"Goodbye mom! Goodbye dad! Have fun on the honeymoon!" Tsukasa waved goodbye with a shining smile on his face as he saw his parents get in the family car and drive off.
Just like that, he was now the man of the house, and it was his duty to take care of his little sister while his parents were away. Little did his parents or anybody else imagine what he had in store for Saki for the next couple of days.
Tsukasa wasn't blind, he'd noticed his sister was finally growing up, and she was growing up into quite the cute girl he couldn't get his eyes off of. And he wasn't going to waste any time now that he has his chance. He locked the main door shut and made his way up stairs to the doorway of his sister's room.
Knock knock knock.
"Sakiiii. Are you awake yet sleepyhead? I wanted to talk with you about something!" Tsukasa said with a singsong tone in his voice.
Saki tossed around in bed a bit at the sound of her older brother’s voice, she was fast asleep until his energetic call woke her up, so it was in a dazed tone that she answered, “Huh? Oh! Yeah, I’m up, give me a second.”
Pulling herself out of bed, she listened to the sounds of the house, but she couldn’t hear her parents. They must have left already.
Opening the door, and rubbing one of her eyes in a still exhausted state, she replies, “Hmm, oniisan, what do you want?”
"Oh! I'm really sorry Saki. I didn't mean to wake you up like that. Thought you'd be awake in bed." Tsukasa excused himself as he stood right on the doorway, looking down at his baby sister.
He towered over her. Not surprising for a young adult compared to a middle schooler, but the size difference was still clear as day. Tsukasa knew that if he wanted to, he could just snatch Saki in a blink of an eye. But he was a better brother than that.
"Aww. You look so cute today in your pyjamas! I could just eat you up, sis!" Tsukasa said without shame as he wrapped his arms around Saki. "I just wanted to ask you if you'd want to sleep together tonight."
“Hmm?” Saki peers up at him, she’s noticed that he’s grown more and more in the last few months, but the height difference never bothered her. He’s her older brother after all, he’d never hurt her. “We haven’t done that in ages, maybe it would be nice again…”
Then she shakes her head, no, she’s a big girl now. She doesn’t need to sleep with Tsukasa just because she gets nervous when their parents are away for too long, “Actually, I think I’ll stay in my own bed…”
"Oh come on, don't say that!" Tsukasa doesn't let her fully finish that last thought before intervening. "It will be fun staying together for the night. We can hug and keep eachother company.”
As if hugging was the only thing he had in mind for tonight. Saki was his little sister. She was only thirteen years old. He knew that none of his thoughts regarding her and his plan were right. But he didn't quite care all that much if he was being honest. He wasn't going to let this opportunity slide.
"I promise I'll make you pancakes for breakfast right now if you say yes." He shamelessly bribed her.
Saki instantly perked up at the mention of pancakes. That was always her weak spot, and her brother was absolutely amazing at making them, “Really?! Heh, well, then yeah! I think that will be fun.”
In a moment of pure joy, she threw her arms around Tsukasa. Due to their size difference, her head only came up to his chest, but she still contently burrowed into him.
“You’re the best older brother ever!” She said with a grin. More than happy.
"And you're the bestest little sister ever!" Tsukasa replied with glee as he wrapped his arms around her in return and held her close to his chest.
He'd make sure that she became the best little sister tonight at least. Saki could probably hear his heart beating loudly just at the thought.
(Later that night).
Tsukasa was waiting in his room for his sister. His pyjama shirt was nowhere to be seen, leaving his lean body free for anyone, for Saki, to see when they came into the room. He only wore a loose pair of black shorts with nothing underneath. It was a good thing the summer heat gave him a perfect excuse.
Saki knocked on his door, she was wearing an oversized t-shirt that covered her shorts underneath. She wasn’t wearing a bra, because what was the point? It was just her, and her brother.
“Oniisan? Can I come in?” She asks, a bit timidly, since it’s been a while since they’ve slept in the same room, but also excited at the same time.
"Of course you can, little dummy." Tsukasa declared as he opened the door wide open, showing himself off to Saki. "Come on in."
Tsukasa practically dragged Saki inside of his room at the same time he closed the door behind her once more. There was no one else in the house. But Tsukasa wanted tonight to feel as intimate and private as possible. He looked his sister up and down, loving her outfit. But he had a lot more fun imagining what was underneath.
"It's a bit hot tonight, isn't it? You can ditch some clothes if you want." He said as he gestured to himself as an example.
Saki flushes red at the suggestion, pulling on the collar of her shirt to hide her face. Of course, Tsukasa being shirtless wasn’t unusual, but she had never been bare in front of him since they were really young.
“I’m…not sure about that, I think that I’m fine…” She mumbles, embarrassed at his words.
Of course, Tsukasa wasn't going to be happy with a no. Not tonight. Perhaps not for the rest of their lives.
"Oh come on. It's not a big deal at all, Saki. I'll tell you what. If you ditch your clothes, I'll ditch the rest of mine. That way we'll both be the same. Nothing to be embarrassed then, right?" Tsukasa sweet-talked his sister.
If anything, his idea just made Saki go redder, till the tips of her ears were scarlet. She still felt hesitant. Extremely hesitant, but Tsukasa was looking at her with such a genuine expression that she didn’t want to turn him down.
She glances down at herself, deciding that she’d be most comfortable with her shorts first. She still has her panties under them, and the shirt is long enough to cover most of it anyways.
She pulls them down to her ankles then steps out of them, then she grabs onto her shirt, deciding whether she really wants to expose herself like that. Tsukasa seemed to think it was a good idea, but she was still unsure.
Tsukasa could barely contain his excitement as he saw Saki's shorts drop to the ground. He could just about make out the lower part of her panties, but that alone was not enough in the slightest for him. He hadn't invited Saki over just to see her cute little underwear. He wanted all of her, down to the last inch of her body. Which is why he didn't wait.
"Come on, Saki. It's really not that big a deal. We're siblings after all." Tsukasa reasoned with her as he himself grabbed the lower hem of her shirt.
Tsukasa lifts Saki's shirt for her, doing so with ease, even if she puts up any resistance against him. And just like that, her small chest was left completely exposed to his hungry eyes. As he took off his own shorts, Saki had a front row seat to see just how hard his brother's dick was at the sight of her body.
"See? That wasn't so bad, was it?"
“Oniisan!” Saki yelps out of shock more than anything else, covering her small breasts with her arms. She didn’t really struggle against his actions, too surprised, but also she knew there was no point. He used to pin her down easily when they were playfighting.
As Tsukasa pulls down his shorts, Saki watches with a naive curiosity. She hasn’t ever seen a penis before, and it was bigger than she expected. She wasn’t an expert about sex, not at all, but she knew what it was supposed to go inside, and she didn’t know how her body would handle something like that.
"Oh come on now. You were going to do so anyway! It just seemed like you needed a helping hand sis." Tsukasa brushed aside her complaint with a smile. "Let's get to bed now."
Tsukasa grabs Saki by her wrists and pulls her hands away from her chest for him to see her small pink nipples. He pulled her along with him as he made his way to bed with her. Soon enough, the pair was softly spooning in the bed. Perhaps it would have been touching and sweet if not for how Saki could definitely feel Tsukasa's large dick pressing against her ass.
"Don't you like being like this again?" He whispered into her ear.
The pressure against her back was making her feel weird in a way that she couldn’t explain, and when Tsukasa pulled her closer, she felt his dick press even further into her body. Involuntary, she let out a whimper at the sensation.
“Oniisan, I d-don’t—“ Saki stutters, unable to push away, her brother’s grip too tight. Her nipples started hardening against her control, and she shifted a bit at the new feeling.
"You say you don't? But you're also telling me you are. Your body isn't lying about how it is feeling about this." Tsukasa kept whispering close to Saki's ear.
He decided to go even further though. He had played safe for long enough. This was all long overdue. His fingers pinched at Saki's hardening nipples, and seeing her body being turned on seemed to turn a switch inside of her brother. Merely holding her and pressing against her wasn't enough anymore. He started rolling his hips back and forth, grinding his cock in between her small ass.
"You are liking this, aren't you, Saki?" He grinned at his question before kissing the back of her neck until he left a red hickey on her pale skin.
She cried out at him pinching her nipples, it was a harsh feeling, but Saki also felt a rush of something down between her legs.
She tried rolling away from him, even if it’s futile, and ignoring the overwhelming sensations that her body was going through, “Oniisan, please—“
"Please what? Do you want me to continue, sis?" Tsukasa mockingly asks.
It barely takes any effort for him to keep her close to him with his arms wrapped around her. She was like a doll in his hands. A cute little plaything he could enjoy to his heart's content with no one home to stop him.
One of his hands decided to go even further, sliding along her stomach and slipping inside her panties. Tsukasa wanted to yell from joy at what he discovered as his fingers traced Saki's virgin slit.
"I bet you do. You're so wet already and I've barely even touched you. Is your big brother making you feel good?" Tsukasa smiled from ear to ear.
Saki twitched in his arms, does she want him to continue? She didn’t think that she should, but Tsukasa also didn’t seem to be giving her a choice. Her pussy clenched a bit at the thought, but she didn’t understand why.
“Ah—Tsukasa!” She gasped as his fingers slid into her most sensitive parts. Saki thrashed a bit, but he kept her still without any issue.
He’s right. She could feel the wetness between her thighs, not something that was familiar, but also not completely foreign. Did Saki like it? It’s hard to tell, and she whimpers even more in confusion.
Tsukasa was a good and caring brother. So he started molesting his sister as gently as he could. At first he merely slipped a finger inside of her wet insides, digging it inside as far down as it went.
For a while, Tsukasa fingered his baby sister with a single finger, but soon enough he built up the courage to slide a second one inside of her. She felt so unbelievably tight inside of her young pussy. He could only imagine how good she'd feel around his dick.
"Come on. Aren't I making you feel good? I can make you feel even better if you only gave me a chance." Tsukasa urged Saki to be more honest with herself.
Saki starts squirming uncontrollably as Tsukasa’s first finger curls up inside her, and when his second one joins it, she can’t help but let out a moan. It felt so tight, like he could tear something if he spread open his fingers, but she couldn’t deny that… something felt pleasurable.
“Oniisan! It feels—weird!” She cries, seeking comfort in her older brother even as he was fully taking advantage of her, and using her body for his own purposes.
"Don't worry, Saki. It's all fine. Just wait for a while and you'll be feeling much better. Let me work my magic and tonight will be a night you'll never forget." Tsukasa said before planting a much softer kiss in Saki's neck. A sharp contrast to how harshly he played with the rest of her body.
Tsukasa wasn't content with just playing like this. Not by a long shot. He sped up his fingers even further, rubbing Saki's wall with every movement he did. But mere cries weren't enough. He wanted to see her cry out tonight. A third finger spread Saki open, and Tsukasa spread his fingers apart.
Saki didn’t know whether to believe her brother or not. She was inexperienced with sex, but it seemed scary, and she was frightened of the responses that her body gave, even as the gentle kiss to her neck calmed some of her nerves. It’s her brother. It’s still Tsukasa. She can trust him. Right?
She lost focus when Tsukasa moved again. Saki grunted at the third digit entering her, squeezing her eyes shut. It’s all becoming too much.
Which means she didn’t notice that he started spreading his fingers until the pressure increased in her pussy to the point that she almost couldn’t take it, “Tsukasa—I can’t—“ Saki’s voice breaks off as she whines.
"Of course you can. Do it for me." Tsukasa growls into her ear as he lets his fingers slide away.
He gets up on his knees beside his sister. If she really did try and make a run for it he knows he could beat her before it was an issue. Tsukasa looms over his baby sister, towering above her completely as yanks down her panties, finally exposing her damp cunt to the hot summer air. His dick lies just a few inches away from her stomach, twitching with excitement at all it dreams to do to her small barely used natural fleshlight.
"Stay still for me." He demands as he pushes two fingers inside. Then he pushes three. Four eventually. And he starts rolling his hand in on itself until his knuckles are inside of her, spreading her walls more than she had ever even dreamed of. His hand slowly pushes its way inside of her, spreading her inch after inch. Tsukasa doesn't stop until he is wrist deep inside Saki.
Saki shivers at Tsukasa’s menacing tone, it’s not something that she’s ever heard from her brother before. It sounds like a threat, and she doesn’t know what he’ll do if she doesn’t listen.
Saki feels him roughly pull down her panties, leaving her completely exposed to him. There’s not any clothing to hide behind now, and it makes the nature of her situation all too real. She stares at his dick, the length so much more than she can take, and gulps loudly.
Saki shuts her eyes again at his words, not even surprised at the feeling of his fingers pushing inside her again, but she still moans against her wishes. However, he doesn’t stop at just two, and there’s a third that enters her. She bites her lip, flinching. Then there’s a fourth and she inhales, trying not to squirm in order to follow her brother’s commands.
But then he keeps going and her eyes fly back open. Tsukasa pushes further and further into her, and she writhes underneath him. It’s too much, it’s more than she ever even imagined taking — his long fingers are curled up into a fist inside her, and he’s shoved up to his wrist within her tight little pussy.
“Oniisan, it’s—” There are some tears that slide down Saki’s face at the overwhelming pressure, “It’s too much!”
Tsukasa takes a moment to appreciate the sight in front of him. Was there any clearer sign of his control over his sister than seeing his hand practically hilted inside of his sister's so far virgin sex?
He could feel his entire hand being drenched in her juices. If he pulled out right now would his hand be made a complete mess he'd need to lick clean? He was certain of it. Saki's body was like a toy to him right now. Even her petite stomach had a small bulge that showed him how deep he was. He could go deeper.
"You did great, Saki. But it's not enough just yet. I'm going to properly spread you now." Tsukasa threatened with delight.
Even if it felt impossible. Even if the movement made Saki feel as though she was going to split in two. Tsukasa kept pushing his hand even deeper inside Saki, no matter her tears or screams. His hand kept crawling forward her underaged insides until he literally couldn't go any deeper. Saki could feel her brother's knuckles press against her cervix.
But soon enough it seemed like relief was coming. Tsukasa pulled back his hand to his wrist again... only to thrust his hand into Saki's depths again. Over. And over. And over again. Tsukasa was practically fucking Saki's pussy with about a fourth of his entire arm.
Saki couldn’t control herself now, she was screaming at the pressure, it was so, so overwhelming. Tsukasa’s whole hand was thrust inside of her, then pulled out, only to be pushed inside again and again. No matter how much resistance her walls gave his hand, he kept breaking through it. Tsukasa paid no mind to her whimpers or pleas to stop, it was just music to his ears. She was something for him to use as a sex toy, and he’d break her until she learns to love that.
After all, his fist was just the first of what would enter her. He’d loved to see her stretched around his cock, as he hammered into her, and he would love to fill her to the brim with his cum. Maybe he could even find some objects around his room to stick inside of her. She’s just a toy for him after all.
Saki’s starting to realise that — that there’s no way out no matter how much she thrashes or cries, and it doesn’t matter whether her body can handle whatever her big brother wants to do to her, because he will make her undergo it anyways. If it won’t fit, then he’ll make it fit.
It’s too much for a thirteen year old to handle, and it makes her start whining loudly once again, everything so unbearable for her young body.
Tsukasa was sure of it beyond a shadow of a doubt, he had the best little sister he could have ever asked for. Saki was so well behaved, having not even tried to throw a single slap at him since he had started violating her body.
Even as he put an entire fist inside of her, she might thrash and turn, but she didn't raise a finger against him, or try and close her legs to stop him. No, she just took it. Even if she was a virgin. Even if she was too young to be doing these sorts of things, she didn't truly fight back against him stretching her out entirely. He loved how obedient it seemed like poor little Saki was.
"You're being such a good girl for me, Saki. You're being a perfect little sister." Tsukasa growled at her before stopping his fist inside of her. "I think you deserve a small reward for being so obedient. Keep being a good piece of rape bait for me and you'll get more."
Tsukasa's free hand pushed against the top of the bulge in Saki's slower stomach. He pressed his palm against it, making her tighten even more against his hand inside of her. His touch slowly went down her stomach, inching ever closer to her forced open pussy. As Tsukasa's fingers reached his forearm just outside of his sister, he began circling her small throbbing clit right above her entrance. At first, he started gentle. It was as if he was granting her a small pause of pure pleasure. But that didn't last long.
Slap.
Tsukasa's palm slapped Saki's clit before going back to the slow circling. This time, the second slap came much faster.
Slap.
The cycle repeated over and over as Tsukasa delivered his harsh love unto his perfect little sister. All the while he kept her pussy nice and full, of course.
Saki whimpered at Tsukasa’s words. There was fear regarding her situation, yes, but his praise also made something deep inside of her churn with pride.
The conflicting emotions were almost enough to distract her from her brother’s fist still being fully lodged inside of her.
At least, until Tsukasa pushed down on her stomach, crushing her insides against his hand. Saki couldn’t help but moan, so overstimulated by the fullness. She didn’t know that a person could feel this stuffed, like there’s no air anywhere inside her pussy. Just Tsukasa.
As her brother moved his hand to her clit, she shuddered in his hold at the immense pleasure that the rubbing gave her. She never experienced anything like this before. “T-tsukasa, what are you—“
Then he slapped her most sensitive part, and Saki gasped, unable to stop the instinct of getting away from the flash of pain, but her brother held tight. The sting mixed with the pleasure whenever he started circling her clit again, and Saki began crying out of pure confusion about what she was feeling.
"Isn't it obvious what I want to do? I want to see how my cute little toy sounds when she is about to cum." Tsukasa stated without the slightest bit of restraint in his voice. But had there ever been any to begin with? "I want to see what sort of lewd faces you can do."
It was obvious that Tsukasa was enjoying the bare show laid in front of him. His eyes were practically devouring every single exposed corner of Saki's lithe body as he bit down on his lower lip in delight. And that was without talking about the way his lower half was reacting.
Tsukasa was rock hard even without a single touch from himself, or from his victim. The mere sight of Saki and the wet feelings of her insides wrapped around his arm was enough to make him seem ready to burst at any moment.
The young adult was even starting to drip a few drops of precum that stained the sheets with his scent. Saki didn't know it, but Tsukasa hadn't cummed at all in the past week. He was more than pent up enough to have fun with her for hours. But he first needed to get her ready.
"Have you ever cummed before, Saki? Know how it feels to have that chill across your spine?" Tsukasa asked with a sadistic smile on his face.
Soon enough his arm was back to pumping in and out of her walls, but this time in much shorter and long strokes, letting her feel the way his knuckles dragged inside her. His other hand meanwhile began speeding up, flicking her clit in a wild frenzy before smacking it. Tsukasa had one goal. Make her lose her mind.
Saki twisted and turned on the bed, but no longer tried to get away. She’s realised that it’s hopeless, but her body is feeling way too much to stay still. She didn’t understand what her brother was saying, choosing instead to clench the sheets between her hands as a way to ground herself.
“N-no. I never…” Saki bit out, barely comprehending the question. She has never even masturbated before — her knowledge of sex being limited to comments made here and there from people older than her.
She tried sticking a finger inside herself once, however it was too tight to be comfortable. But Tsukasa managed to fit his whole hand inside of her, and the feeling of his warm flesh being surrounded by her insides was making her dizzy.
The pressure of her brother’s hard dick pressing against her back didn’t help, especially when he started grinding against her. Tsukasa’s moans mixing with her own in such a natural way.
When he started moving his fist again, Saki yelped at the sensation, burrowing her head into the mattress to try and calm herself from the shivering state of her body.
Tsukasa could tell that Saki was close. She had to be, didn't she? Perhaps all it would take to push her through the edge was just around the corner. He would have loved feeling the way her insides clenched and spasm around his arm while she came.
But he had another idea instead. He hurried his pace for just a couple seconds and then... nothing. Tsukasa didn't just stop, he pulled out his hand from Saki entirely and put his fingers away from her pussy. Only his dick remained pressed against her, as he groaned through his own fun finishing.
"That was fun, wasn't it? You did great, Saki." Tsukasa whispered into her ear before taking a small possessive bite at her neck. He pressed his teeth until he was sure it would bruise. The only comfort he offered was his tongue pressing against it for a moment. "But you want more, don't you?"
Tsukasa shuffled in bed to get lower, low enough to be able to push his hung cock in between his sister's legs and right against her pussy. But he didn't move from there. He merely left his dick laying right above her entrance. It was clear that if she was honest then something other than his hand would be spreading her insides now.
"Be honest with yourself and me. Tell me you want your big brother's cock to fill you." Tsukasa practically roared into his ear as his hand wrapped around her neck. He didn't press hard enough to make her unable to breath, just to make it uncomfortable. If she wanted his dick she'd have to put in the effort to prove it.
A strangled noise came from Saki when Tsukasa suddenly pulled out. The sound was cut off when Tsukasa dug her teeth into her neck, the warm feeling of his tongue kissing away the sharp hurt from the bite. She whispered with glazed over eyes, “I did great?”
Everything felt so empty. She couldn’t stop thinking about Tsukasa’s soft hand being shoved inside of her. It made her cunt tingle in a way that she didn’t recognize, but led to her rubbing her legs together. The touch was too light, not nearly as forceful as Tsukasa. Something was missing — and part of Saki was longing for it.
The moment that Tsukasa lined up his dick with her entrance, Saki’s pulse quickened and she realised that it was the closeness to her brother that her body was desiring. This was wrong. This was so wrong, but she also never felt so much in her life. Plus… Tsukasa means everything to her. He’d only want what’s best for her, right?
Tsukasa’s hand wrapping around her throat was the last straw. Instinct, that weird thudding between her legs, and her wish to please her brother all said the same thing.
Turning her dishevelled face towards him, she started begging, “Please, oniisan, take me. I need you. I need you inside of me. I can’t — it’s so empty now. I need you to take that away. I-I need your dick inside of me, please!”
Saki's words were music to Tsukasa's ears. It's what any brother grooming their little sister could ever hope to listen from their victim's own volition. Saki had fallen for him. It was time to pull her deep into the chasm and never let go of her from here on out.
Today was the first night of the rest of their lives not as brother and sister, but as owner and fleshlight.
"Oh Saki, that's all you needed to say." Tsukasa softly replied to her, his voice losing most of its aggressive tones as she had submitted to him in such a spectacular way. "You're such a good girl for me. Only for me from now on."
But Tsukasa's kind words didn't translate into kinder actions. He treated Saki's body like a doll for his own use. Pulling her hips back and pushing her shoulders so that she'd arch her back and push her ass against him even more. It was so easy to move her like a toy. The young girl barely weighed anything at all for her adult brother. And that made it all the easier for him to line up her pussy with his hips.
Tsukasa had had enough of just grinding his cock against Saki. He was ready to finally take his sister's virginity in full, to mark her insides deep with his dirty cum. But he was going to enjoy this.
He pressed the tip of his dick against Saki's pussy, and plunged himself balls deep in just a single thrust. He couldn't help but let out a deep moan at the feeling of his sister wrapped around his length. His grip on her thighs was relentless, not letting her move an inch and in fact pressing her against him as much as possible. Even after the fisting, Tsukasa could feel just how tight his pretty little sister was. She felt like heaven.
The instant that Tsukasa slammed his cock into Saki’s pussy, she was overcome by the feeling of his hard dick reaching the most sensitive parts of her cunt — the deepest spots that even his fist weren’t able to locate due to the lack of precision. But that wasn’t a problem now, every time that he hammered into her, it was like discovering a new type of pleasure. It was so, so good — to the point that it was burning her up.
Saki’s hand reached out, trying to locate her brother’s, “Oniisan, I need—“ She couldn’t finish her sentence, but she found one of his hands, and he let her take it, though Tsukasa made sure to keep his grip firm on her thighs with his other hand, moving his hips as he thrust into his little sister with as much force as possible.
There was a weird building ache in her lower regions, and it got worse whenever Tsukasa pushed inside her to the base of his cock. Her pussy seemed to clench in rhythm with him, and the tightness of her walls against his warmth made everything even more overwhelming, leading to loud moans from Saki.
Tsukasa had lost all self control. He couldn't focus on anything else besides Saki now. This was what he had been looking for all this time, but now it felt as if he had bitten off more than he could chew. There was a part in Tsukasa, one deep in his mind and his heart that yelled a single loud message to him. He was definitely getting addicted to the way his little sister's wet insides felt as he fucked her.
"Fuuuuuck." Tsukasa moaned into Saki's ear. "I want to plunge inside of you and never pull out."
He had become an animal, that was the only way to put it. The sound of his hips slamming against her small ass filled the room alongside the pair's moans.
Wet skin smacking against each other marked every feral thrust with which Tsukasa hammered Saki's sweetspot. Her body was small and inexperienced, but already he could feel as though she was growing accustomed to his shape.
At first, thrusting inside of Saki was a challenge. But now every thrust made the next one easier. Saki's young body was being stretched out and loosened little by little to become a proper plaything for her older brother. This was the role of every younger sister after all. Siblings were just made to have sex with each other. Least that's what Tsukasa thought as Saki felt tailor made for his cock.
"You feel so good. You're such a good fleshlight." Tsukasa let out between moans as he gripped Saki's hand and buried them in his sheets.
Saki’s body kept getting manhandled by Tsukasa; in the way that his fingers dug into her skin — locking her into place even as his thrusts pushed her back and forth — and even in the way that his other hand interleaved with her’s, pressing his weight into it, so that it dug deep into the mattress.
The worst part was that she liked it. Saki liked being used by her brother, liked being filled to the brim with his dick, and even liked the degrading words that he growled out. She didn’t fully understand what they meant, but they made her pussy tighten against her will.
She arched her back into him, whimpering all the while. Her insides felt sore and tender, abused by Tsukasa’s actions, but the thought of being empty pained her much more. This was her brother’s love. She shouldn’t reject it.
“I’m good, right?” Saki whined, closing her eyes, and giving Tsukasa’s hand a squeeze, “I’m a good little sister for you?”
"Good? Good? You're doing amazing Saki. You're the best little sister I could have asked for. Your big brother loves you." Tsukasa declared without the slightest bit of shame, almost shouting it as if he wanted to say it with pride.
They were siblings. Tsukasa was Saki's big brother. He was meant to look after her, protect her from the harsh realities of the world until she could handle them, and guide her into becoming a better person.
Usually, one didn't think of older brothers manhandling their sister in bed and making her moan out like a complete slut for their dick. But the way Saki's voice flooded his ears didn't let him think straight. Not that he had ever had many qualms with having sex with her since she started to grow into a cute teen.
Tsukasa was a jealous brother. He had front row seats to see how Saki was growing up beautifully. And he was determined to monopolise his cute little Saki and her body.
He would never let another guy even get close to her. She was his and only his. No one else would get to enjoy her body like he did. From now on he was going to selfishly pile drive his own blood as many times per day as it was possible. And he wanted to make it clear in a... special way.
"Saki. Please. Can I cum inside your pussy? Please let me fill your womb with my seed." Tsukasa pleaded with his voice at the same time his body demanded Saki give in. His gripping hand went to the young girl's ass and began groping her ass to his heart's content as if it was a mere object he owned. Tsukasa had asked... but he'd obviously not take a no.
Saki froze at the question, she never considered something like that before. It was — that was wrong. Even worse than anything that they’ve done so far, but…
She wanted to be a good little sister to Tsukasa, and this seemed important to him. That’s not to mention… being filled with his cum would be the opposite of that empty feeling that she suffered through earlier.
Saki shuddered at the memory of Tsukasa completely leaving her body, though the twitching of his dick within her cunt helped her remember that wasn’t currently the case. Tsukasa squeezing her ass resulted in her flinching a bit, but she settled down quickly, getting more used to the rough handling from her older brother.
Finally, though hesitant, she spoke, “If… that’s what you want, oniisan.”
Tsukasa wondered how much Saki even knew about sex. Was she aware of the possible risks of what he had just proposed? She was just thirteen after all, still so young and innocent, part of why he enjoyed taking it all away. It's not like that would have changed his thoughts though. Risk or no risk he was going to creampie her and fill her little cunt to the brim with his pent up balls.
Tsukasa took Saki's go ahead as a sign that he could really do whatever he wanted. If he could cum inside of his own thirteen year old sister then what was stopping him from doing even more? His hips started rolling after each time he buried it inside of her, threatening her every time with ropes of his cum, only for nothing to come out for a while. Tsukasa didn't want to waste this moment after all, he was going to enjoy this underaged family fleshlight for as long as possible.
Saki would have felt Tsukasa's hand disappear from her butt for just a second before feeling a strong sting spread across her pale skin now turned red handprint. It seemed like in between every thrust, Tsukasa was spanking his little sister and groping her ass with glee. He loved the way it bounced. He loved the way her pussy felt. He adored her cute sounds and loving faces. He wanted her forever. But for now he'd be happy with marking her as his.
"I'm cumming! I'm cumming inside you!" Tsukasa roared.
Rope after rope of his hot and sticky seed shot straight inside of Saki's deepest parts. He let out enough to make her womb feel boiling from his milk's warmth. His cum painted his sister's walls entirely white, filling in whatever space his cock hadn't already. And his cock wouldn't move, remaining buried inside of Saki. He wanted to keep his cum inside of her and his cock surrounded by her little pussy.
Only thirteen years old, Saki didn’t have a good grasp on intimate activities like this. She just knew that she had to rely on her older brother. If he told her that she was a fleshlight, then she must be one, right? And if he wanted to unload all of his cum into her pussy, then it must be a good idea.
Her ass shakes from the force behind Tsukasa’s blows, the stinging making her squirm in her brother’s embrace. Once again, the instinct to get away from the pain wins, but Tsukasa wraps an arm around her abdomen which keeps her in place. Despite being trapped, it’s the fact that he let go of her hand in the process that makes her uneasy.
Tsukasa laughs in her ear, low and happy, and she suddenly feels a sticky and warm fluid fill her pussy. Saki moans, her face sweaty, and panting hard. Her insides feel like they are on fire, and she can feel his cum move around in her cunt. Looking down at herself, Saki notices that the white liquid is spilling out of her hole. Something that made Tsukasa let out a displeased noise, and as a result, Saki also felt sad at the sight. She didn’t want to disappoint her brother.
Still, she doesn’t know how she would fit anymore of his cum within her — between his cock and the milky fluid, she felt stretched to her limits.
In a breathy tone, Saki turns her head a bit, trying to meet her older brother’s eyes, “Oniisan, are we… done?”
The rush should be over. The adrenaline pumping through Tsukasa's brain should have begun dying down now. But he didn't feel like that in the slightest. His mind was still focused on the beautiful girl he had right in front of him. Saki's question made Tsukasa chuckle. He pulled her head back with a hand to her chin and pressed his lips against her, giving her what he believed had to be her first kiss. A bit of an odd order for all this to happen.
"Done? Oh Saki. Not yet. You have to help me clean up now." Tsukasa explained with a soft and kind grin, a kind Saki was far more familiar than those from the past while.
Tsukasa reached out to grab Saki's panties he had discarded before and used it to clean up the cum that spilled out of her sister's hole. As hot as it was to see it outside as proof of him claiming her, its place was inside his plaything. Tsukasa pulled out slowly and delicately, pushing his sister's panties against the place where his dick met her entrance. As soon as his dick was outside of her once more, he shoved her panties inside her pussy, filling her once more and hopefully plugging most of his cum inside of her.
The older brother carried his sister in his arms and set her down on her knees in front of the bed. He sat down at the very edge with his legs wide open for her to be in between. In front of her was both of their work, Tsukasa's half hard cock completely covered in cum and her own juices. Her brother was gripping her from her golden locks to have her look up at his face.
"Now, you have to clean me up. And the best way to do that is to swallow all this mess you made me do." Tsukasa explained to her.
Saki shifted on her knees, and in the process, she could feel the panties that were stuffed inside of her pussy brush against the tender parts of her cunt. She grunted at the sensation, before comprehending Tsukasa’s words.
“Swallow?” Saki questioned, confused and nervous. She didn’t know that was something that people did — but if it would make her big brother happy, then she could try it. Staring at his large cock, Saki gulped; unsure how it fit inside of her previously, and even more unsure about how she’s going to fit her mouth around it.
Tsukasa’s hands were in her hair though, pinning her head in between them. Their presence was a reminder that she has a responsibility. Nervous, but willing, Saki leans forward and opens her mouth, letting Tsukasa’s dick be swallowed by her lips.
The taste was strong — Saki didn’t know if she liked it, but it was addicting anyways. She had to properly clean up her brother, otherwise he would be upset, and she didn’t want him to be upset. It’s enough for her to go further and further, licking up his cum and her wetness, which makes Tsukasa moan in delight at his baby sister submissively swallowing his cock.
Eventually, she goes too far, and she starts gagging. Saki tries pulling back, but Tsukasa tightens his grip with a menacing grin, not letting her move a single inch.
Tsukasa thought that perhaps he'd need to be more convincing with Saki. He doubted she knew the first thing about a blowjob. Instead, he was surprised by how eager Saki seemed to prove herself as a good little preteen slut. She had just been creampied not five minutes ago and already she was eagerly going down on his dick. Tsukasa had her wrapped around his finger even more than what he'd thought before.
"God! Just like that Saki!" Tsukasa lets out as he throws his head back from the sheer pleasure he lives through. Everytime Saki reached a soft spot of him, she'd know it by how his hands gripped tighter on her hair. God, if Saki wore ponytails to bed, Tsukasa would be using them as love handles. "Keep going, baby. I know you can reach the base. Do it for your brother."
Every drop of cum that Saki expertly cleans is matched by another one dripping around her lips and her chin. Tsukasa has the privilege of seeing as his cum drips down his sister's face and makes a mess of her small developing chest. It was barely not flat, but that was enough for Tsukasa to enjoy.
But one thing he wouldn't enjoy was his little baby not letting him hear how she gagged. So he kept her head down, not pushing her further, but keeping her far down him so that she felt the tip of his cock go from his mouth down into her throat. Tsukasa loved how her throat spasmed with him, after all.
"Good girl." Tsukasa said as he finally pulled Saki up for some air. But if she expected respite she was wrong. Soon enough her big and strong brother pulled her mouth down her dick to the same height as before. "Let's keep training your gag reflex."
Saki didn’t know what a gag reflex was — all she knew was that her throat was rebelling against her actions, making her cough and choke on her brother’s cock. Without even noticing it, Saki’s eyes began tearing up, and soon there were tears leaking down her face as she struggled to breath around Tsukasa’s dick.
Tsukasa looked like he was enjoying her involuntary jerks, as her throat constricted against her dick. He held her down, forcing her to stay still with his dick two thirds into her mouth until her vision started to blur.
It’s like he knew exactly when to let her up for a brief inhale of air. Tsukasa quickly learned her limits, and exactly how far he could push them to avoid her passing out, and he exploited that to his advantage. Each time, Saki is pushed a bit and a bit further down his length, inching towards his base.
Trying to centre her breathing, Saki moves around her tongue, swirling it against Tsukasa’s dick in the process. The action makes him shift around, groaning, and it causes Saki to start gagging again, but that just pleases Tsukasa more.
Eventually, during one of the brief breaks that he allows her, Saki looks up at him with shining tearful eyes, “Oniisan, I can’t take it any further. It hurts.”
Tsukasa can't help but throb inside of his little sister's throat. He can't help but love every small detail from tonight. From the feeling of his sister's tongue swirling around his girth. To the warmth of her throat. Or even the way that he could see a bulge go up and down Saki's throat whenever she swallowed him. He turned to the side, looking at his full body mirror on one end of the room. It was oh so wrong, but being able to see Saki kneeled in front of him in that mirror was something else. He could only imagine it as the image someone would see if they walked in on them, of a small girl choking on her big brother's cock for the first of many times. Which only made her pause all the more disappointing.
"Oh Saki. Please, can't you try some more? Just for me. Please, I promise I'll push you down less this time. I'll count up to five this time. That's all you have to do for me. Look at me in the eyes while we do so." Tsukasa explained to his sister before he pushed her down his length one more time.
Tsukasa pushed his cock down his baby sister's throat once more, and looked her straight in the eyes as he did so. The sight of Saki's lips wrapped around his dick was incredible. And of course it was becoming harder for the girl, Tsukasa was once more fully hard thanks to her wonderful work on his dirty flesh.
But in truth, what Tsukasa liked the most... was the look Saki gave when she was just about to pass out. Something about that mere thought did something to his brain. His little sister passing out from his dick... a tempting idea, and one with which he would flirt just a little bit.
"One..." Tsukasa began as he made Saki reach her new record. But something was odd. He didn't count to two instantly. Poor girl. She trusted her brother too much.
[Two]
[Three]
[Four] "Two..." Tsukasa was taking his sweet time with his counting, enjoying the way that Saki gagged and choked on his dick all the while.
[Five]
[Six]
[Seven] "Three..." Could you blame him? He had spent so long waiting for this moment. Why not enjoy it?
[Eight]
[Nine]
[Ten] "Four..." Tsukasa loved the face Saki was doing. He adored the sight of his little sister struggling to breath as he held her face down on his dick.
[Eleven]
[Twelve]
[Thirteen] "Five!" Tsukasa declared with pride for his little sister doing so well as a fleshlight. He finally pulled her head up, freeing her to breathe again.
Saki’s vision started to blur about halfway through her brother’s countdown. There were black spots giving her tunnel vision, only allowing her to see Tsukasa’s face looming above her. The cock in her mouth was back to being solid, constricting her breathing to the point that she was feeling faint.
Whenever she inhaled, her throat tightened around the dick stuck inside of it. Something that made Tsukasa shudder in delight, and resulted in his cock twitching in a way that just repeated the cycle. She was sore, and scared, but even Saki’s gulping and gagging seemed to please Tsukasa.
Tears running down her face freely at this point, Saki completely believed that she was going to pass out; her head began feeling light, but as she closed her eyes — expecting to not open them again — Tsukasa pulled her off of himself, grinning all the while.
Saki uncontrollably sputtered and coughed, saliva and cum running down her chin. After a few moments, she steadied her breathing again, “I… I don’t think that I liked that. I thought that I was going to pass out…"
Saki had nearly passed out. Her face was a mess of tears, saliva, and cum. Tsukasa could not be more turned on by anything in the world, he was sure of that. There was something primal in him that enjoyed seeing Saki in this state. Something that whispered in his ear to ruin her even further. But he was also her loving brother, and the sight tugged at his heart in a way he didn't expect it to,
"Thank you so much for trying so hard for me, my love." Tsukasa declared as he grabbed Saki by her hair, but this time raised her head up towards him. He planted a soft kiss on her forehead, and a second and a third. Saki had more than won her brother's complete adoration. "I loved it. Let's try going all the way to the base now. It will be quick."
Tsukasa's tenderness was over for now, and it was back to his pleasure. Saki wouldn't be able to believe her eyes. His dick's tip was leaking precum again already. Even after cumming what felt like a whole litter inside of her womb, he still seemed to be able to cum. Maybe if she did a good enough job he'd do so.
"Be a good girl for me." Tsukasa ordered as he brought Saki's head down, pushing her with his two hands atop her head. Saki was pushed past his tip. Down his length. And her lips once more began scraping off the cum left over around his dick. She was doing this to clean him after all. Until finally, her nose brushed against his pubes. But she didn't have much time to smell the strong scent of sex imprinted on them before Tsukasa stayed true to his promise this time and pulled her back up.
The sudden presence of her brother’s dick inside her throat again made her gag around him, especially as he went even further than previously, pushing her down to his base. There was an uncomfortable burn as Saki swallowed, but she thought about Tsukasa’s words.
He was so happy when she tried taking his length, and she wanted to see that smile again. No matter how much it hurts. With that, she decided to ignore the discomfort, focusing on sucking his dick.
It was over much quicker than last time. A fact that caused a mix of relief and disappointment to swell inside of Saki. As foreign and nerve-wracking as everything was, she wanted to prove herself to Tsukasa.
Licking the cum off her lips, and making a face at the salty taste, Saki muttered embarrassedly, “Oniisan, I’m sorry that I couldn’t take your dick without gagging.”
She averted her eyes, rubbing the extra filth off her cheeks with one hand, and speaking in an ashamed tone, “It was too big for me…”
Saki might as well have proposed to him right then and there. He could have only dreamt about such statements in his wildest dreams. Saki was apologising for not being able to suck him off well enough. She wanted this. She wanted to be a good little oral toy. Maybe Tsukasa was wrong. He didn't have a little fleshlight, he had three.
"Oh Saki. You have nothing to say sorry for." Tsukasa's hand played with her hair softly as he spoke. "It's your first time trying. You'll get better at this. And one day I'm sure you'll be taking my dick as hard into your mouth as you did with your pussy."
This was incest. Plain and simple. Tsukasa had just had sex with his sibling and then had her suck on his cock. Saki and Tsukasa could never go back to being normal siblings. But that didn't mean he didn't love his little sister. He just loved her much better than how other brothers loved their sisters. If incest was meant to be that bad then why did this feel so good?
"Let's try something else instead." Tsukasa said with a smile.
He helped his sister up back on her feet and dragged her across the room, until they were both right in front of his mirror. He held his little sister in front of him so that she could see the two of them in the mirror. She was completely exposed, bare naked and with his brother in the same way right beside her. Her neck had a couple of hickeys, her hair was a mess, her inner thighs were soaked, her cute face had tear streaks. And Tsukasa was smiling proudly at all of it, his dick rock hard and twitching for more action.
"Be a good girl and bend over for me so that I can fuck my sister's ass." Tsukasa ordered harshly into Saki's ear as his large hands gripped her shoulders.
That was something people did?
Saki watched her reflection pale at the order. She didn’t know much about the details, but she knew that things didn’t go inside there nearly as easily as they went inside your pussy. And considering that Saki felt like she was going to break when Tsukasa entered her cunt, the prospect of him inserting his cock into her little ass terrified her.
“Do we have to?” Saki mumbled, carefully checking out Tsukasa’s expression in the mirror. His hands clenched tighter around her shoulders at the question. A spark of worry shot through her. She didn’t want to make him mad. “It’s just that—I’m scared, oniisan.”
Saki touched her neck out of nerves, wincing when she reached a hickey. It made her glance at her reflection closer. She was covered in white liquid, and Saki could still feel her brother’s cum inside of her. Along with her panties. The reminder made her cunt thud, and she shifted her weight uneasily.
Tsukasa could understand that Saki was scared of having the last of her virgin holes taken from her tonight. But it wasn't like he was going to let his little fleshlight think that she had more control over this whole situation than she really did. No, he was going to get what he wanted.
"It will be... fine!" Tsukasa growled out as he grabbed Saki's locks with a hand.
Tsukasa pushed Saki's face up against the mirror at the same time he kept her hips in place with his harsh grasp. Using her like a sort of mannequin to get the pose he wanted, Tsukasa made his little sister stick out her ass for him himself. She looked so good that he couldn't help but smack his dick against her ass several times, as if he was playing with a toy of his.
"Stay there." Tsukasa ordered with a deep tone.
Tsukasa spread Saki's ass and half swallowed. A second later he let a long string of his drool drop down into her asshole, He rubbed the spit on her ass with one of his thumbs, preparing her for the real deal.
“Hey, stop it!” Saki struggled against the mirror, trying to push herself away from her brother, but he had her totally pinned. Tsukasa was able to force her into the exact position that he wanted, and Saki could barely see what was happening with her face pressed into the wall. She only knew that her ass was in a vulnerable position.
Tsukasa didn’t waste any time in taking advantage of this. Saki whined at him smacking her ass, continuing to squirm, but she panicked completely when she felt him spread her ass apart. There was a wetness that followed there, then she soon felt a tight pressure.
Her brother slowly pushed a finger into her hole, deaf to her shouts. He dug in more and more, and Saki couldn’t take it anymore, rasping out a groan that was half pain and half desperation.
Desperation for what?
She wasn’t quite sure.
Another finger started to work its way inside of Saki, and she started thrashing again in Tsukasa’s grip, grunting at the overstimulation. Her ass felt like it was being torn apart by his fingers, and the movements jostled the panties in her cunt, sloshing around the cum trapped inside of her.
She heard her brother chuckle, “Don’t panic so much about my fingers, Saki. I still have to put my dick inside of you too.”
"Just be a good girl and don't push your luck. I can always treat you far harsher, my cute little fleshlight." Tsukasa ordered.
Smack.
"Am I being clear?" Tsukasa asked, but he didn't really care much for an answer.
He got to work on what he had to do, breaking in her ass the same way he had broken in her tight little pussy. He began finger fucking Saki's ass to his heart's content, pumping in and out of her without mercy. He was pistoning her little asshole without a single care for how hard Saki yelled out in pain or desperation. Whenever he felt like he was being too harsh with his baby sister he just used even more of his spit inside her butt.
"Come on, don't be shy. You know you want me to also fill your ass. Just say it and we can make it true." Tsukasa told her as she let her face get a bit farther away from the mirror so she may see how he was treating her.
Tsukasa was grinding on her without the slightest bit of shame. He was covering her ass in her own spit and precum, leaving Saki an even greater mess than she already was. He wondered if she would be able to stand once he was done abusing his little sister. His parents really should have known better than to expose Saki to being raped like this.
Having given up on trying to get away from her brother’s bruising hold, Saki finally goes pliant against him. Just closing her eyes and attempting to ignore the discomfort. After relaxing her body, Tsukasa’s fingers started hurting a little bit less. If she focused enough, it could maybe even feel pleasurable.
Her heart hurt from Tsukasa’s annoyed tone when he reprimanded her. She didn’t want him to hate her. Saki wanted to be good for him. That’s all she ever wanted to do.
Saki could see the mirror reflecting Tsukasa humping her back while pumping his fingers inside and outside of her ass. The sight itself was intense enough that she had to look away. It didn’t matter anyways, she could still feel his dick grinding against her skin. She could still feel the precum smearing all over her. And of course, she could feel his long fingers clenched between her tightest hole.
Saki didn’t know if she wanted Tsukasa’s dick inside of her ass. She didn’t know if she could take it. But she did know that she wanted him to praise her like he did before.
She wanted to be a good little sister to him.
“Please, Tsukasa, fill me. Use me. Just do anything that will make you proud of me,”
Saki begged hoarsely.
"I know my good little toy will make me so very proud by taking my cock." Tsukasa replied before he turned his sister's face to meet him. He gave Saki her second ever kiss, not caring if he could still taste himself on her lips or no. She ought to be rewarded for answering so well.
Tsukasa spread his two fingers as far apart from each other as he could to make sure to give Saki one last stretch before she got what they had both been waiting for for so long. He pulled out his fingers, but she didn't get a moment of respite before she'd feel the head of his dick press right against her ass.
He pressed the very tip inside of her, slowly spreading her out farther than his fingers ever had. Before Tsukasa had loosened up Saki with his fist. He was now going to do the same with something far dirtier
Tsukasa hammered straight into Saki's ass. He pushed himself as deep as he could, struggling against his sister's tightness in every direction that was seemingly trying to push him out. But, of course, he was going to let something like that happen.
Instead, he pulled his cock ever so slightly out only to then slam back their hips together. Over and over, making sure he would claim Saki's ass as well. He wondered if she would be able to handle being filled a second time with his cum.
Saki screamed when Tsukasa thrust his dick into her tight hole. There was so much resistance that her brother had to break through, and he did it so mercilessly. She has never felt this stretched, like her walls were crushing around Tsukasa, making him part of her body.
He didn’t falter though, diving in and out of her ass. Eventually, he even slipped a hand around her chest, and started groping her breasts. His hand was so big that it completely enveloped her tits.
Between his dick plunged deep into Saki’s ass, his left hand roughly fondling her chest, his right hand keeping her pinned to the mirror, his cum moving around inside her cunt, and even her throat remaining sore from its earlier treatment, there wasn’t a single part of her that Tsukasa didn’t touch.
It was too much. Way too much. Saki was too young to comprehend such strong sensations, it fully overwhelmed her — her eyes glazing over as she completely lost herself.
Saki felt tight. Almost too tight for Tsukasa to enjoy it. He felt like his dick was being milked for all its worth by her, as if her spasming body was trying its best to milk him of another load of hot cum. How could he not be completely in love with her ass? How could he stop his merciless jackhammering of her deepest reaches? It was such a view. One only needed to look at the mirror in front of them.
A single moment said it all. It was a young adult raping a preteen's ass and making her lose her mind. Tsukasa towered around little Saki so much that he needed to bend his knees to get a proper angle with which to fuck her. She might as well be a mere slut doll compared to him. She had no option but to be his.
Saki wasn't strong enough to stop Tsukasa from pinching and twisting Saki's nipples with her left hand. She couldn't stop him shoving three fingers inside her open drooling mouth and digging them in until she was gagging. And she was definitely not strong enough to even complain as Tsukasa dug his teeth into her collarbone, closing his mouth more and more until he could taste iron on his tongue.
Saki coughed when Tsukasa jammed his fingers down her throat, triggering her gag reflex as she sputtered at the intrusion. There was a blossom of pain in her collarbone as Tsukasa marked her with his teeth. Twitching at the sting, Saki choked out a sound — whether it was a complaint or a moan, neither of them could tell.
Tsukasa was tearing her in half, he had to be. There was no way that he could fit his dick inside of her tight little asshole, but he was still managing it. Moving in and out at a brutal pace, and leaving love bites all over her neck.
When he finally removed his fingers, Saki heaved for breath in relief, but it wasn’t long before he leaned next to her ear. Tsukasa softly spoke, “If you want to be a good girl, I can help you feel great again.”
Saki’s knees went weak when he placed his hand over her clit, ever so gently touching it. Trying to catch his eyes in the mirror, she muttered, “Oniisan?”
Tsukasa didn't just want to use Saki like a sex toy, he needed her hooked on being his sex toy. He wanted her ready everyday to give him her body whenever he commanded. And so he couldn't focus just on his fun while fucking her. He needed her to be just as driven by pleasure as he was.
"Try and stand straight, sis. I know you can." Tsukasa whispered as he looked her straight in the eyes through the mirror. She had a perfect view of how his gaze was like that of a predator ready to eat his prey.
And he wasn't going to just eat her, he was going to devour her. He kept his eyes on hers through the mirror as he began softly flicking her clit all the while he kept destroying her body from behind. Saki was surrounded from the front and behind, her pussy tingling with pleasure from feeling full with her brother's cum and his fingers pleasuring her clit softly and lovlingly, all the while her ass was growing sore and slightly painful from Tsukasa's cock not slowing down in the slightest. The way her face contorted between both feelings only made it all that much better for him and let him know what to do. When it seemed like the pain was too much, Tsukasa would kiss Saki's neck or face in the most loving way.
"You're such a good girl." "A perfect girl." "A perfect cumdump." He cheered her on with these phrases over and over again, as if trying to program her mind when it was at her weakest.
Despite Tsukasa’s belief, Saki was convinced that she would fall over if she wasn’t shoved so forcibly against the mirror with Tsukasa’s weight pushing into her. Quite literally, as his cock didn’t halt for a single moment. Treating the friction in her ass like a challenge, he was dragging her over her limits.
His fingertips rubbing her clit was bringing her such pleasure that it almost distracted her from the discomfort of everywhere else. In a similar way, his gentle kisses helped clear Saki’s mind, and she associated the words that he was saying with them. Even if she didn’t understand their meaning.
“I wanna be good for you.” Saki cried out, desperate to please her brother. Both for his sake, and her own. Her whole thought process in pieces, she searched for something else tp say. Something that would make him happy. Because her body would always end up feeling better when he was happy.
Her brain came across some words that he said previously, and she echoed them without thinking, “I’m your good little cumdumpster. Your—your perfect slut.”
Tsukasa couldn't help but feel like a chill went down his entire length when Saki said those words. Never would he have imagined that she was this far gone already. He had planned to break her in throughout the entir week they had to be alone. And yet already it seemed like her poor naive mind was already breaking under the pressure she felt in her ass. But perhaps she was breaking too much.
Saki seemed like she was about to fall down any moment now. But that was fine by him. He didn't need her to use her legs. He'd use them instead. In an instant, Tsukasa grabbed Saki by her thighs, and lifted her legs off of the ground. Her legs were spread wide open as Tsukasa carried her, exposing her perfectly to the mirror. The poor girl needed to wrap a hand behind his neck to keep her balance.
"Then be a good girl and put on a show for me with your free hand while I claim you." Tsukasa asked her before he gave her a small kiss on her lips.
That was the last bit of comfort Saki received before she felt her entire body being yanked down onto Tsukasa's dick. A moment later she was being raised until only the tip remained inside. Over and over, Tsukasa played with Saki like she was a fleshlight, moving her entire body to masturbate with her.
Saki was like a limp doll for her brother to manhandle into his preferred position. Only half his size, she was lifted into the air with any issue. The lack of solid ground under her feet made Saki even more disoriented, relying on her brother to keep her steady. Completely depending on him, even as he’s using her like a sex toy. She couldn’t help but groan at being forced down his length without any respite.
Put on a show?
The demand confused Saki, unsure about what to do. She tried to think about what Tsukasa liked. He seemed to enjoy her little breasts, so she brought her hand to one of them, surprising even herself with how hard she twisted and squeezed it. Unable to prevent herself from whimpering, she continued groping herself for a bit.
Eventually, she tried a new tactic, reaching her hand down into her pussy. Inserting two fingers, Saki flinched when she hit the panties stuffed inside of her, but brushed past them, focusing on the way that the cum inside of her sloshed around her fingers. She curled them, aiming for the same spots that Tsuksasa reached, and yelped when she pressed against one of them.
This continued for a while — Saki sliding her fingers in and out of herself in tandem with her brother violating her ass. Both actions moved around all of Tsukasa’s cum that was still plugged in her cunt.
When her pussy got too sensitive, she removed her fingers. In one last move micking her brother, she slipped her digits inside of her mouth, licking off the mixture of herself and Tsukasa. It was a strange taste, but one that she was getting used to being on her tongue.
Tsukasa could barely believe his eyes. Saki was just thirteen, she was still a naive and innocent girl just an hour ago. And now? Now she was doing her best to satisfy him, using her entire body which she knew he adored to catch his attention. He loved how she did it so well. His balls throbbed wanting to release already. But Tsukasa wanted to enjoy this more, he wanted to use his sister's little ass for his pleasure a lot more.
Tsukasa´s thrust became slower, but that wasn't as freeing for Saki as she might expect. Tsukasa lowered her unto the very hilt of his dick, only for him to keep her there for a couple seconds, relishing in the warmth of her ass. He would take his sweet time enjoying it, grinding their hips together in every small respite before lifting Saki again. It was slowing down the inevitable, but not stopping it.
"Do you like the way my cum tastes, Saki? Well then I'm going to fill your ass with it. Can I? Can I cum deep in your ass?" Tsukasa asked his little sister as he lowered her on his dick one more time. This time he took the opportunity to softly suck on her earlobe before lifting her again.
Saki bit her lip at the question, unsure about how to answer. She could still feel Tsukasa’s cum filling her pussy. It created a warm sensation, as weird as it felt for liquid to be moving inside of her with every thrust from her brother. Not exactly unpleasant, but to be stuffed with his fluid in both her holes?
She wasn’t sure if she could take it, but Tsukasa has already pushed the boundaries of her body several times tonight. If he thought that she could manage it, then he was probably right. It couldn’t be worse than his hard cock being burrowed inside of her ass, and Saki proved that she could handle that, didn’t she? She was handling it so well, even when Tsukasa had to use all his strength to drive past the resistance of her tight little hole.
“Okay, oniisan, you can do it.” Saki spoke softly, staring at herself in the mirror, trapped in her brother’s embrace, hilted on his dick, covered in both their bodily fluids, and about to have even more of Tsukasa’s cum flowing inside of her.
Did it make any difference at all? Tsukasa knew that he was going to empty his seed inside of Saki one way or another. She could have yelled at him and begged him not to do it and he would have done it all the same without a single regret. No, that wasn't why he asked for permission. He did so because it turned him on like crazy to hear her be an obedient little sister and tell him that he was free to cum inside of her.
Somehow, Tsukasa got even harder as he heard Saki's words, growing even thicker inside of her. He felt like he could barely move, but he didn't care anymore. He wanted to make her his and his alone forever. Even with Saki feeling tighther than ever before, Tsuksa pushed through the pressure and began hammering her tight little ass faster than ever before. He was using her as a fleshlight to finally cum, even if he had already done so not that long ago.
"God! Saki! I love you!" Tsukasa yelled out as he pulled Saki down until he was balls deep on her. She might have even been able to feel them throbbing as her beloved brother finally burst again.
It was like an explosion of pleasure for Tsukasa. He'd never cum this much in his life, he was sure of it. He kept shooting more and more of his dirty milk inside of his little sister, pouring so much of himself into her that he could even see Saki's stomach slightly bulging from the amount in both her pussy and her ass. And what a sight his sister was in the mirror. Tsukasa kept his eyes focused, but he was more than happy to see not a single drop of his cum left Saki.
Saki could feel her brother’s cum spilling inside of her ass, not a single speck of it being allowed out. She was scared that she was going to burst, the liquid in her body filling her to the brim, pushing against her insides and even making her stomach bulge from the sheer lack of space for everything.
Her grip around Tsukasa’s neck faltered, and she would have fallen off him if he didn’t notice. Of course, Tsukasa had a keen eye, and made sure to keep his sister pressed tight against him so that not one drop of his cum would be able to leak out of her thirteen year old ass. Just in the same way that his previous load remained deep inside of Saki’s pussy.
Saki closed her eyes, way too overwhelmed. Her pussy was clenched around the panties and the cum from the first creampie, while Tsukasa’s dick was stuffed inside of her other hole, keeping his seed from the second creampie plugged in her ass.
God. God. Tsukasa's heart was pounding on his chest like a drum. Even if Saki was light, fucking her like this proved to be a challenge and a half for him. He'd done his best, and now he was left breathing heavily against her bruised and pretty skin. For a moment he remained just like that, holding Saki in place and appreciating her warmth against his chest. She was his little treasure now. And he couldn't possibly be any happier about it.
"That was... amazing Saki. You did incredible. I've never felt better..." Tsukasa said in between ragged breaths. He swallowed his pride and whispered straight in her ear once more. "I could not be happier that I gave you my first time."
With that embarassing truth out of the way, Tsukasa carried his sister all the way to his bed. He sat at the edge of it, never bothering with pulling out of Saki. Now that he was much freer he put his arms around her full stomach and began peppering her back and neck with small little kisses. Over and over again he gave his little sister as much of his appreciation as he could.
"I really did mean what I said... I love you. I love you more than I love anyone else... I'm sorry I couldn't think of another way to say it to you." Tsukasa admitted as he pressed his cheek against Saki's shoulder.
Saki’s whole body was aching from her brother’s treatment of her. Even when it was pleasurable, she’s so young that such actions were taxing. It led to her being completely docile in her brother’s arms, basking in his affection as confirmation that she did a good job.
“I love you too,” Saki mumbled, only half aware, but meaning the words that she was saying. She stayed still for a few seconds before realising what she wanted; gripping his hand, seeking comfort from her older brother.
“I’m so tired, oniisan,” Saki whined a bit, unsure about how else to express what her body was feeling in the aftermath of such intense activity.
Tsukasa grabbed Saki's hand as if it were the most delicate thing in the world. He rubbed his thumb over it softly, enjoying the small brush of their skin together. Oddly enough, such a small action felt like the most intimate moment of the entire night for Tsukasa. He brought the small delicate hand up to his mouth and planted a soft kiss on his sister's little knuckles.
"I think we're both tired, my love." Tsukasa replied to her. He remembered what had started all of this. "Please stay and sleep with me here."
Tsukasa lay down on his bed, bringing Saki down alongside him. He covered the two of them with the sheet and got comfortable in spooning his little treasure. His two arms were wrapped around Saki. Delicate finger tips ghosted her stomach, softly rubbing her skin, as if tenderly wanting to confirm that, yes, Saki was right beside him.
"I'll always love you." Tsukasa gave one last confession before closing his eyes.
With her big brother draped around her, and both of them buried under the covers, Saki felt more content than she ever had. She started drifting off in his arms, succumbing to the exhaustion that ran throughout her from being used so thoroughly for the first time.
Tsukasa’s lightly tracing fingertips just lulled her further into rest; his actions being such a contrast from before made her body totally relaxed. Before falling asleep though, she whispers one more thing to her older brother, “I’ll always love you too.”
