A proper Hunter would know when to quit. But by no means was this researcher ‘proper.’
She was a peculiar one; all of her research insisted on personal field tests and expeditions to monster-raided areas to spend long hours gathering minute and usually useless information about each species’ day-to-day rituals, behaviors, attitudes, and territories. The only thing that allowed her to stay in the research guild was the mass amount of information she gathered- for every hundred duds she would write up, there would be a report with crucial information that hinted at the lost evolution line of a species. So, she was allowed to stay, and the Anomaly Research Lab would reluctantly fund her one-man-army expeditions.
This one would likely be her last. Not because she was going to die, because she was about to break every rule about humane treatment of research subjects.
Her current study surrounded the mystery of Khezu socialization. Monsters, like all intelligent species, required socialization to survive, whether it was romantic, familial, parasitic, or cooperative. It was pretty easy to tell if a species was solitary or pack-hunters from general behavior observed from Hunters. Khezus were different. They were blind, cave-dwelling creatures who lived in complete darkness. Studying their behavior was difficult, and it was especially hard to study their domestic behavior. Their ability to stick to walls also meant that their nests were usually in hard-to-reach locations that couldn’t safely be studied.
When she offered to study this all on her own, the guild was doubtful. The information it would provide would be invaluable, but the chance of actually obtaining that information was nigh impossible. It was with great reluctance that they allowed her to journey off to one of the largest Khezu gatherings in the continent, but they had a mild hope she would come back with something to show.
Today, her plan was to test some of her theories. She had been studying the behavioral patterns of Khezu and had brought the supplies to survive in a specific part of the massive underground dwelling; a large, open cavern with humid air and a clearing free of stalagmites. This place actually didn’t house any Khezu families, largely because it was open and free of any hiding spots to safely nest. A few smaller animals would cross by the grounds- a couple of Remobras and maybe a pack of Baggi- but nothing notable was thought to happen here. That was until she discovered two Khezu journey out to this area, alone, engaging in strange rituals she had not yet seen.
Right now, however, she had most of her research and survival equipment placed near one of the walls. She wore pretty bare clothes for the normally freezing-cold caves, dressed in nothing but a high quality sleeveless beige top, her harness (which would normally be holding her back, but currently just hugged her back and chest,) leather shorts which only covered half her thigh, and thick hiking boots that came up her shin. This was good for ventilation, as the exposed skin allowed her to sweat some of the humidity of the cave off. It wasn’t a very safe outfit however. If she were to be assaulted by a pack of Baggi roaming through, she would likely not make it out of the cave intact- or even alive.
The strangest part of her ensemble was her ‘accessories,’ which included a lantern, a large potion vial filled with a strange off-white liquid, and the massive amount of anti-paralysis gel she was soaked in. She had lathered every last bit of her skin with it, lightly soaked it into all her clothes, and even slicked and tied back all the hair on her body with the gel. She was completely gooped from head-to-toe with the stuff. It was supposed to be used on leather armor and weapons, but she had the bright idea to just skip that step and apply it all over her skin. This was going to make her greasy for weeks, but she didn’t really care.
Counting down the time she laid in the center of the cavern, awaiting the schedule she studied for weeks now. Studying from a distance was not her style. She wanted to get hands-on experience with all her learning.
She didn’t have to wait long for a pair of fleshy wings to make its descent into the cavern, an elongated neck already searching for something to satisfy its appetite.
She held back a giggle, gazing intently at the giant wyvern only a few meters away. Now was her chance to get that beautiful nugget of information she desperately needed; to obtain definite proof that her research was fruitful.
She whistled loudly, causing the Khezu to bare its gums and display rows of crooked, bumpy lines of teeth. He quickly snaked his neck to face the source of the noise, carefully maneuvering with a stance low to the ground. Its wings stretched out like fingers, curling back to begin pacing towards her.
The researcher smiled as the male began to stomp towards her, taking her time with pulling the potion bottle out of her shirt and
popping
it open to allow it to waft through the cave.
To her, it smelled a bit herbal. Maybe something bitter, like brussel or kale mixed with chard. To the Khezu, however, it made it stop in its tracks completely. The monster perked up at a single whiff, slinking its head upward at attention. The amount of fangs it bared shrunk down in number, as the skin on the sides of its mouth pulled back towards his neck. Drool pooled down its mouth as it began to stand up a bit higher, raising its wings for a more cautious approach. His sticky tail swayed and curled in curiosity, expressing a more relaxed attitude but still putting forth a show of being willing to approach.
With every sign to continue flashing in her head, the researcher shifted her legs to sit on her knees, joining the Khezu in being at-attention. She swished the jar of ichor, carefully holding the bottom and side with her hand and positioning it over her head. The prolonged moment of being exposed to the scent caused a vibration to run from the Khezu’s head to his tail, making its growl sound more like a purr as it reacted to the sensations. She then began to pour it on her head, closing her eyes at the strange feeling but quickly getting over it as she moved the jar to travel over her body. With a careful hand, she had poured most of the potion’s contents on her whole body, now drowning in that strange herbal scent.
The ichor glided down towards the cave floor, all while she repositioned her legs to sit on her rump. She stuck both of her legs out towards the Khezu, feet together as she carefully tried not to disturb the viscosity of the liquid. She wiped the fluid off her forehead and slicked back her hair with it, moving her hand to her knee to spread her legs open and catch another glance at the monster.
The Khezu was only two feet away now- the shadow of its head looming over the body of the researcher as it purred away, puddles of drool landing to her sides. A heavy exhale escaped her chest as her body was consumed by warmth, her sweat unable to escape both layers of gel she had applied to herself. Once she looked between his legs and saw what came out of them, she was quick to tug on the bottom of her shorts and kick them off, revealing she was wearing no underwear and she had covered her nether areas in gel, too.
She could recognize her partner by sight- this was a mature, but young male, only about two years old. He had a few scars on the side of his right wing that were a slightly deeper pink than most striations on a Khezu’s skin. And, during this month, this Khezu was entering the deepest and most frustrating moments of its mating cycle- where it would spend two days flying around this plateau and showing off for any female who came by, usually spending around 20 to 30 minutes mating before failing to impregnate them and flying off in a huff.
Notes upon notes and sketches upon sketches had she made of this Khezu; she knew he showed signs of immaturity, strength, health, and virility, and so she wondered why his advances always failed to find a mate.
His long member, at least a foot and a half in length, glistened a pink similar to his tongue. It shined with the slick that pushed out from the opening that sheathed it, messily splattering on the ground next to its spit. As his chest got close enough to completely canopy the body of his partner, she could see it pulse along the shaft, a movement similar to a worm bunching up its muscles to extend forward making a slow journey through the extended length. In the center of the slender appendage sat a knot- no bigger than an inch wider than the rest of the meat it was attached to.
This ‘knot,’ she theorized, was not big enough yet to seal inside of a Khezu’s cavernous hole. What was likely happening to him was he kept mating with mature females who had already given birth- or perhaps, just ones with big openings- and failed to properly impregnate their wombs to constitute a good partner. He had a lot to give, but his staying power was not strong enough to obtain a partner.
Now being close enough to see the thing, she already began to map out the diagram of a living Khezu’s reproductive organs. Her legs splayed wide open as she laid back down, staring into the canvas of stretch marks that painted the Khezu’s underside. The Khezu rutted forward, expecting his partner to be a little higher up as he searched for an opening. Staring at the tip, which was now leaking some manner of fluid near her face, she imagined scenes of it kissing the cervix of a lucky Khezu wife and impregnating her, his knot puffing up to keep his member in place as he did.
The Khezu sniffed the air, noticing that he was floating his body above his mate. He retracted his neck slightly, taking a step back and crouching his body down to have his wings touch the floor. The researcher was now completely shaded by the Khezu, the flame of her lantern projecting onto his body and causing it to ripple with light. Their bodies glistened in this moment, all while the Khezu got closer and closer to her entrance.
Despite the monster’s massive size, their penises actually had long, snaking tips that only widened out past the knot, growing to a more normal monster-dong up near their waists. While a six inch circumference was nothing to sneeze at, the woman knew that she had a body that could handle it. With a low, cooing voice, and hips now raised to the sky, she whispered,
“C’mon boy. Come get some.”
A quick swipe from the tip coated her entire labia in mating fluid, causing a shiver to run down her spine. She didn’t falter from her pose, but she felt her toes curl as she prepared to be entered. The Khezu let out a human-like howl as it growled in delight, quickly pistoning its hips back to thrust again, the very tip of the tentacle punching her entrance and sliding in, very deep. She gagged in surprise as the cock pierced her, sending waves of shock through her whole body. Her well-built leg muscles tensed and braced for impact, as the Khezu rolled its hips in place and continued forwards. The researcher was dragged along the floor by its cock, desperately trying to get her legs to stay in one place as it buried its member another two inches deeper, writhing against her g-spot.
A complete lack of thoughts consumed her. This was a rare moment where she was so overwhelmed with satisfaction and physical sensations that her thoughts of research notes glazed over into a hazy spiral, her voice coming out of her involuntarily, matching the Khezu’s screams. Their screams echoed against the walls of the cave as the researcher was assaulted with the lewd noises of their bodies clashing together. A wet shlick resounded underneath the monster’s body as its hips moved back, dragging the woman’s lower half across the slate beneath them. The monster stomped its feet in delight as its curled tail smacked against the ground below, the sucker on its end firmly keeping its body in place as he went in for another thrust. The researcher was completely smothered by Khezu skin as it lowered its chest down above her head, the little prickles of static sliding right off the anti-paralysis gel, dancing down their bodies and creating flashing patterns of blue glow in the pale lamp-light. She felt and heard his chest heave heavy, the pattern of her breath matching his as their heartbeats pressed near each other’s crotches.
A firm PLAP drove her waist into the ground, the tentacle inside her turning and shifting to familiarize itself with the tight entrance. It mixed up her insides, both from the length, the force, and the behavior of the appendage entering her. Her breaths were nothing but moans, as another PLAP against her g-spot caused her to lose control of her bottom half and squirt all over the both of them. Her orgasm went unheard as two more SMACKS of skin drilled to the very depths of her pussy, guttural noises vibrating above her head as the Khezu found himself wanting more. This Khezu had never, and would never find a mate as tight and tempting as this one, the scent of her artificial pheromone concoction driving his libido wild and feral. There was nothing that could stop him from claiming this body, this hole as his .
The only thing stopping the Khezu from completely violating and opening her up, permanently damaging her insides was the fact that they had finally worked up to the knot. A firm doughnut shaped lump was now making short thrusts against the outside of her labia, not tapered enough to get past the hymen. The monster’s body had stopped slamming its hips as it rode the movements of his own cock, which continuously pushed in and out of her by sheathing and unsheathing slightly back into the Khezu’s slit. She gurgled in delight, coughing up another breath as the beast completely humiliated her body. She wasn’t even thinking about her notes, and she probably wouldn’t have the strength to write anything down once he finished this ritual. All she could think about is how she felt like that beautiful female Khezu she imagined only minutes ago, ready to be knotted and impregnated like the lucky wyvern she was.
An ear-piercing whine came from the extended throat of the male Khezu as he finally pushed his hips forward again, taking two steps forward and dragging the researcher’s hips up into the butter churning position. She was ready to be overflowing with monster seed, tears and sweat pouring from her eyes and clouding her vision. She was completely blind as the beast rolled its hips forward and released throbbing loads of Khezu sperm into her body, immediately filling her up and nearly flowing out. His little knot pushed against the outward flow, forcing her inner walls to take on a few liters of cum inside. Much of it gushed past the knot and leaked down her ass and waist, glazing her stomach and back in Khezu cum as it soaked into the ends of her shirt. She did get an extra few milliliters fuller from the knot’s help, her athletic stomach bulging with his cock and his seed. If she had the strength, she would reach out her hand and touch the bump, feeling the throbbing from the outside.
The researcher’s eyelids glazed over in bliss, happier than ever to have her research go so well. The Khezu would be keeping her like this for at least 10 more minutes, trying his best to make sure his sperm goes deep enough to take to an egg in her womb.
The two of them growled happily, overjoyed to have finally found their life-long mate.
