Kyousuke grunted in irritation as he shifted around uncomfortably, leaning against the concrete pillar behind him. His school shirt stuck to his skin in the most annoying places, while sweat trickled down the back of his neck from his hair, creating a truly annoying damp spot on his back. His uniform jacket was draped over his shoulder as it far too hot to wear, while his bag lay abandoned by his feet. He felt like a drink, but there were no vending machines in sight - and he couldn't leave, not yet. So he waited, suffering silently. If there was one type of weather people universally hated, it would have to be this.

Humidity was a bitch.

Sighing, he unbuttoned the upper most buttons of his shirt while fanning himself with his hand. His tie had been removed much earlier, stuffed into his bag haphazardly. The sky was overcast and ominously black, as it had been all day, but no rain had yet fallen. It was the type of weather that preceded a thunderstorm.

He just hoped it would wait until he got home.

A familiar chime sounded, signalling the end of the school day.

"Finally," he muttered, shifting again.

He had only been waiting a short while, but in this type of heat, it felt so much longer. His last class for the day had been study hall, so he had been able to leave a little early to make it here before the end of class. It hadn't been very far, as both schools were fairly close to home. It was then that he remembered that it wasn't just the heat that was making him uncomfortable, but the fact that he waiting in front of Kirino's middle-school.

When she saw him, he knew she was going to be pissed.

He had his reasons for waiting, however. Very legitimate reasons. Hopefully, that would be enough to stop the very likely onslaught he was moments from encountering.

Slowly but surely, students dressed in light blue and white begun to appear, making their way toward the gate he was leaning against. He got plenty of curious looks, but he ignored them in favour of looking for his sister, attempting to spy her unique hair colouring amongst the masses. Several minutes crawled by until he spotted her, leaving one of the buildings with-

-ah, crap.

He stood a little straighter, absentmindedly brushing his hand through his damp hair. His fringe was sticking to his forehead, which he hastily swiped away. It gave him a distinctly ruffled appearance. Bending down, he retrieved his bag, keeping a close eye on the approaching girls. He should have expected that Kirino wouldn't be alone. This was going to make matters even worse.

They hadn't noticed him yet, and he took this time to observe the pair as they came closer. Truly, Kirino and Ayase were both incredibly beautiful girls - no one could deny that. However, they were very different in their appearance and after a few moments, Kyousuke come to the conclusion that they were like night and day.

Kirino was all bright colours and wonderful smiles, and he believed she looked no better than when she was in the sun. Her hair was light brown and shimmered when under sunlight, and her skin was lightly tanned from all the time she spent outdoors running on the Track and Field team. Her wide, teal eyes were unique and shone brightly. She carried herself with such maturity that it was hard to believe she was only in middle-school.

Ayase, on the other hand, was cooler in appearance and more selective with her smiles, though they were no less wonderful. Her hair was a beautiful black and it contrasted sharply with her pale, porcelain hued skin that Kyousuke knew would look stunning under moonlight. Her soft, violet eyes were mysterious and he knew, from personal experience, that they could be rather frightening and passionate when angry.

Two beautiful girls, but so different.

Together, they were absolutely stunning.

Kyousuke watched as almost every male in the vicinity looked their way. Even just walking, they drew their eyes effortlessly. Without doubt, they were incredibly popular - several girls called out to them in greeting as they past.

He then blinked, surprised, as he watched a few boys approach his sister and her friend. They were close enough now that he could hear them and what he heard made him frown.

For some reason, hearing those boys hit on them pissed him off. He was already in a bad enough mood as it was, sticky with sweat.

He felt mildly embarrassed, listening to them trying to pick up his sister. Some of the lines they were using were truly awful, and he couldn't help but think that they were lucky that Kirino tended to keep her fiery temper in check around most people. Even so, Kyousuke could see she was getting annoyed by their persistence. Ayase was less subtle, glaring at them furiously, but they didn't seem to get the point.

"Good grief," he uttered, growing tired of waiting. His sister could be hopeless, sometimes. Waving his arm to catch their attention, he moved towards their little gathering.

Ayase was the first to notice him, her eyes widening in surprise. The anger on her face vanished, replaced by confusion. She looked so cute that Kyousuke wanted to snuggle her tight. "Ah-! Onii-san, what are you doing here?"

"Huh?" Kirino said, following Ayase's line of sight and finding her brother. "Wha-!"

"Before you get mad," he said calmly, ignoring the hostile looks he was receiving from the boys. He had stolen the attentions of the girls they were trying to woo, after all. "I have a perfectly good reason to be here."

Kirino and Ayase stared at him, causing the hair on the back of his neck to stand on end. It was pretty intense. "What's with those looks?"

He expected a scathing remark, but what he got were two flushed faces. That was odd.

"Hey man, who the hell are you?" one of the boys said rudely, stepping towards him. He had short brown hair and mean eyes. Kyousuke looked at him blankly. Was a middle-school kid really trying to intimidate him? What in the world...

He answered plainly. "Kousaka Kyousuke. You?"

"K-Kousaka?" he stammered, suddenly looking alarmed. He no longer looked like he was about to pick a fight. "Are you-?"

"I'm Kirino's older brother, yeah."

"Oh."

Well, this is awkward, Kyousuke thought, turning back to his sister and ignoring the wary looks he was now receiving from the boys.

"We are home alone tonight," he began, explaining his appearance. Kirino perked up. "Dad was invited to some work function and mum is going with him. They said you can invite someone over for the night, if you want. They left us some money for dinner - what do you feel like?"

"Ah - a-anything is fine."

Kyousuke frowned. Kirino was acting a bit weird. He had been expecting some sort of demand, but she was leaving it up to him. After a moment, he shrugged.

"Okay. Well, I'll see you later."

Turning toward the gate, he began to walk away. He was halfway down the street when he heard the sound of footsteps pounding the pavement behind him. Glancing over his shoulder, he saw Kirino with Ayase in tow. Pausing for them to catch up, he gave them both a questioning look as they panted, the short run sapping their strength in such conditions. They both looked relieved to be away from their enamoured classmates.

"Ayase is going to stay over," Kirino said in her usual arrogant way, though it was somewhat ruined when she wiped her forehead free of sweat. Whatever had been bothering her before was clearly gone, though. "If you try anything tonight, I'll kill you, understand?"

"Yeah, yeah."

That was the Kirino he knew. He could deal with that kind of reaction.

"How have you been, Onii-san?" Ayase asked politely, as if Kirino hadn't just threatened him with death. Kyousuke smiled at how lady-like she was acting, but kept it at that. He typically lost his head around Ayase - as she was his lovely angel, Ayase-tan~! - but his personal health in this situation won over. Kirino and Ayase together were just too dangerous to consider mucking around. "You aren't thinking anything perverted, are you?"

She had noticed his smile. So much for personal safety.

"Urk," he choked, wounded. "Why do you always think the worst of me, Ayase-san? It really hurts, you know."

"She knows what you are like," Kirino added scornfully, though Kyousuke noticed it was without any real heat. That's how most of her insults felt these days, no longer containing the sting they once did. "But don't worry, Ayase. I have this dog under control."

...DOG?

That stung.

"Who are you calling a dog?" he shouted indignantly.

"Who else?"

"Do I look like a dog to you?"

"You sit when I tell you too, right? You must be a dog."

"Tch, you brat."

"Do you hear something, Ayase?"

Kyousuke grit his teeth, about to retort when a cute giggle drew his attention. Kirino also looked surprised and gazed at her model friend, who was trying and failing to stifle her amusement behind a hand. She waved at them slyly, smiling widely. She then said something that brought both Kousaka siblings to a halt.

"Even though you look nothing alike, you really are related, aren't you?"

Kirino opened her mouth, paused, and then closed it again, looking stunned. Kyousuke choked for a second time.

"What is that supposed to mean?" Kirino grumbled, frowning cutely.

"I wonder," Ayase said teasingly, before skipping ahead with a laugh. "You two are pretty close." Kirino flushed and chased after her, shouting denials. Kyousuke shook his head and continued on behind them, thankful that Ayase was only teasing them about being close and not interrogating him.

When he arrived home, the place was silent. Kirino had gone with Ayase to her place, which was rather close by, so they could inform the young models parents about their plans. Pulling out his keys, he swiftly unlocked the door and announced himself out of habit.

Removing his shoes and slipping on his slippers, he ascended the stairs and entered his bedroom, throwing his bag on the ground near the end of his bed. Quickly undressing, he pulled on a pair of black shorts with a white stripe down the side and a dark blue t-shirt, before heading downstairs. His parents had left some money on the living room coffee table, which he scooped up before heading into the kitchen for a drink. He relished the feel of the refrigerated air on his damp skin as he pulled open the fridge door, before pouring himself a glass of orange juice.

"I'm home!" Kirino called out, followed by Ayase calling, "Pardon my intrusion."

They were quick.

They both entered the living room. Kirino was still in her school uniform, but Ayase was dressed in a very cute light purple dress with a small fashionable leather vest over the top. It was open in the front, drawing his eyes to her developing curves with the way it hugged her slender frame. Around her waist hung a loose leather belt with a great big buckle, which complimented the rest of the outfit nicely. Hanging from her shoulder was a backpack.

"Urgh," Kirino groaned, fanning herself. "It's so hot. I hate this weather."

"I'm heading out," Kyousuke spoke, finishing his drink. "I'm going to the store," he added, placing his glass in the sink. He asked as an afterthought, "You want anything?"

A year ago, Kyousuke would never have bothered asking such a question. A year ago, if had asked it, he would never have got a response. It showed how much things had changed in that time.

Kirino considered his words. "Ice cream."

"Flavour?"

"Strawberry, baka."

How was I supposed to know tha-never mind.

"Ayase-san? Would you like anything?"

She appeared startled for a moment, before giving him a suspicious once over, like she was checking for ulterior motives. Kirino copied her, suddenly looking disgruntled. What had he done?

"No, I'm fine. The ice cream will be enough, Onii-san."

Nodding, he headed out. The store was close by, but he made sure to take an umbrella in case the heavens decided to open up while he was out.

When he arrived, he almost didn't want to leave, as it was air conditioned and much more comfortable than outside. He loitered for a bit, cooling down as he examined several vegetables. He had decided on a simple stir fry dish as they were easy and quick to prepare, even with the use of fresh produce. Ordinarily, he would just buy a bag of assorted frozen vegetables and be done with it, but he felt like doing it properly this time - he wasn't exactly sure why. The sauce was covered, as they had everything he would ever need at home, so he was set there. He just needed to pick which meat to use.

What is Kirino's favourite? he thought idly, picking up an eggplant. He turned it over a few times before placing it in his basket before moving toward the onion bin. Beef, chicken or pork?

He didn't even realise he was basing his choice on what his sister liked rather than his own preference.

In the end, he picked beef. Paying for his goods - he almost forgot the strawberry ice cream, and had to quickly search for the freezer - he sighed in regret as he left the cool atmosphere of the store and stepped back into the rank humidity of the outside world. The only upside was that it hadn't started raining yet and he was able to make it all the way home without having to use his umbrella.

"I'm home."

He struggled with removing his shoes as he juggled the bags in his arms. He was pretty sure he looked quite humorous. Task complete, he then moved into the living room which he noticed was much cooler than before - the aircon had been turned on. Ayase and Kirino were seated on the couch, watching the big screen television and seemingly took no notice of his entrance. Kirino was no longer dressed in her school uniform, wearing a pair of short denim shorts and a snug pink singlet that was a little short and bared some of her toned stomach. He almost paused at that, but forced himself to move into the kitchen.

He quietly put the groceries away before grabbing three bowls from the nearby cupboard. The ice cream was a little soft from his walk back but that was fine. He disliked ice cream that was almost impossible to scoop and hard enough to bend spoons. Dividing three equal portions into each bowl, he put the ice cream away in the freezer and grabbed two extra spoons. Walking over into the living room, he placed two bowls on the coffee table, startling them from their show. Kyousuke glanced at the screen for a moment, recognising a rather popular drama that was airing lately. People were talking about it a lot at school.

"Ah - thank you, Onii-san." Ayase nodded politely and grabbed one of the bowls.

"Tch - you'd make a good butler, if nothing else, I suppose." Kirino was smiling when she said this, though. She seemed pleased, her eyes sparkling. Kyousuke felt strangely warm before he turned away quickly.

What the hell...

"I'll be upstairs," he muttered, gathering his bowl from the kitchen and leaving quickly. As he entered his bedroom, he noticed that rain was beginning to fall, beading on his window as it picked up in intensity. Small gusts of wind followed and Kyousuke watched as several trees swayed back and forth.

Sitting at his desk, he powered up Kirino's laptop. He momentarily thought about playing a game, but that was out of the question. The only games he had were eroge - imouto eroge, at that. There was no way in hell he was going to play those games when Ayase was in the house. Love Touch would have been fine, as it was a regular dating sim, but he had already cleared that as much as he could and Kirino had taken it back besides. Whispering loving words to the PSP was also not a very safe thing to do with Ayase around.

Surfing the internet, then.

"No porn," he said to himself, tasting his ice cream. It was really good. "Anything but porn."

He spent the next few hours browsing random sites, not doing anything in particular. He lost track of how many videos he watched and was completely absorbed in his mindless pursuit of entertainment that he didn't notice how strong the rain was falling, or how strong those wind gusts had become. It wasn't until he briefly glanced at the window that he realised how bad things had turned outside. They were definitely in for a storm tonight.

Stretching his back, he looked at the time and nodded to himself. It was a bit earlier than when they normally ate dinner, but that was fine - he was hungry, and they were probably hungry too. Gathering his dirty dishes, he powered down the laptop and made his way downstairs. The living room was empty which meant they were probably in Kirino's room. They had left the light on and the aircon was still keeping the temperature of the house bearable.

It didn't take very long to prepare the food for cooking. He diced the beef and onion, sliced the eggplant into thin slices and cut everything else into thin strips - picking a red capsicum over the green one for its visual appeal if nothing else. The sauce came next, Kyousuke carefully measuring each ingredient as he mixed them together. Someone like Manami would be able to do this part without having to measure anything, but he was a novice when it came to cooking while she was closer to master. He was just adding some crushed garlic and ginger to the sauce when Kirino and Ayase entered.

"Kanako said she has a concert coming up," Ayase was explaining. "And there must be a whole lot of new songs she has to learn, so she'll be pretty busy in the coming weeks. It's for that - ah... that anime she c-cosplays for."

"Dinner will be ready soon," Kyousuke called out, before Kirino could even contemplate going full-otaku on Ayase by mistake. The black haired model looked uncomfortable enough as it was, talking about cosplay. They both jumped, not having noticed him in the kitchen. "We are having stir-fry."

They both walked over and watched as he set the wok on the stove, lighting the gas element underneath. Pouring in a little oil, he waited until it was hot before adding the diced beef. A loud hiss filled the room, along with the delicious smell of frying meat. Moving the meat around so it browned evenly, he added the onion. While they were frying, he set up the rice cooker.

"I didn't know you cook, Onii-san." Ayase commented quietly, watching as he added rice and water. Kirino hummed, observing the meat with an unusual amount of interest.

"I don't do it often. I'm not that good, really," he rubbed his neck, smiling sheepishly. "I only know a few dishes."

If he had been alone, he probably wouldn't have cooked at all - he could be lazy like that. It was only because Kirino and Ayase were around that he bothered at all. He doubted they would be happy with convenience store food.

A few minutes later, he added the vegetables and then the sauce, mixing it around. He felt his mouth starting to water as a wonderful smell drifted around. Kirino hummed again, looking pleased. She then began setting the table with Ayase, without being asked. Kyousuke thought that things were going really well, though he was a little nervous at the way Ayase kept staring vacantly at the knife rack next to him. She could be really disturbing, that girl.

Soon enough, dinner was served.

Kyousuke seated himself in his usual seat, while Kirino and Ayase sat across from him.

"Itadakimasu!" they said together before digging in. Kyousuke grinned, tasting the flavour of his own cooking for the first time in what felt like forever. He didn't want to seem cocky or anything, but he felt he did a pretty damn good job for a novice.

Ayase took a delicate bite, chewing it slowly with a thoughtful look on her face and unwittingly looking amazingly adorable. Swallowing, she beamed at Kyousuke. "Onii-san, this is really good!"

"Ah - thank you," he replied, embarrassed at her earnest look, surprised. Praising yourself was one thing, receiving it from someone else was another.

Kirino nodded slowly, swallowing her mouthful and fiddling with her bowl. "This is better than I thought it would be. Y-You should cook more."

Kyousuke froze, his chopsticks hovering over his bowl. He felt his face heat up.

...my little sister and my little sister's friend can't be this cute!

...what the hell was going on?

He was about to continue eating when a sudden bright flash drew his attention to the window, before an ear splitting crack made him flinch in panic. He ducked instinctively, jaw clenched as the windows rattled in their frames. Kirino shrieked in surprise, nearly toppling from her chair in fright while Ayase went rigid in alarm, eyes wide with shock. Their ears were ringing as the thunder continued to rumble, not as loud but not quietly either. Several seconds went by before it finally died out, to be replaced by the sound of driving rain.

"Argh," Kyousuke rubbed his abused ears. It must have close to produce such an ear splitting boom. "That was loud."

Kirino steadied herself but looked nervous, like a rabbit about to bolt. It was then that Kyousuke remembered that Kirino hated thunderstorms. Some might say that it was silly for a girl her age to be scared of such things, but everyone had their own fears. He could still recall the time the power went out when she was still in the bath and they had both been left home alone. Ayase was less upset but was clearly alarmed. Her eyes were still wide and it made her look slightly stressed. Did Ayase hate thunderstorms as well?

"Are you okay?" he asked his sister.

She frowned harshly, glaring at him in anger. She lashed out in her fear and embarrassment. No one liked being frightened. "W-What are you talking about, baka? A bit of thunder doesn't w-worry me. Tch - don't even talk t-to me."

Then why is your voice shaking, baka?

That's what he wanted to ask but just shrugged instead and went back to his meal, eating a little faster. A second bout of thunder cracked overhead after a brief flash, though this time Kyousuke was ready for it and didn't so much as bat an eyelash. Kirino went stiff as a board, her teeth clenched around the end of her chopsticks. Ayase was hunched over a little, subdued.

"Ayase-san?" he asked. He waited until she was looking at him before continuing. "Are you okay?"

"Ah - I'm fine, Onii-san. It was just a surprise." she waved him off, though it wasn't very convincing.

Oh well - it's not like I can do anything about it, anyway.

They finished their dinner in silence, punctuated by loud claps of thunder. By the end of it, Kirino looked to be at the end of her tether. She was liable to lash out at him if he didn't choose his words carefully, though he was saved from saying anything at all when Ayase offered to do the dishes, roping Kirino into helping. Smiling gratefully, Kyousuke announced that he was taking a shower and left the clean up to them.

As the shower spray lanced against his back, he sighed in relief. He had been looking forward to this all day. He just stood there for several minutes, enjoying the lukewarm water as it trailed down his body and ignoring the continuing claps of thunder overhead. Content, he started washing himself quickly. It wasn't until he got to his hair that he realised his shampoo was empty. Inspecting the bottles on display, he grunted - they were all Kirino's. One of the bottles even had a little Meruru on the label. It was probably for kids.

"This looks familiar..."

Shrugging, he lathered some into his hair. Sickly sweet strawberry assaulted his senses but he powered on, massaging it into his scalp and then rinsing it out.

"What's with strawberry today?"

Normally, he would soak in the bath after his shower but was happy enough without it. Invigorated by finally being clean after such a sticky day, he turned off the taps and began drying himself. Task complete, he dressed in a pair of shorts and an old shirt that he slept in. Towel around his neck, he stepped out of the bathroom after dropping his dirty clothes in the washing hamper next to the door. He was drying his hair when-

"Ah~!"

"Oh!"

Kyousuke paused, bowing.

"You can use the shower now, Ayase-san. Sorry for taking so long."

Ayase was standing by the stairs, looking a little vacant at his sudden appearance. Shaking her head, she nodded happily and bounded upstairs, no doubt in search of her bag. Just as she vanished from sight, Kirino exited the now dark living room, face puffed in anger.

"Stupid lightning," she muttered, stomping towards the stairs. "Stupid thunder, stupid storm."

"Hey Kirino,"

"Huh?"

She turned, surprised.

"Are you okay?"

"I already told you-"

"I know," he interrupted hastily. "But are you really?"

Indecision was written all over her face. Finally, she sighed. "I hate storms."

"Yeah. If you need anything..." he said, purposely leaving it hanging.

She took a step back. "Auh! You really are a siscon, aren't you? You think this is your chance, huh?"

Kyousuke palmed his face. "Why can't I just be concerned for my imouto, hm? I don't have to have ulterior motives."

"That sounds like something a siscon would say to get their imouto to lower their guard, doesn't it? You are really going full throttle tonight, aren't you? First you cook for me and now this."

He sighed. "I really don't understand what goes through that head of yours, sometimes."

"Hah - that makes two of us."

He watched her leave before shaking his head. She really was something else. Ayase appeared a moment later, carrying her bag and a towel. Kyousuke stepped away from the bathroom door to let her through, ready to go upstairs and waste some more time on the internet - because really, what else was there to do?

"Onii-san?"

He stopped at the foot of the stairs, glancing back.

"Yeah?"

"Why aren't you like this more often?"

The question caught him by surprise. "What do you mean?"

"You haven't sexually harassed me all day," she said seriously, causing his head to drop. "And you haven't lied, either. Not once."

Lied?

He floundered, unsure what he should say.

"I like it when you are your regular kind self."

What?

He watched silently as she entered the bathroom and closed the door. Kyousuke remained standing there for about a minute afterwards, utterly bemused. What the hell had that been about?

"Those two," he whispered to himself, finally moving up the stairs and entering his bedroom, "are really doing my head in tonight."

Once more losing himself in the internet, he was able to distance himself from the storm raging outside, even as it picked up in intensity. He was halfway through watching some absurd video about dressing up your dog - who the hell did these kinds of things, anyway? - when the loudest crack of thunder yet tore him from his weird entertainment and back into reality, his windows rattling violently. His light gave no warning at all before going out, plunging his room into semi-darkness. The light from the laptop screen ensured it wasn't a total blackout, but the internet was now gone.

"Crap!" he swore, as he heard his sister yelp in the next room over. Reaching into his desk drawer, he pulled out a small torch. Powering down the laptop, he flicked on the torch and made his way out into the hallway. Looking at his sister's door, he was unsurprised to find Kirino peeking out, clearly terrified.

"Kirino?" Ayase called from inside her bedroom, barely audible over the howling wind. From what Kyousuke could tell, she sounded worried.

"I'll be right back," he told his sister, before carefully navigating the staircase. Once on the first floor, he made sure everything was closed and locked tight before checking the switchboard. Opening it up, he flicked it up and down, but it was no good. He didn't really expect anything to happen but it was worth a shot. He could already feel the temperature in the house changing, with the aircon out of commission.

"Aniki," Kyousuke nearly had a stroke as Kirino pulled on his sleeve, scaring him half to death. Wait, what did she say?

"Looks like the power is going to be out for awhile," he said, shining the torch on his sister. She had snuck down the stairs after him. "Sorry, but I can't do anything about it."

He did one more quick sweep of the lower floor and then ushered Kirino upstairs. Ayase was waiting for them, standing by his bedroom door. It wasn't until the girls were standing side by side that he realised what they were wearing. They had obviously changed for bed after showering, for they were dressed in identical nightgowns. The sheer material looked to ripple under the light of the torch, clinging to their slender frames in an undeniably enticing manner. They were rather short, not even making it down to mid-thigh, showing copious amounts of smooth, unblemished skin, while the thin straps revealed their bare shoulders. Kyousuke had no doubt that if viewed from a certain angle, you would be able to see cleavage.

What. The. Fuck.

He swallowed, his mouth feeling oddly dry. Kyousuke knew that these types of nightgowns were considered fashionable and were probably extremely comfortable to sleep in, but they were seriously dangerous!

"Onii-san," Ayase said quietly, jolting him from his thoughts. He had been staring at her chest and prayed to every God imaginable that she had not noticed him doing so. Even worse, he had also looked at Kirino. "Um - c-could we stay in your room tonight?"

Kyousuke thought he heard glass break somewhere. Probably deep within his psyche.

What?!

"What?" he said stupidly.

"This storm is a bit rough," she continued, not noticing that she had probably just completely broke his brain. "And - I mean, don't get the wrong idea," she quickly said, waving at him with one of her hands as if warding off an evil spirit. "It's just - we would feel a lot safer... with you... around..."

What?!

Kyousuke stared at them. He waited for Kirino to object - to say something that would indicate that Ayase was just pulling his leg, having a laugh at his expense - but she remained shockingly silent. Any moment now... any moment, aliens were going to abduct him. They already had his sister and her friend. These two girls were impostors. They were going to take him next.

"Ah - Onii-san?"

"Er - sure." he answered without thinking.

What did I just agree too?

Was it just Kyousuke's imagination or did they both look oddly happy? He remained motionless as Kirino took the torch, explaining that they were going to get their blankets and the spare futons. Then they were gone and he was left to ponder in the dark what had just occurred.

He was still standing there when they returned with their things. He followed obediently as they entered his room, still dazed at the sudden turn of events. Trying to regain some semblance of control, he shuffled over to the windows and shut the curtains as the two young girls set up their futons. It would shield them from the flashes of lightning, if nothing else.

Okay, calm down. Calm down. Kyousuke, calm down!

Breathing heavily through his nose, he crawled into his bed. He tried not to look. He really did - but Kirino was bending over, adjusting her pillows and her nightgown was riding up. He had the horrible urge to reach out and run her fingers against her inner thighs. It only got worse when Ayase joined her, though she was facing him and he got a glorious glimpse of her brea-

Oh god.

Kyousuke glared at the ceiling.

Kirino and Ayase finished arranging their beds and finally settled down, wiggling under their blankets. The torch turned off with a click.

Well, this isn't awkward at all...

Kirino and Ayase were whispering but he wasn't able to make out what they were saying. Girl talk? He wasn't sure he wanted to know. He reached out for his alarm clock and pressed the button on top, illuminating the time. Luckily it ran on battery.

9:49 PM

Even with the pounding rain and howling wind, with the rumbling thunder and general outlandish situation he was currently experiencing with his sister and her friend staying in his room, Kyousuke was somehow able to nod off. The only reason he knew this was because something bumping him in the side very clearly woke him up sometime later.

Blinking blearily, Kyousuke listened as the storm continued to rage. He felt a little sluggish, his rest having been interrupted before he could truly settle in. How long had he been asleep? It felt like only a few minutes had past.

Attempting to sit up, he froze. His arms were trapped and something was pressed against his chest, a pleasant weight that awoke something primal inside him. Shifting, he felt smooth, incredibly soft skin against his legs - entwined with his legs. Small puffs of breath ghosted across his shirt and when he craned his neck down, he could smell toothpaste. The lack of light made it impossible for him to see clearly, but-

I must be dreaming.

Snuggled against him on each side were two beautiful girls.

"What..." he whispered hoarsely.

One of the girls shifted. He wasn't sure who it was until, "Mm, shut up, Aniki. Just go to sleep."

Kirino.

The atmosphere was stifling. The humidity was still high and having two girls pressed against him only made it warmer. They had removed his blanket at some point and the three of them were only covered by a thin sheet, which was beginning to dampen with their sweat. His bed was a single, so they were practically draped all over him.

"But what-"

"You should listen to your sister, Onii-san," Ayase muttered, pressing her face into the crook of his neck. Her long, manicured nails felt good as her hand moved down his body before slipping under his shirt, scraping against his bare stomach in the most pleasurable of ways. Kirino's hand followed, snaking down and under, and only stopping when it lay above his heart. Their tangled legs tightened on his own and the result was young, budding flesh pressed against him on all sides. "Don't get the wrong idea. W-We are just taking comfort in your presence."
