“Onee-san’s lips…they look so soft…”

Waited for K-ON! sub for hours, trolled at /a/. And saw this winrar thread (GO! before 404!)

“Onee-san…”

Staring at her sister’s sleeping face, Ui couldn’t help admire her sister’s innocent looks. Her small but soft lips. Her smooth skin free of any blemish or marks. Her fragrant hair. Her small but cute hands.

Her gaze soon noticed the small mounds on Yui’s chest. Somehow, seeing her sister’s breasts ebb up and down in sync to her breathing made Ui’s face flush red with embarrassment. For a moment, the girl contemplated leaving the room; however to her surprise, she started to feel numb and tingly.

Her hands instinctively, but nervously made it’s way down between her legs where she immediately felt a sticky wetness. Her sister HAS been spending too much time in her new club, and hasn’t been home much. It’s simply not fair!

“Onee-san…you know I love you the most…don’t you…?”

*****

Taking care not to make too much sounds, Ui started to slowly rub her now dripping vagina in careful circles. Each stroke sent a wave of intense pleasure through her slim frame. Her breathing now grew intense as the sight of her sister’s peaceful face only served to ignite her desires even more.

Her sister always used to spend time with her. Mostly because Yui depended on her for a lot of things. Cooking, cleaning, even the occasional homework – there was nothing Ui couldn’t do. And the girl loved doing everything for her sister.

Hearing her sister finally achieve her wish – finding a club where she can belong made Ui feel an unusual feeling of both happiness and betrayal. She wanted Yui to need her forever. She wanted to be everything to her sister. Sure she wants her sister to be happy, but her selfishness made her realize that she wanted Yui to only be happy with HER.

“O…o…onee-san…”

Her fingers pumped in and out of her tight twat; the wet, splashy sounds they produced only heightened Ui’s nervousness and arousal. Her bra has now come off at this point and her free hand proceeded to play with her now exposed bosoms – pinching and twisting at the nipple; the girl making sure her pleasurable moans didn’t rise above a whisper.

“I….I…I’m cumming…”

As if on cue, Yui lazily turned from her bed as she begun to stir awake…

*****

Noticing her sister sprawling awake, Ui panicked as she tried her hardest to stop her hands from fucking her snatch into an orgasm.

But she had come too far to stop now. Her fingers just wouldn’t stop moving. Not even Yui’s puzzled look as she saw her sister masturbating next to her managed to stop Ui from doing the unthinkable.

In a way, she was glad Yui saw this. How long had she been trying to control these urges? The many sleepless nights she spent touching herself while she thought of her beloved sister. In a way, the sight of Yui – puzzled and surprised turned Ui so much that she slid an extra finger inside her vagina as she pumped it faster and faster until…

“I….I’M CUMMING.”

Yui fell on her back as her sister’s sudden outburst caught her off guard. Ui’s legs shook as a gush of warm cum dripped from her quivering legs and onto Yui’s floor.

*****

An awkward silence enveloped the room as both girls finally realized the seriousness of the situation.

“U…um…Ui…? Wha-what’s go-going on…?”

Ui wanted nothing more than to run out of that room now and hide away from her sister forever. But somehow, the realization that she’ll be leaving a puddle of her cum for her sister to clean up made her whole body freeze in fear. Afraid that the sister she loved all her life is now disgusted at her. Afraid that they would no longer be what they once was.

Unknowingly, tears started to flow from Ui’s eyes as Yui jumped up in shock. She never expected to wake up to that sight and now her sister’s crying?

“He-hey! What’s the matter? Stop crying! Um-”

“You…you must think I’m disgusting now right!? You must think…I’m sick…for loving my own sister like this…right? Not only are we both girls…but you’re my own flesh and blood…you must really despise me now right…?”

Now sobbing, Ui tried to bury her tear-stricken face beneath her shaking hands but to her surprise, Yui grabbed her cheeks – as her sister leaned forward to give her a soft kiss in the lips.

*****

“…Onee-san…?”

“Heh heh…uhh…I admit I was really surprised…embarrassed even. But umm…I don’t hate you at all. Umm…I…don’t think you’re doing anything wrong really…but umm…what I’m trying to say is…do-don’t cry! I mean I know this is a shock and all, but please don’t cry!”

Somehow, her sister’s attempt to reassure her fell on deaf ears; as Ui gently touched her lips with her fingertips. Her sister kissed her. That kiss she’s been longing for. The sister she’s loved all her life. They just kissed right now.

“Onee-san…I…I love you Onee-san!!”

“Ui…”

Several thoughts spiraled inside Yui’s head. Just last night she was intoxicated with her desire to learn the guitar. Just last night she was posing in front of the mirror unable to wait for the fun she’ll have the next day with her friends from the Light Music Club. And now…her own sister just confessed to her.

Unable to move, Yui blushed as she noticed her sister’s face edge closer to her’s. At first she hesitated as Ui’s soft lips brushed against her own, but somehow she found it useless to fight as her sister gently grabbed her by the shoulders and passionately kissed her quivering lips.

*****

“Mmpf…U…Ui…ahhh…”

Yui tried her best to separate herself from her sister, but her voice was only engulfed by wetness as Ui slid her small tongue between Yui’s lips. This was her first kiss.

“Ui…my own sister took my first kiss…”

Yui grew lightheaded and submissive as Ui continued with feverishly passionate kiss. Noticing her sister’s slender hands move their way under her shirt, Yui attempted to push the girl away; however, the intense emotion she could feel from her sister’s lips only stopped her.

Her sister loved her THIS much. What right did she have to stop her? It’s not like she hates Ui. She loves her very much. But as a sister. That kiss she gave her earlier, that was just supposed to be a kiss shared between relatives. But maybe Ui understood. It’s not like this adult kiss feels bad…but still…

Yui’s thoughts were suddenly interrupted as she felt wet fingertips squeeze her small breasts.

“Ui…those must be…the fingers…she used to…masturbate…”

Instinctively, Yui began to respond to her sister’s kiss; their tongues wrestling with each other – each one attempting to pin each other down, as their lips continued to be locked in a deep kiss, opening only for a brief moment to breathe.

*****

Somehow, the feeling of Ui’s fingertips slick from her own cum excited Yui. Her nipples instantly hardened as her sister’s small hands carefully pinched them – her palms pushing the mound ever so softly.

Finally Ui’s lips released her from their tantalizing kiss; a thin strand of saliva connected their panting lips from each other. Yui could not find the words to convey how she’s feeling right now. Embarrassed, bewildered, surprised, confused – but most importantly, appalled at the fact that she’s enjoying this!

“Onee-san…look…”

Pulling her skirt up, Ui pointed to her snatch – still wet from her earlier acts of debauchery.

“I just came…but you got me so excited again…”

Yui could not stop looking. Of course she’s seen Ui’s vagina before. They were siblings after all! But just the sight of it in that state – moist, hot, dirty – just the sight of her sister wanting the forbidden made Yui speechless.

“Onee-san…can we do it…?”

Yui could only nod as her sister embraced her from happiness.

*****

“Onee-san…I love you Onee-san…”

“U…Ui…I-I love you too…”

Smiling to herself, Ui slowly stood up and pulled her skirt off – her body no longer feeling any pangs of embarrassment. Yui could only watch as Ui smiled and gently reached over to pick up her brand new guitar; her fingers gently touched the strings as the girl’s quickening breaths turned to sentimental sighs.

“Onee-san…you know I thought you looked really good with this. I…I was jealous. When I saw you sleeping with it…I know it’s stupid. It’s just a guitar! But…we haven’t slept together for so long…”

*****

Turning the guitar over to it’s side, Ui gently allowed the instrument to touch her bare pussy as the girl moaned from the surge of pleasure her body experienced at that instant. Maybe it was the fact that she was fresh from an orgasm and her clit was still sensitive. Maybe it was the fact she was just turned on even a touch could send her body shaking. Or maybe it was the fact that her beloved sister accepted her entirely – her love and her filthy desires. Or maybe it’s just the fact that Yui is noticeably getting aroused at the sight of Ui pleasuring herself with her sister’s beloved guitar.

Slowly gyrating her hips, Ui started to grind along the guitar’s head; her legs grew weak from the wonderful pleasure the instrument gave her body. It took all her strength just to hold the guitar up – and she was worried she might just fall from pleasure any moment now.

To her surprise, Yui’s blushing face looked at her intently. Her eyes didn’t even blink. A soft moan emerged from Yui’s mouth as the girl started to rub her now moist pussy through her shorts.

*****

Somehow seeing her sister touch herself caused Ui to grind on the guitar harder – the girl opting to push the instrument down on the floor for support as she squatted down and pushed her pussy on the guitar’s edge.

Yui, unable to hold it any longer, slid her hand down her shorts and frantically rubbed her clit – the front of garment now soaked with her juices. Unable to hold in her moans, Yui’s panting breath called out her sister’s name as she felt herself nearing orgasm.

“Onee-san…cum…cum…cum with me Onee-san…”

Ui’s hips moved faster as she felt herself near her limit.

*****

“I’M CUMMING!”

Yui’s body shook as her frame was engulfed with the unbearable feeling of pleasure. Her legs instinctively kicked up as more and more of her cum dripped out of her now throbbing vagina.

Seeing her sister finally cum gave Ui the final push she needed to finish – her body leaned back as she gave one final grind on the guitar. Her cum squirted out as Ui’s small body shook with pleasure, drizzling the guitar with her juices.

Falling on her back, Ui felt exhaustion as the pleasure numbed both her body and mind. The guitar fell with a loud PANG, although it was quite clear that none of the girls cared at all.

“U…Ui…”

Using up all her strength to sit up, Ui’s eyes widened in surprise as she saw her sister remove her shorts and panties and sat down in front of her. Spreading her legs, Yui’s fingers shyly touched her pussy’s dripping lips as she spread it open for her sister to see.

“…lick it…please…”

*****

Ui was surprised. Although she wasn’t surprised at her sister’s sudden perverted request. No. Ui was more surprised at how delicious her sister’s vagina looked.

Yui’s pussy was smooth and noticeably tight. The girl’s cum only gave it an arousing look and smell. It was perfect. But to Ui, everything about her sister was perfect.

Ui brought her face closer as she shyly extended her tongue out and gently touched Yui’s clit. The girl moaned from pleasure as Ui was surprised at the reaction she got from just one graze.

Ui brought her hands closer and proceeded to spread her sister’s vagina giving Yui’s hands more freedom.

“Onee-san! I’ll eat you nice and good…so just do anything you want okay?”

*****

Ui started by gently flicking at Yui’s clit with her tongue. Cum started to drip from her sister’s tight twat, causing the girl to feel embarrassed. For almost a moment, Yui felt that what she’s doing with her sister is wrong. For almost a moment she wanted to stop her sister from what ever she’s doing and pretend none of this ever happened. For a moment she started to doubt herself.

But all those doubts ceased to be as Ui started to lap up Yui’s juices, causing the girl to moan out her sister’s name.

“U…Ui…ahhh…ahhh…”

“Onee-san…what do you want me to do…?”

“Sti-stick your…tongue in there…”

Obediently, Ui lapped up the opening of Yui’s vagina before she gently inserted the tip of her tongue inside the pussy. At first the taste felt foreign to her, but it wasn’t long before she found it incredibly arousing.

Pushing it further in, Ui was surprised as Yui suddenly wrapped her thin legs around her sister as she begged her for more.

“Ahhh…yeah…just like that…”

In and out…in and out…in and out. Ui started to tongue-fuck her sister as Yui now removed her shirt and started to play at her bare breasts. The feeling was indescribable. Somehow, the feeling was much better than when she touched herself.

To her surprise, Ui brought her right thumb up and started to gently grind at Yui’s throbbing clit as the girl quickened the pace of her tongue.

“U…Ui…I’m…about to cum…”

*****

The combination of her clit being rubbed and her vagina being licked was too much for Yui.

“I’M CUMMING…!!”

Cum squirted out of Yui’s throbbing slit and onto Ui’s surprised face. Licking at her sister’s vagina to clean it up, Ui embarrassingly stood up as she licked the sides of her lips.

“Onee-san…you’re…incredible…”

Yui’s cum dripped from Ui’s smooth face. Noticing her sister’s dirty face, Yui quickly stood up and apologetically bowed her head.

“I…I’m sorry! I…I’ll get something to wipe you wi-”

Her words were however interrupted by Ui, as she leaned forward and gave her sister another deep kiss.

“Onee-san…I love you so much…I’ll do anything for you…”

“Ui…”

“I…I know…we can’t do it like…boys and girls do but…we can try can’t we…?”

*****

“Ui…”

Yui took one quick look at her sister’s pussy. She was confused. What did she mean, “try”? She remembered seeing some pictures in a magazine she read before about women buying toys that made it look like they had a penis. Does Ui mean that? She certainly did not have those! But if her sister didn’t mean that then what DID she mean?

As if reading her mind, Ui giggled as she gave her sister another kiss.

“If…you trust me…I can show you how it’s done?”

Yui could only nod as she felt hypnotized at the site of her sister finally removing her top garments and lazily letting it drop on the floor behind her. Ui’s tits were surprisingly bigger than her own. The smooth flesh only made the pinkness of her nipples look amazingly beautiful.

Ui licked her fingers for a moment before she gently brought her body over her sister. Slowly letting herself down, Yui was surprised as Ui’s nipples touched her own.

Smiling, Ui started to move her body in a front-back motion as her nipples flicked at her sister’s. Feeling sufficiently aroused Ui reached back and gently pulled her sister’s left leg over her right shoulder before kneeling down over Yui’s other leg.

“Are you ready Onee-san…?”

*****

Yui nodded as she closed her eyes in anticipation.

Almost out of instinct, Ui moaned as she slowly brought her pussy closer to her sister’s waiting twat. Both girls moaned as their already wet vagina touched each other in a gentle, but passionate way.

Holding onto her sister’s leg, Ui started to move her butt as she started to grind on her sister’s pussy. Both girls’ cum dripped and splattered with each motion, forming a growing mark on the bed beneath them.

Yui tried her best to control herself. She didn’t want to lose control in front of her sister. But god, it just felt wonderful. When did Ui learn how to do this? Every movement, every moment, every single thing felt incredible. Yui couldn’t help but bring her hand down and rub her clit vigorously as her body surrendered to the pleasure.

Ui also surrendered. Letting go of Yui’s leg, the girl gently got on her side as she continued to push and grind at her sister’s vagina. Seemingly getting the hint, but mostly out of the deep desire to pleasure herself more, Yui also started to move her hips in sync with her sister’s own frantic movements.

*****

To the sisters, everything just felt incredible. The wet sound their pussies made as they touched each other, the soft erotic moans from the girls’ small lips, the feeling of cum dripping down their petite legs – everything only served as fuel to their forbidden pleasure.

“Onee-san…I…I…I’m about to…cum…”

“Me…me too…I’m cumming too…”

The girls’ bodies shook with pleasure as they came together. The cum that gushed out of their touching slits splattered over their legs and onto the bed. Yui’s body stiffened as she moaned from the incredible sensation she felt. Ui’s tongue rolled out of her quivering lips as she savored each and every spasm her body experienced from the incredible orgasm she just experienced.

Those few moments felt forever as the sisters laid there silently to let everything sink in.

Ui was the first to move, as she quietly stood up and laid next to her sister.

“Onee-san…I…love you Onee-san…”

Yui looked at her sister for a moment before she smiled and reached over to touch Ui’s hand.

“I love you too Ui…”

The girls kissed for a moment before they laughed at how serious each other looked at that moment.

“Oh yeah Onee-san! I forgot to tell you…breakfast is ready…”

Thank you anon.
