heat as Ix bobbed her head even faster on his cock. What felt like a truly massive jet of cum pulsed from him to fill the back of her mouth as she milked his pleasure from him with every evidence of genuine pleasure.

Nilos watched in a feverish haze as the serpent hummed and smiled and threw her whole neck into the motion of blowing him. Her scaled tits bounced with the force of her head bobbing, and he could have swore the scales of her breasts parted slightly, splitting in a horizontal slit to reveal soft, pink nipples beneath as she groaned with what might have been her own pleasure.

Another burst and another came in rapid succession, until the sensations grew so intense that he couldn't keep his eyes open any more. Nilos squeezed his senses shut to focus on the pure pleasure radiating up his spine as she pumped and twisted her tongue around the bottom half of his shaft and sucked on the rest of him until he was almost too sensitive.

Only when he'd been thoroughly emptied, when she'd swallowed her fill and he was nothing more than a twitching and depleted mess, did Ixthessil finally release him. Nilos was gasping for air, panting as he tried to catch his breath after the nearly mind-breaking orgasm.

He opened his eyes to find Ixthessil's face so close to his that they were nearly touching. Her eyes were so large, looming like a full moon on a dark night, until he couldn't see or think of anything else. Clawed hands played along the bare skin of his hips for a moment before trailing down to grasp the top of his pants and yanking up firmly.

Nilos gasped as Ixthessil pulled his pants back up and over his cum- and saliva-soaked cock like she could hide the evidence of their deeds. And all the while, her bright yellow eyes pierced his own.

"Thank you, Nilos," she whispered, tongue flicking out to brush against his cheek and lips in a lightning-quick flash of contact. Was that a kiss for a snake, or was she just tasting the emotions on his skin? Before he could ask, the Viper grabbed a fistful of his shirt and smeared it across her mouth, mopping up the slick streak of saliva her sloppy blowjob had left behind and then standing back up as if nothing had happened. "You did well today, Nilos. I'll tell the guards that you're being very cooperative, and to give you an extra ration of food tonight."

Then she unhooked him from the Halo and turned to slither away without another word, covering the space between him and the hydraulic door before he could even blink. She swiped the fob embedded in her wrist to let herself out, then paused to turn her neck disconcertingly far around and give him a little smile over her shoulder.

"I'll see you again tomorrow, human. Dream of me tonight, will you?"

And then she was gone again, and again Nilos was left in his bindings in the uncomfortable chair. This time, his heart was sluggish with spent adrenaline, his shirt was wet with her saliva and his own cum, and his chest was heavy with a mixture of shame and humiliation and exhilaration.

What did Ixthessil have in mind for him tomorrow?

It didn't take him long to find out. It felt like Nilos had no sooner eaten his dinner-- a double ration tonight, which the human tried to pretend he wasn't embarrassingly grateful for-- and rolled into bed than he was being shuffled out the door again. Logically, he knew he'd done other things during that time, but in his anticipation and anxiety the intervening hours had felt like bare moments and he couldn't recall what, if anything, he'd done to pass the time.

And then he was secured in that same damned seat again, alone with his just thoughts for altogether too long before Ixthessil finally joined him.

"Good morning again, Nilos," she hissed in entirely too self-satisfied a voice. And this time, he had no idea whether she was telling the truth about it being morning or lying like the wrinkly-faced alien bastard had. Nilos had fully lost track of the passage of time, his internal clock as frazzled by Ix's contact as the rest of him. "Did you miss me?"

Again, Nilos said nothing, and again the Viper smiled like he'd given her an answer she wanted to hear. "I know I was thinking of you last night, Nilos."

The Viper held her hand out again, showing him the Halo, the electro-psionic interrogation device already active and flashing. He tensed reflexively, preparing his mind for the psychic assault, but Ixthessil just looked down at the device in contempt for a moment before setting it aside on the small side table where Doctor Samuel had kept all of his pain-inducing implements.

"I don't think we'll be needing this crude little thing today, do you?"

The serpent began her circular "pacing" again, slithering in a slow loop that took her behind Nilos where he couldn't see her. She dragged a clawed finger along his upper body as she went: first his chest, then his shoulder, before sliding it between his shoulder-blades as she stopped directly behind him.

Nilos failed to restrain a shudder as Ixthessil dragged that sharp nail up the back of his neck until her claws were lightly resting against the back of his head. And completely failed to hide the goosebumps rising on his skin when she leaned in so close that he could feel her warm breath against the shell of his ear. "I think you're going to be a very, very good boy for me and answer all of my questions again today, hmm?"

Her tongue flicked out and brushed his ear as she spoke, and Nilos shuddered again. The human X-Com agent resolutely clenched his jaw shut, but internally he somehow doubted he was going to be able to maintain his silence for long.

She stayed where she was behind him, almost cheek-to-cheek with the human as she wrapped her powerful arms around his chest. Nilos flexed his hands against the bonds, stretching out until he could just barely feel warm, dry scales against the tips of his fingers. As always, he longed to burst free of his bonds, but today escape was the last thing on his mind.

"I only have two questions for you to answer today," Ixthessil promised as those deadly claws trailed down his middle in two lines. The Viper's nails were razor-sharp, he knew, and she had plenty enough strength in those deceptively lithe arms that she could have punched her hands right through his stomach if she'd wanted. He'd seen it happen before.

But her touch was gentle, almost teasing, and his breath started coming in faster and faster as she drifted lower. Lower.

"The first question is the easiest..." Ix's fingers played delicately along the top of his pants for a moment before she seized the band and started sliding both layers of clothing down. "What was her name?"

"W-who?" Nilos stammered as the serpentine woman slowly slid his pans lower to reveal his hips. Then the top of his bushy pubic hair, which was increasingly in need of a trim as the days of confinement rolled by.

"The scientist we had in our... my 'scaled hands', as I believe you called them?" She slid his pants inexorably lower as she spoke, both words and movements almost painful in their slowness. The base of his cock was bared to the world now, the rest of it slowly being revealed as she inched the fabric lower and lower. "What was their name?"

The researcher Nilos and his team had rescued? Why would she even need to know their name?

"No reason you need to worry about, dear Nilos," Ixthessil whispered in his ear, and Nilos twitched in surprise. He hadn't realized he'd spoken that last thought aloud. Shame warmed his cheeks as it occurred to him just how much trouble he was in.

"She'll be safely tucked away by now," he hissed as the Viper finally pushed his pants down far enough to reveal the remainder of his shaft. "The security around our researcher will be doubled now. Tripled."

He was already halfway hard in anticipation of her touch, and Ixthessil gave an "Mmm," of obvious appreciation when his cock finally bobbed freely into the air. She left his thin, shitty pants bunched up around his knees, and he could hear the slow intake of breath and feel her tongue flicking out beside his face as she drew in his scent.

Her scaled, reptilian hands hovered just over his warm flesh as blood rushed to fill the length of him. Those clawed fingers, as capable of bringing intense pleasure as they were of delivering painful, bloody death, twitched as if she longed to touch him.

"If she's so well-protected," she breathed, so quietly that he had to strain to even hear the Viper's words, "then what's the harm in telling me?"

Again, Ixthessil's long fingers curled and reached for his shaft... and still she didn't touch him. Nilos groaned with need, fighting against his restraints to push closer to her, but still Ixthessil refused to close those last few inches between them.

"You can tell me, Nilos. Just imagine how good it will feel." Her voice was a soft, undulating presence in his ear. It reminded him of just how amazing it had felt when her tongue had slithered up to coil around his cock. She pressed her chest against him, crushing her scaled breasts between them as she undulated against his back as if she was fighting the urge to mount him right there. Was she really that aroused, or was this all just a show for his benefit? Did it matter?

"I don't... I can't..."

"It's such an easy question, isn't it?" The very tip of one of her claws brushed against a few of his pubic hairs as she darted her fingers in closer before pulling away again. The faint tickle was enough to have the man gritting his teeth, heart hammering in his chest as he fought the unbreakable hold of the manacles. "There's no harm in telling me this one little thing. I promise I'll make it worth your while..."

"Jordan!" he gasped without even thinking about it. A small part of him railed against his own weakness, fought against the idea of giving even an inch, but the weight of his need drowned it out. And like Ixthessil had said, what harm was there in giving the Advent the name of a scientist they'd never be able to find again, let alone capture? Really, it was like he wasn't giving her anything at all. "Doctor Jordan Amos."

"There you are," she purred. "There's my good boy."

And then her fingers were around him, finally cradling his cock again. He stiffened to full hardness immediately under her soft touch, straining against the smooth scales of her palm as she stroked him to life.

She closed her fist around him and pumped his full length once, twice, then released him again. Nilos' groan of protest locked in his throat as Ixthessil started moving, finally slithering back into his line of sight. Whatever he had been about to say was lost completely as he drank in the sight of her.

As apparent as his desire had grown, the Viper's own arousal was just as obvious. Those horizontal slits on her breasts had parted to reveal the soft skin beneath once more. Where before, they had been lines so subtle as to be almost impossible to spot, now they were spread open around her stiff nipples. The tender, pink skin pressing through looked nearly human, and he longed to rub his thumbs over the pebbled flesh.

"You did very, very well, Nilos," she purred as she crossed in front of him before continuing her circuitous path around behind him again.

Ixthessil was much closer to him now, her wide, serpentine tail pressing against his legs as she slithered around and past. She was wrapping around him, he realized, twisting a coil around his legs as she finished her loop and came back into view once more.

The sensation of a snake's tail encircling and binding him made Nilos' heart race even faster. But the way she came to a rest half on his lap with her chest mere inches from his face was even more intoxicating.

"Do you think you can keep being a good boy for me?"

Her body was pressed against his, her heavy coil on his thighs and wrapped around his legs, and it was all so much. The human felt like he could barely breathe, despite her not pressing against his chest at all yet. He longed to nod, to promise the Viper anything she wanted if she'd just reach down and grasp his cock again, but Nilos still had his pride. He was a psionic operative of X-Com, a defender of humanity. He wasn't going to give up all of Earth's secrets just because some snake lady had a nice pair of tits.

But Ixthessil was undulating against him as she rested half-in and half-out of his lap, and Nilos was so hard that he felt like he'd split right out of his skin. His eyes drifted down, almost automatically, to take in the view of his cock standing at attention, the pink-red tone of it contrasting so nicely against the light yellow colour of her underbelly scales.

Except there was a gap in the pattern of her scales. Another slit, just like the pair that had opened on her chest to reveal the pale shade of her nipples. But this one was vertical, a narrow opening running length-wise and just barely parted enough for him to get a glimpse of the vulnerable flesh beneath: pale pink and lightly glistening, labial folds just begging to feel him pressing into them.

"Oh, God," Nilos gasped as he finally got an answer to a long-standing question about Viper biology. Apparently Ixthessil had a pussy just like a human woman-- only a Viper's genitals were normally covered by a layer of scales that only pulled aside when they were aroused.

"Do you see the effect you have on me, Nilos?" she hummed as his eyes locked onto the sight of her soft, enticing flesh. "You're the first human to ever make me feel this way, you know."

Nilos shut his eyes firmly, trying to block out the hypnotizing sight of her moistness. Ixthessil looked ripe for the taking, her entrance so close to his hardness, but with his hands and legs bound he had no way of closing the distance. She may as well be on the other side of the globe, for all that he was able to get to her.

"Are you ready to answer my second question?"

Her voice was low, heady, almost gravelly with a very human-sounding lust. And it came from so close to his face, like her serpentine snout was almost touching him. Her scaled lips would be nearly against his mouth, he knew, those deadly fangs and that tantalizing tongue bare inches from him.

"It's just as easy as my first question was," Ixthessil promised as her delicate, clawed hands played down the front of his stomach. One came to rest against his abdominal muscles while the other continued its path south until she was lightly grasping his hard shaft again, and Nilos had to fight to keep from whining as she took him in hand. "And you did so well with the first question, so I know you can answer this one, too..."

Nilos felt the Viper wiggle her body closer to him, her coils tightening slightly on his legs as she repositioned herself until he could feel the warmth of her wet sex pressing against the base of his cock. "This Project X-Wave will need all kinds of exotic materials, I'm sure. All I need you to do is tell me where the supply drop for those materials is going to come down."

"I-- I can't," he pleaded, eyes still shut as tightly as he could. "I can't, Ixthessil..."

"But you can." Ixthessil pressed even closer, and Nilos couldn't keep his eyes closed any longer. He reluctantly looked down again, and was greeted by the sight of Ixthessil's lizard-like hand wrapped around the base of his cock, holding him steady as she pushed herself against him.

Nilos groaned with uncontained lust as he watched the Viper pressing her pussy against him, as he felt the very outer lips of her sex parting around the underside of his head.

"I just want to know where those rare, valuable supplies are going to land." Her words were like a serpent in his head, slithering through his mind and full of dark promise. He shuddered uncontrollably and stared at the sight of the snake-girl grinding her pussy against his shaft. "Imagine how good it will feel to tell me, Nilos."

The feeling of her was amazing. For all that she looked cold and dry and rough on the outside, beneath that Ixthessil was warm and slick and just waiting for him.

"Where is the drop site, Nilos?"

He strained against the bonds, trying in vain to thrust upwards and slide into her. Whatever movement he managed was neutralized by the hand on his chest and the lithe snake moving to keep just beyond his reach.

"Now, now," she clicked her tongue at him in chastisement. "You know that's not how this works. But if you answer the question, human, I'll make you feel good. So, so good."

"Ixthessil, please..."

"Don't you want to know how I feel on the inside?" The Viper's words were as poisonous as the venom that leaked from her fangs, Nilos knew, but still he listened attentively. Her hood flared with some emotion he couldn't identify, and she writhed from side to side as she leaned in even closer. "Warm and wet and tight... It's been a long time since I've been with a man, Nilos. Just tell me what I need to know and then I can give you what you want."

"I... I..." Nilos' mind was whirling, lust clouding his reason until the man could hardly remember what he was fighting against and why.

"Just tell me where the next supply drop is scheduled to be, and I'll slide your cock into my slick, Viper pussy. Ride you until you're screaming my name. That's a fair trade, isn't it?"

"The drop..." Why did he care what the Viper did or didn't know? Right now he could feel her slick labia sliding up and down the underside of his cock as she ground her sex against him, and the feeling of her proximity seemed so much more important than any stupid piece of intel. "The supply drop is scheduled for 11 a. m. on the fifteenth..."

"Yes," Ixthessil moaned, drawing out the 's' into a long hiss.

Still holding him steady, the sexy Viper lifted herself up slightly until she was hovering over Nilos' lap, her wet sex now directly above the human's cock. She started to ease herself downwards, and he could feel her slick lips pressing against his swollen head, wrapping around the very head and threatening to engulf him.

But not quite letting him inside.

"Where are the supplies being delivered?" She was panting now, as if her lust was intense as his own. Hell, maybe it was-- she was certainly wet enough.

"In the northeastern region, eleventh quadrant!" Nilos gasped out, all semblance of control lost.

"Yes!" she cried out, and terror gripped Nilos' heart for a moment as he realized how devastating a secret he had just revealed to the Viper. Knowing where and when the supply drop was going to be meant that she knew where the Avenger-- the enormous ship that served as X-Com's base of operations-- would be. But it was a very brief moment, because all at once Ixthessil was pressing down, and his entire world was reduced down to the feeling of hot, wet flesh wrapping around his cock and rolling downwards.

Her inner muscles gripped him like a velvet-lined fist as she slid down inch after inch of his hardness. "Yes! Yes!"

"Yes-s-s," the former X-Com agent echoed, his own voice drawing into a hiss not unlike the Viper's own as he drowned in pleasure.

The feeling of her was incredible. The heat, the slickness of her arousal, the tight squeeze of her grasping pussy.

Ixthessil took him in one smooth motion, sliding down his length until he was embedded to the root in her quivering grip. She paused there only a moment to adjust to him before she started moving again.

With no thighs to work with, the Viper instead had to use her serpentine lower body, flexing her long, thick tail to lift the upper portion of her body just slightly, until no more than half of him was still within her heat. Then she was coming back down, warm wetness rolling along his shaft to take him fully again.

Her hood spread wide to show off more of her neck as Ixthessil threw her head back. Nilos watched her tongue flicking out into the air with rapt attention, then let his attention drift down to where her scaled-covered breasts were bouncing and swaying in time with her motions. Ixthessil's once-hidden nipples were stiff with eagerness now, brushing periodically against his chest as she ground down on him.

"I knew you could be such a good boy for me," she purred, speaking as much to the ceiling as she was to the bound man beneath her. Both of her clawed hands were on his shoulders now, nails digging in ever so slightly to give her more leverage as she worked her way along his cock again, faster and faster now.

Ixthessil's words were interspersed with moans of rising pleasure as she gave herself over to the act of fucking, grinding herself up and down his length.

Each second in her warm embrace was pure heaven-- well worth the hell he'd endured already in this place. The snake's pussy felt like wet velvet, like silk of the softest quality imaginable wrapped over powerful muscles capable of squeezing the life from him.

And she was starting to squeeze now as she moved faster and faster.

"You feel so good," he groaned as Ixthessil undulated and writhed with her tail to grind herself back down his cock.

"Mm-hmm." Her purring pleasure only made the sensations more intense for him. After hearing the Viper speak with such a neutral, cold voice for so long, it felt even more empowering to hear her exulting in the pleasure his body was providing her now. "And you feel even better, Nilos. Just like-- Ah! Just like I knew you would."

Her face dipped in closer to his again, until they were nearly snout-to-lips, and Nilos had a moment of wondering whether she was about to kiss him or bite and kill him. But Ixthessil's long tongue just flicked out to brush against his chin, his lips, his jaw. He didn't know what the Viper could taste on him, but whatever it was seemed to please her, because she groaned even more loudly with each series of light, tongue-flicking kisses.

Up and down. The sensation of her slick tightness squeezing and pumping along the length of his cock was carrying Nilos closer and closer to the edge with every beat of his heart. The human strained futilely against his bonds again, yearning to wrap his arms around the sexy snake-woman so he could drag her down even harder onto his cock.

Maybe she read his mind somehow, or maybe they were just perfectly in-tune, because no sooner had the thought crossed his mind than the serpentine woman dug her hands more firmly on his shoulders and started to grind herself down even more forcefully. He could feel the sharp tips of her claws digging into his flesh, no doubt having punched through the thin material of his prison garb, but Ixthessil was careful not to pierce his skin.

Up and down. Already, Nilos could feel that tell-tale tightening at the base of his spine as pleasure started building in the centre of his pelvis. He gritted his teeth and fought back the feeling, resolutely refusing to let himself give in yet.

"Don't you dare cum before me," Ixthessil hissed, reacting again as if she'd read his mind. More likely, she could probably just taste his growing pleasure in the air above his sweating skin.

"N-never."

Up and down. Faster and faster. Her tight, convulsing passage moved no higher than maybe halfway up his shaft before coming slamming back down, making sure to keep him close enough that he wouldn't slip out. Ixthessil fucked herself on him with fast, deep thrusts that had him bumping against the deepest and tightest recesses of her slick passage as he struggled to maintain hold on the pleasure steadily building inside of him.

"Such a good little soldier you are." The Viper's voice showed the same struggle, the same strain of growing bliss as she squeezed his legs more tightly with her serpentine tail and pulled herself down onto him with enough force to make the steel frame of his seat shake with each impact. "Following all of my orders so well."

"Just... don't... stop..." he panted. Was he giving her an order in return or just begging? Nilos couldn't tell anymore.

Up and down. He was fighting with each breath against the growing pressure starting at the lowest point of his abdomen and threatening to radiate outward and upward.

Nilos could feel his cock swelling, thickening and growing even more sensitive with every second that went by, every hard motion of her hips that brought Ixthessil's tight, silken embrace slamming down around him. He thrust upwards with his hips as much as he could, adding his own momentum to her serpentine motions.

"S-s-such a good boy," the Viper hissed, the sibilant first letter being drawn out as Ixthessil's tongue flicked by to brush against his face again. "S-so, so good for me..."

The bottom length of her tail tightened and loosened around Nilos' legs and the chair's as she pulled her body up and down against his, but he could feel the rhythm of it growing more and more erratic. Her coils brushed against his hand as she writhed, and he tried in vain to hold onto her scaled flesh as she twisted faster and faster.

Up and down. The rhythmic rise and fall of her hips turned into fast, deep, erratic thrusts. As much as he was starting to swell in preparation for his imminent release, he could feel his Viper lover tightening and clenching in the same way.

It was a race to see who would get there first.

But Nilos had been trained to resist pressure and pain, to focus mind over body, and his willpower proved to be up for the task-- as it always had before the Viper came along. He gritted his teeth and willed himself to hold off, until at last he felt what he'd been waiting for.

"Yes-s-s!" Ixthessil gasped into the air for the third or fourth or hundredth time that morning. Nilos felt her body clench down around him, tail almost crushing his legs against the chair as her inner walls squeezed around him like a vice.

Up and down. Fast still, but with no real pattern to her movements. The Viper was thrashing on him now, writhing and twitching and slamming herself down onto his cock as what appeared to be an earth-shaking orgasm overtook her. He could feel the sharp sting of her nails in his shoulders and collar, maybe finally breaking the soft human skin there as she squeezed tighter and tighter.

The feeling of her tight pussy quivering and tightening as she rocked her hips to roll that tightness up and down his length finally proved to be too much. Nilos' fists clenched hard enough for his short, rough-edged nails to dig painfully into his palms as his own orgasm finally overtook him.

The building pleasure he'd been holding just at bay roared outwards with a vengeance, exploding up his spine to make his head spin and grow hazy even as it coursed up the length of his cock like tingling fire. He felt the entirety of that muscle clench and release as a wave of shuddering bliss rolled upwards, and he couldn't help the loud groan that burst from his lips.

Then he was twitching, muscle contracting and expanding in the quivering confines of her serpentine pussy. His whole body twitched as he thrust upwards as best he could. Then finally, the long-awaited, explosive release rolled outwards and upwards like an eruption of molten lava.

The snake writhing on top of him gasped as he shuddered, twitched, and loosed the first throbbing pulse of his pleasure. He could feel the weight and volume of it as it exploded outwards from his deeply-embedded cock, almost matched by the volume of his groan of pleasure. A thick streamer of cum poured forth, directly into her furthest depths right as the exotic, sexy Viper slammed her hips down hard to take him forcefully to the hilt.

Ixthessil was already so hot and so wet around his cock, but he soaked her with hot liquid of his own, and both of them gasped in synchronized pleasure.

After Ixthessil's remorseless teasing the day before, Nilos had half expected her to leave before his orgasm today. But she certainly didn't pull away from him, seeming to relish in the force of his climax.

She was barely moving her body now, shuddering and shifting just enough to keep up a jagged rhythm without ever pulling more than an inch up on his cock. But the twitching, squeezing rhythm of her pussy more than made up for it as she convulsed around him in time with his orgasm.

"F-f-fuck," he stammered.

His muscles tensed again in a rolling wave, from his testes to the base of his cock, then up his shaft itself. His cock clenched and released in time with the frantic pound of his heart, churning out another cascading wave of his pleasure. Her heat was wrapped so tightly around him, from his base to his tip, that every drop had nowhere to go but straight up into her, and he creamed the snake-girl with absolute bliss.

She twitched and writhed on him still, undulating in his lap like the serpent she was. Each motion of her tail and feminine hips brought her seizing canal rocking up and slamming down onto his still-twitching cock, milking his pleasure to higher levels.

Again he stiffened and throbbed, and again he released a heavy rope of cum up into his captor's tight pussy.

Ixthessil finally slowed in her movements-- not quite stilling, but just slowly rocking up and down on him as Nilos shuddered, twitched, and gave her every last drop of his spend.

She kept undulating like that a few moments even after he'd run dry, until the two of them were finally still and panting as they struggled to catch their breaths.

Then she was lifting herself up and pulling away from him. His still-hard cock fell from her slit with a wet slopping sound as she "stood" again. Nilos watched through bleary eyes as she straightened up and brushed unseen dust from her shoulders.

The small slits of her breasts slowly closed themselves again, her nipples almost reluctantly receding until that part of her breast looked no different from the rest of the surface. Her vaginal slit, he noticed, had already shut. The parted line of it was so subtle now that he could barely tell where it had been, except by memory of how that site had been giving him unimaginable pleasure just moments before.

There wasn't the slightest sign that she'd been aggressively riding and fucking him just moments prior. Her breasts and genital-region had returned to their previous looks-- and as far as he could tell, her pussy had closed up before a drop of his spunk had leaked out, so there wasn't even that trace evidence staining her.

The only hint of what they had been up to was a faint wetness around the camouflaged lips of her pussy, and even that she quickly wiped away with the edge of his shirt.

"I'd say this was quite the, ah... productive session, hmm?" Ixthessil asked with no small amount of self-satisfaction.

She had the decency to pull his pants back up and readjust his shirt before she left, although that may have been just to cover up the evidence of her activities. Fucking prisoners was probably not an acceptable form of interrogation in the Advent doctrine.

Effective though it had been.

"We'll have to meet up like this again soon."

And with that, the Viper turned and left him. The door opened with a beep and a mechanical hiss, and Nilos was alone with nothing to show for the experience but a slightly torn shirt, a dull ache in his legs from being squeezed so tightly, and the sweet afterglow of an incredible orgasm.

On the other side of the door and around a corner, away from the captured operative's ears, Ixthessil found an upper-management administrator waiting for her. He had the almost-human frame and unpleasantly wrinkled and bumpy face typical of his kin, and looked not unlike Doctor Samuel to her. He had his arms crossed as he looked her over coldly before finally quirking a hairless brow in her direction. "Well? Has your interrogation proven fruitful yet, Viper?"

Ixthessil paused for a moment, considering the irony of the Advent administrator's words. She almost laughed at the hidden double-entendre, but kept her serpentine face still and neutral as she glanced downwards before finally answering: "I'm not sure if my efforts have... born fruit. It will take time to get through to this operative."

The administrator probably assumed her downward look to be a sign of due deference, but the Viper's eyes had simply flicked down to her midriff as the two spoke of bearing fruit.

"Have you gotten nothing of worth from him then?"

"Oh, I wouldn't say that." Ixthessil's flared hood twitched on one side, which another Viper might have been able to interpret as an amused reaction. "I've definitely made some... headway. But, as I said, I will need more time with him. This information, learning of this Project X-Wave, is terribly important to those at the top, as you know. It's worth taking the time to make sure the interrogation is performed correctly. We wouldn't want to rush things along and risk losing out on the results."

"The good doctor noted that the prisoner is particularly afraid of members of your race. Is that true, Viper?"

"Oh, I would absolutely say that Nilos is... very strongly affected by my appearance, yes."

"Good. You have my permission to proceed, then." He gave her an authoritative nod and marked something down on the digital tablet he carried. "Take all the time you need to make sure this is done right."

"I'll take it slowly," she promised with another amused hood-flare. "You have my word on that."
