Step-Sibling Rivalry (Finn Wolfhard x Reader)

𝚆𝚎𝚍𝚍𝚒𝚗𝚐 𝙳𝚊𝚢𝚢𝚢

Y/n's POV:

" SHIT, SHIT, SHIT, SHIT,
SHIT!! "
I yelled going insane.
I was trying to find my necklace that I was suppose to wear for the wedding but NO!
Since it just had to go missing 2 hours
before the wedding.
" Y/n, relax. You'll find it. "
Finn says calmly, already all suited up,
leaning by the door frame while I was going hysterical.
As hot as he looked in a suit,
I still needed to find the stupid necklace.
" Don't tell me to relax, Finn.
Ughhh!
Where the fuck is it!?? "
I got more annoyed as I opened every make up bag of mine.
And it was getting hot in the bathroom as I stressed looking for the damn necklace.
" I'm gonna go check my suitcase again. "
I scoffed, brushing past Finn.
I kneeled down, checking the pockets, unzipping the zippers and digging through the pockets.
" Son of a bitch! "
I shouted.
" Okay, maybe I can help.
What does the necklace look like? "
I heard Finn say from behind.
" It's just a simple oval shaped
silver diamond one. "
I answered.
" Oh wait, does it have a thin chain? "
He adds.
" Yes, Finn. It does. "
I paused, trying to be patient with myself
and well....
" Oh you mean this? "
I turned around to him holding it up
by the chain.

" You ass. "
I say standing up.
I was about to grab it from his hand but,
" ah ah ah. "
He pulls it out of my reach.
Damnit.
" Finn! I am not in the mood to play around. "
I say jumping but I wasn't tall enough.
He laughs as I try to get it from his hand.
" C'mon Finn! The wedding is in 2 hours! "
I whine as he continues to laugh.
" Alright, alright! Just stop jumping. "
His laughter dies down.
" Here let me put it on you. "
Finn says, and with that I turn around.
Feeling the cold chain and the warmth of his hands
brush up against my neck.
" There. "
I look back, seeing a smile on his face.
" Thank you for putting it on me. "
I smile, giving him a quick kiss as I made my way back to the bathroom.
" Yeah thankfully I did or else you would've torn this hotel room apart. "
He jokes, standing next to me.
" You know how long the wedding it gonna be? "
Finn questions me.
" No I don't but it shouldn't be that long? "
I answer applying some lip gloss,
smacking my lips together.

" HELLO MY FELLOW CHILDREN! "
We see the bathroom door swing open, with Brand coming in, startling Finn a little.

" Hey Brand. "
I smile, trying not to laugh at Finn reaction.
" Well now look who still isn't really dressed? "
Brand says, eyeing Finn up and down since he was just wearing his white buttoned up blazer.
Finn rolls his eyes and walks out the
bathroom. Assuming he'd get dressed.
" Well you look very pretty Y/n. "
Brand smiles.
" Back off, Brand! "
We both hear Finn yell from outside.
" Thanks Brand, you don't look so bad yourself. "
I chuckle, fixing up some of my makeup in the bathroom.
" Right!?!? I feel like... James Bond in this suit!! "
He pauses, posing in front of the mirror like an idiot.
That's when Finn walks in.
He was all dressed, with his tie and suit fully on.

He looked so hot in a suit...
Wait is this a kink?

Brand freezes and starts acting as if he wasn't
doing dumb poses in front of the mirror like a kid.
" Whatever dude. "
Finn chuckled, making his way over to me.
" Yes, Finnagin. "
I look up to him.
" Nothing, I'm just admiring
on how pretty you are. "
He smirks, a smile growing on my face.
" Alright, everyone ready to leave? "
Brand says to Finn and I.
Since I still have to meet my mother in a different room to help her get ready at the other building.
" Yup! "
I say pulling Finn along from behind.
" Woah, slow down Y/n. "
He laughs as we got out the bathroom.
" OH I know what we should do before we leave. "
Finn stopped Brand and I
from walking out the room.
" And that's?? "
I ask, eager to know.
" How bout a shot of a little alcohol
before we leave, hm? "
He says holding up 3 shot glasses.
A shot of Vodka before the wedding?
I mean...
" I wouldn't mind? "
I hesitantly say yes.
" Uh-uh no. I don't think this is good idea. "
Brand backs out.
" Oh don't be a pussy. It's just a shot? "
Finn smiles pouring the third shot glass.
" Fine... "
My bestfriend giving in and takes the shot.
" Here's to love, here's to honor,
if you can't come in her, come on her. "
We clink the glasses, taking the shot down, my eyes widen as to what Finn said.
Brand on the other hand was speechless. He didn't even take his shot.
A sour expression on Finns face after the shot,
" What's wrong? "
" Nothing. "
Brand answers, taking the shot.
" Alright, whooo!
Let's go. "
Brand shakes his head, trying to avoid the alcohol
we just endured.

~ After The Wedding ~

We were in the car, on our way to the reception.
Finn sitting next to me and in front of us
were our parents.
The whole wedding was just amazing, everything went so smoothly and
my mom and Finn's dad were finally married.
" You kids okay? "
My mom asks us with a beaming smile on her face.
" Never better mom. "
I answer smiling.
" You know, ever since we've gone on this
trip, you kids haven't fought once.
How's that?? "
Finn's dad asks he rubs my mom's shoulders.

"We only had secretly had sexual feelings towards each other, that's all..."

" We made up, and figured we shouldn't be
fighting over little things. "
I replied, nervously laughing afterwards.
" Right, Finn? "
I nudge his shoulder.
" Uhm, yeah, yeah. "
Finn coughed, nodding his head a bunch of times.
" Okay well your mother and I are really happy you and Finn are finally getting along.
Oh and Y/n, if you wanna go back to the hotel.
Finn can bring you back, okay? "
Our dad re-assured us, I nodded.

We were walking out the car, heading to the room where the reception
was gonna be held.
" If you kids need anything, we'll be at our table.
Alright?
I love you both very much. "
My mom looking prettier than ever,
gave Finn and I a kiss and a hug.
We went our separate ways, and Finn and I looked for Brand.
Boy were there quite a lot of people...
I probably knew like 30 percent of the people who were there.
As we were looking for Brand, we eventually spotted him
sitting by one of the table.
" Guys! You're here! "
My bestfriend happily stands up from his chair.

We sit and chat there for awhile, watching some video montages that were
being played on a wide screen projector.
That's when music started playing, people getting down on
the dance floor already.
" You wanna dance? "
Finn asks me.
" No thanks, I don't know how to. "
I laugh.
" We should get a drink or something?!? "
He says a little louder since the music was blasting around the place.
" Yeah! "
I say with a smile on my face.
" Ooh! I wanna come too! "
Brand says excitingly.
The 3 of us standing up from our seats and headed to the bar.

~ Few Moments Later ~

" Auhh Finn! "
I moan as Finn passionately kissed my neck.
We were in the gentlemen's bathroom, in a stall.
Finn pressing me against a wall, my hands squeezing his shoulders.
" Mmmhh! "
I bite my lip, trying to conceal the noises escaping my mouth.
" Ssshhhh, Y/n. Try to keep it down.
Anyone could walk in. "
He whispers in my ear in the most pleasing voice.
" It's hard to do that
when you're doing this to me. "
I whine, my eyes closed as I still continued to bite my lip.
" I told you to keep it down.
You wouldn't wanna get caught now, do you? "
Finn seethed through his teeth and he stopped kissing my neck.
" Don't- "
" You're just gonna make this harder for yourself baby. "
He teases, that classic smirk
slapped across his face.
He stops and he suddenly pulls the bottom of my dress up.
" Finn, what are you- "
" Hush.. "
He starts palming me through my clothed pussy.
" Finn- Oh fuck- "
My head once again tilted back, my hand
moving down to stop his.
" No, Y/n. "
Oh I knew he was smiling as he said that.
He grabs my hand, pressing it against the wall, interlocking our fingers together.
I feel lick my thigh, his tongue making its way to my underwear.
He bites the side, pulling it down with his teeth.
His breath tickling me as he breathed,
his long wet tongue circling around my wet clit.
" Mmhh, Finn- don't- don't stop! oh! "
A quiet moan escaping my mouth.
This was definitely the alcohol kicking in...
I try closing my legs but it was no use..
Finn would always find a way to keep them apart...

God I hope we don't get caught.
