A/N: Hello and welcome to my first lemon... Oh how far I've fallen, but you know what? I'll never get any better as an author if I'm too afraid to try new things. So yeah, hopefully I'll be able to do a fairly good job with this, I dunno, but I'm gonna try either way. So please remember to leave some feedback since it really helps me out and I'm always eager to hear what you all think, especially since this is my first lemon. So without further ado, Let's get on with the show you've all been waiting for!

-~-~-~-~-Harem Building 101-~-~-~-~-

"Hey there ladies and gents, I'm Neptune, protagonist extraordinaire!" A purple-haired girl could be seen standing within her room, giving a grand speech to all those that existed beyond the fourth wall. " I would like to personally welcome you all to my latest and greatest idea. I am going to teach you all the proper way to build yourself a harem, you dig?"

Seemingly out of nowhere, another girl appeared, looking almost identical to Neptune, aside from looking older and bustier.

"And I'm here today with my lovely assistant to help me out today. Big me!"

"Hi hi!" The older and bustier Neptune smiled and waved energetically alongside her smaller counterpart. "Little me here is gonna be teaching you guys about seducing different types of girls for a harem, so clean out that wax in your ears and grab yourself some tissues because this one's gonna be a doozy."

"Why thank you, my lovely assistant." With introductions out of the way, the smaller of the two Neps took her taller counterparts hand and began leading her towards the bed, where she happily took a seat and awaited the fun that was to come.

"Thank you, my adorable other self." And as soon as the taller of the two Neps got herself comfy on the bed she took out her phone and immediately dived into a particularly fun game of Huffy Avians: Galaxy Wars Edition. While the taller Nep found herself engrossed into her game, the other of the two Neps went back to her original position to pick up where she'd left off.

"Alright ladies and gents, how many of you have ever wanted your own harem? Don't even bother raising your hands cuz I know you all have!" The purple-haired loli pointed a finger forward as if to emphasize her point. "Well have no fear, let good ol' Nep show you the ropes. After all, who better to show off the basics of Harem Building 101 than the main character of all main characters, am I right?"

The cheery purplette then took out a clipboard from... I don't even want to know where, but took it out nonetheless and began reading off the different archetypes she knew she wanted for her harem.

"We're gonna be teaching you guys all you need to know about seducing different types of girls." The CPU then produced a pencil from out of nowhere and began checking off the many boxes found on her list. "Tsundere's, Sporty girls, Scrappy girls, Weird science loving girls, but that's not all. We've got ourselves a special treat for today only, the elusive doppelganger trope."

In response to her smaller counterpart's declaration, the bigger Nep looked away from her game for a second and gave an energetic wave towards the non-existent audience.

"So let us begin, shall we?" At that, the older-looking Neptune stood up and made her way to her lolified self, feeling just as excited as the smaller girl at the prospect of what was to come. "So first we begin with a little explanation on what these characters are like, so take it away, sexy me!"

"You got it, mini me!" Giving herself a mock-salute, the bodacious Nep looked forward once more. "A doppelganger type of character is one that is identical to the main character in the way of personality with a few quirks here and there to give them their own pizzazz... Wait a minute, how many harems even use that character trope anyway?"

The smaller Nep raised a finger as she... Couldn't come up with an answer... "I dunno."

The loli purplette shrugged her shoulders, slumping them in defeat right afterwards.

"Wait! We can still salvage this." Only to regain her usual spunk and take hold of her pencil once more as she vigorously got to work on making modifications to the list. "There we go!"

The bigger of the two looked over, giving her smaller self a look that screamed "way to go" all the while. "The peppy moe girl trope? As expected of me, we are so awesome."

"You know it, me!" Both Neps beamed with triumph, looking proud of themselves. "Now let's get on with it."

"Righto." Now that the two had properly given the lovely readers a good idea of what this little fiasco was going to be about, it was time to start this whole debauchery in full-force.

"So, the first step in seducing the sweet moe girls is... Actually, you probably wouldn't need to actually do all that much." The chibi Nep stopped for a moment, finger to her chin. "The sweet moe types usually really like the main character just because they're all nice and stuff don't they?"

"Oh yeah." Mimicking her other self's motion, the big Nep thought on that for a moment. "They're all so head over heels for the main character that they pretty much seduce themselves."

"..."

"..."

"Meh, whatever." The two spoke and shrugged in unison.

"Well hey, that just means we can get into all the juicy stuff ASAP." Mini Nep pumped a fist as big Nep joined her.

"Yeah, It's time for the fun part of our lesson." The bigger Nep took hold of her small counterpart's hand, eagerly leading her lolified self to the bed.

"Let's Nep-nep!" It was time! It was finally time for the two to not only complete phase one of the lesson, but to metaphorically take this story's virginity and make it earn its M-rating. It was time to Nep Nep right in the Nep as hard a Neppingly possible.

The bigger of the two sat herself upon the bed, beckoning the smaller Nep with a seductive waggle of her finger. The purple-haired loli gladly moved closer.

"Kyah!" She was also taken by surprise when her older-looking counterpart grabbed a hold of her and pulled her closer, wrapping her legs around the smaller girl. However, she wasn't done yet, slowly leaning in, planting a light kiss onto her loli self's lips.

"Mmm." The first kiss lasted only for a moment, but the loli wasn't satisfied with just that. "Wha- Mmmm" She closed the gap, locking lips with her other half, but this time, she didn't stop at just a kiss, licking her other self's lips, enjoying the flavor of pudding they offered. It only took a matter of seconds before she was granted access into her partner's mouth.

The first stage began with a dance of tongues, swirling around each other, exploring each other's mouth. "Mmmm." It was an all around fun time for the twin Neps, but it seemed as though the bigger of the two wanted to take control of the situation as she began to suck on her partner's tongue. "Mmmm!"

That single act left the loli Nep feeling a little weak in the knees. The bigger Nep on the other hand felt herself heating up at the sensation, specifically towards her lower regions. The smaller girl let herself lean on her partner, relishing the feeling of her tongue being sucked on.

After few more wonderful, very very wonderful seconds of sucking, the bigger Nep pulled back, letting go of her loli self's tongue while embracing the girl into a big hug. Not even five minutes in and the two were already beginning to feel wet, but for the moment, they simply enjoyed themselves as they held each other, taking in each other's scent. It was a moment of much needed intimacy before the main event could really get underway.

"Nepu." The loli CPU said lazily, still enjoying the smell of lilac given off by her partner. "It's time to Nep it up." And without warning, the loli pushed the maker version of herself onto her back, earning a yelp from the taller girl.

"Oogh!" The shock only lasted for a moment as she quickly gave in to her smaller self. The CPU Nep took the opportunity to take the zipper of the Maker's sweater into her hand as her counterpart did the same, slowly undoing each other's bindings. As the two took off their hoodies, the were left to stare at each other's bodies.

The CPU Neptune may have had a small bust, but they just looked so perky and cute that it would be difficult to not want to have fun with them. Whereas the Maker Neptune had a bigger and bouncier chest that looked perfect for sticking one's face into.

"Hugh!" Which is exactly what mini Nep did, wearing a goofy look of utter bliss on her face all the while. After a few seconds of enjoying her counterpart's fun bags, the CPU raised her face just enough to start licking away at her partner's nipple. "Kyah! You're so bold, mini me!"

It didn't take long before big Nep's nipple found its way into mini Nep's mouth, earning a few groans of pleasure from her partner. However, big Nptune wasn't just gonna be some little school-girl who let her senpai take the lead.

"Kyah!" Before the CPU could do anything about it, the tables had turned, leaving the loli on her back as her older self happily returned the favor from a few seconds ago. This caused the CPU's eyes to roll back as her nipple was sucked on while the other was being played with by her partner. It wasn't a bad feeling. In fact, both Neptunes could get used to doing this.

Mini Nep decided to just sit back and enjoy her other self's tongue. Although...

"Hey, what'cha doing with your hand?" She was drawn out of her little inner monologue by the feeling of her other self's hand slowly making its way down the loli's body. She didn't really get a response to her question either. "Nepu!" Unless having a pair of fingers diving into her panties counted that is.

The bigger Nep could only grin at the sound of hearing herself moan. "Mmmm!" But that all changed when the Nepu nation attacked. The smaller Nep wasn't one to lose either, as she reciprocated her taller counterpart's action. The action only seemed to make the two feel even hotter, leaving them to sweat like crazy as they rubbed the crevice in between each other's legs.

The pair was left to mindlessly rub away at each other, quickly closing in for another passionate, deep kiss. They could feel themselves tensing up as they got closer and closer to that special moment of sheer bliss that they oh so craved. The two pulled away, looking at each other once more. No more words needed to be spoken now, it was time for the piece de resistance.

In the blink of an eye, two pairs of panties fell to the floor, leaving the two Neptunes completely exposed to one another. Tossing all formalities aside, the older Nep dug in. "Oooh!" The feeling of having her fingers inside herself yet at the same time not, was both as confusing as it was erotic. She could feel her smaller self's insides wrapping around her fingers as they explored deeper and deeper still. But since she was dealing with herself here it didn't take very long before she had a pair of finger exploring her insides.

The two kept up the act for a while until they decided to have a taste test, sticking their fingers into the others mouth, tasting, sucking, all around enjoying the taste. It was sweet, fragrant, maybe not pudding flavored, but still really good. "Mmmm." Really really good, so much so that they had to kiss to get the full effect of what the other was tasting. They pulled back, a trail of saliva connecting them, slowly falling down onto mini Nep's chest.

And as one might expect of the two Neps, their thoughts were in the exact same place. "It's time to Nep this in the Nep." At this point, the two shifted positions so that they had a front row seat to the other's private areas. And as natural progression would have it, they quickly began licking away gleefully at each others crevice, thoroughly enjoying the liquid crawling down their thighs and butts.

It was such an addicting feeling that the two found themselves licking faster and faster, moaning louder and louder. They licked and played with each others bodies, rubbing away each other all the while. After only a few more seconds the two's bodies began tremble more and more, eyes rolling back, until... Until...

"NYAAAAHHH!" "UWAAAAAAHHH!"

They couldn't hold it in any longer and sprayed each others face full of their love juice. Thoroughly exhausted, the two rolled off of one another, panting and sweating profusely.

"That was awesome." The first to recover was the bigger Nep. "We gotta do that again some time."

"You betcha, you sexy vixen you." It was obvious that the two would be doing that more often during their free time, which they happened to have a lot of... Double the Neps equals double the fun after all. "Alrighty ladies and gents. I hope you were watching, because that is how a main character takes care of business." The loli CPU took the liberty to sit up.

"Yeah, a main character isn't supposed to get all wussed out. We're supposed to get things done and get the girl." The maker Nep quickly joined her. As for why they still weren't putting on any clothes... Well, Neptune's always been a pervert.

"Well it doesn't always work out that way, but hey, that doesn't mean I can't at least get on a girls good side." Truly the wisdom of a main character was something to be respected.

"Yeah!" The bigger of the two pumped a fist. "We main characters gotta get stuff done. We're supposed to inspire others to achieve the levels of awesomeness that we set out for them and that includes making a harem." When did this turn into a motivational speech?

"And that's why you gotta stay tuned for the next part where I'm gonna be going after..." As the CPU Neptune looked through her list once more, she came to an abrupt realization. "It doesn't say who's next!"

To which the Maker Neptune looked over it with her smaller self. "You're right! Then I guess that means we're just gonna have to wing it."

"Then there's only one thing left to do!" With one last joined motion, the two posed dramatically like a pair of twin sisters about to take the world by storm. There was only one thing left to say now.

"Let's Nep-nep!" And Nep-nep they will... After taking a shower first seeing as how the two were sweating up a storm on the bed. "But first we gotta take a shower." I just said that.

"Wanna go another round when we get inside?"

"You know it!"

... The protagonist, ladies and gentlemen...

-~-~-~-~-Harem Building 101-~-~-~-~-

A/N: Well there you have it, I'm probably the first person to write a fic where Neptune has sex with Neptune. And as previously stated within the story, I will be tackling, or rather, Neptune will be tackling to herculean task of attempting to properly build herself a harem... Wish her luck. But in any case, which girl would you like to see her tackle first? I've set up a poll on my page where you can vote on who you guys want to see between the four girls I've chosen. "Who are the girls?" I hear some of you asking. I will actually be keeping that a secret until they actually get their own chapter. So yeah, go get voting so that Neptune senpai can show us how a real main character convinces a girl to join a harem... Or at least how she would go about it. Also, this story is mostly here to fill the void that was left behind thanks Secrets Are The Color Purple going on hiatus so I do hope it keeps people satisfied until it returns, whenever that may be. Well in any case, I hope you all enjoyed reading chapter one of my first lemon and I hope to see you guys in chapter two. See ya there!
