****** Losing It ******
by esbee
Summary
     Written for the kinkmeme. Prompt: Back when Oikawa was under a
     tremendous amount of pressure and felt envious of Kageyama’s skills
     in Kageyama’s 1st year, Kageyama asked Oikawa for tips all the time.
     Instead of Iwaizumi rushing in to calm things down when Oikawa almost
     struck Kageyama (I forget what chapter this is), Iwaizumi is absent
     and fails to prevent Oikawa from losing it completely and taking it
     out on Kageyama.
Notes
     I've had multiple people comment to me about this fic so I'm going to
     WARN YOU for the last time: this is EXTREMELY non-consensual. Please
     do not read if it will upset you.
That first strike just felt so good.
Like taking the lid off a pot of boiling water, Oikawa could feel the steam
bursting from his skin as the vibrations of the impact shook through him.
The younger boy stumbled backwards, eyes wide and piercing. One hand grasped
lightly at his swollen cheek as he took a short, sharp breath. The eyes shifted
suddenly, locking onto Oikawa’s with hot intensity. The boy didn’t even have to
smile to show his entertainment, it was apparent in his body and voice: “Are
you jealous?”
The worst part of it all was that it was true. Oikawa was jealous. He was
crazed with jealousy and regret- all the years he’d worked so hard, and with
his pinnacle match coming up so soon here comes someone just blooming with
natural talent. Natural talent. It was a thought Oikawa hated. How could
someone be so talented without working nearly as hard, or as long? How was it
fair?
The older boy grimaced and lunged, slamming his knee into the boy’s stomach
with the best of his weight, knocking the smaller figure onto the gym floor
with a thud. He was writhing from the release of energy, and relishing in the
relief of being able to assert his own power. The power he’d worked so damn
hard to cultivate all this time.
“Why don’t you just shut up, Kageyama?”
Eyes still hot, the boy sat up from the floor and made a move to attack back,
but Oikawa was bigger and already upon him, slamming his shoulders downward
with force. They struggled, the older asserting his advantage in size while the
younger flailed and kicked. Kageyama’s face twisted into a scowl, which only
provoked Oikawa’s anger even further. He slammed his fist into the face below
him, striking the same cheek. The skin rippled and puckered; Kageyama coughed
blood.
He still struggled, despite the blow, lifting a leg and arrowing his foot into
Oikawa’s crotch. He kicked with adrenalin pumping through him and the force was
enough to cause the older boy’s entire body to freeze and tense.
The pain was like a million hands inside of him, twisting and squeezing his
organs. Oikawa gagged, clenching the muscles around his mouth. He managed to
stay on top of Kageyama, though the boy was desperately trying to take
advantage of his last blow and scoot out from under him.
“L-little..bastard..!”
The pain was still there but Oikawa fought through it, grabbing onto Kageyama’s
shoulders even tighter and holding them down as he lifted a knee and pressed it
deep into the boy’s crotch. Kageyama’s dark eyes tensed and widened, pupils
shrinking. His arms and legs thrashed against the weight on top of him, the
sharp pain spreading in his stomach as his balls where forcefully squeezed back
into his body.
“It..hurts! It hurts!” the boy gasped, though his voice still managed to be
dripping with hatred. Oikawa’s anger sparked again, and he grabbed at the boy’s
collar. He lifted and then slammed back down over and over, Kageyama’s head and
shoulders bouncing with each thrust, slamming into the hard floor with repeated
thuds. Oikawa’s knuckles where white and his legs trembling. His knee angled
and pushed even harder until Kageyama was could no longer fight against the
pain. The best the boy could do was try and lift his neck so his head didn’t
crack against the floor with his shoulders and bring his knees up to clench the
muscles of his thighs against the pain.
Oikawa suddenly stopped his hands, his eyes softening. It was quite the sight.
The usually wide-eyed determined little fuck was bleary beneath him. His legs
spread and tense, his fingers in tight fists against the floor, his face
twisted in pain and tears forming in the corner of his eyes. Like this he
hardly looked like a threat or a prodigy- like this he looked like a cute
helpless thing. It felt good to see him this way.
It felt too good- it was uncontrollable. Oikawa wanted more of it. He wanted to
see it through even further, feel a better release. His skin sparked  with
goosebumps and moved instinctively- almost too quickly for his brain to
comprehend. He scooted back, finally releasing the boy’s crotch. Kageyama
sighed briefly but then made a grimacing sound as Oikawa dove fingers under the
elastic of his shorts and pulled them down past his knees.
Shocked- perhaps terrified- the dark haired boy started to fight back again but
his blows meant nothing to Oikawa. The brunette dipped his head and torso in
between Kageyama’s legs, so that his knees were forced open, but his tennis
shoes enabled his shorts from coming completely off so his ankles were together
behind the older boy’s back. In this position it was hard for him to use
anything else but his arms.
He pushed against Oikawa’s chest but the boy lunged forward, forcing elbows to
bend. Hands clutched his thighs and forced them apart even further. Kageyama
wiggled and shook, eyes wide and searching as the panic dove down his throat
and into his stomach.
“Wai-wait! Stop!”
Oikawa didn’t stop. With trembling hands full of some crazed, excited power his
kept on. He pulled down his own shorts just enough to pull out his dick which
was twitching into life.
Kageyama gasped and wiggled even more, burrowing his heels into Oikawa’s back
with a painful force. Oikawa stroked his cock quickly, leaning forward and
biting down on the boy’s neck until he drew blood.
The noises that left the dark haired boy were like some sort of spell to
Oikawa- they sounded like a chant and filled him with even more desire. He
wanted to conquer- he wanted this so badly he could hardly contain his own
shaking body. His muscles trembled with a sick delight as he lost patience and
positioned his now hardened member against the pink folds of Kageyama’s ass.
A small, broken voice sounded in his ear as he continued to bite down on the
tender neck. “Wait…just don’t. P-please don’t…”
Oikawa forced himself in, dry. The inner walls of Kageyama’s entrance squeezed
against it, contracting and pulling against him as he pushed. It took several
frustrated thrusts to get the right angle, but eventually it took the length of
his dick inside.
To Kageyama, it felt terrible. Like some sort of raw scratching, spreading and
splitting his insides apart. He wailed and twisted with clenching muscles,
desperate for release from the pain. But even worse than that, he felt
humiliated. Washed over with regret and sorrow- the emotion flooded his body.
He felt disgusting- violated. Each thrust felt like it was cursing his body. It
was painful and devastating. He choked and let out a whimper, clenching fists
into Oikawa’s shirt as he pressed against his chest.
To Oikawa, it was like some sort of miracle. His entire body and soul felt such
a rush of relief- it was like nothing he’d ever experienced. All at once, all
his anger and all his frustration was taking root and blossoming beneath him.
It was tight and pleasureful- his cock felt like it was being sucked inside as
he pulled back, and then welcomed back in as he thrusted forward. He let
himself loose control, basking in the feeling and going harder. He moved his
hips with as much speed as he could, scraping against dry walls and feeling
pleasure pool in the bottom of his stomach. This was it. This was what he
needed all along.  
Kageyama thought it was never going to end. Eventually his ass adjusted, but it
still hurt. It hurt him right into his soul- past any point that his body could
feel any pleasure itself. His cock laid flaccid against his stomach, unaffected
by the persistent thrusts inside of him.
Oikawa gasped and came- he hadn’t even realized he was so close until he was
spilling out into Kageyama, who clenched down tighter against it, wailing at
the feeling of hot liquid filling him. Oikawa looked down, staring at the boy
beneath him, who had tears streaming down his face and his eyes clenched shut.
His expression was distressed and scared, his mouth hanging open and
trembling. Is it already over? So soon?
The older boy sighed and smiled, lifting up and keeping his hips arrowed
towards the other boy. No- he didn’t want to stop. He wrapped hands around
Kageyama’s thighs to keep him from moving and he waited. He waited until he was
fully erect once more, growing little by little inside of the boy still.
Kageyama broke out into a sob. He couldn’t believe it still wasn’t over- how
long was it going to last? When Oikawa started to move this time, he came in at
a different angle, and it felt smoother, lubricated with his own cum.
The boy gagged at the thought, his voice cracking with each sob, his shoulders
shaking. He lifted hands to cover his face as he was pounded into for a second
time.
When would it end? When would it end?
Oikawa never wanted it too. He hadn’t felt so calm in the longest time. He felt
like himself again. He took his time this go around, making long forceful
thrusts with a slow burning power behind them. He closed his eyes and listened
to the crying noises that seemed so distant. His brown hair stuck to the sweat
around his smiling face. It wasn’t until he heard Kageyama’s voice take more
form that he opened his eyes and looked down.
“D-do…you really…ah!…hate me this m-much…?”
Kageyama was staring up at him, eyes dripping and pleading. Oikawa continued to
thrust, waiting for quite a while before he decided to respond, just aimlessly
pushing and pulling within him at an increasing rhythm.
By the time he finally leaned forward and brought their faces together,
Kageyama had half forgotten that he’d even said anything, so worn from the
abuse and rape that he thought he was going to pass out right there on the
floor.
Oikawa looked down at him, his expression soft. He was smiling and his eyes
were kind and pleased. He looked as if he was about to profess an everlasting
love- Kageyama felt confused and disgusted all at once. Oikawa chuckled and
nodded, whispering.
“Yeah, I really hate you this much.”
He came a second time inside of Kageyama.
