Step-Sibling Rivalry (Finn Wolfhard x Reader)

𝙴𝚟𝚎𝚛𝚢 𝚂𝚒𝚗𝚐𝚕𝚎 𝚃𝚒𝚖𝚎... ( 𝐗𝐈𝐕 )

Y/n's POV:

When all of a sudden,
Finn slightly lifts me up, and forcefully places me down onto his member making me let out a whine of pleasure.
He slowly started to move me up and down.
" Oh F-Fuck! Do-Don't... Don't go easy on me. "
I let out a breathy moan, feeling his hand travel up
the back of my neck then to my hair.

Feeling him slightly tug on them as I said that.
" Oh I wasn't planning on doing that.. "
He bit his lip, feeling the grip tighten on my head.
" Finn, I'm- Aauuhhh! "
I moaned as he slowly bounced me up and
down his lap.
" F-Fuck! "
His pace started getting faster.
" You like that? "
He groaned going faster.
Fuck! He's soo hot..
I looked up as I bit my lip, not answering him,
which was a wrong move.
We'll sort of?
" Look at me, Y/n. "
The hand that was on my hair was now gripped on
my jaw as he forced me to face him.
SHIT!

I yelped bouncing on his hard dick,
that kept going in deeper, and deeper and deeper...
Almost hitting my climax but..
He took me off,
making me sit next to him while I had my head back.

Why?

" Why- Why'd you stop? "
I panted as I turned my head to him.
" Nothing. Just lay here. "
He patted his chest making me a little disappointed,
since I was about to reach my climax.
I didn't do anything, I just sat there.
While looking up the ceiling, feeling the water move
since he scooted a little closer.
" Listen, I knew you were about to.
But I'm saving that
for later. "
He moved some bubbled away from my chest,
revealing my tits to him.
Feeling him rub and pinch my left one,
which made me go insane...
" Finn stop teasing. "
I put my right hand over his,
but he still continued.
" You can't tell me what to do. "
A smirk plastered on his face as he pinched
my nub harder.
" Aauhhh. "
I moaned traveling my left hand to my pussy to rub myself but,
" Ah. "
He stopped my hand, taking my wrist..

My eyes wide while his were full with lust,
we made eye contact for awhile until he sat up.
Bringing me along with him to the shower.
" What are- "
I was gonna ask but he covered my mouth,
walking closer making me move back against the showers wall.
Our hot naked bodies pressed against each other while he reached the nob to turn the rain shower on that was above us.
The hot water dripping on our bodies, making our temperature rise.
Finn caressed my arms, going down
to my waist and ass.
I knew we were gonna fuck in the shower,
since he was already aligning his dick
to my entrance.

Without any warning,
he thrusted completely.
" Aaauuhhhh!! "
I clenched around his cock, hearing him groan.
He lifted me up, pressing me against
the marbled wall as he fucked me.
His hands under my ass, squeezing them
every thrust.
" F-faster Finn. "
I managed to say while he pounded into my pussy.
" Fuck.. "
he gritted through his teeth.
My hands wrapped around his neck
while he sloppily kissed me.
Our tongues exploring each other's mouth,
feeling vibration on my lips as he groaned louder.
There wasn't much talking..
Only the sound of skin clapping,
while moans filled the bathroom.
He pulled away from the kiss, going at a much
faster pace.
Hitting my sweet spot.

Every... Single... Time...

" Mhm right there! "
I moaned catching Finn's attention.
" Uugghh Fuck! I'm gonna cum! "
I said barely able to speak between moans
as he continued to pound into
my tight cunt, feeling him in every
inch of me.
His wild soaking curls bounced
with anticipating with every thrust he gave.
" Do it... "
He panted.
" Fuck! "
I yelled gripping onto the back of his neck and arm.
" Cum on my dick, Y/n. "
He submissively instructed.
My eyes rolling to the back of my head as he thrusted into me one last time before releasing onto
his hard cock.
God, could this get any hotter?
" Oooohhhh. "
We both let out a breathy moan while
he stayed in me.
" Auhh. "
Finn breathing heavily, while we stared into each other's lustful eyes.
He slipped out, still firmly holding me
against the wall while I wrapped my legs
around his waist.
I closed my eyes, burying my head
into his neck feeling his warm breath on my back.
I was exhausted, but felt a certain amount of pleasure.
Fuck he's sooo good and knows what and what not do when we fuck...
This was our 4th time having sex
and he's never missed a spot.
Making me think...
I should do something pleasurable for him next time...
" I told you I wasn't going to go easy on you. "
I heard him laugh, feeing the vibration
as he talked.
I hummed in response.
" I know I said the next time we'd have sex, you'd give me a blow job but I'll let this one slide. "
He chuckled while he was about to carry me.
