Step-Sibling Rivalry (Finn Wolfhard x Reader)

𝚆𝚑𝚊𝚝 𝚍𝚘𝚎𝚜 𝚑𝚎 𝚖𝚎𝚊𝚗? ( 𝐕𝐈𝐈𝐈 )

Y/n's POV:

I wiped my legs, cleaning myself up but,
I couldn't stop thinking about what he meant by,
"Oh also, send me one back."
I was confused, but my thoughts snapped out when the washing machine timer dinged.
I pulled my now-wet underwear and shorts up.
I kept thinking of
what Finn said while I got my hoodie and
undergarments from the washer.
The dryer didn't take long, so as soon as it finished,
I went upstairs to my room and packed the lingerie in my suitcase, and my hoodie by my
dresser for tomorrow since it was snowing.
"Oh also, send me one back."
Kept repeating in my head again as I lay down
in my bed.
What does he mean?
THEN IT GOT TO ME!
" Shit. "
I whispered to myself, then
I googled some poses for ideas to send a
photo back.
I decided to take a shower so that I won't have to shower tonight.
I headed to the bathroom and took a bath.

Once I was done,
I prettied myself up and attempted to
take a hot photo.
The photos I took weren't fully nude, though my tits were slightly out,
but my left forearm covered them.
And my leg covering my pussy, exposing my ass
to the side.
I faced the mirror, sort of sat on the counter, leaning back, and snapped several photos.
I chose the best one and hesitantly sent it to him,

Why?
Because he might not think it's hot or something...
Compared to his photo?
Fuck me...

Well I sent it anyway, and
he's seen it.
I got impatient waiting for his response.
He texted saying,
"Come to my room when ur done"
I smiled at his text message,
I wrapped the towel around my body and headed to my room to change into some sweatpants
and white tank top for pj's.
Once I was done changing, I headed to Finn's
room to knock.
" Come in! "
I heard him faintly shout.

" Hey. "
I smiled sitting on his bed, while he was still in front of his closet, packing.
" Seriously? You aren't done packing?
It's been like 2 hours since
mom told us to pack. "
I asked, folding a few of his clothes on his bed.
" Yeah, no... I was busy. "
He answered.
" Busy with what? "
I asked cluelessly.
" Fucking you in the laundry room. "
He smirked, taking clothes out
of his closet.
" Huh, smooth. "
I licked my lips looking down.
" Alright, I think that's all. "
He rested his chin on his hand, looking at the very few clothes on his bed.
" What? That's all you're bringing? "
I questioned him.
" Yeah? Is it too much? "
He raised an eyebrow.
" Oh god no! It's sooo far from
too much. "
I laughed standing up to look in his closet since there were like
2? or 3 shirts in his suitcase?

I scanned through his hangers,
pulling 1 or 2 more shirts out that were suitable for the beach.
And a few sleeveless shirts for him too.
I was looking for more, when this blue and white Hawaiian blazer caught my eye.

This was soo for the beach!

" Here, bring these. "
I set the shirts down, including the blazer
on his bed.
And he examined them, while I waited for a response.
" These, sure. "
He pulled out the shirts that were under the blazer.
" This, no. It's too girly. "
He argued gesturing to the blazer.
" Clearly. "
I answered getting it from the hanger.
" C'mon stand up. "
I gestured to him, and he groaned not wanting to but he still did.
I chuckled, fitting the blazer over his shirt.
" See, you look great! "
I smiled pushing him to his mirror.
" Eh? "
He looked down at me.
" What? It does look good!? "
I laughed folding it and putting it in his suitcase.
" Who said you could pack my clothes? "
He laughed sitting back down on his bed.
" Who said I couldn't? "
I questioned, bending down to
organize his clothes and stuff in the suitcase,
since it was pretty messy..
" Oh shit."
I turned back to see him checking me out.
I gave him a confused look,
we then bursted out laughing out asses off.

Out laughter died down and he then spoke,
saying,
" Oh about the picture you sent me?... "
I stiffened from his words.
" What about it? "
I questioned him.
" Soooo. Fucking. Hot... "
He closed his eyes, tilted his head back.
I then I looked down seeing a visible print
on his grey
sweatpants.
" Finn, your uh.. "
I looked down.
" Oh, eheh... What can I do? "
He laughed nervously.
I rolled my eyes.
" Finn, where's- "
Our mom opened his door.
We were both frozen...
Shit..
Finn quickly grabbed a pillow covering his boner before my mom could see or anything.
" Ooohhh!!!! You're helping each other pack! "
She said putting her hands over her heart, while
Finn and I agreed awkwardly.
" Anyways, just came in to give you kids
your tickets- "
Sh smiled setting them down by
Finn's night stand.
" Finn here's your ticket,
including yours Y/n. "
She then walked out closing the door.
Finn reached them from his bed and
handed me mine.

We examined the tickets, where we were indeed going to the Bahamas.
" You excited? "
I smiled sitting next to him.
" Yeah, only cause you're going. "
He nudged me playfully, while I blushed at his comment.

~ Time Skip ~

After helping Finn pack we were going over the
things he packed.
Just to be sure.
" Okay, your shirts and shorts throughout
the vacay? "
I asked sitting on his bed while Finn was by his suitcase checking the things.

" Yup. "
He replied
" Swim suits? Or what do you call em?
Swimming trunks?"
I asked,
" Mhm. "
He nodded.
" Pajamas?? "
" Here. "
" Boxers? "
" Yeah. "
" Suit for the wedding? And clothes for the after party? "
" Yeap. "
He replied popping the P.
" And your bathroom essentials? "
" What? "
" Like your vanity case stuff? "
" Oohh yeah, they're in here. "
He nodded a couple times.

" Alright.. Well Finn, I guess you're pretty
much packed. "
I grinned getting up from his bed.
" Thanks to you. "
He chuckled when I remembered something.
I started looking around the room to see if he packed his "on the go bag" like mine.
" What are you looking for? "
He questioned me.
" Did you pack a bag for the airport? "
" Noo?? "
" Jesus, Finn. "
I laughed.
" I didn't know there was an
airport bag that I had to bring??? "
He said, basically clueless.
" Wait what do you mean? "
He raised an eyebrow, leaning on his bed frame
" Like things you'll need, for when you're
on the plane. "
I smiled leaning on his door frame.
" Oohhh, then no. "
He huffed a laugh.
" Well what stuff are you bringing? "
I asked, knowing it probably would be a lot,
making a very visible grin on my face.
" Uhh, extra condoms for trip. "
He smirked making me smile but,

Fuck...

It slowly turned into a frown.
We never used condoms..
Oh shi-
" You okay? "
He asked.
" We- we didn't use any... Finn. "
I stuttered, getting a little scared.
" Fuck, you're right, we didn't... "
He rubbed his forehead.
" Let's go to the store, we'll buy uuhh...
What's it called?
Plan B? "
He said, not so sure of his answer.
" Yeah, birth control. "
I chuckled, as he made a disgusted face.

I can't believe he finds birth control gross when sex is probably worse.
I chuckled at the thought.

" Wait how will we get there tho? "
I asked him.
" Walk? "
He answered and I nodded.

" But.. All seriousness though, Finn "
I laughed.
" What are you actually going to bring. "
I continued my sentence.
" Um, maybe my earphones, phone,
wallet, and- "
He stopped and looked at me.
" What? "
He chuckled.
" Told you, ya need a bag for the airport- "
I started walking off to my room.
" -Anyway, don't worry, we'll just share a bag. "
" Yeah, yeah. Okay. "
I heard him say from behind.
" Just come in my room tomorrow morning before we leave. Okay, Finn? "
I smiled looking back at him.
" O-Okay. "
He mirrored one back and started
walking towards me, I stopped walking
He looked down at me and pressed his soft lips
on mine,
without any hesitation, I kissed back.
He pulled away, smiling like a 5 year old that
just got a lollipop.
" When should we go to buy the thing? "
He smiled keeping eye contact.
Uhmm??
" Later? After dinner? "
I said.
" Okay, just text me. "
He walked back into his room, me
doing the same.

A smile beaming on my as I closed the door.
" Ugh!! I can't wait for this fucking vacation!! "
I shouted.
" AHHHH!! "

I laughed afterwards, then m laid in bed and stayed on my phonewaiting to be called for dinner.
