Sasuke just stood there, as he tried processing everything. Naruko fell out of the women's restroom. Naruko would have been hurt as a result. Sasuke came to the rescue. Found Naruto instead, on the floor, where his sister should have been, clutching his knee.
One second….
Okay maybe two….

"...Where's Naruko?"
TenTen slapped herself on the face. SERIOUSLY SASUKE, SERIOUSLY!? SHE'S RIGHT FUCKING THERE! But alas TenTen kept her furious thoughts to herself.
"Uh…not here?" Naruto commented nervously.
TenTen was pulling at her hair buns. Why, why couldn't Sasuke figure it out!? She practically laid everything out for him and he STILL couldn't get it?! … for an A plus student Sasuke was pretty dumb.

"I can see that." Sasuke then offered Naruto his hand. "Need help?" Naruto sighed in relief and took Sasuke's hand as he helped him up. Naruto then winced. "How'd you get that injury?" Naruto began to panic. He had to think of something-!
"Uh, Naruko fell on me and she ran off…"
TenTen just stood there dumbfounded as she saw Sasuke nod understandingly.
"You've. Got. To. Be. Kidding. Me."
"What?" Sasuke asked TenTen confusingly.
TenTen jolted as she realized she had said that out loud.
"Oh ah nothing…heh heh…"
She then glanced at the ground and chewed on her thumbnail. She had to think of another way for Sasuke to figure out the truth. Before she ended up killing one of them…

Sasuke then looked around and sighed. Naruko was nowhere in sight. He then looked at TenTen who seemed to be deep in thought. Well, TenTen did seem to already know Naruto as friend back at the parent teacher meeting… maybe this could work.
"Naruto, you shouldn't go out with Sai."
Naruto glanced up at Sasuke.
"Why?" he already knew why, but he needed to pretend Sai and him were a couple.
"WHY!?" TenTen yelled annoyed. "You're seriously gonna ask WHY!? I can list a thousand reasons why!"
"Oh? And what would they be?"
Everyone then turned around to see Sai, standing there with that fake smile of his. TenTen twitch.
"Well for starters, that smile of yours is fake."
Sai tilted his head in confusion.
"I don't see how that's a reason why he shouldn't go out with me." TenTen clutched her fists. She wanted to kill this guy. Sai then headed over towards Naruto. "I thought you said we we're meeting at the front gate?"
"… sorry."
"That's okay-" he commented as he wrapped his arm around his neck and kissed him on the cheek "just so longs we're together then that's okay."
Sasuke began grinding his teeth. Ooooh how he hated this guy, even more so then that damn Kyuubi guy. Sasuke then had an epiphany, did Kyuubi know this guy? No, certainly not. He would have been dead by now. … Sasuke smirked.
"So, when are you gonna tell Kyuubi?"
"Tonight." Sai commented happily "Naruto said that it was about time he introduced me to the family." Welp, there went all of Sasuke's confidence. "Come on honey, let's go." And with that started walking off.

"…I'm sorry." TenTen commented as she rested her hand on Sasuke's shoulder as he continued to watch them walk off into the sunset. It was something pulled right out of a Goddamned romance novel! Sasuke shook his head.
"It's not your fault." He then took out his phone. "It's hers."
And began dialing Naruko's phone number. As he was waiting for her to pick up he then notice Naruto and Sai had stopped walking. Naruto took out his phone, looked at the caller I.D and panicky turned it off. Sasuke then noticed that the person at the other end of the line had hung up at the exact same time. Sasuke's eyes widened as he looked at his phone then back at Naruto who had just walked past a corner with Sai.

"…Uh, TenTen do you know why Naruto would have Naruko's phone?"
TenTen sighed "Same reason they wear the same clothes."
And with that TenTen walked off. Sasuke then noticed that the two of them WERE wearing the same cloths. …but to have the same phone too?

-

"… Sai I got ta ask, why are you doing this?"
Sai stopped and turned to look at Naruto.
"Because I thought it would be fun."
Naruto rolled his eyes.
"No shit."
"How often do you get to meet someone who has the ability to change genders?"
"More like cursed."
"Same thing."
"No it is not!"
"Wait. What-?"
Naruto jolted and turned around slowly.
"S-Sasuke?"
"You change genders?"
"Ohps, looks like the cats out of the bag."
"W-well-"
"That you were Naruko this whole time?"
"…yes."
There was silence.
"Why didn't you tell me?"
"I didn't want to hurt your feelings…"
"SO GOING OUT WITH SOMEONE ELSE WOULD MAKE ME FEEL BETTER!?"
"Yeah that's what TenTen said too…"
"Ten-? Oooh." Sasuke then realized what TenTen had done. She was trying to nudge him this whole time. He must have looked like such an idiot. Sasuke then sighed and took Naruto's hand. "come on."
"Wha-? Where?"
"Where else? Away from him."
"Owch."
Sasuke then dragged Naruto away and Sai sighed.
"You meant for this to happen…didn't you?"
TenTen asked as she walked up to him.
"Yeah."
"…you really are a prick."
"Yep."

-

Sasuke dragged Naruto all across town, never once letting go even when Naruto began squirming.
"I said I was sorry you god damn teme, now let me go!"
Sasuke did, only to wrap his arms around him. Naruto blushed.
"T-teme-!"
"I'm not letting you go. Not now-" he then lifted Naruto's chin "not ever." He then planted a kiss on him. Naruto was about to protest but… he lowered his eyelids, this felt…right. He then wrapped his arms around Sasuke and kissed back. Things were starting to look good. He wasn't Sai's boyfriend anymore, Sasuke knew his secret and was okay with it and even became his boyfriend! ….Waaaait…. Naruto then pulled away from the kiss. Sasuke looked at him confusingly.
"What?"
"We still have to tell Kyuubi about this."
"….. Ah f-!"
