Alternative Universe (AU): Moder time

Characters: Step-sister Reader, Adopted Law, Father Rosinante, Killer, Kid

Genre: Fluff (I think?)

Having an adopted older brother had to be the best thing that had ever happenned after your mother passed away and your father, Rosinante, went into depression.

Death took your father's smile along with her... He was not the same positive clumsy clown you loved, he was cold, too cold, a shell of a man and too focused on his work as a police officer to notice how much it had affected you...

Until one day school called because your grades went down, along with your social activity.

Your father knew he couldn't always be there for you so he decided to get you a three year older brother, Trafalgar D. Water Law, or Traffy as everyone called to his dismay.

Traffy appeared to be a distant cold hearted hot headed worldwide smart ass emo, who easily got annoyed at everything and anything, even mere objects.

That changed the day you came home crying because some girls bullied you, making fun of your deceased mother and zombie of a father.

Apparently Traffy didn't like it as he too shared the pain of losing loved ones, as you came to know later... He made sure they regreted it and apologized to you the day after, which you shamelessly loved!

From then on your relationship with him grew and you two became more than step-brother and step-sister, you became best friends, always together, protecting each other from bullies and the lonelyness that hunted you in those dark days...

You'd even bust each other out of class claiming family emergencies, prank the jocks and cheerleaders for all their bullying, set up your dad, Corazon as Law liked to call, with multiple women on online dating websites without him knowing... You were the couple people either loved seeing together or were terrified of!

In a blink of an eye years went by and both of you grew fond of each other quick, too quick, too deep... Deeper than your family status allowed... But both were too shy to confess...

Perhaps it wasn't just shyness but the fact that you both loved to tease and play games. Perhaps you both had realised each other's feelings and just didn't want to admit it or you just enjoyed a good chase...

Whichever the reason, you remained glued to each other throughout your teen years, savouring every moment together, with only your young adult years ahead... Before college begins...

Fake tears rolled down your puffy pink cheeks as your sobs ecoed inside your room. You sat against the headboard with your knees against your chest and sheets laid down on your feet.

The door burst open and a tall figure of a male teenage approached your crying one in hurry, not bothering to close the door.

"(Y/N)-ya! What's wrong?!" - He whispered as he hugged you on the side, rubbing your thigh in a soothing way.

"L-L-Law-niii..."- You half whined half cried against his hard chest - "I had a n-nightmare... again..."

His tired eyes searched for yours but they never found them as you were too busy cuddling into his defined chest.

"It's ok (Y/N)-ya... it was just a bad dream... It'll never happen..." - He sighed and kissed the top of your head.

You nodded and laid back down with a hand pulling him along.

"Sleep here, stay!" - You whined with your best puppy eyes.

Law shivered on the inside, for once he was glad his dark skin could hid so well his flushing cheeks... but not so well some other things, as you came to feel it poke against your back once he hugged you from the back while spooning...

You mentaly danced in victory as you pulled him closer to you by the upper arm, stopping right under your breasts so he could feel them. You knew what you were doing, you could feel him grow harder against your ass cheeks, which made you wet.

His body was tense at first, he was unconfortable and horny no doubt, but he came to relax and enjoy himself as he hugged you tight pushing your breasts up with his forearm and positioning himself nicely against your core, sandwished between your ass cheeks.

Your heart hammered against your chest, you wished he knew how you felt... that he'd feel the same way... so he could fuck you senseless right now.

"You don't need to be scared anymore... I'm here to protect you..." - His warm breath made contact with your sensitive ear, sending shivers down your spine, all the way to your big butt, who couldn't help but wiggle a bit.

The hand from the arm he used to hug you closer caressed your boob over your thin night gown in circles, as in a conforting way, almost exposing your hard nipple.

You kept your innocent pose with your hands together beside your head, taking deep breaths in order to calm your poor suffering heart.

"Thank you oni-chan. I don't know what I would do without you..." - Despite the guilt you couldn't stop yourself from saying it.

You knew your big brother's dream was to go to a good college and be a surgeon, but you didn't want him to leave. You hadn't even confessed yet! You couldn't imagine living without him! Or him living without you, far away, surrounded by sexy nurses! You just couldn't!

You noticed his change of mood once he stopped his work and simply hugged you as before. Suddenly you felt too guilty to continue and decided to get some sleep.

You woke up feeling cold and sore, as if a truck had dumped kilos of freezing snow on you!

You opened up your eyes and saw your big brother's head planted between your completely exposed breasts with your gown pulled down, as your body was now facing his.

You noticed he was hugging you with both arms and legs, as if he had become a koala during the night. A sight so cute you couldn't stay mad at him for letting you freeze.

You placed your hand against his raven spiky hair and gently brushed it to the side. These moments were the ones you'd treasure the most, when only you could see his fragile cute side...

Suddenly you felt a pull on your exposed skin, or more exactly on your nipple, which previously stood perked up beside Law's lips but was now between them.

He moaned against you and held you closer upon feeling your attempts to escape his bear embrace. He sucked harshly on your sensitive nipple like a child begging to it's mother for more.

You couldn't help but moan softly, managing to contain yourself a bit so you wouldn't wake him up. You chose not to resist and let him taste you as much as he wanted, massaging his scalp once more.

A few minutes later his body was more relaxed and felt much lighter on yours, his grip had softened as he felt calm and protected by your loving touch.

You sighed and smiled. What a big baby.

His movements stopped completely for a few seconds before he jumped over you, rolling you to the side so you were facing the ceiling with his heavy body hovering yours and his face right beside yours.

Correction: what a fat baby.

"(Y-Y/N)-ya..." - He moaned in his sleep gripping your shoulders tight in place.

"Law-kun, I'm right heEEEeeere!" - You whisper-yelled as he bit you neck forcibly and spreading your legs with his to stand in the middle.

"Mine..." - He bit and sucked your neck repeatedly while humping his crotch against yours.

"I-I-I'm yours! I'm yours!" - You yelled from the pain, not really caring if he woke up, you couldn't handle anymore bites.

He appeared to calm down at your shouts but still nibbled on your skin, slowly letting go and drifting off to sleep...

"(Y/N)-ya! Hurry, we're gonna be late!" - You jumped at your brother's banging against the door.

"Coming!" - You shouted back while tying your last shoe and grabbing your bag.

Quickly, you ran towards the door and opened it to reveal your brother's judgemental stare.

"What's the scarf for?" - He asked completely oblivious.

"I'm feeling c-cold!" - You tried not to bluch with the earlier memories.

"It's June..." - He narrowed his eyes at your scarf - "Take it off."

"N-No! I'm cold!" - You swatted his hand away.

"I don't care. Take it off!" - He grabbed your scarf in his usual mood.

"No!" - You slapped his hand hard in momentary anger but quickly regreted it - "I-I'm sorry!..."

Law didn't say anything, simply looked at you with what could be described as a 'murder look' and jumped on you with intent of taking it off of you.

He was fast but you knew him too well and made it on time, pushing him to the side in order to switch places and tripping him to the ground with you on top. 

You blushed not knowing what to say, unable to look at your big brother's wide eyes... while his lost themselves in something other than your neck...

"Y-You're wearing t-those to school?" - He asked while gazing at your flipped skirt and exposed white panties with your baby picture's together saying 'Big brother's' under.

You yelped in embarrassement pushing your skirt down and covering his eyes.

"Don't look! I forgot to do laundry!" - You fought him on covering his eyes.

"N-No way! They're so cute! Just like you!" - He laughed trying to peek.

"I'm gonna kill dad for making these!" - You huffed - "Don't make fun of me, you have a matching pair!"

"Y-Yeah..." - Law suddenly stopped mocking you while remembering when your dad first gave you them on last year's Christmas - "Our first couple's outfit..."

After composing yourselves you went to school, in a hurry, you were late!

During lunch a close friend came to visit!...

"Don't fucking speack to her like that!" - Your brother punched Kid in the face for saying 'Hi' - "In fact, don't even look at her! She's too good for the likes of you!"

And so another fight started...

"Wanna go get desert?" - Killer asked you.

"Yeah!" - You went with him leaving the other two to themselves.

On the way to the cafeteria you noticed Killer, who's usually the shy one, seemed a bit more talkative.

"S-So, (Y-Y/N)... I was wondering d-do you... You know this is my last year..." - He started awkwardly.

"Yeah, like my big brother!" - You pretended to be happy about the subject of it being his last year.

"Then you know... there's a thing called p-prom... right?" - He stuttered while blushing.

"Y-Yeah..." - Your mind wondered to who your brother would take, if he ever decided to go.

"I-I was wondereing i-if-"

"You could go with Kid? Great, it's settled!" - Law appeared out of nowhere with Kid pushing him against Killer before hugging you on the side and pulling your skirt up - "See this? It's my property! MY property!"

You yelped and slapped Law on the cheek along with his hands exposing your embarrassing panties.

"See this?!" - He pulled your scarf down showing them the hickeys - "Mine!"

"Ok-Ok! I get it!" - Killer shivered in fear using Kid as a shield.

"Good. NO ONE TALKS- No, no one LOOKS AT MY SISTER! Understood fuckers?!" - Law put his arm around your shoulders while shouting to the whole canteen.

Everyone stood shocked without knowing what to say, including you, well if you don't count a certain blonde crying and cursing in the corner...

For the rest of the day you avoided your embarrassing brother who was too stubborn to let you go even to the bathroom alone.

Once the day was over you returned home, where your dad awaited you after a long day of work.

"I can't believe you did that!" - You admited half mad half happy.

"What's wrong kids?" - Rosinante came from the kitchen catching you both by surprise.

"Dad! You won't believe what Law-ni did today at lunch!" - Your drama queen side was surfacing.

"Corazon, you won't believe what (Y/N)-ya almost did today!" - He stopped you from telling on him by interrupting you - "She almost accepted to spend a NIGHT with a BOY! An OLDER BOY!"

Corazon almost fainted.

Damn you had forgotten he was the queen of queen's!

"WITH A GOATE! AND LONG HAIR!" - Your father got up only to faint again.

"B-But you have-"

"(Y/N) Donquixote!" - Your father's dark aura surrounded you making you shiver - "I can't believe this! You are grounded for the rest of the year! And your brother's in charge! From now on you'll do everything he says and not leave his side!"

"But daaaaaad!" - You cried.

"No buts. Now go to your room, I'll call when dinner's ready." - He stated.

"I HATE YOU BOTH!" - You ran upstairs crying and slammed the door shut.

To be honest you were not upset at all, you just had to pretend to cry so they both fell at your feet and begged you to stop so their guilt wouldn't kill them. That's how men worked, at least the one's in your family.

You sobbed loudly, waiting for the footsteps to become louder and clearer, which they did. Soon they were right in front of your room.

You covered yourself with your blanket and curled up in a ball.

By the sound of the shoes and the weight on your bed it had to be him...

"I-I'm sorry (Y/N)-ya..." - You gasped, knowing how difficult it was for him to apologize to anyone - "But you have to understand, I can't let you be with any of those boys!"

"Why not?! You'll soon leave me anyway!" - You sobbed louder but on the inside you were doing your victory dance - "Go to your college girlfriends you hyprocite!"

"I'm not going to college for girls! I already have my own right here." - He hugged you over the blanket and it almost won you over.

"But you'll still leave..." - You pouted knowing it was true.

"I won't, not if my girl doesn't want me to." - He confessed.

"What if your girl wants you to go?..." - You tested guilty creeping in the corner of your mind.

"Then I'll spank her for being naughty and deceiving me and then I'll bring her with me." - Your head perked up from the blanket.

"What if she's too young to quit school?" - You looked him in the eyes.

"Then I'll go for a nearby college and still live with her." - He smiled.

"What if she doesn't want to get in the way of your dream?"

"She is my dream."

"What if she wants to go to prom?"

"Only if she wears a burqa."
