Note: another valentine's day LOL (did not plan for it, but it ended up happening anyway xD)

Brig bros kinda vibe pic ^^^^

The sound of sick girlish giggles ecoed through the multiple cubicles of an antique and less used girl's bathroom:

"I can't wait for Law-senpai to try my valentine's chocolates!" - She continued giggling all by herself.

(I'm a HUGE fan of Yandere Simulator <3, this is my favourite song! Would've put it in the chapter before but couldn't find it on time :c )

Reader's pov:

I groaned, visibly tired, for the third time as my stomach growled so loudly it silenced the teacher, again.

"Let's end here for today class. It's clear we won't be getting anywhere with miss (Y/N)'s stomach getting in the way." - The teacher sighed in defeat and the class cheered.

It was almost lunch time, 20 minutes to be precise, but of course by now it wasn't just me who was hungry, everyone in class was, I could see it as they shoved their things inside their bags before storming out of the classroom.

I too was among the savages that ran through the hallways, creating an earthquake simulator, and rummaged the cafeteria for food, stepping over people if needed.

Once my stomach was full I finally regained my sanity and relaxed against the table, beside my best friend who just finished eating her burger and was now eating the left over fries on her plate.

"Pst! (Y/N)! Look who's here!" - My bff whispered with fries on her mouth with an amused look.

I lifted my eyes and followed hers until they landed on the cafeteria's door, where a croud of hungry senior students stood. Among them was my stupidly hot step-brother and his two perverted best friends:

I slammed my head against the table and groaned in frustration as I felt my cheeks start to burn.

"(Y/N) and Law-kun sitting in a tree! K-I-" - I slapped more fries on her mouth before she could finish her teasing.

I hissed at her as she made disgusting kissy faces with her mouth still full of fries, a gross sight.

"Stop! It's never going to happen..." - I told myself in disappointment.

"C'mon don't be like that! I'm sure-"

"It doesn't matter! Even if we could society would never stop judging us." - I looked at him go over and stare at the food for a long time, getting shouts to pick and move on from people on the back of the line - "So picky..."

"But fashionable." - My best friend pointed out.

"You mean ridiculous. Who wears different weird hats everyday and has the audacity of going against school clothing protocol and literally wear nothing but a jacket, just for fashion! In this cold ass weather!" - I gasped dramatically many times as I ranted and glared at my brother's back.

"Someone sounds jealous!" - She sang with a smug grin on her face.

"Of what? Having bad taste? Being flat as a pancake? Certainly not me!" - I defended myself but knew my face was deep red.

"PANCAKES? There were pancakes before we got here?!" - We turned around to find Penguin, one of my brother's bff, crying - "Damn! You wild animals couldn't even leave some for us seniors!? We work hard you know!?"

"Whatever you say grandpa." - My bff laughed while I scanned my surroundings, quickly finding my brother and his other bff beside him.

I turned around, trying to hide my blushing cheeks, not being able to look him in the eyes. 

My friend noticed this and made mall talk with them to cover for me, but throughout the entire lunch I felt his intense stare on me. I tried sitting there, not uttering a word, while my friend finished her fries and girls came over to give their valentine's chocolate to my brother and his friends, as soon as she finished eating I dragged us out...

I hated to admit but I was possessed with jealousy, that's why I stole all of my brother's chocolate's from his desk during the afternoon break and was now throwing them at our fireplace back at home. I didn't bother giving an excuse for skipping the last classes, I was filled with rage...

There was only one box left to burn. 

I took it in my hands but was unsure if I should. Guilt ate me inside out and my brain started overthinking of the possibilities, would brother be too angry? Would he even find out? Most definitly... Should I give him just this one box?...

Too many questions and no answers. So I did what I usually do when I'm stressed: I eat.

I ate the whole box, and it was quite big. I was sure I'd gain a 1kg or 2.

I shrugged those thoughts away and decided to finish my daily shores...

Law's pov:

I was never one to show affection for others, much less reacting to other's affection towards me. 

The chocolate boxes were a waste, I hate sweets, plus I'm studying to be a doctor, I know how bad those things are for our bodies, but I knew not to be rude in front of a girl. My parents raised me to be a gentleman after all...

The only positive thing I got from them was the amusing sight of my jealous sister. I like to think that it was because she was jealous of me being hit on by other girls, not because I received chocolate, something she loved.

(Y/N)-ya and I are not real sinblings, which I'm glad for. I could never face my family again if she were my real sister, the girl I had been jerking off to for the past 2 years.

I consider our new family junction a blessing and a curse. A curse because no matter how unrelated by blood we are people will never accept us if we were to ever be together. And also a blessing because I always have good excuses to peep on her showers, tease her about reading her diary, going through her undies, etc. But best of all going late at night to the bathroom and getting on the wrong bed by 'accident'.

If only we were a little bit younger I'd be able to make up an excuse to shower with her...

Unfortunantely, that's not how the world works.

Earlier at lunch she stormed out, dragging her best friend with her. It worried me for the rest of the afternoon, especially after all of my chocolates disappeared and a teacher came to ask me where my sister was, since she skipped her class.

I know she's not on her period yet, I keep tabs on it. She also doesn't have any doctor appointment otherwise my dad or her mom would've told me, plus her bff refused to talk.

I hoped she'd just be sulking somewhere and that nothing bad had happenned to her and went home after school ended.

I played dumb when people asked me about her, I didn't want rumors to spread, people could be nosy and mean...

I locked the door after getting in, seeing a thin layer of water fall down the stairs. I glared at the top of the stairs and threw my bag on the sofa before dashing upstairs.

The second I opened the door more water came out. I cursed at my sister's sleeping body on the floor, still fully clothed.

"Damn it (Y/N-ya)!" - I picked her up and put her on the bathtub, too focused on the problem.

Quickly I turned the water off and ran to our storage room. I had to clean her mess before our parents came home!

Thirty minutes forward and the floor is all clean and shiny, only needing a few minutes to dry off completely, looking like we had outdone ourselves in our shores.

(Y/N)-ya owes me a big one...

Speaking of (Y/N)-ya, I remembered I left her on the bathtub but she was no longer there and the floor I just scrubbed was wet again with small puddles.

I groaned in annoyance pulling my hair softly, not wanting to go bald. That woman will be the death of me!

I dried the floor as I followed the trail of water into my room. The door was open and on top of by bed, hugging my pillow as she stuck two fingers inside herself was my very naked hot step-sister.

I felt my face burn as she eyed me and kept pleasuring herself, this time moaning louder and clearer my name. (I love flustered Law <3)

I felt my pants starting to get tight as I approached her horny figure. I picked up her wet clothes from my floor and quickly went to her room and put her clothes to dry by her window so it wouldn't be too obvious when our parents came.

Then made my way back with one of her towels and put it over her.

"That's enough (Y/N)-ya..." - I gulped as I pulled her hands away, together, restraining her complaining self and short of cocooning her in the towel before picking her up.

I took her back to the bathroom, looking back to certify my bed would dry someday, and put her back on her feet once we went inside the bathroom.

Locking the door, I stepped back and watched as she glared at me with a pink face and pouty lips, throwing the towel to the ground and stepping on the floor with a loud groan, just like a child...

"Have you been drinking?" - I asked trying to focuse only on her angry face instead of her naked body.

"Look at me!" - She yelled, her hands folded into fists.

"I am."

"No, you're not. Look at me! As a woman!" - I stepped back as she stepped closer.

She then took my hands in hers and put them over her breasts. I couldn't help myself and kiss her as I squeezed her boobs gently.

Her body felt too warm, she was definitely under some influence.

"What did you drink?" - I asked breaking the kiss.

She glared at me and as she was about to scold me again I massaged her breasts some more, a bit rougher this time, making her moan.

"Answer me or I'll stop." - I warned her and she nodded.

"Juice." - She moaned leaning her head back as I pulled her left nipple and flicked it.

"Food?" - I leaned closer to her, my body wanting her warmth.

"Burger... and fries." - She laid her forehead against mine as she tiptoed to kiss my lips.

She gasped at me picking her up and pulling her into my lap, against my hard crotch, lacing her legs around my waist.

She placed her arms around my neck, feeling my back muscles as we made out.

At some point in our make out session she started grinding her crotch against mine and I had to sit down over the toilet cover.

"No chocolates?" - She flinched and it was like a knife had sliced the air, killing the mood.

(Y/N)-ya glared at me, even bared her teeth at me but then started crying, hidding her face in shame, yelling stuff like 'You're a player', 'You only like those whore who give you chocolates'.

I sighed, still not comprehending how she could possibly be in this state after eating chocolates...

"I don't like sweets." - I simply stated and hugged her, placing butterfly kisses over her neck and jaw.

This seized her cries and replaced them with moans instead as I kissed her tears away.

"I salty things instead. And those whores could never compare to my little sister." - I finally was able to kiss her lips - "What about you (Y/N)-ya? What do you like?"

The mood came back as she eyed me down and got up from my lap to get on her knees in front me. She proceeded to unbutton my pants, open my zipper and pull my pants and bxers all the way down before licking my cock like ice cream.

I was so flustered and overwhelmed with her bold attitude I couldn't help myself and stare at her working her way on me, holding her hair up.

She licked everything, even my balls, she then took one by one and sucked gently on them for a little while before going back for my hard cock, waiting for her to pit it completely on her mouth.

She, of course, couldn't take all of it at once and had to use her hand to help stroke. She gagged a few times, her stubborness showing as she did not give up. I decided to help, thrusting inside her mouth.

She moaned and took her had away as I pulled harder on her hair, each time going faster. She seemed to enjoy, so I took this as my chance to fuck her pretty little mouth as hard as I could.

I felt her grab my thighs, pulling them away, but I didn't let her. Soon I came in her mouth and she coughed for a good 3 minutes, spitting cum all over the bathroom floor.

I soothed her by touching her bare back in circular movements. Once she was better I pulled her into my lap again and walked us both to the bathtub, where I sat us in the warm water.

I reached for her boobs as she laid her back on my chest, she reached for her core, spreading her legs above water as much as she could, but intead of screaming pleasure she screamed in pain as my penis went inside her.

She felt so good, so warm inside, it was strange, but wonderful. I thought I could stop myself, but fuck, now I needed my sister, I needed to eat my little sister's pussy!

I gripped her tight by the chest while my hips worked wonders against her tight ass.

She squearmed a bit not liking it at first but quickly changing her mind, going limp on me, leaving me to toy with her however I wanted.

For better access, I pulled her up by the knees so they'd be against her shoulders while I sat up and kept piercing her from behind.

The water turned slightly red as I took her virginity without pity, thrusting into her with as much force as I could.

Our moans finally become one when we reached the orgasm. I almost fell backwards from fatigue, but couldn't waste this opportunity...

I let her legs go and pushed her torso forward so she'd be on all four. My hands gripped her ass cheeks and spread them as two fingers came to scissor her anus while I, once again, fucked her vagina.

I put my free hand around her waist and sent it to her clitris to masturbated her and replace the momentary pain with pleasure.

I kept going faster as her moans increased. I felt her walls starting to get tight around my member and played faster with her clit, helping her reach her second orgasm.

Once that was done I took myself out of her and went for her second pinky hole, waiting for me. This time I went very slow, knowing how much more painful it was.

(Y/N)-ya even cried a bit, if it weren't for her lasting orgasm it would have been much worse.

In the end I couldn't bring myself to hurt her more than I already had, so despite being halfway in I still did her like that, bit by bit trying to go any deeper, but stopping once she begged me to.

Not long after I came inside her and she came for the third time.

"That's enough for today. We'll try it some other time." - I kissed her forehead and she nodded.

The both of us clearly exhausted.

I quickly cleaned us both and put us in her bed, since mine would be wet for a long time, only putting a pair of boxers on and a small transparent summer pyjama I could clearly feel her up with no problem.

We slept spooning, me being the big spoon and her the small one, with my hands over her breasts and cock pressed on her ass.

Later that night:

"Oh my..." - A copy of (Y/N) as an older woman in her late 40's gasped as she peeked inside her daughter's room - "Rosinante, you didn't tell me Law still wets his bed!"

"I thought he didn't?..." - A tall man behind her, also peeking, said.
