A/N: I actually quite enjoyed writing Suruga, her character just lends itself well to cute humour~ Might do something more with her in future~
That aside, enjoy~
Sisterly Love
''Hn...''
It was a cool autumn day that Kii found herself wandering around the base; an annoyed expression plastered on her face and with her hands hanging by her sides. Few others were about in the bitter autumn weather, the skies greying and becoming overcast whilst whilst the trees nearby remained leafless, what few leaves that remained on the stickly branches withering and of faded rustic hues, winter naught but a few weeks away.
Kii didn't particularly mind the weather. Rather, the thing bothering her was that nobody else was around. Most of her friends were either busy, out in the city, or on a sortie, leaving her with remarkably few people to lounge and chat with. She was tempted to strike up a conversation with someone new and maybe make a new buddy, but she honestly just couldn't muster the effort; fatigued somewhat from her training earlier that day and having expended all her novels, leaving her with little to do.
''Hah...'' Sighing in frustration Kii scratched her head, about to turn around and just go to the bar by herself – when she caught sight of someone else ahead of her.
And a broad grin lit up her face as she laid eyes on none other than her own sister, Suruga – currently nose-deep in a book and muttering feverishly to herself. A glance at the cover of the book had something about naval gunnery; no doubt studying for a self-imposed test to improve herself. The thought amused Kii, but out of a desire to not embarrass her sister she said nothing about it.
Instead she walked right up to Suruga and threw an arm around her. ''Hey how's my-''
''Hyaah?!'' Startled Suruga shrieked and stumbled, flustered. ''W-What- Kii?! Don't scare me like that!''
''Yeah. Noted.'' With a wince Kii rubbed her ringing ear. ''Geez, all I did was touch ya and you screamed...''
''S-Sorry...'' Blushing darkly Suruga closed her book and folded it under her arm. ''I guess I was just really into my book...''
''You can say that again.'' Kii snorted, cracking a grin. ''Still, studying? Isn't it your day off?''
''Mm. But training never stops, even if it's the mind.'' Suruga stated – swiftly piping up when Kii opened her mouth. ''And don't lecture me about overdoing it, considering how often you overwork yourself too, Kii.''
At that taller Battleship shut her mouth, sighing dramatically. ''Alright, alright, I get it. Still, learn to kick back once in a while; won't do ya any harm.''
Suruga huffed. ''I suppose I've studied enough for today... I think I could...''
''Great!'' In a heartbeat Kii pulled her startled younger sister against her side. ''Then let's go drinking~''
''E-Eh?! Wait, I didn't agree to that?!''
''Aw come on~ All my usual drinking buddies are busy~'' Kii whined, pouting down at her sister. ''You wouldn't have your big sis go all alone to the bar, would you~?''
''Yes I would! The last time I went there with you that Avrora girl tried to kiss me and you just sat on your ass laughing at me! Now let me go!''
''She was just being friendly~''
''She'd drunk three damn kegs of beer! She was drunk off her ass!''
''And you could've gotten a free kiss if you were a little more bold~''
Suruga scowled. ''Don't remind- ack!''
''Oho~?'' Grinning widely Kii held her sister-ship tightly, preventing her from running. ''Well well, eyes for Avrora huh?''
''Not at all! It was a slip of the tongue! A s-slip, that's all!'' Suruga desperately squeaked out, hurriedly looking around in case anyone overheard them. ''Don't misunderstand me! S-She might be really p-pretty and that damn dress of hers might really slip off but- erm, it's not, y-you know!''
''You're not helping your case, sis. Do ya want me to liquor Avrora up and send her to your room so you can get a good taste of vodk-''
''Absolutely...! N-Not...'' Suruga rapidly lost strength in her words, the last syllables whimpers off of her tongue.
Kii snickered but opted to not tease her sister any further about her what-could've-been lest she make her head implode. ''Alright alright I'll lay off ya. Come drinking though, seriously; I don't wanna be by myself at the bar all alone.''
Suruga grumbled some choice words but agreed all the same, hanging her head with a resigned, long-suffering sigh.
X-x-X
Kii quickly came to realise why Suruga didn't want to go to the bar – and it wasn't because she was afraid she'd nearly get smooches from Avrora.
Rather, it was because she was an absolute lightweight.
''Ehehe... fishy...''
Kii held a hand to her mouth, stifling her laugh as Suruga sat with her head on the bar top, gazing across the room at the fish tank at the far end. The horned Battleship had only drunk three glasses of alcohol in stark comparison to Kii herself who'd already had a dozen tall ones, chugging them back between snippets of conversation. At first Suruga had just become tipsy, by the second glass she was drunk, and now on the third one she was most certainly smashed – the fourth one in front of her only half-empty.
She was half-tempted to just sit there and continue drinking, especially now that Suruga had loosened up, but her sisterly instincts told her if she did that then Suruga would be black-out drunk before her fifth glass and would undoubtedly wake up feeling crap – and would also refuse stubbornly to never go drinking with her again. Thus, not wanting such a terrible fate to happen, Kii sighed and reached into her pocket, clattering some coins and notes on the bar top.
''Here. Thanks fer the drink, 'kashi.''
''Nya~ Thanks for nyour patronage~'' Akashi merrily mewled, polishing a glass with a cloth from behind the counter.
Humming Kii approached her sister ship. ''C'mon sis, time for bed.''
''Okay~'' With a slurred agreement Suruga pushed herself off the bar stool and nearly fell back – had Kii not swiftly intervened, catching her in a bridal carry. ''Ehehe~''
Kii stifled a snort, adjusting her grip on her sister and making sure nobody would get a look up her skirt before making her way to the door. They swung open easily, the air outside door and the night sky reigning above, the air pleasant against her warm skin. Suruga didn't quite think the same, mewling and squirming against Kii for warmth, earning a chuckle from Kii as the taller Battleship made her way towards the dormitory.
It wasn't a far trip, and with naught but a light grunt Kii pushed open the front door with her shoulder, making her way inside. Only a few people were about, most either asleep or in their rooms doing whatever it was they did this late at night – a quick glance at a clock reading nearly eleven at night. Musing on that Kii began planning her morning schedule; going over what areas she needed to improve in and any other obligations beyond training she had, ferrying Suruga up to their shared bedroom at the same time. On the way she felt something poking at her stomach but paid it no mind, assuming it was just Suruga's belt or one of her buttons.
Until soon they reached it up on the quiet third floor. ''Alight, we're here.''
Suruga let out a hum, half-asleep by this point, and with an amused smile Kii plucked out her key and slid it into the door. With a click it opened and then shut behind them, revealing their unlit room – a pinch and twist of the dial turning the lights on only to a dim hue, enough to see but not so much that it was bright. Thus Kii managed to avoid tripping on the potted plants as she meandered over towards their walled-off bedroom, tilting her body so she could carry Suruga on inside, and at last lay her down upon the ready-made futon within.
''And, there.'' With a soft smirk Kii helped prop Suruga's sleepy head up. ''There we... go...?''
Only then, as she laid Suruga splayed out across the bed, did she at last see the noticeable bulge in Suruga's skirt – one that shouldn't be there. Befuddled and a bit curious she reached down, grasping ahold of Suruga's pencil-skirt and tugging it up-
-and gasped when she laid eyes on Suruga's bulging black underwear, the shape beneath unarguably a cock.
Just then, whether stirred by the shifting of cloth or by chance alone, Suruga stirred out of her sleepy daze. ''Huh...? Eh, K-Kii...?''
Kii said nothing; startled silent by the sight of Suruga's futa-cock. And even in her drunken state it didn't take long for Suruga to connect the dots, her gaze shifting down to her hiked-up skirt... before she hiccuped, tears gathering in her eyes.
''N-No... don't look...'' Suruga's voice wobbled, a sniffle escaping her – before practically in an instant she burst into tears.
The sound snapped Kii out of her shock, but before she could get so much as a word in Suruga startled babbling – incomprehensible, drunken babbling made worse by her choked-up voice, only bits getting across to Kii herself.
''I-I never wanted... to see... I just wanted... be like everyone else...!'' Suruga sobbed out, trying to roll over to hide her shaft but unable to find the strength; helplessly rocking before giving up and just pulling a pillow into her face, wailing into it.
''H-Hey...'' Hesitantly Kii shifted an arm under Suruga, helping her sit up – tenderly grabbing the pillow and pulling it out of Suruga's vice-grip with some effort, allowing her to look into her sister's eyes. ''Relax, sis, I'm not gonna be mad... just, y'know, explain...''
With much sniffling, Suruga did. Through her tears the Battleship revealed how she'd always had a cock since the day she was summoned, but when she quickly learned she was an anomaly in that regard, she hid it lest she stand out and draw attention. The lengths at which she had to go to just to hide her futa-cock, and how terrible it was when she had to get changed with all the other girls, carefully avoiding looking too much lest she pop a boner and give herself away. The fact she hadn't yet been caught, despite the pranks done by the likes of Shigure or Shimakaze, was almost impressive.
But also worrying to Kii, the elder Battleship listening to her sister speak with attentive ears. Despite her tough persona she cared for her sister a lot, and she could barely imagine how hard it was for her sister to hide the peculiar aspect of her anatomy – and her easily-frightened state became that little bit more understandable. Her resistance to things like sleepovers or alcohol also became more explained; Kii could only imagine what a drunk, unrestricted Suruga would be like if Avrora playfully made a move on her. It wouldn't take much for Suruga to pop one and give the game away, and while Kii was of the mind that few would mind it, the fact is that word would get around regardless, and that was positively the last thing Suruga would want. She'd probably take death sooner than that.
Kii was stirred out of her thoughts however by Suruga's voice. ''Y-You probably think I'm a freak, huh... g-guess I really am...''
''Hey.'' Whacking Suruga on the head – earning a startled yelp – Kii frowned down at her sister. ''You ain't a freak. You're just you, simple as that. Don't start acting like I'll disown you or something dumb like that – you're just as beautiful, smart and strong as you ever were. Anyone who says shit 'bout you is gonna find themselves in the ground.''
Backing up her words Kii pulled her into her bust, hugging her tightly and caressing the back of her head, soothing her younger sister as best she could. Suruga hiccuped, clutching onto her clothes and sniffling; one step away from ugly-crying but gradually getting a hold on herself, heaving in gulps of air and sobbing back out what she couldn't push down; feeling lighter than she had in months. Kii sensed that and smiled faintly, planting a kiss on her sister's forehead and rubbing her back, murmuring comforting words to her sister.
However her attention was swift to go back to Suruga's cock. Glancing down at it Kii blinked at the sight of it, noticing it looked even harder than before; the shaft thick and throbbing almost painfully. Glancing down Kii realised holding her sister to her bust might've not been the best place to push her head, especially given how drunk her sister was. Thus, with a frown and moment of thought, Kii made a decision.
She grabbed her sister's cock.
''M-Mmph?!'' Squirming momentarily Suruga pulled her face out of Kii's bust. ''S-Sis?!''
''Ssh.'' Smoothly Kii hushed, adjusting her grip slightly and holding Suruga's cock between her slender fingers. ''Let me help you out, sis. You've probably been so paranoid you've not done much with it, have you?''
Suruga's cheeks burned, but she spoke all the same. ''N-No... I just... only a couple times.''
Kii hummed, squeezing Suruga's shaft and starting to pump it up-and-down, her strokes slow and smooth as she got used to it. ''Then I'll help ya. Just relax.''
Suruga whimpered but agreed, shivering as she buried her face back into Kii's bust. Retaining her slight smile Kii responded by stroking her sister off more, hand squeezing Suruga's futa-cock slowly and carefully, just getting a feel for it. She was quite big, her cock almost swollen as Kii massaged it, every little motion making Suruga gasp and whimper – completely new to the sensation of someone else touching her cock.
The thought sparked arousal within Kii, and with a simmering fire in her eyes as began to move her hand faster. Slow, tender strokes evolved and became quicker, her thumb finding the swollen head and rubbing it about – eliciting a sharp, pleasure-filled gasp from Suruga before it melted into a shaky moan of bliss. Then in a moment of boldness Suruga grabbed onto Kii's sarashi and pulled, loosening the carefully-tied bandages and causing them to slip free, exposing her large breasts fully; allowing Suruga to push her face fully into her boobs.
''Mm...'' Kii didn't mind, merely shivering at the feeling of hot breath against her skin. ''You're twitching a lot... bet you must be pent-up, huh?''
''Mmhm.'' Suruga whimpered into her boobs.
Kii smirked a little at that, jerking her sister off faster – caressing the back of her head to stop her from pulling her face out. Suruga's hips buckled upwards from the pleasurable strokes but Kii didn't cease her motions, working her wrist and giving Suruga the best – and only – hand-job of her life, though Kii made a mental note to speak with Avrora. The Northern Parliament woman would be more than happy to assist Suruga with her 'issue', and judging by how Suruga reacted to her playful advances before, the outcome would be obvious.
However as she kept pumping Suruga's dick she got an idea – one that tempted her to squeeze said dick, and then release it. Suruga whined in confused disappointment, panting when she pulled her head out from Kii's bust. Rather than speak however Kii just winked at her sister and laid her down on her back... and then without a hint of hesitation shifted down until she was at eye-level with Suruga's cock.
Suruga realised what was happening, her eyes widening. ''E-Eh?! W-Wait a minute, that's- o-Ohh~!''
A sharp, blissful moan tumbled out of Suruga's mouth as Kii kissed the tip of her cock, and then took said tip into her mouth – sensually sliding her lips around the head and sucking upon it. Grabbing Suruga's wide hips she held her down and worked her way deeper, humming around her sister's cock and sucking back up to the tip again. She moved fast, giving Suruga no time to adapt and progressively taking more of her girth into her mouth, her tongue licking and lashing at the thick shaft in her mouth or the twitching tip until eventually two-thirds of it were in her mouth.
Without missing a beat Kii went to work. Pursing her lips snugly around her sister's cock she slurped back up to the tip, her tongue lashing a quick few circles around the head before she went right back down again, a muted grunt escaping her throat as she gave Suruga head. Her sister gasped and jerked against the futon, hips lifting up and shoulders curling inwards with a whimper of unadulterated pleasure, her eyes nearly watering from the overwhelming pleasure coursing through her sensitive nerves.
''Ah, Kii, Kii, ah~!'' One hand jerked down and grabbed onto Kii's ponytail, gasping, but Kii kept sucking her off. ''No, too good, too good, t-too good- M-Myn!''
Suddenly hot, sticky ropes of cum erupted inside Kii's mouth, taking the Battleship by surprise – both by its presence, and the sheer amount. Hurriedly she swallowed, the salty load gulped down, but more splattering spurts came – aided when Kii deep-throated her sister and kept sucking, dutifully gulping down spurt after spurt of semen. Only after several long moments did the torrent of cum slow, and with a muted gulp Kii slurped her lips up to the tip, and then at last popped her lips off – a final spurt of cum hitting her neck but no more.
''Hah... hah...'' Panting lightly Kii wiped her lips dry, smirking at her sister. ''How'd that feel, sis?''
''Ohh...'' Suruga dumbly moaned back – twitching against the futon and literally drooling, her chest heaving every gasping breath she took. ''S-So good... never came... t-that hard before... ahh...''
''Heh, I'll take that as a compliment.'' Kii teased, rubbing her sister's thighs. ''Came pretty quick there, but since you've never been given head, I'll let it slide~''
Suruga just whined, draping an arm over her eyes in embarrassment. ''Sorry...''
''Don't be, I said I'll let it slide.'' Kii punctuated that with a pinch to the thigh, earning a startled yelp from Suruga. ''Though, if you want to make it up to me...''
Rather than continue Kii instead sat up on her knees, and stripped. With sensual ease she peeled off most her outer layers, ending with her red kimono that she carelessly tossed aside, leaving her half-naked in front of her sister, breasts bared and with only some black side-tie panties to cover her lower half. Fixing that Kii then straddled her sister, smirking down at her furiously-blushing sister and untied her underwear, allowing her to peel them off and dropped them off to the side, revealing her sex.
''K... Kii...'' Suruga shyly stammered.
''Ssh.'' Confidently Kii grasped her cock. ''Just let your big sis handle it. You just lay there... and enjoy~''
Without another word said Kii pressed the bulbous tip of Suruga's cock against her folds, and then impaled herself upon it. Hot pleasure shot through her in a rush, electrifying her insides and forcing a throaty moan up out of Kii's throat, lowering herself down even deeper and taking as much as two-thirds of her sister's cock into her on the first go. Beneath her Suruga grabbed onto her waist with an iron grip, crying out in pleasure as she felt hot flesh grip onto her hypersensitive cock, nearly frying Suruga's mind from the overwhelming rush to her head.
Kii didn't remain idle for long however. Rocking her hips a little she teased Suruga at first, but after barely a minute lifted herself up – and dropped herself back down. The last few inches forced their way into her sex and Kii moaned as she was filled up fully, every inch of her insides stuffed with her sister's cock; the sensation only amplified by the squeal of pleasure from Suruga, her sister bucking her hips up on instinct, lifting Kii up a tiny bit and dropping her back down again a second later.
''Heh.'' Kii smirked. ''I got it, no need to try and hint.''
''E-Eh?! Wait, no, I'm still sensi- TIVE~!''
Another shrill squeal tumbled out of Suruga as Kii began to work her waist; lifting herself up only to drop herself back down again, moaning throatily as she impaled herself on her sister. She was a little wet already but just having something so big in her felt downright heavenly, any discomfort she felt only fuelling her arousal and encouraging Kii to keep moving, her inner walls snugly squeezing Suruga's intruding cock.
The smacking of flesh became more audible as he picked up the pace too; slow rolls of her waist speeding up and slapping her down onto Suruga's shaft. Suruga replied by holding onto her hips for dear life, gasping and crying out – until Kii leaned forwards and pulled her sister's head up, burying her face into her bust. Suruga instantly reacted, both hands leaving her hips and grabbing Kii's ass instead as she unintentionally started motor-boating her older sister's bust.
''Mm~'' Kii moaned, a breathy smirk on her lips as she rocked her body back, impaling herself onto Suruga's throbbing dick. ''Feels good~?''
''Y-Yeah...!'' Suruga gasped out, voice only partially muffled by Kii's large boobs.
Kii purred at that, tugging her sister's head back out of her bust and grabbing her shoulders instead, pushing her down. Pinning Suruga to the futon Kii rode her with more passion than before, a moan arising from her throat as she rode her sister harder and faster, focused solely on getting her big throbbing cock, squeezing it tightly with every tensing of her pelvic muscles. Suruga clearly felt it, holding onto her tightly and unable to quell her cries of pure bliss, going so far as bucking her hips up just to ram her dick into her slick pussy faster.
And it was working. Suruga's cries grew in pitch, nearly becoming screams and only being muffled when Kii covered her mouth with a hand, helping muffle it lest their neighbours overhear. Suruga just moaned into her palm, breath hot and her gasps laboured, eyes screwing shut only to snap back open, soaking in the sight of Kii's naked form as she took her cock deep into herself, the slap of their flesh meeting rising in frequency until they reached a fevered, wet pitch.
''K-KII!''
Kii gasped as Suruga grabbed her waist and yanked her down – before thick, gushing ropes of cum exploded inside of her. The sensation was a new one, sending spasms of bliss up Kii's spine as she felt the thick spurts splat against her inner walls, pumping deep into her womanhood and leaving her shivering, a low moan arising from her throat as she squeezed more semen out of Suruga until her sister had no more to give.
And with a shaky, explosive moan Suruga went slack against the futon beneath her, panting heavily. ''Ah, that was... ah...''
Kii just chuckled, rocking her hips a little and coaxing out a tired mewl from her shy sister, before with a light grunt of her own Kii lifted herself up – shivering when she felt Suruga's still-hard cock slip out of her, cum dripping out of her not a moment later. The sensation was a weird, but arousing one... but also left her craving more, not helped by the fact she hadn't gotten to cum herself yet.
Thus with a smile Kii shifted off of Suruga's lap and crawled just a few paces away, fully aware of the eyes on her – before she knelt down on all fours with her ass facing her dearest sister, tempting her with a slow shake of her ass. ''C'mon, don't leave me hanging sis.''
A moment of silence, and then a flurry of movement. Practically fuelled by pent-up lust alone Suruga got behind her and grabbed her hips, whimpering as she pressed her cock against Kii's ass and grinded against it, the friction alone getting her off. Amused Kii reached under herself and held Suruga's twitching cock between her index and middle fingers, guiding it lower down – and let out a throaty moan as Suruga plunged all the way into her on the first thrust.
''A-Ah...!'' Suruga gripped her hips. ''Kii... you feel way too good...''
''Mm, thanks~'' Kii just sighed back, in bliss. ''Just don't cum too quick this time, 'kay? I wanna finish too.''
Whimpering out a feeble agreement Suruga nodded, rearing her hips back with a shiver – and then moaned as she slammed right back in. Kii gripped at the futon sheets under her, pleasure curling up her spine as Suruga repeated the motion, slowly but powerfully pumping into her slick sex. The pleasure made it hard for her to move quickly so Kii helped her along, pushing her ass back and impaling herself onto her sister's wet dick.
That apparently was enough to trigger Suruga. Without warning her sister pulled out – and then slammed back in with force, hips shaking as she slammed into her sex over and over again, their flesh smacking loudly together. Kii gasped and gripped at the sheets, startled by the sudden intense pounding, but a moan of pleasure soon bubbled up out of her throat. Her inner walls tightly clenched around Suruga's cock but her sister kept pounding her all the same, crying out in bliss as she railed her.
And then suddenly pulled out. Kii buckled in shock, startled – and yelped as Suruga suddenly rolled her over and threw her onto her back. Egged on by sheer lust Suruga then spread her legs apart, guided the tip in, and then went right back to pounding her.
''Mn!'' Kii gripped at the sheets on either side of her. ''F-Fuck, harder!''
Suruga just gasped back, planting her hands on either side of Kii and slamming her hips forth, their pelvises loudly smacking together as Suruga bottomed out inside Kii repeatedly, every inch of her pulsating shaft squeezed tightly, as if begging for another creamy load. Suruga seemed all too happy to provide it, her voice rising in pitch as she relentlessly pounded Kii into the bed, one hand even grabbing onto her large breast and groping it as she pounded her.
The intensity, the roughness was unexpected – and Kii loved it. Moaning throatily she grabbed Suruga by the back of her head and yanked her down into it a kiss, sealing their lips together and muffling Suruga's own moan of bliss, their pelvises loudly slapping together. Wet squelching sounds were audible as Suruga rammed her cock into her relentlessly, stirring up her clenching insides and pushing the cum in even deeper it felt like, some of it oozing out around Suruga's shaft as she made room for another thick load to fill her with.
''Mm!'' Digging her nails into Suruga's shoulders she held onto her, tightening up. ''Fuck, S-Suruga, don't stop...!''
With a cried agreement Suruga obeyed, railing her with furious bucks of her waist. Another kiss partially muffled their moans but did little to stifle the sound of their flesh clapping together, and in a moment of sheer lust Kii wrapped her long legs around Suruga's waist, pulling her sister in deeper and preventing her from pulling out. Suruga however had no intentions of doing so; the feeling of being inside her sister's pussy too blissful to consider pulling out, even if it risked possibly getting her sister pregnant.
The thought alone was the nail in the coffin; a rush of heat shooting up Suruga's cock in an uncontrollable rush – before with a shriek she slammed into Kii, and came.
''M-Mn!'' With a muffled grunt Kii tensed, a spasm thrashing through her body as her own orgasm hit, melting her mind momentarily into putty – leaving her able to feel naught but the hot seed pumping into her womb.
Kii twitched, shuddering as she felt spurt after spurt fill her, each one shorter than the last as Suruga spent her load. Slowly she came down from her orgasmic high, the fog lingering over her mind gradually fading as she exhaled a moan, a light grunt escaping her lips when Suruga collapsed on top of her with a sleepy moan of her own.
''Hah... well, that was somethin'...'' Kii breathed, idly petting Suruga's head. ''You good?''
''M-Mm...'' Shakily Suruga agreed, pushing her face into Kii's shoulder. ''T-Thank you... for accepting me... Kii...''
''Heh, no problem sis.'' Kissing Suruga on the head Kii reached over and dragged the futon cover over them, feeling a bit sleepy. ''See ya in the morning.''
Suruga slurred out some half-drunk, half-sleepy remark.
And within minutes both sisters would fall asleep, Suruga atop Kii and with her cock eventually going soft inside her.
