BRINGING THIS BACK BC IT'S FIC THREAD TIME

sunny wakes one morning, blinking in the filtered sunlight through the curtains by the window. did he sleep in? it somehow feels later than usual. mari would usually wake him up. speaking of mari..... https://twitter.com/tsuki2tsukii/status/1346822721896812546

he turns to where her bed is, next to his, with only a bedside cabinet to separate them. she was not there. the disappointment felt like a punch in the gut. his favourite part of waking up was that mari was always the first thing he sees, either by her waking him up,

or him waking up first and seeing her in her bed next to him. but then something caught his eye, a figure in the corner of the room. sunny turns his head slightly to get a better look and his breath gets caught in his throat.

mari is there, by the clothes rack, except she was in just her underwear. her long, ebony hair cascaded over her shoulders and down the front of her body, filling even the space between her legs, and exposing her bare back. her skin was smooth, and, and.... /beautiful/

sunny squirmed under his blanket, his thighs rubbing together. he felt a funny feeling below, something tingly and weird. he continued to watch his big sister from his bed as she reached behind her back and grabbed the ends of her bra, attempting to pull and hook them together.

his hand lightly pressed against his crotch. ah, it was poking his palm through his boxers...the more he watched, the hotter his face grew, the more tingly the weird feeling became. everything started to look red, and through the haze of this sinful, puberty induced lust,

he swore he saw an eye open on the back of mari's neck, unblinking, watching him. staring into his soul, judging him. caught him red-handed. /i know what you're doing you sick fuck/ sunny heard it say in his head. sunny squirmed more. he should look away. this was his sister.

but he could not avert his eyes. everything about mari kept them trapped there. and the eye's stare grew more and more intense. /you think mari would forgive you for this sin?/ it said, and sunny whimpered in response. mari had just managed to finally clasp her bra together,

when she heard sunny and spun around.
"oh, sunny! you're awake!"
the eye was gone, replaced by mari's warm and gentle smile. but sunny's cheeks grew red and he could finally avert his eyes. she was still in just her underwear....

mari tilted her head, confused about sunny's reaction until she finally realized it was because she was still not dressed properly.
"oh! oh my gosh, i'm so sorry sunny!" she exclaimed and quickly grabbed a simple dress she could easily slip on.

"you just looked so peaceful sleeping there and since we had no rush to be anywhere, i thought i'd let you sleep some more while i changed..."
mari would usually change in the bathroom while sunny would change in the room. the wardrobe they once shared in their childhood became

sunny's entirely and mari got a clothes rack to put hers on, set up in the corner of the room. her parents insisted on finding another cupboard for her, but with how busy they were and everything, they just never got around to it. mari didn't mind, though.

"s'fine..." sunny muttered. mari grinned.
"well, now that you are awake it's time to rise and shine!" she exclaimed, rushing over to sunny's bed and grabbing the blankets.
"n-no.... five more minutes..." sunny mumbled, pulling the blanket back from her.

"come on sunny, up you get!" mari kept tugging at the blanket and after a few moments of tug-o-war, mari was victorious and managed to pull the blanket off sunny and towards the end of the bed.
"n-no!" sunny exclaimed, one hand his crotch and the other reaching out to the blanket

just out of reach. tears pricked the corners of his eyes. now mari could see it and she was going to hate him.
"sunny? what's wrong? you're- oh..."
yeah. she noticed.
"i... i'm sorry..." sunny sobbed, arm covering his eyes.
"aww, no, sunny..." mari sat on the edge of the bed

and leaned over her baby brother. to see him cry like this broke her own heart. she cupped his cheeks and gestured him to take his arm away from his eyes.
"it's okay," she whispered soothingly and kissed his tears. "this is normal for boys your age."

"n-no... but this time... this time i..." sunny couldn't say it. he couldn't dare admit that mari caused this. that he looked upon his sister with enough lust that it caused him arousal.
"was.... was this my fault?" mari asked. sunny, who had his eyes closed, suddenly shot them

open and shook his head frantically. mari twisted her mouth and shifted her eyes to side in thought, her hands still cupping her baby brother's face. then a thumb moves to gently caress his cheek, wet from the tears.
"oh sunny, it'll be okay." she said.

"you don't have to feel ashamed. do you want big sister to help?"
sunny's eyes went wide again, but he didn't know how to respond.
"if... if you want to handle it by yourself i can leave." mari slowly got up but without thinking, as if it was automatic,

sunny reached out and grabbed her wrist, preventing her from going. she looked at him with surprise, but smiled as she sat back down then.
"okay. let big sister take responsibility then." mari's hand then reached out and gently touched sunny's bulge with the tip of her fingers.

sunny twitched and whimpered and mari cooed at him. her hand wrapped around it through the fabric of his boxers and she rubbed slowly. sunny grunted and squirmed, gripping the sheets of his bed. he looked at her and wondered, had she done this sort of thing before?

like with hero? a pit of jealousy bubbled inside him. he knew they were dating, he wasn't so sure why he was jealous. guess he felt it didn't seem fair hero got to know, got see parts of mari that he would never. she was his big sister. it just didn't seem fair!

and knowing that mari had probably done this sort of thing with hero too... if sunny didn't love hero so much, he would probably hate him for that.

mari stops rubbing to hook her fingers under the waist band of his boxers. she looks at sunny expectantly.

"is it okay?" she asks in a soft voice. sunny inhales, tenses, then relaxes and nods. mari hesitates, as if to make double sure, and then she pulls down his boxers, revealing his arousal. the air in the room felt cooler than in his pants and he shivered at the exposure.

mari reached out her hand towards it again and rubbed. sunny shuts his eyes tight and groaned. he couldn't open them, the pleasure he felt didn't allow him to for some reason. but he wanted to see, wanted to watch everything mari was doing to him.
