"Not going to ruin their date to the aquarium?"

"Not going to drug them with date rape pills?"

"Touche." Momo responded as she tried to hack into Naruto's computer again, but he had changed the password again. She didn't get to find all of the porn the last time that she had entered it, and she was pretty sure that Mikan wasn't going to be helping her with it this time. She had until the end of their date to go through all of his porn videos, images, and games to try and find herself a common theme and create a plan around that theme. "... You wouldn't happen to know the password this time, would you?"

It was a long shot.

Mikan typed it in with one hand.

"If he changed it this soon, I bet it's FuckYouMikan... and there we go." Mikan guessed the password correctly again. She knew him well enough that she could guess practically any password he could come up with, and if she didn't get it right on the first try, it was usually on the second or third. She wasn't even pissed at the direct statement against her, she sucked on the popcicle in her hand and sat down next to Momo.

-Hours Later-

"I don't get it... he has these porns games, but almost NONE of the Scenes are unlocked... it's like he just hasn't figured out how these games work." Momo rubbed the back of her head in frustration. She looked through the scene galleries in each of the games, and only 1 or 2 scenes were unlocked in each game.

An Ending Scene and maybe 1 or 2 scenes in the game itself that sometimes couldn't be avoided.

"Naruto hates losing." Mikan stated simply.

"Eh?"

"Naruto hates losing, even in games like this, so I doubt he even knows that you get events for losing as a female heroine. Male or female player character, he just does not like to lose." Mikan stated with a somewhat bored tone. She herself had tried what Momo was currently trying, to figure out Naruto's fetishes with the games.

Naruto played these Role-Playing Games JUST like if they weren't porn, he plays them seriously like they were fighting games. Which usually let to Naruto getting "Good Endings" with most of the times, despite the fact the games were designed so you could enjoy getting a bad ending and making things as lewd as possible.

"... Why do you know that... about the core concepts of these games?" Momo asked with a furrowed brow.

Mikan just stared at her.

"Uh, because I'm a teenager too, and since Naruto has porn, I've read it, played it, and watched it when he is careless with it." Mikan just deadpanned at Momo. She didn't understand why Momo was so surprised, since it would be pretty bad if she had NO interest in sex at all. It was kind of hard to having an instinct to populate with no sexual desire.

Momo just stared at her.

...

'Right, Mikan in my timeline only had Rito, who never had porn hidden anyway in his room, and never played these games. This Mikan grew up with a second older brother, who IS a bit of a pervert.' Momo realized another startling difference in her mind, that this Mikan had.

This Mikan was so similar in aspects like teasing her brothers that sometimes she forgot.

This Mikan was willing to use violence, was more experienced with sex related topics, was more cynnical in general, and was smarter. Mikan was mature in her timeline, but THIS Mikan was more mature emotionally than even her own Mikan. Not only that, but she was slightly more athletic. While their bodies looked very similar to each other, this Mikan had more physical stamina than her own did. She was limited in her physical speed and strength, but keeping up with a brother like Naruto had left her with some serious stamina.

"What is your favorite game?"

"I don't know, I don't get THAT into them... I usually play them enough to get off, then I stop playing. I can't exactly make a save file or anything, or Naruto would KNOW I play them." Mikan crossed her arms. She was limited to only playing Naruto's games, and using Naruto's porn for her needs, because she couldn't buy any for herself. She couldn't make a save file without giving herself away, so this led to her not playing the game itself and just searching for the porn scenes. "... how do YOU know about these games?" Mikan asked with a raised eyebrow.

Momo thought quick.

"Space Internet."

"... What?"

"... The Space Internet can connect to Earth's Internet... and I've downloaded a few of these games... WAH!?" Momo shouted as Mikan grabbed her tail and started to play with it. Momo was on the ground in moments, curling up as Mikan manipulated her tail like it was a stress toy. Her opened wide from the pleasure, and she could see that Mikan didn't seem to believe her in the slightest.

"Now, the truth."

"Space Internet, I'm just addicted to Earth porn!"

"Truth, you're going to keep cumming until you give me either the truth, or an answer that actually makes sense. Lala knows literally nothing about Earth culture, so Space Internet is not a thing." Mikan forced Momo to cum, not caring that she was pretty much jerking off a girl to do it. She was going to get every answer that she felt was satisfactory.

"Just play along with my lie, and I'll help you get with your brother! Please, my tail is even more sensitive than usual!" Momo begged as the lightest touch to the tip of her tail forced another orgasm to rip through her loins. The coffee ground massage that cleaned her tail of all of the dead skin had raised her sexual pleasure by 1.7 times what it had been before at least.

Momo felt Mikan let up slightly.

"... Explain." Mikan didn't let go of her tail, but she stopped touching it sexually.

"I've got a harem plan, I want to make him a Harem King. You are the Not-Blood-Related Sister, if you play along with my lies... I'll work to get you into the harem for sure." Momo admitted she was lying, and Mikan caught that but didn't comment. Momo didn't bother to hide the fact that she was lying, since Mikan was smart enough to catch onto her lie to begin with.

"Harem... plan?" Mikan slowly repeated.

"Yes, harem!"

"... Are you retarded?" Mikan asked with with a tilted head.

"Eh?"

"Are you retarded?" Mikan asked again with dead fish eyes that told stories that Momo didn't want to know the endings of. She just gulped and twitched in pleasure as Mikan gripped her tail a little tighter. "Naruto isn't interested in me at all, so what can YOU do to make him fall for me? Even if I were to admit that I'm in love with my brother, he would never return my feelings. He has Lala, and there is no way he would pick me when he has her." Mikan spoke with absolutism in her voice.

"Naruto fell in love with a girl even more flat than you are!"

"... What?"

-1 Lengthy Explanation Later-

"Okay... so you told me the truth... right?" Mikan asked with crossed arms.

Momo had admitted the truth.

"Yes... and the Naruto in the world I witnessed... his first crush was on a girl that is older than you, but even less developed. Flatter ass, smaller tits, and less emotionally mature... if a version of Naruto could fall for THAT girl of girl, then YOU do have a chance." Momo was red faced and sweating. Mikan had squeezed every ounce of truth out of her that she could, which had also forced her to climax more than a few dozen times in response to her interrogation.

People liked to think pain was a great tool for interrogation.

Pleasure was a better tool, because your pain could block out pain if you experience too much of it, but pleasure could become so great that it was painful, and your brain was unlikely to block it out. Momo had just experienced that firsthand, and she was starting to truly understand just how much of a sexual weakspot her tail was.

Mikan had a LOT to digest.

"... This... makes perfect sense and no sense at all... so you're from a dimension, that was watching a dimension with my big brother in it... but he was a ninja... but in your dimension I only had Rito growing up." Mikan couldn't imagine her life without both of her brothers in it, so hearing there was a universe in existence where she only had the 1 brother was hard for her to imagine. She tried to imagine it, and she just couldn't.

Momo moved her tail out of Mikan's grasp.

Mikan crossed her arms as tightly as she could, she had small boobs, but she wasn't completely flat either. She looked at them, and she sent a subtle glance back to her butt, where she frowned slightly as she compared herself to Momo.

"In my original timeline, the Harem plan wasn't working, and when your brother had his Pervy Luck stolen from him... the plan was destroyed. That luck..." Momo pointed to a bottle that she recognized. She recognized that bottle as the bottle that had once contained Rito's perverted luck. "... exists inside Naruto now."

"So Naruto is ALSO a lucky pervert?"

"No... it is hard to imagine, but as time goes on, Rito's sexually repressing himself will make his perv power increase even more than it is now. Right now he just gropes girls... that will go further and further, and the end result of that growth in perv power is what exists inside of Naruto."

"Somehow, THAT is easier to believe than the other dimension thing." Mikan actually had the sense to joke about that.

It was the most believable thing that Momo had said.

Hearing that Rito's luck was going to get more powerful the more repressed he got also validated Momo has telling the truth, so she had a lot to consider.

"So, the harem-"

"Thank you Momo, now I know that I have a chance." Mikan interrupted Momo and stood up, putting her hand on her chin in thought. She turned around and started to walk away, her mind already working in overdrive.

It was easy.

It was easier for her to convince herself that she only loved Naruto as a brother, when she didn't believe that she ever had a chance. She KNEW that her parents were hoping that she would get together with Naruto, she knew that for a fact. Her father always subtly pushed for her and Naruto to grow closer, and her mother was a lot more direct with her approachs. They wouldn't be happy until the family Naruto came from TRULY became part of their family in not just law, but in action. Still, since Naruto was always surrounded by girls who were after him, girls much more developed than herself, she didn't think she had a chance.

So she gave up hope that she had a chance.

"Sakura Haruno... thank you for being a flat chested, flat assed girl." Mikan spoke as she ignored Momo.

Mikan looked at her own small boobs, and her butt with more appreciation now that she knew that they were more than acceptable. Knowing that a version of her brother was capable of having feelings for a girl even less developed than her was enough of a boost to her confidence. She had the support of her parents, she had the support of her brother Rito, and she had the support of Momo as well to push her forward.

"The harem plan?"

"I'm the enemy to your harem plan until you can show me results." Mikan stated as she looked back at Momo.

"What?"

"Get Naruto to fall for me, and only then will I allow your harem plan to continue... as a reward. I'm not going to support a harem of girls surrounding him, if I'm not one of them. I would rather JUST Lala have Naruto, than Lala and a whole group of girls have him without me." Mikan proposed something that scared Momo.

All or nothing.

Momo was now put into a position where she had NO CHOICE at all but to prioritize getting Mikan into the harem first and foremost, because this Mikan was the greatest threat to the harem plan. In her own timeline Mikan had always been a thorn in her side when it came to the plan, but this Mikan was far more dangerous to her planning. She was smarter, more cunning, and more willing to use dirty tricks.

There were no negotiations either.

"... Deal!" Momo had no problem accepting that deal.

"Good, we're in agreement." Mikan stated with a smile.

Mikan left.

"... She scares me." Momo shivered the second that Mikan was gone.
