Mother Material

Caelus was something of a regular at the Herta Space Station.

Be it solving problems, fighting leftover remnants of the Anti-Matter Legion or taking Peppy for a walk, his reasons were many. Today, however, his reason was of much greater importance – namely a text he'd gotten from Ruan Mei.

[Come to the station immediately. We need to talk.]

Naturally when sent a message by not only a Genius Society member, but also a pretty lady, Caelus was quick to comply.

One teleport later and he was on the station, though that soon faced him with a second problem – where was she? He couldn't exactly go around and ask because the researchers probably wouldn't know, given she liked to keep to herself, and Ruan Mei wasn't answering his texts. She was still on the station, that much he could be sure of... but that was a pretty big area to cover, especially if she wasn't staying in one place. For all he knew he could traverse the station just as she did the same, the pair of them eternally looping without being aware of the other.

Sighing the young man scratched his head and looked about the corridor, hoping by chance to just run into her, but no such luck. Considering everything his first hope of finding her was in the Seclusion Zone where all her Creations were located – he doubted she'd be where all the people were, and Herta was perpetually busy doing whatever it was Herta did, so her office was probably out.

Dispelling the thought Caelus glanced ahead as he neared the large sliding door – the motion sensor detecting him and causing it to slide open, revealing the laboratory area that now served as a home for many of the critters he had created in his pursuit of Stellar Jades. Oh and research, but mainly Stellar Jades. You couldn't roll the gacha with research papers after all.

''Ah, there you are Caelus.''

The soft, almost absent-minded comment nearly made him jump – a soft hiss escaping the young man as he tensed and restrained the motion. His eyes though flickered right, spying the very woman he'd been looking for; currently overlooking the room full of critters with transient fondness.

''You wanted to see me?'' Caelus prodded.

It was enough to stir her out of her momentary daze, her eyes flickering to him. ''Ah, yes. I hope it wasn't too sudden.''

''It's fine.'' Was his shrugged response, meandering over and leaning against the railing at her gesture. ''What's up?''

Ruan Mei was quiet for a moment, seeming to think her words over first before speaking. ''I have been trying to spend more time with my creations, per your suggestion.''

''And?''

''They are truly fascinating creatures.'' She espoused softly, a little smile twitching at her lips. ''Their means of communication, their physical properties, their budding civilisation and hierarchical structure – they have been developing rapidly, even adopting tools for their own use. One has learned to make fried rice and operate a microwave, whilst another has gained the dexterity to manipulate a keyboard, allowing it to reprogram robots for their own means.''

''...this isn't going to lead to a robot uprising on the station, right?''

''No. Not yet, at least.'' Had she been anyone else he would've assumed that was a joke, but her straight face betrayed that it very much wasn't. ''That possibility aside, however, my point is that they've intrigued me far more than I anticipated. Yet, I still find myself incapable of giving them the love they so desperately want from me.''

Ruan Mei hummed. ''Thus, I sought out answers as to how to 'learn' to love, or at least express my feelings in a way more easily construed. The result was a rather simple, if time-consuming one. Becoming a mother.''

She looked up at him then. ''Thus, I want you to make me one.''

Had it not been for the mewing of the critters in the background, the silence would've been deafening.

''...come again?''

Ruan Mei merely blinked. ''You heard me.''

''I'm not refusing, but uh... why me?''

''Three reasons.'' She raised a hand, three digits raised. ''First, you are male. Two, you are handsome. Three, I trust you enough to allow it.''

Caelus opened his mouth, shut it, then exhaled. ''I... sure, then. When were you thinking of doing it?''

''Is right now preferable?'' Ruan Mei remarked as she rose to her feet. ''Herta has allocated me a room already away from prying eyes, so it will offer more than enough privacy?''

Warmth coloured his cheeks. ''Sure. Lead the way.''

Ruan Mei hummed and gestured for him to follow, the two of them leaving the critters behind.

Though he couldn't help but spy a blush on her cheeks as they walked, light as it was.

X-x-X

The trip to the room was short – a five minute walk, tops. A very long, awkwardly quiet walk, but he survived.

With a hydraulic hiss the heavy metal rose rose up into the ceiling, enabling the pair of them to wander through the hexagon-shaped opening. The interior was rather spartan, all things considered, with next to nothing in the way of personalisation – there was a beige flower-patterned bag by the double bed, some make-up was on a shelf and some science-y devices were arranged on a desk, but other than that it was plainer than most of the storage rooms he'd seen.

Not that it seemed to bother Ruan Mei. Meandering into the room she pressed a button next to her desk that caused the door to shut and audibly lock, trapping the pair of them inside. A twist of a knob dimmed the lightening from a harsh fluorescent to a more pleasant amber glow, making this feel less like a purely professional environment.

''I am inexperienced regarding this matter.'' Ruan Mei remarked then, breaking the quiet. ''Theoretically I am aware of all the details and necessary actions, but I am not well versed in it, so I apologise for any mistakes made.''

He had a suspicion that was a very roundabout way of saying 'I'm a virgin', but he didn't comment on it.

Instead he shuffled closer. ''So uh... how do you wanna do this?''

Ruan Mei turned to face him, her lips pursing and her brow cutely scrunched.

Before she spoke. ''Drop your pants.''

Though somewhat startled by the request Caelus didn't hesitate to oblige, swallowing as he unbuckled his belt and let his pants slide down his thighs, warmth colouring his cheeks as he bared himself before the pretty genius. The blush on her cheeks only emphasised her cute beauty, his plain grey boxers soon revealed. Ruan Mei eyed them curiously as she knelt before him, her inquisitive expression in stark contrast to her actions as she reached out and undid the front button of his boxers – causing his cock to spring out, semi-erect already.

Humming she curled her fingers around it, her digits dainty and clad in her elbow-length gloves. With a gentle squeeze she started to stroke his length, going from near the base all the way to the tip before running her thumb over the head, the gentle stroke sending a shiver dancing up his spine. One that preluded the moan that weaselled its way past his lips as Ruan Mei squeezed his cock.

''Hm... I would've thought this uncomfortable...'' Ruan Mei murmured as if making notes to herself, her head tilting as she eyed his cock. ''Interesting.''

Caelus kept his mouth shut, a shudder roiling through him as the beautiful genius worked her wrist, pumping his cock like she wasn't doing something terribly lewd. A spike of excitement shot through him then as she leaned in and she noticed, looking up with a brow raised before understanding seemed to dawn on her – bringing a rosy tint to her cheeks as she looked back to his cock.

Before with a soft sigh she leaned in properly, her breath warm against his cock – and then she caught his tip between her lips.

''Nn- haah...''

Ruan Mei let out another curious hum around his cock, the gentle vibrations of her voice ticklish. Keeping her curled fingers around the base the beautiful genius stroked him off as she sucked on his tip, steadily enveloping more and more of his length until she pulled back, her eyes gracefully shutting as she bobbed her head. The lewd noises that escaped her mouth – the gentle sucks, the sticky slurps, the thoughtful hums – all of it just fed Caelus's growing lust.

And when she took him deep into her mouth, he couldn't hope to quell his sharp moan – tensing up as those plump lips pressed near the base of his cock, flush with his shaft as she slurped her way all the way back up his length. The tender embrace soon returned as she descended down his shaft with a gentle vigour, her tongue lashing at the tip before slithering under the shaft, helping guide him in almost.

''Hmn...'' Ruan Mei hummed around his cock.

A fresh shiver shot through Caelus as she curled her thumb and index finger, forming a circle for his cock to thrust through – and her mouth waited on the other side, his cock grazing through the gap and into her lurid warmth. She nearly deep-throated him, his tip grazing the back of her throat and tempting him with the sensation, his hips starting to thrust of their own volition; thinking become nigh-impossible as the genius sucked his cock so meticulously.

Ruan Mei opened her eyes and peered up at him, unflinching even as she bobbed her head with growing earnestness, the welcoming heat of her mouth driving him closer to the edge. His legs felt weak and he had to reach over and hold onto the shelf to his left, his breathing growing shallow and fast as she serviced him in such a manner, the mere idea that he had a Genius Society member blowing him only making it so much lewder.

When Ruan Mei let her hand fall away, and finally deep-throated him.

''C-Crap!'' Caelus gasped, clutching at her head.

Ruan Mei's eyes widened a split-second before he yanked her down, a senseless moan escaping the Trailblazer as he face-fucked the beautiful genius – his cock plunged between her plump lips and straight down her throat. She grunted and gagged in surprise but made no move to stop him even as her used her mouth for his own pleasure; lipstick quickly becoming smeared across his swollen, throbbing girth, her nose squished into his crotch as his swollen balls hit her chin-!

And then he came, shouting in pleasure as he busted his load down her throat. Ruan Mei clutched onto his thighs but he didn't relinquish his hold on her head, gasps escaping the grey-haired Trailblazer as he had the orgasm of a lifetime, his thick, pent-up seed spilling down Ruan Mei's virgin throat. She swallowed hurriedly, nails digging into his thighs as she gulped down the torrent of thick fluid, her eyes beginning to flutter.

When Caelus pulled his cock out and allowed Ruan Mei to gasp, a sudden cough making her cover her mouth; catching her breath.

''G-Goodness...'' Ruan Mei breathed. ''I hadn't anticipated just my mouth would have been enough...''

Caelus didn't reply, if only because he was too busy panting for breath to do so. Ruan Mei though got over her surprise quickly, her countenance becoming almost shy as she rose to her feet – and his attention was firmly grabbed as she undressed. His attention clearly flustered her; warmth colouring her cheeks even as she worked the straps of her dress, the material shifting in places as she loosened parts around her neck.

And them with a thump it fell around her ankles.

'Tits.' Was Caelus's first thought, the horny overtaking his mind as he found himself staring at Ruan Mei's bare bust – no bra or anything underneath to hide the plump curve of her boobs, her nipples a pale pink.

Fancy jade-green panties hugged her hips but her nimble fingers worked their way into them too, a tug peeling them down her thighs and also dropping them around her ankles. The sight of her naked state was more than enough to render Caelus dazed by her sheer beauty – and it wasn't until she grabbed him by the shirt that he snapped out of it. Just in time for her to give him a tug and a push, sending him flopping onto the bed with a grunt.

''I shall lead.'' Ruan Mei noted aloud as she straddled him, her thick thighs touching his hips.

Caelus shivered and uttered a hasty agreement, spending a second to get his pants off altogether and push them down his legs, his cock standing at full mast for her. Ruan Mei hummed at that and grasped his length, her slow, slight strokes teasing a breath out of him as she worked him back up, his cock-head soon touching her petals and grazing her entrance, the closeness enough to make Caelus clutch at her thighs with anticipation.

A faint smile twitched at Ruan Mei's lips and she leaned forwards the tiniest bit, held him firmly – and a soft, prolonged moan escaped her as she impaled herself onto his cock. She did it slowly but the mere penetration sent jolts of relief coursing through his cock; the pleasure of being inside of a woman new to Caelus. One that only became so much more intense as Ruan Mei took more and more of him inside; her moan rising in pitch as she reclined and nearly went all the way down.

Before with a little spring of her knees she bounced back up, leaving just the tip inside of her. It didn't stay that way for more than a second before she eased herself back down again, her slow pace only accentuating how snug she felt around his girth. The way her insides clung to his cock, the press of her thighs against his hips, the soft groans that escaped her lips; all of it just made Caelus hornier, his palms shifting from her thighs to her ass, tracing the curve of her rear.

''Mn... am I performing well?'' Ruan Mei puffed out.

''Very.'' He managed to grunt back, eyes flitting from her curious if tight expression to her bust, watching her boobs heave with her breaths.

Ruan Mei took notice; humming as she reached down and took his hands and guided them up to her chest. Caelus didn't hesitate to accept the offer and sunk his fingers into her generous bust, marvelling at how plump her tits were – soft but with a hint of firmness as he squeezed them together. Ruan Mei bit her bottom lip and moaned as he did so, her slow bounces gaining momentum as she got into the swing of things; practically leaning into his groping palms.

Not that he was complaining; loving the feel of her tits in his hands. The light prod of her nipples against his palms enticed his thumbs to draw circles around them, teasing more breathy noises out of the delicate woman atop him – and in a fit of lust Caelus dropped his hands down to her hips, bucking his own.

''Mm!'' Ruan Mei buckled briefly, her hands clutching onto his shoulders. ''So assertive...!''

Her words just enticed Caelus to do it again, then again and again – each thrust propelled by his ever-growing lust. Initial hesitation drained out of his system as primal passion overtook it, not hurt by the sight of a naked Ruan Mei. Everything about her just drove him wild; her womanly curves, her generous bust, her dainty touch and almost-innocent expressions, all of it just made him hold her tight and slam his cock up into her hot, gripping pussy.

And Ruan Mei rewarded him with her moans; a slew of musical notes escaping the genius as he pounded up into her. She tried to keep moving but the unrelenting pace of his thrusts soon left him the one in charge; the rough tempo causing the bed to rock from the force and bump the headboard against the wall repeatedly, the dull thunks only adding to the moment. A moment that saw Ruan Mei leaning down, her moaned breath tickling his lips – before she kissed him.

Caelus groaned into it, shifting his hands to her ass – and Ruan Mei grunted in surprise as he suddenly flipped them over, pushing her down onto the bed with him on top of her.

The delicate genius didn't have more than a second or two to register the change before he reared his hips back – and a cry escaped Ruan Mei as he drove himself back into her, plunging between her petals with sudden vigour. A penetration made all the easier with how wet she had become, his cock gleaming with her sticky fluids as he pumped in-and-out of her core, her clenching tightness doing little to slow his pounding pace.

If anything being on top of her, his lips mashing against her own, left him intoxicated. With a sharp groan Caelus pressed himself into her with every thrust, his cock fitting snugly within the beauty under him as he wildly bucked his hips like an animal, his hands clutching at the sheets at fist before soon snaking under her; wrapping around her slim waist and holding her close as he fucked her like he owned her.

''M-Mm! Yes... yes, just a bit more...!'' Ruan Mei gasped against his lips, her delicate demeanour cracking and giving way to pleasure. ''Don't- hng!''

In the back of his mind Caelus remembered he wasn't using a condom. That Ruan Mei wanted him to impregnate her. To breed her.

And that thought sent him into a frenzy; growling against her lips as he went to town on the hapless genius. Had he the thought he might've mating pressed her but he was too close now, the risk of cumming real and if he dared slow down he'd suffer an incomplete, meagre orgasm – leaving him with no choice but to keep moving, pumping his throbbing cock deep inside of Ruan Mei even as the woman cried out, her delicate voice reaching such orgasmic pitches it burned itself into his mind-!

Until with a shout he came, bustinghis load inside of Ruan Mei with the single-minded desire to give her a child. The sudden creampie made her wail and dig her nails into his back, the pain muted compared to the wet hotness that strangled his cock, squeezing his pulsing manhood as he spurted gush after gush of semen into her depths, his groin pressing and grinding against her own as he tried his damnedest to get all of his cum deep inside of her fertile, willing womb.

Caelus rode his orgasm out to completion before finally pulling out, puffing out a laboured breath as he leaned back on his knees. Pleasurable aftershocks shook through his form and his dick ached in the aftermath of two back-to-back climaxes, but still remained erect – not least because he had a beauty like Ruan Mei laid before him, gasping and panting for air.

''I-Incredible...'' She got out, elbows touching the quilt as she propped herself upright. ''I think I understand a little more now, but...''

Without hesitation Ruan Mei twisted onto her side and got her knees under herself, ass up and head down as she gazed back at him. ''Once more, please...''

Caelus couldn't hope to resist, arousal a drug that coursed through his veins like a fire. With a hurried agreement the Trailblazer shifted up behind her and grasped his length, guided himself in – and a moan escaped them both as he penetrated her once more. The cum and fluids inside of her made it even stickier than the first time; his cock sliding between her clenching insides. Insides that strangled his cock as he hilted within her, the unyielding grip of her pussy only enticing him to pull out more, no more than the tip left inside of her before he plunged back inside of her.

Ruan Mei moaned sharply in reply, many more noises spilling out as he clapped her from behind – the lurid slaps of flesh filling the bedroom as he fucked the genius beauty doggystyle. The thought lured his gaze along her figure, from her taut back to her shapely ass, his right hand coming down to caress it – before on a whim he brought his palm down, spanking her.

''Mm!'' Ruan Mei moaned suddenly, clutching at the sheets. ''Caelus, that- nn!''

Another spank quenched her voice, reducing her elegant words to a needy moan. The tightness that clamped around his cock sent shudders running through him and immediately he smacked her shapely behind again, awakening something of a domination kink as he bent Ruan Mei over and pounded her wit senseless abandon – the slew of slick squelches that escaped their loins only enabling his ravenous lust.

Ruan Mei was all too happy to accept it. Whereas he awoke a domination kink Ruan Mei awakened a submission kink; her moans deep and plentiful as he rammed into her from behind, breeding her like a bitch in heat, his occasional spanks edging her before the next thrust came. She couldn't even push herself back onto his cock, unable to muster the strength and thus simply accepting the pounding, her cheek pressing into the bed as she endured the waves of euphoria rushing through her.

''Hrn, yes! Goodness yes!'' Ruan Mei cried out, burying her face in the quilt and biting it. ''Hnng~!''

Just hearing his partner make such noises was enthralling, but to have her clenching around his girth, her excitement clinging to his cock as he roughly pistoned into her receptive pussy, was orgasmic. His hands dug into her hips as he asserted a firm hold on Ruan Mei and with a growl Caelus set about pounding hers, knocking her forth before he yanked her back by her hips, driving his cock deep into her tight wet hole.

After enduring two back-to-back orgasms though he knew he wasn't going to last long – a fact reinforced by the aching bliss that steadily crept up his cock, the prospect of cumming inside of Ruan Mei for a second time too tempting to resist. He pursed his lips and kept at it, grunts and groans forcing their way out of him regardless as he railed the woman before him raw, his balls tensing as he prepared to spill his seed inside of her once more-!

''Caelus- ah~!''

When with a high-pitch, orgasmic cry Ruan Mei came on his dick. The satisfaction that roiled through him was enough to push him over the edge, lasting no more than a few thrusts before the tension overspilled – and with a moan Caelus came inside of her, yanking her hips back and burying his cock balls-deep inside of her womanhood. The slick tightness that smothered him only aided in squeezing his semen out, their act as primal as could be as he impregnated her.

Releasing a tense breath Caelus steadily came down from his high, pleasure like lightning as it jolted through his muscles, before with a heavy breath he finally pulled out. A deluge of cum spilled out of Ruan Mei immediately afterwards, dribbling its way down her thighs or pooling on the bed between her legs, the sight enthralling.

As was the words that followed, her hips touching the quilt as she rolled onto her side.

''One more time... just to be sure, please...''

Caelus obliged.

And when Ruan Mei returned to the space station several months later he found her gently caressing her growing belly, her love for her creations growing in tandem with the love for her child.
