7. On the edge Bonus chapter

This is a "Bonus chapter".

There is no story.

There is no reason to read this other than utter viper-smut.

Enjoy...you pervert.

Everything was so sensitive.

The air that brushed against Nilian's skin, the heat emerging from his own body and the hug of his serpentine lover, and the slowly tracing claws that currently ran along his chest. Careful not to break skin, but rough enough to leave trailing lines of red on his stomach, chest, and all the way to the neck, where she cupped his cheeks from beneath. She looked above him like the great predator her species was born to be, smirking at the sight of the helpless human in her grasp.

She cupped beneath his jaw and pulled it upward to look at her. Both were lying on the couch and Nilian was laying atop the viper.

Nilian shivered against the enticing, yet dangerously sharp, end of her claws and moved how she wanted it. Eventually, his view had been lifted far enough up to see the green orbs of emerald stone, situated in a forward-facing manner, - indicative of the eyes of a natural predator - staring back at him. And that smile. Pulled into the very edge of her mouth, which ended at the hood, and revealed the pink of her gums.

"Enjoying yourself?" She inquired, partly teasing, but also making sure the man was feeling comfortable given the situation.

Nilian only nodded, as the claws below his mouth would have prevented speech.

Amira's smile grew even wider and a lot more mischievous. Using her tail, she pulled the human further up along her body. The globes of soft, scaled tissue were pressed up against Nilian's back and squished like the softest damn pillows the man had ever rested on. If not for the fact that the serpent was still planning something, the doctor wouldn't have minded just falling asleep in her coils. Though his erection, which was laying backward against his pelvis, would not have forgiven that ending.

Still forced to look up, the doctor grinned in a love-drunk stupor and Amira chuckled at the sight. Slowly, her tongue emerged from the opened slit and trailed overtop the man. It slithered in the air like a snake in its own right, the comparatively massive head of the viper followed it down and closer to the man's lips. Nilian's mind went wild with anticipation of a deep, sensual, and overtaking kiss. He closed his eyes when all he could see was the green of her eyes and the pink of her mouth. But it never came.

He opened his eyes again, only to see the serpent grinning widely a few centimeters away from him. He noticed how heavy his breaths were, how much he was beginning to heat up. He exhaled warm air to the snake and she enjoyed seeing the lust coming from him. But it wasn't going to come that easily, it seemed.

"Remember what I said yesterday? You gotta be a little more patient," she leaned closer, past his face, and whispered directly into his ear.

Her long neck pressed against him and he buried his face in the extended hood. She smelled wonderful, earthy, and excited. He loved the feeling of the tiny scales along her neck and cheek, brushing against his skin. She was still comparatively cold but clear heat radiated off of her and the coils around his legs had definitively warmed up.

A sudden sensation on his ear sent Nilian to arch his spine upward and a dull sound emerged against the serpent's neck. Amira lightly bit down on his earlobe again, only using the soft flesh of her maw instead of the venom-injecting teeth. Still, it sent waves of unexpected pleasure through the man's envenomed mind. He felt her tongue brush against the inside, chew on his earlobe, and breathe hot, steaming air against his tingling skin.

He groaned as one of Amira's coils sat atop his erection, squishing it onto his body and, most certainly on purpose, rubbing against his glans. But, as another and another followed, Nilian realized there was another reason. He was lifted into the air, Amira, stayed attached to his earlobe until she let go with a wet pop, then promptly laid back down. The serpent had slipped from beneath him and laid him on his back on the couch.

She hovered atop the man's chest, her stomach out and pelvis lined with his lower abdomen. Her breasts hung heavily from her chest and the winding tongue flicked in the air. Nilian couldn't stop his mouth from dropping open at the sight. Such beauty, the power to kill multiple men, emerging from a whole different race. But she was his, and he was hers. This tiny moment of intimacy was more valuable than any of the pleasure to come, just staring at the viper in her full glory. The eyes he so cherished looking into, stared at him with a knowing look, sharing the glance that spoke more than a thousand words could have done.

One of the long, slender hands of the incredible snake slithered up her stomach, tracing the lines of her abs and landing beneath one of her breasts. For her, it was just enough to fit into the four-fingered hand, though for Nilian it was almost like holding a football. Nilian's eyes trailed down and found the puffy scale, that had been pushed up and to the side, revealing the strangely shapes fold of the serpent's vent. Strange because it was not human, interesting for the exact same reason.

Maybe it was the attraction to the unknown, the hope to find love, kindness, and partnership with someone who never shared that culture. Perhaps it was an infatuation with the way they interacted. Or just the fact that no earthly woman could compare to this particular viper.

And what was that viper doing? She was staring the man down and sensually traced along her slit while kneading her breast. Completely unashamed, or perhaps even enjoying the man watching, she let her head lean into her neck, drop her maw, and her tongue slither out. A lewd expression, that also looked akin to someone drunk on something, plastered on her face as the seemingly infinite appendage ensnared one of her breasts. She squeezed tightly and the rest of her body shuddered in response. Then she let it go further.

All the way down to her other hand. The split-tip of the sensory organ flicked against the outer walls and the fleshy protrusion of her clit. She skillfully pulled with the thin end at the ball of nerves and hissed in accordance. Nilian could only watch, his penis pressed against her tail helplessly.

And finally, she entered her own tunnel. The pink flesh parted for its visitor and the man saw her visibly clench around the organ. The tongue got thicker and continued to disappear inside her snatch. Saliva, mixed with fluids of excitement, trailed down the serpent's sides and onto Nilian. Warm, sticky, clear.

Amira became so focused on masturbating atop the little human that her head was leaned backward in enjoyment. Her hands worked at her supple breasts and the tongue twisted and writhed deep inside her. She wiggled it around, turned it in many different angles, and pushed it in and out at an accelerating pace.

And just as she went at a speed of that would have caused carpet burn, if not for the slicking lubricant, she stopped suddenly. She pressed her fingers into her breasts and attempted to stifle a moan but failed miserably. Then withdrew the wet rope from her insides. It dripped with her own excitement and the coppery saliva, hanging in the air like some levitation-magic trick. She pulled some of it back inside and brought her head up to look at Nilian.

Leaking from the tip and the entire length Amira lifted her tongue above Nilian.

"Now, where should I put this to use?" She asked the man, though her speech was barely comprehensible with the open mouth and missing tongue. Her eyes shifted between his member and his mouth.

Nilian would have been fine with either. A long-awaited kiss and intrusion of her infinite tongue, mixed with a cacophony of tastes and sensations. Her fluids would be all over his mind, letting him taste the deepest parts of his partner. But his dick was aching, longing to be enwrapped in the winding, slick appendage. He nodded down and Amira followed his eyes.

"I figured," Amira teased and shifted her tail from his member.

It stood up on its own and remained resolute against the cold, teasing air. Then the air became warm, wet, and pressure met his glans. He looked down and saw the serpent over his upright penis. The coppery and generous amount of saliva dripped from her open maw and loosely hanging tongue. Amira, however, maintained a full view of the man as she drooled onto his shaft. Nilian could barely manage to keep up with the intense gaze the serpent shot him; she was a lot more comfortable showing her sexuality than the doctor and his uncontained reactions caused him to flush with red.

Amira breathed slowly and deeply, making sure that the warmth of her inviting mouth reached and coated his manhood in all sorts of sensations. The previously hanging tongue suddenly doubled, then tripled in length, and began wrapping around itself just above his cock. Eventually, she had created a winding, and constantly shifting, mass of soft, pink flesh. The forked tip hung from the end of this undulating tunnel and flicked back and forth above his glans. Nilian stared with wide eyes and tense legs as the thin piece brushed against him in the most gentle, caressing manner.

The dripping tongue winded down and began swallowing his tip into a moving, spiraling cocoon of wetness. He felt the pull and the urge to thrust into the pleasurable cavern of loosely coiling meat. And as Amira continued to lower her head down, the tongue dropping lower also. The sheer pleasure of the consistent and all-encompassing pressure caused the man to buck his hips and close his eyes shut, head pressed against the pillow.

Amira lathered the sticky fluids all over his shaft, ran the forked tip against either side of his glans, and slowly moved the mass of pink up and down. While her tongue remained snuggly wrapped around his entire mast, her head could still move independently. She couldn't speak but her eyes signaled paragraphs. Longing desire, a playful smirk, a low hiss, and that ever-present look of teasing lust. Her tongue continued to stroke from every angle, leaving not a tiny bit of skin exposed. But, as Amira brought her thin lips closer, she shuffled some of it away from the very tip.

Warm, steamy breaths of excitement played with his enraptured mind and hit every one of his most sensitive spots. The times between, cold air contrasted heavily against the following heat. And finally, she planted a soft, sucking kiss on his tip. She made extra effort to have it sound like a wet pop when she disconnected and looked back up, once again, completely unashamed.

Her impossibly dexterous tongue snaked down to trace his vein and reached all the way to his scrotum. Similar to how she fondled her breast before, she wrapped around the man's testicles and began maneuvering them around. Nilian groaned at the combined sensations of his shaft being completely encompassed, glans being teased by soft, sucking kisses, and balls tickled by an unearthly limb.

The snake followed by taking up the entire head of his dick inside the warm, thinly scaled lips and bobbing her head up and down very slightly. She kept him inside her sucking maw, as her tongue began to pick up the pace, stroking faster and faster while providing more than enough pressure.

His toes curled, his hips forced themselves deeper into the winding canal of flesh, wanting to go over the edges, empty into the mind-numbing mixture of wetness and meat, paint the serpent's maw in white. He let out a moan of her name in preparation and felt the intense tingle of orgasm run down his spine. Everything went wide and the only visual that remained were her eyes, a glare of anticipation in them.

A sudden pinch at the bottom of his shaft, at the base of his penis, and the sudden stop of the winding tongue. Nilian groaned in frustration, as he desperately bucked and thrust upward but found nothing to grind against. He looked back at her through squinted eyes and saw the tongue wrapped tightly around him. The serpent carried a sadistic smile, though a little apologetic. Nilian noticed his panting breath and sweaty forehead. Slowly, as he realized she was actually going to leave him dry, he let his muscles relax and felt the mounting pressure recede.

"That was mean," he said through gritted teeth.

"I told you to be patient and you go and just start fucking my tongue. I think you deserved that one," Amira replied and painfully slow unwrapped her tongue from his shaft.

True, Nilian had let himself go, in the drive for more pleasure. But the almost painful pinch had been rough and the following frustration led him to look at the snake with an overly offended look.

"Aww, come on now. Are you a little upset?" Amira continued to tease, letting her tip hang precariously close to his glans.

Nilian failed to muster a response, as the serpent suddenly unsheathed her fangs and lean close to the rapidly declining erection. She grabbed it with one hand and kept it from moving, as her jaw unhinged wide and released a hot breath onto the abused organ. The thin injectors of hallucinogenic venom twitched slightly in her mouth and brought her head down overtop his penis. Nilian felt excitement at seeing the puffy gums of her maw, knowing the pulling, swallowing muscles in her throat would knead at him and draw out whatever he had. The beckoning gullet beneath that consumed him before let his member regain the courage to stand once more.

Amira's eyes widened as his glans rested against the bottom of her open jaw. Her vision stayed locked with Nilian as she slowly and intentionally lowered the roof of her mouth, and in turn her fangs, closer to his dick. Nilian could only stare. A part of him wanted to begin rubbing up and down the warm, wet gums of his partner, but, remembering how it ended just a few moments ago, settled on letting her do whatever she had planned.

He felt the cold of her teeth entrap his swelling member from each side, locking him in place. A tinge of fear, having these sharp objects so close to his sensitive organ, was replaced by unmistakable excitement at the possible danger. Though again, he knew she would never intentionally hurt him.

She closed her jaw slowly until Nilian was trapped against the bottom by the encroaching fangs. And she just held him there, seemingly content to continue staring gazing into his eyes. Then, he felt her tongue emerge from the fleshy sheath beneath his glans and began to slick him with even more wetness. She lapped at his shaft, licked around the edges of his tip, and greedily captured the drops of pre-ejaculate. Spit dropped down the side of Amira's jaw and trailed along his length.

"A-Amira," Nilian pleaded, once again out of breath.

A smile curled at the long lips, a snicker escaped her throat and sent another wave of pleasure down the impossibly sensitive member. And finally, she pulled her fangs back and lowered her head completely down onto him.

Immediately, Nilian felt the oven-like heat, the lockbox of warm, undulating, lubricated flesh encompassing all of him at once. Her tongue was still wrapped around the edges of his glans and held his penis tightly against the bottom of her jaw. Her snout met his pelvis and the man felt the end of his member be taken into the snake's eager gullet. As if trying to draw out his cum by force of suction alone, she pulled and swallowed impatiently. As if thousands of bulbous fleshy protrusions licked along his shaft, he felt compelled to give in, right then and there.

But, a part of him feared that, if he showed this openly, the serpent would cut him off again then scold him as being too eager. Still, he could not hold back moaning loudly and clutching at the fabric of the couch. Though Amira offered something else to hold onto, the tapering tip of her tail landed in his palm. Nilian recalled the viper being ticklish here, so perhaps he could act a little using the nerves within.

He squeezed and the serpent instinctively tightened her coils and took a pause in the relentless assault on his dick. A tiny, hissing shriek emerged from her. It seemed, the excitement increased what she felt at the end of her appendage. Nilian tickled the scaled limb, played with it between his fingers, and pressed down. Accordingly, she gulped and pushed him against her soft maw, while her tongue encircled his glans slowly.

The previously denied release began to build faster and more powerful than before. Nilian basked in the anticipation of filling the snake's maw, of letting her wring him dry and leave him to empty out inside the fleshy walls. He felt himself twitch and his member swelled to rigid hardness. Surely, he couldn't endure anymore. He felt his balls pull closer to his body and raised his butt from the couch.

And, once again, it was his undoing.

Amira had probably known already, but still, the doctor's impatience alerted her to his plan of eager release. And she had no intentions of ending the fun just yet.

Nilian closed his eyes shut and prepared with a whimper as he felt the irresistible pressure rising into his shaft. The warm walls, slippery as always, beckoned him to go deeper, dared him to release his seed into the long, bellowing throat. The relentless teasing and nudging of Amira's tongue along his glans, the forked tip waiting at his tip and immediately taking whatever pre-cum emerged, was the final straw.

And then, it all disappeared.

Nilian gasped sharply, as cold air replaced the warm suction. The wetness was suddenly without pressure, the rising sting of climax still roared through his member and threatened to emerge regardless of where the result would end up. But that was also stopped in its wake, as Amira grabbed his cock with one hand and squeezed it like trying to choke someone to death. Nilian winced and whine his refused release into the air and shot his eyes open.

They locked gazes and Nilian rolled his eyes. He couldn't be mad at her, even if he tried. It was a matter that he was in a unique situation and Amira had settled on a game beforehand, one she seemed to be enjoying thoroughly. Her mouth still hung open, a trail of saliva connecting her to his twitching and slowly softening cock. She had been partly out of breath, too, it seemed, letting hot exhales be the only remnant of Nilian's receding pleasure.

"Ok, that was evil," Amira admitted, though the apology was undermined by a snicker.

Almost flaccid again, she finally let go of the manhood and let it drop back onto his pelvis. She looked up from it and at Nilian's red-hot face.

"Just a little more, I promisssse it'll be worth it," she hissed sensually.

Her tail escaped the doctor's grasp and made its way down to his stomach. Though no visible abs to speak of, the contours and rough outlines, from a more difficult time, were still there. She lifted her body above him, then shuffled below his waist as the muscular worm-like limb prodded against the softening organ of the man, as if pocking a dead animal.

When this didn't elicit a reaction, she turned to wrap around the member and apologetically began to stroke up and down. The cruel teasing, and lack of much-needed relief, plus the hazy effects of the cobra's venom, worked like a charm to make every single scale another source of unendurable pleasure. Still, the blood refused to invigorate the organ a third time, leaving the serpent to stroke at half-mast. This simply wouldn't do.

Although still a very pleasant sensation, the serpent's tail was not nearly the same as her swallowing mouth, dexterous tongue, or winding passage. And having experienced these heavenly pleasures, just minutes ago, left them snake to try something else to garner the man's attention.

Like being cupped in warm water, he felt something close shut around his scrotum. He glanced over the thick, scaled tail and saw Amira's maw completely sealed around below the base of his member. It looked a little derpy but the feelings it sent into him stopped any response. He felt her gums squeezed down, the unending tongue brushed along every single spot, and the utter warmth his balls were now encompassed him made him lean back down onto the pillow.

The warmth and wetness certainly aided in restoring his body's faith that he surely wouldn't be suppressed another time. He rose once more in between the scales of her tail and she supported him along the way with encouraging strokes. Her eyes were glued to the backside, where the main vein ran along, while she continued to suckle on his nuts.

Wrapped in the snug fit of her mouth and encouraged to grow via the consistent strokes of her tail, his member regained its size. Amira watched contentedly, her mouth still constantly moving in all directions, then closed her eyes and began moaning through any opening in the tight seal of her lips. Nilian saw that her hands were beneath herself and clearly rubbing her engorged slit.

Wetted with saliva and pre-cum, her tail flowed up and down, wrapping around certain parts and putting more pressure around his lower sides. Each one of the scales rubbed against the excited organ and moved from side to side as well as up and down.

Nilian felt his legs grow tense once more, though his muscles were beginning to get sore. He gripped onto the fabric and was about to close his eyes also. But then he reconsidered. Of course, letting the pleasure guide him would feel nice for a moment or so, but would also take control away from the serpent, an aspect she had obviously tried to emphasize thus far. Do, perhaps out of acknowledgment of that, or simply hoping to avoid a prompt end to his rising climax, he kept his view on her and controlled his body's need to push his seed out.

And Amira noticed this. Her green eyes opened to find Nilian staring back. At first, a little surprised, but a smile emerged from the unoccupied corners of her lips. In a way, the snake felt proud, whether that be of her ability to make her human listen or of Nilian's restraint.

Again, his spine tingled with encroaching release, preparing to launch a pent-up load into the empty air. But, luckily before it got unbearable, it stopped for the third time. Nilian wanted to be frustrated, complain that he had held off on teasing the serpent beforehand but, as she let go of his scrotum and rose above him once more, he saw a much better alternative than releasing onto the tail.

Amira's lower waist was drenched. A mess of sticky female ejaculate covered the scales in a glistening film of fluid. Her vent was puffed up to the maximum and the doctor swore he could see the air around it beginning to shift due to the immense heat. Amira still had her fingers near it, all were covered in the same lubricant. She made sure the doctor was watching before spreading the dripping folds open.

Overlapping pink, bulbous mounds on the sides of her walls, and a deep tunnel, which kept opening and clenching tight in no particular rhythm, seemingly winking at the man. The engorged clit stood tall atop the enticingly leaking vent. The scales around her entrance looked pinkish in hue and pushed aside to enable this gorgeous view.

Amira was just smiling, content, lustful, and anticipatory. She ran one of the clawed fingers along the opening, collecting a globe of the clear liquid. Once again, her tongue drifted from the small slit in between her lips and drifted down.

She wrapped the sensory organ around the finger and collected the liquid on the tip. Then it made its way to Nilian.

The man glanced up at the snake and she gave him a cocked head in response. Nilian accepted and parted his lips.

Amira took the invitation and suddenly struck forward. Her tongue arrived first, entering and passing Nilian's lips and immediately lathering the coppery fluids all over his tongue. The rest of the viper followed before the man had time to react. Her maw opened extremely wide, Nilian saw the pink of her mouth's inside, as well as the fangs, which shined in the roof of her muzzle, and the part where her tongue emerged from.

But, luckily, the fangs stayed out of the play, for now. Instead, her jaw closed a little more and only the thin lips met him. Still far too wide, she could almost enwrap his face entirely but seemed to settle at gnawing at the human's lips.

Meanwhile, the vigorously exploring limb of her tongue made quick work of the doctor's own, woefully inadequate organ. Then moved on to the man's cheeks, bulging them out and pushing as if trapped within. And, soon enough, slithered down his esophagus. He swallowed it down and felt her deliberately avoid brushing against him too harshly, as it would have triggered a gag reflex.

And the man, he loved it. The way his mind dissolved into millions of flapping butterflies, how his body moved in accordance to the serpent's will. The coppery taste clouded his senses and the smell of the snake, which he was forced to take in with every breathe as his mouth was blocked from doing so, smelled of utter euphoria. The glowing green eyes, which peeked beneath the slightly squinted eyes, were full of loving affection and uncontained desire. Her vertical pupils had widened to more than double their normal size and reflected the word perfectly.

His free member still stood at attention and the snake knew so. With her chest pressed against him at the neck, the soft breasts compressing inwards, the human felt the warmth from deep within her core.

Then her waist lifted. Connected via a strand of slightly viscous liquid to the man's thigh, her heating entrance displayed itself proudly. Nilian blushed at the sight, as she hovered over his swelled glans. As if knowing what lay above it, his dick twitched and bounced slightly, as globules of her natural lubricant dripped onto his shaft and slowly ran down his length.

The heated air was already mind-numbing, the tongue inside his throat had subdued most of his senses, and finally, he felt her wet folds against his cock.

He groaned into the serpent's maw as he was partly enveloped, though only at the very tip, and groaned with gritted teeth. Oh, how he wanted to bury himself in the winding passage right then and there, slam his partner down and reach into her deepest parts. But he wasn't the one in control. His legs were held down and his waist wouldn't budge beneath the snake's heavy coils.

And she just kept him there. Waiting at the gates, heat and fluid lathered him all the way to his base and leaked over his pelvis and balls. Lifting the scaly rump upward a little more and suspending herself above him, Amira began, painfully slowly, rubbing up and down. Each tiny movement sent rolling waves of pleasure into the man and to the serpent, too, as her folds were pushed to each side and her clit tickled against his glans.

The man could only moan in a suppressed manner, as his mouth was filled to the brim with the impossibly elongated tongue. He wanted it, needed it, desperately so. And Amira rested gladly atop his penis with that knowledge. Only the very tip was allowed to enter, giving the man's member-only a small taste of what was to come. Nilian squeezed his thighs together, closed his eyes shut, and just hoped the endless torment of teasing and suppressed orgasms would finally end.

And, finally, she obliged with his silent plea.

Slowly, ensuring that the doctor felt every bump, touched against every fold of her slippery walls, and was drawn deeper, only by the powerful contractions within. Nilian flexed his muscles and curled his toes, feeling the immense heat of the worked-up serpent, and his own immeasurable excitement. He felt the roaming tongue seize its exploration for but a moment and Amira had to take a breath, hissing loudly as she disconnected from his lips. Nilian could still only breathe through his nose and managed to catch the viper's hot in his nostrils.

Halfway inside, the dripping fluid had covered every single part of his manhood, while the heat threatened to melt his glans. Sucking flesh wanted to have him deeper inside, craving contact. Every bump contracted over his length and convulsed sporadically, fluids gushed from deeper within and leaked from the folds, pushing itself past his penetrating member.

She went lower, her eyelids fluttering as she felt her vagina's insides parting to make way and hugging the man tightly as soon as he pushed inside. More, she needed more. But not yet, the little human would have to prove his patience. So, despite the pleasure his member gave her and the feelings running up her body whenever she felt him inside her, she pulled back out.

Her insides, however, didn't want to comply with this order and did their very best to clutch onto the welcome intruder. Her body wanted him, her mind even more, but there was more psychological fun to be had. So, even with her walls contracting in long intervals against every part along his penis, Amira pulled herself back out. Until only his tip remained between her lips.

She shivered slightly at the loss of contact but stayed resolute as she looked into his face. Red as a tomato, sweat dripping down his forehead and her tongue shoved into him; such an adorably embarrassing sight. The serpent smirked, though it also looked twisted by the pleasure and hanging tongue.

Then, simultaneously with snapping her lips shut against his mouth, she speared herself onto his penis.

The man gasped, swallowing her spit and allowing more of her tongue to pile up inside him. She, too, was forced to shift her vision into the very top of her eyes, and her entire body suddenly contracted in unison, both inside and out. Her arms wrapped around him at the back of the neck and greedily pushed his head against her, her long fingers grabbing hand-fulls of his hair

Despite the restraints around his waist and legs, the man found the strength to push just a little further into the quivering entrance, just that slight bit more. And now, hilted to the very base, he felt hundreds of independently pulsating walls of ribbed flesh run up and down his shaft, while a more solid wall met his glans. She sucked on every bit, the oven-like heat within her deepest parts was painfully pleasurable, and the harder flesh enveloped the man's tip in a separate segment of her vagina.

She pushed her hips down onto the man and the couch creaked and complained, as she tightened her coils around the man. His mind had taken a backseat, only letting the feelings of unbearable pleasure and arousing scents and noise enter his consciousness. He groaned into her mouth and she hissed through the edges of her lips. Her tongue pulled back, unfurled, then moved back in and found new spots to press and push against.

Once more, even more slowly and drawn-out, she lifted her butt higher and let her walls clench around his member in a desperate, but ultimately futile, attempt at keeping him to herself. With every centimeter his length left her, the folds grew more adamant about their plea to let them keep his manhood inside. But the serpent was unrelenting and continued to pull. The stark contrast between the immense heat and constant pressure and the cool outside made Nilian's hairs stand on top of goosebumps and he hadn't to flex his muscles just to endure.

Lubricant and sweat ran down his shaft. Amira dripped onto him every step of the way until there were only the last few centimeters remaining inside of her. She felt herself clenching tightly against herself, now that there was an open space where his penis had just been.

Then, just as slowly, she pressed back down. He parted her internal walls, stretched against the sensitive nerves, the serpent didn't try to suppress a moan though it only resounded into the man's mouth.

Her claws shifted from pulling on his hair and pushing his head into her, to going down his nape. She put deliberate and rough pressure onto his skin. She paused, pulling back a little and shooting the man a questioning glance. Their minds were synchronized in desire and thought, the question was one of consent and the doctor nodded; whatever she was up to, he was ready and willing to play. Racking her claws into him, she left red lines and pierced his skin slightly in certain spots. The man shivered and flexed his back, as Amira moved down to his shoulder blades, where she put one hand on each side. The sharp-tipped claws dug into his muscle and skin, pulling his body against her chest.

Lifting her vent from his dick, it made soft, sucking sounds. Then, at the apex of his member, she slammed back down hard. He felt the heavy weight impact his hip and fluids spilled from the sides. Profaned sounds of gurgling hisses and suppressed moans filled the air, as she repeated again. Hard, crushing bounces, wet flesh interlocking and almost disconnecting, swelled organs adjusting to the other's form. It was downright feral, how the viper rode her little human, who could do no more than just roll his eyes into the back of his head and let out - given any other circumstances- unmanly sounds, as the massive predator bounced atop him with barely contained force.

Settling into a steady rhythm of fucking, the serpent pierced the man's skin once more, drawing a little blood. And Nilian? He loved every second of it. Every entry into the cavernous tunnel, the cold claws that dragged into him, the pain of the tiny incisions, his own blood running down his back, and the coppery saliva he had just decided to start swallowing; it all sent him down a tumbling spiral of lust.

His previously denied orgasm rose with a grudge, sending anticipatory shivers and tingles up the man's spine. With her own climax being coaxed from deep within, the serpent needed another change of pace. With the sound of someone sucking in an infinitely winding strand of spaghetti, she pulled her tongue from him. Nilian's mouth, almost numb from her taste and overwhelmingly invasive organ, still attempted to keep her roaming appendage inside with his own tongue. But, of course, he didn't succeed and the pink rope retracted all the way back into the serpent's sheath.

His mouth now empty, with only her soft gums and thin lips gnawing at his outsides, the man could breathe a little easier and his mind, though still clouded with overpowering sensations from venom and carnal pleasures. He opened his eyes and Amira did so, too, simultaneously. Their gazes locked in the knowledge that it would come to an end, however climactic, soon.

Without releasing his penis from within her warm insides, she brought her posture up. Their kiss ended with a trailing bit of saliva of indistinguishable origin. Her breasts were taken by gravity once more, still painted with the result of their previous escapade, and hung heavily from her ribcage. Her tight abs glistened with trails of sweat, running down the canal between the segments. With her pussy facing more forward than a human's, Nilian could see the engorged clitoris at its peak and his own member penetrating deeply. Now bent at an angle, the pressure only continued to mount and the serpent's thrusts carried a certain urgency.

His arms were not restrained and, although hazy due to venom, the doctor wanted to occupy his hands. He reached for her hips and ran his fingers across her scales softly. He moved his caressing touch more to the middle, where a belly button would be, and let one hand travel downward while the other made its way to her chest. The tall figure would have been unreachable for his arms, but the serpent appreciated the attention and gave in, by leaning forward and letting her breasts hang into his hand. The size filled his entire palm and he was immediately compelled to squeeze. At first, softly and playfully so, but he quickly remembered that both were close to finishing and moved on to a more rough squashing. This elicited the wanted reaction, as a sheepish and surprised sounding hiss escaped the panting snake's maw, while her insides clenched down hard on his dick.

The other hand slowly crept down to her nethers, making sure to only lightly graze her scales, until he reached his true goal. The large mound, in which his length disappeared into, was certainly sensitive, indicated by the quivering of her insides upon even the faintest touch. But the time for teasing was over, though Nilian planned to repay the cobra's game she had played today, at a later date. He pushed his fingers into the top of her soaking walls and began to turn and move them around a little, drawing moans and loud, whimpering hisses from her open gullet. Her insides contracted forcefully and sent shivers of pleasure into the man's nervous system.

Using two fingers, he snatched the hardened ball of sensitive flesh and pressed together lightly. Even just after that initial touch, her movement seized for a moment and she threw her head backward, her tongue wiggling out from the dislodged jaw. She couldn't pull it back in afterward and simply let it hang out from the side. Her bouncing continued, shaking her massive breasts. Her tail began to shake impatiently, and her walls grew taut.

Nilian's orgasm, held back multiple times before, rose like an erupting volcano. This time, even if it all stopped, the immense warmth, the slippery fluid, the intoxicating smell, the overwhelming feeling in his head, and the tight vice-like grip on his member, he was certain he would not be able to hold back.

"Cum for me!" Amira yelled, unconcerned about the neighbors or anyone on the adjacent floors.

The sound of a deflating raft returned, her tail pulled tight against his body, drool began to leak out from the side of her mouth and her eyes closed. Her thrusts became frantic, no longer conscious and instead just going off of instinct, repeating the movements that caused the most pleasure. Electricity ran through her entire body, beginning at the loins, making her constrict around the frame of the couch, like a sea monster taking down a ship. And, with one final push downward, she buried the man in her spasming tunnel all the way to the hilt.

Warm cum spurted from her depths, leaking from every orifice and coming out of every bump within. She squirted her fluids all over the man's stomach, hand, and penis, all becoming coated in the clear, sticky emissions. Her nervous system took over for her conscious mind, forcing her to grind her loins into him roughly, wanting, needing him to finish with her.

And the man had no choice but to comply. If it hadn't been for all that build-up, for the scents of lust, the amazing visual atop him, the impossible heat, the venom in his mind; the forceful contractions and arhythmical spams inside her devilishly wringing vagina, would have done him in with ease.

It was as if she was trying to choke his cock out like a prey animal, pressing down on every single one of his sensitive spots, pulling him deeper with lustful greed. Even though the two weren't compatible on genetic make-up, her loins didn't care, they wanted what he had to give and they wanted it deep inside them. Jolting with electrical pleasure, they milked and rubbed, licked and sucked, until the human was clutching onto the serpent's breasts for dear life.

His climax was expelled at the very edge of where he could reach, shooting a load that had awaited her release three times over. His muscles pulled taut against the steel-cable-like muscle of the viper, though he made little leeway against the serpent's orgasmic throws.

With every pump of seed, her walls regained some form of mind of their own and goaded out another, another, and another. She continued to flex and pull while he came, disregarding the overwhelmed groans of the man below her, who had also long abandoned trying to hold onto conscious thought. The sensitivity only made these warm, pulsating walls feel even more intense, coaxing the very last of his white emissions from him.

Though shorter, the man's intense climax left him stunned for an undetermined amount of time, in which her sticky walls remained a snug, heated fit for his slowly receding erection. The serpent had lost the ability to maintain a straight spine and collapsed on top of Nilian, her soft breasts squishing against his clavicle and limp neck slung over his shoulder. A low, satisfied rumble, followed by a deep hissing exhale sounded from above his head, as he felt her finally begin to let her powerful grip loosen up.

More time in the spent snake's coils passed, during which the man finally slipped from the vent, which would have gladly kept him there. Two kinds of orgasmic liquid flowed out after, as if having pulled a plug, covering him. Her body randomly shivered and her tail constricted around him tightly a few times, as his breath began to slowly calm and the hissing grew a little less slurred, the serpent regaining control over her outstretched tongue.

"See, that was nice, wasn't it?" Amira lifted her head above the human, gazing into his wide eyes with those amazing, vertical pupils, which just seemed to contain an infinite void of space.

Nilian only nodded.

"Then let's just stay here until you are fully back to your senses," she said warmly, smiling in that adorable manner. Then she leaned in for a kiss, though she kept her tongue only at the entrance to his lips. She pulled back slightly, shifted over to his ear, and, with her breath hitting Nilian in the neck, whispered.

"Just let me take care of you."

Damn, I actually just wrote 7 thousand words just on describing viper smut...And here I thought I had reached a peek in my life.

I swear this isn't what I am about (at least not entirely). I am just using this fic to go nuts with whatever comes to mind, while the others are for an actual story.

In either case, I enjoy the comments, what people think of this, and if they want to see me expose myself like this.

Thank you for your time.
