Step-Sibling Rivalry (Finn Wolfhard x Reader)

𝙷𝚘𝚝 ( 𝐕𝐈𝐈 )

Y/n's POV:

The photo was a mirror pic of him,
in the bathroom, it looked like he just
got out of the shower.
He was fully naked with his towel covering his crotch area, exposing his slim hips
and his v-line.

Immediately, I felt my cheeks heat up.
Not knowing what to do...
I just saved the photo, put it in my hidden photos, then left him on read.
I'll just comment about it when we see each other.

I couldn't stop looking at the photo...
Fuck, he's so hot.

I finally controlled myself and remembered that I needed to pack my hoodie and a pair of my sexy bra and underwear. In other words, lingerie.
And yes, it was for me to bring in the trip
but it was in the laundry...
Great now I'll have to fucking do it.
I checked my phone for the time; it was already 2:48 in the afternoon.
I sighed and went to my hamper
to get my hoodie and my lingerie for
you know what.
I then headed out and saw Finn's
bedroom door open.
I looked in and saw his packed clothes in his black suitcase, oh and he wasn't there.
Probably still in the shower?
I chuckled walking out and into the
laundry room downstairs.
I was walking down the stairs when,
" Y/n? Honey? "
My mom poked her head out her door as I took
a few steps back.
" Yes, mom? "
I asked, hiding the lingerie.
" Are you doing laundry? "
She pointed to the basket.
" Yeah, yeah I am. "
" Great! Uh, could you be a dear and fold some clothes? Just leave them in the laundry room when you're done. Here. "
She walked out handing me some of her
and dad's clothes.
" Yeah sure. "
I nodded and headed to the laundry room.

I put the delicates and my hoodie in the washing machine, added some dish soap and
stayed in the laundry room, waiting for it to finish.

It's been a few minutes or so,
so I decided to fold the clothes my mom gave me while watching some YouTube videos
on my phone.
I suddenly heard Finn shouting upstairs, I stood
by the door frame to listen better.

" MOM! Where's Y/N?!? "
He yelled, sounding like he was coming out of his room.
" She's in the laundry room, Finn!! "
I heard my mom's muffled shouting from her room.
" Kay! THANKS! "
Finn shouted, hearing his footsteps
coming down the stairs.
Making me jump, leaving the door slightly open,
and went back to folding the clothes.

I heard the door creak open, and yes
it was indeed,
Finn.
" Y/nnn."
Finn whined wrapping his arms around
my waist as I was folding the clothes.
"Finn."
I mocked,
removing his hands from my body, taking my phone to stop the video that was playing.

Why did I do that exactly?
Cause our parents were right upstairs!
Knowing what would happen next if he continued.
As much as I liked this,
I couldn't risk it...

" Oh, c'mon Y/n. I know you like this.. "
He then gripped my hips pressing
himself against me.
" You feel that? "
Finn asked as if I couldn't feel his huge boner
against my ass.
Fuck..
" Feel what? "
I asked knowing that it was only going
to make it worse.
Finn pressed even harder, and grinded hard against me again, basically pushing me
over the dryer.
" What about that time?? "
He taunted, bending over my back as I was
still face down on the machine.
"Finn."
I chuckled, trying to not get distracted
by his boner...
" You know-"
Finn cut me off,
" Know what, Y/n? "
He said teasingly as he continued to grind
on my ass.
" You- You know we can't? Besides I still have to fold some clothes Fi- ahh!  "
He thrusted in making me let out a moan.
" Fold them later, You know
you want this. "
He growled in my ear still firmly keeping me
in place underneath him.
I let out a breathy moan, feeling a sudden push
making my underwear uncomfortable with
dampness.
