A/N: So, apparently boredom in department meeting had me writing things like this while pretending to take note. Un-betaed.
"Sweetest tongue has the sharpest teeth."
Gasping, Kakashi buries his long pale fingers into the thick midnight-like hair, pulling the other man closer into his embrace, deeper into his kiss, nearer to his soul—all violence and want in their clashing lips, tangled tongue and clanking teeth.
There is no gentleness in the kiss—nothing that bears any resemblance to the sweet reunion kiss in his sappy romance novel at all—but Kakashi is still drunk in the pleasure, leaning close to taste the vicious warm mouth.
Even after all these years, Obito still tastes heavenly sweet.
When he received the rather enthusiastic invitation for the reunion, Kakashi's first reaction was to block Gai's number and pretended that he was a caveman living under a rock inside a cave on an island at the middle of nowhere with no means of contact what so ever.
High school wasn't one of his best phases of life.
He has so many regrets from his high school years. So many mistakes done—some were so despicable and horrible that it was a wonder the world has not punished him for it yet.
Years. It took years of being an angry ball of angst hating the world before he had the senses knocked into his head, making him realised what he had done and turned his anger to utter regret.
Kakashi didn't wish to be among his old classmates and heard they talked about their fun high school years, completely oblivious to the darkness that he wrought to one of their brightest friends.
He spent these last ten years attempting to atone his sins after all.
All those time he spent staring at the class trip's picture that was framed by his bed, staring at bright onyx eyes in the picture and tried hard to forget the teary hurtful eyes his memories brought up.
He ditched his promising future as a neurologist to become a kindergarten teacher; all because he was haunted by a bright enthusiastic smile that was so similar to his students' smiles that it shattered his broken heart.
He always stopped in his path to help those who needed it—from little old ladies to angry yowling cat stuck in a tree—even when he was already late to his appointments, just because that was something that his first love would do.
The first love that he has ruthlessly broken.
Kakashi has no intention at all to go to his high school reunion.
It would break him all over again to see their incomplete roster and knew that he was the one who caused the absence of their class' bright ball of sunshine.
But of course, all hope of ignoring the invitation went outside the window when Rin literally broke his front door.
She was angry and petty enough to have him suffer through this reunion after all.
"That's so mean of you, Hatake," the brown-haired woman hissed, lips curled to a pleasant smile despite the way her eyes shone with malice and years-buried anger. "And one would have thought you would open the door for your first girlfriend."
She tossed the crowbar onto the couch, rounding over the coffee table to stand right in front of his hunched form.
"I'm not going, Rin," he mumbled, fiddling with his fingers. "I'm busy—"
"Moping?" she cut him off, voice cold and void of any pleasantries. "I'm not asking you, Hatake. I'm ordering you to come to our reunion."
"Rin," Kakashi sighed, lifting his head up to meet her gaze. "I—"
"You at least owed me that after all those years you lied to me, asshole."
Kakashi promptly lowered his gaze again to his lap, feet stretching under the table to toe with Pakkun's chubby belly. The little pug huffed and licked his toes soothingly, and Kakashi felt a little bit comforted that at least something in this world didn't hate him to his very core.
"I told you that I'm sorry," he murmured.
"And I haven't forgiven you," she deadpanned.
There was a beat of silence.
Then, there was a deep suffering sigh before the plush cushion next to him sink as Rin's warmth lined up along his own. She didn't touch him. Didn't offer a hug like she freely did during their high school years. Didn't reach out a hand to hold his shaking ones.
He didn't deserve the comfort of her touches anyway.
"He said that he will be there too, you know?"
That had Kakashi to snap his head up and stare at her in shock and hope.
"He is—?"
Alive?
He didn't dare to ask, fearing the answer that he would receive.
Red splatters and glazed dark eyes flashed into his mind, accompanied with the blaring sound of sirens and loud anguished voice of a horrified father.
"Asuma's father has a business connection with Uchiha-san," Rin hummed, looking outside to the horizon through the open sliding window. "We reached him, somehow. It took a collective effort, but he has agreed to come."
Kakashi took that information slowly, processing it with a twinge of relief washing his whole body.
He's alive.
Rin didn't even bat a lash when Kakashi buried his face to his palms and cried.
Obito's alive.
Nohara Rin was his first girlfriend.
But Uchiha Obito was his first love.
And Kakashi broke them both for good.
Kakashi didn't remember when he started to look at his classmate with eyes clouded with want and lust.
But he remembered seeing the sparks of love in Obito's dark eyes. He remembered seeing the adorable flush on the older boy's face every time the raven-haired talked with their class rep. He remembered seeing Obito's gaze lingered on Rin's back, only for the dark-haired boy to duck his head into his folded arms and smiled at the surface of his table. He remembered leaning over Obito's hunched shoulders and saw the delicate sketch of Rin's smile on the empty pages of what that was supposed to be their classic literature notebook. He remembered seeing the fond besotted smile that stretched over Obito's face whenever Rin laughed at his fumbling jokes.
Kakashi remembered seeing Obito falling in love.
And Kakashi decided to stop it.
He was delighted at the betrayed shock that splashed over Obito's face when he asked Rin out right in the middle of the class.
He was exhilarated with twisted pleasure when Obito's face contorted in pain and disappointment when Rin accepted his proposal.
Kakashi regretted that he remembered when exactly he started craving for Obito's pain.
"Hurt her and you'll pay."
It was cute.
Despite being two years younger, Kakashi towered over his crush by a few inches. He has always been tall for his age and when the school said that he should skip to a higher grade that would fit his genius mind, he blended right in with the classmates that were supposed to be his seniors of two grades.
And one of his seniors was so darn cute.
Obito was sprouting threats at him, yet Kakashi could only look at the older boy and wonder if those lips would taste as good as they looked like.
Would it taste sweet like all the chocolates Obito consumed on hourly basis? Would it feel as soft as they looked like—all wet and plush like that?
Obito's shock came in a choked gasp when Kakashi leant in and claimed those lips, silencing the threats with his hunger and greed for the older boy. He easily captured those resisting hands with his own, pinning the shorter teen against the wall, plastering his body to Obito's and slipping his thigh between the shaking legs.
Obito tasted heavenly.
And Kakashi couldn't get enough.
He squeezed the squirming wrists in his grip, tilted his head and pried Obito's lips open until he got to invade the resisting mouth, eyes closed in pure want when there was a tiny whimper that slipped the older boy's mouth. He kissed his crush thoroughly, wanting to claim everything that the older boy owned and by the time they separated, those lips were red and bruised from the kiss and Obito was breathing with so many difficulties that tears dripped from his eyes.
Kakashi felt oddly aroused at such pathetic sight.
He made his arousal known by rubbing up against the spread legs, pleased when he felt the half-forming bulge inside the dark fabric of their uniform pants.
Want. He wanted to own his crush so fucking bad.
And he had such a perfect hostage to get what his want.
"Obito-senpai~" he crooned, nosing the pulsing jugular of the bobbing throat. "I'm horny. I want to fuuuccck~"
I want to fuck you.
"Go fuck yourself, asshole."
Kakashi grinned.
"Why do that when I have a perfectly beautiful girlfriend?"
Kakashi knew that his bait was bitten when all colours drained from Obito's face.
"DON'T YOU DARE, YOU BASTARD—!"
The punch that hit his chest afterwards was weak and shaky it barely gave impact.
Obito was so darn cute, threatening and throwing punches at Kakashi over the girl that would never look his way.
"Maa, senpai," he cooed, planting his lips on the tantalising pale skin and suckled a love bite there. "Would you like to be her replacement instead?"
Kakashi knew that he has won when Obito jerked his chin and glared at him in the arrogant manner of all untamed lovers has before the older boy tugged him down for another kiss.
Kakashi happily indulged in that kiss.
See? The genius always got what he wanted.
Obito's defiance stubbornness persisted even after Kakashi has bent him over every surface possible and filled his tight sweet hole with sticky cum all the way up to the brim. The glare he directed at Kakashi remained fierce and defiant even when the younger boy forced him to beg for his own release. The hateful grit of his teeth was present and radiated with hatred every time Kakashi forced him over the edge. The way he picked up himself with a strange defiant resolution to ignore Kakashi was firm and unwavering, even after the younger boy pestered him for a kiss or two.
Somehow Kakashi found no pleasure in their arrangement.
He wanted to see obedience and pain. Not this stubborn defiance.
Thus, he stepped up the game.
It wasn't long before Obito started to crack.
"P-please!"
Kakashi grinned and leant down to bite the bruised throat, honestly enjoying the thought that Obito would be receiving lots of questioning look for wearing a turtleneck inside his uniform in the middle of summer. He slid out of the abused hole before ramming back in, earning him a startled choke from the older boy.
"Please, it hurts..."
Kakashi hushed him with another thrust, loving the way Obito's grip on the sheets grew slack while heavy breath escaped his battered bruised body with way too many difficulties to be normal.
"I'm sorry," Obito's voice was soft and ragged. "Kakashi, please..."
Kakashi kissed the tears away.
"Maa, that wasn't so hard right?" he hummed, kissing the gaping lips with furious passion. "If you behave from the beginning, I won't have to resort to hurting you to make my point," he added, fingers skimming lightly over the bruised ribs.
"I'm sorry," Obito wept, hurt and broken.
Kakashi kissed him again.
He did it. His beloved crush has completely submitted to his whims, broken after the humiliation and abuse Kakashi has put him through.
It took half of the school term to train his lover to be obedient to him, but it was worth it.
Not that Kakashi didn't enjoy the training period. There was something unexplainably arousing to watch Obito's back and knew that the older boy was struggling to not loudly react every time Kakashi toyed with the settings of the remote. It was necessary preparation to loosen that hole up because their lunch break was short and Kakashi really wanted to eat his lunch, so either Obito agreed to that or Kakashi would fuck him raw and dry in the school's toilet stall.
It was even more satisfying when Obito's training ended up better than expected, making the older boy so pliant and obedient like a pitiful dog, submitting to Kakashi's whims with unwilling tears in his eyes.
It was so arousing and fun. Kakashi enjoyed the tears that glazed Obito's dark eyes. He was in love with the pained whimper that slipped past the older boy's mouth, enjoying the way Obito's sensitive body tore open under his harsh thrust and blood trickled down along with his semen down the pale thighs. He enjoyed the horrified look on Obito's face when he immortalised the beauty into his phone's memories, keeping a specific folder in there to keep him company whenever Obito's father visit and he could not enjoy his sweet little lover.
Not that it stopped Kakashi from fucking Obito raw right on the man's bed as Obito struggled to act normal while answering his father's call.
Good times.
Kakashi was over the moon. Sure, he still has to spend some time to pretend to be a good boyfriend for Rin, but Rin was busy with her college's entrance exam anyway, so there weren't many dates for Kakashi to pretend that he would enjoy. All in all, Kakashi was happy to have Obito to himself.
His deluded mind didn't pick up on the way Obito's bright eyes have dulled.
He didn't notice the way his beloved lover curled up on himself and cried after Kakashi was done using him.
He didn't realise that Obito's body has grown so broken under the abuse.
He didn't realise that Obito's mind was fractured with trauma and hurt.
He didn't realise that he has approached his love in a horribly wrong way that it ended up destroying everything that he has loved.
He didn't realise everything until it was too late.
He didn't realise it until he met Obito's glazed empty eyes as blood bloomed on the black asphalt like some morbid mockery of the red roses in his hands.
In the midst of blaring sirens and hushed horrified voices, Kakashi watched in numb horror as the light faded from his first love's eyes.
