Tonight was going to be Ushitora's big night, but she showed no signs of nervousness. She had no reason to. The holographic readings on her bracelet were all nominal, of course, but she checked on them to make sure that all sensors were on. The technician didn't want to lose a single bit of data for her research.
The indigo taur hybrid stretched her arms above her head as she calmly made her way through the space station, looking up at the name 'OSIRIS' that seemed to be plastered on every other screen. There were countless places throughout the galaxy where its citizens could indulge in their desires, and Osiris happened to be one of the most popular establishments when it came to adult entertainment. There were lounges, nightclubs, cabarets, strip clubs, motels...
But what really made Osiris famous were its orgies. Patrons were bound to stumble upon one of the many orgies simultaneously taking place in the station, just a few steps away from any other facilities – and that was by design. Mainly for that reason, Osiris was known as the 'haven of endless vices', or more succinctly, the 'sex station'.
For Ushitora, it was the perfect place to conduct her test on her 'hammerspace' tech. As a scientist, she'd done her due diligence, making sure that there wouldn't be any trouble with the experiment she wanted to run. She'd consulted the staff, who had told her that 'anything was fine, as long as it was consensual'. All the better for her, since she was looking for willing subjects anyway. And as far as everyone else was concerned, she was just another customer.
Except for her bracelet, the hybrid walked fully naked through the hallways, same as most people in Osiris. Glancing from the front, Ushitora may have looked like a regular 9' anthro tiger, with her indigo fur and white stripes on her head, back, and limbs. Her front-side was rose-colored, from the bottom of her snout, along her round breasts, and down her entire ventral side. But her body continued past her digitigrade feline paws, extending back to her bovine features that gave her a distinct taur appearance, complete with a hoofed pair of hindlegs and a big pink udder hanging near her groin. Her vagina was at the very back by the haunches, somewhat oversized in comparison to the rest of her body. The slit led to the womb, in her lower half – its location was a fact that she was acutely aware of, thanks to her experimentation.
Despite her unique physique, she easily blended with the crowd in this particular section of Osiris, which was frequented by customers of all species and body sizes. Plenty of eclectic people came here for exotic experiences. She figured that a diverse crowd would afford her the perfect opportunity to find test subjects, both large and small – while also providing said crowd with the once-in-a-lifetime experience they sought. Ushitora wanted to see how her womb would perform when put to the limit, and there was nothing like hard, empirical confirmation from a real orgy.
The hybrid wasn't nervous, but excited. It was her big night.
***
The room that she randomly chose to enter felt too spacious, but only because it had to accommodate people even larger than Ushitora. Surely enough, she could spot all sorts of anthros inside. Most of them were smaller than her, and having fun in a cluster near the center. In the middle of the group, sat a yellow four-armed bear-like male, the largest person in the orgy by a long shot. There were also a few stragglers, likely taking a short break in their night of nonstop sex. In total, there should've been about a dozen others in here: some with fur; some with feathers; one with scales; and even a pair of humans.
The tiger-cow smiled from ear to ear. She couldn't have come up with a better random sample herself.
While most were too distracted – having their own fun to notice Ushitora walking through the automatic door –, a 6' snow leopard approached her. He was sipping from a can of Osiris's special energy drink, tailor-made for replenishing one's sexual stamina. His eyes gaped once he spotted Ushitora, immediately taking an interest in her. He chugged down the rest of his drink before rushing to her side, staring up at her sunny smile, though he couldn't help but steal a glance or two at her udder.
"Oh, wow! Is that a real udder?!" The snow leopard brought his paws close to it, but hesitated just an inch away from touching the pink teats. "Ah, sorry. I should've asked you first–"
"You can touch it." The hybrid said with her bubbly tone. "I don't mind!"
The spotted gray cat beamed, and let his digits squeeze into the smooth skin sagging between her legs. Ushitora saw how his limp dick started to harden again, getting excited that he got to play with her least feline bits. It was an unexpected start for the evening, but she decided to enjoy the snow leopard's touch. This was an orgy, after all, and she still came here for some kinky fun aside from her research.
The feline anthro began enveloping his arms around it, and she could feel his purrs vibrating her sensitive skin. "Prrmmf... I've never seen anyone with a cow-taur mod in the sex station, but I'm honestly into it~..."
"Oh, it's not a mod! That's how I really am." She corrected him.
Body modifications – or mods, for short – were very common, especially with Osiris's clientele, who mainly used them for the purpose of enhancing their sex. And mods could be temporary or permanent, or very obvious or discreet. In the case of the snow leopard, there wasn't any way for Ushitora to tell at a glance if he had anything installed. In turn, he couldn't tell that she actually had installed a mod on herself, but she had no intention of keeping it a secret.
"Really?" He asked with some skepticism, taking more care to feel the texture of her natural udder as he pressed his body against it. She could feel his cock continue to harden as he slowly pressed his crotch against her. "No mods at all...?"
"Well, I do have a hammerspace womb mod that I've been meaning to try! I made the tech myself."
Ushitora had forgotten to explain what a 'hammerspace' actually meant. She was so absorbed in her research that she often assumed that others knew that it was a theoretical pocket dimension with a capacity that far exceeded its apparent volume. Or was theoretical – until now.
But from the snow leopard's wide-eyed reaction, he was probably familiar with the term. He took a step back and stared at her pink labia between her haunches, but didn't approach it. Instead, he turned to face the main group at the center of the orgy, and called someone without raising his voice.
"E'chii'a! Come here!"
The one who stared back at him was a tall anthro, with her maw wrapped around the towering cock that belonged to the taller multi-armed yellow one. The alien girl had protrusions along the side of her head, while her two-toned had a bluish-gray tint to her head and back, and white on the front. The texture of her skin resembled that of a manta ray. Ushitora couldn't recognize her species, but her fish-like tail and plump breasts suggested that she was some sort of shark-mammal hybrid.
E'chii'a unwrapped her mouth from the large penis head, spitting it out with some effort, before walking towards the snow leopard. A few new pairs of eyes followed the sharkoid anthro's gait towards the newly-arrived Ushitora. At about 10', E'chii'a had to look down and inspect the tiger-cow's indigo body, before her pupils eventually stopped at the feline fondling her udder.
"What's up, love?" She asked with a sweet and quiet voice.
"This taur lady – er, I don't think I asked you for your name –, she said she's got an actual hammerspace mod in her womb! And that she made it herself!"
"It's Ushitora," she happily answered, "and yes, I did! It is fully functional."
Instead of the snow leopard's skepticism, E'chii'a's smile opened wide in delighted surprise. "Really?! Oh wow! You have no idea how long I looked for one! I even tried to make one myself, especially since Lukey got his hyper cock mod," she pointed at the snow leopard, "but it seemed impossible! So I settled on a stretching mod in order to fit him. Tell me, how did you deal with the mass compression?"
Ushitora smiled, happy to find another mod technician and answer her every question. "I didn't. I used bio-nanotechnology to generate anti-relativistic quantum fields from existing bosons, which contracts space and creates a cascade effect, entangling more matter without ever collapsing its density. And it's all safe and organically-compatible!"
The gill-less fish woman seemed to take a moment to process the technical jargon in her head. "I never thought of that...! But that cascade effect can't repeat itself forever, can it? There has to be some limit to how much mass it can contain."
"Probably, but I haven't found the plateau of effectiveness yet! So I came here to try it out and get some data, and see if I can't reach my limit. How would you like it to help me with that?"
E'chii'a gasped at Ushitora's suggestion. "Y-You mean, you want me to go into your–?!" She nearly jumped in joy when the tiger-cow nodded. "Yes yes YES, I definitely would! Right away! That sounds so exciting and hot! You don't mind, love, do you?"
She turned to the snow leopard, who was getting even harder at the thought of his tall girlfriend disappearing into someone as big as her. His penis was already twice its normal size, and still growing thanks his hyper cock mod.
"...Only if you go feet-first." He asked with a blush to his cheeks.
E'chii'a grinned, having a good idea of what her boyfriend had in mind. Ushitora had begun to move herself, getting in position with her hind towards the alien shark. Her oversized vulva didn't seem big enough to stretch over the other woman, since both of them were about the same size – but thanks to the hammerspace mod, that wouldn't even matter.
But E'chii'a still asked delicately. "How is this going to work? Do I just push myself in...?"
"Just lie on the ground," Ushitora explained, "and bring your feet and tail to the entrance. I'll do the rest!"
They were both extremely excited, but the taur did a better job of concealing it. The anthro lied on her belly and breasts – since Ushitora didn't specify –, flexibly raising her legs so that her feet were pointing up. Since she wasn't a true shark, E'chii'a lacked a dorsal fin on her bluish-gray back. Slowly, she aimed her toes towards the vagina, introducing one foot into the warm folds, then the other.
Ushitora's body accepted them easily enough, but she still shivered at the abrupt touch. The muscles in her canal were used to welcoming any willing prey, and already they began tugging and compressing at E'chii'a's limbs, before she even brought her tail fin closer. Once she did, it was slurped into the entrance alongside her legs, slowly being pulled inside. At that moment, Ushitora's bracelet made a little 'beep!', as her nanotech sensors automatically began recording data.
All three of them paid it no mind as the surface-dwelling fish disappeared to her ankles, not making so much as a bulge so far. E'chii'a instinctively thought that her tail might've proved difficult due to being so thick, but the bovine vagina tugged at it with ease. Meanwhile, Ushitora focused on enjoying the unique texture of her willing prey. Her skin was so smooth, with the almost imperceptible ruggedness of denticled scales that scratched her folds pleasurably. Her vagina craved more, massaging her prey down as if returning the pleasure it received. The anthro was still far from the womb, which was already wide open for the arrival of its first guest.
E'chii'a couldn't even feel any tightness other than her legs being pinned together, only a creeping warmth and wetness making its way to her knees. The grip of Ushitora's canal was soft, indicating that her insides were much more spacious than they appeared. A hammerspace womb... The realization was dawning on her – the taur had achieved the impossible! And she had the privilege of being the first person in the whole galaxy to experience it firsthand. It felt wonderful for her – and, judging by the tiger-cow's quiet moans, it was wonderful for Ushitora, as well.
As she continued to be pulled backwards thigh-deep, she remembered someone who still wasn't in on the fun. Her snow leopard boyfriend was simply watching, in amazement, as the shark-like woman was devoured by the technician, with his modded penis finally reaching its full hyper potential from enough arousal. E'chii'a planted her palms on the floor and raised her head to match that large member just short of the 4' mark.
"This is why you wanted me to go feet-first, right, love...?"
And she gave a slow, long lick along the underside of the whole member, getting the spotted feline to moan. She had a couple of mods that gave her a long tongue and a stretchy maw, just to let her do some oral play with hyper dicks like her boyfriend's. Though these were normally used as mods for vore – an act that wasn't taboo in Osiris –, the snow leopard's cock was enough of a mouthful for her than any real prey. She brought her jaws to the tip, pushing it between her teeth and swallowing immediately, to let the engorged shaft infiltrate her throat just the way she loved it.
The snow leopard gasped, never growing tired of the tightness that E'chii'a's esophagus provided around his cock. She easily swallowed more of his whole length until her snout met his crotch, letting his cock fully bulge out in her bluish-gray neck. The alien shark even raised her arms to appear as if floating midair, thanks to being hoisted – by the cock propping her upper body from inside, and by Ushitora's pussy pulling on her pelvis. The sight of his girlfriend being sucked into another woman and disappearing from sight – without making even a single bulge under that belly or udder – was making him even hornier, and he started to thrust in and out of E'chii'a's throat.
The esophageal walls were still narrow, but stretchy and slick enough that she could let the snow leopard fuck her maw. Each time the hyper cock pushed into her, she felt her body sinking deeper, being surrounded by more of the hybrid's warm walls. The tunnel kept pulling on her, and the feline's humping helped push her in, all while her throat relaxed and expanded at the rhythmic insertions.
Fully trapped between her boyfriend and the inviting womb, she kept her arms aligned with her body, letting them slip inside along herself. It let her feel Ushitora's walls against her fingers, though they were just as she'd expect them to feel. Wet, wrinkly, and warm all over her body. It really felt like being devoured alive by a vagina, with the added oddity from the hammerspace physics where she felt much tinier inside of the taur woman. And with no signs of reaching the womb just yet.
Ushitora watched the couple with her turned head, feeling her canal get more stuffed without ever appearing heavier to her body. But she could feel all of E'chii'a's movements, touching and pushing her walls. She was no stranger to having visitors in her vagina or uterus, but her tech opened a completely new world of opportunities for her. She loved the familiar, subdued stimuli – and she loved just how much the couple was into it, too. E'chii'a was almost disappearing into her, and hopefully she wouldn't be the last...
The snow leopard kept thrusting into his girlfriend's eager maw even as her shoulders vanished into the slit. Every time he thrust, his dick would disappear down her throat into Ushitora's pocket dimension, but it felt the same as before. He was getting closer to his release, and bucked his hips even faster, hoping to give E'chii'a one last load before she completely vanished inside.
When only her face was still outside, he pushed hard and shouted out, jamming her completely into Ushitora as he ejected ropes of cum down her throat. Throughout his orgasm, he could still feel E'chii'a get pulled deeper and deeper. Her jaws were slowly slipping away from his hyper cock, leaving more of it surrounded by the less smooth walls of the tiger-cow's vagina as time passed.
Until the maw drifted too far, letting go of his spent shaft and leaving him fully hilted to Ushitora. As he recovered his breath, he held onto the taur's hips to look at her rose-hued underside, and there was still no bulge at all.
"W-Woah, fuck... She just...v-vanished!"
The technician gave a friendly giggle, using an arm and front leg to rub the side of her lower half. "She didn't vanish, I can definitely still feel her in there! She just won't make any bulge, since my insides have way more capacity than it looks. Not even your hyper cock should be making any bulges."
"O-Oh, you're right..." He adjusted his hips, definitely feeling her warm folds still enveloping him. "But can you feel me...or her?"
"Mhm! It's like she weighs nothing, but she's definitely in there! Wriggling deeper as she settles in my womb... Pushing her hands against the endometrium... Oh, and I think she's touching herself now!"
"I-Is she? ...Fuck, that's hot~. I wish I was with her..."
"You can join her! Since you're already halfway in," Ushitora joked with a wink, "just push your arms inside as well and I can get you both in my womb."
Staring at her with a blush, the snow leopard moved his gaze down to the slit spread around his entire cock. Ushitora's vagina felt even looser than the mammalian shark's throat, and it really looked like his thick member didn't even stretch her open at all. The big cat did as she suggested, joining his paws together to take the plunge, and they sunk inside along the top of his length.
Her walls throbbed in response, as she let her muscles resume their task of pulling prey deeper to her bovine womb. The tiger-cow's first passenger continue to writhe inside, helping to stimulate her whole body into bringing the feline boyfriend into her company. His arms slipped in with no resistance at all, and his large shaft twitched without any visual indication outside. He continued to willingly feed himself to the pussy, letting the folds coat him in the lubricating juices and drag him in. Ushitora's aroma numbed his mind and intensified his desires, and as his face approached the vulva, he muttered one last sentence:
"Y-Your walls are so hot~..."
The technician moaned as his head slurped right into her. Admittedly, his smaller size relative to E'chii'a didn't make him any less pleasurable to slip inside. She watched her cow belly, half-expecting any disappointing bulges to appear on the sides at any point, but her hammerspace tech worked far too wonderfully as she had imagined. And it didn't affect the workings of her internal bits when it came to swallowing other people. The snow leopard was pulled past his shoulders. She watched as he continued to help himself deeper, until his feet left the ground, leaving the rest of the (literal) heavy lifting to her walls.
The muscles that worked him in alternated drooling out her juices over his fur, and carrying him in with peristalsis. It would be impossible to see the 'funneling' of his body into her vulva, since his remaining bits were blocking the way – but it felt less that he shrunk on his way in, and more like she was much bigger on the inside. With this Manner of technology, either perspective could be right, depending on the reference frame or one's personal opinion.
Ushitora's muscles continued to work the snow leopard in, with his legs sticking out from her hinds – though not for much longer. Her folds eagerly pulled him into its inviting care, slurping the snow leopard's feet into her folds. His body would soon settle inside of her uterus along with the sharkoid alien. Even with the big cat vanishing into her tunnel, her body had already adjusted to the new limit achieved with its artificial modifications. It didn't take much longer to squeeze the second squirming mass through her cervix, joining his girlfriend – but the stirring that she immediately felt between her uterine walls told Ushitora that taking a break and relaxing in these environs wasn't in the couple's plans.
Their arousal only made her realize how much she craved filling her womb, which was nowhere near full. She looked around, and realized that the whole scene had been watched by most other people in the orgy. Not surprising, but still amusing to see all of those gawking eyes, perplexed and aroused by her. The tiger-cow smiled, counting the observers and realizing that she still had a long way to go – before she said what all of them wanted to hear.
"Who wants to be next?"
None of them likely had the same technical savvy as her or E'chii'a, but they could still understand what her mod did on an instinctual level – but more importantly, they also wanted to be a part of that little experiment.
Some of the crowd sitting in the middle of the room got up and moved towards her, away from the largest yellow anthro that Ushitora had noticed earlier. She exchanged glances with him – but the ursine-ish male simply flashed a smile and sat there, stroking his own hyper cock and enjoying the spectacle from the sidelines... He was the biggest person in the orgy, bigger even than Ushitora. She wanted him to be the last.
For now, she focused on the smaller ones approaching her, doing her best to stay friendly without letting her arousal show too much. An average-sized pair of women – a mouse and a human – approached her lower body, with the rodent approaching her udder from behind to fill the outside of her womb, and the purple-haired blonde immediately reaching for her labia with her hands and mouth. The mechanic tucked her four paws and lay on her belly to give them easier reach. At the same time, an 8' skink approached her, with chameleon-like scales which gave a crimson blush to his whole body.
"U-Umm...c-can we make out f-first, m-miss?" His voice was high-pitched and quiet, and certainly the squeakiest that she'd heard from someone his size.
Her head was lower than his from sitting down, and she looked up at the skink with a serene smile. "Of course, sweetie!"
His scales flashed yellow for a moment, as if he hadn't expected her to agree so easily. Even more unexpected was when she initiated the kiss, using her arm to pull him closer and lock lips. The shy reptile kissed her right back, his hue melting into a romantic pink similar to the color that Ushitora had along the front of her body. He closed his eyes, getting deep into the zone as their tongues danced in each other's mouths.
With one clawed hand, he grabbed one of her breasts, squeezing it like the white mouse girl who was groping her udder further below. The skink's other paw guided Ushitora's black-palmed hand to his crotch, as if begging her to give his cocks some attention. The tigrine taur felt them, rather than saw them... And while she knew that some reptiles had multiple penises, there were definitely more than two brushing her fingers – maybe four, no doubt one of the skink's sex mods. As best as she could, she wrapped her hand around the quadruple shafts and began stroking them at the same time, feeling the now-purple lizard's breaths against her maw as he moaned.
She felt the human's cunnilingus reaching deeper into her tunnel, prompting her own tongue to probe into the skink's jaws. The pale-skinned woman must have modified the length of her tongue, reaching far too deep into her folds without having to push her small lips past Ushitora's big labia. The technician felt the long muscle writhing inside, and how her own walls tried to tug it in, but it was far too small and slick to get a grip on. It only tempted Ushitora's womb more, with another patron just out of its grasp...but she'd let the human decide when to push her head in. She wondered if the blonde girl was trying to reach the other two guests, but she could feel them far deeper than the tongue could lick into her.
The human lapped up her sexual juices regardless, forcing her aroused body to produce more, and any excess coated more of the girl's hairless skin. The deep cleaning of the snaky muscle only built up more sexual tension, though she spent that energy pleasing the skink in turn. Her paw felt all four of his dicks throb as she continued to rub them together in a bundle, watching his squamous body turn into a deep indigo similar to her striped fur. Ushitora panted into his maw, and he in hers.
All of the sensations could have been overwhelming, but to her, it was an orgiastic symphony. Her body was the center of attention, inside and out, with so many participants delighting themselves with her body as much as she did her own. Mouth, vagina, breasts, and of course, her womb. Though their movements were deep and distant, the consumed couple was going at it in the tiger-cow's most special spot. She had been limited in how many people could enjoy a lewd respite in her uterus, but her mod would change everything. Ushitora wanted to share the wonders of her body with everyone – starting with this entire orgy.
She was so focused on the naughty action that she failed to notice when the mouse moved away from her udder and underside. The white-furred rodent had sneaked behind of the human girl, after deciding that she wanted some oral action as well. Instead of Ushitora's, she aimed at the smaller vulva on the blonde's crotch, grabbing around the ass to plant her snout there and give it a good lap of her tongue.
The woman jolted forward in surprise, consequently pushing her head into the tiger-cow's vagina that she had been licking so thoroughly. Her face was welcomed in with a wet 'squelch!' of saliva and Ushitora's honey, before being immediately gripped by walls that had wanted to claim the human for so long. She instinctively tried to pull herself out, but the motions were too strong, yet gentle. The woman had no intention of actually escaping, she simply wanted a bit more time outside...
But being unbirthed was inevitable. With her entire head inside, she resigned herself to an earlier thrilling fate, continuing her licks even deeper into the ever-expansive tunnel of folds. But not without giving the mouse her comeuppance. She leaned her hips back, wrapping her thighs around the voluptuous furry chest, to make sure that when she slipped inside, so would the rodent.
The anthro girl at the back didn't mind the triangle hold at all, instead using the better access to the human's labia in order to nuzzle her tongue even deeper. She could hear the muffled moans from the blonde as she vanished further into the hybrid's slit, and feel the pull that dragged her along with the ensnaring legs. Their heights combined like this should've been about 8' in total, but after watching how easily the shark-like alien was taken, the mouse had no doubts that they'd be joining her and the snow leopard very soon.
Ushitora had taken notice of the human sinking into her folds and grappling the mouse in turn. But her body would do its job even without her attention. For now, she simply enjoyed the spontaneous pleasure as her third visitor acclimated to the new surroundings, although her focus was currently on someone else.
She had her hands hugged around the skink's chin, whose cold-blooded cerulean scales pulsed turquoise with each thrust. His neck was bent down, with his pointed-down snout nestled in her cleavage. She used her middle pair of digitigrade paws to stroke his concentric cocks, all four of them quivering for a release that was yet to come.
"Hff...m-miss...!" The reptile whispered and gasped softly between her breasts, getting her naturally sweet fragrance with every inhale. "W-Will your body –mf!– t-take good care of us...?"
"Of course," her voice was as mellow as her scent, "I'll keep you all safe, and all of you can have all the fun in the world while you're in there!"
He humped against her front abs again and again. "Mf...! B-B-But...ahhh...wh-what if you don't feel me...when I'm all small in your womb...? Hng...!"
Her first instinct was to explain that he wasn't really going to turn small inside of her hammerspace womb – but being on the verge of his climax, he likely wasn't interested in a science lesson. Ushitora leaned her face close to his ear and stated the facts.
"When you're as close to me as anyone can wish to be...anything that you do in there, I will feel it. Every. Single. Little. Thing..."
Her digitigrade paws gripped his shafts harder in tandem with his thrusts.
"O-Oh, m-miss...! I-I-I–! Mm-MMMMNNFF...!!"
The skink clenched his jaws hard, pushing his cyan head harder between her breasts, as if they would muffle his awkward shriek. His rods all burst simultaneously, ejecting his reptilian seed as the tigrine paws milked them. The white mess was contained to just the lower half of her anthro-like front-side, splattering along her navel and abs and dribbling down to the self-cleaning floor of Osiris's room.
Ushitora was happy to let the lizard coat her rose midriff with his colorless fluid, knowing that she could find a nanotech towel at arm's reach to wipe herself clean even after some semen had dried on her fur.
"Ahh..." He regained his breath, while his scales took on a dull gray tone as if to preserve his energy. "M-Miss, I have no w-words... It was w-wonderful."
"I'm glad that you enjoyed it too!" She planted a little smooch to his snout, which caused maroon to ripple on his scales from that spot. "Whenever you're ready to join everyone else in my womb, feel free to do so! The girls should be almost done back there..."
She only looked to confirm after she'd said it, trusting that her body would involuntarily ingest more of the two women. The long-tongued human had been fully dragged into her canal's embrace by now, and the mouse's butt was about to disappear into her vulva. Somewhere in Ushitora's folds, the blonde girl still had the rodent's head locked against her own pussy, and from the way that the human girl squirmed, the tiger-cow had a good idea of what was going on in the heat of passion. With her spongy, lascivious, sweet vagina as a backdrop, she'd expected no less. And with the human moaning against the walls, too distracted to continue lapping Ushitora's juices, she imagined that the mouse's tongue must've been working wonders in there...
The hybrid watched the skink circle towards her hind-side as well per her instructions, his scales in a determined orange as he made up his mind to climb in right after the women. She smiled at him and grabbed a towel, using the small intermission to look around the room. With almost half the party inside of her (or on their way), the whole orgy may have appeared to be dying down to any outside observers – when, in truth, it was simply being relocated. There were still others out and about; even so, the place felt emptier than it should. Maybe some people had left because they were too afraid to participate in her experiment...?
As she feared for that conclusion, she locked eyes with the elephant in the room – or rather, the yellow anthro. The large ursoid had been staring at her with an equally large smirk, using some of his four arms to slowly stroke his towering rod. Her eyes followed the motion of his hands down that alien furry log, to its base.
A single glance at his distended ballsack – groped by a pair of his bear-like paws – told her what she needed to know: that Ushitora wasn't the only predator in this group.
***
Khan wasn't concerned at all about the newly-arrived taur stealing his spotlight. It gave him some respite from being the center of attention, while he still enjoyed the company of a few smaller anthros. Having a captivated audience was gratifying, no matter its size.
Although the predominant color of the 12' short-furred ursoid was corn yellow, his entire midriff was covered in a large black blotch. It was mostly hidden behind his foreskinned hyper cock, which hadn't gotten flaccid since the start of the night.
Not that he minded going without breaks, since it made it all the better for his casual partners to enjoy his anatomy. Plus, seeing Ushitora deal so easily with E'chii'a and the snow leopard got him excited... Though he couldn't deny the twinge of jealousy, since it happened moments after the shark-like girl had taken her nice lips away from his member.
With the human girl, the mouse, and the skink all walking away from him – and towards the tiger-cow –, Khan was left with a few stragglers still admiring his cock. Two of his four dark-furred arms cupped the average-sized male anthros against his silky fur, a human and a hamerkop. The couple paid little attention to Ushitora, so the hulking anthro gave them the entertainment that only he could provide.
The technician, he thought to himself, used her mod as an opportunity to mix fun and work – whereas to Khan, having fun was his work, pretty much. He practically lived in Osiris, and he felt at home surrounded by casual admirers, participating in orgies and living off the generosity of other patrons. He'd seen a lot and done a lot, always with the purpose of pleasing his partners. The ursoid prided himself in making fantasies come real, whatever those may be. Though given the public that his large size normally attracted, it meant that he'd usually take on the role of the burly dominant.
And having quite a few mods himself, there was very little that he hadn't tried before. But Ushitora's hammerspace womb was definitely on a completely different level. He secretly shared in E'chii'a's enthusiasm at seeing the technology actually work, although his excitement was less on the science behind it, and more on the possibilities...
With his two free arms, he stroked his genitals. One of his clawed hands moved along the side of his length, which was too thick to completely grip around. Not even the brown hamerkop sitting on the base of his cock, being smooshed against the musky yellow fur, managed to hug his wings around the whole thing. Khan's other paw fondled his nut, the one that the human was so transfixed on.
There were bulges that eventually pushed out of the ursoid's testicles, wriggling and moaning inside. It was another patron in this orgy, who had retired to Khan's private jacuzzi before Ushitora had even arrived...
"She's still having fun in there, isn't she...?" He said quietly to the human, in a low register.
The dark-skinned man didn't look up as he continued to massage Khan's yellow sac, pushing against the squirms and hearing the cum sloshing inside. "Y-Yeah... I thought she would want out by now!"
"Nah. This is the best room in Osiris, heh." The ursoid had plenty of mods to make cock vore as smooth and easy as possible. But even without them, it was well-known that vore itself was safe and pleasurable, and he was used to letting his willing prey sag between his legs. "Besides, she's an axolotl. She must be feeling right at home in that steamy bath~..."
A loud moan reverberated in his nut, causing the man with short curly hair to blush. Khan chuckled before his arm pulled the human closer, smooshing his face against the axolotl's bulge. The large anthro rubbed both him and the bird against his genitals, but he wasn't looking at them. He simply watched the tiger-cow have fun with the skink and two girls, nonchalant as if she hadn't shoved two other people into her womb prior. Thinking about it again was getting him worked up.
"Hmm... You know what, boys? My balls are getting pretty peckish~..." He teased the pair, clenching his muscles to throb his junk and sac underneath them.
The smaller anthros gaped their eyes in surprise, and the human got over his initial shock first. "R-Really?! So you'll let her out now?"
"Not quite. I wanna see if I can stuff all of you in there. Watching her got me in a mood..."
Khan gave a quick glance to Ushitora, before he brought two arms underneath the anthro hamerkop's wings. He wanted some time to work himself up, since it was his first time with more than one average height prey at once. Even if his mods allowed him to stretch out more, he hadn't really considered stuffing more than one person inside of him until now. But the idea of it got its roots deep into his head...
He squeezed the brown-feathered bird along his rod, bobbing him up and down without getting many squirms from the manhandled hamerkop. The spread feathers of his wings continued to hug around the hyper cock, arousing Khan more. His cocktip pointed towards the ceiling, and without E'chii'a's maw to lick it clean anymore, it was leaking some precum. Khan's face was right next to it, and he was tempted to get a taste for it himself, but decided not to. He'd need all the lubrication that he could get for what would come next.
The ursoid's strokes brought the bird closer to the top, until his black bill was half-submerged in the glob of clear, viscous fluid. The hamerkop was slimmer than his throbbing shaft, and he was about as big as the axolotl's – but the bird might prove more difficult to down, since his skin wasn't as smooth or as slippery as hers. Still, he was pretty confident about doing it.
Switching his arms around in order to hold the smaller male, Khan used two hands to tuck his wings back and maintain a strong grip, and the third to nudge that beak into the drooling opening. The entire shaft was covered in corn yellow fur, from base to foreskin, exposing a tiny patch of Khan's ebony flesh at the tip. The black urethra yawned and stretched to receive the head being fed to it, modded in the same way as E'chii'a's throat.
Khan let out a low grunt, feeling the hard bill squeeze deeper inside of him. The brown hamerkop wriggled forward, not trying to break free from the multi-handed grasp, but to help squeeze his entire head inside of Khan. The bear-like alien didn't push the bird too far forward, in order to savor the singular touches as much as possible. He also wanted to mentally prepare himself for the inevitable stretch once the wading bird sunk into his testicles.
"Mmf..." The man with curly hair pushed against Khan's orb, trying to free himself from the musky fur surrounding his vision. He managed to squeeze his face away from the single large hand still on his nape, and looked up at the shaft spilling more pre as it consumed the hamerkop. "Oh w-wow... P-Please, lemme help you push him in!"
"I'm sure I can manage on my own~." Khan teased back. "But make sure to massage me good down there, so I can make room for all of you..."
It wasn't just to seduce the dark-skinned human that Khan suggested it. The ursoid really needed his testes to relax a bit, if they were about to be filled manifold more. The small man still nodded excitedly and opened his arms around the ursoid's nuts, embracing and smooshing the taut skin.
He could feel the turmoil sloshing within – the reserves of cum brewing within, and the axolotl's seemingly interminable libido, soon to be joined by the bird in a private party. And perhaps even by the human himself, if Khan felt like it...! The black man kneaded those seed factories to the best of his abilities, hoping to get the larger anthro as comfortable as possible, that he may have a taste of his fresh seed from inside one of those nuts. As a matter of fact, he hadn't seen the ursine-ish anthro reach his climax at all...
Normally, Khan wasn't ever focused on his own orgasms, being the kind of person who felt much more pleasure by providing it to others. Plus, they tended to get too messy, even for the sex station's standards. But he felt a craving deep down as he discreetly watched Ushitora, one that he hadn't felt often throughout his entire stay in Osiris. Maybe, now that he wasn't the center of attentions, he could indulge himself for his own sake – and play along with those that still wanted to go inside of him.
He pushed against the back of the grabbed bird, feeding him to his cock. The brown feathers turned into a darker textured mess as they soaked in pre, which the tunnel was happy to provide. Khan's pleasure surged from deep in his nut – the organ massaged by the human knowing that it'd be filled soon –, resulting in a throb that slurped the hamerkop with an audible 'squelch!'.
The ursoid grunted again as his walls pulled faster than his hands could push him, dragging the avian anthro into his hyper erection up to his hips. Khan raised the bird feet to line up with his cockslit, not even having to push them in before the muscles dragged them inside.
The hamerkop fully vanished inside of the 7' member, making a large bulge along its underside that inched down through its musky, constricting muscles. The human watched as the other anthro vanished so quickly and easily into Khan, seeing the lump approaching his face as it wormed towards the base of the cock. Though there was no time to admire it, with a set of four arms hurtling towards him and yanking him away from the ursine ballsac.
"Wha– Woah!" He exclaimed as he was surrounded by so many fingers and palms at once.
Khan chuckled. "I didn't forget about you... I'm not gonna keep you waiting~."
The ursoid was the one in a rush – though he didn't want to admit it outright. His lust was getting to him, and he wasn't about to let this sudden urge slip away without being quelled. Khan raised the dark-skinned human well above his head, holding his legs together just above the ankles, and eased the toes right into his black urethra. It was even stretchier now, swallowing the human's feet with ease. The bird slipped down the large anthro's seminal ducts, then in with its bill squeezing into his nuts. His third prey was lagging behind the avian one, which gave him enough space to fill the urethral entrance.
"A-Aahhh...!" The human exclaimed when the multi-armed grip released him – allowing him to sink down to his knees, instead of freeing him. A portion of precum traveled up his body in a 'glorp!', lubricating his smooth skin far more easily than the hamerkop's feathers. "I-I'm sinking so fast... Your c-cock is devouring–ooOOOH...!"
He was interrupted by Khan's tongue pressing against his groins. Due to the flat black muscle being as big as everything else about the ursoid anthro, it covered the human's entire crotch, cupping his entire erection in each lap. Getting to vanish down that powerful shaft after worshiping it all night was too much to grasp, and a few licks to his balls and dick were all it took for him to reach his peak with a slurred moan.
The large yellow male slurped all of his seed, trading fluids and bathing the man's waist in drool before he received a coating of pre when he sunk down more. His clawed fingers loosened their grip against the dark, smooth skin, taking away the only force preventing the human from sliding down his urethra. Once he felt the small cock stop throbbing on his tongue, he completely released the human, moving his face away and admiring how his third prey was whisked away hands-free.
The curly-haired man panted after his release, having his load swallowed down a different path than the rest of his body would be. His flaccid cock slipped into the ursoid's ravenous penis along with his waist. It was too good to wrap his head around, and he couldn't even form any words. He simply stared at Khan's huge black eyes, seeing the alien's lust for him, helplessly watching his face pan away. All the while, his limp body further submerged into the pre-filled tunnel. Each throb gulped more of him like a snake would, working up his chest, and in a few moments, his head. In less than a minute after his orgasm, only his arms were sticking out, but they disappeared inside of the yellow furry tower all the same, down the lewd drain.
Khan panted, each inhale refreshing the smell of the man's cum on his tongue even after he'd swallowed it all. With his normally big balls even larger with a bird and an axolotl inside, it started to feel like he'd made a mistake by also letting the human in. His feet were flat on his fleshy entrance, but the sphincter simply wouldn't budge. The bulge got stuck past the base of his penis, with his sac seemingly not wanting to overindulge along with his cock's sudden bout of voraciousness.
Bringing all of his four paws to his cock, Khan started to massage it, easing his muscles while still trying to force the human the rest of the way in. He was so close, and he didn't want to cum his prey out. He was hoping to keep all three of them tucked in his nuts, sloshing within the viscous pool of seed produced inside. He only needed to squeeze the feet to pass through the sphincter in his vas deferens, and gravity would do the rest. If only he had a hammerspace mod as well, he wouldn't be going through all of this trouble...
With enough kneading and muscle-clenching, he finally felt the fleshy entrance open, and gasped as a single jet of creamy seed flew out of his cock, rushing right past the human. Thankfully, that squirt of cum was the only thing that escaped from his balls, and the human started to slip into the churning chamber as quickly as he'd slipped through the rest of Khan's cock. The ursoid's ducts squeezed the prey into his sac, letting both orbs grow outward again with the new bulges making their way inside. Thanks to some of his mods, there wasn't any barrier between his nuts, and matter could flow freely between the them – although its general shape was still maintained even as the three occupants squirmed about.
Three occupants... It was a lot to take in, literally! His yellow testicles were so large now, splayed across the floor underneath his pre-leaking shaft, churning in a spunky soup of living prey and his pristine reserves of seed. His earlier lust was partially replaced with mild discomfort, having pushed his body to his limit, though it thankfully didn't hurt. His theoretical capacity was even larger, though he wouldn't try getting anywhere close to it without more practice! His body would still be perfectly safe and fine for his prey – and enjoyable, if that enjoyment entailed being submerged in his cum for an extended period of time.
Unable to bring himself to move half of his paws away from his sensitive shaft, Khan only used two to massage his enlarged gonads. Regardless of any discomfort, it still felt nice to be so filled, even if he didn't think of cock vore as much more than a passing interest. Still, his body had craved its allure when he saw Ushitora shoving half of the orgy into her snatch, and now, his urge was wonderfully sated. Plus, the sensations of the trio squirming inside of him were bound to get him worked up – though he wanted to wait for the perfect opportunity to empty his load into the tiger-cow...
As he thought of her, he checked back on her progress. The other human and the mouse were nowhere to be seen, giving him a clear idea of where they were. The skink had turned pink, mimicking the folds that he was pressing his shoulders into. Ushitora was looking around the room, scanning for the other patrons in this orgy. Her facial expressions told him that she was far from sating her hunger – and he smirked, as he'd come to hope as much from her.
The white-striped indigo hybrid locked eyes with him, and he watched her gaze inevitably be drawn to his cock, then his bulging balls. Just on cue, the prey squirmed harder within, making their bulges noticeable in Khan's distended fur. He thought that she'd be jealous, since he'd partaken in some of her potential prey – but her sweet smile told him another story.
Ushitora stood up, taking the skink's legs off the ground, and made her way to Khan with part of the reptile still sticking out of her vulva. All the better for the ursoid, since getting up with the large weight between his crossed legs would've been a hassle for him...
***
The tiger-cow was feeling pretty euphoric with four people in her womb – and a skink on his way. With only his magenta ankles and tail sticking out, she could feel his hips thrusting inside of her. All four of his cocks were hard again, pushing against her soft and sensitive folds. She had to maintain some degree of control over her muscles, otherwise her vagina would've just sucked him in too quickly, but her arousal made it harder. Still, the technician and the reptile both agreed to savor it for as long as possible, in an implicit understanding.
Despite the pleasure and the headcount of her uterine orgy, she still appeared composed from outside. She didn't even have to adjust her gait, which was often the case when she unbirthed people prior to her hammerspace modification. Pacing nonchalantly on four paws, hooves clicking on the floor, Ushitora approached Khan and his inviting smirk, but she couldn't help but wonder if he was gritting his teeth.
"Is everything alright...?" She asked with legitimate concern.
"I'm fine~... I'm just not used to carrying this much weight, is all." The ursoid snickered, giving his squirming sac a few playful pats. He leaned his neck towards her hind-side. "It looks like you're having trouble fitting that last passenger of yours, too."
"Oh, him? It's no trouble at all! I'm just keeping him out of my womb so he can have fun."
To illustrate her point, Ushitora let her muscles work harder around the skink, dragging him the rest of the way inside with a wet 'slurp!'. Her labia, completely drenched in her juices, closed again, and kept the reptile inside of her canal as he was dragged deeper. He was still thrusting as much as he could into her, but from outside, it was impossible to tell what was going on.
Khan crossed a pair of arms. "Heh, that's a pretty nice hammerspace mod you've got there. The name is Khan."
The technician extended one of her black-palmed paws in a greeting. "Ushitora."
"Ushitora, huh... Why does a lovely lady like you have a name befitting a bad omen?"
"Oh, that's just a coincidence. I don't consider myself unlucky or anything!"
He sneered and shook her hand. "Sorry, didn't mean to offend."
"No offense taken. I'm just surprised that you'd know Earth folklore...!"
Ushitora gave a genuine smile, figuring that there was more to the ursoid than met the eye. Khan was quite bigger than her. E'chii'a had been taller than the tiger-cow, but about the same size when taking their different shapes into consideration. Up close, Ushitora could see the black details along his corn yellow body – his flat abs obscured by his enormous cock, his eyes, the outside of his round ears, and a few stripes along his sides. It briefly conjured the image of a bumblebee in her mind's eye.
"You said that you aren't used to being a predator...?" She inquired, pointing at the nuts that churned with muffled sloshes and moans.
Khan suddenly put down his defenses, dropping his dominant performance and speaking at his normal register. "Yeah... Normally, I only have one person in there at a time. But when I saw you earlier, I–" He felt himself getting too flustered, so he cleared his throat and deepened his voice. "...I got in the mood, and wanted to have some of that fun myself."
"You can be yourself around me! I don't judge." Ushitora suggested cheerfully, as she noticed the inner conflict when the ursoid tried to keep up his act. She looked around, spotting only two regular-sized anthro couples still outside either of them. "So, you don't do this often?"
"N-Nah..." He eventually settled on being genuine with the affable hybrid. "Only if another patron asks for it. It still feels nice, of course! But I don't like feeling bloated. Just this once, I wanted to–" Khan paused. "I overheard you talking with that elasmobranch lady, and how you made it yourself. Is it for sale...?"
The tiger-cow was surprised. "Do you mean my hammerspace mod?"
"Yeah. If I had one, I could host an entire orgy in me, with no problem..." His cock throbbed at the thought, letting a bit of spent seed and pre slaver from the entrance. He repeated his question. "Well, is it for sale?"
"Oh! Um... This is just a prototype, I never thought of producing or selling more of this."
The anthro chuckled. "You didn't? I'm sure many people would pay some good money for it. I definitely would!"
"I guess people would... But I still need to collect more data first." Ushitora wasn't concerned in the slightest about marketing her research – she'd only come so far to achieve her scientific aspirations.
"Collect more data...? Heh, I can help with that~."
Khan slowly got up, trying to keep his balance with the heavy swing between his legs. He could feel the occupants twist and stir in the rocking batter bath, pushing that boundary of discomfort and pleasure with each jostle. Two of his paws had to cup around it while he got used to the weight, with a third one idly stroking his large shaft.
"HEY, EVERYONE!" He shouted in a low pitch, calling the remaining patrons while he pointed at the indigo taur. "This whole orgy is being relocated to this lovely lady's womb. Got it?!"
Khan's commanding persona was as effective as he'd hoped, with the other anthros immediately stopping in their tracks to turn around and approach them. Ushitora, however, wasn't really a fan of his method, even if it did expedite the part where she had to convince each of the other customers of Osiris to climb into her. In some way, being 'the new location of the orgy' felt a bit objectifying, even if it was still what she wanted...
"Uh, sorry, Ushitora." Khan whispered in an apologetic tone, realizing that she appeared distraught after his call-out. "I was just trying to help..."
She shrugged at him, figuring that it wasn't worth it getting upset by the ursoid's accidental rudeness. The tiger-cow turned with a welcoming smile to the remaining anthros, of which there were three – all of them seemed dazed, as if awakening from a long trance. As a matter of fact, Ushitora hadn't seen them near Khan earlier – by now, his whole entourage was squirming in his tight testicles or her spacious womb.
"Relocated to this lady's room, you said...?" The question came from an anthro dog – a Kokoni, with her long golden fur and floppy ears. She had her arms wrapped around her midriff, from where a muffled 'shlick!' noise could be heard occasionally.
"Not my room, my womb!" The technician giggled warmly after correcting her. "And only if you want. It may not seem like it, but I have five people in there, and there's enough room for all three of you too!"
"All three...?" The canine groggily looked at the other anthros of her size, a rabbit and an owl. "But...what about him? Is there also room for him in your womb...?"
She looked down and unveiled a smaller head against her torso, belonging to a 2 and a half foot alien. He had downward ears half as long as his violet body, and an azure mane along his spine and his long tail. His shape vaguely resembled that of a lizard, but his skin was smooth with no scales. The small anthro didn't even look up after the Kokoni uncovered his head, and he simply continued to grip her fur with his small hands and thrust his hips.
Ushitora hadn't noticed him until now, but immediately recognized him as an unqeksi. The males of its species had unique prehensile cocks, longer than the rest of their body when fully extended – and surely enough, underneath the dog's fluff, there was a visibly writhing mass that looked more like a tentacle.
"Oh! I hadn't even noticed him. But of course, there is also room for him!" The tiger-cow exclaimed. It seemed like a silly question, but nonetheless, she answered it soberly.
The spaced-out dog sighed in relief. "...Good. He's knotted to me and pretty deep in my womb, and I don't feel like pulling him out..."
Ushitora chuckled – it was funny that this was the Kokoni's only concern. "You two will have enough room to continue your fun inside... If you let me unbirth you, of course!"
"Yeah, sure... Sounds nice. Just sit on us, or whatever..."
The indifferent canine simply cupped the unqeksi's head against her belly once again, keeping it where it had been for the last several hours. The slim reptile-like alien had seemingly endless stamina, probing all around her womb with his self-lubricating cock. The tip would occasionally slip out through the Kokoni's stretched cervix, before infiltrating it again with an audible 'shlick!'. Thankfully, his sexual fluids had analgesic properties, and she felt no pain from its excessive but harmless exploration, only a lingering high. As long as her little mate was still providing her with that fuzzy euphoria, she didn't mind ending up inside of Ushitora with the rest of the orgy.
The unqeksi, however, was evidently too lost in bliss with such a lenient partner. With his legs and tail limp underneath, and locked in a long coitus with the canine, he couldn't care less about the world as he clung to her fluff.
The hybrid wasted no time following the dog's request. She turned around, giving the Kokoni a good view of the back of her udder and her soaking wet vulva, before the latter descended onto her head. Ushitora had done this before with large toys and other people, and knew how to swerve her hips to provide a smooth experience. But her hammerspace mod made it even easier to slip the dog and her little partner inside, with no resistance whatsoever. In record time, her labia kissed the ground, splattering it with the juices that her new guests had dislodged on their way in.
She clenched and raised her hindlegs, leaving behind only a puddle of squirt where the canine had been standing. But Ushitora could still feel them going deeper: her fur brushing her folds, her arms hugging tight around the unqeksi on her midriff, and even her tongue giving discreet licks to sample her juices. The taur suspected that the Kokoni would likely get a taste of the skink's cum in its midst – who could still be made out along with everyone else in her physics-defying uterus.
Ushitora expected her trick to amaze the two remaining anthros, as well as Khan, but the lagomorph and the owl were transfixed on him and his bulging yellow sac, wobbling between his legs. The ursoid gave her an apologetic smile for taking her spotlight right back.
"S-Sorry..." He said without forcing a bassy voice. "They told me that they were too shy to approach me earlier, what with everyone else around me."
"Oh...?" The taur looked at each of the shy anthros, who seemed even more nervous to be surrounded by a pair of much larger people. They must have really wanted to have fun with Khan to build up the courage to ask him. "Well, he's all yours now, sweeties! And you'll get to spend some good, long, quality time with him now."
"B-But how, if you said that we're going into your womb?" The white rabbit asked, gaping her confused red eyes.
"That's easy! This 'lovely gentleman' is going in right after you. Isn't that right, Khan?"
The ursoid was surprised by her outright saying it. "O-Oh...uhhh, y-yeah! I-If it's no trouble fitting me in, that is..."
Ushitora smiled provokingly. "Oh, please! You'll be no harder to get inside than the unqeksi was."
Khan blushed at her piercing taunt, not expecting the sudden change in attitude. Then it hit him that she was getting back at him for his rude call-out earlier, and the realization flustered him even more.
"A-Anyway...!" He cleared his throat. "Let me help push you both in before me. We don't wanna keep the...lovely lady...waiting, do we?"
"A-A-Actually, m-mister Khan..." The spectacled owl hooted with a heavy stutter. "We were h-hoping that we could join the other people in y-y-your...y-you know."
"...In my balls?!"
"Yeah. Th-They s-seem to be having f-fun..."
"So much fun!" The rabbit pitched in with a wishful tone.
Khan scratched his forehead with the only hand not cupping his threshing yellow orbs. "Sorry to disappoint, but I'm just not used to having so many people in there... I can't fit anyone else."
The large-eared mammal couldn't help but stomp her foot. "Aw, man! So we're too late to go down your cock...?"
An idea suddenly flashed in the ursoid's mind at the rabbit's outcry. He looked at both of them with a smirk.
"Hey, I never said you two /wouldn't/ go down my cock~..."
Suddenly, his four large paws all lunged forward towards the pair. Even Ushitora was surprised at how quickly he grabbed and smooshed the two anthros together, displaying complete mastery over his multiple upper limbs. He raised the hugged pair and flipped them upside-down, bringing the black feathers and white ears of the owl and rabbit, respectively, closer to his furry rod.
Simultaneously, he plunged both of their heads inside of his cockslit. Together, the average-sized anthros were about as thick as his shaft at their shoulders, and they'd likely push the elasticity of his vore mod to its limit. He'd never tried his hands at multiple prey at once before, nor with anyone larger than average height, but Khan wanted to impress the tiger-cow more than anything. In terms of the better predator, he was obviously far behind in second place – but he still wanted to narrow that margin.
The prideful ursoid grunted when he felt a throb in the pit of his urethra. His sac clenched around the cum-laden guests as a surge made its way up, expanding his tip to swallow more of the pair. All of the excess lubrication in his tunnel helped too, soaking their bodies to help them slip down. The owl and the rabbit were bundled together tightly, slowly sinking down as a single large bulge in the underside of his cock's yellow fur. But Khan could still squeeze them more with the help of his strong clawed hands, like forcefully feeding a hungry and meaty pipe.
Each time that the urethral walls yielded, and the duo sank further, Khan moaned. It was unavoidable, given how sensitive his stretched walls were. Despite his body letting his two 'cock snacks' sink down to their waists, he could feel his balls churn in discontentment, loathing having to carry any more than the multiple prey and its batter. Thankfully, with Khan's plan, that wouldn't come to pass.
"Do you need any help...?" Ushitora offered, even if it seemed that the ursoid had a fourfold grasp on the situation.
There wasn't much for her to do but watch, though she was eager to find out what his plan was. She didn't have to wait any longer, as a blushing Khan looked down at her through the two pairs of legs sticking out of his dick.
"T-Turn around, quick. I wanna cum them into you before they slip too far in~..."
His balls sloshed when the three trapped occupants inside lurched, getting more active when Khan's testicular wrinkles pressed down on them from his arousal. The taur wondered if this had all been an elaborate excuse to get his built-up seed into her. But with her own guests squirming wildly in her womb orgy – which only got herself more worked up –, Ushitora figured that she'd like that, too.
"Of course, Khan," and she turned around. The technician pointed her hind-side towards him, showing no signs of the Kokoni that she'd just swallowed. "Whenever you're ready!"
The ursoid could feel the preyish pair squirming deeper in his cock, to the point that there wasn't much to grasp from outside, only the bird of prey's talons and the lagomorph's ankles. Even though they weren't fully in, he was confident that the smaller anthros weren't slipping too far forward from their current spot, and likely satisfied with their immersive yet short trip down his ebony urethra.
"I'm ready."
Khan pushed his cock down, using all of his hands to direct the tip of his weighty shaft. The feet sticking out from his foreskin actually helped him aim the monstrous meat towards Ushitora's pussy. He was careful not to bump her hinds or udder, and slowly eased it inside.
He shouldn't have been surprised to meet little to no resistance, but even then, he never would've expected to penetrate a smaller taur so easily otherwise...! It was as if her firm vulva was completely loose, its lips spreading like drapes around his length. Similarly, the walls of her canal enveloped his cock, without any signs of forceful stretching to accommodate it. Khan continued to ease it in, hearing her moans as he reached deep into her without so much as making a bulge outside. He clenched and gasped, feeling his cockslit close around the feet, letting his tip brush against her folds without anything in the way.
Ushitora could still feel the increasing weight of his throbbing penis – especially from carrying some extra mass in his urethra –, but it was hardly unbearable. She felt Khan's hands grabbing around her bovine ribs, steadying himself to shove the rest of his bulged-out shaft in. As his hips touched her hinds, it fully vanished into her canal, without even reaching her filled womb. Her walls tried to pull it in like any other visitor, but she she didn't force her muscles too much around it. The tiger-cow only wanted to help him accomplish his plan, not to slurp his whole body in too soon.
As the ursoid began some subdued thrusts in and out of the hybrid, he felt a shift in his groins that made him tense up. The two anthros were slipping deeper into him instead of her, with their knot-like bulge worming out from her labia and through the base of his cock, into his body proper. The owl and the rabbit were being pulled towards his balls, which wasn't his plan at all...!
He tried to clench his muscles and stop their entry, which only made it worse. The trio in his testicles squirmed more acutely, and the increase in arousal caused his cock prey to slip further away from the entrance. He was getting more and more nervous, since there was no way that his testicles would be able to handle any more guests.
"It's okay, Khan..." Ushitora broke his uneasy concentration. She was able to deduce why he was nervous, from feeling the bulging masses shifting out from her own body, as well as the increasing stiffness from his limbs. "Take a deep breath, relax, and focus on my walls around you. You can do it."
Khan was stunned for a moment, but being the least experienced predator, he did as she instructed. Despite the pair wriggling ever deeper into him, he tried to put his fears aside, continuing his thrusts as best as he could. He cleared his intrusive thoughts, leaving only his original plan at the forefront of his mind.
He felt a twinge of despair when there was a familiar pressure right against the entrance to his sac from the vas deferens, with two faces nudged right against it. Thankfully, the sphincter was shut tight, and they didn't slip through. It was just like when the human was the last to push into his testicles. Or was it the hamerkop who was last...? The details from early were fuzzy, he'd been too focused on getting both of them in there.
Instead of remembering, he was focused on blowing his load into the tiger-cow. As luck would have it, the pressure being built-up by his living sounding rods wasn't insurmountable, and was only getting him more and more aroused unlike ever before. He thrust his cock harder into her hammerspace pocket, feeling the weight of his prey partially inside of his prostate, bulging out the base of his cock. His release was fast approaching, a looming torrent – no, an avalanche...
His four hands pulled Ushitora towards him, and his hips pressed hard against her drenched backside. And he roared.
"RAAAA-AHWWWHHHRR!!"
The floodgates were open, and the walls of his testicles clenched hard to juice them for all of his jizz reserve. What felt like his thickest load ever quickly traveled through his ducts, a noticeable weight that was being spewed upwards, bloating his concealed cock from the base up. Despite everything, a part of Khan still expected that Ushitora's body would swell with his seed, although he could feel it splatter against her walls, then back at his skin, as he felt himself getting drained.
The tiger-cow also felt the liquid and solid parts of his ejaculation traveling through the ursoid's length, before they'd even exited through his cockslit. Without her hammerspace mod, his sizable splooge would certainly have distended her belly as it sloshed inside of her sensitive folds. But the pumping liquid dispersed along the tunnel, leaving its mark on her vagina without outright flooding it. She'd felt a couple of wriggling masses get launched deep, and her body dutifully guided the ejected anthros towards her womb, that the shy couple may get better acquainted with the rest of the party.
"Hff...h-holy shit..." Khan's cock was still nestled deep into her vagina, enjoying the idle tugs of her walls that confused his length for another patron. With the final squirts exiting his shaft, he also had to wait for his clenched nuts to relax in order to fully collect himself. "That was intense~..."
Ushitora giggled. "Yes! Definitely more intense than I had expected tonight to go. You did well, Khan!"
"Th-Thanks..." He blushed a bit at her words, which sounded like genuine encouragement. "Uh, so...did my plan work?"
"It definitely did! I can feel the rabbit and the owl hugging each other, and they're just slipping through my cervix to join everyone else."
"I-Is that so..."
He carefully stepped backwards to pull out. His hyper cock slipped out just as easily as it did on its way in, seemingly emerging out of nowhere. It was flaccid for the first time tonight – though not any smaller –, and very little of his seed came out when his cock head slunk free from her vulva. Even after all of that, Ushitora and her vagina were unabashed.
Khan rubbed his sagging nuts, which still felt heavy with the weight of his three occupants trapped within for longer. Although his sac no longer sloshed with his batter, they seemed worn down after enduring his oppressive orgasm – but still squirmed and moaned lethargically inside of him, indicating that they were perfectly fine.
"Heh, they're still in there. Maybe this predator thing isn't so bad... But I'm still envious."
"Envious of my hammerspace womb?"
"Yeah..." Khan admitted. "I would give anything to have a whole orgy in my nuts, you know."
Ushitora giggled. She could definitely relate to the bottomless urge that not even a threesome in his balls could fulfill. "Does that mean you don't want to go inside of me anymore? You don't have to, if you don't want."
He sneered. "When I said the whole orgy was being relocated, I meant it. I'm a man of my word~... Besides! It's not every night someone smaller than me gets to do something like this in Osiris. No way I'm passing on a once-in-a-lifetime opportunity!"
Once again, the technician beamed warmly. "I'm glad! I was hoping you'd want it, too. Are you ready, then?"
He shook his head. "Not yet. I have one request."
"Oh? And that is...?"
"Lie down on your back."
"...Is that all?"
The tall yellow anthro nodded. "You didn't really get to enjoy watching anyone disappear into you, have you? You were too busy making sure that they were all comfortable and having fun. Well... I wanna amend that, and make sure you have fun, too~."
The indigo hybrid seemed surprised by the reasons behind his request, but Khan's wishes were genuine. Despite their differences, he felt that the fellow predator was a kindred spirit. Wanting to please others before themselves... And thanks to her, he'd had experienced pleasure unlike any before. Now, it was just the two of them – for the most part. But not for long, as she'd soon get her last voluntary subject to join her experiment.
As Ushitora turned around and lay on her back, the floor deformed, becoming cushy under her weight. This was another feature of the rooms in Osiris, with the material that made up the floor adjusting to the sudden shifts in pressure from their patrons. Anywhere could be a mattress once you'd learned the proper way of lying down. Ushitora wondered if its inventors had intended the material to serve this purpose, and if her own tech would eventually find a use that she couldn't ever predict...
Her rosy ventral side was exposed, a pose that she wasn't used to assuming even when alone. The tigrine upper body was almost upright, using her front legs to prop herself up. Her hoofed feet were spread in the air, but her vagina was partially covered underneath her pink udder in this position. With her tail to the side, there was more than enough space for Khan to squeeze himself in as she watched.
The ursoid sat down next to her far side, sighing in relief as the weight between his legs eased once his sac was laid on the ground. With his cock no longer erect in front of him, Ushitora could clearly see his dark-furred belly again. His yellow hands moved to her udder, pushing the squishy cushions forward onto her flat bovine tummy. Then, he brought his legs closer to her revealed lips. Khan looked up at her, wondering if he should ask for permission again, but the atmosphere between the two couldn't have made it clearer.
He brought his two feet together and pushed them into her seemingly limitless folds, watching as they effortlessly entered the smaller tunnel. In no time, her peristalsis started pulling him in – but he still helped his legs together into her, even if it felt unnecessary. Khan used a pair of hands to pull his sac over his own thighs, letting him join them closer. The solid sloshes of the anthros inside provided a weird sensation, and the creeping heat was hardening his hyper cock once again.
"Th-There we go, on our way to get lost inside of you. Just like the others..." He patted the distended furry nuts, to explicitly include his own guests in the collective pronoun.
Her walls tugged on his ankles, and he had to scoot his butt closer to avoid sliding against the ground. It kind of looked like his body shrunk and funneled right before her labia, even if it didn't feel any different!
"You won't get lost!" She replied, locking eyes with him after he adjusted. "You'll all be in my womb while I collect the data I need."
Ushitora watched as the larger anthro's legs continued to vanish into her, barely stretching her vaginal canal. She could still feel Khan's feet shifting inside against the tug of her folds, but his bigger size didn't impact much. Her walls didn't stretch at all in order to fit him in, and he was being pulled faster into the seemingly small opening. It was amusing to watch the ursoid slowly vanish without making any bulge in her, she had to admit.
When he was knee-deep, the technician wasn't concerned about those filled balls of his. They appeared much less rounder – after all of his seed had been pumped into her body –, but quite big with the occupants still smooshed within. He shivered at the touch of their yellow furry exterior to her warm folds, sinking into her along with his thighs. Her walls added some minute pressure to his orbs, allowing her to feel the shifts of their shared prey as well.
Khan fidgeted forward a bit, before his butt eventually got lifted off the ground. "So, you have no plans of letting us out...?"
"I intend to let you out, it will just take a while! And in the meantime, you'll get to enjoy yourselves, all comfortable and horny inside of me, with plenty of space for everyone."
His expression changed a bit, and Ushitora couldn't get a good read on him. Maybe he wasn't so sure anymore? It wasn't her intention to deceive him, or anyone for that matter. The inward contractions suddenly stopped, and she asked apprehensively.
"...Is something wrong? Getting cold feet? Perhaps, you still think of me as a bad omen...?"
"Hey, I never really thought you were one...! If anything, I'm pretty sure that an unlucky name wards off any bad fortune...o-or something like that."
The ursoid brought his lower pair of hands down to her vulva, spreading them wider to squeeze his crotch in. Ushitora shivered with a quiet moan as Khan made his willingness abundantly clear, lifting himself off the ground as he sat his butt on the floor of her tunnel instead. With his fingers spreading her entrance, he got a glimpse inside of her pink folds – it really looked like she was much bigger from the inside, perhaps more than the whole room they were in...! His balls were fully inside of her by now, and his stiff cock was pinned between his torso and her soft udder, pinched at the base as it was swallowed. The muscles were slowly forcing his body into a horizontal position, making short work of his waist.
"B-Besides," Khan continued, "if it really is as good in there as you say, it hardly sounds like a bad deal! I don't mind if I get to experience this womb orgy for a long time~."
The tiger-cow smiled. "Excellent! And my hammerspace tech is perfectly safe, but I need to conduct this test to figure out the limits of the mod's anti-relativistic effect, before other people can start using it."
"Is that so...?"
"Of course! It IS perfectly safe...but there could be imperfections or kinks with a sufficiently large amount of prey, and I need to make that clear for other users. I wouldn't be at peace with myself if I put others at needless risks due to negligence. It's all for the sake of science!"
"Science? Heh, sure...if you say so~."
Her vagina continued to swallow him as they spoke. Most of his body was massaged by flesh and covered in fluids, mainly her juices and his spent seed. He was chest-deep in her, with just the head of his hyper penis poking out from her pussy. Khan watched the yawning cockslit staring back at him as it slowly squished into her body's hot embrace. He imagined that, one day, it would be a whole orgy slipping down into him, instead.
"Hff... In that case, I better give you as much 'data' as I can while I'm in here~."
Khan leaned his neck forward, smooshing his snout against her udder to make out with one of the pink nipples – the best that he could reach for, given that her clitoris was outside of his reach behind his back. At the same time, he started to thrust into her all-encompassing walls, getting more acquainted with his new 'lodgings'. Ushitora cooed quietly to herself at the attention she was receiving, and the taur appeared simultaneously bigger and smaller than him – a weird feeling that he admittedly loved. Maybe it was her fragrance that was instigating this arousal on him, but he couldn't deny how hot this whole situation was.
He squeezed his last pair of arms into her, leaving only his shoulders outside. They looked funny squeezing into her velvety entrance, since they were as wide as her entire hind-side in a normal situation. He'd noticed how the technician didn't really moan much, but her lower lips continued to squirt more and more lube onto his neck and nape, making her own cravings obvious.
Even so, her body never stopped pulling him in. If anything, Khan's efforts only made her greedier for him. As moments passed, it was harder for him to keep his lips around her bovine teat. Another tug yanked his face down, leaving behind a strand of saliva that broke as her small labia cinched around his jaw. Only his face was outside of her – soon enough, there wouldn't be a single sign of where he was staying.
"Oh...seems like we're running out of time." He struggled to speak, with her folds squeezing her chin.
Ushitora chuckled, no longer able to see his head behind her own drool-drenched udder. "Not at all, sweetie. We're just getting started!"
Her words reverberated around his round ears, sinking into her in these final moments in the outside world. He wanted them to last for much longer – but it wouldn't do to keep the lovely lady waiting.
"Heh, you're not wrong~... Pleasure meeting you, Ushitora. I only hope that you keep this orgy going for as long as possible."
"The pleasure is mine, Khan – and I hope that you do the same in there."
Her slit closed before she even finished speaking, letting out another clear squirt as the massive ursoid finally was consumed. Like everyone else in this orgy, he was carried ever deeper through her wet folds. Due to the nature of hammerspace, she couldn't pinpoint his location from outside, but she could definitely feel her walls conforming around him as he was pulled deeper.
Almost weightless, he was quickly dragged through her welcoming cervix, deposited along the uterine chamber, tucked steadily in her safest spot. Ushitora was curious to know how the chamber must've looked and felt from inside, with her mod in place. Of course, she could check her research data for answers, but nothing would beat Khan's – and everyone else's – first-hand testimony once she would eventually let them go.
Being reminded of her goal, she checked her bracelet while still lying on her back. The holographic projection of her compiled data appeared when the device detected her face. Her eyes darted through the multiple sensors being displayed, making sure that the numbers matched her calculations. All parameters were in the expected range.
"Not a single blip...!" She smiled in satisfaction, patting her flat lower belly with one of her middle paws.
***
Being in deep space, it was always nighttime in Osiris. With the many pleasures that one might find in what was dubbed the 'haven of endless vices', it was easy to lose track of time. It wasn't the place for those that overvalued the only finite resource in the galaxy. Of course, any patron of the sex station would disagree that any time in here was wasted – and Ushitora was of the same mind.
Regardless, the technician was well-aware that it was much later when she eventually left the quiet room. She'd taken the time to wipe off all of the multiple fluids on her fur and udder with the towels provided in the facility – as well as enjoy the contradictory sensations of simultaneous fullness and emptiness. She'd never had so many prey at once before – a baker's dozen, if she wasn't mistaken.
Ushitora felt all of them inside of her, some more clearly than others, squirming and grinding against her womb and each other in unimaginable positions. She couldn't hear any moans or squelches, but she didn't doubt that her uterus was the stage for an extraordinary, overwhelming orgy. Khan may have been envious of her and her hammerspace mod, but she was also envious of him, in that she wouldn't learn so soon what it was to actually experience it from the other end.
She stretched her indigo arms above her head, yawned, and looked around, nobody the wiser to the party being transported inside of her. But of course, the hybrid wasn't about to call it a day and return home. Her research wouldn't be over until she could establish just how much stress her technology could withstand. Besides, she still felt incredibly empty inside. Her vaginal canal yearned for more people to cross its fleshy passageway. It would be remiss of her to head back without definite results.
Making her way on dark hooves and digitigrade paws, Ushitora walked down the hallway, to the orgy next door. She beamed to herself, wondering how many people it would even take to get the data she needed, and walked through its automatic door.
