You Can Never Have Too Much Nep (Kuro x Neptune x Nepgear)

Nepgear was at an impasse. These funny feelings just started bubbling up inside after her older sister had gotten together with Kuro. They were far from pleasant, however, as whenever she caught them having a moment together, she would often end up imagining herself in place of Neptune. Heck, Histoire was pleasantly surprised when the boy had somehow managed to get Neptune to start working! Granted, it was just a little bit, but it was still work regardless!

In fact, just this morning, Neptune had even tried—keyword: tried—to make something for him when he came on their weekly "pudding dates." The results were as one would expect from Neptune; the whole kitchen blew up in a sticky mess. Histoire found out, yelled at Neptune, demanded that she clean the place up before retiring for the night, and Neptune then had the gall to peer pressure the poor, emotionally confused Nepgear into "helping."

Internally kicking herself for falling for it again, Nepgear grabbed a mop from the closet nearby just to see Kuro enter and whistle at the spectacle; "Wow… uh, did Neptune try cooking again?"

Nepgear nodded, but not before grasping onto the second half of his question; "Again?"

"Yeah, she blew up my kitchen, too. She said something about trying to make her own specialty pudding for our pudding dates. Dunno why I let her, though… Anyways, by the looks of it, it'd be better if I helped with this mess. Your sister is making you do this in your own, isn't she?"

The Candidate sighed, but smiled a 'thank you' at his for his offer. Kuro grabbed the mop from her and a few cleaning supplies moved herself over to another part of the kitchen and grabbed some tools herself and started cleaning up along with him. She was glad he didn't notice that she was red in the face when their hands brushed against each other's just a moment ago.

Thus, the two of them had started cleaning up all around the kitchen from wiping smeared batter off the walls to mopping the floor. Nepgear cast one long look at the unsuspecting angel, who stood in front of a cooking stove, wiping some batter off the walls. She blushed as she watched him, and when the feelings stirred up between her thighs again that was when she knew what she was feeling. It was the same exact feeling she had around the time she stumbled upon him and her sister having sex.

That's right. Nepgear knew exactly how it was that Neptune and Kuro got together in the first place. She had stumbled upon them in the midst of a heated lovemaking session by pure chance. Nepgear would've just walked away immediately, but couldn't tear herself away and watched them all the way till the end. From the look of ecstasy on Neptune's face and the sounds of her intense moaning, Kuro seemed like a very… capable lover.

However, that thought did not come without its issues. Nepgear wanted him, that much was obvious, but she also didn't want to get in her sister's way. Far from it actually, she knew that given Neptune's selfish tendencies, that the chances that she'd be willing to share her first boyfriend were between slim and nonexistent.

She clutched at the handle to the broom she used to clean up broken shards of glass tableware. She looked across the kitchen at a humble Kuro cleaning up his half of the area. The Candidate sucked up a breath and decided to come forth with her inane proposal.

"I-Icarus…?" she said shakily.

"Yeah?"

"You know how… you and Onee-chan are… together?"

"Of course. I love her," Kuro replied with zero hesitation. Nepgear's lips twitched upwards at the amount of emotion he put into that sentence.

'Onee-chan… this is why I want him, too. He's… a really sweet person,' she lamented in her mind.

"I, um… I saw it…" she replied vaguely.

"Saw it? Saw what?" the genuine look of confusion on his face made Nepgear sigh. Why are all the nice guys so dense?!

"I mean… I saw… you and Onee-chan… having… s-s-s-s…" she couldn't get the last part out. But after stuttering a little bit, she decided 'to hell with it' and let it all out. "I saw you and Onee-chan having sex, Icarus."

Kuro's face went beet red; "Y-you… saw?!"

Nepgear nodded, her face's color matching his and he then paled; "N-n-now, now, Gearsy, let's not get ahead of ourselves here. Okay, so, as you saw, Nep and I did have s-sex and we ended up together because of it. But I promise you, that's not what our relationship is centered on!"

Nepgear was only halfway paying attention after he had confirmed that he and her sister gave each other their first time. She stopped him mid-rant and threw herself at him, her hands clutching onto his clothing; "I'm not angry, Icarus. In fact, I'm actually relieved. Relieved by the fact that Onee-chan gave her first to you."

"Oh…" Kuro sighed with relief.

"But would you listen to one selfish request of mine?" she asked. Getting an OK from him, she asked him. "Would you… take mine, too?"

"W-what…?"

"What?!" the shrill voice of Neptune yelled from the doorway.

"O-o-onee-chan?!"

Neptune looked… serious for a change. Kuro guessed that she had inadvertently entered 'Big Sister Mode'; "Nep Jr.? You do know what you're asking, right?"

Nepgear nodded, refusing to look her sibling in the eye; "I'm perfectly aware, but Onee-chan… I… I actually love Icarus in the same way you do. But I never said anything because I didn't want to get in your way. And after seeing you two… do 'it' together, I…"

Neptune quirked an eyebrow and looked towards Kuro. He mouthed the words 'she knows' and her cheeks turned red in embarrassment. But embarrassment subsided immediately when she noticed Nepgear looking like she was about to cry; "H-hey, now. Don't start the waterworks on us…"

"B-but…"

"Butts are for sitting on stuff. Not yapping!" Neptune interjected before Nepgear could say any more self-depreciating things. "It's cool. Just this once, since it's your first time, I'm fine with letting ya get down with good ol' Icarus here."

"O-onee-chan?"

"Wait, don't I get a say in this?" Kuro raised his hand and asked.

"You don't count because you're a guy and obviously you're gonna say yes," she stated offhandedly before turning Nepgear's tear stained face towards him. "Look at this face. This poor, lonely girl wants to jump your bones, if ya know what I mean. Are you really gonna look at her and say 'no?'"

"Well, no, but…"

"Exactly, so…" Neptune pushed the unsuspecting Candidate towards her person of interest. "Get on with it!"

Neptune's shove caused Nepgear to crash into the angel. Her face burned bright red as they looked straight at each other. The girl's face began closing in on his, lips parted as an open invitation for what would be her first real kiss with a boy.

No more words were spoken as Kuro seemingly forgot Neptune's presence and let this proceed as per his bodily desires. Nepgear now indulged herself in speaking her feelings in this form with the intent of having a part of her embedded in his heart.

After sucking and nibbling each other's lips like amorous school students, Nepgear eventually disconnected herself from his lips. She timidly discarded her main apparel to unveil her pink bra holding C-cup breasts and pink, striped panties to him. His mouth nearly watered at the sight and, by instinct, he felt the urge to grab each breast in his hands and play with them.

Noticing how his gaze stayed locked on her breasts, Nepgear lifted up her bra and looked away before muttering; "You can… touch them… if you want…"

Kuro obliged… with a twist. Instead of immediately latching onto Nepgear's breasts, he got on his knees, pushed her panties to the side, and began licking up and down her wet pussy with his hands gripping her buttocks. The Candidate's eyes widened and she yelped; "Iyaaaaah! I-Icarus! I meant I wanted you to play with my breasts! Don't lick down there so aggressively~"

[Nepgear has gained the "Arousal" Affinity!]

"What the goodness?! Not this again!" Nepgear whined.

'What was that?' Kuro thought as he read the sudden text box, never stopping his tongue from tasting Nepgear's honey. If the latter had been paying more attention, she would've noticed her sister coming from behind her. Nepgear felt Neptune's hands grip firmly at her breasts and moaned.

She turned her head to the side to look at her sibling. She then noticed Neptune's sudden lack of clothing; "O-O-Onee-chan~?!"

"Pfft! As if I'm just gonna stand here and watch you two have a good ol' time by yourselves. You two are obligated to let the series's main character in on the action~" Without hesitation, Neptune began playing with Nepgear's exposed breasts. Her left hand pinched and twisted her sensitive nipple while her right hand squeezed and kneaded the soft skin.

'This is too much… My breasts are being groped by Onee-chan… and my pussy is getting eaten out by Icarus… I feel like cumming any second~'

"A-ah…! I-Icarus… Onee-chan… I think I'm about to—HNNNGH!" Nepgear's head reeled back as her first of many orgasms washed over her. She grit her teeth and grabbed handfuls of Kuro's hair as her cavern continued to leak. The feeling of Neptune's tongue on her neck added fuel to the fire of Nepgear's arousal.

Standing back up and releasing her buttocks made Nepgear's legs give out and she slumped onto her knees, her face just inches away from the tent in Kuro's pants. She gasped lightly and her eyes widened, staring at the strained appendage with wonder and lust.

[Nepgear has gained the "Lust" Affinity!]

'Seriously, what is going on?!' the boy thought.

'This is a boy's… This is Icarus's…' Nepgear was so entranced by the lump in his pants that she hadn't noticed Neptune tugging on them, his erect cock nearly slapping the younger sister in the face. That was enough to snap her out of it quick enough to see Neptune run her tongue along the underside of his rod.

"O-onee-chan! What are you doing?!"

"Huh? This is lesson numéro uno in Sex Ed 101 with Neptune, Nep Jr." the elder sibling explained before, with closed eyes, bobbing her head forward and back, licking every part of his dick while sucking with pleasurable force.

The horny Candidate invaded Kuro's personal space, leaning in and planting her soft, moist lips on his own for another kiss. He got a bit daring and pulled her closer as he ran his tongue against her teeth, a silent request for entry.

Nepgear let his tongue explore her mouth, tasting every nook and cranny. He stopped at her tongue, poked it, and then coiling it around his own. She couldn't stop the moans and squeals that came out and she copied his actions. Kuro placed his hand on her left breast, pressing on her nipple like a button with his thumb.

He took things one step further and slithered his hand down from her breast to her nether regions. Nepgear's breathing hitched and picked up the moment his finger bushed up against the top of her mound before they started stroking her sensitive mound slowly. Kuro's fingers went lower, pinching together at the nub of her clitoris. At the same time, his mouth sucks on her breasts intensified causing the Candidate to audibly howl in ragged breaths.

Meanwhile, Neptune had parted her lips and was shallowly admitting the flared crown of his erection into her hot mouth. She heard his heavy breathing and slipped his dick out her mouth, running her tongue up and down the underside of the shaft once more.

She withdrew after a bit and grabbed the other two's attention; "Alright, break! It's time for a change of scenery, unless we want Histy to get all Pissty again~"

Understanding where she was coming from, Kuro and Nepgear hastily bundled their shedded clothing and made a beeline for Neptune's room.

Upon arrival, Kuro was caught off guard when both sisters activated HDD. They soon closed in with Purple Heart leading. Purple Sister was still inexperienced on the matter, but followed suit anyway. The elder sister's nearly-drooling mouth went to his nut sack first, slowly tasting one of his balls and lightly suckling it into her mouth like an ice cube. Purple Sister decided to follow her example by kissing up the shaft and cradling the other testicle in her dainty hands. The longer she went with it the faster she adapted; one example was her licking up and down the length like a popsicle.

The duo soon began running their tongues along both sides of Kuro's rod, occasionally meeting their lips in the middle engaging in an incestuous make-out session. Eventually, they both agreed to quit the foreplay and get straight to the main act. Purple Sister leaned her head on the headboard of the bed, her legs spread wide. Her big sister leaned forward so that their bodies practically melded with each other's, giving their shared lover complete access to their sexes, one still a virgin.

Without warning or indication, Kuro plunged all of himself inside of Purple Heart in one go. The recoil of Kuro's thrusting caused their clits to brush violently against each other's. She almost started salivating as her tongue slipped out of her mouth. Purple Sister pulled her in for another kiss. About a minute or so, he stopped and relieved himself of Heart's tightness—only to switch to Sister's. However, he looked towards the Candidate, silently asking if she was ready.

"Nepgear…" Purple Heart began, holding his length with her right hand and guiding it towards Purple Sister's maidenhood. "This is the last time: are you absolutely sure that you want this?"

Without even taking a moment to think about it, she replied with; "Yes. I… love Icarus. So, I want it to be him that takes my first time."

Nodding her head, Purple Heart turned to the boy to give him the okay. Prodding open her pussy lips little by little, Kuro looked to Purple Sister for confirmation. She nodded instantly, signalling him to go ahead.

With one firm thrust, he drilled his cock all the way inside her cunt, completely claiming her virginity. The Candidate couldn't be happier as tears of both mild pain and immeasurable happiness streamed down her face. Her sister got rid of the first feeling and calmed her down by capturing her in another steamy tongue battle. Meanwhile, Kuro started locked in place, adjusting himself to her unbelievably tight passage. Soon enough, he started thrusting himself forward gradually picking up pace.

'His dick… is churning my insides… I can't stop moaning now… I hope Histoire… doesn't hear~' Purple Sister started moaning with more of a pleasurable tone now rather than a pained one since she was now accustomed to the sensation of his cock burrowing inside her. Two minutes later is when he has switched back to Purple Heart, who accepted him happily.

As more thrusting undulations came, she pressed her shifting breasts against Purple Sister's smaller ones as they shuffled back and forth. The latter was incredibly wet and tight and the boy knew that he wouldn't last long. After Kuro re-inserted himself into Purple Sister, Purple Heart rolled herself off of her to let the two embrace each other in the missionary position so they could lock lips once more. She couldn't resist touching herself as she watched her younger sister make love with her boyfriend.

Purple Sister's legs hiked up around his backside locking together instantly around his waist just as her arms locked themselves around his neck. Kuro's form hunched over her while it was slamming away into her, soon they moaned together loudly when their bodies moved in tangent to one another's.

"I-Icaruuuuus… It's too muuuuch~! I'm… I'm cumming~!" Kuro's hips twitched and slapped against Purple Sister's body as a flood of sperm started filling up her womanly depths causing her face to scrunch up in ecstasy. Her pussy began convulsing, tightening, and releasing as she milked his cock for all of its contents. After twenty seconds of non-stop cumming, Kuro withdrew from her, leaving a cum seeping hole where his penis once was.P urple Sister slumped back on the bed, her chest heaving as she breathing in and out due to exhaustion, a nice sheen of sweat covering her from head to toe.

"Well, you're certainly durable. You pervert~" Purple Heart did not sound condescending when she said that. In fact, she had no problems with her boyfriend being a pervert towards the two of them. "Even after you came inside Nep Jr., you've still got energy to spare~"

"Well, don't worry 'cuz I'll use the rest on YOU!" Kuro shoved Purple Heart onto her hands and knees before plugging himself into her from behind. The speed at which he humped her made her rear jiggle a bit, and Purple Heart's body rocked back and forth on the bed, both not noticing Nepgear looking on in fascination.

The smacking noises her drenched pussy made echoed around the room as Kuro's cock rammed into it, as well as how deep it reached was extraordinary; "Icarus! I'm cumming! I'm cumming all over your hot diiiiiick~!"

Purple Heart had indeed orgasmed on his penis, moaning loudly as she squirted hot fluids all over the bedsheets, as well as clasping his cock, which paralyzed him. Her upper body fell backwards, panting heavily and sweating. Kuro moved his upper body back as he dragged hers straight up, as he started thrusting his hips upwards. Purple Heart knew this was because he had yet to cum and allowed him to continue to have his way with her. His cock reached deep into her womb, and he raised his legs to gain more force to penetrate her. Her upper body fell backwards onto his chest before he violently rubbed her clitoris.

"Are you… trying to get me… to cum again~? If so, it's workiiiing~!" she squealed as she laid down on Kuro's chest while his cock pierced her like a drill. He squirted mounds of fluid that just exploded from her vagina, making loud smacking noises as her orgasm fell onto the floor by the bed, clenching his cock.

Both bodies jerked in spasms. Hot liquid filled Purple Heart's tight pussy, twitching with every shot and tightening even further. It continued squeezing out more semen from the cock that filled her womb even more.

Purple Heart changed back to Neptune as the entire world turned black. She fell asleep, fully content and satisfied just as Kuro extracted himself from her.

"U-um…" the voice of Purple Sister came from beside him. Turning around, he was treated to the sight of her spreading her cavern with two fingers while looking at him bashfully. "I can… go one more time… if you want to~"

Looking down, Kuro realized that he wasn't finished and took Gearsy's offer and re-entered her womanhood. She moaned intensely as he continued to pump her, her boobs moving up and down along her skinsuit and her hair waving around in a curtain of lavender. Eventually, Purple Sister held a hand out for him to stop. She suddenly flipped her body 180 degrees and raised her buttocks to him, wiggling it invitingly. Kuro thrusted his hard-on into her wet cave again, fucking her doggy-style. He watched from behind how her hair gracefully moved back and forth in rhythm to his thrusts.

Her moans were so loud as they echoed in the room. There was no doubt that someone in the Bascilicom could hear, but they were too immersed in their eroticism to really give two shits.

"I can't… I can't bear it any longer… I'm about to cum~"

"Me too, Gearsy. I'm going to cum."

"It's okay to cum inside. I don't mind~" Purple Sister replied before engaging in another tongue sloshing kiss. A few more hard, focused thrusts later and both of them had reached the end. The Candidate's womanhood squeeze and milk his meat for all its worth. Rope upon rope of semen filled her depths for nearly a minute until they separated, Kuro laying between the siblings on the bed.

The back of his left hand fell hard on Neptune's breast and, without opening her eyes, she breathed; "Ow…"

"Hehe… Sorry…"

The next day…

Nepgear could not have been happier as she baked treats for Neptune, humming a cute little tune all the while. She heard the door open nearby and turned to see who it was.

"Good morning, Histoire~" Nepgear greeted cheerily as the Oracle entered the kitchen.

"Oh, good morning, Nepgear (⌒‿⌒)" she greeted back. "You seem rather ecstatic this morning."

"Mmhm. You could say that~"

"On a different note, on my way up here, several of the Bascilicom staff have complained about strange noises during the night. Do you know anything about them?" Histoire asked. Nepgear flinched, but was able to reign it in enough for the pixie to not notice.

"No. I slept like a baby last night," she replied smoothly.

Histoire's eyes narrowed, but she relented nonetheless; "Very well."

When she left for another futile attempt at getting Neptune to do some work, the Candidate sighed in relief; 'Note to self: next time, if there is one, go to Icarus's house…'

Big Nepsy: Hey! When am I gonna get my turn?!

"In a minute, alright?! Chill!"
