#i was going to have it from reader-chan's pov but i wanted natsuo's self-hatred evident in the end

[whumperooni]

pls imagine that after natsuo decided to get revenge and became a fuckboy he also gradually started to get farther away from his cutie of a lil sister! he brings home some bitchy bimbos to fuck and doesn't even notice her anymore so little sister being the adorable thing she is, she becomes very upset and sad that her brother doesn't want her anymore, so who is better to take care of her then papa enji! i want to see natsus face when he realises his plan backfired in the worst way possible!

What else is a little sister supposed to do whenever her nii-chan abandons her? u.u

tw: incest, fuckboy!Natsuo, mentions of drinking and drugs

It starts with one drunk girl that doesn’t make it out on time before Enji can see her. Usually, Natsuo doesn’t bring women home- it feels like something he shouldn’t do; he can’t bring anyone back to that place.

(Not that he hasn’t had any other woman since entwining with you- how could he when he has such an adoring little sister to love and cherish and make squeal with pleasure? Why would he want anyone else?)

But that night? That night he just doesn’t care. Drunken from too many shots and too much cheap beer, he crashes with the girl he had somehow stumbled home with and, in the morning, he fucks her again through their mutual hangovers before sending her off to never come back again.

There’s a twinge of shame and guilt when he passes you in the hallway on the way to show his hookup out. Your wide eyes and disappointment prick at him like tiny needles, the pucker of your brow has him regretful. Whenever he nudges his hookup out of the house and comes back to you, asks you where you slept last night, the mumbled “Shoto-nii’s room” makes him feel even more guilty.

You only sleep in your brother’s long empty room whenever you’re feeling particularly lonely. Natsuo hates when you feel lonely- you should never feel lonely with him around.

He opens his mouth to tell you that he’ll make breakfast for you, that he’ll make up for last night, but he’s cut off whenever a gruff voice comes from behind him and says,

“Don’t bring whores into my house.”

In an instant, Natsuo’s regret gets flipped to rage- just the sound of Enji’s voice makes him want to snap and having him insult his hookup makes it even worse- and he glares at his father- mouth opening to argue only to be ignored as Enji turns around and lumbers off to the kitchen. He barely registers your shocked “daddy” that you gasp out- he’s too focused on his father and the annoyance that had been written all over the man’s face.

Fuck him, Natsuo thinks. Fuck. Him.

His anger is only quelled whenever your hand lightly, nervously touches his and he looks back at you to see your worried expression. It takes a moment for him to calm- lips pressing together and a long, deep breath needed- but he does and he swallows back his anger, his headache to force a small smile your way.

“Have you had breakfast? I’ll make you something.”

A mumbled thank you, nii-san and your fingers lacing through his helps soothe the rest of the lingering irritation. Natsuo tugs you to the kitchen and he tries to forget his father’s face and the satisfaction that had flicked through his anger over it.

He brings home another girl a month or two later. It’s not something he sets out to do, no.

But it happens. And the morning after is just about the same as the previous time- only with you more upset when you spot the hickeys all over the girl’s neck and Enji’s glare darker than before, his irritation more pronounced.

The third time is on purpose- something he seeks to do in a tipsy, vindictive rage after a particularly nasty argument with Enji.

He brings home another girl- someone dumb and sweet and just a little trashy- and he fucks her with the intention of making her scream for him, spending the night making her moans fill the estate.

You can’t look him in the eyes in the morning, but he feels no guilt- only satisfaction over the fury on Enji’s face and the way his hands clench and unclench from trying not to slug his son in front of his upset daughter.

Another nasty fight- one that you get caught in.

“-a goddamn disgrace. You think your sister needs to see this? How do you think this looks on me when you’re going around acting like a fool? I don’t know what the hell has gotten into you-”

“Daddy, please! It’s okay! Please don’t-”

“-I’m a disgrace?! That’s rich coming from you. You parade around acting like you’re so superior but all you are is-”

“Natsuo-nii! Please stop! Daddy doesn’t mean-”

“Don’t you turn this around on me, boy.”

In the end, Natsuo stomps off with red cheeks and gritted teeth- turning his back on his glaring father and his teary eyed little sister.

He stomps off and all he can think is I’ll show you a goddamn disgrace.

──────────────────────────────────────

Life for Natsuo quickly becomes a mess of clubs, hookups, hangovers, and arguments. With every girl he brings home, his father only gets more and more angry- fire bursting out in quick jets when he finds a pair of discarded panties on the lawn, some dumb slut eating at the table draped over his son’s lap, vodka bottles and condoms in the trash.

The fights get worse and worse. Natsuo starts staying away from home- only coming back to drag some girl home to rile his father up and to sometimes spend time with you whenever his guilt over your tears and upset becomes too much. He makes new friends with this new direction in life- crude boys he used to stay away from, men who fondle their girl’s tits right in front of everyone while talking about weed and parties and who has access to molly, who can get good coke.

They’re bad influences. He knows it. He knows.

But he doesn’t stay away from them. Soon enough he’s drawn into partying along with clubbing- weed and booze and more and more giggling sluts that want to ride his dick, suck him off.

One night he gets drunk enough to steal his father’s credit card and buy henny for everyone, weed and an obnoxiously expensive dinner, a solid gold chain that his flavor for the night talks him into buying despite Natsuo never wearing something like that before.

He doesn’t go home that night, but he ends up in someone’s penthouse and wakes up at four in the afternoon- classes missed and a whole block of time missing from his memory. It’s only when he checks his phone that he realizes what all has happened- snapchat showing him reeling and laughing, joking about his father’s money being blown.

It also shows him getting some sloppy head in some restroom he can’t remember. It shows him, too, that he had filmed a girl riding his dick- that he had spanked her ass and turned his phone around to show the world a drunken grin and bloodshot eyes, a gold chain around his neck.

Watching it is surreal. He knows that it’s him doing all those things, but he just can’t quite connect it at the same time. He’s never been into that stuff before- he’s never wanted to be into that stuff before. It makes something bitter and uneasy settle on his tongue, something uncomfortable weigh down his stomach.

He tries to ignore it and he checks the rest of his notifications- quickly swiping away Fuyumi’s worried texts and the messages on snapchat. There’s nothing from his father to be seen and that’s a relief that he pretends he doesn’t feel.

There is a little popup that sounds during his scrolling that shows that you’ve posted and Natsuo opens it almost absently, blinks whenever he sees a photo of a nice lunch captioned with Lunch with daddy💕

The daddy makes him scowl, but something in him twinges- guilt, a touch of sadness. He can’t remember the last time he talked to you, the last time he held you close. He used to be with you daily- hands holding yours, kisses pressed to your cheek and lips and forehead often, your cuddly body warming his late at night and holding him snug inside after a sweet ravishing. It’s been so long since he’s been with his little sister- it almost feels like that past affection had been a dream.

Guilt eats away at him and Natsuo runs his hand through his hair, buries his face into his palms after.

What have you been doing while he’s been fucking around? Sleeping in his bed because you miss him? Seeking comfort somewhere else- with someone else? Who has been taking care of you?

Your lunch post flashes through his mind and Natsuo feels sick then- knots twisting in his stomach whenever he thinks about who else you love in your life.

The last time he had been at home, you had clung to Enji- barely trying to break up the fight and sniffling through it, burying your face into your father’s chest.

You had clung to him then- are you clinging to him now?

Natsuo swallows and he stands from the bed, ignores the sleepy mumble that sounds off behind him.

It’s robotic how he dresses and drives home- sunglasses doing nothing to prevent a throbbing headache as he clenches the steering wheel and tries not to throw up last night’s indulgence all over his lap.

Getting home makes his stomach feel even worse, but he pushes it all down and forces himself to walk inside the house- mind racing as he tries to think of where you could be right now.

He finds out whenever he hears a loud gasp and a moan of “daddy.”

He doesn’t want to go. He doesn’t want to see. His body and mind don’t connect, though, and his feet move automatically- one in front of the other until he’s in the doorway of the kitchen.

There’s flour on the floor from where it’s been knocked off the counter. Plates in the sink and magnets on the fridge he doesn’t remember ever seeing. A new mixer tucked away in the corner and daffodils in a vase on the windowsill.

And there’s you too- perched on the counter with your apron and the skirt of your sundress flipped up, mouth open with a cry, cheeks flushed pretty and sweet as Enji curls his thick fingers inside your cunny.

“D-Daddy! Please! More!”

“Shh; I’ve got you, little one.”

Bile rises in Natsuo’s throat as he watches you mewl and arch- hands reaching for your father and lips pressing against his needily whenever he gathers you in his arms and starts to slowly slip inside of you.

“L-love you, daddy,” you sob. “Love you- please- please don’t ever- don’t leave me...”

“I will never leave you, little one,” Enji promises gruffly as he spreads you apart and makes you whimper. “Never.”

Turquoise eyes flit to the side and Natsuo freezes in the doorway whenever they lock onto his - heart breaking and shame flooding through him in thick, hot waves when his sweet, sweet little sister who he loves and has neglected begins to mewl “daddy, daddy, daddy!”

Tears prick at Natsuo and he turns from the kitchen- walks away with a hand covering his mouth and his body bent forward as he struggles not to heave.

He drove you into Enji’s arms. He drove his sweet, beloved little sister into the arms of the man he hates the most. He neglected you for what- bimbos and booze and petty revenge?

God, he’s so fucking stupid.

Natsuo stumbles into the bathroom and he grips the sink tight- eyes wet and bloodshot whenever he looks in the mirror, face pale and neck mottled with hickeys, the stupid chain mocking him as it shines in the light of the bathroom. Far off, he can hear you moaning and Natsuo grits his teeth as he glares at himself in the mirror.

He really is a disgrace.
