A/N (Author's Note): So, I was reading through the Hyuga Clan's page on Narutopedia when I came across a bit of trivia. According to Kishimoto, if a Sharingan user and a Byakugan user were to have a child, that child would have one of each. The other piece of info that created this idea was Itachi saying that he had a lover at some point, a plot-point Kishimoto seemed to forget about. In this story, this lover is given an identity, and they have a child together. Of course, Itachi is older in this universe, and Hinata has an older sister, but aside from that, those are my only two initial changes: an increase in Itachi's age and a new character. I've thought about this idea for a long time, and my fanfiction-writing skills are super fucking rusty, but I think I've got what it takes to pull this off.

Wish me luck,

PS: Also, this chapter is much shorter than what the future chapters will be like, because this is just set-up.

Itachi Uchiha was a conservative man. Not in terms of political views, simply in the way he did things. His mannerisms and behaviors. He dressed conservatively when he was not on duty, he spoke conservatively, he walked conservatively, he even ate conservatively. He also did everything on a specific routine. He would wake up, eat, go to work, come home, visit with Sasuke for a while, then go to sleep. He would wake up to the same ceiling, the same bedsheets, and the same nobody every morning.

Every morning, except this morning.

This morning was different. This morning, he woke up to a far-larger bed than he was used to, in a far more luxurious room than he was accustomed to. His head was throbbing something fierce, too. It didn't feel like the aftereffects of poison, nor did it feel like an overuse of the Mangekyo Sharingan. He also noticed that he was wearing no clothing. He never slept in the nude.

This was very strange.

Even stranger was the hand on his left pectoral muscle. It wasn't his.

Said hand was attached to an arm, and the arm to a shoulder, and the shoulder to a woman.

A naked woman.

Itachi's cheeks turned the color of his Sharingan as blood trickled from his nose.

She was gorgeous, no question there. Long, wavy purple hair. Flawless alabaster skin. A well-endowed chest and, if the curvature of the blankets were to be believed, wide, child-bearing hips. Her face was soft and somewhat rounded. She smiled in her sleep.

She was practically everything he had every wanted from a woman in terms of physical appearance.

What he was wondering, however, was who this woman was, how they got here, why they were here, and exactly where here was.

The woman that had attached herself to Itachi stirred, lazily opening her eyes.

Itachi found himself staring back into two pale lavender Byakugan.

A Hyuga woman.

Uh oh.

She yawned, squeezing his muscular chest. "Good morning, Itachi. Sleep well?"

Her voice was gorgeous. He couldn't quite explain why he liked it so much, but he just did. Her voice dragged her name from his subconscious: Himawari. Sunflower.

She kissed his shoulder before scrunching up her forehead.. "Ugh, my head hurts like crazy. I can only imagine how you feel."

At the mention of his probably-a-hangover, his head pulsed. He felt like he was going to vomit.

He groaned, rolling over onto his left side, nearly smacking into Himawari.

She got a good look at his face then. his skin was pale and clammy, and he looked to be in extreme discomfort. She felt his forehead. "Oh, you look awful, and you're really clammy. Here, this should help."

She extended out her forefinger and middle-finger and tapped his forehead, injecting a large dose of chakra into one of the tenketsu connected to his brain. He instantly felt revitalized and the pain in his everywhere melted away.

She giggled. "Looks like that worked. You should see the look on your face."

He turned red.

She pursed her lips"Oh please, it's not any goofier-looking than that face you made when you climaxed."

He turned even brighter red.

She kissed his nose. "Relax. I was the only one who saw, and I think it was adorable."

In an instant, it all came flooding back. Them meeting in the Hot Springs, the trip to Tanzaku Town, the gambling, the drinking, then, finally, here. They had had so much fun together, and with her Byakugan and his Sharingan, they had really cleaned up. Unfortunately, he also remembered his face when he reached climax.

This was not his first time with a woman, but it was his first time with a woman that he had engaged in by choice. He had seduced multiple enemy kunoichi on orders from the Hokage for information to aid the ANBU and Konoha. It wasn't like he hadn't enjoyed his time with those kunoichi (especially those from Kumogakure), but that was purely physical. While his union with Himawari was likely founded in alcohol, he did feel a legitimate emotional connection with this woman. He felt likeugvpserngvesiunhgbvreiodovfidnl-

Himawari scrambled his thoughts with a kiss.

"You still in there? You just started staring off into space for a minute there."

He nodded.

She tapped his nose. Her fingernails were painted purple."You're quiet when you're sober."

Another nod, this one accompanied by a small chuckle.

"You're not when you're drunk, though."

A terrible thought struck Itachi like a lightning bolt."Did I say anything that sounded like it might have been classified information?"

She shrugged. "I don't know. I think past a certain point, everyone in Tanzaku Town gets drunk. Even if you did reveal something, I'm quite certain people are too busy trying to fight off a migraine to care about classified ANBU intelligence."

He sighed, relieved.

Itachi stood up out of bed and looked around. This was definitely one of those places where strangers would meet and hook up. What did his father say they were called? Love hotels? That was it.

For being a love hotel, it was still equipped with what one might use to engage in activities that weren't sex (desk, fridge, coffee table, shower, etc), which was something he appreciated.

He searched for his clothing. He found it.

Himawari heard a loud, pained groan come from Itachi's direction.

"You alright?" She asked, concerned enough to worry but not enough to aim her question in Itachi's direction.

"Yes, but my clothing isn't. Did you have to shred it this badly?"

She smiled wickedly, cackling mischievously. "It was in my way."

She heard footsteps over to the dresser. Then he spoke again. "I'd like to point out that your clothing is folded neatly and stowed in the dresser."

She sat up, baring her chest."You fail to realize that you're the only man in Konoha who's considerate enough to fold a lady's clothing for her."

He had enough decency to look away. "I can't be the only one."

She did not have the decency to look away. She stared straight at his crotch.

Itachi noticed and turned red in the face once more. He used the shredded remains of his mesh shirt in a feeble attempt to cover himself.

She licked her lips."You cock's too long to cover with that, Itachi. Even if it was, I could still see through it. I spent most of yesterday looking through your clothes."

He shifted awkwardly. Goddamn Byakugan.

Itachi walked over to the bathroom to shower.

Himawari rolled over towards the bathroom door. "Hey, all my friends talk about their boyfriends constantly trying to get in their pants. Ironic that when I finally shack up with a guy, he just so happens to be the most polite, well-mannered man in the world."

Himawari sat up and stretched, yawning. "What is it about women that they like jerks? Even I like jerks sometimes. I hate it."

Even over the loud pitter-patter of the shower, which was not inconsiderably loud, Itachi heard her well enough to respond. He raised his voice out of his usual breathy deadpan. "It's a confidence thing. Most men don't know how to display confidence and dominance in a subtle way, so they think the best way to display dominance over others is to degrade them. That can work if it's done with sufficient social precision and tact. It's more consistently useful to exude a sort of quiet confidence, though it's harder to pull off."

Himawari stood up out of bed, mischief on her mind. She activated her Byakugan and crept into the bathroom. "Oh? How would one do that?"

Itachi, eager to conversationally discuss the human mind with someone and having closed his eyes to wash his hair, didn't notice Himawari creeping up on him."Body language is a big part of it. Standing up straight with your shoulders back and legs pointed straight forward. Consistent eye contact is important as well, though too much can give people the impression that you're either threatening them or flirting with them. You should also remember-"

Itachi opened his eyes and saw Himawari step into the shower with him.

Blood dripped from Itachi's nose.

She smiled mischievously. "You should really get your nose checked. Might have a bleeding disorder."

His face contorted in a mixture of frustration, amusement, and very poorly concealed arousal. This woman was wonderfully annoying.
