Leni, still not understanding what her sister was getting at, nodded slightly, indicating that at least she had understood something.

"I understand what you mean, but I don't see how a simple kiss can be so problematic. Isn't it just a gesture, after all?"

Leni asked, even more confused as she stared at her sister.

Lisa let out a small sigh as she tried to control her anger and also the jealousy she was feeling at the moment.

"Leni, the problem here isn't the kiss itself."

Lisa said, as she tried to explain to her sister the seriousness of the matter, but in a way that she could understand, something that was difficult enough in itself.

"And even if it was a gesture of affection, you can't forget that he’s, our brother. And kissing him in itself is something we shouldn't do, and that shouldn't be so hard to understand."

After hearing what her sister had said, Leni inflated her cheeks slightly, indicating that she was a little annoyed by the whole situation.

"I understand, but it's not that big a deal either. There's no need to get angry..."

Leni said, while looking at her sister with a calm countenance, which ended up making Lisa even angrier. However, before Lisa had a chance to say anything, Leni interrupted her, continuing what she was saying.

"The only thing I can't understand is what all the fuss is about over a simple kiss."

Lisa was already losing it with her older sister, but she calmed down and once again tried to explain.

"I told you, it's not the kiss itself that's the problem, it's who you kissed."

Leni frowned slightly, trying to understand Lisa's point of view.

"Ah, now I get it. You're saying that the problem isn't the kiss itself, but the person I ended up giving it to, right?"

Lisa nodded, relieved that Leni finally seemed to understand.

"Yes, exactly that. The problem lies with the person you kissed."

After Lisa said those words, Leni pondered for a moment. But after reflecting on her sister's words, she finally managed to come up with a solution to the whole problem.

This narrative has been unlawfully taken from Royal Road. If you see it on Amazon, please report it.

"Then it's simple to solve it: I just have to take back the kiss I gave him."

Said Leni, with a small, almost imperceptible smile on her lips, which only Lisa could see because she was close by.

(I already knew that Leni's intellect was a bit retarded, but that's too much. And I don't know why, but I think she's taking advantage of this whole situation and, for some reason, it's making me a little angry).

Lisa thought, as she looked at her sister with an indifferent expression, trying to forget the scene she had seen a few minutes ago.

After saying those words, Leni advanced again towards her brother, who was still paralyzed in the same place he had been before receiving the first kiss. However, before he could recover from that first shock, Leni goes over and, without any shame in her face, ends up giving him another kiss, which ends up leaving her two sisters incredulous once again at the lack of common sense and sense of the second eldest daughter of the family.

However, even though Leni was doing it out of habit, there was no way she was going to deny that she didn't like it if she was asked. She was aware that it was wrong and immoral... but somehow, she couldn't explain it; it all felt so good.

"See, I just had to take the kiss I'd given him back, it was no big deal. You made all this fuss for nothing."

Leni commented, with a slight smile on her face.

Listening to Leni's words, Lisa still looked incredulous, not quite able to believe what she had just heard. Just as she was about to say something, Lori, who until then had been quiet because of her shock, spoke up for the first time.

"For God's sake, Leni! Have you lost your mind? He's literally our brother. Can't you see that this is wrong?"

Lori asked, slightly altered, almost shouting, as she stared at her sister with a sign of disapproval.

Lincoln, who until that moment had still been in shock and paralyzed by the kiss Leni had given him, came out of his trance when he heard his sister almost shouting.

"But what did I do wrong this time? I only did what Liza told me to do."

Leni replied, raising her voice as she raised her arms, pretending not to understand her sister's argument, but at the same time, she really didn't understand anything that was going on.

Lori, realizing that her sister was trying to play the victim, ended up getting even angrier, which made her lose her temper a little and raise her voice even higher.

"Don't play dumb now, Leni! You know very well that what you did was wrong."

Lincoln, who had already come out of his trance, realized that the sisters' 'little fight' could end up becoming something more serious and decided to intervene.

"Let's stop this before you two ends up falling out. And to be honest, who cares?"

After Lincoln's words, the three started talking at the same time, as if in unison.

"What do you mean?"

With those simple words, Lincoln not only managed to get his sisters to shut up and be quiet, but he also managed to get them to stop fighting. But that silence didn't last long, as Lori, now with an even more confused expression on her face, began to stare at him without understanding anything he was saying.

"What do you mean 'who cares, Lincoln? Have you lost your mind like Leni? It's not hard to understand, it's simple: she's your sister, and you know it's wrong."

Lori commented, a little disgusted by what she had just heard.

Lincoln, with all the calm in the world, responded to his older sister's comment with an indifferent expression, not really caring.

"It would be wrong if we were brothers, and since we're not, since I'm literally adopted, then just forget it."
