Step-Sibling Rivalry (Finn Wolfhard x Reader)

𝙱𝚛𝚎𝚊𝚔𝚏𝚊𝚜𝚝 𝙵𝚘𝚛 𝙳𝚒𝚗𝚗𝚎𝚛? ( 𝐈𝐕 )

" You are such a fucking cunt! "
Finn yelled.
" Go fuck yourself, you damn prick."
I screamed back, hitting the wall that connects our bedrooms.

Currently, I am STILL arguing with Finn.
On the brink of killing him...
Why?
Because for some UNKNOWN reason he would tell the guys
to stay away from me!
In other words, not to ask me out or some shit?!
He said he was just
"looking out for me" which I know is a shit ton of lies,
making me HAVE NO FUCKING CLUE AS TO WHY HE'S DOING THAT!?

" Fuck you, Finn! MY LIFE IS NONE OF YOUR FUCKING BUSINESS! "
I was gonna shut my bedroom door but,
" YOU CAN'T TELL ME WHAT TO DO! "
He shouted making me make my blood boil...
All of a sudden, we hear something fall downstairs.
Finn came out of his room as did I,
and we looked at each other then ran straight down he stairs.
" What in the actual fuck is the matter with you two!? "
My mom shouted, holding her hand that was bleeding.
First time hearing her curse?
" What uh- what do you mean, mom? "
Finn asked in a soft voice crossing his arms.
Asshole...
" I mean the fact that you two are constantly
arguing and yelling!?
I was trying to get a dish out of the dishwasher and it shattered it because
you both scared the hell out of me with the
god damn screaming! "
She seethed through his teeth.

She was beyond pissed, she never gets angry so this is something
that we don't see much of.
Finn and I looked down at our feet, in shame.
" I'm sorry mom. "
I mumbled barely looking up to glance at him.
" I- I'm sorry too... "
Finn said, then mumbled
" -That your daughter is such a bitch! "
My blood began to boil again at his words.
" Fuck you, Wolfhard! "
I said through gritted teeth.
" No, fuck you, Steele! "
He retorted turning his attention towards me.
" Why? Just why do you have to be such a raging asshole
all the fuckin time?!
Doesn't it EVER get tiring for that tiny brain of yours!? "
Rage came out of me way too quickly when it comes to him.
" Me?! I'm the asshole?! You-"
Finn started to yell at me, moving his hands around like a crazy person
but was cut off.
" I'm done! You kids are gonna spend time together
and you are gonna fuckin like it or so help me!
I will kick the both of you out! "
My mother yelled pointing at the both of us, her face turning red
out of anger.
We stood there shocked and quiet.
" Your father and I thought you kids could handle yourselves!
But since you two wanna act like idiots you will stay in the house
all weekend. No friends over. "
She went on, walking out of the kitchen.
" But- "
" No buts! "
She shouted going up the stairs to her room.
" Mother fucker. "
I whispered glaring at Finn.
He was already returning the glare, intensely.
I ran up to my bedroom, slamming the door behind me.
I called my best friend to tell him that we couldn't spend this weekend together.
It was ringing, and ringing until he finally answered.

" Hello? "
I sighed.
" What's wrong? "
He asked.
" We can't spend this weekend together... "
I said angrily.
" What, why? Why the fuck not?! "
He responded, returning the anger.
" Because of my jackass brother. We were arguing as always...
But this time it got out of hand and now my mom's making us stay in the house all weekend.
No friends just me and him...
We are going to kill each other by the time they get back. "
I rant.
" Did you ask him why he's been telling guys in school not to ask you out ,
or just leave you stood up on dates? "
" Yeah, he said he was "looking out for me" which is total bull
when he just makes out with that bitch Sydney who doesn't even fucking-
UGH! Never mind!
" Hmm. "
He says like he knows something I don't.
" What! "
I whined already knowing he's about to spit some truth.
" You. And. Him. Alone. All. Weekend. "
He retorted.
" Yeah and? "
I said obviously confused.
" God, Y/n.. When are you gonna quit lying to yourself and just admit
that you secretly like him.
And you guys argue so much because you can't do anything about it? "
" The fuck? You are sick!
Finn and I don't like each other.
You clearly know how much I fucking hate him! "
I said laughing.
" He's my step brother you fuckin weirdo. "
I added.
" Yeah, and that's the problem you both like each other.
I can see it the way you guys look at each other is so full of...
What's the word?
Sexual tension... "
My eyes went wide.
" I'm surprised you haven 't fucked yet to be honest. "
He says matter of factly.
I scoffed.
" I cannot believe you right now.
Yeah we might flirt the tiniest bit! But that-that' s nothing."
I said half truthfully...
" An- And sure I think he might be hot or whatever. "
I mumbled, playing with the fuzz on my blanket.
" But my hatred for him is- is so much more stronger
than anything!
I swear by it! Sincerely! "
I rambled on.
" You stutter when you're lying Y/n. "
" Fuck off, I'm not lying. "
" You always talk about how you hate Sydney.
His girlfriend... "
Brand added.
" You know I hate her as much as I hate him.
She's a total slut too and he deserves better. Not that I fucking care... "
" I always catch him staring at you in class Y/n. But you keep denying it! "
" That's because he doesn't! "
I argued back.
" Mhm well, I love you so very much but let me know how everything goes about, you know.
This weekend...
" Call you this Saturday."
He says winking, and I could hear the smirk in his voice.
" Bye, I love you too. "
I said then hung up quickly.
I threw my head back onto my pillow, groaning out of anger.
Maybe a nap will fix this shit going on in my head.
