School is a heck of a wild ride, eh? Sorry for my absence recently. Here's a commission I did for Neptune x Nepgear. Hope you guys enjoy!

"Awww… I really wish Neptune would help out around here for once!"

With an exasperated cry of exhaustion, the Planeptunian CPU's sister vented her despair. Histoire had wanted the both of them to work on tidying up the Basilicom, mainly their rooms. Unfortunately for Nepgear, and to be expected of Neptune, the older sister had ran off to who knows where to do who know what, leaving her alone to do all the dirty work. She normally didn't mind doing all the cleaning for Neptune, considering the CPU would probably only complain, plus Nepgear herself had the attitude of a happily married housewife when it came to work. The only thing she really didn't like about the situation, though…

"Haaaa…"

Is that it was fucking hot outside. Sunshine blared through the windows, the beams relentlessly beating down on any of Nepgear's exposed skin it could. Even with the AC pouring out its amazing chills into the building, she was building up a sweat with all the lifting and moving she was doing. "Goodness," she started, "Why does Neptune have so many NURF blasters in her room?!" Speaking to no one in particular, the candidate expressed her dismay towards the fact that so many of the toy guns were scattered across the room. It wouldn't have been that bad if it wasn't for the fact that they were all the heavier blasters, with several D batteries each. Not only that, but Nepgear was about to scream from how poor Neptune had maintained these poor things! Nepgear was gonna take extra special care of them and…

Some time later, the candidate had finished taking care of the whole mess that was Neptune's room. Overheating from the boiling room, and sweat involved with moving around an abnormal amount of heavy objects in the CPU's room, she weakly went and flopped down on the bed to get in a moment of rest. That moment was short lived. "Daww, the bed isn't even made!" She complained, hints of frustration in her voice. With a sigh, she admitted defeat. "I guess I should get to that now, then…" Jumping back up off the bed, she leaned over and began to make the sheets nice.

And that is when a set of stealthy, quiet footsteps started to approach the bedroom. With the door open, Neptune saw her adorable little sister hard at work, doing what she could to make her life better and easier.

...Or at least that's what the bigger sibling should have seen. Instead of thinking of thankful things to say, Neptune's mind was racing like a custom-made drone, thinking of only one emotion: lust. Her original plan was that she was going to surprise Nepgear and give her a tiny friendly scare, but as she looked at her younger sister she just couldn't stop herself. Every, single, part of the candidate triggered suggestive thoughts in her mind. Nepgear's tender thighs, her stockings that were tightly compressing her legs, damp with sweat, the girl's ever so slightly short miniskirt barely failing to hide the girl's white with pink striped panties, and last of all; the hot, musty air she smelled began to make the CPU's womanhoodgrow slightly damp as her body went from comfortably cooled by the air conditioning to burning with mindless lust.

Nepgear, completely unaware of Neptune's presence in the room, finally stood straight up as she marvelled in the beauty of the neat and tidy bed. Then, she loudly yelled in surprise as she felt a hand come and smack down on her ass firmly before giving it a squeeze.

"Oh Nepgeaaaar, my lovely sister…" Neptune began to coo as she closed the door behind them.

"N-Neptune!?" The candidate responded. First the sudden groping, then the seductive whispering, and then the door closing behind them? Nepgear felt a chill down her spine and goosebumps slowly formed on her arms and legs as she quickly figured out where this was headed. She didn't know why it was heading in this lewd direction, but she knew and didn't stop believing that it definitely was taking a midnight train going not just anywhere, but specifically there.

"You've been such a good sister, but…" As Neptune's response petered off in volume, she slowly brought her hand from one of her sister's cheeks and towards the ridge underneath them. With a less than subtle movement, she extended her middle finger and slid it across Nepgear's soft panties, aiming for where her sister's delicate and sensitive area would be. Near instantly, she knew she had stroked the pleasureful folds of flesh when Nepgear gave out a cute, short, high pitched "eep!"

"Being in that kind of position, just barely showing your panties like that… I'd rather get yelled at by Histoire than be teased this much!" And she fully meant that. For the past few weeks, Neptune had been seeing Nepgear in a more suggestive way. Between the accidental flashing of underwear, her cute moans when she stretched, and the new strong, flowery smelling shampoo that she had been using recently, Neptune had felt mostly lust towards her.

"S-Sis? W-What are you- Waaah!" Nepgear began to stammer out in confusion, but before her question could be answered, the girl behind her quickly turned her around and pushed her onto edge of the bed. Landing with a soft pomf sound, Nepgear fell into a sitting position. Before the candidate had a chance to ask any questions or return to her standing position, Neptune lowered herself down onto her own knees and gripped her sister's thighs, keeping her legs pinned down onto her bed.

With her lips curling into a cheeky grin, Neptune asked her sister a smugly rhetorical question. "What does it look like I'm doing, Nep Jr.?"

Nepgear watched with little resistance as her panties were pulled downwards by the CPU, her only sign of any disapproval to the situation she had being a brief remark. "B-But that's forbidden love!" She quickly sputtered out before her face began to intensely redden with blush as Neptune gazed at her uncovered womanhood.

With a lick of her lips and an accompanying soft giggle, the older of the two sisters confirmed her motives. "Don't give me that, Nep Jr. I've seen how you take peeks at Uni when she leans over, you 'accidentally' touch parts of her body you shouldn't be touching…" Nepgear's blush became increasingly more intense as Neptune teased her, but she nearly yelped when the sentence was finished. "I even found where you keep your nudes of Uni you took with your hidden cameras in her room."

The poor candidate shouted out in surprise, shock, and embarrassment. "H-How did you find those!? D-Did you tell anybody?!"

Neptune laughed out loud before responding. "Don't worry, I'd neeever tell anyone about your secret. Neveeeer… And how I found it? That'll be my little secret." With that cheeky remark, Nepgear let out a sigh of relief. If Neptune had revealed that secret of where she kept her lewds, then she probably would've had to kill her with a pipe wrench or something similar. Her sigh came too soon however, as she then yelped in surprise once more as Neptune brought her face mere inches away from her sensitive bits.

The candidate felt a small chill around her nether region as her older sister took a deep breath through her nose, making sure to take in her sister's scent. And then, with no indication or warning whatsoever that she was about to do so, Neptune took a quick lick at the sensitive folds of flesh in front of her, earning her an enticing, startled gasp from the younger sister. "N-Neptune!" The candidate cried out. Disregarding her sister's call, the CPU began to push her tongue against the womanhood before making a long, extended stroke. Not wanting to stop the pleasurable feeling now pulsing from her waist, Nepgear offered no resistance to the privacy invading girl between her legs. Instead, she rested both of her hands gently on the top of her head.

As Neptune bravely began to make long strokes with her tongue, pushing and sliding it against Nepgear's most sensitive area, the candidate began to lightly hum and moan. With lewd thoughts invading her mind, Nepgear loosely wrapped her legs around her sister's torso and began to gently grind her hips against Neptune's face, trying to wring as much pleasure out from the girl's tongue as possible. Soon after the CPU noticed the candidate's initiative, she let out a small giggle and kept licking before thrusting her tongue forth, parting the delicate folds of Nepgear's womanhood.

This action caused Nepgear to gasp in a quiet yet surprised tone. As her body was played with more and more, she grew ever closer and closer to reaching her limit. A twitching vibration happening in her nethers tipped off to Neptune that what she was doing was working, and it was working very well. Her moans began to increase in volume and pitch and her grinding increased in pace as Neptune began to go deeper and quicker with the thrusts of her tongue.

Before too long passed, the overwhelming stimulation Nepgear received became too much for her to handle. Releasing a loud, orgasmic cry into the air, she signalled that her limits had finally been reached. Her legs once more wrapped themselves around Neptune's upper body, tightening their grip on the CPU in order to keep her head close to the nether region she was so focused on licking. Accompanying her legs, Nepgear also moved her hands from the top of Neptune's head to the back of her head, helping her to pull the older sister even closer.

As the candidate's mouth hung open in order to let out sweet, pleasured moans, so did her womanhood. Quickly, Nepgear's sex juices began to gush forth from her body, helplessly spilling over into Neptune's mouth. With intense, passionate fervor, Neptune began to thirstily lap up the sweet love nectar that came forth in a steady stream. Helping Nepgear to ride out her orgasm, the CPU pushed her lips against the girl's slit and began to suckle on it, allowing her to both provide intense pleasure to her sister whilst also drinking the lovely fluids overflowing from her body. In response, Nepgear helplessly released more mewls and groans as her grinding grew more intense. It wouldn't be too far of a stretch to say that by this point she was practically humping Neptune's face.

Eventually however, the pleasure high eventually came to an end. With her womanhood being drained of its fluid reserves, Nepgear panted heavily in exhaustion as she struggled to breathe in enough air for herself. Despite the orgasm being over, the candidate still kept her legs tightly wrapped around Neptune as she began to recover. She took deep breaths of the hot air that practically reeked of sweat and sex, and then released a sigh of exhausted relief. She just wanted to stay like this for a little while…

…

SMACK SMACK SMACK

Nepgear, shocked at the slaps hitting her thigh, looked downwards to see Neptune, cradled in between her legs. "G-Goodness!" She cried before loosening the grip she had been keeping on the CPU this entire time. Freed from the prison that was Nepgear's crotch, Neptune started taking in rapid, deep breaths to recover lost air. One thing Nepgear had forgotten, it seemed, was that Neptune couldn't breathe if she was that close, and that she too also needed air to breathe.

"Nep Jr…. Your thighs almost killed me!" The CPU teasingly complained to her younger sister.

"S-Sorry!" The girl stammered apologetically in response, not quite sensing the teasing that was in Neptune's voice. "I just got lost in the moment and figured you were fine and so I just kinda stayed there and and and-!"

"Calm it, girl!" Told Neptune. "I'm fine, I'm breathing now, there's nothing to worry about. Except…" Looking downwards again at her younger sister's soaked nethers, a mischievous grin formed on her lips. With a plan equally mischievous as the grin on her face forming in her thoughts, Neptune leapt onto the bed, not giving Nepgear any time to change her underwear or even pull it back up.

"S-Sis?" Nepgear started to question aloud as she watched Neptune get onto the bed. "Why are you getting on the be- waah!" Her sentence was promptly interrupted as her bigger sister pulled her away from the edge of the bed and towards the middle, letting her back rest on the bed's header as she sat on top of a pillow. "W-What are we gonna do on the bed?"

With a devilish smirk formed by her lips, Neptune quickly crawled and closed the short distance between her and her sister. The younger of the two sisters began to sweat lightly as the older one leaned in closely. As soon as Nepgear began to open her mouth to question the girl's intentions, Neptune finished closing the distance between them by planting her lips on Nepgear's opened mouth. The candidate's eyes widened in shock momentarily, but after only a mere few moments she cast aside her will to resist and returned the kiss.

With Neptune having initiated the liplock, she had already slid her tongue into Nepgear's mouth by the time Nepgear had accepted the kiss and tried to return it. The candidate allowed her sister to be the aggressor, letting the CPU's tongue roam freely inside of her mouth. Neptune took full advantage of the permission she had been granted, beginning to immediately lick and feel around the inside of her sister's warm mouth. Starting off slowly, she lightly pushed around Nepgear's submissive, passive tongue, before moving to the walls of her cheeks, pushing against them as if to test them. Having made her initial exploratory movements inside the young girl's maw, Neptune began to speed her tongue up, greedily clashing against the other's.

That is, until Nepgear suddenly struck back, unexpectedly lashing her tongue out and pushing the fight into Neptune's mouth as the candidate took control of the situation and began to explore her older sister's mouth. Neptune began to panic once she lost control, weakly pushing against the warmth in her mouth yet failing to repel it…

"Hrmph!?" Nepgear shouted as her body shuddered and she let forth a passionate moan that was muffled into nothing more than an echo into Neptune's mouth. Fortunately for the CPU, she had prepared a backup plan for just this. The moment Nepgear took control, she had been ready to thrust not one, but two fingers into the candidate's womanhood. Truly, a master plot.

Desperately trying to regain control of the situation that she had just obtained, Nepgear tried to shove her tongue into Neptune's mouth once more. Her comeback was halted immediately by the older sister pulling her fingers back and thrusting them in once more, causing the candidate's entire body to shudder and spasm momentarily; a moment which Neptune capitalized on to the fullest extent. With lust and desire fueling her movements, she shoved her tongue back into Nepgear's mouth again, and began to explore it with force. However, just because she had regained control didn't mean that she wasn't going to pull out her fingers and do nothing. She knew exactly what she wanted to do with her hands.

Showcasing complete dominance of her younger sister, Neptune licked around Nepgear's mouth while thrusting her fingers in and out, back and forth at a moderate pace. With surprising sensations running through the her nerves, Nepgear pleasantly moaned into Neptune's mouth, giving her an enjoyable echo to reward her fingering efforts.

The two continued this song and dance for a while. Neptune would hold dominance of the situation before Nepgear would try to challenge her sister, but then she would be repelled by the person whose tongue she was dueling with as they sped up the rate at which they thrust their digits inside, making sure that she nudged any of the more pleasureable points when she could. Eventually, after enough time had been spent dancing with their tongues and fingers, Neptune pulled out her digits and moved away from the kiss. Nepgear, logically, was confused as to why she suddenly stopped.

"Nep… tune?" The candidate asked between heavy breaths as she tried to recover from Neptune's onslaught of smooching and tongue fighting. The older sister of the two, after having recovered her breath that she had lost from the elongated makeout session, began to unzip her oversized parka without saying a word to Nepgear, leaving the younger sister completely confused and flustered. "Neptune!?" She stammered.

Finishing what she had started, Neptune fully unzipped her paka and threw it off to the side and onto the floor, revealing her bare, unclothed chest, including her unsubstantially sized breasts and their nubs. Finally, as she began to pull down her own white and blue striped panties which were visibly soaked with her juices, she gave Nepgear a response. "What? I can't have you being the only one havin' fun here, Nep Jr.! Poor little me has been doing lewd stuff to you the whole time, while my body's been aching for some action with my cute lil' sis!"

"O-Oh," Nepgear muttered, "I guess that makes sense then, Neptu- wah!" The candidate, simply pondering to herself rather than paying attention to her sister momentarily, was caught off guard when her legs were spread apart by Neptune before she slowly nudged and slithered her way like a snake right next to her. With Neptune's movement complete, having brought their womanhoods pressed together and interlocking their legs in the process, she could continue onto phase two of her plan.

As Nepgear was still busy trying to understand what her sister was doing, the CPU began slowly gyrating her hips, which in turn caused both of their nethers to rub against each other. This lewd action elicited a pleased, savory moan from Neptune, and a shocked, yet pleasant yelp from Nepgear. No longer did Nepgear have to worry about comprehending what Neptune was doing- she had a feeling she would feel it. With the hip motion pleasuring both of the girls at the same time, Nepgear felt amazing, almost overwhelming sensations of ecstasy from her womanhood. Not able to think properly, her mind began to focus on the pleasure, and her hips practically began to move by themselves.

Grunting with satisfaction, Neptune coyly smiled as she looked at her sister and stuttered out in a pleasant tone, "T-that's a g-good girl, Nep Jr.! I-I didn't- ah- think you had it in ya!" More than happy to have her sister eagerly participate in the sex, Neptune gave her sister praise and cheered her on in her typical playful voice, even though that voice was breathless and regularly interrupted by her own moans. With renewed vigor and more intense, passionate fervor, Neptune now rubbed herself against Nepgear with more pressure, not only moving her hips around, but pushing her body towards the candidate to apply a pleasant force between them.

The echoes of a chorus of ecstatic moaning and breathless gasps filled the musky, sweaty air that now reeked of sex. Nepgear would push against Neptune, simply moving her inexperienced hips up and down to rub against Neptune's dripping wet nethers. Then, the two would trade dominance as Neptune began her offensive, her small, more experienced body making her hips not only go up and down, but rotate from side to side, push against Nepgear's body, and gyrate in a circular motion, blessing both of them with intense pleasure to their eager, wet sexes. This cycle went on for some time before the candidate spoke.

"N-Neptune, I-I'm going to…!" Nepgear sputtered out with breathless anticipation, as her legs began to quiver, her teeth began to reactively clench, and most importantly, her pussy began to twitch with pleasure in how close she was to reaching her climax.

"S-Same here, Nep Jr.!" Responded Neptune in a hasty, excited breath. No more than a few seconds later did the CPU's hip movements grow furiously more intense and sporadic, grinding against her sister with passion and desire, before finally…

"C-Cumming!" The both of them shouted as intense, powerful bursts of sensational and pleasing shockwaves shot through their bodies, causing the CPU and candidate to shudder and shiver. Nepgear's juices shot out of her womanhood, clashing against Neptune's own love nectar and combining, before some of the resulting fluid splattered and got on Neptune. Still spurred on by their orgasms, the two kept grinding their hips together for a long time after their orgasm ended, doing all they could to savor every last feeling of pleasure they could before they collapsed in exhaustion.

"Haaah… I never knew you had it in ya, Nep. Jr…. has my little sis' been practicing with Uni all this time?" Neptune teased in between heavy, desperate breaths while she took in air.

Nepgear blushed in response to this statement. If it wasn't for the fact that she was winded and too busy breathing, she would have responded to that statement with embarrassment dripping from her voice, but for now she ignored the question and simply tried to get her breath back.
