Because of You

I.

 

Kakashi would never admit it, but he was in love. 

Undeniably, sick in love.

He couldn’t say who, and never out loud. 

 

So when he rolled over in bed and stared down at the naked woman in his arms soundly asleep, his chest burst happily with a warmth that he hadn’t experienced in his entire life. The morning light bled through the blinds, and she looked up at him through thick lashes — the events of their night flashing through pretty jade eyes. 

For someone that put love and relationships at the very end of his priorities list, it stumped him how it happened.

 

 It probably started when she almost died for him.

Or when he entered the hospital to see here in a coma, tubes and ventilators the only thing keeping her alive.

Or when he first met her at the steps in front of the academy, bright eyed, cheery and with a smile that lit up the entire yard.

Or when he first saw her on a date with that damn Uchiha, and a year later caught her crying to herself in her office at the hospital — heart broken but still upbeat to see him.

Or probably, most likely it was every year when she accompanied him to visit his father’s grave — bringing flowers and silence, both which were sincerely appreciated.

 

None of that mattered, because he loved her. 

Kakashi loved his Sensei, someone he shouldn’t love — but a simple crush that began with her bravery, heroism, and decimating power that first left him in awe quickly catapulted his feelings into full blown love. As he grew, and as their team gathered more memories, he knew and hoped it would go away.

It didn’t.

 

Each day for training when their muscles would be spasming from exertion, she would push them to go further. When they went on a mission to escort Tazuna in the Land of Waves, and she was able to defeat the Demon of the Hidden Mist, it nearly exhausted her and she had to activate her seal, but she beat him. Somehow, she still managed to save them from Haku after he left Rin and Obito incapacitated. It was in her last ditch effort to save him as Kakashi lie on the ground. He had left himself with no chakra left trying to save Rin and Obito, and in the process almost lost his eye. Blinded and fearing the worst, he didn’t notice Haku readying to kill him. With a speed he didn’t think was human, she completely covered him with her body and took hundreds of ice picks to the back. Her blood covered him, and he would never forget the wavering smile telling him everything would be ok, they all would be ok.

 

If it weren’t for her byakugou, he was sure she would have died.

 

And he felt so useless. How could he become a great shinobi like his father if he couldn’t even keep his team safe? What was the praise everyone gave him if he almost witnessed his Sensei who he admired and respected more than anyone nearly died because of him?

 

No.

 

So he trained, trained harder than the rest of his class — asked Sakura to train him, asked Sasuke Uchiha to train him, of all people. It would never happen again. People noticed his strengths, people noticed him pushing his body over the edge, but the trauma and pain from their missions and need to surpass everyone, to hide from the pain of losing his father was enough to drive him far.

 

“Kakashi…I think you’re pushing yourself too much, do you need to talk?” Sakura placed a gentle hand on the top of his head to focus his eyes on her.

Even amidst his anger after another mission went awry, he couldn’t direct his anger towards her. He slumped, like the gravitational pull of the earth released and all of the pressure melted off of him and he leaned into her hand. 

Sakura retracted her hand with a frown, knowing he was hurting.

“That mission…It wasn’t your fault. I know you carry that burden, but don’t let it. I should have been more alert, I should have expected something like that to happen. I’m the reason that you almost…” she paused to clear her throat, “lost your eye. And I’m so sorry.”

“No,” he reeled, voice thick, “you do everything you can for us, Sakura-sensei. You train us individually, you take us to eat, you’ve been there and helped me process my father passing, you make Obito feel welcome , and you’ve made Rin one of the best kunoichi in our class, don’t say sorry.”

He never expressed this much emotion, and she gingerly tucked a stray lock of her hair behind her ear, a rueful smile on her face, “thank you, that means a lot to me.” Another pause, like she was chewing on what to say. “—I wish I could protect you all from the kind of world we’re in…Just, you don’t have to bear all of our pain on your shoulders alone, ok? We’re a team!” 

 

He figured that she learned that from Naruto — the other guy he rather not speak of. The guy that blatantly flirted with his sensei and tried for years to get her to go out with him. She never accepted though, so there was that. Back then, he knew that the jinchuuriki residing in Naruto destroyed the village and he was outcasted, but from the looks of how jovial and loud her former teammate could be, Kakashi couldn’t imagine the pain his sensei’s team must have gone through so long ago.

Hands stuffed in his pocket, he was passing by Ichikaru when he spotted his sensei and her former teammates at the stall, happily talking with one another. The Uchiha wore his standard police outfit, and Naruto kept leaning in a little too close to his sensei. 

A pit of jealousy rose in his stomach, and he stopped in his tracks to glare into the backs of two of the strongest shinobi in their village.

 

“Maa maa, you can just feed me Sakura-chan!” 

She pushed him with her arm, scowl on her face that didn't meet her eyes and a small laugh in her chest.  Kakashi flailed, because he could see the jealousy in the Uchiha’s eyes next to them. 

“Oi, Sakura-sensei!” Kakashi ran up to the trio who all turned to look at him, and the look on Naruto’s face was priceless.

They didn’t get along, only because Kakashi always interrupted and stopped any and all attempts for the jinchuuriki to hit on his sensei. “Can I eat with you, Sensei?” He feigned his happy face, eye crinkling hopefully above his mask.

Sakura smiled and made room at the booth, forcefully moving Naruto out of the way, “of course! What are you doing over here?” 

He muscled himself between the blond and his sensei, casting Naruto a triumphant look that made the loudmouth glare at him, “every time I try and get close to Sakura-chan you always manage to show up!” 

“Naruto!” Sakura snapped, “don’t talk to my student like that!” 

“B-But he does! It’s not my fault he has a crush on y—Ow!” 

Pakkun, only just a puppy and summoned at Kakashi’s command bit Naruto’s leg rather lazily, but enough to make him yelp.

“What the—“

“I was in the neighborhood,” Kakashi mused, his unsuspecting sensei none the wiser to what he was up to. Sasuke rolled his eyes and focused on his meal, clearly on the same page as Naruto, but much quieter about it, “—and I was hoping that maybe we could have a sparring session today?” 

Swallowing her food, Sakura mentally checked off her to do list and obliged happily, “mm, yes! I just have to turn in some forms to Tsunade-sama, but after I can meet you at the training fields.”

Naruto hmphed!  unhappily next to the chuunin, grumbling about stray dogs and always having this kid interrupt his dates. 

 

And just like that, his day was successful.

 

Years later, his world nearly crumbled when he found out about the candid relationship between Sasuke Uchiha and his sensei. It killed him on the inside, only because he knew how much his sensei actually loved the man. It sickened him.

He was nothing special, just another Uchiha. 

It was after the Great Shinobi War that they started dating. 

 

They went to travel with one another, accomplishing missions from afar. At the time, Kakashi was seventeen and he wanted nothing more than to see his sensei again. As a jonin himself now, he was always away on costly missions. Once he joined ANBU and they still weren’t back, Kakashi had lost hope.

But they returned, seemingly happy.

 

They broke up half a year later.

 

One day after he was finished being patched up at the hospital after an especially grueling mission, he went to stop by and say hi to the pinkette. From outside the door he could hear her sniffles and debated on entering, but he knocked anyway. The simmering rage he felt towards the Uchiha was enough to make him want to seek him out and ask him why he wouldn’t go to the ends of the earth to keep someone like her in their life. 

Ungrateful.

 

She tried to hide her tears, but her nose was tinged a bright pink and her tears were fresh on her cheeks. 

She’s so beautiful, even when she cries.

 

“Oh, Kakashi — I didn’t know you were back from your mission. Hi,” she tried to fix herself lamely and hid her face to look away from him.

“I-I’m sorry, you shouldn’t see me like this.”

He stayed quiet, and she fumbled on what to say.

 

“Do you need help with anything? Did you need to ta-“

“…He didn’t deserve you.”

The statement was concise and prompt, but he meant it. Hands stuffed in his pockets, he leaned against the door frame. He towered over her now, and his body leaned out — when was the last time she had seen him? Almost a year and a half ago?

With age she got even more beautiful, her curves were filled out, her hair was long and tied into a low ponytail, and the light dusting of make up on her lips and eyes made her face sparkle. 

“Excuse me?” She murmured, looking up at him fully now. 

“He didn’t deserve you, you’re too good for him — I hope you know that.”

A flush rose to her cheeks and she waved him off, awkwardly laughing through her tears, “you don’t have to be nice to me because I’m your sensei.”

He took a step forward, heart palpitating in his throat, “its true. You’re one of the most intelligent and kind women I’ve ever met. You’re beautiful, compassionate—” Now he felt like he sounded akin to a petulant child, but she brushed off his praise.

“Your girlfriend wouldn’t want you calling another woman beautiful—“

“I don’t have a girlfriend,” his tone dropped so harshly Sakura nearly winced, but she blinked at him…And a pepper of realization dawned on her. 

“Kakashi…” she warned when she noticed him take another step towards her. Yes, she was ten years his senior, but he wanted her to know how much he cared for her, how much he respected her. It was now or never.

“I love you, I always have.” His eyes were hidden away by his mop of hair, and his voice shook with the intensity of his words, “and I think I always—“

“Stop!” She stood and slammed her hands on the table, cracking the wood and sending a small jolt within the room from the intensity of her strength, “please, Kakashi — no. You’re my student, and you’ll always be my student. There’s so many girls your age—“

“I don’t want anyone else, Sensei!” He clenched his hands, it felt like a spear lodged itself through his heart. His chest hurt, and he knew now that he would regret everything in this life if he didn’t make her understand.

“No one compares to you, I don’t want another girl — I want you.”

 

Her anger simmered, and she stared at him — searching his face for any sense of insincerity. She knew him better than that, and knew that he would never make a proclamation like this if he didn’t mean it. Sure, he had slept with girls by now, and midway through their departure from the village, he tried his hand at a relationship.

It wasn’t for him.

It was her or no one else.

 

 

And just like when it was him, Obito, and Rin — she tilted her head in sympathy. A small smile edged her face, and she walked over to him. 

Something he’ll never forget in his life, and it burned itself in his memory forever — she placed chaste kiss on his forehead and set her hand lovingly on the top of his head, “I…Need some time to myself.” 

 

She left him in her office, alone and blindsided by her actions.

 

After that, the world resumed like nothing happened. She would wave happily at him whenever he needed to be fixed up at the hospital, he would read his Icha Icha in public — but their paths never really crossed these days. He requested every long distance mission he could that would send him away for months at a time. With a success and safety rate like his, his name was up there in the ranks with Naruto and Sasuke.

He didn’t care, not really.

 

Years passed and he would sleep with different women, tactfully avoiding the hospital whenever he could. He gave heartfelt attempts at relationships, but after some time and that feeling of excitement and love that was supposed to be the foundation for any relationship never appeared with any of his previous relationships. It wasn’t fair to them, so he gave up. They deserve more than a shinobi that preferred to read porn and was in love with his teacher.

Rin would try to invite their team out to keep them together, but he retreated into himself. Obito and Rin started dating, and he had to admit that it was about time -- they were a good pair, and Obito loved Rin longer than he loved their sensei. It wasn’t that he was devastated about his rejection, he just knew that there wasn’t going to be someone else that he truthfully loved like he did her. 

So best to respect her wishes and carry on with life. 

Except it would eat him alive, this self induced torture of distancing himself from her. And every year when he would visit his father’s grave, there would be the same bouquet of flowers that Sakura would bring when they would go together.

After everything and tactfully avoiding her — she still showed up. 

 

On the eve of his twenty second birthday, he was assigned to ANBU permanently. 

And low and behold, annoying can’ttakenoforananswer Naruto who somehow became Hokage assigned him to escort Sakura to the land of waves. A virus was wiping out children, and before it could spread they needed the best medics within the fire nation to eradicate it and come up with a cure. Sakura was known as one of the best, and if this was something curated by man and used as a weapon, there would be a hunt for any and all talented doctors. 

 

Which left him walking next to the woman that he pined after for so long.

A wall of silence stood between them, and it was her that broke the familiar silence, “sorry you have to be paired with me,” she mused off-handedly, gripping her backpack with a small smile, “I know you probably wouldn’t want to take this mission.”

He took a while to respond, but finally ushered, “…I don’t mind it, it brings back memories.”

In reference to when she almost died protecting him, Sakura looked up towards the sky to appreciate the spring leaves and thick clouds that rolled by them, “congratulations on your permanent position in ANBU,  by the way. I know Rin wanted us all to celebrate, but you were out on a mission.”

He shrugged his shoulders, stealing a glance at her. His throat dried a little.  “It’s nothing, I’ve been trained by the best, no?” 

His single eye crinkled, but it was fake.

“Don’t do that,” she scolded him, “I know you better than you think even after all these years. You can be mad at me, but don’t fake being happy — not with me, ok?”

It was part of his healing process to take on tidbits of personality from the people within his life. He noticed it with his father, and then when he fed off of Obito and Rin, and he couldn’t understand why he was like this. A therapist once told him it was a trauma response to their line of work and his father’s suicide. 

“Ok,” he seceded, he really couldn’t ever be mad at her, so in the sting of his rejection — he retreated. 

Four years later and his feelings remained the same. “—I want to apologize for putting that on you so suddenly.” This ate him alive more than the actual rejection, “It wasn’t right. I was being selfish.”

Sakura stopped, surprised by the sudden admission and she tilted her head to get a good look at him, even with his mask it always felt like it was translucent in her presence, “…I really appreciate that. Thank you.”

The tension eased between them, and she nudged his shoulder with her own, “it was a very nice compliment, though. It’s nice to know I still got it.” She grinned up at him, hands behind her back so she could peer at him with a wink. 

This was her.

 

Undeniably cute, but he would never admit that.

 

His cheeks warmed up, and he looked away pointedly, “we should focus on the mission.”

Sakura pouted, but visibly relaxed around him, “who’s the superior here? I never thought one of my students would grow up and boss me around.” 

 

Their trek to the Land of Waves was tremulous, and they passed the bridge that brought back an onslaught of memories. He noticed that his sensei visibly dimmed when they crossed it, but perked up once they made it to the village. Hundreds of people came here for the thriving tourism, and there were no established shinobi, so they received a lot of curious looks as to why they were here.

Once they talked to the council that requested Sakura, they brought them to the briefing.

It was all business from there.

 

Sakura worked tirelessly once they reached the clinic with the isolated children. He stayed stationed near her at all times, and kept a watchful eye. Something…Wasn’t right. Kakashi kept his focus on her, and by the time dusk was approaching the horizon line of the beach, he noticed his sensei pop a soldier pill and continue on.

It wasn’t until midnight that Sakura decided to call it a night and they went to their temporary residence.

Which was one home, closer to a nice hut pressed against the hillside along the beach. They really treated her like royalty, which wasn’t that far off considering she was one of the nation’s best medical nins and director of multiple hospitals in different villages.

Her resume didn’t end.

 

Still, why they gave them one room made him nervous.

Alone…With his sensei…Who had just showered and was prancing around in her nightgown.

 

Sakura stretched her arms high above her head and looked out of the window, they could hear the gentle rolling waves splash against the beach, “it’s so beautiful here. I wish we were here on vacation and under better circumstances.”

If it hadn’t been for him telling her she needed to take care of herself, she wouldn’t have pulled away from the mountainous pile of documentation, scouring the history of the illness and symptoms.

Now her hair was tumbled down her shoulders, and the thin nightgown she wore cut off high on her thigh. He sat finishing his dinner, and she brought her knees up to her chest — which caused her nightgown to rise, it pained him that he was behind her. Still. He risked a look at the creamy skin of her thighs, and the subtle glow of the moon caressed her skin.

 

Why me?

 

She turned back to look at him, “sorry we have to share a room, maybe tomorrow I can ask them for another—“

He coughed low in his chest to cut her off, “no, it’s better for me to be closer to you.” As happy as the village seemed, he couldn’t shake the sense that this went a lot deeper than the mission primarily assumed. All those years ago he promised himself nothing would ever happen to her again if he could prevent it, and he intended to keep that promise.

Besides, this situation was something that he read about in his Icha Icha books, and in his fantasy world he could live out one of the plots.

She stood up and procured a pretty smile for him, “you can go ahead and shower now. We should both get some rest.” Passing by him, he got a whiff of her scent— kami, cherry blossoms. Sakura hummed, and she went to get some water, bending down — effectively hiking up her dress.

His mouth dried.

Her panties were in full view, simple and white — but lined her cunt perfectly and he almost forgot to swallow his bite of food. — She’s doing this on purpose.

 

There was no way that she could strut around and think she wasn’t teasing him.

But why?

 

He felt his cock twitch, and he adjusted himself in his seat.

When she turned to look back and say something to him, Kakashi disappeared into the restroom to wash up. He missed the small smirk on her face. 

 

By the time he came out, Sakura was already in her mat. The steady rate of her breathing alerted him that she was probably asleep. He walked by her, shirt off and pants hung low on his lips. He did a quick pace around the room to secure the house, unaware of the shimmering eyes watching his lean body. Part of him knew she was awake when he came into her view — his keen ears noted the way her breath hitched momentarily, and he faced her only to see her feigning sleep.

So this is on purpose.

 

So he sat in the chair across from her, whipping out Icha Icha and deciding to stay awake and keep watch for a while longer until she really fell asleep.

When he knew she was asleep, he made it to his mat.

They were so close, and her back was towards him, and he wanted nothing more than to pull her by her waist so she could be snug against him.

Instead, he reached and touched a single strand of her hair. 

 

Weeks passed with the new game they were playing. During the day, Sakura focused on creating a cure for the acute respiratory illness that was killing the children. Since she had gotten here with a couple other notable doctors, they had kept the children alive. It was hard, and he could see the stress ebbing at her because she couldn’t take their pain away. By the second week she was close to creating a cure. 

By week three it was figured out that this was a man-made illness, so now the unleveling to the mystery was who created it.

By week four, nearly all the children were rid of the illness. All other children within the village that had been exposed were quarantined and given a vaccine. Within a month, Sakura and her team eradicated the illness, created a vaccine, and managed to stop the spread of the virus — but the bigger problem arose. Her name was said throughout the village, and whoever wanted this illness to spread would surely get news of it soon. The parents and people within the village were grateful to her, showering her with gifts and praise. She quickly became a local legend, and she had numerous offers for her to stay — a hefty salary for a permanent residency was offered, but she politely declined — her heart would always be with Konoha.

It kept Kakashi on his toes. 

 

It sickened him when the men would adamantly stare at her, in awe of her beauty.

A famous actor taking his time to travel through the village heard of her and sought her out to ask her on a date. Although slightly flustered, she also declined — and he would be a liar to say that part of him felt a small amount of satisfaction when he walked away defeated.

 

His favorite part was returning home with her. They established a routine of bringing home dinner, eating together, talking, unpacking her work for the day, and sitting on the balcony appreciating the beautiful scenery. In between all of that, something within the hut would change and draw out his sensei’s coquettish and provocative inclinations. He tried to ignore it, but he couldn’t resist. 

Small touches, the way she would lean over him, and in the past month he had the best view of her. Like tonight, where she was visibly relaxed with her progress and work done here. Her cami was nearly see-through, and the cool air from the beach made her nipples hard, and he tried to keep his eyes level with her face, but the way she was sitting on the couch, staring out at the ocean made him lose his breath. Just to tease her back, he would roam around their makeshift couple's home shirtless. He didn't miss the way that she would steal glances at him and let her eyes linger on his flexing muscles when he would do things around the room and get ready for bed.

“Kakashi,” she murmured, still staring out over the water, “thank you for everything on this trip, you’ve been the best escort.”

He roamed his eyes over her face, her lips looked extra plump today, and his perpetual boner deiced to stir, “you’re welcome, Sakura-sensei.” In a bad habit he developed over their time here, his eyes flicked to her breasts, and she caught him.

A small fire ignited between them.

 

Sakura leaned forward, giving him more of an ample view of her chest — he could clearly see her nipples, and he wanted nothing more than to dote on them and pop one in his mouth. Fuck. This wasn’t fair. Their time here would conclude, and their lives would resume — one without coming home with her every night.

“Kakashi….Were you staring at my breasts?” 

 

Mortified, Kakashi looked at her, and she held his gaze. 

Somehow, she transformed from his sensei — to a vixen showered in moonlight.

He stuttered over his words, and as a grown man who was self assured and maybe a bit cocky in his craft, he was left agape in what to say. Her hair hung over her shoulders, and the playful tilt of her lips accentuated how pink they were.

“It’s disrespectful to ignore when a superior is asking you questions,” her tone slightly hardened, and she moved her hair to the side so he could clearly see her ample chest.

Part of him felt like he was in a trance, “I—was.” 

She leaned back in her chair, and he regretted sitting across from here, because her eyes looked down and could see his engorged member outlined through his pants. She tilted her head mischievously, “you’re hard.”

He could only rip away his gaze and sat there, wishing for a quick death. This was embarrassing, and as someone that felt well versed with women sexually, he didn’t know what to do. Kakashi nodded, holding his breath to will his boner away.

“Look at me.”

 

Slowly, torturously — he looked, and the sight before him made his mouth slack open. 

 

Her legs were spread open in front of him, and he realized now she wasn’t wearing anything underneath. Her pussy was on display, pink and bright and so perfect, it made his body lax. She trailed a slender finger down to her thigh, leaned back on her chair with her eyes half-lid.

“Kakashi.”

He gulped and ran a hand obtusely through his hair, “…y-yes, sensei?”

“Do I look good?”

 

Kami, yes.

He would have yelled it to the heavens too if he could get a grip on his vocal chords. He cleared his throat in dissaray, “you look…perfect.” 

Her devilish finger trailed itself between her slit, and she teased him with those goddamn eyes of hers, “we go home in a week, you know that — right?”

Kakashi weakly nodded.

 

“Do you want to fuck me, Kakashi?” 

Who was this woman? This wasn’t the same woman that would get flustered around Sasuke, this wasn’t the same woman that would blush at the drop of a hat. No, this was the woman that commanded a surgical room, commanded an army, could break the earth with her fist, and commanded him.

“Yes,” he whimpered in the back of his throat.

 

“Come here, on your knees — now.” 

He dropped to his knees instantly, faster than when the Hokage would summon him. On his knees, he couldn’t pull his eyes away from her beautiful cunt. It glistened, and the way her finger traced around her puffy nether lips made his groin painfully tight. 

He always imagined if her hair was pink down there too, and he was right. 

Mmm, stay there —“ she stretched out her leg and put her big toe on his forehead, stopping him from coming closer. He didn’t care that her tone dropped almost condescendingly sweet, he didn’t care that he felt like a puppy, because he was so close to her. 

He wasn’t embarrassed by the pathetic noises he was making. 

Someone could probably see them from down below by the beach, but the thick brush and trees that covered their balcony slightly obscured them from view. A sick, deep part of him wanted people to see. Wanted people to see that he was chosen. Not anyone else, him. 

The way her foot flexed made his mouth water, and he was caught on his hands and knees.

For how pathetic he felt, he was fucking turned on.

This was a dream, better than any Icha Icha — even the new releases. 

 

“How many women have you been with?” she murmured, slowly dipping her middle finger into her cunt. 

Mouth slack, he couldn’t gather the right words. They weren’t computing in his head, “—what?” 

He shifted slightly, she glared at him and started to close her legs, “I said, stay there.” He wanted to protest, they couldn’t stop here. He would listen. She opened her legs again after a moment and dipped her finger in further, lulling her head back a bit to let out a soft moan, “—how many?”

Kakashi gathered himself, but he was mesmerized, “fifteen.”

 

“Fifteen?” She questioned breathlessly, adding another finger into her cunt. He had prime view of the way her fingers began to work herself, and he wanted to ease the tension in his pants — but he was stuck there by her command alone. Instead he nodded, suddenly feeling suffocated by his mask. “—Have any of them seen your face?”

He shook his head, “no, they haven’t.” 

“Take your mask off for me.”

He would kill for her, if she asked him. 

 

This wouldn’t be the first time she’d seen his face. There were times at the hospital she would need to check him, but she made sure to let him keep his mask on for other nurses and doctors to respect his privacy. It must have been a sense of pride, because when he slowly peeled down the material from his face — she added another finger and moaned his name.

Kami.

He was a goner.

 

Kakashi wasn’t a stranger to the fact that he knew he was attractive. And it was only answered by his sensei looking at him through half lidded eyes. Except now, she removed her fingers and moved her foot, “come.”

 

The ANBU inched forward, closer and closer — scared she might stop this whole thing and expel the genjutsu. His face was inches from her cunt, and she pulled him closer by losing her hand into his hair, “eat me out.”

This couldn’t be real. He wasn’t going to take any chances on ruining this fantasy, so he obeyed her eagerly. Mask pooled at his neck, he ghosted his breath over her slit. Her thighs shivered from the cool night air and his proximity, and he could only look up at her and groan. Pushing her hand aside, he pressed the flat of his tongue against her, licking upwards in one fluid motion. She gripped his hair harder, mewling softly.

His palms squeezed on her thighs and he spread her legs further.  As expected of a kunoichi, her flexibility was unreal. His tongue lapped at her up and down until he used his right hand to lift her hood and reveal her clit. Insatiably, his mouth clamped down. His tongue eagerly swirled around the engorged nub, and Sakura tossed her head back, her arousal sweet on his tongue.

“Yes! Yes! Just like that!” 

Ever one ready to please her, he expertly worked on her clit — taking his time to treasure the moment.

Sakura’s scent, taste, and sound enveloped him. 

He squeezed on her thigh harder, her moans became louder — and he was going to cum from this alone. Never before had he been so turned on. It felt like his pants were stretching with him, and absently he ground against the air to ease the pressure.

She must have noticed, because she cried out his name, eagerly begging for him to continue, “I’m so close, ah! Kakashi!” 

Swirling his tongue around her clit and flicking it — he growled — completely virile and dominant that made her skin crawl with goosebumps.

One long, hard flick with his tongue and she careened off the couch — toes curling and thighs quaking around him, she clenched her thighs around his head, her cry lost against the crashing waves of the sea.

And he lapped it up, every last bit.

She tasted like honey and melon with the barest hint of salt, he continued to lap at her — groaning and moaning hard against her cunt as he stole her juices from her. She was a feast and he was starving. Her orgasm nearly made him buckle, and Kakashi took the extra time to appreciate what he craved for so long.

 

Minutes could have passed by and the strength of her thighs crushing his head almost made him faint, but he didn’t care. When she came to, her breasts heaved and she kept panting — but finally let herself relax, “that…Oh my god,” she murmured breathlessly.

Kakashi removed himself from her, chin wet with her slick, he couldn’t pull his eyes away.  This was all he wanted for the rest of his life. “You taste amazing,” he said, tempted to go back in for seconds.

A fierce blush tipped her nose and cheeks, a small break in her vixen repertoire — it made him smirk. Slowly, and gaining the confidence of a man with the world at his fingertips, he lifted himself to blockade her in her chair. Standing and leaning over her, he caged her in between his arms with his hands placed on either side of her. 

He looked down at her, menacing and dark — but entirely masculine. 

Sakura hummed appreciatively, looking up at him with an innocent face after the high of her orgasm, as if she didn’t just tease him into the most painful erection of his life.

“Kakashi…I want you to kiss me,” she breathed out softly, so soft that he almost missed it. 

His heart leaped, and he couldn’t move. 

 

He could only stare down at her full lips, the pretty slope of her nose, and the eyes that reeled him in. 

“Sensei…” 

If he did this, he would be a man gone. Ruined forever and destined to be an old man reading Icha Icha. It wasn’t fair, not to him. Maybe that baka Naruto rubbed off on him, because he wanted to stupidly run his mouth and ask why. His question could possibly ruin everything, but he had to know.

“…Why now?”

Always one step ahead of him, she gently smiled up at him, bringing her hand to rest on his cheek, “because I’ve realized that life without you isn’t the same. I miss you…” Her voice quivered, it felt like she wanted to cry — he searched her for a lie, but knew she wouldn’t do that to him. “—And I’ve realized that being here with you…Has been the happiest month of my life.”

His chest swelled, like two souls that were fated to meet — he leaned down to place his lips on hers.

Soft at first, both were overwhelmed with the intensity of the moment. Sakura gripped either side of his face, and Kakashi felt like his knees were going to buckle. Like a canon signaling the beginning and end of a festival, their kiss became more bruising. Sakura nipped at his lips, and the ANBU opened his mouth — her tongue ran along his, scavenging his mouth. 

Delicate mewls assaulted his senses, and he lapped at her tongue, her juices still heavy and fresh in his mouth.

He could die happy now.

 

Sakura had other plans, because she used the slightest bit of chakra to maneuver herself over him. Switching their positions, she straddled his lap — never breaking their kiss. She bit on his lower lip, hard. She ground against him, moaning and daring him to go further. His large hands gripped her ass, spreading her cheeks for him so his length could grind against her core.

Pulling away, there was a slick of saliva left between them.

“Kakashi…” she broke, trying to clarify the situation, “if we do this —“

“Will be our secret,” he finished for her, “I don’t care. As long as I’m here with you, the rest of the world can burn.” 

His proclamation made her eyes sparkle, and she leaned down again — her body covertly pressed against his. They ravaged each other’s mouths, lost in the dizzying sounds that they were able to bring out of one another. Kakashi ran his hands up her sides, hesitating fora brief moment before he caressed her breasts. He pulled away from their searing kiss so he could slowly pull down the straps to her cami.

Breasts free, Sakura looked away demurely — shy all of a sudden. Kakashi pressed her for another kiss, using his free hand to grab the nape of her hair and tilt her head back. Trailing down, he showered her neck in sloppy kisses, he suckled on the dip above her clavicle. She didn’t push him away, so he left his mark. 

After a few moments, he pulled away to look at the dark hickey he left and a sense of pride coiled in his chest.

“Kakashi,” she ground against him, nearly bouncing. “I need you,” she whispered.

He forced her to move closer to him and leaned into her ear, “shhh. You’re going to let me take care of you, understand?”

 

Whatever bravado she had in the beginning was gone, because she whimpered in response and he felt the power dynamic switch between them once more. Good. 

Letting go of her hair, he grabbed ahold of her breasts and pressed them together, “you’re perfect,” he breathed before latching onto a nipple. Sakura cried out, murmuring something about her nipples being extra sensitive.

So he bit down.

 

Not too hard, but enough to have her arching her back and steadying herself by grabbing his shoulders. In the time that passed between them over the years, he towered over her — and even sitting atop him he had lean down due to their size difference. His tongue lapped and swirled around  her nipple, his thumb on his right hand swiping over the other bud. 

It sent her into a frenzy because she kept murmuring his name, begging and pleading for him.

 

It was the voices laughing on the beach that made them both freeze. 

 

If they caught them at the right angle, they would see his sensei half naked and him feeding on her breast. Sakura got closer to him, trying to hide her body from their view. “Inside,” she ordered. 

Always a great listener, he unlatched himself from her breast and quickly lifted her up in his arms. Like newlyweds entering their home for the first time, he took her straight to their mats on the floor and gently set her down. 

Sprawled out for him, Sakura’s chest heaved with anticipation, and she trailed her eyes down his magnificent torso until her eyes landed on his crotch. Crawling towards him, she sat on her knees and began to undo his pants. Mesmerized herself, his erection sprang free — only held down by his suffocating briefs. Carefully, she peeled down the tight material until they pooled at his feet. He stepped out of them and looked down at his gorgeous sensei on her knees for him.

Kakashi gulped, afraid this was all a dream.

He pushed her pink hair away from her face, and she leaned effortlessly into his touch. Caressing her cheek, they were in a trance — closing her eyes, Kakashi ran his thumb over her bottom lip, wondering how it came to be that he would be graced with her like this. Sakura popped her mouth around his thumb, looking up at him with lust in her eyes.

His groin tightened painfully.

 

Sakura possessed him.

 

When she wrapped her mouth around him, Kakashi leaned his head back, “fuck.”

Eyes closed, Sakura moaned around his length and took the entirety of him into the back of her throat. Part of him wondered if she did this often, or if she learned all of this from that damn Uchiha…but he couldn’t even think with the way she worked her mouth on his length. 

Her tongue deliciously teased his engorged head, and he groaned hard and low in his chest. It felt like he was going to cum already.

“Sakura-sens—“ he bit out, fixing her hair to get out of her face. Her throaty moans vibrated around his cock, and his balls tightened. “Sakura…!”

Taking him completely in one long motion, she gagged on his member — once, twice, three times and he felt his world crumble around him. He gripped her head and fucked into her mouth, his loud moan escaping into the night. Oh fuck, oh fuck. “Saku-!”

She pressed her nose to the silver curls on his crotch and drank from him.  His balls seized and the hardest orgasm of his life made his body tense. 

Greedily, she swallowed his cum in stride, moaning headily around his member and reaching between her legs to play with her clit. 

He wanted to collapse, and when she pulled away to lick her lips and look up at him with that pretty smile, he growled and tackled her to the floor. Already hard again, his sensei slipped completely out of her cami and tossed it to the side, now bare and completely open for him — he took the time to appreciate every facet and curve of her body.

Starting with her feet, he kissed at the soles and licked on her toe — making her giggle and lazily rub her clit for him. Kakashi was known to take his time, and with the patience of a saint — he was going to savor every second of this. Kissing his way up her calf, he kissed around her knee, making appreciative noises as he nipped and bit at her tender skin.

When he reached her slit, he kissed the juncture of her thigh and Sakura tensed, halfway preparing for him to lick at her — but he moved on. He licked his way up her flat stomach, and reached her breasts once more.

Sakura heaved beneath him, eyes clouded and ready. She urged her hips towards his own, and Kakashi leaned down to kiss her on the lips. He took a moment to appreciate her face, wiping his thumb over her cheek.

Clearly, she wasn’t used to such doting attention because it momentarily disrupted the haze she was in. She looked away from him, and it made him wonder if she kept to half-assed hook ups….Or was Sasuke her only experience?

“Sensei…” he pressed his head against her batch of pink curls, hissing as her slick coated him. Sakura’s face twisted pleasurably, trying to urge him to go in further. 

“Mmm?” 

 

“I know…I know I shouldn’t say it right now.” God, he was so close. Kakashi could feel more pre-cum leak from his tip, but he had to tell her.

Sakura leaned up to kiss him, accepting his admission, “say it.” 

Their foreheads touched. Could he do it? He didn’t want to ruin things, not again. Not now. The only consistency in his life was her and his teammates, and he couldn’t imagine going back to a life where he entered an empty apartment. Loneliness would haunt him forever. 

“I love you.” 

 

Sakura kissed his forehead, and unlike last time where she nearly cracked her office in half — she smiled and wrapped her legs around him. It was her whisper in his ear that sent him over the edge, “never leave me, please.” 

It wasn’t reciprocated, but he wouldn’t want her to lie. Deep feelings such as his cultivated for years, so he could wait for her to fall in love with him. This was enough. In that moment he entered her, hard and swift until pink and silver meshed. They both cried out, hot snd heavy with a layer of sweat covering their bodies. Their lips met again, reverent and obsessive. Her legs hooked around his waist, and her nails left heavy half moons into his back from the intensity of her grip on him.

“You’re so…tight.”

It was better than he imagined.

His eyes almost rolled back, god she was so wet.

 

He picked up his pace at her command, setting a steady pace that allowed him to pull all the way out and sink back in. “Oh god, Kakashi!” She cried into his mouth, biting his lip in response to each thrust into her cunt. 

He held her close, using his free hand to lift her hips and bring one of her knees to hook over his shoulder. The new angle made his back shiver, and the pain of her nails digging into his back drove him further, abusing her mouth with his own. Their hips met, and with each slap he felt his cock swell dangerously. Fuck.

He was going to cum again.

“Sensei…!” He ground out, setting a brutal pace that pinned her to the floor. Her breasts bounced with each thrust, and the sounds that she was making while singing his name brought him closer and closer. 

Shit.

 

“I’m close!” Sakura moaned, “please, please…!” 

He almost fumbled, and for a moment he wished he was more experienced, more versatile because he was going to cum and she wouldn’t reach her-.

“Play with your clit,” he commanded, dark and guttural. Sakura reached between them and feverently touched herself, and it was enough to send her spiraling. Together, they climbed higher and he had several pumps left when he felt her walls quake around him and thighs quiver with the intensity of her orgasm. 

He assaulted her mouth again, “where do I cum?” he grunted out.

Sakura cried, barely aware as her orgasm made her body light and head spin with pleasure, “I-inside!” 

Oh god.

 

That was all it took, because he roared into her mouth, hips melded together and he kept her pinned there, his cock spurting into her for what felt like minutes. His eyes rolled back, and she kept herself clutched to him, cooing and kissing him while his body sank into her own. What felt like an eternity of unbridled pleasure, his balls felt empty when he finally came to. 

Barely able to keep himself up, Sakura kissed along his jawline, “it isn’t fair that the world can’t see your face.”

Kakashi could barely register what she said, and she peppered him with soft, loving kisses until he crumpled beside her. Gently, she took the mask off of his neck and climbed on top of him.

 

In the moonlight, her naked body sat atop him, and he didn’t care that his cum was leaking from her cunt and onto him. It was beautiful, and he hazily looked up at her, “I only want you to see me.”

Sakura smiled, tracing her fingers over his abs and the happy trail that led to the V of his hips, “from now on — I’m the only one that gets to see you,” she announced happily.

“Done,” he agreed, closing his eyes and heaving. 

It wasn’t even that long, and he was slightly embarrassed for his performance. 

 

“Your cheeks are red,” she laughed gently, not poking fun at him, but noticing his embarrassment reached his ears. 

Kakashi looked away, trying to will his blush to go away. “No, they’re not.”

“Don’t lie to me,” she scolded him, adjusting herself so she could sit on his cock.

 

Halfway aware of what was going on, still on the edges of reality from his last orgasm — he hissed when he felt his cock stir back to life and she swiftly sat on him. “I don’t want you moving…Ok?” 

Lazily, he nodded, barely able to hold onto her hips.

He waited, because in the dim light of the room — he realized the most beautiful woman on this planet sas sitting on his cock. Sakura lost her hands in her hair, gently and slowly riding him. He didn’t know it was possible for him to have anything left, but his cock hardened inside of her — springing back to life when she hilted them. 

“So…Big,” she whined, picking up speed on top of him. 

His thumbs squeezed her hips harder, sure to leave a bruise later. He wanted nothing more than to mark her forever, make sure it was known that her body was littered with gifts from him. Toned legs muscled their way so she could sit atop him and bounced on his cock. Her energy was unwavering, and Kakashi was left in awe — he couldn’t move, he became a puddle of sweat and skin melted with pleasure. 

“Senseiiii!” He whimpered, succumbing to her powress. Each time she reached the end of his member, she would squeeze and throw her head back. It was artistry to watch her enjoy herself on his cock, a prop used for her pleasure.

This was a woman, and he would never get forget this. He burned the image into his head. The long strands of her hair tickled his thighs, and Sakura set a pace that only a well trained kunoichi could keep up.  She rubbed her clit, propped up on one arm that was on his thigh.

“Sakura-sensei,” he breathed throatily, watching her like a predator starving in winter. 

Her muscles were lithe and worked hard beneath her skin, but the plumpness of her hips and ass curated such a beautiful body — he couldn’t get enough.

Weakly, he thrusted upwards, meeting her hips so he could hit that sweet spot deep within her.

Emerald eyes fluttered, and her cries reached louder decibels — a sweet song that he envisioned in his dreams. 

“I’m gonna come!” She squeaked, barely able to create a sentence. Edged by her sweet cunt, he gained his grip on reality and dragged her hips to meet his own. The sudden change of pace hit her  g spot, and between her pussy being hilted and clit being rubbed — Sakura broke on top of him.

“Kakashi, ungh!” She stopped mid thrust, her legs shivering and toes curling as she cried out her release. 

She must have exploded, because something happened that he only read in Icha Icha.

A liquid shot out of her at the precipice of her orgasm, and it left her with a silent cry as he brought her hips down one last time and her velveteen walls squeezed him until he came. Groaning and crying out together, the feral sounds they made caused their bodies to shake. He kept himself inside of her as he finished, drilling and grinding inside of her — uncaring of the consequences. 

Barely able to keep herself up, Sakura whimpered on top of him. The high of their orgasm left them weak and limbs akin to jelly, and they both crumbled to the ground. 

Some time later, when they both regained their breath, Kakashi dragged her close to him. If the window weren’t open, the room would surely smell of sex — but the fresh air ghosted across their skin and brought them out of their stupor.

Sakura tensed for a moment, and Kakashi felt her shift, “mmm, don’t move yet.” He was still inside of her, and he refused to move out of her beautiful vagina. 

“I-I’m sorry,” she mused off-handedly, and it took a moment for him to realize what she was talking about.

She squirted, and he almost forgot about it in the moment and he barely realized that both of them were sticky. He laughed against her shoulder, moving her hair to the side so he could expose her bare neck and nudged his head into the crook. He planted kisses and smiled against her skin, “I don’t care. That was…Hot.”He paused, mildly curious if this was a common occurrence, “does that happen a lot?”

This time it was her turn to blush, and she hid her face closer to the pillow, “only when I finish…myself.”

Kakashi smirked and continued to kiss her neck, “you’re amazing, you know that?”

“Stop it,” she goaded him, content and happy in his arms, “I’m embarrassed.”

“Don’t be,” he traced his finger to her breast and gently played with her nipple lazily. He was going to become a man obsessed.

Kakashi drew her closer if it were possible, and before they could fall asleep — he garnered enough energy to remove himself from her, upset that he wasn’t within her still. “Come on, let’s get washed up.”

And so he picked her up as if she weighed nothing and took her to the bathroom so he could clean her up.

 

Another round in the shower later, they retired to their mat — completely spent and barely holding onto consciousness. Sakura fell asleep first in his arms, back pressed to his chest and ass nestled against his crotch. 

It was bliss.

Unlike a month ago when he secretly toyed with her hair — wishing for something more but grateful to be around her, this time he had her in his arms and he moved downward so he could kiss between her shoulder blades. He fell asleep like this, the love of his life in his arms and the secret that he once held to himself, was now shared between them.

 

When they left the village, Sakura successfully saving the children within the Land of Waves — she left a hero and Kakashi was all too happily to be beside her in her success, admiring her like he did for the entirety of his life. 

They took their time returning to the village — and although it was supposed to be their secret, it clearly became obvious to everyone that they were exclusively dating. When they announced it, Obito and Rin congratulated them — Obito winked and slung his arm over his shoulder, “you finally made it happen, huh?”

 

Fortunately, everyone that knew them welcomed their relationship with open arms.

A month later, he moved into her home.

Half a year later, he proposed to her after setting up one of the most extravagant scavenger hunts that ended with her in happy tears, arms thrown around him with a loud and happy ‘yes, yes, yes!’

A year later, the sadness that crowded him since his father’s suicide seemed to fade — it would always be there, but he was happy and not alone.

It was no longer a secret, but now the world knew he loved Sakura Haruno — and she loved him too.

Notes:

I've been meaning to write this oneshot for years. It's partially inspired by an artwork by Youkaiyume that I saw on Tumblr years and years ago. Age swap KakaSaku is so fun to write, and I'm so happy I get to share this with the KakaSaku fandom!
. I apologize for any typos or wording that seems disjointed. I just really wanted to get this up.
I like to think that without the incident of Obito's death and killing Rin, Kakashi would be a lot different. I really enjoyed writing this slightly more awkward and unsure version of himself. Special bonus because Sakura as a sensei is just *chefs kiss.

Thank you again for taking the time to read!
