osamu and atsumu grew up having to share everything they received; food, sometimes clothes, and surprisingly, girls. when they started going to high school, despite the fact that whoever gets a girl first they would end up sharing.

now, it was spring nationals and atsumu decided to watch the other team's gameplay. in the corner was sakusa kiyoomi, looking mortified as he was trying not to get too close with the crowd.

atsumu noticed sakusa whom he met at the youth training camp before the nationals.

atsumu was obviously interested in itachiyama's ace. he pondered about how sakusa would look when he fucks him, and how would kiyoomi react if he spread his legs for him.

yes, atsumu wanted kiyoomi to fuck him.

it was kind of unbelievable, but atsumu wanted him. so bad.

atsumu decided to talk to him but osamu called out for him.

"ya pig, where d'ya think yer going?" osamu asked, head locking his head.

atsumu elbowed him but osamu didn't budge. "gonna talk to someone I know." he grumbled, his attention fixated on kiyoomi and osamu noticed.

osamu grinned, "so are ya topping or bottoming, tsumu?" he jokingly whispered on atsumu's ear.

"I'll bottom..." atsumu unaware that he said it loudly. osamu's grin grew wider and seconds later, atsumu realising what he said so he pushed osamu away from him "what are ya sayin'?"

osamu stared at his twin with mischief on his eyes, "ya know the drill, tsumu."

atsumu was burning red, the thought of him and osamu sharing kiyoomi was beyond his fantasy. but it also excites him, he would love to see kiyoomi squirm under his twin but kiyoomi boning him...

it was more stimulating.

atsumu looked at his twin, and as if reading osamu's mind, he decided to talk to kiyoomi.

"hey omi!" atsumu greeted him, making kiyoomi flinch.

kiyoomi stared at him and atsumu shuddered at his gaze.

'ah, fuck me.' atsumu thought.

little did atsumu know that komori was just near kiyoomi, looking at the both of them with a huge grin on his face.

komori had a playful idea, he sneaked behind atsumu and saw osamu urging him more. he then pushed atsumu to kiyoomi, the blonde crashing into kiyoomi's chest.

atsumu had his face buried in kiyoomi's chest, he mentally cursed but the bright flush on his cheeks says otherwise.

'shit, calm the f down atsumu' he scolded himself.

the reason? he got turned on by kiyoomi's hard chest, those large hands supporting his waist and his scent.

meanwhile, kiyoomi was stunned. the feeling of the blonde's slim waist was not he was expecting. he liked the feeling of his hands holding him, he thought about how he would feel if he put his arms around him.

kiyoomi groaned at the unexpected reaction of his body.

he was in utter disbelief. and it was a mistake the moment he looked down on atsumu. atsumu was blushing mess and he felt the arousal on his legs.

he pushed atsumu gently before running to the bathroom, leaving the blonde frozen on his feet. moments later, atsumu followed him.

osamu knew what was happening, so left the scene.

kiyoomi's was grumbling, muttering curses as soon as he got inside the bathroom. he was embarrassed of himself for getting turned on from just holding atsumu miya's waist. those slim waist... he would love to hold him again.

oh god, it frustrates him even more. he glared at the noticeable arousal on his jersey shorts as if it would really calm down if he did that.

"fuck! this is insane. getting turned on from slight touching? you're crazy, kiyoomi." he talked to himself.

"then fuck me, omi."

kiyoomi's heart nearly jumped out of his chest. he snapped his head to the owner of that voice, and saw atsumu sheepishly smirking at him. that look on atsumu's face was telling him to do it.

'do I really want to fuck him? in this disgusting and clean bathroom?' he thought.

he grimaced at the thought, but fucking atsumu didn't cross his mind. he may or may not do it but it was eating his logical thinking.

kiyoomi was too immersed that he didn't noticed atsumu walking towards him. he slightly flinched when he felt a hand pressing on his chest.

"ya know omi, I could make ya kiss me with just me staring at ya." atsumu whispered on his ear.

"w-what? what are you...miya?" he was blushing and stumbling over his words when atsumu just stood there, his arms around kiyoomi's neck.

kiyoomi didn't know what to do.

he was awestruck. seeing atsumu up close, he can see all those distinct features that he once noticed in the youth training camp.

but what pulled his attention was atsumu's lips. it looked like it was inviting him for some reason. maybe what atsumu said earlier was true.

kiyoomi wanted to feel those lips, he wanted to taste him.

atsumu noticed kiyoomi's hesitant expression. he was already partying on his mind. kiyoomi wants him. atsumu had to stop himself from jumping on him. he knew kiyoomi got hard earlier that's why kiyoomi pushed him.

kiyoomi was contemplating but the more he thought about it, it was agonizing for him. 'fuck it.' he thought.

atsumu was about to open his mouth when kiyoomi grabbed a fistful of his hair as he roughly kissed him.

'ah, this it it.' atsumu cheered in his head.

atsumu responded to his kisses, not letting him take control of it. he felt kiyoomi biting his lips as if he wanted more.

atsumu softly giggled, "told ya I could make ya kiss me, omi." he taunted.

kiyoomi was annoyed that atsumu stopped, so he did what needs to be done.

he suddenly grabbed his waist, carried him and put him on top of the sink. atsumu was shocked, he didn't know that kiyoomi would react like this.

it was thrilling.

atsumu felt so hot, kiyoomi had him wrapped around his arms, and atsumu had nowhere to go.

the moment atsumu looked at kiyoomi, he was again getting devoured by him. kiyoomi started kissing him aggressively, his hands gripping and caressing his waist at the same time.

an unbelievably loud moan escaped from atsumu's lips. he didn't know he would be that loud.

kiyoomi left his lips, making atsumu whine like a needy cat. but then he shuddered when he felt kiyoomi's lips on his exposed skin, kiyoomi had rolled up atsumu's jersey up to his neck.

"I didn't know ya would be like this, omi." atsumu breathed. "I could've stripped for ya."

it was then that kiyoomi heard the alarm signaling him to stop, but the constant whispering of his inner demon was louder.

atsumu froze when kiyoomi looked at him with those dark brooding eyes.

kiyoomi grabbed him by the throat, almost choking atsumu. "do it. strip, miya."

thereupon, atsumu was completely naked in front of the mirror, ass up in the air while kiyoomi was balls deep inside him. pain and pleasure took over his body, and atsumu knew that he won't be the same again after this.

"I'm gonna wreck you, miya." kiyoomi growled behind him.

atsumu let out the sluttiest, loudest scream kiyoomi ever heard. atsumu was now pushed against the sink as kiyoomi was literally rearranging his guts.

atsumu knew that he'll be ruined, but he didn't care. this is the best sex he ever had and he never wanted it to end.

"you wanted this right, miya? you were aiming for this the moment you went to talk to me." kiyoomi snarled.

atsumu was struggling to form words, the feeling right now was too much.

but kiyoomi was not patient enough, he slapped atsumu's ass hard that it echoed across the room.

atsumu almost fainted at the stinging pain in his ass, he had tears in his eyes when he felt kiyoomi's hand on his neck, choking him and the other gripping tightly on his waist while he aggresively pounded into him.

"god, you look so pretty miya." kiyoomi growled in his ear.

atsumu can barely open his eyes, but when he looked at the mirror, it felt like he was almost near.

his skin looked so flushed, he was sweaty and he can clearly saw kiyoomi's cock penetrating him. it was a sight he wanted to happen again.

"you're loving this, aren't you? +

you love it when I fuck you like this, don't you?" kiyoomi bit his neck, leaving a mark on atsumu's skin.

atsumu moaned, nodding helplessly at him. kiyoomi almost lost himself, seeing atsumu thrashing on his hold was enough to make him lose his mind and fill him up to the brim.

"look at me." kiyoomi spat and atsumu quickly obeyed, giving him a clear view of the pleasure etched all over his face. both were staring at each other through the mirror.

"if you tell me that you'll bend for me the next time I tell you, I'll let you cum." kiyoomi said to him.

"how about you guys start fixing yourselves?" a familiar voice interrupted the both of them.

atsumu almost lost his shit, he had to curl up against kiyoomi to hide himself and kiyoomi had no choice but to hug atsumu with his butt exposed to the person who suddenly showed up.

"WHAT THE FUCK SAMU?! WHY ARE YA HERE?!" atsumu shouted.

'was he already here since earlier? why didn't I notice him?' atsumu thought despite the embarrassment going through his whole being.

kiyoomi cleared his throat, grabbing osamu's attention and the latter looked at him.

"this is embarrassing but can you give your twin a time to fix himself?" kiyoomi uttered.

osamu had his arms crossed, amused at kiyoomi's calmness. he glanced at his twin, still curled up beside kiyoomi.

"ya jerk, put yer clothes on. don't act like a virgin." osamu spat.

"I AM A VIRGIN! OMI HAD MY ASS FIRST!" atsumu yelled, completely unaware that kiyoomi was just beside him.

"look at ya, being so proud having yer ass fucked by sakusa-san." osamu had a smug look on his face.

kiyoomi had covered his face in humiliation, and atsumu realizing +

it a little later had both of them blushing, and had osamu roaring in laughter.

osamu wiped the tears formed in his eyes, "man, ya both looked so funny." he cackled.

atsumu groaned at him and kiyoomi had to turn his back to the twins as he tried to calm himself.

"but ya know, I would like to know how would sakusa-san look when I fuck him raw." osamu suddenly blurted out.

both kiyoomi and atsumu turned their heads at him, bewildered by osamu's sudden declaration.

"WHAT?!" both screamed in unison.

osamu looked at them. "what?"

END.

maybe?
