Step-Sibling Rivalry (Finn Wolfhard x Reader)

𝚈𝚊𝚢!!!...

Everyone was done eating lunch,
and well our parents told us to meet them
at the beach.
Since we went back up to the hotel room.
On the way to the room Finn and I wouldn't stop saying what we think they were gonna tell us,
And even until now...
" If they find out then they find out. "
Finn shrugs as he goes on his phone, tired of this conversation.
I can't blame him since I was too, but
my overthinking-ness was fighting against it.

" Finn, we can't be laid back about this.
They're gonna kill us...
Better yet, probably disown us... "
My eyes went wide as I paced back and forth
in the room.
" Y/n, you're being delusional. "
He laughs shaking his head.
" How!??? "
" They'll be mad at us for sure?
But I don't know about "disowning us".
Besides they just got married." 
He quotes and he was actually making a point.
I'm probably just over-reacting...
But there are so many bad possibilities that could happen...
One of them being-
" They'll probably send one of us away, Finn.
Therefore, we- we won't be able to be near or together. "
I say, thinking that if this is what they're
gonna tell us.
I could lose, Finn...
I turn my head to him only to have his eyes wide.
" What? "
I say in concern.
" Nothing. I just- I didn't...
I didn't think of that... "
He stops scrolling from his phone,
sitting up on the bed.
" Well, think of the good ones..
Maybe they're just gonna tell us on how happy they are about
the trip or something. "
He stands up from the bed, seeing his tall lanky figure take his shirt off.

Ummm...

" Y/n... "
I faintly hear.
" Hm?  "
I hum in response,
my eyes only focused on him.
" Y/n... Quit mesmerizing.
You there? "
Everything was a blur besides Finn, seeing that he was coming towards me.
" Y/n. "
" Wha- What?
I'm- I'm not. I'm not... "
I lie, furrowing my eyebrows as I looked down.
" Mhm, sure. "
That stupid smug smirk starts to form on his face.
" Okay no- stop!
I'm serious, Finn.
What are we gonna do if they find out. "
I whine plopping on the bed , laying flat on my stomach and smushing my face into a pillow.
" Baby, relax.
It's probably not it. "
I felt the bed shake, feeling Finn lay next to me.
" But what if it is? "
I say through the pillow.
" What? "
" But what if it is? "
I say, my voice still muffled.
"  If it is, then...
We won't let that happen. "
I turn around facing Finn, our eyes immediately locking.
" If they ever send one of us a way.
Or disown us, which I doubt.
I won't let that happen.
Okay?  "
He re-assures me while he brushes some hair off my face.
" You sure? "
" Yes, Y/n. I'll do anything if it only means
I get to be with you. "
A smile creeps up on his face.

" God I love you, Wolfhard. "
I almost whisper as I go on top him,
straddling his waist.
Pulling him into a kiss as soon as we both
got comfortable.
Giving each other small pecks while we laugh.
Moving back every time he tried to turn the kiss into a make-out, teasing him
in a sort of fun way.
I feel him get hard under me, slightly grinding my hips a little.
" Stop, moving, away. "
Finn laughs, trying to pull me in closer.
" Why don't you convince me to? "
I smirk, my hands wrapped around his neck while his were
strongly gripped on my lower waist.
" Oh don't even try to test me out, Y/n. "
His voice being deeper than usual, laughing as I try to move away from him,
but as always he would be stronger than me. 
I feel his hand make its way to my ass, gripping it as he pulls me closer to his body.
We hear someone knock on our door, and not long after it opens-
" Guys we gotta- "
It was Brand who stepped in...
" Oh c'mon, everytime!! "
Quickly he turns around facing the door, having this the second time
he's walked in on us doing, well stuff...
Finn and I stop, looking at each other then laughing.
" Now what's so funny?
And one of you guys put a shirt on! "
Brand yells annoyed.
" You're just jealous you don't got a girlfriend yet, bro. "
Finn answers back.
" hey, I'm not!
I just find it weird that you guys are technically brother and sister! 
And that you have to be doing stuff
when I go in the room!- "
" We're not even related! "
I say over Brand's words.
" Jesus, dude. Calm down. "
Finn slightly shouts, causing Brand to stop.
" It was a joke, not a dick?
Don't have to take it so hard.
Right, Y/n? "
Finn asks me as I try to hold in my laugh since I felt a little bad for Brand.
" You guys are really funny, you know that?
Ha, ha, ha, I am laughing so hard, I cannot breathe. "
Brand says in a straight monotone voice,
which only made it harder for Finn and I
to stop ourselves from laughing.
" No Brand, you just have the worst timing. "
Me saying that ended up making Finn laugh.
" But all seriousness though, we gotta get goin.
Both your parents actually asked me to come up here and call you guys down already. "
Brand says, making me worry about what they're gonna tell us.
" Alright, c'mon. "
I say getting off Finn, putting my shoes on.
I hear Finn say, him scooting next to me by the edge of the bed.
