Notes
     I'm not sure where I'm going with this. This was supposed to be a one
     shot but I got more ideas than I planned on and now who knows how
     long this is going to be but thank you, Autumn for putting up with my
     whining and encouraging me to write/post this. You da best. My time
     skips are horrible so sorry if there is any confusion. Harry and
     Louis are full blooded siblings so if this story isn't up your alley,
     please DO NOT READ. Additional tags are to be added later so just
     bear with me.
     Sorry for any mistakes but I hope you enjoy!
     Thanks x

“Harry, stop it.”
Louis sighs for the umpteenth time as she tries her hardest to focus on the
homework laid out in front of her, chewing on the end of her mechanical pencil.
She has been trying to ignore the obnoxious giggling coming from the other side
of her brother’s wall for an hour now but it’s no use. His friend is loud and
Harry knows studying is a lost cause because the noises aren’t going to quiet
down any time soon.
She is happy of course that Harry is home for the summer, quite the fan of her
big brother, but with him being home, that meant all of his old flames showing
face around the house, hogging all of Louis’ quality time with him.
She tries to tell herself she isn’t jealous and that she just has to be patient
because Harry is home for a few months and she will get her much needed sibling
time eventually but her resolve is short lived because the noises on the other
side of the wall are back and this time they’re more than just little giggles.
She sighs once more, putting her earbuds in.
                                       _
“Lou, you up?” Louis is a little disoriented when she hears the sound of a soft
voice in her ear.
“Mm- Haz?” Her blue eyes blink slowly, trying to adjust in the dark room before
they settle on the broad silhouette that is her brothers. “What are you doing
in here?” She yawns, trying to get herself to wake up.
“I wanted to see you of course.” Harry’s laugh is soft and quiet and it makes
Louis’ tummy flutter as she offers her brother a sleepy, shy smile she’s sure
he can’t see. “Don’t think I forgot about my favorite girl.”
And it’s words like that that make Louis forget all about the other girls
because her brother has explained to her countless times that those girls mean
nothing to him and at the end of the day, his heart is hers.
“I didn’t want to bother you earlier when your friend was over, so…” She trails
off, and Harry only shakes his head, leaning down to press a soft kiss to the
pout on her lips.
“You wouldn’t have been a bother, love.” But they both know that the unspoken
rule is Louis is not to disturb Harry while his friends are over so she only
shrugs in response. “Can I lay with you?”
Louis is already nodding and scooting over to make room for Harry before he can
even finish his sentence, always up for spending time with him. He chuckles
quietly and slots his larger body into the bed beside her under the bohemian
designed comforter.
“Did you have a good day?” Harry’s lips brush against the soft strands of her
hair as he speaks, his arm around her and his fingers running up and down her
side making her shiver a bit.
“T’was alright,” Louis mumbles, getting lulled back to sleep by the gentle
sound that is Harry’s heartbeat. She feels so happy, having him right here with
her and she lets herself dose off some with the sound of Harry’s heartbeat
thudding gently in her ear.
Harry only hums and watches his sister with fondness he reserves for her and
her alone. “Sleepy, baby?”
“Yeah, Haz.” And she’s whiny now because he keeps talking to her and she just
wants to enjoy laying with him without a care in the world.
So he lets her, holding her close as he kisses the crown of her head and falls
asleep with her.
                                       _
Having sex is the hardest part for them. Louis struggles to be quiet late at
night when Harry pays her a visit and he struggles with being gentle because
she's just so submissive and eager to please, and he can't get enough.
Louis’ hands scramble to grip onto her sheets, a soft whine leaving her mouth
as she presses her face into her pillow while she feels Harry lick hungrily at
her sex. He holds her up by her hips, her back dipped as she pants harshly into
soft fabric, struggling to be quiet.
He makes her feel so good and she is just so smitten and helpless to her
feelings.
“Harry,” She mewls as he pushes his tongue into her again and she wonders how
anyone could be so skilled with their mouth.
Harry pulls away from her for a moment, pressing a soft kiss to her bum,
parting her cheeks some and pressing a teasing kiss against the puckered hole
there, making Louis gasp and sit up some.
“Wait-”
“Shh,” Harry scolds, forcing her back on her belly, giving her a soft swat on
her backside in warning, making Louis stiffen and go quiet. “You know better.”
She only nods, not sure if he sees it but he continues on with his motions,
going back to his original target and tonguing at her sex a bit longer before
he’s up and lining up with her.
He had just been teasing her; knows she isn’t ready for that step just yet.
Louis lets out a barely contained noise as Harry begins to spread her open with
his cock, the adolescent trying to keep her body relaxed at the initial
stretch. The sex was pretty recent, Harry having just started making love to
her a few months ago when he came home for spring break.
They had been fooling around for over a year but it was when Louis turned
sixteen earlier on in the year that Harry really started treating her less like
a curious child and more like a young woman.
“That’s it, baby, take my cock,” Harry’s voice is gentle and reassuring,
knowing Louis needs to be distracted from the slight discomfort of the stretch.
She likes to focus on Harry’s praises and he doesn’t mind giving them when
she’s being a good girl.
“Ah-” She bites back a yelp when Harry suddenly rolls his hip, her cheeks
bouncing a bit as he presses against them with his hips.
“You like that?” Harry’s suddenly blanketing her with his body and Louis can
only let out a little whimper at the feel of his lips brushing against her ear
while he begins to pound into her smaller body.
“Y-Yes - I-” Suddenly his hand is over her mouth just as Louis lets out a
squeal when Harry goes harder. He loves to wreck her, but she needs to be
quiet. Their parents are just down the hall, blissfully unaware of what their
son does to their little girl at night.
Harry makes Louis do things girls her age have yet to even dream of, bending
her in this position and that. She takes the pounding for a while, being so
good, only to let out a soft breath of relief when her brother eases up a bit
and then pulls out. He was making a mess out of her, Louis’ body overwhelmed
with pain and pleasure as she lay flat on her mattress.
“Alright, on your back, sweetheart,” The low and gritty sound of Harry’s voice
makes Louis obey, her eyes heavy lidded as she lays on her back.
She was a lot more filled out than most girls her age, her curves coming in
nicely. Jealousy coursed through Harry’s veins, thinking of all of the boys she
probably attracted unknowingly.
His little Lou was so sweet and oblivious and although he knew he wasn’t one to
really talk, he’d be damned if he let some guy just come around and prey on his
baby girl.
“Harry,” Louis is breathless as she feels her brother push into her again, her
knees to her chest as he leans over her and keeps her in place, thrusting into
her over and over again. Her tummy is tight and she knows tomorrow she’ll be so
sore but she doesn’t care right now.
Right now, she feels so good and absolutely full.
“Such a good girl.” Harry pants. “You’re so good for me.”
They’re at it for quite some time before Louis comes with a silent cry and
Harry follows shortly after.
Louis loves when Harry comes home.
                                       _
“Your brother is so gorgeous,” Louis rolls her eyes as she listens to Niall go
on and on about Harry, the blonde unable to help it as she watches Harry mow
the lawn from Louis’ window. They’re just hanging out, her, Louis and Zayn as
they lounge about in her bedroom.
“Niall,” She huffs, trying to pass her irritation off as disgust. “That’s
gross.”
Niall rolls her eyes, not bothered. “Oh come on, Lou, don’t tell me you haven’t
noticed. You’re so lucky you get to see that fine piece of ass everyday.”
And Louis knows this but the last person she needs to be reminded of how
attractive Harry is is Niall. If her friends think he’s attractive shirtless,
they should see him naked.
“Anyways,” Zayn butts in, looking up from his phone and at Louis who is sat
cross legged on the opposite side of her bed. “You’re coming to the party Liam
is throwing tonight, right?”
Louis nods because of course she’s going. “Niall needs a wingman.” She says,
making Zayn chuckle and Niall pout. She’s only been trying to get Liam Payne to
notice her for forever.
Niall grins, unashamed. “Your parents are out for the night, right?” She asks,
wanting to make sure they have a place to crash.
Louis nods, getting up and padding over to her closet to get an early start on
looking for an outfit. “Yeah, so you can stay over too, Z.” She says over her
shoulder, her friend nodding her head slightly.
She wants to spend the night in with Harry, but knows she can do that tomorrow.
Niall will murder her if she bails on them.
“Lou,” The trio barely has time to look at Louis’ door before Harry is opening
it without even bothering to knock, shocking her friends.
He’s just as Niall said, gorgeous of course, as he stands there, chest
glistening with sweat and hair pushed back out of his eyes by a thin bandana.
Louis tries not to stare at the muscles he has on display.
“What’s up?” She asks him, not noticing the way her friends stare at her like
she’s gone mad. She usually throws a fit when her parents try to enter without
knocking.
Harry nods at her friends, eyes lingering on Zayn a bit longer, before he turns
to Louis. “I just wanted to let you know I’ll be out for the night so if you
need anything, you have my cell.”
Louis frowns then. Sure, she was going out, but Harry didn’t know that. What if
she had wanted to hang out?
“Oh, okay.” Is all she says, turning back to looking through her closet so
Harry doesn’t see the annoyed look on her face.
“Be good, I love you.” And then he’s gone and the three teenagers are left in
silence before Niall speaks up.
“Damn.”
                                       _
“I can’t believe he asked for my number!” A drunk Niall is over the moon as
she, Louis and Zayn all stumble up the sidewalk to her house. They’re all
giggling, even Zayn as they brush against one another and make their way inside
once Louis fishes out her spare key from her bra.
“You looked hot tonight, Ni!” Louis slurs. “Even I wanted to get your number.”
She giggles, teasing of course.
“You know you-” Niall cuts off with a hiccup as she struggles to kick off her
shoes. “-you’re my one and only, Lou bear!”
The three laugh once again and Louis only leads her friends up to her bedroom
after locking the door, the three thankfully not having to be quiet since no
one was home. They undress shamelessly around each other, all very comfortable
and at ease in each other’s presence.
“Alright, Nialler, time for bed.” Louis coos to her chatty best friend after
slipping on a baggy tshirt she stole from Harry to sleep in.
“Will you be the maid of honor at mine and Liam’s weddin’?” Niall slurs and
Louis has to laugh because she’s just so fond of her Irish blonde.
“Of course, Niall. I’d be offended if I wasn’t your maid of honor.”
Niall is all smiles after that and Louis giggles when she finally lets sleep
take over. She tucks her in and looks up at Zayn when he calls her name softly.
“Let’s go out back for a smoke.”
Louis hesitates, still new to Zayn’s sudden love for pot, before she nods,
realizing she’s not that tired. The two make their way downstairs and out onto
the back deck together, Zayn already pulling out his little stash and small
bowl as they sit at the small picnic table in Louis’ backyard, side by side.
“Did you have fun tonight?” Louis glances over at Zayn briefly with a small
smile, before she’s looking back up at the sky.
“Mh,” She hums. It was a really nice night. Not once did she think about Harry
and she was grateful she didn’t have to spend the night at home, alone,
pretending she wasn’t sad.
“Good,” Zayn nods and takes a hit of his bowl, before passing it to Louis who
blinks at the little object in uncertainty.
“Here,” She’s grateful when Zayn shows her how to take a hit, the bowl pressed
to her parted lips, Zayn showing her how to position her fingers before she’s
taking a deep hit, only to end up having a coughing fit.
Louis wants to strangle her best friend when he laughs, gently patting her back
while she continues to cough harshly, blue eyes wet with tears and glaring.
“I hate you,” She croaks when she finally catches her breath and Zayn only
chuckles again, taking another hit.
He’s so much cooler than anyone she has ever been friends with and watching
Zayn effortlessly blow out the smoke in the shapes of little rings reminds
Louis of just how amazing he is.
She’s easily impressed, sure, but Zayn is two years her senior and he has girls
and guys lusting after him all the time at school. And yet, he enjoys spending
his time with her and Niall, just hanging out, not really doing anything,
Zayn is wonderful.
“You’re staring.” Louis blinks, realizing Zayn was talking to her and she was,
in fact, staring.
“Oh,” She normally would flush and stutter out some type of response and
awkwardly change the subject, but all she can do is giggle like an idiot.
Louis is high.
Zayn smiles at that, nodding his head in approval. “Nice.” He comments and
Louis feels pride well in her, happy to have gotten Zayn’s acceptance.
“So whatever happened to Perrie?” The subject is random and it’s rude of her to
ask about such private things so abruptly but she’s cross faded and her usual
good girl filter is gone.
She grins when Zayn laughs, passing her the bowl. He has such a nice laugh.
“Easy,” He says when she takes another hit, this one a bit easier than the last
but she still coughs a bit instead of letting rivers of smoke flow easily out
of her mouth like Zayn does.
“Perrie, huh?” He brings Louis back to focus on the conversation she had
started, the young girl blinking slowly at her best friend. “Nothing really.
We’re casual.”
“Casual?” She asks, and Zayn nods.
“We fuck around but it’s nothing serious.” He elaborates when she only blinks
at him.
“Ah, and Gigi?” She’s feeling bold and Zayn can tell. Niall is usually the one
to try and pester him, Louis usually shushing her and scolding the Irish girl
for being so intrusive.
“Casual.” Zayn answers her easily, not bothered by her questioning one bit. He
thinks it’s cute, seeing Louis act so out of character.
Louis looks thoughtful and Zayn watches her a moment. He’s always thought Louis
was a beautiful girl but she was a little too sweet for his taste.
“What about you?” Louis looks up, and Zayn enjoys seeing her blue eyes red
rimmed and unfocused. It’s an odd thing to admire but he’s pretty gone himself
so he can’t help his admiring.
“Me?”
He nods. “Anyone special?”
Louis pauses, hesitates, and then shakes her head. “No.” She says softly and
Zayn thinks about calling her out on her weak response, but he’s not as bad as
Niall. Won’t bug her about it, even if he’s a bit curious.
“Want to try something?” He asks some time later, wanting to change the subject
when he notices Louis has gone incredibly quiet. He can’t tell if it’s because
she’s stoned or if she’s still mulling over his question but once again, he
doesn’t ask.
“Okay.” Her smile is sweet and trusting and Zayn blinks, a bit surprised at how
beautiful she looks like this, hair tousled and over her shoulder, in just a
large t-shirt as she sits there straddling the table seat, bare thighs on
display. When did she start to look so mature?
 
“C’mere,” Zayn’s tone is gentle and Louis obeys as she eases forward a bit,
watching curiously as he takes a hit of the bowl before leaning towards her.
She doesn’t even flinch when his mouth presses against hers, instinctively
parting her lips and breathing in the smoke he releases. His lips are soft and
chapped and it’s so intimate but it only lasts a moment and then they’re
pulling apart and Louis is releasing the smoke, not coughing this time.
They watch each other a moment and Zayn briefly realizes this is probably the
most cliche set up he has experienced in his life but -
“Can I kiss you?” He asks before really thinking about it and the shock runs
through both of them as Louis nods her head some, her tongue swiping over her
bottom lip before she can stop herself.
Zayn hesitates, before he sighs, smiling at Louis to calm her and then leans
forward.
Louis has never kissed anyone other than Harry so she’s nervous at first, but
once she sees the soft smile on Zayn’s face, she can’t help but relax a bit, a
small smile of her own forming as she leans forward to meet him, and then
they’re kissing.
At first, it’s just the soft brush of lips and Louis swears her ears are
ringing as she waits for Zayn to deepen it, but he doesn’t. He keeps it smooth
and simple and then he’s pulling away.
And Louis is… disappointed?
Zayn looks at her with a knowing smile, reaching up to gently grip her chin,
thumbing over her bottom lip. “Next time it’ll be better.”
Louis is in awe as she stares at Zayn, her heart thudding harshly in her chest
and she can only nod her head some, receiving one last lingering kiss from her
best friend before he’s pulling back and gathering the bowl and bud up.
That night when she’s in her bed next to Niall, Zayn being the gentleman he is,
sleeping on the floor, she tries to squash the guilt she feels when she thinks
of what just happened.
I’m sorry, Haz is her last thought before she falls asleep.
