The library became his sanctuary when he wanted to avoid his big brother. Everything is suffocating in this school. His brother was suffocating.
Yoichi always resented how much power his big brother had over him. Sure, he loved him with all his heart, he was his only family member that cared about him and took care of him since he was born, having neglectful parents who were always either drunk or fighting each other, without his brother he certainly wouldn’t be alive today.
But that didn’t mean he was perfect, far from it. Yoichi knew damn well that his brother is a manipulator who craves the control of every single aspect of his life, it made his school life hell, he only had one friend, if it weren’t for Nishi Bakugou then no one ever bothered to talk to him.
Everyone avoided him like plague, except when he needed help with something, even the teachers were fearful of looking at him in the eyes for fuck sakes!
He’s aware that it was because of his brother who was unofficially the school’s « king », being a straight A student, and the school’s council president, it wasn’t an understatement to say that the school principal had less power than his brother. How did he gain so much power in so little time? Yoichi will never know.
So yes, Yoichi understood that his beloved big brother was a shady person, but unfortunately for him he still loved him, but even if he loves him, he resented how much his brother treated him like an object to hide away and protect, like a possessive dragon. It’s true that Yoichi’s health has always been fragile, but his brother was way too overprotective.
Yoichi was pulled out of his glummy thoughts by a large hand softly caressing his lower-back, a deep voice behind his ear and hot breath that made him shiver.
« Are you avoiding me my sweet outoto? » his brother said with a purring voice.
With a resigned sigh Yoichi tried to put some space between them but the large hand possessively embraced him even tighter against his brother’s broad chest, really, he didn’t win the genetic lottery by being smaller than him!
Squirming against his hold Yoichi growled « Can’t I have some alone time to myself?! Beside you were busy with council meetings why are you here? » Yoichi was pouting resigned to be cuddled against his will.
« Yes, I was busy, as you know Prom is coming soon, and everyone is looking forward to this event, so I had to make sure everything is perfect ».
Oh yes Prom is soon, that’s probably why everyone was acting all lovey dovey, not that Yoichi cared since he wasn’t planning on going in the first place, he would rather stay in his room and read comics with Nishi, it would be a nice evening without his brother to hover around him like a hawk.
Still, he wondered who his brother will ask as his date, whoever this poor soul will be, Yoichi already feels sorry for them.
« I forgot about the prom, not that I cared about it since I don’t want to go” he shrugged
“You should pay more attention, it’s a once in a lifetime event and your dear big brother is the one overseeing everything. I’m sure you’ll love it when you’ll see how beautiful the decorations are » with a knowing smile he started to comb through Yoichi’s silky hair.
“It doesn’t matter I’m not going” he said, tensing when he felt the large hand caressing his hair and his neck.
“What if I ask you to come with me as my date? Are you going to deny me Yoichi?” He continued to caress his neck, slowly pressing on tensing muscles, drawing a sound of pleasure out of Yoichi.
Yoichi bit his lips to stop making any sounds, silently stunned at his brother’s question. He would like to be shocked that his own brother wants him as his date, but unfortunately, he suspected this exact scenario to happen one day.
He wasn’t blind and he knew half of the school’s population is pining after his brother, but this charming asshole always rejected every confession without being hated or seen as a jerk. Any other boy his age would jump at the chance to date so many cute girls or boys and get their dicks wet, but not his brother. He was the one who built the image of an unattainable god, who could only be worshipped from afar and not touched. It annoyed Yoichi to no end.
Yoichi isn’t sure about what is going through his brother’s head, why would he want his little brother as his date? Is his brother complex that bad? He shudders at the idea and thinks about how touchy his brother had always been with him, how he would wake him up in the middle of the night with a tight embrace, his broad body always seeking contact with his small one. How he would smell his hair or caress his skin. Yoichi started to feel a slight wave of nausea.
He is now uncomfortably very aware of their position and tried to get out of his embrace, but his brother is way stronger, so he gave up and looked at his unnerving piercing red eyes so focused on him.
« I shouldn’t be your date I’m your little brother, beside I’m sure you could have anyone you want. In case you didn’t know half of the school would kill to be your date » he said with a shaky voice
« I don’t want anyone but you and only you. Please outoto, it would make me happy and only you have my trust. I know you won’t take advantage of me like those vultures” His brother said burying his face on his neck, inhaling his scent.
Yoichi hated how much his pleading tone affected him. After all his big brother always protected and looked after him, and if going to prom as his date is what makes him happy, it shouldn’t be that big of a deal right? It’s still weird, but not that weird, it’s not unheard of to go with a family member in a formal event. It should be okay.
« Ugh fine but I don’t want to stay until the end”
“Wonderful I’ll have someone drop your outfit off, you’ll look beautiful in it I can already imagine it”
Yoichi felt so uncomfortable in his brother’s grip, feeling his leering gaze
“How do you already have an outfit planned? You knew I’d say yes don’t you?”
“You know I’m always ten steps ahead, of course I had everything ready”
“Ugh you’re really pissing me off!”
“But you love me” with a smirk he finally met Yoichi go “I have to go, now, but I really look forward to our date, see you soon my sweet outoto” before Yoichi could react, he kissed his cheek and left with a mocking laugh.
“Why can’t I have a normal sibling who’s not a creepy asshole?” Yoichi felt the urge to scream but sighed as he sat down to study.
‘Maybe this prom is a bad idea?’ With that thought in mind Yoichi decided to ignore the matter until the dreaded day.
Yoichi shouldn’t have ignored this matter, cursing himself he stared at his reflection in the mirror and wondered how far he was willing to go through just to please his brother.
A beautiful white dress, with just the right amount of cut to show off his dainty neck and hide his « flat » chest, the dress also had a cut that put his smooth milky pale thigh on display.
With some light make up that made his green eyes stand out and bigger, and his dusty pink cheek coated with baby pink blush, his hair was also tied in a complicated high bun. Yoichi really looked like a woman.
‘But I’m a boy! Why am I wearing this?!’ He was pulled out of his angry thoughts by a low voice.
« Beautiful…I knew you’d look like you’re out of this world. You look ethereal.” His brother’s red eyes looked almost dark, with dilated pupils, or was it a trick of the lights?
«Why did you give me a dress! I can’t wear that !!!” he growled
« This dress was tailored for you, it suits you. If you are worried of someone making fun of you, don’t be, no one will dare to tell you anything except that you are beautiful. »
«That’s beside the point! I don’t want to wear a dress! I want a suit! »
« Yoichi don’t be difficult, you’re already wearing it, now come or we’ll be late.”
Yoichi didn’t have time to react before he was being whisked away by his brother. Fuming inside, he was mad at himself for being so easily manipulated by his him, he should have known he would be humiliated, treated like a doll.
His brother may say that he accepts Yoichi as his brother, but he knew that deep down he would always be a girl in his eyes, and that hurt more than Yoichi thought it would.
Before he knew it, they arrived in front of the school. There was a lot of fairy lights and a huge red carpet filled with many students all well dressed, talking among themselves.
When he made a move to get up his brother beat him to it and opened the limo’s door for him ‘like a woman’ Yoichi thought bitterly.
Instantly all eyes were on them, what a sight they must be. Him with his petite stature and his brother with his hulking figure, his big arm wrapped around his dainty one, both of their white hair always made them stand out but now it was clear that they looked ethereal. Yoichi was so flustered at the idea of people thinking he was woman.
« Don’t be nervous dear one, you can rely on me, this night is supposed to be enjoyable for us » his brother whispered in his ear while rubbing soothing circle on Yoichi’s hand.
« I wouldn’t have to be nervous in the first place if I wasn’t dressed like a woman. I hope everyone remembers we’re related; god forbid they also think I’m your girlfriend” he shuddered at the suggestion.
“Let them think what they want, beside we won’t stay with everyone for long, I prepared something special just for you” he said with a purring voice.
“Well, I’m even more worried now”
His brother only smirked at him, his patronizing smile always made Yoichi angry, it was like he was amused by a joke only privy to him.
With a huff he resigned himself to be escorted by his prick of a brother, his huge hand squeezing his lower back, making him involuntary shudder.
They passed past the crowd of students and soon they arrived in a lovely gazebo decorated with even more fairy lights. There was a table filled with Yoichi’s favorite snacks, and in another corner, there was a mattress covered by many soft looking pillows. It oddly looked like a nest, and it made him want to lay down in it and take a nap. Yoichi wished he could hate his brother’s work, but he had to reluctantly admit that it was everything he loved.
“So pretty” he unconsciously murmured out loud
“I’m glad you like it Yoichi, believe it or not but I really want to make you happy, just like how you make me happy to call you mine” his brother said, red eyes gazing in his own green ones.
“Thank you, but you know you didn’t have to do this, if you wanted to spend time with me, we could have stayed home”
“It wouldn’t be the same, but enough chit chat. Now, may I have this dance my lady?”
“I’m a boy!!” He growled
With his mocking face, his brother suddenly caught him by the waist, both of his large hand tightly wrapped around his waist. He was forced to rest his own hands on his brother’s shoulders, much to his dismay.
They both started to slowly dance around the gazebo, the song setting a romantic vibe that unnerved Yoichi even more. He tried to avoid his brother’s stare by looking around. But he was soon forced to look at him when he started talking lowly in his ear. Yoichi wished he could be anywhere but here; siblings shouldn’t slow dance to a romantic song together!
« You know Yoichi, maybe I don’t say it enough, but I love you, I really do. I would burn the world for you if you just asked » with his intense look, Yoichi could only shudder in response « I’ll do anything to protect you, you are my one and only family. Mine.». With that his brother hugged him tightly and breathed in Yoichi’s scent.
Yoichi was so flabbergasted by this confession, he knew his brother cared about him but for him to spew such disturbing things, he was very concerned, and creeped out.
« I-I love you too Nii-san, but please there’s no need for you to protect me or « burn » the world down, I’ll never forget how much you took care of me when we were children but I’m practically an adult now » Yoichi tried to gently smile at him, because even if he was a total creep, he does love his brother.
Beside he was going to turn 16 soon and his brother will graduate next month at 18, so he wouldn’t have to suffer from his protective grip when he’ll leave for college.
His brother didn’t respond, he pulled him in a tight hug and with his trademark annoying smirk, he suddenly murmured « do you want a drink? Tonight, I’ll let you try alcohol it can be our little secret » he winked
« What?! We’re underage! And how did you even manage to smuggle alcohol here?”
“That’s for me to know, now here try this, it’s a sweet wine I’m sure you’ll love it” He handed him a fancy crystal-clear glass filled with red wine, the color was so vibrant that it looked like blood. He was instantly suspicious, he wouldn’t put it past his brother to prank him, but the drink did smell sweet, sweet enough to make his mouth water. He always had a sweet tooth.
Deciding to take a leap of faith, he took a sip and closed his eyes at the divine taste, he let out a small moan involuntarily, and downed the entire drink in one go. It made him thirsty for more.
When his eyes opened, he finally noticed his brother’s hyper focused ruby eyes, they were nearly dilated, he flinched and tried to avoid his gaze by looking at the cute little pastries on the table, only for his brother to forcefully turn His face, forcing Yoichi to stare at the intimidating oddly dark red eyes.
« So how did it taste little brother? For you to moan without a shame it must have been pleasurable” His brother’s voice was also alarmingly rough.
“I-it was very delicious, thank you. May I have another please” he wanted more but he wasn’t sure if his brother would let him have enough to get drunk, and with how anxious he was, he sure as hell hoped that the alcohol would help to relax him.
“Of course, baby brother, here let’s share the next one » he took another cup and slowly drank the dark liquid all the while staring at Yoichi directly in the eyes, with an intense expression. Yoichi was starting to feel hot in his dress, and he felt sweatier with his brother’s heated gaze on him.
« You were right, it does taste divine. Here, your turn now » his brother licked a drop of the wine on the upper corner of his lips with his tongue, his red eyes never leaving his own green one, and it made Yoichi feel even hotter, he was starting to think that he had a fever.
Yoichi nearly ripped the drink out of his brother’s hand and downed the drink in a go. It made his head spin, but he instantly felt less anxious.
With a lighter mood, he giggled and swayed at the pop song that was playing, finally changing the romantic atmosphere with something that made him want to dance. He started to move his hips to the song’s rhythm, his long dress enhancing his every move. he let his silky white locks fall, the bun completely destroyed, and he spined, giggling harder as the song ended.
A deep chuckle made him stop and he felt his brother’s broad body hugging him from behind, his hands squeezing his hips. A new song started to play, this one was more…explicit.
“Why did you stop to dance sweetheart? You move your body in such a beautiful way, this dress make you even more irresistible, why don’t you give me a little show?” His brother’s voice was hoarse, his hand felt burning hot on his own sweaty skin, even with the dress shielding him from skin to skin contact with him.
Okay, not only was Yoichi drunk, but he just realized that his brother was as drunk as him. Damn this wine must have been strong as hell, even with how sweet it was, for them to be this drunk, it wasn’t normal. But Yoichi was far too gone act rationally.
His brother was breathing hard, red faced and his eyes looked dark, nearly black. Yoichi shivered, unsure if he was excited or creeped out.
Seeing as he was frozen, his brother took it upon himself to move Yoichi’s hips against his own body. Yoichi was grinding against his own brother, his only real family, he wanted to panic but the drunk haze made him crave more contact with the hot body locked against his frail one.
As the song reached its climax, Yoichi started to really dance, closing his eyes and throwing all his nervousness to the window, he lost himself in both the music, and his brother’s body and scent engulfing him.
Before he knew it, he started to fully dance and grind on his brother, who had both of his large hand firmly holding his hips to control every movement, the friction of their bodies made Yoichi want to moan at the feeling. Everything was starting to blur, his whole body was on fire, and yet he sweated as if he had a fever.
He never felt anything like this before, Yoichi like any other hormonal teen, masturbated, even if he felt an incredible amount of dysphoria at his wrong body part, this still didn’t keep him from touching himself, so he knew how it felt to be always horny. But horny isn’t just what he was feeling right now, right now he felt a hunger unlike anything he ever felt, he felt empty, and he had a deep need to be full.
As the music ended Yoichi nearly fainted, if it weren’t for his big brother he would have fallen to the ground, he could barely stand, his legs felt weak, he was so hot, everything was too hot. He needed and needed something, but what?
« Whoa, hey be careful Yoichi, you had too much to drink, here let me help you lie down on the nest I made for you » his big brother gently lifted him up with his beefy arms like he weighted nothing and laid him down on the mattress filled with many soft blankets and pillows, that looked very expensive. Yoichi always loved soft things.
Yoichi sighed a bit as he tried to regain his senses, but he felt worse than before, why was everything so hot? He let out a small whimper, and he felt even more pathetic, his big brother will smother him even more now great.
Unsurprisingly, his big brother laid down next to him, and wrapped both of his arms around him, putting Yoichi’s head on his chest. Yoichi didn’t even try to fight the cuddle, he felt like his skin was on fire, and the throbbing sensation on his crotch felt even worse, but at least skin contact with his brother lessened the sick feeling. How weird.
« Isn’t it nice to be cuddled against each other like this? I could spend an eternity being like this with you » his big brother let out a content sigh, as he started rubbing circle on Yoichi’s hip.
Yoichi lost count of how many times he felt creeped out by his brother tonight, why didn’t his brother have a girlfriend or boyfriend? Yoichi pitied any future significant other his brother would have but right now he was exhausted of being treated like one. What’s even worse is that he felt more like a prized possession to be hidden away than a sibling. Yoichi always thought that his brother used him as an outlet because that jerk was single, but now he was starting to think that his brother was even more insane than he suspected.
When he started to suddenly feel fluttering kisses on his neck, Yoichi let out a moan, and the fire on his skin felt even more dizzying. His neck has always been a sensitive spot.
« Someone is sensitive tonight huh? » with a dark chuckle his brother grazed lightly his sharp teeth on his neck, and then a hot tongue started to lick his earlobe and Yoichi nearly blacked out at the stimulation. He didn’t even have the mind to comprehend what his brother was doing and the consequences it could bring to their relationship, he was delirious with pleasure, he needed moremoremore….
Yoichi whimpered when he started to suckle on his neck, already leaving some dark hickeys on his pale skin.
« Yoichi you really don’t know what you are doing to me » He said between feverish kisses, « You don’t know how much my self-control is tested when I’m near you, how much I want to ruin you, to claim you as mine » he moaned in his ears, Yoichi could feel his brother’s huge bulge and unconsciously started to grind his ass on it.
The friction felt so good, when his dress was suddenly ripped, he shivered and keened when his brother started to pinch his exposed pink nipples, stiff because of the cold air.
“Look at how hard your pretty little tits are” with a smirk he then sucked hard on his right nipple while still pinching his left one, Yoichi let out a wail and arched his back. Every single touch his brother inflicted on him, made his skin burn with pleasure, it left him starving for more, Yoichi felt the inner walls of his hot cunt clench. He felt so empty, he needed to be full.
“Please Nii-San” Yoichi pleaded; his green eyes filled with tears streaming down his flushed face.
He only hummed in response, hot tongue trailing from his nipple to Yoichi’s stomach, Yoichi trembled, feeling even more tortured with arousal.
Finally taking pity on him, he said “Please what Yoichi? Could you elaborate? I can’t read your mind you know » his brother’s finger started to touch his wet folds, rubbing slightly his clit, making Yoichi whimper, and grinding himself against the large fingers, but his brothers retracted his hands away, Yoichi really wanted to scream in frustration.
« Please Nii-San fuck me, fuck me i need your cock pleasepleaseplease… » his brother went feral at his pleading, ripping any remnant of clothes on Yoichi and himself.
He spread Yoichi’s leg and positioned himself against Yoichi’s pink pussy, gently rubbing his cockhead with the wet arousal of the cunt, and he suddenly shoved his cock inside, making Yoichi screech, clawing at his brother’s back
He started to fuck Yoichi with a brutal pace, the only sound filling the room was the wet slap of skin on skin, Yoichi’s pleasured cries, and his brother’s grunts.
Yoichi felt so full, his walls were gripping his brother’s cock, and the heated lips of his brother on his neck only made him overstimulated with pleasure, his legs shook with every pounding of the hot rod buried deep inside of him
“Do you feel that baby? Do you feel how deep my cock is buried inside your little pussy? God you are so wet for me…You’re mine, mineminemine…” His brother babbled, and started to kiss him deeply, spit leaking from their locked mouth, he could feel his brother’s tongue reaching inside every part of his mouth
If Yoichi was coherent, he would be disgusted by the dirty kiss, and he would have made fun of his brother’s babbling during sex, he was always someone who monologued at every opportunity. Most importantly Yoichi would be disgusted at himself for having sex with his own brother and enjoying it.
But right now, all Yoichi could focus on was the large cock buried deep inside of his pussy, and how much he wanted to come all over it, again and again.
He could feel his climax, pussy tightening even more on the cock, he arched his back as his brother rubbed his swollen clit with his big thumb and his eyes rolled back as he let out a wail and a sob, and he came hard, squirting a clear liquid everywhere.
His brother came at the same time as Yoichi squirted, deep inside his pussy, he moaned at the sight of his seed leaking of his baby brother’s swollen red pussy
“See how well you take my cock? You’re mine now, I will never let you go, never. You’re mine to own and to breed” he purred in his little brother ears, he looked fucked out of his mind, lost in the afterglow
“Yoichi, you and I will rule the world and you will be my queen. We will build our own perfect little family, and no one will get in our way, we won’t be like our worthless parents. If anything or anyone try to separate us or hurt you, I will destroy everything” All for one hugged Yoichi tightly resting his little head on his broad chest, Yoichi unconsciously snuggled himself to his brother’s warmth and listened to his beating heart and his villain’s rambling tirade, he slowly started to pass out, feeling completely helpless and not understanding what was happening anymore as he felt his eyes closing themselves against his will.
« What a prom to remember, right my love? » He heard his brother murmur in his ears before everything went dark.
