-This was a bad idea- Kakashi mutters under his breath for the thousandth time this evening without taking his eyes from the sight in front of him, his body almost hidden by the curtains of his room. For different reasons at the time he knew that having Sakura as a neighbour was a bad idea, she takes her job too seriously, she is too diligent, and living in the apartment building across Kakashi gives her an access to check on him whenever she desires or she gets tired of him dodging the hospital.
He should have moved out to the Hokage residence but the prospect of having to move out of the comfort of his old flat for the bare minimum of time until he could pass the hat onto Naruto was too much of a bother for him. For what? For having to look for another home after his retirement, it was easier this way he thought. But then Sakura had to announce that she was ready to move out of her parents home, tired of her mother's complaints about her ungodly hours of arrival due to the hospital or any mission, and that she was going to live in front of him.
The first peek was a complete accident, he had arrived earlier than expected at home, excited to have some time to spare for once and looking forward to re-read his favourite book saga one more time, he walked to the curtains with the intention of drawing them open to let some of the evening light on when he first saw it.
Sakura.
Only wearing her underwear.
Sakura was only wearing her black underwear at her home. He averted his gaze as soon as he realized who he was looking at. Granted that time was a mistake, but it made him confront the vision he had of Sakura with the reality, in his mind she was still this smartass scrawny twelve year old with her merry go lucky attitude and air of innocence that only a sheltered home live could provide, he was aware that she had become a powerhouse on her own thanks to the hours of effort and training under Tsunade, her determination growing with every single day, that Sakura had turned into a workaholic that fixed wounds and gashes because even the most difficult one was easier than the most simple relationship. But yet some naivety still was associated with her, her job in the hospital tying her to the village most of the time was acting as a safe haven protecting her from some of the most gruesome parts of their job. So when instead of that scrawny twelve year old what his gaze met was the figure of a grown woman walking comfortably in underwear in her own house that changed everything for him.
The picture of her walking like that started haunting his dreams, instead of the regular pair of underwear she had been sporting, his dreams turned her attire on a sexier version of it, the color persisted a contrast with her pale skin beckoning him to keep staring.
If the situation was bad enough as it was, then it happened for a second time. A summer storm hitted Konoha one night, he rose from his bed were he was trying to sleep to close the window to avoid the water outside sliding inside his home, and there she was doing the same thing, except her window still was fully illuminated and he saw that she was only wearing a thin white tank top and the bottom half her underwear of a light blue color, it was a fleeting moment and he was sure she didn’t saw him stare, but he was sure as well that the vision had embedded itself on his brain even if he had no sharingan anymore. Now everytime he closed his eyes he could see her, how the tank top clinged to her skin, and how cute her ass looked when she turned around, it make him wonder if her skin would feel as softer under his hands as his dreams make him believe, how it would be to have her pressed against his body, writhing beneath him.
And the torture kept going on because these “accidents” kept happening, they always featured her on a state of underdress but never completely bare to his eyes. After a while he had to admit to himself they stopped being accidents, and he started deliberately looking to her window looking for more glimpses of her to feed his fantasies. One day Kakashi muses that he was sure that this was the way of the universe to get back to him, to punish him for his sins, for all the lives he took, for not being able to save his sensei, for failing Rin, for not noticing that Obito didn’t die until he brought war to their home, for reading romance novels sprinkled with poor smut that were written by the perverted sannin in public, for all of that, the universe now has stripped all the innocent affection he held for his former student and has replaced it with an intense lust for her.
It was after one particular steamy dream and washing the remnants of it in the shower and feeling more dirty than usual, Kakashi resolved to avoid looking through his window from that moment onwards, and to avoid her as much as possible. Every day became worse than the previous one, he grew restless, he prolonged his time in his office, anything to avoid coming back to his home where his curtains constantly taunt him, Kakashi becomes more distracted with each day, his brain craving for another forbidden look, and that in turn irritates him to no end, she has managed to strip him out of all control over his life. He manages to last an entire week, until his resolve crumbles thanks to Sakura herself, she drops by his office late at night, after a concerned Shikamaru mentioned his now seemingly erratic behaviour to her. Deep down, Kakashi knows that Shikamaru meant well, but after having her so close, her warm hand on his forehead checking for signs of fever, her alluring perfume and that stupid red blouse allowing him to take a peek at her cleavage and making him aware that he miscalculated, and her chest seems to be bigger to what he thought it to be in the distance.
Sakura ends up concluding he is only behaving like this due to a severe lack of sleep, completely unaware of being the cause of said lack of rest. She grabs him by the arm, and forces to leave the office, not trusting him to follow her medical advice and wanting to make sure he reaches his home to do as she says. When they reach his doorstep, she waves him goodbye with a smile and walks to the building in front.
So now he is here, partially hidden by his curtains, patiently waiting for her to come out of her bathroom after taking a shower, like a druggie waiting for his next fix, breathing uneven pants growing tighter by the second, and completely ignorant of the mirror in her room pointing to his own room.
