Today was a perfect day.

Snacks, video games, manga, and cola. All of the things Umaru loved surrounded her as she lay lazily on the floor. Wrappers were discarded haphazardly around the room, and Umaru had her nose buried in the latest comic magazine. There was no school that day, and her big brother was away at work. Put simply, today was nothing short of heaven.

Umaru hated going to school. She hated going out in general. When she had to go to school, she put on a facade of the perfect honor student with no interest in base pleasures like video games and junk food, but putting up this facade took a lot of energy, and it totally wore her out. It wasn't who she really was.

The true Umaru was a complete degenerate and a slob. She would stay up until the early morning hours playing video games, she would eat so much junk food that she passed out from the sugar rush, she would indulge in some internet shitposting while downing an entire liter of cola. That was who she truly was, and it was on days like today that she could go all out and truly feel comfortable in her own skin.

Sometimes, when her brother was away, she'd even indulge in some seedy corners of the internet where she could go to satisfy her base urges. Mostly foreign sites accessed through a vpn. She knew enough English from school to navigate the sites just fine, and she was rewarded for her efforts. The Japanese sites kept everything censored, and she wasn't really a fan of how the girls moaned and whined. The foreign sites had the good shit that she was really looking for.

She showed at least one version of the degenerate side of herself to her brother all the time. The one that played video games and gorged on junk food. This didn't bother her, and she didn't really care what he thought about that. But this other side, the one accessing foreign porn sites and using them for her own purposes, this was a side of herself that she could never show him. It just wasn't something that brothers and sisters talked about openly.

This made a day like today all the more perfect. With her brother gone until late into the evening, she could game, snack, and masturbate to her heart's content without a care in the world. No one could stop her. No one would judge her. It was just Umaru, the computer, and…

She nearly jumped out of her chair as she heard the lock to the apartment click open. Her pants were down, her fingers deep inside herself, and the computer screen showed a foreign man with a huge, throbbing erection.

She had never expected him to come home in the middle of a work day. She hadn't prepared for this. But she had to act fast. She had only a few seconds before he opened the door and saw her in this state. Quickly she keyed in the emergency abort, typing in alt+f4 quicker than she ever had before. She grabbed a nearby blanket and threw it over herself, covering her exposed bottom half just as the light from the outside struck the apartment wall.

A wave of summer heat washed over the room as Taihei walked in, leaving his shoes in the entranceway. He wiped the sweat off his brow with a sigh. It looked like he had been running. Her heart pounded audibly in her ears.

"He-Hey Umaru," said Taihei, taking deep and shuddering breaths. He bent over as he caught his breath. She took the opportunity to slowly and quietly pull up her pants. It was lucky that she was wearing pajama bottoms as they were much easier to pull up. She wiped her hand clean on the inside of the blanket.

"I forgot to send that report I've been working on," her brother continued as he stood up, "My boss really gave me trouble about it. It seems that the client wants it right away, so I ran back here. Can I use the computer?"

Without a word Umaru pushed the chair away from the computer desk, giving Taihei space to use the machine. She couldn't believe her luck. She had been so close to being found out. She was shaking from the burst of adrenaline that was pulsing through her body. She would have to take some extra precautions from now on.

Taihei clicked around on the computer for a little while, emailing a document off he his office. Umaru said nothing, her heart still beating wildly out of her chest as she watched him click around.

"There. It's sent," he said with a sigh of relief, "I should have remembered to send that before I went to sleep."

She was still in shock. In the end, she was able to choke out a single word.

"Y-Yeah…"

"Well I'd better get back," he said, unfazed by her strange behavior, "My boss is probably gonna yell at me again…"

Umaru averted her eyes.

"See you later and don't play games all day."

She nodded, she could feel a burning sensation in her cheeks. It was a blessing that the room was still dark.

"And don't eat too many snacks," her brother said as he pulled on his shoes, "Let's eat a proper dinner tonight."

He opened the door and left without another word, the lock clicked sharply behind him, leaving Umaru alone and trembling as her heart finally began to slow.

Maybe she would just masturbate in the bathroom from now on.

It was a few hours later and her brother had not come back. He probably wouldn't be home until 9 or 10 that night. His job was currently in one of its many busy seasons, and he had to work overtime a lot. Although she could be reasonably sure that he wouldn't come back, Umaru felt no desire to try and masturbate again. The shock of almost being caught had gotten to her, and the burning desire she had felt earlier in the day had all but vanished. She lazed around on the floor, unsure of what she wanted to do. She had calmed down a little, at least. Maybe she could still salvage what was left of her perfect day.

Manga! She would read manga! There was a volume she had picked up at the bookstore the other day, but she had been so sleepy from school that day that she hadn't read it yet. Where had it gone? Her brother had cleaned up her mess while she slept, and she had no idea where he had put it. She would just have to go digging.

She buried herself into the closet. There was a veritable mountain of manga stashed inside, belonging both to her and to her brother. The only question was where her brother had put her volume.

She started digging. It had to be in here somewhere, and it was really important that she figured out where it was. The volume featured a new chapter in a series she liked, so she had to find out what happened next in the story.

She dug deep searching for the volume, tossing book after book over her shoulder as she dug deeper and deeper. Why was it that you always seem to find things in the last place you look?

She opened up the final box. She wasn't sure why her brother had stashed it in here. It was the very last box, pushed all the way in the back. But she hadn't found the volume in any of the other boxes, so it just had to be in this one.

She tore open the box, annoyed that it was taking so long to find one volume of manga. She lifted the cardboard flaps and peered inside. And her eyes opened wide.

What… What IS this?

The box wasn't filled with manga. It was filled with… DVDs. Lots of DVDs. Her jaw fell open as she picked up one of the plastic cases. On the front cover was an image of a girl wearing a school uniform. She stared deep into the camera, a look of innocence painted on her face. She sat on what looked like a school desk, and you could clearly see her underwear peeking out from beneath her skirt.

She turned the case over and nearly choked with shock. On the back side of the case were images of young girls with their tits out. One of them looked like she was in pain as a man railed her from behind. Another had her mouth wide open as she took a pixelated cock deep down her throat. Yet another held her eyes firmly closed, a large load of semen painting her face.

This was porn. She had found her brother's porn. And this wasn't your typical run of the mill stuff, this was truly degenerate porn. She had been to enough seedy corners of the internet to know the difference.

She had never known Taihei to watch porn. Of course, porn consumption wasn't something he would actively share with her, but she was somewhat shocked nonetheless. Her brother just didn't seem the type to be interested in collecting porn. And certainly not this kind.

When did he even get the chance to watch it? He was at work when she was away at school, and she was usually at home being a slob when he wasn't working. Maybe when she went out with her friends?

She was a little flustered that she had found her brother's porn stash, and she was a bit disturbed at the types of porn he was into. As she dug deeper and deeper she found all kinds of disgusting stuff. But her curiosity kept her going. She felt a little less bad about almost being caught, at least.

A lot of the porn featured young girls who looked her age. Many of them were wearing school uniforms. She had to wonder… Did Taihei have a high schooler fetish? Did he… Look at her like he did the girls in these videos?

She realized that she had been snooping a bit too much. DVDs were spread all over the place. She should clean them up. Her brother's porn was his own business. She shouldn't pry too much. And besides, her manga definitely wasn't in this box.

She started putting the DVDs away, chuckling to herself slightly as she got another look at some of the weirder entries. She should probably be disgusted and horrified, but it wasn't like she had much ground to stand on herself. Her tastes in porn were just as weird and degenerate.

She put the box away, careful to place it in the exact orientation in which she had found it. She did not want him knowing that she had seen inside that box. She placed the other boxes of manga back where she had found them, wondering where the hell her lost volume could have gone.

She searched around the room. If it wasn't in the closet, it had to be around somewhere. She searched around the room, turning things over until she finally looked underneath her brother's bed.

And there it was. Her brother had not put it away in storage after all. She must have kicked it under the bed by accident.

She snatched up the volume and sat down to read. She tried to focus on the story, but she could not get the images of the girls in her brother's porn DVDs out of her mind. Just because he watched porn themed around high school girls didn't mean he was interested in her, did it? He didn't want to do those kinds of things to her, did he? Or was he interested in one of her friends?

She pushed it out of her mind. Porn wasn't real life. She knew that these were probably just fantasies to him. She was the exact same, and she didn't exactly have room to judge.

She couldn't focus on reading. She had eaten too many snacks again, and she could feel a sugar crash coming on. She would go to sleep. She closed her eyes as she slowly drifted away, her mind filled with images of her brother's porn collection.

She just couldn't shake the images.

The porn. She wasn't trying to blame or judge her brother for it. After all, she was an avid consumer of the stuff herself.

But still. This was her brother. Probably everyone watched porn and just kept it secret, but she had never thought about her brother that way. She'd never even wanted to think about him that way.

Not to mention how degenerate the porn she'd found was. She wouldn't be as surprised if she'd found some more vanilla stuff… Like the usual porn with romantic undertones and done mostly in the missionary position, but that wasn't the case. Taihei was in deep. He was into the weird shit.

Kind of like she was.

…

She had to try to put it out of her mind. She couldn't look him in the eyes now. Soon he'd get suspicious. What if he found out that she'd seen? How would he react? It was awfully dangerous of him to keep all that stuff in the same apartment where he lived with his sister. What was he thinking?

She sighed. It was no use. She would just have to live with the fact that her brother was a porn addicted degenerate, just the same as her.

"Something wrong?"

Umaru nearly jumped out of her seat. She'd forgotten that he was there. She had been so lost in her thoughts that she had tuned him out.

"N-nothing!" she said, her voice cracking, "Nothing at all!"

Taihei stared at her with a puzzled expression on his face. Did he know? Did he suspect that something was wrong with her?

He stared a moment longer. She averted her eyes, her heart racing again.

"Well. Dinner's ready soon. Find a good stopping point on your game."

Umaru looked down at the handheld in her lap. Her game. She hadn't even been playing it. She'd been staring at the title screen for who knew how long. She hoped he hadn't noticed.

She could turn it off for now.

That night, Umaru lay awake on the apartment floor.

Taihei slept peacefully next to her, no more than five feet away. The sound of his soft breathing filled her ears as his chest gently rose and fell. This was her brother. This was the man who watched porn of make believe high schoolers guzzling cum and putting their bodies on full display. Porn with girls who were not really her age, but were playing the part well nonetheless. This was the man who had an entire box full of DVDs filled with porn well beyond that which the average person would even think about watching. The content was slightly different, but this was the man who watched porn that was just as degenerate as what she watched.

She watched him sleep as she pondered the implications. Was Taihei frustrated? Did he not get enough action that he had resorted to watching stuff like this? Was it because of her? Because she was always there and he wasn't able to bring a girl over?

She understood the frustration. She too watched porn due to a complete lack of sexual activity. Her body was full to the brim with angst and hormones. Like everyone else around her, she wanted nothing more than to get laid. In truth, she could probably have any boy she wanted with her good looks and grades. She was the darling of her school, loved by everyone.

But she couldn't do that. Any boy she got to know well enough would find out about her lifestyle. How in secret she would binge snack foods and play video games all day. Something that she was very good at hiding while she was at school. She couldn't get close to a boy and allow him find out. He'd probably be repulsed. He'd probably tell everyone! And then the whole school would know! She couldn't allow that to happen. Not when she'd worked so hard to craft the facade she lived each and every day. And she wasn't about to give up her lifestyle, either.

Her brother was in the same boat as she was. He hid it well, but it was clear that he too had been driven nearly mad with celibacy. She knew well enough that it took many years of little to no action to drive a person to watch the kind of porn that he did.

For a brief moment, an image flashed across Umaru's mind. One that caused her to blush and sent her whirling with embarrassment.

No. No. What the hell was that? How could something like that even occur to her? That was just disgusting.

He was her brother! That's not something she should even be considering! Still…

They were both in the same boat. She was the only woman in his life, and he the only man in hers. They'd shared this apartment in close quarters for a long time now, and it wasn't like anyone had to know…

Would it really be so strange?

She shook her head. She'd read too much smutty manga where the brother and sister get together. She was being ridiculous. Sexually frustrated or no, it wasn't like Taihei would even be interested. She shouldn't even be interested.

She turned herself over, facing away from him. How would she even start such a thing, assuming she were interested? The whole thing was ridiculous.

She turned her head to look at him once more. He was still soundly asleep.

Oh no. She couldn't deny it anymore. Maybe she really did need to get laid. Maybe she should just accept the next idiot at school who confessed his love to her and take him to a love hotel to get these thoughts out of her head.

But as sick as it was, as much as she knew that it was wrong, she knew that she would do it. If her brother were on the same page, she would do it. She would have sex with him.

And why not? She loved her brother. He was the only person in her life who had ever cared for her. The only one who had, as much as he complained, accepted her for who she was. She was sure that she wasn't the only one who secretly harbored feelings like this.

But it was silly anyway. He'd never be interested. What was she even thinking?

She turned over again and shut her eyes tight, willing herself to go to sleep. Maybe these thoughts would be gone by morning.

Umaru blushed deeply as her brother's cock rose into the air, twitching and trembling as it grew two or three sizes. She knelt on the floor, her body exposed to the open air and dotted with goosebumps. A wave of anticipation shook through her body. His cock stood at full mast now. Trembling just inches from her face. She'd always wondered what they tasted like.

She opened her mouth wide, extending her tongue outwards. It was larger than she expected. Was it going to fit? She opened a little wider, closing her eyes as she approached, shivering with anticipation at her first ever taste of cock.

"Hey."

Umaru's eyes opened. Her brother was staring down at her, a puzzled expression on his face.

"You okay? You were groaning in your sleep. Have a nightmare?"

She frowned up at him. Why did he have to wake her up? Her dream had just been getting good. She sat up and rubbed her eyes.

"No," she said, "It's nothing."

She realized just how exposed she was. It was something she hadn't really thought about before, but now that she was seeing her brother in this way… She couldn't help but feel somewhat embarrassed.

Her hair was disheveled and her breasts were free, covered only by a loose fitting T shirt. The collar stretched downwards to the point that her cleavage was clearly visible. Her shorts left little to the imagination, riding high up her thighs. She was very vulnerable. Her body was on display for him. She had always slept this way, it was more comfortable. But she had thought so little of it up until now. She was already far more intimate with her brother than she really ought to be. Most siblings would not sleep so close and so underdressed. She supposed it was an effect of the long period they had lived together in the same room, but why had it never bothered her before? She could not help but blush.

Taihei looked perplexed.

"Are you feeling okay? Want me to call the school?"

She shook her head. He just didn't get it.

"No, no. I'm fine."

She should cover up. Sleeping with her body on display like this in the same room as her brother was shameful. Or… perhaps she should go even further? Would he notice her then?

"Well…" Taihei continued, "Don't take too long getting ready. You'll be late for school. I have to leave for work, so see you later."

She mumbled out a goodbye as Taihei put on his shoes and walked out the door. The searing heat of the sun filled the room briefly as he opened it. It was July. The height of the summer, and truly awful out there.

The heat…

It was an interesting plan. Even at night the temperatures were nigh unbearable. Taihei liked to keep the air conditioner off to save money, much to Umaru's discontent.

That night she would be bold. She'd pretend it was the heat. She'd bare even more of her body to him. Maybe then he'd notice her. Maybe then she'd get laid. Maybe then she could get these damn feelings to go away.

She pulled off her nightclothes in a flustered fit and headed for the shower.

That night, Umaru sat in the bathroom. It was almost time to put her plan into action. She had discarded all of her clothes save her underwear, and her breasts were out and on full display.

That night was a scorcher, and Taihei had not turned on the air, cheapskate that he was. If anything, it was his fault that she wanted to sleep in the nude. Would he really believe that she was doing this just because of the heat?

She felt silly. It wasn't like she had done this before on all the other hot nights they had spent together. He was sure to be surprised, or weirded out.

But maybe, just maybe if she reminded him that she was a girl, showed him that she looked just like the girls in his porn DVDs, maybe then she could get something started. She knew that he was secretly a complete degenerate, just as she was. So the chance at least wasn't zero.

Here goes.

She stepped out of the bathroom. The lights were off in the apartment, and a faint light could be seen from Taihei's bed as he scrolled on his phone in the dim light. He was getting ready to sleep. He always browsed his phone a little bit before bed.

"Don't stay up too late tonight, Umaru," he mumbled sleepily, "I know it's Friday but the boss called me in for overtime tomorrow, so please don't keep me awake."

He hadn't noticed her yet. He was too busy looking at his phone. Should she be forward? Should she pretend like nothing was different? Should she act embarrassed? Should she just give it up and go back to put on her clothes?

She stepped closer to him, her heart pounding in her chest. This was so stupid. What was she doing? He was going to think she was nuts.

"Um. Big brother?"

"Mm?"

He didn't look over at her.

"I… Left my nightclothes in the closet. Can you close your eyes?"

"Sure. I won't look."

Enough of this. This was dumb. He wasn't going to give her what she wanted just because she showed him her body under some pretext that it was too hot. She'd have to be forward with him. She'd have to show him exactly what she wanted. There was no way he was going to notice her otherwise.

She walked closer to him, her heart beating rapidly. He had his eyes covered, just as he said he would. She paused.

"Did you grab them yet?" He asked impatiently.

Now.

She quickly pushed herself under the covers, embracing him tightly and pushing her body against his. She held tight and did not let go. Not even when he abruptly opened his eyes and tried to squirm away from her.

"What are y-"

She placed a hand on his crotch. She could feel him steadily growing beneath his underwear. It was the first time she had ever been this close to a penis.

He tried to protest, but she quieted him with her lips, locking them with his own.

Her first kiss.

Soon, he relaxed. The message was clear. He was probably confused and his mind was surely whirling with a million questions, but the message was clear. She wanted him. And it looked like he wasn't going to put up a fight.

Umaru cautiously raised the waistband of his underwear, still unsure if he would push her away or not. When he offered no resistance, she carefully inserted her hand underneath, taking his penis in her hand for the first time. It was solid, warm, and twitching slightly with anticipation.

She hadn't done anything like this before. She hoped that he liked it. She had watched plenty of sex on porn sites, but doing it in person was a little different. Much more… personal. And far more awkward than she expected. She just didn't know if what she was doing was good or not.

She started to pull up and down, jerking her brother as she had seen many girls do online. Should she go faster? She didn't want to hurt him, but she also wanted him to enjoy it. She didn't want this to be the only time.

She pulled away from his lips, taking a gasp for air. Taihei took the chance to speak.

"Umaru… We shouldn't-"

She cut him off.

"You haven't stopped me yet," she said as she pushed her head into the crook of his neck, "You want this too, so just let me do this."

With her free hand, Umaru guided her brother's hand to her chest, his palm making contact as he let out a shuddering breath.

"I want this," she said, "I really do. So don't say any more."

With that, Taihei seemed to have given in. He took hold of her breast, fondling gently. His hand squeezed her lightly and then retracted again in a kneading motion. Umaru's breath began to quicken as a burning desire grew throughout her body.

She wanted to try something new now. She let go of his cock and slid two of her fingers beneath his waistline, pulling his underwear downwards. He lifted his bottom half off the bed to help her do it. It seemed that he wanted this too. He was not going to fight her.

She could easily see his cock now in the dim light. It was smaller than some of the cocks she had seen in porn, but she knew that they weren't usually so big. Still… To see one in person was pretty different from seeing one on a computer screen, and she started to worry if it would hurt.

Should she try giving him a blowjob? She'd never done that before. Or should they just go straight to sex? She wasn't really sure which she wanted to do. She wasn't sure what she was ready for yet. She was sure any blowjob she tried to give would be terrible, but was she ready to go all the way with him?

Taihei sat up suddenly and placed his hand on the top of her head. She jumped. She had not been expecting him to take the lead. With a gentle push, he guided her head downwards, pushing her closer and closer to the tip of his penis.

Before she knew what was happening, her lips were just inches from the head of his cock. She froze, her heart racing. She didn't know what to do. She hadn't mentally prepared herself for this yet. She hadn't expected him to be so bold.

He kept pushing, gently but with a bit of force, and her lips were now touching the head of his cock, kissing it as she had been kissing his lips before. Her first taste. It was enough to convince her, and she slowly, carefully opened her mouth.

The first inch or so steadily pushed past her lips. A solid, sweaty taste that was definitely not what she was expecting. But… She wouldn't say it was a bad taste, either.

She was running into a problem, though. He wasn't pushing anymore, but she could already feel herself starting to gag. She froze with her brother's cock partway inside her mouth, willing herself to go further but unable to do so. She wasn't ready for this yet. She had to pull away.

She pulled off of him and started to cough. She felt terrible about it, she didn't want him to think she didn't like it. But she just couldn't go any further than that. She took some deep breaths as she regained her composure.

"S-Sorry," she blurted out.

Her brother shook his head.

"No, I'm sorry. I shouldn't have rushed you like that."

Umaru took his cock in hand and started to pull again. She wanted him to know that she was still very much interested.

"Maybe next time," she said, embarrassed, "If you're willing?"

Taihei nodded, pulling her into an embrace.

"I'm willing."

She couldn't suck his dick. Not yet, anyway. And she wasn't sure if she was ready to go all the way, either. But she still wanted this night to be special. She still wanted to enjoy this. What if she… What if she tried licking it? Would he like that?

It was worth a try. She couldn't push it very far inside her mouth, but licking it was something she could try. She bent at the waist and went for his cock one more time.

"Umaru. You don't have to-"

Taihei's voice was cut off as the surface of her tongue made contact with his shaft. She licked it gently from base to tip, aiming for full contact. His entire body shuddered. His cock stiffened further, twitching faintly with renewed ardor.

She went a few times more, starting at the base and steadily working her way up to the tip. She tried her best to make full contact, and she ran her tongue gently over the tip with each pass, even going as far as to push it ever so slightly past her lips a couple of times.

After a number of passes, his body suddenly stiffened. She could feel his heartbeat quickening through her tongue. Before she could react, a fountain of cum erupted from her brother's cock, leaking down the sides and landing straight on top of her tongue.

She jumped back in surprise, a foul, pungent taste quickly overwhelming her senses. Her brother spasmed a few more times, cum leaking down the sides of his cock. It was making a mess, and a strong stench filled the room.

She hadn't bargained for this. She hadn't really been planning on getting her first taste of cum that day. She had envisioned something a lot more romantic and far less vulgar.

It tasted terrible, and it was all she could do not to vomit. She cupped her hands underneath her chin, spitting the fluid violently onto her palms. How did girls in porn handle this stuff? Did they just get used to it over time? It was disgusting.

Taihei looked apologetic.

"I'm sorry," he began, "I should have warned you. It can sometimes come without warning."

She was frankly disgusted, but she couldn't blame him for it. This was a taste she'd have to get used to if she wanted to go any further with him. She'd have to try and get used to it.

She went to wash her hands… And to rinse out her mouth. She could only imagine what it would be like if she took that stuff further down her throat, and not just on her tongue. Why did it have to taste so bad?

She hoped he didn't hate her for it.

When she returned, Taihei welcomed her with open arms, inviting her to sleep next to him. He didn't seem to be angry, and he held her close that night, stroking her hair as they slowly drifted off to sleep.

For all of its various mishaps, it seemed that Umaru's plan had gone well. She had shown her brother what she wanted, and he had accepted her without any judgement.

And soon she would try to go even further.

It didn't take long for the two of them to start fucking almost daily. Years of built up tension and secretly harbored feelings were let go all at once, and nothing could stand in their way.

The first few times were a little awkward, and it took time for Umaru to get completely comfortable with all the new sensations she was feeling, but they soon became intimately familiar with each other's bodies and preferences. Days turned into weeks, and weeks into months. Over time, Umaru even began to enjoy the taste of her brother's semen.

She opened her mouth wide. Her brother's body twitched, and he let out a soft groan as she pushed the tip of his penis slowly beyond her lips. His fingertips stroked the roots of her hair, pushing lightly against her scalp as she sunk his cock deeper and deeper. His cock was warm and firm, pulsing slightly in time with his heartbeat. It didn't bother her anymore, and she had plenty of practice with this sort of thing by now. She closed her eyes, savoring the deep connection she felt with her brother, a connection overflowing with intimacy and with trust. She pushed further, sliding his cock against her tongue as she allowed him to fill her up. She went back and forth on it a few times, pushing it deeper with each successive thrust. She took his balls in her palm, fondling them as she reached the end of his length, her throat opening up to him as she focused on trying not to choke.

It was coming. She could tell by the change in his breathing. She pulled away from his cock, taking it in hand as it glistened with her spit. She looked him in the eyes, smirking as she stroked him with vigor, resting the tip of his cock on her nose.

It came in spasms, and the warm, slippery liquid arrived at the bridge of her nose. It congealed there as she pulled the tip of his penis back into her mouth, swallowing it once more as it disappeared beyond her lips, his cum still coloring her face.

Taihei put a hand on her head and gave her a light push. She knew what was coming next, and her body shuddered with anticipation. As he kindly and yet forcefully pushed her off of his dick, she felt as if her whole body would explode with the tension that was building. She watched him excitedly as he rolled a condom onto his cock, and she scooped up the cum resting on her nose with her fingers, licking them clean and shaking with pleasure at the strong, bitter taste.

He took her by the waist, digging his thumbs into her skin. She yelped with the sudden pain, but her complaints quickly changed into deep, passionate moans as he pushed the hot, twitching tip of his cock just barely past her folds.

And then he stopped, holding himself partway inside. A grin shot across his face as he enjoyed the sight of her in such a state. Breathing heavily and desperate for the rest.

She took him by the back of the neck, pulling him into a kiss and coaxing him to push himself further. She wrapped her tongue into his, and he was convinced to give her the rest of it. She moaned into his open mouth as he finally pushed all the way inside, the sound of her voice softly muffled.

He was so big. So firm. So… comfortable.

Her soft, muffled whines of pleasure quickly transformed into crescendoing wails as he fiercely thrust his way inside. His skin collided with her own in successive smacks as he sent his sister into a building frenzy.

Her mind was overflowing with emotion. Her face flushed with red as her entire body tingled. Tears filled her eyes as she was overwhelmed. Her entire world collapsed as she fell into the abyss, her voice cracking as she whimpered and groaned with overflowing sensation.

She was shaking. He had pushed her over the edge to a pleasure beyond what she had thought possible. He had already pushed her beyond the boundary, and yet still he kept going. She shook her head back and forth, mewling weakly as he pushed her further and further into the depths.

His stamina was impressive. He had far outlasted what she had been able to handle. But even he would soon reach his breaking point. Umaru lay before him on the apartment floor, quivering with a pleasure far outside what she had bargained for, and with his cock buried deep within her body. Her chest heaved up and down as she struggled to catch her breath, her young, supple breasts quivering with her uneven breathing. Beads of sweat gathered at her brow, her eyes closed tight and flowing messily with tears. She squirmed slightly as he pressed himself as deep as he could go, her waist swaying slightly back and forth as he pushed. She let out a soft cry as he reached his end.

She jumped with shock as he released himself deep inside of her body. His face contorted as he gripped her tightly by the roots of her hair. In quick jolts of ecstasy the waves off of his seed arrived, filling the deepest parts of her insides with a warm, comforting sensation.

The condom had broke. They had been too rough. She didn't want to risk getting pregnant, but it was all she could do to hold the overwhelming sensations at bay, and she hadn't tried to slow him down.

Soon he collapsed onto her body, breathing heavily as he pressed his body into hers. She stroked him by the back of his head, kissing him lightly on the cheek as her brother's sperm slowly leaked out and soaked into the floor.

This wasn't the first time this had happened. She would just have to make sure to take her morning after pill.

Why did he have to come visit her at school?

No one was supposed to know about this. They were supposed to do this kind of thing where no one could see. Doing it at her school was just risking too much. What if someone found out? What was he thinking?

But… Taihei had come to visit her at school that day, telling the office staff that he'd come to deliver one of her textbooks.

He'd been gone on a business trip for the last week, and had arrived back home in the middle of the day. She hadn't seen him in all that time, so Umaru was eager to let this happen. Still, she couldn't help but hate him a little for coming to her school and getting her all worked up where people could see her.

They'd found an open closet. It was filled with the cleaning supplies the students used to clean the building when classes were over for the day. Classes were still in session, and Umaru had snuck out. No one would come here until the end of the day, and as long as they were quick, no one would wonder where she had gone, either.

Probably.

They closed the door behind them and Umaru sat down on a cart full of supplies. She breathed heavily in the thick, musty air of the cleaning closet as her brother touched her for the first time in days.

He'd undone the top few buttons of her summer uniform, and her breasts hung limply into the open air. He grasped at one of them with force, squeezing hard as he slipped her nipple into his mouth, running his tongue over the tips of her breasts. She stifled a squeal as her nipples grew stiff and erect, her body growing hot with pain and desire.

He grasped at the fat of her breasts with his fingertips, rewarded with stifled whimpers as he pinched down hard. Unable to reach him with her hands, Umaru placed her foot on the crotch of her brother's pants, tracing his erection with her toes. The closet was getting warmer and warmer, and she felt a bead of sweat roll down her back. It was another hot day, and their combined body heat was making the closet even warmer than the hallway. The air grew thick and heavy, and as she stroked the shaft of his cock, holding it between her toes, she worried that she might start to lose her breath.

Taihei tensed, backing away from her and holding his hands to his crotch.

"I'm about to explode, Umaru," he said, panting weakly into the darkness, "I've been thinking about you all week. I can't take it much longer. Suck my dick."

She didn't need to be asked twice. She had been waiting for him to say that. Umaru jumped down from the cart, her breasts shaking slightly with the effort. She grasped desperately at his belt, working to free his cock between labored breaths. She pulled the belt free and unzipped his pants, freeing his cock from beneath them. The tip was wet with smeared beads of precum, and the inside of his underwear was slippery and stained with it. A powerful stench of sweat was beginning to fill the room, and Umaru could feel the hair on her forehead sticking messily to her skin. His cock pulsed as she took it firmly in hand, a little damp with sweat. He had been holding it in for her, and he wasn't going to last very long.

She swallowed his cock, pressing it far down her throat. She pushed herself as far forward as she could go, her lips nearly touching the skin at his cock's base. A small choking noise came from the back of her throat as she reached the end. She had pushed a bit too far in her eagerness, and she coughed a little, the sound muffled by the cock in her airway. But she wasn't about to stop. She pulled backward before pushing herself fully forward gain, rolling her tongue over him eagerly.

He placed a fingertip on her forehead as he groaned a little too loudly, pushing her lightly backwards. She knew what this meant. He didn't want her to swallow it this time. He wanted to see it on her face. Sweat was beading up on her body now, dampening her chest and her face. The closet was really far too hot for them to be doing this. But it was too late now. They would just have to see it through.

She took a deep gasp of dense, musty air as she allowed herself to be pushed backwards, her tongue outstretched and her mouth open. Soon after, Taihei groaned as the hot liquid splattered his sister in the face, jolting out in a series of spasms. She closed her eyes as it landed in messy clumps all over her face, the first covering one of her eyes. His cum was runny and slick in the heat, running down her face as it mixed with the sweat that had collected there.

It drained onto her bottom lip and down onto her chin, oozing onto her uniform shirt in messy, trickling lines. Taihei stroked himself vigorously as the last bits of cum shot out onto his little sister, landing in splotches on her exposed chest as he moaned at a volume that was sure to get them caught. The stench of cum and sweat filled the small closet, and Umaru opened her clean eye to take stock of herself.

He had saved up a lot for her, and she was covered in the stuff. A thin line painted her face from her chin to her forehead, and her breasts were covered in splotches here and there. Her uniform was ruined. The shirt still hung limply from her shoulders, and a splotch of her brother's cum stained the front part of it near her chest. Cum dripped down her front and onto her belly, aided by the heat and sweat. It gathered at her waist, soaking into her underwear and skirt.

Her brother's cock hung limply, finally released after days of pent up tension. A bead of sperm collected at its tip, and Umaru licked him clean with the tip of her tongue.

Taihei raised his phone, pointing its camera at her and turning on the flash. She closed her eye as she was blinded with the sudden brightness, her body glistening as her brother's cum reflected the light. She opened her eye as he showed her the photo, the head of his dick still resting on the tip of her tongue.

What was she going to do? She hadn't brought a change of clothes, and her uniform was ruined. She couldn't go out wearing it like this, but she still had to go back to class. It occurred to her then that she had her gym clothes in her bag, so she'd just have to wear that. She wiped her face and body as clean as she could with the ruined shirt, tossing it to the side as she kneeled topless before her brother. He pulled up his pants and clasped his belt. They were done for now.

He pulled her into a passionate kiss, driving his fingers under her skirt and through her underwear, pressing them sharply against her pussy. She placed a hand on his chest and gently pushed him away.

She had to go. Someone would start to wonder where she had gone. And they couldn't afford to be caught. They would continue this later. She unzipped her uniform skirt and pulled it down and off, pulling out her gym clothes from her bag. If anyone asked, she would make the excuse that she had spilled a drink on her uniform. She hoped that she didn't smell too strongly of cum.

Taihei took her uniform with him, promising to dispose of it at home where no one would find it. They parted with another passionate kiss before Umaru walked back to her classroom.

On her way, she stopped by the bathroom to check herself in the mirror. She was lucky there was no one in the hallway. She was drenched with sweat, and a small splotch of cum remained in her bangs. She scooped up as much as she could with her fingers and stuck them in her mouth, closing her eyes as she relished the flavor. She thoroughly washed her face and did her best to wipe her hair clean, checking herself over and over in the mirror to make sure there was none left. Her hair was a mess, and she was pretty sure that she smelled. She tried spraying some perfume, hoping that it would mask the smell a little. If anyone asked, she'd say she ran home in the heat to get some forgotten homework. A lame story, but it was all she could think of.

She made her way back to class as she thought about what she would be doing with Taihei that night.

Umaru trembled as her brother parted the lips of her pussy ever so slightly, the tip of his cock resting just barely inside. He loved to tease her like this, and she always had to beg him to push it further in.

She lay before him on his bed, her eyes closed and her hips squirming with expectation. They had long since stopped using condoms, and the raw sensation of his cock pressed directly against her body sent her heart racing.

"What do you say?"

"Please," she groaned weakly.

He pulled away, taking his cock away from her. She opened her eyes, the desperation writ plain on her face. She had satisfied him already in the closet that day, but she hadn't had her share yet, and she needed to have her share.

"PLEASE, big brother," she pleaded, pulling on his hands weakly with her own, "Please. Please."

"And what will you do to earn it?" he asked, as if she hadn't already more than earned it.

She sat up, eagerly grasping for his cock and pushing it swiftly into her mouth, gulping it down as if her life depended on it.

"Good," he said, stroking the back of her head.

He grasped her by the shoulders and pushed her fiercely backwards. She landed on the bed, bouncing off of it as it shook on its springs. She smiled brightly. She would finally get what she wanted.

He parted the lips of her snatch once more, steadily inserting himself inch by inch. She closed her eyes and arched her back, the sensation of her walls being filled unleashing a tightness that had been trapped inside of her for days.

He reached the end, and Umaru's eyes opened wide, her breath shuddering as she whined with satisfaction. The neighbors could probably hear. But she didn't care. She wanted them to hear. She wanted everyone to know that she was getting fucked. She didn't want to hide it anymore. She wanted everyone to know just how happy they were.

Her brother held himself in place, locking his lips to the side of her neck, running his tongue over her skin as she stretched her head sideways, groaning as he worked away.

He pulled back, preparing for another thrust. He gave it to her slowly once more, dragging out the feelings of bliss that washed over her body as he went. She took him by the hand, placing his finger in her mouth as she sucked at it, eliciting a deep groan from him as she stuck his finger deep into her mouth.

She grabbed his ass with her free hand, prompting him to go faster. He pulled away from her neck and pulled his body off of her, grasping her by her waist and lifting her up. He kept himself pressed deep inside as he did so.

He was so strong.

He pulled her close to his chest as they both sat up. The skin of his chest met her own as her nipples grazed against him. He pushed on her back, pressing her body close to his own. Her breath quivered lightly.

He grasped at her thighs, his hands nearly encircling them as he squeezed a little too tightly. She squealed in protest, but she did not try to stop him. He began to push once more, lifting her into the air by her thighs, pounding her body down onto his cock in rhythmic slams.

Gravity helped him here. As he lifted her up with his vice like grip, her thighs screaming in pain, he then slammed her downwards with force, eliciting a painful, delighted cry each time.

She wasn't going to last long like this. The week she'd spent without him was driving her crazy. And he was being so rough.

It was too much. As he thrust her body violently down on his dick, her wails rose in a building crescendo. She cried and she screamed as she reached the end of her rope, ripples shooting through her sex starved body.

She collapsed into his arms, shoulders heaving with the effort, her forehead beading with sweat. He gently laid her down on the bed as she struggled to catch her breath. There was only one thing left to do now. His cock trembled in front of her face, bursting at the seams. She opened her mouth without another thought, bobbing her head back and forth as he released himself inside. She closed her eyes as she hungrily swallowed every drop.

He pulled his cock out of her mouth with an audible pop and she gasped for air, heaving her chest up and down. Her open mouth was decorated with lines of thick, oozing spittle. A mixture of cum and saliva. She turned to look at him, showing him the foul concoction inside.

She closed her eyes and swallowed.

"Are you his girlfriend?" the cop eyed her dubiously, "How old are you, miss?"

Someone had made a noise complaint. Umaru and Taihei were speaking with the cops. Their hair was disheveled and the apartment smelled of sweat. Taihei was shirtless and Umaru had pulled a blanket over her body, wrapping it tightly over her shoulders to conceal herself. It was clear to just about anyone what was going on.

"I'm twenty," she lied. She tried not to grasp at her crotch, which was burning with a throbbing pain. They had been far too rough, and it might take a while before she could walk straight again.

She didn't mind if the cops found out they were related. She didn't want to hide it anymore. As far as she was concerned, she was going to stay with Taihei for the rest of her life, so she should just be open about it. It might be a problem though if they found out that she was still in high school. She figured she could pass for twenty.

The cop grunted in acknowledgment, writing something on a piece of paper. He didn't seem to completely believe her, but he didn't press the issue further.

"And you're married? Dating? What's your relationship to him?"

"I'm his sister," she said without hesitation.

Taihei tensed a little at these words, but he didn't argue. She was done hiding, and her brother would have to learn to start being more open about it, too.

The cop looked up from his clipboard, staring her in the eyes. His reaction was not quite as extreme as she had expected, but she could see the disapproval in his eyes as he realized the implications.

"Well… There's nothing illegal about that, miss. Not in Japan, anyway. But that doesn't mean it's a good idea. You're sure he isn't forcing you to do this? You want to be here of your own free will? You shouldn't be sleeping around like this when you're still so young, anyway."

Umaru rolled her eyes. This kind of chauvinistic lecturing was common in Japan, especially from older men. And she didn't need this middle aged cop to tell her what to do. She could do what she damn well pleased with her own body.

"No. He isn't forcing me to do anything. I want to be here."

The cop looked to the side and sighed. He was visibly uncomfortable.

"Anyway, just keep it down," the cop continued, "Be mindful of your neighbors. We'll have to write you a citation if it happens again."

The cop handed Taihei a piece of paper. A formal warning. He then pulled a business card put of his pocket and handed it to Umaru.

"Now the way the law is written means there's nothing illegal about what you're doing here," the cop said, "But I think what you're doing is a mistake. You should be more careful, miss. And the young man here should be ashamed of himself."

"What we do in our own time is none of your business, sir," Umaru countered.

The cop sighed again. He wasn't going to get anywhere on this one.

"If you ever need help," he continued, "If he does something to you or if you need to talk to someone to get out of a tight spot, call the number on that card."

"I won't need to," Umaru said, defiant.

The cop shook his head.

"Excuse me," he said, staring Taihei aggressively in the eyes before turning away and walking out of sight.

People like him were never going to understand. And Umaru wasn't going to try and convince him.

Umaru loved her brother. She loved him even more now than she ever had.

Not only did he provide her with a place to live, food, and money for video games and manga, but now he provided her with something she never had been able to get before. Something she now didn't have to go out and find for herself.

Her brother gave everything to her, allowing her to live her perfect life filled with video games, manga, snacks, cola, and sex. She didn't know what she would do without him.

He'd been nicer to her, too. Ever since they'd started fucking, he hadn't scolded her so much for her hedonistic lifestyle. She could lounge around all she wanted, playing all the games she wanted and leaving snack wrappers all over the floor. He wouldn't scold her for it like he used to.

They still had to keep their relationship somewhat of a secret. Taihei could get fired from his job if it got out that he was sleeping with a high schooler, and his sister no less. And it wouldn't exactly be good for Umaru either if her school found out.

But Umaru would be graduating soon. And she planned to let the secret out after that point. She could never get married to him, but at least she could live her life with him authentically and without hiding. She would take the backlash that was sure to follow in stride.

Ebina in particular probably wouldn't talk to her anymore. But that was something Umaru was willing to risk. She loved him too much, and if Ebina was going to judge instead of being happy for her, then she could live with that.

Her life was nearly perfect now. She couldn't imagine a better scenario than the one she had. Cola, manga, snacks, and sex all available to her within a moment's notice.

And to think she had been weirded out by that box of DVDs.
