"Good night, everyone!"

"Good night, Sarashina-senpai."

Alisa flashed a tiny smile at Chisaki's final words to end another night for their group, as it was time for them to get some rest.

She even had a little response of her own, because she was in high spirits and it would be a good way to continue her way of making up for her past transgressions.

Everyone headed upstairs altogether and disappeared into their rooms at the same time, but Alisa didn't touch her bed yet.

The girl remained at the door, leaning back against it as she bore a conflicted look on her face.

"The anger and jealousy that I felt back then… the things that made me say such awful words and do heinous things…"

She winced upon remembering those three particular incidents that she caused; yelling at Yuki, slapping Ayano in the face, and injuring Masachika's ankle.

As much as she'd rather forget about them, they also served as reminders about what she had done and how unacceptable her actions were.

They were things that served as constant reminders in which these events must never happen again, under any circumstance.

"...they're gone now. I feel like a completely different person. And because of that, everyone accepted me again."

Several days have gone by ever since Alisa finally apologized to everyone, and things have gone well… for the most part. She began opening up to the others and even went out of her way to offer assistance to anyone who needed it.

"Everyone except for Masha and maybe Taniyama-san, I suppose. Although I don't even deserve their forgiveness, I have a chance to make things right."

Until now, her sister still remained distant and avoided any chance of having a conversation with her. Masachika had explained to her that Maria still needed time before she's willing to talk, but it didn't make things any less painful inside.

Sayaka was a different case. Despite her words about not holding feelings of pettiness, the bespectacled girl maintained a level of distrust towards Alisa, believing that the silver-haired girl got off too easily after everything she did.

It was nothing serious, but it could very well spiral into another problem for their group… even after resolving one not that long ago.

In fact, Taniyama's issue was noticeable enough in the others' eyes that Miyamae herself assured Alisa that she would talk to her friend about the whole thing.

But for the most part, things were back to normal once more… and it's all thanks to a certain boy who never gave up on her.

"And all of that… is because of Masachika-kun. Because of him… I'm not lonely anymore. I have someone by my side," she smiled to herself.

Alisa waited for at least half an hour before opening the door and poking her head out to see if there was anyone around.

After making sure that there was no one around anymore, the girl saw it as an opportunity to finally leave her room and meet up with a person very special to her.

"It's been a few days since the last time we spent the night together because he's been talking with Masha, but anyway…"

An eager look took over her features, which was accompanied by a beautiful smile on her face.

"...I'll be with Masachika-kun again for the night."

Alisa headed upstairs with a red face and her legs closed tight, her mind coming up with all sorts of scenarios at what could possibly happen tonight while she's with Masachika in his room…

She couldn't help it at this point, because it just so pleasurable and fulfilling every time he had his way with her body. Sex became a regular occurrence between them and she wouldn't change it for the world.

As she got closer to the door, some weird noises seemed to emanate from inside Masachika's room… giving off the impression that someone else was there other than him. It's quite hard to tell from where she is, actually…

"Ever since I began following Masachika-kun's orders… ever since he started training me, I've felt nothing but relief and happiness again. I don't feel miserable anymore."

However, Alisa was completely oblivious to these noises, as she was too distracted by the happy thoughts within her mind. Even when she was right in front of the door and knocked a few times to announce her presence, she still failed to notice them.

"That's why I can't fail him. Not again. I have to be of good use to him. I have to be a good pet to him! That's because…"

And as she opened the door—

"...Masachika-kun means everything to—"

—what greeted her was the sight of the individuals on the bed, naked as the day they were born, and in the midst of an intense lovemaking session.

One of them was no doubt Masachika himself, while the other person was someone whom Alisa would never expect to be here… in this place and in this situation.

"Huh…?" she mumbled.

Sitting at the edge of the bed, Masachika bore a satisfied smirk on his face as he watched his younger sister bounce up and down his crotch, impaling her over and over with his twitching rod.

Her sizable mounds bounced along with her movements, and Masachika's gaze were fairly glued to them. Yuki noticed this and smirked, throwing out her arms and wrapping them around his neck before pulling his head towards her breasts.

Masachika complied by licking and sucking on her sensitive nubs, earning several moans of bliss from his sister.

Yuki's noises of utter pleasure rang in Alya's ears like alarm clocks, snapping the half-Russian out of her trance as tears began forming in her eyes.

She had been invited by Masachika to visit him in his room, only to be met with a sight like this. Alya felt a pang of hurt and betrayal inside her chest, which she quickly denied in her mind.

No, there's no way Masachika would do such a thing… it's impossible… he wouldn't bed another woman that's not her…

"This… is just a dream, right…? I'm just having a dream…"

"Oh… there you are, Alya. I was wondering when you'd show up," Masachika acknowledged her presence at the door with a nod as he grabbed Yuki's hips and quickened the pace entirely.

"M-Masachika-kun, what… what is this…?" Alya stammered, her mind doing its best to try and make some sense out of this situation. "With… Y-Yuki-san… your… sister…"

As soon as the girl realized what she had just said, she felt the urge to throw up which caused her to clap her hand over her mouth. It took her a few moments to register this whole event in her mind, and all she could feel was repulse and confusion.

"Why… W-Why are you doing this kind of thing… with your sister…?"

Unfortunately for Alya, she would never receive her answer because Masachika would suddenly appear before her out of nowhere, smiling as if nothing was wrong.

"Recently, I've been thinking of how much more interesting it would be if there were more of us in this arrangement we have. Three's a crowd, after all."

"...huh?"

"Why are you still standing there?" he frowned in confusion before pulling her inside rather forcefully. "Get in here and strip already!"

"W-Wait, Masa—"

Alya wouldn't even get the chance to say anything as Masachika pulled her towards the bed where Yuki was, before pushing her on top of the soft foam. She was too confounded to do anything, but was perfectly aware of what was happening.

"I'll show you that you have no power over me here, Alya. I don't belong to you. You belong to me."

Masachika watched with an impassive look as Yuki pounced on the vulnerable Alya, immediately stripping her of her clothes and leaving her in the same state of undress as the siblings.

"Y-Yuki-san, please wait—"

Tears forming in her eyes, Alya attempted to push the other girl off of her, but Yuki pinned her wrists above her head and stopped the girl from doing anything.

"Shhh… nothing bad's gonna happen to you, Alya-san~"

Yuki giggled while whispering those words into her ear, before giving it a long and sensual lick. Alya bit her lip to keep herself from making any more noises, only for that feeling to stop all of a sudden.

Thinking that it was finally over, Alya opened her eyes and tried to move, only to see Masachika in Yuki's position instead. His sister moved to the spot atop her head, where Yuki kept her arms pinned an unable to do anything.

"M-Masachika—" she tried to speak, only for Yuki to cover her mouth and prevent her from doing so.

"I'll make you understand that you're in the same place as Yuki… right under me."

The young man gripped her hips and buried himself into her, drawing out a loud moan from her, unable to keep herself contained anymore.

In the end, Alya was completely at the mercy of the two siblings, who both found a sense of enjoyment at seeing her in this state of pleasure.

"...and so, that sums up what I want to do. In order for me to help you and your sister, I need you and Yuki to get along and work with each other whenever I need you to. I ask you not to be jealous of her just because she was before you. We've been doing the same thing, anyway."

At the mention of her name, Yuki giggled softly and did a 'teehee' pose, taking pride and satisfaction in that particular fact.

"Now, you can say what you want about my relationship with her, but understand that it won't change a thing. We already crossed the forbidden line as siblings, and we don't really plan on stopping anytime soon."

Masachika finished his explanation right as he was also done putting on a fresh set of sleepwear, before turning around to face the bed where Alya was.

The silver-haired girl was curled up in a fetal position on the bed, panting heavily out of exhaustion. She was completely spent after their act of debauchery, especially with Yuki somehow being involved this time around.

"Do you have anything to say, Alya?"

"...if it means being with Masachika-kun… and making amends with Masha…" Alya whispered, a tearful smile etched across her face as she looked at him. "...I'm okay with that."

"Good."

"Looks like we managed to successfully convince her, Onii-chan~" Yuki looked at her brother and smiled at their shared accomplishment.

Masachika nodded in agreement. He was honestly expecting a bit of resistance from Alisa because of her jealousy towards Yuki at first. It's also surprising that she had nothing to say about the taboo relationship between him and his sister!

Perhaps he had trained her enough to just accept this new arrangement without complaint.

That or the girl realized that she didn't really have a choice in this matter. Whichever works.

"I… do have a question, Masachika-kun…" Alisa spoke up again, fighting against her exhaustion to be able to sit upright.

"What's that?"

"Does this mean… you'll do this with Masha as well?" she asked, feeling curious about what Masachika was truly planning on doing.

"What? No," he denied almost immediately. "I wouldn't do this to your sister, of course. I just want to help her, that's all. She's not only important to you, but to me as well. I want to help you two and that'll never change."

"I see…" she muttered. Alisa had no reason not to believe him and honestly, Masachika looked and sounded genuine with his intentions.

Furthermore, it feels reassuring to hear him state that he wished to help her and sister.

"If I may suggest something, Onii-chan…" Yuki raised her hand to get her brother's attention, causing him to turn towards her. "I don't think you should focus on Masha-senpai just yet."

"What are you talking about, little sister?" he frowned at her suggestion, as it reminded him of a certain girl whom he's been at odds with one too many times. "You're saying we should just leave her be?"

"Not necessarily," she shook her head. "You said it yourself, Onii-chan. All this time, Masha-senpai has been forcing herself to talk with Alya-san, and has been unsuccessful every time. Even though she wants to, she couldn't bring herself to hold a proper conversation with her younger sister."

Alisa lowered her head sadly, as she was once again reminded of her mistakes… especially because of how it affected her older sister.

"Don't you think that by doing this plan, you're essentially doing the same thing as she did? Forcing her to do something she's not ready to do?"

"I didn't even think about that. Damn it, I was too focused on helping her!" Masachika clicked his tongue in annoyance.

"Then what do you suggest we do, Yuki-san? We can't just leave my sister on her own. I have to make things right, no matter what."

"Patience, patience, my dear Alya-san~" Yuki smirked, positioning herself behind the half-Russian in mere seconds.

"W-What are you—?!" Her eyes widened at how quick Yuki was, before releasing a high-pitched squeal when the other girl began squeezing her breasts from behind. "Hya~!"

Yuki grinned at Alisa's reaction, while Masachika stared at the two with a deadpan expression.

Something tells him that his sister wanted to do this all along…

"I didn't say Onii-chan should ignore Masha-senpai entirely. I'm only saying that he can deal with something else for the moment," she clarified. "We'll still be helping Masha-senpai if we do this. What better way to help her than by giving her the space she needs to compose herself?"

"Please… n-no more…" Alya pleaded, and Yuki was actually kind enough to give her what she wanted this time.

"What do you expect me to do while that happens, then?" he frowned in confusion.

"You can still be there for Masha-senpai when she needs you. Talk to her, do things for her, and listen to her when she's saying something. Masha-senpai doesn't seem to have any problem with you, Onii-chan."

"Fine, that makes sense… but what do you think about this, Al—"

"As long as Masachika-kun can help my sister… I'm fine with it," Alya panted while recovering from the other girl's actions just now. "It doesn't have to happen as soon as possible. I don't like it, but Yuki-san is right… we shouldn't force her into this. If Masha needs time to herself, then I'm willing to wait until she's ready."

"All right," he sighed in defeat, fully conceding to Yuki's suggestion.

"I'm glad you chose to hear me out, Onii-chan~" she chuckled. "You and Alya-san have no reason to worry at all. Masha-senpai will be just fine. I'll even be willing to keep an eye on her if you want."

He raised his hand to stop her. "Hold on just a second. You said I should focus on something else instead of Masha-san right now, but what exactly were you talking about, Yuki? What could possibly be more important than her?"

"Well… I was talking about Ayano," Yuki grinned.

"You've gotta be kidding me," he groaned. "I had a feeling that Yuki had an ulterior motive, but I never thought she'd bring Ayano into this."

"You sound angry, Onii-chan. Did I say something wrong?" she asked innocently.

"Why are you trying to involve her in this? Ayano has nothing to do with this whole thing, you dumbass."

"My dear Onii-chan… you can't even begin to think about how much involved Ayano actually is! For starters, she's here with us on this island. She's in the same situation as the rest of us."

"What is that supposed to mean?"

"Onii-chan, Ayano may be good at hiding her feelings from everyone else, but she's in the same boat as us. She's just as worried about what could happen to us and if she wasn't trying to 'fulfill her duty', then we'd see Ayano in total distress."

"Really? Because I have a good feeling that this is just another one of your elaborate schemes to fuck around with me," he remarked sarcastically.

"I talked to her earlier, and I've confirmed that she is interested in you. That's all we need," she pumped her fist in the air victoriously. "Now let's come up with a plan on how we bring her into this, Onii-chan!"

"Stop right there. You're acting as if I'm even cool with this whole thing, which I'm not. I have no reason and no desire to do this with Ayano, so your idea can shove it."

She shrugged, "It's my idea to push Ayano into this, that's true… but what if she wanted it? Are you really going to reject her, Masachika-kun?"

"You're trying to get me to say yes, and it's not going to work. Stop trying to bring up Ayano, or do you want me to beat it into your head?"

"Okay, I'm shutting up for now…" Yuki sweat-dropped at his intense reaction. "Just remember this, Onii-chan. No matter how much she denies it, Ayano is just like the rest of us, a human being who desires companionship and social contact."

Deciding that he didn't want to hear anything more from her, Masachika turned his attention towards Alisa instead, beckoning her to come towards him so he could dress her in one of his shirts at least.

"Would you rather we leave Ayano alone to take care of herself when the time comes, even though she has always been there to help us in any way she can?"

However, Yuki continued to speak regardless and while he wouldn't admit it, her final words would ring true in his mind as a grim reminder of sorts.

"...are you going to wait until something bad happens to her before you do something, just like with Alya-san and myself?"
