The Sweetest Love In the World

The following day after their parents had returned from their slave labor at the black company, Keiki sat in his still-empty classroom, reporting yesterday’s incidents to Shouma, who was seated in front of him.

“Ahaha. That’s a bummer.”

“You can say that again.”

Because of the unexpected and unwanted visitors, their lovey-dovey time was put on hold. Right when he had mustered up his courage to climb the steps to adulthood with his girlfriend, all of it was ruined.

“In the end, we played games together.”

“You’re pretty close, huh?”

“Guess so.”

Their parents might hardly ever be home, but they weren’t on bad terms or anything. Even this morning, they had an enjoyable family breakfast. Mother and daughter got really into the cooking, dishing out meal after meal which now was making Keiki feel kinda bloated, but it was still enjoyable despite that.

“Oh yeah, I’ve never met your parents before, now that you mention it.”

“They’re hardly ever home. Since both of their workplaces are so far away, they rent rooms near them.”

“Since when?”

“Since I started middle school. Around that time, they started showing up at home less and less.”

“Must have been rough.”

“I’m used to it by now. And I was never lonely, thanks to Mizuha.”

With both of their parents working full-time, it was just those two siblings living together in a fairly large home. Their family lifestyle might be a bit abnormal, but Keiki and Mizuha were allowed to live freely with their parents’ allowance, so he was thankful to them despite it all.

“But I’m glad everything worked out with Mizuha-chan. Seems like the birthday surprise was a success.”

“I was a bit worried when we got caught in that snowstorm, though.”

The day before yesterday, March 3rd, they had visited a hot spring district. Because of an out-of-season snowstorm all the trains had stopped, and they were desperately searching for an inn to stay at, but they luckily managed to find shelter at a charming place, and he succeeded in giving her the ring, so the results were satisfactory despite everything.

“I don’t think I need to ask, but how did she react?”

“She was so happy that I felt even more embarrassed. She’s been grinning at the ring ever since.”

“Glad to hear it.”

“Well, she takes it off for school, though.”

Their school regulations were fairly modern and open-minded, so she probably wouldn’t be reprimanded, but an engagement ring would only cause a ruckus at school. Not to mention that there are faint remains of a particular rumor still lingering around. It wasn’t serious enough to really care about it, but laying low for the time being would surely be their wisest choice.

“I wonder why our parents suddenly came home like that.”

“Because they got time off work, no?”

“That’s what they said, but…”

Something didn’t sit right with Keiki. They suddenly came home at a very random time, yet were unable to make it back for New Year’s, so Keiki couldn’t help feeling dubious about their explanation.

“…Well, whatever.”

He knew how nonchalant his parents could be. Them coming home randomly now without thinking anything of it was plenty normal enough.

“More importantly, because they’re home, Mizuha and I can’t have any fun at all. Remembering how clingy she was during the trip makes it hurt even more now…”

“I never thought you’d end up this infatuated with love, my dear Keiki.”

“It’s Mizuha’s fault for being so cute.”

Ever since Keiki came to terms with his feelings for her, they’d been growing non-stop.

Even yesterday, Mizuha was so cute…

He was reminded of the situation from the previous night. Sharing their feelings to each other on the living room sofa, kissing each other, with her expression filled with endless love. Realizing that he was the only person who could see such an expression made him feel even more excited.

The way I’m pent up is just hell…

Putting things on hold like that is painful in a lot of ways. To put it a lot more bluntly, Keiki was so horny it was tough to handle. Mizuha most likely felt the same way. Even on their way to school today, she awkwardly fidgeted the whole time.

I’m dying over here, but flirting with Mizuha is not an option with our parents home.

Keiki sadly wasn’t confident enough to fully express his feelings with the possibility of his parents seeing it. He would have to wait until it was just the two of them at home again. According to them, they’d be leaving in two to three days, which would be either tomorrow or the day after tomorrow, but the time seemed much longer than usual.

“Ah, it’s Mao-chan.”

Keiki raised his head when Shouma said that. He spotted Nanjou Mao right as she waltzed into the classroom. She was wearing a coat above her uniform, a student bag was on her shoulder, and her reddish-brown side-tail swayed left and right as she walked towards them.

“Morning. What are you two talking about?”

“Keiki’s parents came home yesterday.”

“It seems like they both took a vacation together.”

“Hmmm…? Your dad, huh?” Nanjou-san made an awfully wicked expression.

She put one finger on her lower jaw, muttering to herself.

“…Father and son action?”

“You really don’t have to have your damned BL fantasies every single time you hear about someone!”

For a second, Keiki envisioned the end of the world.

“By the way, do you happen to have a picture of your dear father?”

“Sure don’t. I wouldn’t show you even if I had one.”

“Tsk. I was hoping to use it for reference…”

And that was the exact reason Keiki didn’t want to show her. After everything he had been through, Keiki knew very well that such a request was only for her to have more BL material. As a result of this conversation, though, the hellish ‘Dad x Keeki’ couple remained in his head for a while.

“And Mao almost got more BL material.”

On the way home, Keiki explained this incident to Mizuha, who let out a snicker.

“A picture would have been fine, no?”

“Hell no. Why would I want my BL debut with Dad?”

“So you’re fine if it’s with Shouma-kun?”

Not in the slightest. Keiki had simply given up in that regard.

“I’m looking forward to Mao-chan’s new release, you know?”

“Oh, yeah. You read it too, huh?”

She had already opened the door to this accursed new world. Starting with Sayuki, then Yuika, and now Mizuha, all girls in the calligraphy club had become fans of Minami Mao-sensei’s doujinshi works.

“So, Nii-san, why are you looking away from me like that?”

“Don’t worry about it.”

Keiki felt too awkward to directly look at Mizuha. Things may have calmed down compared to the previous night, but that didn’t mean all the embarrassment had vanished entirely. Indeed, all of those feelings had come rushing up once more, and the lingering sensation of her breasts under his fingers made him feel all ticklish. Passion was burning inside of him.

“You’re so cute that I can’t look at you directly.”

“I don’t get it.”

“I’m not lying, though.”

“Well… thanks…”

See? So adorable. Keiki’s younger sister making a bashful reaction was too adorable. All his desires that had previously been sealed away by Mao’s BL plan came welling back up again.

“Mizuha…”

“Hm?”

“Can I kiss you?”

“Huh?!” Mizuha stopped in her tracks and her gaze shot towards Keiki.

Her face was as red as a tomato.

“Did I say something weird?”

“Ah, no…It was just a bit unexpected…You don’t really say that sort of stuff often.”

“Huh, really?”

“Yeah. Usually it comes from me.”

“Ahhhh…”

Thinking back on it, the entire time that Mizuha was trying to win Keiki over, he never asked for anything himself. In fact, the one who invited him the day prior was Mizuha. The change in Keiki’s feelings made this sort of change possible.

“I just like you so much, I don’t think I can hold back.”

“Eh… Ehhh?” Mizuha fidgeted awkwardly.

She probably was a bit bewildered by this sudden expression of affection, but she immediately grinned and seemed satisfied.

“So a kiss should be fine, right?” Keiki asked.

“I’m happy, but we can’t.”

“We can’t?”

“We can’t.”

Mizuha flat-out rejected him.

“I mean, we’re outside,” Mizuha said.

“That is true, I guess.”

They were walking down a sidewalk by the street. Lots of other people were out and about, and there were cars passing by. Kissing each other in such a public place would just be absurd, especially if somebody who knew saw them.

“But with our parents at home…”

Keiki wanted to partake in his one chance to enjoy some lovey-dovey action at home, but their parents had gotten in the way. Even if they locked themselves up in a room, he wouldn’t be surprised to find his parents eavesdropping on them. Keiki once more wished that their parents would return to work quickly.

“I hope they’ll leave soon, to be honest.”

“I’m pretty happy.”

“So you don’t want to be lovey-dovey with me, Mizuha?”

“Don’t start sulking now. We rarely get the chance to spend time with them.”

“You’re not wrong, but I can’t flirt with you as much as I want now.” Keiki said. “I can’t hug you, I can’t kiss you, and even the continuation from yesterday…”

“The continuation from yesterday…?”

Mizuha must have caught on to what Keiki was implying. She blushed strongly.

“…Nii-san is so lewd.”

“I won’t deny that.”

“So you won’t deny it.”

“I am quite the healthy high school boy, yes.”

“Sometimes you talk really weird, Nii-san.”

But since they’re siblings, she stopped worrying about that ages ago. As their relationship progressed, Keiki had to stop holding back, and he became invincible. Rather, it was a miracle that he never felt any urges while living with a cute girl like Mizuha.

“…But I feel the same way.”

“Huh? …Mizuha?”

Suddenly, Mizuha moved right next to Keiki. She stretched upwards and gently pressed her lips against Keiki’s cheek.

“Only until our parents leave, okay? Put up with this for now.”

“………”

Met with this surprise attack as strong as a thousand suns, Keiki could only look at Mizuha’s bashful smile in a daze. She walked ahead, and Keiki touched his cheek.

“Mizuha… that had the completely opposite effect…”

Keiki felt like he had gotten a single slice of high-class steak after having been starved for days. Naturally, it wasn’t nearly enough to satisfy Keiki, and he was now even more hungry for flirting.

That night, after eating dinner, Keiki went to take a bath. Being the first person to enjoy the bath was always something exciting. Keiki wasn’t as much of a clean freak as his sister, but he also didn’t dislike taking baths. After taking off his clothes with some cheerful humming, he started taking a hot shower, as was his routine. He was enjoying his brief taste of happiness when—

“Let me join you, Son.”

The arrival of his own father Makoto completely ruined any kind of bliss he had been indulging in.

“Um, Dad?! Why are you coming in without asking me?!”

“What’s the problem? We’re both men.”

“That’s exactly why I don’t want this!”

Needless to say, Keiki’s father was naked. Without needing any further explanation, he was completely, utterly butt-naked. Even if they were related by blood, Keiki couldn’t stand the sight of a man in his fourties showing up during his bath. However, as much as Keiki tried to protest, his father simply stood tall in front of him, not even trying to hide anything.

“I was thinking of seeing for myself how much my son has grown. A naked get-together between family members shouldn’t hurt every once in a while, right? A bath would be the perfect chance for a private conversation, no?”

“Taking a bath with my own dad at my age would be nothing short of torture…”

“Don’t be like that. And while we’re at it, wash my back, won’t you?”

“No thank you.”

“Then I shall wash your back instead.”

“Blegh…”

As a son, Keiki seemed to have no right to deny it. He saw no other choice but to bear it, so he sat down on a bath chair (with both of them wearing towels, of course). With a sponge and an abundant amount of soap on it, Makoto started scrubbing his son’s back.

“How’s this, Keiki? Does it feel good?”

“It’s not bad, but I would have preferred it if Mizuha washed my back instead.”

“Huuuuh? Are you not satisfied with your father’s service?”

“If anything, I see no reason why I would be satisfied in the first place.”

Why was he being forced to take a bath with his own father again? For a split second, Keiki was reminded of Mao’s ‘Father and son action’ comment earlier today, but he did his best to banish those wicked thoughts. Thanks to her, his mind completely trended towards BL.

“…Hey, Keiki.”

“What is it now?”

“Take care of Mizuha.”

“Huh?” Keiki almost turned around when he heard this, only to remember at the last second that his own father was sitting behind him practically naked, so he instead just responded orally. “What do you mean by that?”

“I’m sure I said this before, but I think of her as my real daughter. But at the same time, she is still the precious daughter of your mother’s friend.”

“Yeah, you adopted her after all.”

Ten years ago, Mizuha lost her real parents during an accident, so Makoto and Touko took her in as foster parents.

“When we decided to adopt her, we both swore to her parents that we would take care of her until the very end. That is why I have the duty of making sure she is happy. Originally, I hadn’t planned on just letting her go off and get married.”

“And yet, you sure gave me permission quickly when I called you about it…”

“We didn’t agree to your relationship with nonchalant feelings, you know. We simply thought that we could leave her to you, since you’ve always cared for her.”

“I see…”

“It’s not that big of a deal, really. Just one thing. Take good care of her from now on. To make up for her parents’ share, for our share, you’d better stay with her.”

“Dad…”

Keiki could tell that this father was very serious about this simply from his tone. And then a certain doubt he had came back to mind, and he voiced it.

“Did you come back just to say that?”

“Ah, you noticed?”

“I mean, your timing of coming home was far too abrupt and random.”

“I know I’m letting you live laissez-faire style, but I was worried after hearing about that rumor at your school.”

Keiki was confused why they both got time off at the same time, but as it turns out they had probably been so adamant about taking this time off because they were concerned.

“Well, it seems like I didn’t have to worry in the first place. Whenever Mizuha’s with you, she looks the happiest. She’s even more clingy than before, so as her father, I feel lonely…”

“That last half was just your selfish greed as a father speaking…”

Makoto sounded like a sore loser. If Keiki turned around now, he would probably see his father making a defeated expression.

“So, that rumor has been resolved, right?”

“Thanks to your help, yeah. The fact that our parents accepted it helped a lot.”

“You weren’t related by blood from the very beginning, so you can be as open about it as you want.”

“We’ll do just that, yeah.”

Thanks to the student council and newspaper club, that heavy atmosphere directed towards them at school had vanished. Right now, the worst he got were blessings from his classmates along the lines of ‘Explode, damn siscon’.

“You’re a lucky guy, Keiki. Nowadays, it’s hard to find a girl who’s so devoted and skilled at housework, you know?”

“I’m well aware.”

Mizuha is pretty, kind, and popular with all the guys at school. She’s good enough of a catch that she almost seems wasted on such an average guy like Keiki.

“Don’t make her cry, you hear me?”

“I know. I can’t even think of a life without Mizuha anymore. I won’t ever make her feel lonely anymore, and I will do everything I can to make her happy.”

Keiki swore to always be together with her. He wouldn’t let go of the hand she held, and he wouldn’t let her be alone ever again. He was confident that he would not lose against anyone when it came to these feelings.

“I see. That’s a relief.”

“You sure seem happy, Dad.”

“The son and daughter I treasure get to be happy, so as a parent, I couldn’t be happier.”

“…Yeah.”

With the sudden serious tone shift of the conversation, Keiki was unsure how to react. He felt genuinely embarrassed about this whole ordeal.

“I’m actually relieved, you know? It’s not been that long since you entered high school, but since you showed no signs of ever getting a girlfriend, I was scared you’d live your life all alone.”

“Piss off, Dad.”

Keiki had lived his life without ever experiencing anything resembling a romance, but he had still received chocolate every single year.

“So how did you end up getting this close with Mizuha?”

“Huh?”

“Not too long ago, we were on the phone and you found out that you two aren’t related, and now you’ve ended up like this. Come on, spill the beans.”

“Why are you making it sound like we’re on a school trip?”

“Don’t be embarrassed now. I’m not leaving until you tell me.”

“What an awful threat that is…” Keiki felt truly annoyed.

Talking with his old man out of all people about the beginning of his love would be much worse torture than anything else he had previously experienced. But even so—

“…Well, fine.”

In the end, it’s been a while since they got to spend time together, so going along like this shouldn’t hurt.

“I’ll wash your back now, Dad.”

After that, he answered all sorts of Makoto’s questions, and was forced to even listen to how his parents’ love started. They talked for a long time, but never ran out of things to say. Until the very minute they left the bathroom, their conversation continued.

*

Around the time the men of the Kiryuu Family were enjoying a naked get-together, Mizuha and Touko had finished cleaning up the dishes, and were now seated around the dining table, enjoying some hot chocolate.

“They sure are taking their time,” Mizuha said.

“You’re right. I’m sure they have a lot to talk about.”

“A lot to talk about?”

“How cute you are, how much of an angel you are, how every family needs a Mizuha-chan. That sort of stuff.”

“I highly doubt that.” Mizuha let out a snicker.

As was evident, Toukoa was somewhat of a jokester at times.

“Though I have to say I’m surprised that you’ve gotten even better at cooking.”

“It’s all because of you teaching me, Mom.”

“You’ve long passed me at this point. I feel like I need to get you to teach me now.”

Until Keiki and Mizuha started middle school, their parents had decided to stay with them, living together as a family. Mizuha had learned the basics of her household skills back then from her mother.

“What do you like about Keiki-chan, Mizuha-chan?”

“Huh? Where did that come from?”

“I was watching you all day yesterday. Your ‘I love you’ aura has been seeping out of every core of your body, so I was just curious.”

“What kind of aura is that supposed to be?”

“It’s the truth, though. You looked like a maiden in love.”

“It’s that obvious, huh?”

Mizuha evidently wasn’t aware of the aura she was giving off. Honestly speaking, ever since they started dating, and she didn’t have to hold back her feelings for him anymore, she had completely lost control.

“Even if you ask me that… How kind he is, how he spoils me all the time, and how he can work so hard for somebody else, I guess?”

“Hmmm? There are that many reasons, huh?”

“Urk…”

Her mother grinned at her, and Mizuha felt her face growing hot. Talking to her mother about the person she liked felt different than telling a friend about it.

“I’ll be your mother-in-law once you get married, huh?”

“You’re jumping the gun, Mom.”

“You think so?”

“We’re still in high school.”

“That’s only true right now. Soon you’ll graduate from high school, become university students, and then you’ll be proper adults in no time.”

“Is that how that works?”

“It sure does. You’ll be a grandma before you realize it.”

“Grandma…”

Mizuha couldn’t even imagine that, or anything about the future. On the most fundamental level, Mizuha simply wanted to be together with the person she liked. Marry him, have children, and build a happy family. That must be happiness.

“He’s a lucky guy for receiving this much affection from such a cutie.”

“I wonder?”

“I’m sure. Keiki-chan was also giving off that lovey-dovey aura. This is the first time I’ve seen him so infatuated with something.”

“He only started being conscious of me recently, though.”

“Really?”

“He forgot that we’re not related by blood, after all.”

“Ahhh, I see…” Touko let out an awkward comment.

She held the cup with both her hands, awkwardly averting her face as she confessed.

“The reason Keiki-chan had the wrong idea… might actually be me.”

“Huh? What do you mean?”

“He actually asked me about it before. Even though you were supposed to be siblings, he asked why your birthday was only five months apart. He was taught about it in class one day.”

“Yeah…”

“Back then, he thought that you were his genuine little sister, so I figured it would be fine to not tell him about you being adopted… In the end, I just said ‘It’s because I did my best to give birth to her quicker’…”

“So that’s why Nii-san never questioned it…”

Back when the identity of Cinderella had been revealed, and Mizuha brought up the contradiction in regards to their birthdays, Keiki let out a puzzling ‘Isn’t it because our parents worked really hard?’ answer. When a parent tells you something when you’re young, you end up believing it no matter how nonsensical it may be. And without having it pointed out, you don’t realize how wrong it was.

“Since I didn’t know about your feelings back then, I guess I just got in the way…”

“That’s not true.”

Touko raised her head in surprise and was greeted by Mizuha’s smile.

“I’m happy that you thought of me as your real daughter.”

“Mizuha-chan…”

In the end, she was the foster child of the Kiryuu Family. In regards to that, they never talked much about it. That showed her parents treated her as their own child, which was why Mizuha had never had any intention of blaming Touko for it. Not to mention that Keiki’s attitude most likely wouldn’t have changed either way. On the contrary, his affection for her hadn’t changed in the slightest even after being told that they were not related by blood. Him being this way is why she fell in love with him in the first place.

“Hey, Mom?”

“Hm?”

“Thanks.”

“Huh? For what?”

“You came home to watch over us, right? Because a lot happened at school.”

“Ah, you found us out?”

“It doesn’t make much sense for you to come home at such a time. Sorry that we forced you into this.”

“A parent would always be worried about their children.”

“Yeah… But I’m fine now.”

When the rumors went around, Mizuha certainly was hurt. She felt sad, guilty, and tried to keep distance from the person she liked. However, he cleared up all of this anxiety she had felt.

“Nii-san was really cool, you know. He did so much when those rumors went around. Although I was a bit surprised to hear about the engagement.”

Just how much did this save Mizuha? She turned all of these feelings inside of her chest into words.

“He took me out on a trip for my birthday, and he even gave me a ring as a present. I’m really, really happy.”

Happy to the point she could break out in tears any second.

“That’s why I want to make Nii-san happy now. I want him to feel glad that he chose me.”

She felt bottomless gratitude to her parents. Taking her in as she was all alone, treating her like their genuine daughter. Loving her endlessly so that she didn’t feel lonely. The gratitude she felt couldn’t be put into words, which was why she had to put them into her actions instead. Becoming happy with Keiki was the best way to show all of that to her parents.

“You’ve grown a lot in the short time I haven’t seen you.”

“Thanks to all of you caring for me.”

“I guess so. I think I don’t have to worry about you anymore.” Touko gave her a relieved smile.

That smile resembled someone else, making Mizuha happy.

“Mizuha-chan, how about we take a bath together once those two are done?”

“Sounds good.”

There were still so many more things to talk about. And Mizuha herself felt excited to decide which story to tell her mother next.

*

Early the following morning, when the stars had yet to even vanish from the dark sky, four people gathered at the entrance of the Kiryuu Household.

“All right, it’s time we return to our respective battlefields.” Touko sighed.

“Yup, another deathmatch awaits us, tehe~” Makoto made an awkward wink.

“Sorry, but that dark humor doesn’t really hit home for me.”

Met with such a depressing mood, Keiki couldn’t help but make a complicated face. Just as the contents of their conversation hinted at, it was time for their parents to return to their work. As this farewell was happening in the early morning, Keiki and Mizuha were still in their pajamas. To be specific, his little sister was wearing a warm and comfy-looking one-piece. In contrast, their parents were in full battle armor, wearing coats above their suits, their shoes put on properly like soldiers heading off to war.

“You could have at least stayed for breakfast.”

“I’m sorry, Mizuha, but there’s been some trouble at my company,” Makoto said with a wry smile.

“Same here. It seems like nothing really works out if I’m not there,” Touko nodded.

“Make sure to get proper rest, okay?” Mizuha looked a bit anxious.

“It’s fine. We got a short break now, and my Mizuha-chan energy has been recharged.” Touko said, embracing her daughter one last time.

Makoto watched this exchange and put his hand on the doorknob.

“Alright, you two, we’re going.”

“Make sure to get along while we’re not here, okay?”

“Yeah, you be careful out there, Mom, Dad.” Keiki smiled.

“Have a safe trip.”

Sent off by their children, the two left the house. They walked together halfway, then split up and departed towards their respective workplaces.

“The storm has finally passed, huh?”

Keiki’s comment just highlighted how noisy the house was with their parents home. Yet now it was unbelievably calm, and the house felt too big for just the two of them. Even so, thanks to the girl next to him, he didn’t feel lonely in the slightest.

“Now it’s just the two of us again, Mizuha.”

“You’re right.”

“It’s a bit early, but let’s prepare for school later.”

It was only around half past 6 am. Not exactly a time where they would have to rush, but also not early enough time for another nap. Keiki started to head back to his room, but certain circumstances didn’t allow him to do so. Namely, his little sister grabbed his hand in hers.

“Mizuha?”

“…Um, Nii-san?”

“Y-Yeah…?”

“Today… once we get home… the continuation from last time…”

Towards the end, her voice grew weaker, but the grip on his hand became stronger. Since her intent was so clear, and she was looking at him with dampened eyes, even Keiki wasn’t dense enough to miss what she was referring to.

“Mizuha…”

“……” Her face was as red as a tomato, showing her embarrassment without the need for words.

Keiki’s blood started to boil as he received all of this heat, and he remembered what had happened on the night of March 4th in the living room of this very house. Exchanging kisses, and the sensation of their feelings becoming one and the pleasure of doing so. Naturally, Keiki wished to continue the events of that night. Now that the nuisance of their parents was gone, and these two lovebirds were alone, they obviously were conscious of each other.

“I-I guess we should prepare for school…!”

“R-Right…!”

Even after they let go of each other’s hands, the oppressively sweet atmosphere would not go away. While imagining their soon-to-be future, the two of them found themselves unable to look each other in the eye.

Keiki could not focus on the classes at all. Because of the events of the morning, no formulae nor English grammar stayed in Keiki’s head for longer than two minutes. Even a single period felt like an entire day’s worth of classes. It must have been really suspicious to anyone watching him, as Keiki was warned several times by the teachers during the day, earning himself a glimmer of worry from Shouma and Mao, and even Yuika was dubious about Keiki’s behavior. Naturally, he took the day off from club activities.

After that, he sent Mizuha a message to meet up at the front entrance so that they could go home together. The same as they had headed to school, they barely exchanged any words now. They met eyes several times, but neither of them reacted much, and they just kept on walking. They were undoubtedly thinking about the same thing. Namely, what was about to happen the moment they got home. That thought alone filled both of them with anticipation but also uneasiness.

They went home directly with no detours, and right as they entered their home, locking the door behind them, Keiki took her to his room. They threw their bags to the side, took off their coats and blazers, and pulled the curtains closed. Inside the dimly-lit room, they sat down on the bed. Keiki wanted to confirm things one last time just to make sure, but that seemed to not be needed. Looking at Mizuha’s wet eyes, brimming with anticipation, Keiki found himself unable to hold back. He placed his hands on her shoulders and pressed his lips onto hers for a kiss.

It was a sweet and gentle kiss, but once he set on for a second one, it became a lot more passionate. As if to replicate the events of that night, they exchanged kiss after kiss. As if to regain what they had lost that evening, as if to convey their bottomless affection, with each kiss, they began to remove a piece of each other’s clothing. One layer was gone, then another, all the while they both held back their desire to just rip them off each other.

Soon enough, the floor was covered with scattered clothes, and finally the last layer of white underwear fell to the ground. Met with this overwhelmingly beautiful scene, Keiki swallowed his breath. The girl laying on the sheets in front of him was too alluring. Revealing everything she could, the girl’s cheeks were red in embarrassment, which only caused Keiki to feel more aroused, causing him to reach the limit of trying to act like a gentleman.

They called out each other’s names, and as their bodies overlapped, everything turned hazy. After the initial awkwardness, they both longed for each other even more, until Keiki could only see the girl in his eyes. With white skin drenched in sweat, a sweet scent filling the air, hot breathing hitting his neck, a high-pitched voice moaning into his ear, all of her acted as a serum to completely dull Keiki’s ability to reason. The girl he cared so deeply for accepted all of him. There was no greater joy than this feeling of being connected to the person you adore, with both body and mind.

—-Even after everything was done and their initial heat subsided, his precious feelings for her never fully cooled down.

By the time Keiki woke up, he was laying in his bed, facing upwards. How much time had passed since then? The faint light entering the room had already changed from the setting sun to a faint moonshine. When he turned his head sideways, he found his beloved girlfriend right next to him. She was using him as a hugging pillow, her cheek resting on his chest, her upper body relaxed. Although they were covered by the blanket, that was only true for their lower body, so Keiki could clearly see Mizuha’s bare shoulders. It seemed like Mizuha had been watching her older brother for a while, because her eyes were fixated on him. And once their eyes met, they both let out a snicker.

“This is a bit embarrassing, huh?”

“You’re right.”

“Also, that was… amazing.”

“Yeah, that it was.”

Even though quite some time passed since the act, the aftertaste had yet to fully fade. Since this was their first experience, they were not used to it at all, and things didn’t work out perfectly. In fact, Keiki wasn’t sure if he even was going at the right speed for Mizuha. But there was one thing he was certain about.

“I’m really happy that I got to do it with you, Mizuha.”

“…Yeah.” Mizuha nodded and drew her body even closer.

Keiki gently placed her palm on her cheek, and she happily narrowed her eyes.

“Hey, Nii-san, can I ask you something?”

“Hm?”

“I’ve been meaning to ask this for a while now. When the rumors went around, you kissed me at school, right?”

“Yeah, sure did.”

As the rumors of the two siblings dating went around, the relationship between the two of them temporarily became awkward and distant. The reason for this was that Mizuha had spotted Mao aggressively approaching Keiki in the classroom. After that, Mizuha had a misunderstanding about his relationship with Mao, and she ran off crying, which was why Keiki saw no other option to calm her down except to kiss her. It was all messy back at the time, but it seemed like Mizuha still remembered it.

“Why did you kiss me back then?”

“Well…”

Keiki reminisced for a moment. At the very end, he managed to figure out the reason behind the emotions he felt, but the reason for his actions made him hesitant to tell Mizuha, as it was awfully embarrassing.

“Do I… really have to say it?”

“When you put it that way, it only makes me more curious.”

“Right…”

Naturally she’d be curious about the reason behind Keiki’s actions as it ended in a kiss of all things. Hiding it wouldn’t do him any good either way, he figured, so he went ahead and told her.

“Well, you know. That kiss was born from jealousy.”

“Jealousy?”

“Back then, you were avoiding me because of the rumors going around at school, yeah?”

“Yeah…”

“Since I know the reason behind it now, it doesn’t matter much anymore, but back then, I was afraid. Despite avoiding me, I saw you suddenly getting along with another guy, so that made me feel jealous.”

There may have been different circumstances back then, but Mizuha still rejected her brother’s confession and avoided him. And yet, she suddenly started getting along with Rintarou, which certainly was no laughing matter for Keiki.

“And yet, there was a misunderstanding between me and Nanjou, so when I saw you cry and realized that you still liked me… and because of how cute you are… I didn’t want anybody else to have you, so…”

Back at the time, Keiki’s kiss was his own attempt at stopping the girl’s tears. But that wasn’t all of it, because he also fell in love with her even more. These two desires blended together into the act of kissing her.

“So that’s why…” Mizuha muttered, sitting up straight on the bed, covering her face with a pillow, “I didn’t expect Nii-san to be this attached… It’s so embarrassing…”

“I really don’t get what makes you feel embarrassed and what doesn’t…”

She was totally fine showing off her panties, and yet she had such a pure side that didn’t match it at all. However, the sight of his bashful little sister was too adorable for Keiki to handle. He waited for the moment Mizuha showed her face and kissed her again. It was a simple and sweet kiss with just their lips pressed against each other, but once that was done, they laughed.

Just that miniscule amount of skinship was enough to fill their hearts with joy. However, the only organ filled was the heart after all. Keiki’s stomach grumbled in an attempt to inform him of his primitive instincts other than reproduction.

“Sorry about that…” Keiki apologized for utterly ruining the mood, blushing beet red.

However, Mizuha just let out another snicker.

“That reminds me, we didn’t even eat anything yet. Maybe I should make something light?”

“This late? Are you sure?”

“Omurice would be easy.”

“Omurice… I can make that.”

“Huh? You will?”

“I made my own food when you were staying at Koharu-senpai’s place… Well, I don’t think it’ll be that great, so maybe you should make it after all…”

“No…” Mizuha shook her head. “I’d like to eat Nii-san’s omurice.”

As it was a request from his adorable girlfriend, Keiki naturally couldn’t decline. Haste makes waste, as they say, so Keiki quickly took a shower, and headed to the kitchen, preparing the dinner while Mizuha took a bath. The menu consisted of simple omurice, chicken rice wrapped up in a half-cooked egg. In the end, Keiki wasn’t totally happy with the cooking he pulled off, but after Mizuha had gotten a taste, she smiled with a gentle ‘Delicious’.

In fact, it was at least better than the one Keiki had made before. It was surely thanks to the fact that Keiki made it for the person he cherished. Now he understood why Mizuha could always put all of her heart into her cooking. Making food for the person he cared for was fun, and he felt happy that she liked it. With that in mind, he realized that in both love and cooking, your feelings for the other person were the best possible spice.

The following morning, Keiki and Mizuha finished their preparations as always and headed to school. After putting on their indoor shoes, they were reunited again, and talked about this and that while heading up the stairs. They had planned on taking their time while walking, and yet they reached their destination all too quickly, arriving at their respective classrooms.

“Alright, Nii-san, I’ll see you later.”

“Yeah…”

“…Nii-san?”

As expected, Mizuha realized that there was something off with Keiki.

“What’s wrong?”

“Well… I’m not sure if I should say this, but…”

“Yeah…?”

“Because we’ve been together all day yesterday, I just… don’t want to separate here.”

“Huh…?” Mizuha’s eyes opened wide.

Even Keiki himself never expected it to turn out this way. However, after coming home from school until this very moment, they had always been together. Getting up together, eating breakfast together, going to school together… And because they were inseparable for basically the last 24 hours, the time where they couldn’t be together felt even more depressing, making it harder to split up here. Naturally, Keiki felt pathetic because of it, but it was the truth.

“Seriously, what am I even saying…? We’ll see each other right after classes anyway.”

“Nii-san…”

“Hm?”

“Come with me.”

“Huh? …Mizuha?”

Mizuha suddenly took his hand, pulling him along to a particular classroom building, more specifically to an open space. It was a small area away from the noise of the other students, and once they were in the shadows of a large pillar standing in the hallway, Mizuha let go of Keiki’s hand.

“Turn around for a second.”

“Sure…”

Keiki did as he was told, when he heard the sound of Mizuha’s bag falling to the ground, as well as faint rustling of clothes.

I wonder what she’s up to now?

Keiki naturally was curious, but he decided to keep quiet and wait just like that. After a few seconds passed, he heard a confident “Okay, you can turn around” from Mizuha. Receiving permission, Keiki turned around again, and faced the girl—

“Here you go.”

Along with these words, she offered Keiki a pair of water-blue panties. Since her actions were so natural, Keiki accepted the panties with his own two hands, and closely inspected them.

“Um, Mizuha-san… What am I looking at here?”

“My panties.”

“I mean, yeah, I figured as much…”

There was no reason to even doubt it for a second. Keiki of all people would know.

“But they still feel warm?”

“Because I was wearing them up until now.”

“You took them off here?! What if somebody saw you?!”

“It’s fine. Nobody’s around.”

“That’s not the problem here.”

The problem was in the greater scheme of things such as morals or common sense.

“It’s a bit embarrassing even for me, but I was so happy to hear how lonely you were, so this is a special service for you, Nii-san. While we can’t be together, I want you to treat these panties like they were me.”

“Are you telling me to keep these for the whole day?!”

“Ah, I have to get to my classroom or I’ll be late. You’d better hurry as well, Nii-san.”

“Wait, Mizuha-san?!”

Keiki stood still in awe, panties in hand, as Mizuha walked away with quick steps. After a few seconds of feeling the warmth from the panties, Keiki muttered to himself in confusion.

“What am I supposed to do about this…?”

Keiki knew that this was an act of kindness from Mizuha. However, panties at school would benefit nobody. And even so, Keiki couldn’t hold back a snicker.

“Mizuha’s face was so red…”

It was just a deduction, but maybe this entire thing was just Mizuha trying to hide her embarrassment. Because of what had happened the day prior, Mizuha might just be excited in her own way. Once again, Keiki realized that he had chosen quite the pervert as a girlfriend, but since he understood that this was her way of showing affection, he couldn’t help seeing such an abnormal approach as adorable. Even her face when handing him the panties was absolutely adorable.

“I can’t believe I’m grinning at my sister’s panties… I’m quite the pervert myself.”

A brocon little sister who loves her older brother so much she gave him her panties, and a siscon older brother who tightly grasped them. They might just be the perfect match; a perverted couple. But even so, Keiki couldn’t allow his little sister to go full commando at school.

“I’d better catch her later to put them back on.”

It was his duty as an older brother to protect his sister’s dignity. While praying that nothing bad would happen with her skirt in the meantime, he stuffed the panties in his bag and headed back to his classroom.
