Work Text:

It was really good to be back home, finally returning back from college for more than just summer break. Finally being home and with a degree to show that Jiwon had been working hard. That time she spent cooped up in her dorm studying while everybody partied showed her strides. Though she wished she could’ve partied.

She made a bunch of friends that she inevitably would post to her instagram. They all followed each other in hopes they’d see each other again. Which was probably less likely then they’d all like to admit. She got her Bachelor in Arts… a heavy lean towards music. She would like to sing, in another world maybe she’d debut.

The ride back home was quiet, the uber driver’s car had a nice smell at least. The engine was loud, and she could swear she heard the exhaust pipe cough up smoke a couple times. She was a little upset that no one came to see her, but it was rather late… Hopefully they’d be up when she got home.

Once she got out, she grabbed her suitcase and dragged it to the door. She unlocked the door and braced herself for everyone to jump out but— No one did. In fact all the lights were out, and doors were shut.

Maybe it was a little better that way, saved her from constant conversation… And having to talk all night about her last year. Since she rarely stopped by and visited this time. Only coming back for longer breaks. It wasn’t intentional, she got so focused on graduating that she forced her dorm to be a cocoon. Making sure she slipped her shoes off at the front, she headed for her room.

Twisting the knob to her room, the sweet smell of home washed over here instead of anywhere else. Her hand flopped against the wall until it found the switch.

The ceiling light illuminated the small room, her room was relatively untouched. In the same spots from last time she visited. White shirt she left still hangs from the laundry basket. The full body mirror turned slightly to the left.

Relatively was the right word… Because suddenly she had a roommate. Her hair tied into a bun, resting within her bed. It was no other than Wonyoung, of course.

Jiwon gave her sister a gentle smile, she looked very at peace resting in her bed. Even though she had her own room, it was nice to see her after mainly speaking with her over video. She pleaded for Jiwon to come back as soon as possible. And she’d do anything for her little sister… so she got the first flight she could.

She was too tired to look for pajamas. And also too tired to unpack everything. She removed her jacket and threw it to the side, placing her suitcase on the side of the door in her already small room.

She dragged her joggers off her legs. Looked at her slim legs in the mirror… She hoped her sister didn’t mind her being in her underwear in the same bed. Flipping the lights off, she placed herself under the covers.

At first she faced her sister, her beautiful sleeping face… Was it weird to admire her like this? Her two moles, the way she kept her pretty lips closed… The small breaths she’d make, or how she used to giggle in her sleep. What am I thinking? She thought… Suddenly seemed out of place. And a little uncomfortable… She decided she’d turn to the edge of the bed instead.

 

Her drift off to sleep was very quick. She was completely worn out, and absolutely overworked when it came to the brain department. Once she touched the soft cushions it was practically over but…

Someone else was expecting her arrival. Wonyoung was awake the entire time, learning how to fake sleep was pretty easy. Being able to fool your parents? Not so easy… but your older sister?

She was glad Jiwon was finally home. She was very territorial of her unnie. She fought against the idea of her leaving for college. Even wanted her to take a gap year, it was very selfish but she didn’t care. All those days in school, she’d come home to a Jiwon-less house. She is eighteen now… Yet had no intentions of moving on.

Wonyoung waited awhile to make her move. Even laying next to her sister was giving her an erection. Yearning to be closer to the other. She slowly closed the gap between the two, silent moves as if she was a ninja.

She slid her hand under the cover… dragged her index finger down sliding it across the others thigh. Her skin was so cold, yet she welcomed it. If Jiwon was awake she’d admit this was borderline creepy.

“Unnie… I missed you so much…” She whispered, pink lips curved as she formed the sentence.

Constantly she wanted more from the other, she wanted to see more of her. Stalking her socials… keeping up with her following seeing she was making new friends.

Tugging at her boxers, her cock jumped out from its hiding place. She was sure it poked Jiwon’s ass, filling in the small space she left between them. Hands caressed that same aforementioned ass… Biting down on her plump bottom lip as she felt on the other.

Jiwon’s body squirmed a little, fixing the position she was sleeping in, slightly pushing herself up against the pillow. Wonyoung hitched her breath remaining completely still. Once the other was presumed to be asleep, the space between them closed.

The slightest creak on the bed chirped throughout the silent home. Wonyoung drooled at this opportunity, something she’s never done before. She had always enjoyed the satisfying feeling of getting off to her sister… Yet doing it right next to her? This was only the start of what she dreamed of.

Slowly she slipped her arm under Jiwon… Wrapping the both of them around her tiny waist, pulling themselves ever so closer. The little gap between her thighs seemed slightly open. And the perfect size for her.

She slowly inserted her cock between the gap, hot thighs rubbed against the tip before she slid even more. Plush skin felt nice to rub against, her slow made sure there was no sound of their bodies connecting.

Hot breath brushed down the other's neck. Curling into her body as if she could ever leave her in the current state she was in. The small and pathetic humps that were only followed up by her quiet lonely moans… Naturally Jiwon wasn’t always such a heavy sleeper, but the added condition of jet lag helped.

So close to each other she had gotten a whiff of her fresh shampoo, blonde locks that meshed perfectly with her crystal white skin. She wanted more of her, though the hot squeeze between her thighs was captivating. She picked up the pace, the smooth sound of her sliding against the bed sheets as her thigh burned against them as well.

She continued to breathe in Jiwon’s aroma, savoring it as if it was a meal. “Would Unnie… be upset at me if I came on her thighs?” She whispered into her ears… How she wished she could receive an answer, maybe even be scolded by her older sister.

Either way it wouldn’t matter, reluctantly she pulled out from in between the other thighs turning the other way and finishing in her hands, her eyes closed shut for a bit… The sticky fluid attached itself to her hand and spread across her fingers.

She made sure to wander to the bathroom after. Deep down she knew that wasn’t what she truly wanted… She would make sure she’d get her satisfaction, even if she’d had to beg for it.

After washing her hands she quickly attached herself to the other, arms wrapped around her waist and buried her face into her neck.

 

The morning eventually arrived, Jiwon of course woke up sooner than her sister. Eyes slowly opened, as she felt the warmth another stuck to her back like a leech. She tried to silently escape her grip without waking her. Gently pulling the arms apart that are attached to her waist. Sliding out from the bed.

Her body felt a little sweaty, especially towards her back area… She shrugged it off as a lack of a fan in the room as well as her door being shut. She took her pajamas with her to the bathroom and got ready for a shower.

Slightly turning the knob, hot water spewed out… The door she had closed slowly crept open. Instinctively she jumped to cover herself even though she had on a shirt and underwear at least…

“Sorry Unnie, did I scare you?” Her tone was soft, still a little groggy from sleeping. Her black long hair all a mess. She too had on a similar outfit to her sister's small shirt… bunny underwear… Jiwon had long learned not to stare at Wonyoung’s lower half.

“Pfft…? Me? A little. Knock first if you hear water at least?” She suggested with a shrug, and a dumb smile that perfectly showed off her dimple. Which in return made Wonyoung laugh, maybe a little too hard…

“Oh, you’re about to shower? Maybe we should just get in the bath, y’know to save… water.”

Jiwon turned her head slightly, “You mean we as in me and you… should get in the bath?”

“I mean— yeah… Like we used to when we were kids.”

“Since when have you cared about saving water?”

Her younger sister shrugged. Though she looked like she really wanted to do it. Given she didn’t have much physical interaction with her sister over the time she was gone… She knew she had missed that time together. Jiwon let out a sigh, she had to say it.

“Okay, okay… Just let’s do it. But I want the side against the wall.”

“Deal!” Wonyoung jumped in excitement, throwing her towel to the side and running the water herself. It was cute to see her so agile and ready for this, despite being 18 she really hasn’t changed much or at all. She still makes sure to put bubbles in the bath, which is endearing.

Once the water was full they made sure not to look at each other get undressed. In hindsight it didn’t matter, they’d have to see each other anyway. Wonyoung was the first in back faced towards the spout. It was semi uncomfortable, and you had to bend your back a certain way. Jiwon never got to call dibs before, she hated the spout because of that.

The elder sister followed shortly after, curled herself into a ball the other did the same. The limited space between them was endearing. The water was hot, nice to stay in and smelled amazing. Wonyoung flung water at her sister, and of course the other responded with some as well. It all seemed too familiar for both of them.

After they got done splashing each other, there was silence. Jiwon kept her focus on her sister, she felt off staring at her now… She admired her naked body as if she was a muse… She had grown skinny, and so beautiful. She really took care of herself.

Jiwon turned herself around, she completely broke the personal space. Her back laid against Wonyoung’s belly. She guided her hands to be laid over her chest. Laid her head against the others chest.

Wonyoung’s breaths picked up was this the sudden confession she was hoping for? In doing so her erection rose… How she hoped she wouldn’t be able to feel it, though she couldn’t help it. She made faces as if she was in pain… She didn’t want to get caught now. But they hadn’t been this close voluntarily in a while.

“I’m… glad to be home. I haven’t talked to our parents yet but, I really missed times like these with you.”

The small movements of the water as she tried to express her feelings. Despite laying her head between the others breasts she remained fairly neutral about it, technically nothing was wrong with this… right?

Wonyoung cleared her throat, “Y—Yeah… I did too Unnie, I needed you… back so bad.”

“That’s a bit…” Weird to say it like that? Is what she wanted to say but, she didn’t wanna spoil it. It got quiet again, the smooth sound of the water as if they were at an ocean, the only two there. It felt oddly romantic, platonically of course.

Wonyoung couldn’t avoid touching the other, her hands felt lifeless just hanging above her sister's chest. She desperately tried to get a feel of the other, touch anything on her body. She had an idea, rubbing their bodies together. Building a small set of friction, especially for her dick rubbing against Jiwon’s back.

The water began sounding more brash, violent as if the waves were becoming huge. It ruined the serene moment that Jiwon had built in her head. Wonyoung on the other hand… her breaths down her neck and the constant adjustments of her sister began to give her a sense of paranoia.

“Are you okay? Am I too close?”

“No!— No… Sorry sorry.” Her movements came to a complete halt. She eventually returned to her resting position… She needed a way to alleviate herself, she couldn’t hold it in anymore. Her hand dragged to her cock, slowly wrapping her warm hand around it. She couldn’t help but stroke behind her… The other hand trying to casually grab on to her tit…

She was such a degenerate, can’t even stay near her sister long enough without wanting to jerk off to her. She didn’t care anymore… Jiwon refused to focus on the constant moving on the water, or the way it picked up and slowed down even the weird hand positioning. She tried to enjoy the moment, yet each ticking moment she felt more curious.

Her hand reached around, and found itself feeling at her lower back when she found Wonyoung’s hand teasing her own length. Quickly Jiwon’s hand jumped away and she quickly followed standing up from the bath tearing herself away from her sisters grip.

“Wh—What are you doing?!” Her voice was raised, Wonyoung perked up at it, rushing to stand up in the bath. Yet she couldn’t find the words, her dick still remained erect even while getting yelled at.

In response to that, Jiwon blocked it from her vision, turning away, grabbing her towel and rushing out of the bathroom, leaving a trail of water in her path. Slamming the door behind her, as if she couldn’t be anymore dramatic about this already horrible situation.

Jiwon closed her room door behind her, locking it while she was at it. Her head had begun pounding and the melody of her heart was thrown completely off balance. She quickly dried her hair then followed with her body. She needed to take her mind off of it.

Confusion washed over her, she laid naked on the side of her bed. Constantly the feeling of grabbing hold of her younger sister's dick washed over her mind. The image of her erection of such length on her petite body… She hated how she didn’t despise this image that built itself in her mind.

Her and Wonyoung had always been close with one another, each of them had seen parts the other had never seen. Wonyoung always stayed attached to her hip, asking her older sister for guidance… She could never forsake her, maybe she just couldn’t help it… But it was wrong. They were sisters, and sisters don’t do this kind of thing.

But for some reason, she couldn’t find it in her heart to blame her sister. She couldn’t blame herself for letting it happen… As more and more images hit her, that curiosity continued. Hand trailed against her naked body, finding its way towards her slit.

Thumb pressed against her clit, rubbing it around in circles, steaming breaths passed through. She wasn’t even sure how it happened, the more the images of Wonyoung’s cock clouded her brain the hornier she got. All of this felt so good yet half of her felt so bad… Closing her eyes she took in every second of this moment.

This was a fleeting feeling, touching herself to the brief memory of her sister's naked body. With a knock at her door she dropped everything she was doing. Quickly tried to throw pajama pants on a search for a top.

“Coming! Give me a minute.” She squeaked out putting on a white tank top, which squeezed all the right parts of her body, and showed off how hard her nipples were. Unlocking the door, she gave the knob a twist. Of course it was neither of her parents… Who seemed to be completely missing this early in the morning.

It was her younger sister, giving her the worst set of puppy dog eyes she’d ever seen. It hasn’t even been that long has it? Jiwon ushered her in, closing the door behind the two of them. They both sat on the edge of the bed, neither of them facing each other. Wonyoung eventually broke the silence between the siblings.

“I know you’re mad at me, and I was wrong okay… At the end of the day we’re sisters, we can't do that kind of stuff…” She fiddled her hands together, as she stared down at her legs hanging off the bed. More mutual silence.

Jiwon as mentioned didn’t resent her for it, instead she wanted to find another way to give her what she wanted. As she has done her whole life for Wonyoung, making sure everything went her way.

“It’s fine… It happens and I—I don’t think there’s anything wrong with it… Well— it’s a little weird but…” She stumbled on every word she could’ve, trying to find the perfect way to word it. Of course there was no perfect way to make a scenario like this okay morally… But this was their burden.

“Unnie… You’re not upset with me?” Wonyoung immediately turned to face her, eyes widened at the thought… She figured she’d damaged their relationship forever, which now meant she was getting even closer to what she had been wanting. Her elder sister shook her head, placing her hand on the younger sister’s thigh.

For a split second they both open their mouths as if to ask the other a question, but nothing comes out. Wonyoung’s stomach felt so uneasy at this moment, yet was cured when she closed the space between them and went in to kiss Jiwon. Jiwon, originally taken back, resists the first time before returning it.

Leading into the youngest pushing her over onto the bed and mounting her, stacked atop of her as their lips locked with each other. Hands placed themself on her sister’s ass. Giving it a firm squeeze, as they progressed further in their makeout session. Lips battled each other for dominance, yet Wonyoung’s seemed to be the main force in the battle.

Wonyoung began grinding herself against the other, hips grinding against Jiwon’s thigh gap. The constant sound of lip smacking with a mix of moans between them. The lack of any underwear shared in the cheap fabric of pajama pants they owned. They broke the kiss off to catch their breath.

They both stood up, and quickly took off their clothes.

“Unnie, can you sit down…? I have an idea.” Wonyoung requested of the other to which she obliged. Hanging her lower half off the bed, slim legs on display. Wonyoung dropped down to her knees… Opening the space between her sisters legs. Placing her tongue on her slit, teasing her hymen with the tip of her tongue.

“O—Oh! W—Wonyoung-ah…” Before she had even inserted her tongue, Jiwon had already begun squirming around hopelessly at her sister's tongue. Her tongue continued to move circles around the hymen. Licking away at her slit as if she was cleaning a plate. Inserting her tongue in and out.

Pushing it as deep as she could she wiggled it around inside. Jiwon’s nails dug deep into the covers as she bit down on her lower lip. Legs swung up with each motion of her tongue. Removing her tongue, she mounted Jiwon… Pinned her slim body fully against the bed.

Leaning in, Wonyoung proceeded to leave small kisses against her sister's cheek. Making a trail that leads down to her breasts, placing her lips against the right nipple. While her thumb pushed down and spun on the left as if it was a joystick. Lips sucked in her nipple, as her tongue circled around it.

By accident her dick rubbed against the entrance, sides of it coated within the mess she created with her tongue. Wonyoung gave her breasts a rest, as she aligned her tip with her slit. Flicking it in and out of the entrance, Jiwon gasped for air each time she was teased.

Wonyoung didn’t want to just yet… She wanted to play around with her sister a bit more, see what it took for her to crack. She already looked desperate, her pleading eyes, or the way she frowned when she wasn’t receiving any pleasure. These silent gestures she noticed quickly.

“I missed you so much when you were gone, Jiwon unnie… I thought of you so much…” Before Jiwon could respond she pushed two fingers into her slit… Pushing them in out at a steady pace.

“I—I missed you too… a lot…” She choked out, hands reaching out to the other. Trying to grab ahold of anything she could. It was such a pathetic sight already, to be this needy before her younger sister what a bad role model.

“How bad did you miss your little sister? Enough to cum all over her hand?”

Wonyoung was practically ramming her fingers inside of her by now, pushing the same two as deep as she could. Not breaking any eye contact with her sister as she did so. Watched as she tried to wiggle out of it, freshly cut nails digging into Wonyoung’s wrist as a reaction.

Her breathing picked up, big gasps exited as her entire lower half felt relieved, legs violently shaking as they gushed out fluids all over the bed and onto Wonyoung. The youngest was enjoying every second of this, her delicate smile as if she’d still take care of her eldest.

“Oh… You’re so beautiful, y’know that Unnie?”

Jiwon rolled her eyes, but it did get a smile out of her. They always complimented each other, but now it felt a lot more intimate rather than platonic… She was still unsure if she liked that feeling or if she detested it. That's an issue for later…

“Wonyoung… hah… We’re done now…?” Her tone of curiosity, but a face that seemed like she wanted to do more. After all she still hasn’t got a taste of what she risked all of this for in the first place.

Wonyoung shook her head, she was far from over. She only got half of what she wanted, crawling into the bed she sat up against the bed frame. Length stood up erect, using her finger to motion her sister to come over. She took a few seconds to recoup and sat in front of her.

“Hmm… I want you on top of me.” Wonyoung suggested, not something the other should get used to… But she wanted to see if those hips still worked after finishing like she did. She enjoyed watching her sister attempt to life herself up to prop herself on dick. Slit hovered perfectly above the tip, extending her hand for her sister to grab hold of.

They held each others hands as the eldest slowly slid herself down on the length. Slit splitting open as she shrieked due to the pain. Leaning her head back, she continued going down on it, tight walls gripped hold of her length that wasn’t built for her sister.

“Unnie… it’s so… tight.” Wonyoung moaned out, her eyes clenched shut as they fought with this puzzle. Squeezing each others hands Jiwon forced her way down to the bottom. Tip pushed its way to her womb, bulging from her stomach. Slowly she lifted herself up and pushed herself back down, bumping against the womb again.

She grew very loud, a little too loud. But she couldn’t help it. Puffing her cheeks to try and contain her noise. While Wonyoung grunted to express the pleasure she was in, pushing the bed frame against the wall.

The trips up became easier as the member became more and more coated, and as her slit adjusted to the stretching it was put through. The motion eventually became fluid as she began bouncing up and down. The sound of Jiwon’s ass slapping against Wonyoung’s thighs chirped throughout the room.

Jiwon leaned in placing her lips on her sisters… Doing anything to minimize the space between them. The kiss was very sloppy, their steamy breath clashing with each other. It breaking every time Jiwon bounced up but they rushed to kiss each other again.

Wonyoung broke off the kiss, a string of saliva broke and hung from her bottom lip. “U-Unnie… I’m…” Jiwon quickly broke free of their hand holding, as well as lifted herself off of Wonyoung’s cock. Rushing to put it in her mouth so she could taste her sister.

A slow sigh passed from Wonyoung as her toes curled and her whole body relaxed… Releasing her fluid within her sister's mouth. She listened just to hear Jiwon swallow it all.

Wonyoung’s dick had gone flaccid and it had freed itself from the other's mouth. They shared a small laugh and out of sync breaths. It was still early in the morning and they’d have to face the rest of what they did today together… Maybe even make a habit out of it?
