A/N: Writing U-410 is always fun, I feel. She's got the right balance of smugness, teasing and charm to work just right in most story contexts~

On another note, I'm actually considering a series as a direct sequel to this fic. That being the Commander gets close with various subordinates and lewd things inevitably happen. Not sure who to all include in it at the moment, though I do know I'll probably focus on Destroyers and Submarines at first, then work up to the gentler Light Cruisers (like Murmansk and Cleveland), then up to the likes of Hood and Illustrious as I move onto the capital ships last, so it's all in a nice order.

I've got a handful of characters I'm toying around with, though if you have any suggestions for Submarines/Destroyers/Light Cruisers you'd like to see included in the first few chapters, feel free to name-drop them below. No guarantee I'll include them, but you never know~

Is it wise for me to start working on another series when I'm already tinkering around with like a dozen at the same time? Probably not, but if you're carrying a stack of boxes, what's one more to the pile~?

That aside, do enjoy~


Tipping Point

''Akashi, I'm really busy today, so make it quick.''

''Yes yes I knyow, so hurry up~!''

The Commander raised a brow at Akashi's continued insistence, following after the short cat-girl as she practically pulled him by his sleeve deeper into her workshop. Numerous spanners and tools littered the floor, half-finished devices and trinkets dotted the worktables, the lights were either bright or dim depending on which table they loomed over; it was a disorganised mess.

But let it never be said that Akashi didn't provide results when she had her mind set on something. Thus the Commander reluctantly took time out of his busy schedule to pay her a visit at her insistence, making the long trek from one end of the base to the other and traversing through her chaotic shop. Still he swallowed his complaints and dutifully followed after her, briefly squinting as he passed through a doorway and stepped into a brightly-lit room.

When his eyes adjusted to the brightness he found himself staring at Akashi's latest invention – a large, tubular machine with a revolving door and various test tubes and other components surrounding it.

''So this is it?'' The Commander questioned, already suspecting the answer.

''Yes!'' Akashi enthusiastically agreed, leading him towards it. ''I've been testing it for weeks now, nya, and it finished its testing phase earlier this myorning~''

''And it... what, repairs ships?''

Akashi looked particularly smug as she spoke. ''Not just repairs them – repairs them in minutes at most, nya~''

The Commander raised a brow at that. Such an invention would greatly aid the war effort, since any injured ships could be restored back to prime fighting condition practically in minutes – taking into consideration the size of various fleets, they could repair entire armadas in just a day, as opposed to a month. Even the Sirens would struggle to counter such a device, and if Akashi could replicate it so they had them all over the globe...

''Interesting. You've outdone yourself this time, Akashi.'' The Commander noted, petting her head – earning a blissful 'nyaa~' from the cat-girl. ''Mind if I check it out?''

''Hm? Sure, nya. It's safe to poke around.'' She reluctantly shifted away from his petting hand. ''I'll get the controls ready for a test demyo.''

The Commander hummed an agreement and made his way over to the machine, inspecting it with a curious eye – knowing enough about machines to appreciate the design. Stepping inside the cylinder he checked the insides for any faults Akashi might've missed in her rush to present it to him, but found none. Not a crack, not a loose wire, not even a drop of leaking hydraulic fluid. Everything was perfectly done.

Outside of the machine Akashi fiddled about with the controls, muttering ceaselessly to herself as she checked, double-checked, then triple-checked the panel to make sure they were all in order – being careful to not actually touch them. Once she was satisfied she stepped back, about to call the Commander over-

-when the metal door leading to the Cattery burst open.

''Nya?!'' Akashi yelped in shock as several Meowfficers escaped. ''H-Hey! Get back inside!''

The several Meowfficers, startled by her cattish cry, skittered back inside with meows abound – but one bold Meowfficer made a run for it. Hopping as fast as its tiny stumpy legs would let it the round cat ran between Akashi's legs, unheeding of her cry for it to stop running. Naturally the Repair Ship gave chase, attempting to grab it, but the Meowfficer was nothing if not nimble and managed to duck and dodge her grabs, hopping on top of tables and ducking under them to put some distance between them.

Until soon it neared the end of the room – and hopped up onto the control panel.

''W-Wait-!''

Faster than the Commander could react the revolving cylinder door of the machine hissed shut – and within a moment a bright blue light flared through the gaps in the metal door, the high-pitched electric shriek not muffling the Commander's startled yell of pain.

Akashi's heart leapt into her chest. ''C-C-Commander!''

Scampering over to the control panel Akashi whacked the big red [Emergency Stop] button, instantly powering the machine down over the course of several seconds. A gout of steam hissed out from the vents as it finished, the metal door clanking before it groaned open once more, allowing even more steam to spill out.

Ignoring the terrified and shivering Meowfficer Akashi tentatively approached the machine. ''C-Commander?''

The steam gradually waned as she approached, her eyes sweeping the small containment cylinder for the Commander... until movement made her look down.

And as the steam finally dissipated, Akashi found herself looking at her Commander. Her much younger Commander, who now stood only a head or so taller than her.

''Ahh... so dizzy...'' The now-youthful Commander mumbled, head spinning and eyes naught but comical swirls.

Akashi on the other hand had a different thought in mind.

'Oh nyo... how do I tell the fleet I de-aged the Commander...?'

X-x-X

The news of the Commander de-aging didn't take long to get out.

Of course there was a myriad of reactions, but when it was discovered to all be an accident most were quick to forgive, not least thanks to the fact that, aside from the Commander becoming younger, there wasn't much in the way of damages – Akashi even assured she could restore him to his normal body... given time. How long was still up for debate, though the looming threat of becoming a skinned cat via Akagi and Taihou certainly helped motivate her.

Thus, aside from triggering some onee-san tendencies in some of the more mature ships, life continued as normal – albeit with Atago under 24/7 watch. The Commander returned to his duties, ships continued sorties as normal; everything was fine and dandy.

Aside from the fact his more youthful appearance made him the target of more affection.

It wasn't inherently bad, but it was most certainly embarrassing having ships he previously saw as subordinates vy for his attention and affection. From Bristol insisting on them going on some private investigations, to Shigure teasing him aplenty, to Ardent trying her best to ask him on a date but ending up just saying it was nothing out of sheer embarrassment; he had no small numbers of Ship-Girls subtly trying to get his attention.

Something that his secretary, U-410, teased him about relentlessly.

''Here's another love letter for you Commander~''

The Commander blushed pink and murmured a thanks, accepting the white envelope from U-410 – the Submarine girl smirking at him before sauntering back over to the filing cabinets. Popping the letter open he read through it, finding it was an elegantly-written letter from Comet asking if he would like to go on a picnic with her. The flowery wording and politeness gave no hint about it being anything more than a friendly outing, but the fact she'd sent him this only after his transformation was a bit telling.

The heart enclosing the envelope only kind of solidified that.

Humming to himself the Commander slipped the envelope into his drawer – briefly banging his knuckles on the wood when reflex made him aim lower than normal. He frowned at that, pausing to move his limbs about before putting the envelope away properly. That was one side-effect of the transformation; he didn't lose his muscle memory. Meaning he kept acting like he was a lot taller than he actually was.

Pushing aside the troublesome thought the Commander slipped out of his chair and made his way over to the cabinets, eyes on one of the files neatly stacked up alongside the others. As he neared though his prior problem came to light as he reached up... and fell just short of actually reaching the file. He could nudge it with his fingers, but it was just an inch or so out of grabbing range.

''Heh. Allow me~'' U-410 came to his rescue, smug as she sauntered up and plucked the file from the shelf – standing just an inch or so taller than he himself.

The Commander's lips moved, already thanking her... had his eyes not noticed a particular detail about her outfit. Namely that when U-410 leaned up, her swimsuit-top rose with it – flashing him even more underboob than her outfit normally showed. Embarrassment flooded his cheeks but a spark of naughty arousal flashed through him, tempting the Commander to bend his knees the tiniest bit, hoping it'd let him see more of her chest.

U-410 caught him in the act, however. ''Hoho, like the view Commander?''

''Ack-!'' He looked away. ''Sorry I-''

He glanced back at her as he started to apologise – only for his words to dry up as U-410 smirked and shamelessly pulled her top up. She didn't do it much, but she didn't need to – showing him her sizeable breasts for a solid three seconds before letting her top fall back into place, tugging it to make sure he couldn't see any more than some underboob.

''Hmhmhm.'' The Submarine chuckled, flicking his forehead. ''You're adorable when you're embarrassed, Commander~''

The Commander had no response to that other than a meek mumble, the image of her breasts glued to his mind for the rest of the day.

X-x-X

Several days later the Commander found himself inspecting the Submarine dorms.

The task was a fairly monotonous one, even after his transformation. It basically entailed walking around the halls, then checking the rooms to make sure each Submarine kept their rooms neat and tidy. Naturally several Submarines didn't and just waved off his chastisements, but overall most of the girls kept their rooms neat and free of junk. Though he noticed the Submarines were much more content to keep him hanging around as long as possible.

Pushing the thought from his mind the Commander approached U-410's dorm door, rapping his knuckle upon it. ''U-410? Can I come in?''

''Hm? Yeah, sure.'' Came the muffled response.

Not questioning her further the Commander unlocked the door and stepped inside – and promptly froze solid as he found himself staring at a half-naked U-410. Her swimsuit was halfway up her stomach, still being pulled up and leaving her creamy back bare to him, the sides of her breasts just-barely visible from his position behind her.

In an instant he slammed the door shut. ''F-Finish dressing first!''

U-410's laughter, no matter how muffled it was, told him all he needed to know – darkening his cheeks with the knowledge she wanted him to see her like that.

And despite his embarrassment, it was a challenge to hide the fact his blood rushed south, and stayed there for the rest of the inspection.

X-x-X

Days later the Commander found himself at the command building like many days before.

Humming to himself he made his way through the halls, shifting several documents over one another as he read through them – having come back from the break room. Without really thinking he opened the door to his office and stepped inside, looking up as he did so-

-and found U-410 bent over, picking up some scattered sheets of paper – presenting a lewd view of her ass to him in the process. Considering she only wore a swimsuit and there was very little to hide her shapely behind, his eyes glued to it even as U-410 straightened back up... and then threw a teasing smirk over her shoulder at him. She was messing with him again.

The Commander pursed his lips; arousal, embarrassment and frustration all bubbling up into a single mess in his mind – forcing him to speak. ''U-410.''

''Yes, Commander~?''

''My room. Tonight. 9PM.'' He crossly said. ''I want to have a talk with you.''

''Oh~?'' She seemed more intrigued than anything else. ''Did I do something wrong, Commander~?''

''You'll find out then.'' Was his stiff answer.

U-410 just cooed and went back to work without a care, teasing him throughout the day.

X-x-X

Night came mercifully fast.

The Commander waited anxiously in his bedroom, hands on his lap and tapping his knees hurriedly. Already he was regretting his decision, wanting to take his offer back, but he needed to set U-410 straight... at least, that was what he should be doing. Instead whenever he thought about the Submarine all he could think about was how goddamn hot she was; how saucy that smile of hers was, how pretty she looked when serious... and how much he wanted to fuck her.

It was an embarrassing thought, truly so, but whether because of hormones or simple pent-up want, he craved U-410. The constant teases she'd sent his way ever since he'd been de-aged drove him wild, from the seductive looks to presenting her ass or even boldly lifting her top up just to flash him – all of it plagued his dreams in the best way possible, leaving him wanting the real thing.

Knock-knock-knock~

The sound of knuckles on wood snapped him out of his dreamy thoughts, warmth flushing his cheeks in an instant. ''C-Come in!''

In response the door clicked open, allowing U-410 to saunter on inside with a quirked brow; shutting the door behind her. ''So, what'd you want to see me for, Commander?''

The Commander stood up from his bed, the dark grey carpet soft under his sock-clad feet. ''I uh... I wanted to talk to you about your... erm...''

''My~?'' Amusement tinged her expression now – undoubtedly knowing what he wanted to say and taking pleasure in his hesitation.

The Commander swallowed, eyes darting to the sides and searching the pale blue walls for any sort of answer... and found none. Leaving him with naught but the blunt truth. ''Can you stop teasing me?''

U-410 hummed, eyeing him for a long moment as a smirk spread across her lips. ''You say that, Commander, but your eyes tell a different story.''

The Submarine took a step closer. ''You say you want me to stop... but I think, you want me to just be more 'direct' with you, hm?''

The Commander swallowed, opened his mouth to speak – and once more the words died on his tongue as U-410 boldly pulled her bikini top up. The red straps dug into her plump, bared breasts as it was hauled up further, letting him see how soft they were as the wires dug in or slid over her pinkish nipples until she finally got her top over her head and threw it to the side, brushing some grey hair from her face. Without losing her seductive smirk U-410 pinched the golden zipper on the front of her swimsuit and started pulling it down, causing it to spill apart and show off her smooth stomach more and more, the zipper soon passing over the crotch seam and allowing it to fall down her legs.

With its absence U-410 was left standing naked in front of him. From head-to-toe not a scrap of cloth remained, her collar being the last to be unclipped and thrown aside before she stood before him with arms languidly behind her back – not a hint of shame on her face as she showed her naked body to him, letting his eyes soak in her sizeable chest and curvy waist, his lustful gaze lingering on her pussy; the sight getting his blood rushing south.

''Hmhm. Seems I was right.'' U-410 purred, sauntering closer to him and grabbing his swelling dick through his pants – smirking at his gasp. ''Let's not play around any longer, Commander. I know what you want...''

She leaned in, lips brushing against his ear. ''...and I'm willing to give it. Now get naked.''

The Commander didn't hesitate to agreement – unbuttoning his white uniform jacket and yanking his arms out of the sleeves, his shirt buttons coming undone with similar speed and leaving both articles of cloth on the floor behind him. His belt came undone with rattle and his pants were shoved down to his ankles, kicked off alongside his boxers a moment later, his socks removed with equal speed.

Stood fully naked in front of her the Commander blushed, his embarrassment only growing when U-410 cooed appreciatively and waltzed around him, admiring every part of him. Her slender left hand landed on his side and traced a line around his back and to his other side, her hand sliding down until she could grab his erect dick – eliciting a gasp from his lips. Her palm and fingers felt softer than he imagined, her slender digits curling around his girth and giving it a slight tug.

''Hmhm.'' U-410 chuckled against his cheek, planting a kiss there. ''Here.''

Taking his right wrist she guided his hand closer to his own cock and uncurled her fingers – coaxing him into grabbing his own dick. ''You can touch me as you want, but only as long as you get off for me~''

The sultry, seductive offer sent shivered down the Commander's spine, a feeble murmur of agreement escaping him. Slowly at first he started stroking himself off, his hand pumping up-and-down his length at a familiar rhythm – whilst his other hand reached out and cupped U-410's left breast. The Submarine cooed at his touch but didn't resist in the slightest, content to just stand there and let him grope her tit; something he did with growing eagerness, sinking his fingers into her doughy breast.

He got more adventurous swiftly; his hand sliding over to her other breast and groping it briefly before moving down to her crotch, running his fingers along her pussy. U-410 hummed at that but once again put up no resistance, letting him touch her as he pleased and admiring his cock as he jerked himself off – his hand instinctively stroking faster as his excitement mounted higher and higher.

Fingers on his cheek made him look up into her ruby eyes as she spoke. ''Mm... sit down~''

The Commander obeyed, stumbling back a single step before sitting down on the edge of his bed. Nary a second later U-410 straddled his waist with a playful smirk, running her hands over her own breasts and hefting them about for his enjoyment, his eyes briefly glued to her chest as he watched her push and heft them about. While she was far from the bustiest girl on the base that didn't matter to the Commander in that moment; she could be flat as a board and it'd still be exciting to him.

His hand reflected that; jerking him off with hurried swiftness and coaxing pre-cum across the tip of his dick. U-410 cooed at the sight and nudged at his hand, making him release his dick and allowing the vixen to shuffle a little closer, her pussy brushing against his swollen shaft temptingly. She didn't take him inside her however and opted to grind on him instead, her rocking waist brushing their parts together.

''A-Ahh... 410...'' He moaned out.

''Heh. Keep actin' cute like that, Commander...'' She brushed her lips against his. ''And you'll get anything you want~''

Any response melted into a moan as U-410 kissed him, her lips sealing against his own and devouring his horny sound. Grasping his slim shoulders U-410 kept rocking her waist and grinding on him, her lips grazing his cock but never at an angle that might let him slip inside by accident, not even when he too started rocking his hips, the friction exciting him more than he thought possible. His hands entertained themselves with her breasts at the same time, groping and fondling her with eager squeezes, committing the size and shape of her boobs to memory.

Then with a slow exhale U-410 drew back from the kiss, flashing him a sensual look as she lifted her hips – her movements halting as she turned around so her back was facing him. The Commander didn't even get the chance to ask what she was doing before the Submarine planted her ass down and continued rocking her hips, forcing a shy moan from his throat as his cock slid between her ass cheeks, giving him something between a lap-dance and an ass-job.

Whatever it was it was pleasurable; arousal flooding his veins and lust tingling up his cock, leaving him swollen and throbbing. U-410 undoubtedly noticed and only teased him further, rocking her hips hypnotically – tempting his gaze down to her shapely behind and admiring her curves. The feeling of her ass pushing and rubbing against his shaft was only slightly pleasurable but the sheer eroticness more than made up for it, coaxing throbs of heat up his shaft, the prospect of cumming from her lap-dance all too real.

Something that perhaps contributed to U-410 slowing down, before climbing off of his lap all together. Before he could say a word she grabbed the back of his head and pulled him into a deep kiss, her tongue invading his mouth without warning and melting his mind in an instant – reducing him to a dumbly-moaning mess. Her tongue dominated his easily and explored his mouth uninhibited, teasing every crevice of his mouth before withdrawing, leaving a thin string of saliva between their lips.

''Heh.'' The Submarine smirked saucily at him. ''Want a blow-job?''

The shamelessness of her words scorched his cheeks, and turned him on. ''Y-Yeah...''

U-410 leaned in at that, brushing her lips against his own and whispering against them. ''Then ask for it~''

If at all possible his face became more red, but lust gave him the confidence to ask. ''B...Blow me.''

''You can do better than that.'' She flicked the tip with her index finger. ''Tell me what you want and you'll get it. Unless you want me to just blow on your cock and nothing else~''

She was teasing him again, but in that moment he didn't care – his dick sore and throbbing with the need to cum. ''Suck me off...''

''Come on Commander, be more descriptive~'' She kissed the corner of his mouth. ''Pretend I don't know what I'm doing~''

''Hah... p-put my dick in your mouth, suck me off until I cum... a-and swallow my load...?'' There was an uncertain lilt to his voice, the attempt at dirty talk sending shudders of shame and arousal through him.

It satisfied U-410 all the same though; a pleased coo escaping the vixen as she knelt down on the floor and got between his legs. ''That's better. How long you been wanting me to blow you, I wonder?''

''Since I met you.'' It slipped out by accident and faster than he could cover his mouth, his eyes widening in surprise at the slip.

U-410's eyebrows disappeared into her hairline. ''Ho-oh~ Been having dirty thoughts 'bout me since day one? How naughty, Commander~''

The Commander just groaned wordlessly back – but any further words withered from his mind as U-410 pushed her face into his crotch, her warm breath tickling his erect cock. Soft, sensual lips caught the tip between them and a wet tongue guided him into her hot, unbelievably hot mouth, forcing a stuttering moan out of the Commander's throat. U-410 took him in even deeper, lips grazing his shaft as she swallowed an inch, then a third, then half, then two-thirds of his dick before she stopped and pursed her lips around his shaft, sucking back up to the tip.

And then promptly pushed herself back down again. The Commander let out a moan of unadulterated bliss, intimately feeling the Submarine's lips slide up-and-down his cock with growing frequency, her hands rubbing his thighs to keep him steady as she gave him head. Putting his left arm behind himself he leaned back slightly so he could get a better view, watching her head of grey hair push into his crotch and tempting him to put his other hand on her head, pushing her down into it.

Her prior teasing though made it impossible to resist her mouth. The masturbation, the lap-dance, all of it was too much for him to handle when he was so pent-up – excitement throbbing up his cock as U-410 sucked on it. Her tongue only made it harder, lashing at the tip with wet strokes or licking around his girth relentlessly, leaving it sticky and wet with her spit. Her right hand soon slid between his legs too and started fondling his balls; squeezing or jiggling them about as if telling him to blow his load right then and there, her wet slurps ringing in his ears.

''A-Ahh, 410, cumming...! S-Swallow it-!'' The Commander barely finished before he finally blew his load - white-hot pleasure lancing down his cock as he came in U-410's mouth. ''A-Ah!''

A hand to the back of her head pushed U-410 all the way down his cock, making the Submarine deep-throat him. Humming U-410 wrapped her arms around his waist, keeping his cock down her throat as he shot rope after rope of heat down it, her muted wet gulps music to his ears. He wasn't sure how long he held her down his dick; time losing all meaning as he rode out his orgasm, hips jerking up and pushing himself against her lips, intimately feeling her tongue stroke the underside of his shaft and coax out every last drop of cum.

Until with a wet gasp U-410 raised her head back up his cock, lips leaving the tip of his dick. ''Haah~ Mm... like that, Commander~?''

The Commander could only moan feebly in response, his dick afire and twitching with pleasure. However he remained rock-hard all the same; something that visibly delighted U-410 and tempted her to straddle his lap with a sensual coo. The sight alone stirred the Commander out of his daze, excitement jolting him back to reality and focusing his gaze solely on U-410, his gaze drifting down to her pussy as she rubbed the tip of his dick along her slit, teasing him.

''Do you want inside me~?'' The Ironblood Submarine teased him.

''Yes, please...'' He practically begged.

That was all that it took to convince U-410, a saucy smirk shot his way before the Submarine spread her lower lips slightly, guiding his shaft in with her other hand. The tip inched inside, her insides hot – when U-410 shamelessly dropped herself down all the way onto his cock.

''Mn~!'' The Submarine moaned blissfully.

The Commander moaned sharply in agreement, tipping his head back on reflex as pure, white-hot pleasure seared down his cock. She was hot; so utterly, blissfully hot, her inner walls constricting his sensitive cock and squeezing him like a fleshy vice. The feeling was unfamiliar yet ever so blissful that it purged any other thought from his mind, unable to think of anything but the searing vice that smothered his cock.

The sensation only became more intense as U-410 started to move. Sensual as ever the Submarine lifted her hips up, her vaginal walls clenching around him and coaxing a moan from his lips – one that rose in pitch as she smacked herself back down onto him, taking him all the way into her slick pussy. The Submarine's own moan joined his, her hands settling on his shoulders as she moved in a sensual sort of rhythm, impaling herself onto him with punctuating slaps of flesh.

''Ah, hah, 4-410...'' He mewled out.

The Submarine just flashed him a smirk, cupping his cheek and pulling him into a rough kiss that left him groaning – reciprocating as best he could. Even doing just that was a challenge though when she was riding his dick, her thighs smacking down against his and his cock sliding between her squeezing walls, the hot grip of her walls wringing heat up his shaft.

Burning lungs forced him back from the kiss but U-410 took advantage of that; burying her face into his neck and sucking on his neck, coaxing a stiff moan from the Commander's lips – the slight nip of pain washed away by sheer, unbridled lust, his hips jerking up and feebly thrusting himself into her. The way she rolled her hips though melted his mind, losing himself in the feeling and just savouring it after enduring so much teasing from the Submarine.

''Heh. You're enjoying it a lot huh.'' U-410 teased him, nipping his ear next and forcing a moan from his throat. ''Makes me wonder how many other girls you'd like having in your lap~''

The Commander shuddered at her words, but U-410 wasn't done yet – words rolling off her tongue as sweet as honey. ''Mm... at this rate, you might as well host an orgy and just bone a bunch of us~ The Submarine dorms can be cosy at night, you know~''

The sultry coo coaxed a feeble moan from the Commander's throat, pleasure throbbing up his shaft as U-410 bounced onto him, her vaginal walls clamping tighter as she put more effort into moving – her flesh smacking against his own as she bounced onto him. Her breasts jiggled just beneath his chin but he was too lost in bliss to take advantage of that, his full focus on the heat swelling up his swollen cock.

But just as the pleasure started to spike, heat swelling up his cock – U-410 lifted herself up and off of his dick.

''H-Huh...?'' The Commander looked up at her, befuddled.

His befuddlement only grew as U-410 frowned down at him; a dramatic sigh soon escaping the Submarine. ''Y'know, you're kinda boring actually. Way too quiet and reserved for my tastes.''

The Submarine hummed, shifting off the bed. ''Maybe we'll do this again when you're less of a coward.''

The words inspired a rare fury in the Commander, fuelled by his frustratingly-close climax – and in an instant he snapped. Faster than U-410 could react he jerked upright and grabbed the Submarine's slender arm and all but yanked her back onto the bed; eliciting a startled yelp from U-410. Paying her surprise no heed the Commander rolled her onto her back and got on top of her, his right hand pressing down on the back of her head and pushing her face into the sheets.

''Mmph?!'' U-410 grunted in surprise. ''C-Commander?!''

The Commander didn't respond; sheer lust hastening his movements and making him grab his cock, lining himself up with her glistening pussy lips – and a hot, relieved moan tumbled out of his mouth as he pushed back inside U-410. Without missing a beat he started to pound her, plunging himself into the Submarine with raw claps of flesh, his pelvis smacking against her ass hard and fast. The Submarine put up a token resistance, grunting and pushing back against his hold, but moans soon slipped past her own lips.

''Hah, that's it...'' U-410 breathed, letting him hold her head down. ''Be rougher. Show me... Mn, who's boss~''

The slight whine to her voice only excited the Commander further, the mere thought that U-410 was getting off on him dominating encouraging him to pound her harder – fucking her prone-bone like his life depended on it. His end was already nigh though; white-hot pleasure lancing up his shaft as he fucked her raw, his shaft scraping her slippery walls and his pelvis clapping her ass-

-until finally his orgasm hit. The Commander gasped, his hips buckling forth and sheathing him deep inside the Submarine – his voice melting into a deep moan as he came inside U-410. The feeling of blowing his load inside a girl felt downright heavenly, his mind purged of all thought as her walls squeezed and wrung him for every last drop of cum.

''A-Ahh...'' The Commander moaned, loosening his hold on her head. ''So good...''

''Mm, that so?'' U-410 murmured, shivering as he pulled out. ''I didn't say you could cum inside though. How naughty, Commander~''

The Commander responded by grabbing her arms and rolling her over, earning a confident coo from the Submarine; her earlier surprise fading back into cool smugness. He didn't mind however; his eyes greedily soaking in U-410's naked body, from her plump chest to her smooth stomach and wet slit, his seed slowly leaking out of the latter. However he wasn't content yet; lust still throbbing up his cock and keeping him rock-hard.

Something U-410 noticed; silently smirking and spreading her legs open, laying her sex bare to him. The Commander didn't need a bigger invitation than that and hurriedly lined himself up, the tip sliding along her wet lips several times as he tried and failed to get it in – and when it did he plunged deep inside, moaning in tandem with U-410 as he sheathed himself deep between her wet walls.

Planting his hands on either side of her the Commander started to move right off the bat, trying and failing to contain his moans as he pumped inside her. With his cum inside her she felt sticky and slick, his shaft filling her with every hurried thrust and fucking moans out of U-410, the Submarine gripping the sheets above her head as he filled her.

''Mn, talk dirty to me...'' U-410 breathed, eyes half-lidded as she looked up at him. ''Tell me what you wanna do to me~''

The Commander shuddered, arousal travelling through him as he complied – speaking every lustful thought that came to mind. ''I wanna rail you until you can't walk straight... I wanna keep cumming in you until I can't any longer... I wanna hold you down and do you until you're raw...''

Heavy breaths escaped him as he kept thrusting throughout, clapping her pelvis with his own and filling her with his throbbing cock. ''I want to fuck against the wall, the window, the sink... Mn, the desk, in my office, in the bathroom, outside...''

''How bold~'' U-410 tried to tease but her words came out more as a laboured moan. ''Mm... I'll let you do all that and more to me, Commander~''

As she moaned the words out U-410 curled her wire-like tail around his right leg, tempting a groan from his throat and hurrying his thrusts – wet, fleshy smacks of flesh driving him balls-deep into her again and again. Slick squelches escaped their joined parts as he stirred up her insides, her walls clamping down tightly and causing some of his cum load to leak out of her, aided by the cock that eagerly thrust itself between her walls.

The lewd words he said though echoed in his mind, further fuelling his arousal. His mind conjured up all sorts of positions and places, aided by the feeling of her inner walls clamping down on his dick – giving a realism to the images. Of bending her over every possible surface, of doing her in all manner of places, of doing so many things to her; many of them ending with him blowing his load in or on her, the desire made all the more acute with how sensitive he was.

''Hah, ah...!'' Panting U-410 snaked her hands up to his cheeks, pulling him down into a kiss – devouring his aroused groan.

The Commander pounded her all the harder for it, arousal tempting him back from the kiss and encouraging him to run his hands to her breasts, groping her shapely boobs. U-410 moaned at his touch and lolled her head to one side, panting as she watched him fondle her with such vigour, his fingers squishing and groping her plump chest like this was the last chance he'd ever get to do such a thing. He pinched and tugged on her nipples, he hefted her breasts about, he touched them to his heart's content – all whilst slamming himself into her, getting off on the slick friction.

The friction only became hotter and more intense as she clamped down on him, a moan bubbling out of U-410's lips without reservation. Shudders and twitches travelled through her slender frame, her hands sliding up his chest and around to his shoulders, pulling him down onto her – keeping their bodies as close as they could as he rammed into her, heat travelling up his cock in a single, powerful rush-

''M-Myn!'' Until finally the Commander climaxed; slamming himself deep into her and filling her with his load.

U-410 pursed her lips, back arching – and with a silent shudder her own orgasm rippled through her, naught but a stilted groan escaping her. The way her inner walls clenched and squeezed his cock betrayed her pleasure though, and heightened the Commander's too; moans tumbling out of him as he forced himself to keep thrusting. His thrust smeared his seed deep inside her, painting her inner walls white with his load until he ran out of energy to move.

''Ah... haah~'' The Commander soon exhaled; all but flopping on top of U-410. ''I'm exhausted...''

U-410 cracked a breathless grin and petted his head. ''Heh... you did well, Commander~''

''...you're not mad that I kinda just pushed you down and boned you?''

''Nah, I was hopin' you do that. Plus...'' Her lips brushed against his ear, allowing her to whisper into it. ''I kinda like it when you're rough like that~''

The Commander's cheeks burned scarlet, eliciting a delighted snicker from U-410.

Safe to say though, U-410 wouldn't be the only Ship-Girl who wanted some time with their Commander...

A/N: I was considering giving U-410 a nickname like the last few times I wrote her - Vierzehn probably - but I passed this time since they weren't already dating, like last time, thus she remained 4-10. Might give her that nickname though if she shows up in the sequel to this fic.
