Step-Sibling Rivalry (Finn Wolfhard x Reader)

𝙲𝚕𝚘𝚜𝚎 𝙲𝚊𝚕𝚕?

Y/n's POV:

" Y/n, could you throw the Doritos down? "
Brand asks, seeing his hand raised up.
I got the bag of chips and threw it to him.
We were chilling in our shared hotel room.
Finn and I were on the bed, while Brand was on a mattress on the floor.
It was around 5 in the evening.
 And later we're planning on night swimming up on the roof deck since we found out yesterday that there was an upstairs pool.  
" I'll be back." 
Finn turns around, going to the bathroom.
I eat some chips and continue watching the movie. 
3 - 5 minutes pass by when I hear Finn call out my name from the bathroom.
" Y/n! " 
I hear him shout again. 
" He okay? "  
Brand says with his mouth stuffed with chips. 
" I don't know? 
I'm sure he is? " 
I stand up from the bed, knocking on the door. 
" Finn? Babe?
You okay in there? " 
" Yeah! Just come in! " 
Finn yells once more.
" Okay. " 
I mumble under my breath, opening the door. 
Only to see Finn sitting in the bathtub all curled up. 
I gave him a confused look. 
" What are you?- "
" Close the door. " 
He says and I do so. 
Feeling the cold tiled floor as I made my way to him. 
Finn having one arm up, I go in the bathtub and sit next to him,
feeling him wrap it around me afterwards. 
" Now, what are we doing in here? " 
I say looking around the bathroom.
I really am quite confused as to why we're in here.
" You're so pretty? " 
He sweetly says, but in more of a question tone, as he simply ignored my question.
Tucking a few strands of hair off my face.
I could feel myself immediately blush from his comment. 
" You sound unsure? Am I really? " 
I playfully smile tilting my head to the side. 
" Yes! I- I mean yes, you are. You are. "
Finn going into panic mode, he gets a voice crack.
Laughing at his action, I still don't really get why we're in the bathroom?

Finn's POV:


Clearing my throat after having my heart stop for a few mili-seconds...
She looks so cute in that sweater and shorts that neatly cover that sweet ass of hers...
" Uh, what- what are you guys doing outside? "
I ask her.
" Nothing? Just watching the movie and well,
waiting for you. "
She lays her head on my shoulder, sounding unsure with her answer.
It was silent...
You could only faintly hear the movie playing from the room.
It started getting hot and I could feel her
staring at me.
I turn my head to look and she had the cutest smile on her face.
I smile back with my eyes closed,
hearing her laugh.
I feel Y/n move closer and scoot next to me,
feeling her put her warm hand
on the side of my face.
This was nice. I was feeling a wave of comfortness go over me
as I just sat in the bathtub with Y/n. 
We look at each other for a second...
Our eyes meeting in the middle.

Y/n, she pulls me in closer,
her eyes closing as she starts leaning in to kiss me.
Our lips brush against one another, neither of us wanting to pull away from this wholesome kiss.
She usually isn't the on to make the first move?
But it was cute being her bold enough to, knowing that
 she wanted me.
I lift my hand up and cup the side of her face,
giving each other small pecks.
She giggles, and I'm guessing my curls tickled her forehead.
I wanted to pull away to move this to the shower but she kept going. 
Her tongue synchronizing with mine.
I was already laying down, having her on top of me.
Hearing her hum into our kiss. Her hot, warm, and writhing body hovering over mine.

Suddenly we heard knocking from
the bathroom door, assuming it was Brand.
" Y/n. "
I mumble into the kiss, since she wouldn't pull away. 
" Y/n, wait. " 
I laugh, somehow getting her to stop.
She looks to me with warmest smile she has ever given me.
She so pretty-
Then there was knocking,  again. 
She looked to the side, the both of us facing the door.
" Y/n? " 
Brand continued knocking on the door. 
" I- I need help. The guy who delivers the food is here. 
And I- I don't know how much to tip him. " 
We hear him say from the door.
I hear Y/n sigh with her head down. 
God, can this guy do anything?
" You okay? " 
I say moving her hair out of her face. 
" Yeah, um. Just, stay here. "
She hops out of the bathtub. 
She then whips around, giving me a small peck on the lips.
" I love you. "
She smiles then makes her way to the door and  
I hear them talking outside. 

Now I was left here in the bathroom, waiting for Y/n to get back.  
 She was taking awhile, and it was getting hot so 
I followed her out after a few or so minutes.
I come out only to find the both of them outside?
 Anyway, I went to lay on the bed, get under the covers and find a different movie
for us to watch.
" Oh hey? I thought I told you to wait for me in the bathroom? " 
Y/n walks in, seeing her holding some drinks and some food in the other hand. 
" It was hot. " 
I tilted my head, letting a huffed laugh out. 
" Finn, want some? " 
Brand following behind her held out a closed box. 
" Whatchu guys get? "
I asked. 
" Wings. And there's some pizza
over on the table. " 
Brand answers taking a bite of some cheesy gooey pepperoni pizza as he sat back down
 on the mattress.
