An Unconventional Endurance Test

''Haah... why are they always out of croissants...?''

A melodramatic sigh arose from a young man as he meandered down a rainy street, the pitter-patter of the falling water made more audible as it bounced off of his umbrella. Few were out in such weather, the afternoon sky darkened to a greyish hue and leaving the city rather drab... though, at that moment, the young man was more bothered by the lack of fancy bread at the shops than the weather itself.

The young man in question went by the name of Louis; hair a dark brown and with a sharp jawline, his mocha eyes glancing idly down at the plastic bag in his right hand, making sure it didn't rip and spill its contents all across the pavement. His footsteps carried him along said pavement towards a tall apartment building; the concrete structure a touch gloomy in the greyish afternoon light, but with a rustic sort of beauty to it. He certainly didn't mind it. Shelving that thought he gladly stepped under the overhanging entryway, the chilly wind abating and the pouring rain ceasing as he hurriedly stepped into the building itself.

''Hah...'' Rolling his shoulders a little Louis made his way up the steps; his boots making each step echo up the stairs.

Living in this section of the city could be tough at times, admittedly. Various supernatural species made their home here, whether they be simple residents also owning apartments and homes or more sinister folk who hid in alleyways and feasted upon unsuspecting humans. Thus he was always a tad wary, having run into said supernatural species more than a few times... though, at the same time, he had enough experience with them to know they weren't much different than humans in that respect. Some good, some bad, some in-between.

And one in particular was most certainly the exception to the norm.

One who Louis laid sight on as he reached his floor and unlocked his door, opening it to reveal not just his living room – but the woman sat upon the cream couch in it.

Omega Alpha.

Standing on the taller end of the spectrum, Omega struck quite the eye-catching figure with her long pale-rainbow hair, her eyes themselves red yet with an ever-changing hue to them. The white bodysuit she wore was snug and form-fitting, highlighting her slim frame and long legs. She usually wore a cloak over it but for once had abandoned it, sat with her knees up to her chest as she gazed down at her phone, watching a video of some kind; the position giving him a chance to admire her left arm. It was a prosthetic; at least, a prosthetic of some kind, the golden design across the biceps never failing to draw his eye.

Truthfully, Omega wasn't a woman at all – technically being an androgynous entity closer to a god than your average supernatural being. However, according to her, she could simply change gender as desired... and, since he was the first person she came across when she stepped out into the mortal world, and he assumed she was a woman, she henceforth referred to herself as one. He saw no reason to say otherwise.

''I'm back.'' Louis called out lightly, shutting the door behind him and locking it.

''Welcome back.'' Omega greeted in her ever-present monotone. ''The shop did not have any of those 'croissant' breads, did they?''

''How'd you guess?''

''I sensed it.'' Was her vague answer.

''Then why didn't you just tell me that before I left?'' The young man sighed exasperatedly.

Omega tilted her head back, looking at him with those piercing eyes of hers. ''I thought it unwise to crush your hope. At least by adventuring to the store, you retained that hope for a little longer. Perhaps it would motivate you, perhaps not. I merely saw no reason to extinguish said hope unnecessarily.''

''Right.'' He flatly responded.

Omega's speech pattern could be a bit... tricky, at times, to get used to, but he didn't mind it too much. Not least because she was attractive and, to some degree, completely oblivious to human etiquette.

It was practically a pervert's wet dream. A beautiful woman who was completely unaware of how humans behaved, and had no sense of modesty? More than once he had been tempted by the thought of convincing her to strip, truthfully, but he always resisted the temptation if only so he himself wouldn't become a pervert; telling himself he was better than that. Though that did little to stop him thinking of Omega when he was alone in his bed at night.

Hastily banishing the thought Louis made his way into the adjoined kitchen, taking out the couple jugs of milk and other foods he'd picked up and putting them away. His kitchen wasn't the biggest nor was his apartment overall, but it was big enough for the two of them at least; Omega herself taking the guest room. He didn't mind hosting the quasi-deity; she wasn't from their world and he didn't like the idea of leaving her out in the world by herself lest she be manipulated, or get the wrong image of mankind and decide to go full genocide-route on them. Thus, he let her stay with him and learn about the mortal world at her own pace.

Though of course with the internet involved, things sometimes became... complicated.

Something that Louis was reminded of as he walked out from the kitchen and approached Omega, leaning on the back of the couch. ''What are you looking at?''

''Another strange 'challenge' both mortals and supernatural alike are partaking in.'' The enigmatic deity stated, holding her phone – one of his old ones, technically – up, showing a video playing. ''I am curious as to its purpose.''

The young man blinked once, twice – and then blushed as the connected the dots in his mind. Laid on the phone screen was a rather attractive Succubus girl smirking seductively at the camera with her arms folded just under her chin, her ass up in the air and her back arched to borderline-impossible levels, her legs out on either side to support herself. The video then cut several seconds later to another person, a regular human woman, trying to replicate it with obvious difficulty; giving up when her back made a wince-inducing pop, the short scream the woman made telling she might well have dislocated something trying to do it.

''Supernaturals seem to be having an easier time with this 'Jack-O Challenge'.'' Omega observed idly. ''Though I then cannot fathom why they would try to replicate it regardless. Pride, perhaps?''

''Erm...'' Louis rubbed the back of his neck, unsure of how to explain. ''Entertainment, I guess. It's like fail compilations; they're for people's amusement.''

''I see.'' Omega noted with a hum. ''I am interested in attempting that myself then, for my own 'amusement'.''

''It's quite hard, you know.'' He joked a little. ''I'd rather you not break your back trying.''

''Nonsense.'' Though Omega wasn't competitive, the slight fire he caught in her eyes told him that she intended to prove herself.

A fact proven when she abandoned her phone; laying it down on the couch next to her and rising up to her full height, making her way over to the open space of floor between the TV and the cream couch. Then before Louis could so much as utter a syllable Omega bent over at the waist, her tight-fitting bodysuit giving him a good look at her defined ass. Shifting her heeled feet across the smooth brown floor more Omega widened her stance; planting her hands down on the floor until she could ease herself down onto it, carefully crossing her arms in front of herself and resting her chin nearly upon them; her back arched in ways that would probably cause significant pain to regular humans, yet she seemed completely unphased.

''Hmph.'' Though her tone remained monotone, a slight tinge of smugness seemed to colour it. ''See. It is nonsensical to believe I am incapable of doing it, if mere demons are capable.''

''Uh... yeah.'' With her unable to look at him he took the chance to admire her ass, his heartbeat quick in his chest – before his dick did the talking for him. ''I heard it's harder though to maintain it for long periods of time.''

''Logical. Though simple for me to do.'' Omega simply stated, remaining in her position easily – her arched back not shifting even once.

Louis swallowed, approaching behind Omega. Previously-smothered lewd thoughts came surging up to the surface in a wave, suddenly, acutely becoming aware of the opportunity he had in front of him. His better side tried to push them back down but utterly failed when he had Omega literally bent over in front of him, her ass seeming so smooth within her full-length bodysuit that he was almost tempted to outright grab it, if only just to fuel the lewd thoughts he had of her at night. She probably wouldn't even consider him a pervert for it; lacking much in the way of modesty or embarrassment, if she could even feel such emotions in the first place.

Thus he quickly succumbed to his lewder side, and decided to take advantage of the sudden situation he found himself in – seeing how far he could push Omega. ''Well if you're so sure... why don't I try and test that?''

Without giving Omega time to question his hands held her hips, sliding down – before he tickled her ribs.

…

''...I am not ticklish, Louis.'' Omega flatly said.

''Ah, right...'' Bashfully his hands retreated back to her waist. ''Then... what about this?''

With only a moment of hesitation he grabbed her ass. It felt as soft as he thought it might, her clothes sleek and form-fitting to her rear, allowing him to feel the soft flesh beneath. A leotard-like section was thicker than the parts around her legs or ass, encouraging him to grope her butt and slide his hands down to her thighs, squeezing them too. Omega didn't think anything of it, merely humming and easily maintaining the position. Thus, Louis decided to get a bit bolder – sliding a hand around and cupping her crotch.

Omega said nothing, her fingers tapping patiently, as if expecting more of a challenge. Carefully controlling the eagerness within himself Louis stroked her clothed sex, pressing his fingers against her silky clothes and rubbing circles upon where her pussy would be – briefly wondering if she had bothered to 'add' that part to herself. Deciding to see for himself the young man knelt down behind her, getting a eye-full of her ass, before grasping her skin-tight clothing and pulling at the crotch seam on both sides. It strained, made a rip – and then he tore a hole in it.

And revealing Omega both wore no underwear, and yes, had a pussy.

''Hm?'' Omega's curious voice drew his attention. ''Was there a purpose to that?''

''Testing if you can hold that position.'' He quickly stated, groping her thighs again – eyeing her bare slit lustfully. ''I won't push you over or anything, but I want to see if you could uh... resist some... stimulation.''

''I see.'' Omega accepted that response, offering no further protest.

Eagerly the young man slid his hands up, groping her ass once more before moving his right hand to her pussy, running his fingers along her folds. She was smooth and felt soft, tempting him to slid his index finger into her entrance – intimately feeling her hot walls clamp down around his intruding digit. He slipped his middle finger in with it, wiggling the two of them around as best he could, exploring more than he did finger her. His experience in the past with women was limited, and he was eager to 'experiment' a little to make up for that.

Tilting his hand slightly Louis began to pump his twin digits into her again, rubbing her hot walls with his fingertips and feeling them press down on his digits. Omega made a little sound of curiosity but didn't protest, encouraging him to work his fingers more, pumping them back-and-forth. The young man relished the lewd feeling of her walls pressing down on them, tilting his head slightly and looking at her pussy from different angles as his fingers pumped into her, adding a third finger and thrusting it in deeper – raising his hand and angling it slightly, pushing in up to the knuckle.

''Mn...'' Omega shifted slightly, but otherwise didn't show signs of struggling.

Groping her ass with his other hand Louis steadied her, scissoring his fingers apart within her and pressing his digits against her walls – feeling said walls clench down on them. Pursing his fingers back together he rotated them around in a circle, rubbing her walls and coaxing out a quiet exhale from Omega, the deity still not showing much sign of difficulty. He had to give her credit; maintaining that position whilst getting fingered was probably pretty difficult. So he decided to spice things up.

Namely by withdrawing his fingers from her pussy, gazing at her lower lips – and then dragging his tongue up it. A sound of surprise escaped Omega but he merely squeezed her thighs and held her still, licking her pussy with eager strokes of his tongue. When he was satisfied he laid two fingers on her lips and spread her open, allowing his tongue to push inside her womanhood; a shiver of arousal lancing through him when Omega let out a soft sigh; the mere sound so strangely arousing.

''Mn... using your tongue in that place...'' Omega murmured. ''Strange... though, it will not be enough, to make me- Mm...''

It was a soft grunt that cut her off; Omega falling silent as his wet tongue stroked over her vaginal walls. Holding onto her thighs he held her still, pushing his tongue in as deep as he could wriggle it and tasting wet arousal, encouraging him to eagerly lap it up – the tangy-sweet taste exciting him. The mere fact that Omega was getting aroused only fuelled that excitement, his head tilting slightly as he worked his tongue with vigour; eating her out without hesitation.

And it was having an effect on her. Though she said nothing Omega began to pant, the deity leaning more on her arms and resting her chin on them for support, stubbornly keeping her back arched and her ass up. His spiced things up as he pleased, from slowing his licks down and taking the time to taste her pussy or wiggling his tongue around rapidly, moving his tongue around in differing tempos – slight tilts of his head helping him to lick new spots within Alpha, coaxing out a quiet hum from the deity.

''Ahh...'' Louis exhaled as his tongue slid back into his mouth; wetting it with saliva before he pushed it back in, tongue-fucking Omega.

His right hand came up and rubbed about as well, tugging on her bodysuit and widening the hole in the crotch area – allowing him to rub at her pelvis, a little nub brushing against his hand. Feeling it he slid his hand down to it, rubbing it and coaxing it out of its hood, the friction eliciting a previously-unheard groan from Omega. Her voice, previously so monotone, now low and almost sensual in how she breathed the sound out.

''Touching that part...'' Omega breathed, twitching when he drew circles around her clit with his finger.

Grinning lightly the young man teased the little bundle of nerves more, his tongue thrusting into her wet sex with renewed vigour – excitement propelling his actions forth. His other hand wasn't idle either and greedily groped her thigh or ass, sinking his fingers into her soft flesh and holding onto her, peripherally aware of how Omega began to pant, her breathing growing heavier as he ate her out. Her inner walls quivered around his tongue the more he teased her, and as he rubbed her clit around with his index finger the deity's hips shuddered slightly, encouraging him to swirl his tongue around in eager circles.

When Omega grunted sharply, tensing – orgasming. It came with little warning, her body tense and taut as her walls clenched down around his tongue, failing to pin it and allowing him to writhe it about her spasming pussy, lapping up her arousal for several intense moments. When he pulled his tongue out his fingers replaced them; two pushing their way into her sex and furiously fingering her mid-climax, eliciting another grunt from Omega, her hips buckling.

But still, she didn't fall.

''Hah, haah...'' The deity clenched her fists a little and then relaxed them; exhaling a long breath. ''That sensation... is a new one...''

''You're still holding that position though.'' Louis noted aloud, genuinely somewhat impressed. ''Still think you can hold it though?''

''Of course...'' Omega's words were breathy. ''This... is nothing...''

Stifling a grin lest he look too eager the young man stumbled up to his feet, fumbling with his belt. It rattled a little as he undid it and shoved his pants down to his knees, letting it sag down the rest of the way whilst he yanked his boxers down with them – leaving his rock-hard cock exposed. He stroked himself off to the sight of her pussy, keeping himself hard and soon getting right behind her, one hand on her hip and the other remaining on his cock. He guided the tip to her wet lips and rubbed against it, the heat of her core easily apparent as he aimed the swollen head against her entrance.

And then at last he pushed in. Inviting wet heat swallowed the head of his cock up, lancing fiery pleasure down his cock and coaxing a sharp moan out of the young man – eagerly grabbing her other hip and pushing himself in deeper. Her vaginal walls were hot as they clamped down on his intruding cock, the tightness that squeezed it so intense he gasped in a breath, shuddering it back out a second later. He didn't slide all of his dick in right off the bat; pushing it just two-thirds before coming to a stop, panting.

''Mn... this feeling... is also novel...'' Omega breathed out, panting lightly.

Louis smiled tightly, squeezing her hips. ''Good. See if you can stay like this until I'm done.''

Omega hummed an agreement, encouraging him to pull his cock halfway back out and plunge it back in moments later, feeling how her walls snugly embraced his shaft. His thrusts pistoned him in-and-out of her tight tunnel, feeling how her walls conformed to the shape of his shaft – and in the back of his mind he wondered if Omega was a virgin, and in turn if he was the first to fuck a literal god. Or whatever Omega truly was. The thought alone fuelled his lust and made him instinctively thrust faster, his cock scraping her wet walls and the tip soon hitting her innermost parts, his pelvis bumping against her ass each time he bottomed out.

Panting with pleasure the young man grabbed her ass and leaned back a bit; spreading her cheeks so he could watch his cock plunge into her pussy, intimately feeling her heat engulf his shaft. He admired the sight for a few moments before releasing her ass and holding her waist, breathing out a moan as he went back to fucking her in earnest; wet claps of flesh echoing throughout his living room as he pounded the tall woman from behind.

''Mn, Mm, Nn...'' Soft grunts escaped Omega, but true to her word she didn't relax her taut muscles. ''Hah...''

Skin smacked against skin as his pelvis clapped against her ass, so loudly he briefly worried that the neighbours might overhear – before realising he didn't care, his grip on her hips becoming firmer as he fucked her without any protection on. He didn't care even if the neighbours waltzed right in and saw them; let them see him fuck a literal deity. The mental image was one that excited him, his hips bucking forth harder and faster with animalistic passion, holding nothing back as he fucked her raw.

Omega gasped lightly at the roughness, her walls clamping tight around his throbbing cock – failing to slow him down as he continued pounding her, his pace unrelenting. Her lithe fingers stiffened and gripped at the floor in an uneven rhythm, failing to truly steady herself as he went to town on her, his pace rapidly growing faster and louder. The resounding clap of flesh echoed off the walls, joined by the young man's lustful moans as he felt heat climb up his cock; being balls-deep in the goddess too much for him to resist, the urge to just blow his load within her vice-like heat too tempting to refuse.

''Ah, O-Omega...!'' Louis half-tried to warn her, his voice waning as pleasure rose up his throat.

''M-Mm?'' The deity's voice trembling slightly as she replied. ''What... is it...?''

The young man attempted to respond – only for a lance of pure pleasure to shoot up his cock, and with a sharp moan he slammed balls-deep into Omega; cumming inside her. The goddess tensed up as she felt the first spurts of semen splatter against her inner walls, unintentionally tightening around his length and coaxing out much thicker ropes that splattered deep into her womanhood; a shudder travelling through Omega's slim frame when she felt it spurt into her innermost parts. Louis kept thrusting even as he came, each subsequent thrust slower than the last until he gradually came to a stop, moaning in bliss

''Hah...'' Omega shifted slightly, panting. ''That... felt strange...''

Louis blushed and murmured something unintelligible even to himself, pulling his cock out of her now-creampied pussy with a moan. Stepping back he gazed at Omega Alpha as she remained with her ass up, giving him a good view of her pussy as milky cum slowly dribbled out, dripping down between her legs and onto the floor, whatever mess made easily ignored compared to the sight in front of him. Something that, perhaps, tempted him to speak up with thinly-veiled eagerness.

''Alright, you win.'' Louis conceded, watching as Omega sighed and slowly lowered herself down onto her knees, sitting up on them.

''That was quite the strange experience. Nothing I was incapable of handling, however.'' Omega noted aloud, speaking in a matter-of-fact tone. ''Though why you did what you did arouses my curiosity.''

''Well... it felt good, didn't it?'' The young man instead said, smiling as he knelt down in front of her – grasping her shoulders. ''We could do it again if you want.''

Omega blinked at him, an almost-innocent glint to her eyes as she tilted her head... before she hummed in consent. ''Very well.''

Louis grinned, and in a moment of boldness he cupped Omega's chin and leaned in – claiming her lips in a kiss. Omega didn't resist nor reciprocated, merely humming in curiosity as he kissed her like she was an immobile mannequin. He pulled back momentarily for air, and when he went in for a second kiss she reciprocated this time, mimicking his movements somewhat and connecting their lips more naturally – the arousing lip-lock joined by the hands that held Omega's slim hips, guiding her onto her back and leaving him on top of her, one hand hurriedly grabbing his dick and jerking it off, getting himself hard for her.

And then with little hesitation he moved between Omega's legs, rubbed against her slit – and entered her once more. Even though they'd just had sex it felt as great as it did the first time, a wave of addictive pleasure washing over the Louis and enticing him to plant his hands on either side of her, moaning as he buried himself up to the hilt within Omega. The goddess shifted slightly and let out a little moan of her own, slightly confused by the foreign sensations she was feeling, yet not opposed to them either.

''Mn... Mm...'' Grunts and groans slipped free from Omega's lips. ''You seem to be... Mn, enjoying yourself quite a bit...''

''Yeah.'' Louis didn't hesitate to admit. ''You feel good.''

''Is that so...?'' Omega murmured, eyeing him even as he leaned his head down. ''As do you...''

Their lips met in another kiss, muffling Louis's lustful moan as he kept pounding the deity into the floor, their pelvises smacking together with every impact. One hand came up to grope at her breasts, her chest practically flat, but the mere act of groping her was more than exciting for the young man – not hurt by their intimate act. The feeling of her cum-covered walls hugging his cock only heightened that, every clenching of her muscles squeezing his cock tight and pulling moans out of his throat, some of them partially muted by Omega's curious kisses.

It was then Omega decided to be more proactive, her thighs rubbing his hips – before the deity wrapped her legs around his waist, locking her feet behind his back and pressing them against his ass, making him thrust into her harder. Gasping in pleasure Louis broke off the kiss and leaned more upright, unable to quell the tumbling moans that escaped his lips; able to only buck his hips forth and pound himself balls-deep into her, any other motion too taxing to even think of doing.

''You're throbbing inside me more now.'' Omega noted, a little out of breath. ''It's making me feel strange.''

''A-Ah? How so?''

''I feel hot. A foreign, yet appealing numbness is growing within me...'' Omega shut her eyes as if focusing on the previously-unknown feeling, perhaps unaware that she was feeling pleasure. ''It is... strange. Yet, I find myself liking it.''

The young man eagerly grinned at that, his hips moving with even more zeal – holding nothing back. The sudden intensity drew a gasp of surprise from Omega, her legs tensing up as his cock slammed between her walls and his pelvis smacked against hers, driving himself into her wet depths with each passionate thrust, as if trying to fuck the goddess into submission. He was doing a good job at it; lust reaching new heights as he witnessed Omega's face twitch, her lips thinning and her brow furrowing as she tried to resist the mounting feelings within herself.

Louis leaned down then, kissing her briefly on the lips and whispering against them. ''Don't resist it, just let it happen.''

Omega shuddered and groaned out an agreement, their lips sealing together a moment later. Her thighs rubbed themselves against his hips as she held onto him tighter with her long legs, the unspoken encouragement only enticing the young man to pound her more; pouring every ounce of strength into his movements.

Until soon the pleasure within his cock rapidly effervesced into something far more intense, a burning rush lancing up his cock-

''Haah!''

-when Omega tensed up and gasped, orgasming for the second time. Her wet walls clenched tightly around his shaft, her narrow tunnel squeezing his girth and immediately pushing him to climax; spurting thick, gushing ropes of cum into her womb. The goddess seized up, back lifting off the floor and lips forming a hot 'O' shape, a soundless moan escaping her as he gave her another, even more intense creampie.

''Ah...'' At last a sound escaped her throat; just as she started to relax. ''Ahh... t-that...''

Omega jerked as he bucked his hips, a groan escaping Louis as he spurted a little more inside, his orgasm gradually coming to a close. Even then he was left panting and gasping in the aftermath, orgasmic bolts of bliss buzzing through his body and leaving his dick practically numb with pleasure.

''Hah, like that?'' The young man breathlessly asked, grinning.

''Yes...'' Omega dipped her head in a slight nod. ''I did enjoy that... may we do it again?''

''You only have to ask.'' Louis gleefully agreed.

And within moments the two were going at it again, Omega's phone still playing away onto the next video, the sound of it failing to mute their shared moans and groans.

X-x-X

The next day Louis returned from the store as usual, having to drop by it after work to grab some beef for dinner.

''I'm home~'' The young man lazily called out, shutting the door behind him.

And as had become routine by that point Omega was sat on the couch, using her mobile phone as she had been the previous few days. It was a good way for her to get more information on the human race from a more human perspective; seeing how they interacted, how news was provided and what little cultural titbits could be found solely through the medium of text and sound, and without physical interactions.

Such lofty ideas however were dismissed from his mind as he approached her, and Omega held up the phone. ''Louis. Regarding the stress-test we enacted last night...''

''Oh... um, yes?'' The young man blushed at the reminder. He'd gotten a little carried away admittedly, but he didn't regret it. Not when Omega didn't seem to really understand it anyway.

That was about to change, however, as he laid eyes on the screen of her phone.

A screen with a familiar black background and orange logo.

''This site... displays acts much similar to what we did. Could you explain why?''

''Ah...'' He began sweating.

'H-How do I explain what porn is...?'

Safe to say he had a long night ahead of him... and also in the weeks ahead, as Omega wanted to 'test' out various acts she witnessed within the videos.

And thus, the internet corrupted a deity.

[END]

A/N: Omega is interesting in that it's implied she's genderless (being a deity of a sorts and all), thus it opens the door to her being able to 'change' genders as she pleases. Another idea mentioned was that she changes gender depending on what the person looking at her thinks, like an optical illusion, though for the sake of smut I went with her just choosing as she pleases~

Hope you liked it~
