(Kaito's POV)
"Sit." I told the three of them, gesturing at the table in the middle of the hotel room, "Now. I won't say it again."
We were back inside after I subdued the three of them; I knew they were going to try and cause a ruckus.
Naoya smacked her lips, "Fine...." She said, glaring at me, "I won't let this slide."
"That's enough of you." I said as the twins walked over to the table, "We're going to discuss this like fucking adults. All of us. I am getting tired of this."
Maki and Mai sat down reluctantly, Mai glaring at me as her eyes twitched.
Naoya and I sat down in front of them, the tension in the air was clear.
"Let's start with this." I said, looking at the two of them, "Naoya and I have this sort of relationship. She wants me to have sex with women while she watches, it is what we do. It is what keeps our relationship and marriage healthy. We keep it to ourselves and we don't involve others against their wills. That is all there is to it."
"Such a sick thing to do." Mai scoffed, "Maki, you knew of this?"
"Yea." Maki nodded, "Just recently."
"She caught Kaito fucking the maid in front of me." Naoya said, "But Maki-chan is a good girl, she kept her mouth shut."
"Naoya." I warned, "Enough."
"Hmph." Naoya said, "I'm only saying the truth."
"And what? You let Naoya get fucked in front of you? You're a cuck?" Mai asked
"No." I said, "Absolutely not."
"Nobody but my Kaito can penetrate me." Naoya said with a scowl, "Only his cock is worthy of me. Now, whether or not I want to kiss and indulge in women while he fucks them, that's something else. We both dominate them and-"
"They don't need to know all of that." I said
"You got that right." Maki muttered
"My point is that this is what we do." I said, "And I would appreciate it if you keep it to yourselves. You may not agree with it, but there is nothing you could do about it."
"Who knew you could be such a perverted creep." Mai said, giving me a nasty look, "You're unbelievable."
Maki looked at me, "Enough of this, Kaito." She said, "I already know this much. I have something to talk to you about!"
"Very well." I said, "What is it?"
She pointed at me with an angry scowl, "Why the fuck didn't you tell us about the Binding Vow?!"
"What?" I asked
"Binding Vow?" Mai looked at her with surprise, "What are you talking about?"
"Father is the one who scarred you, was he not? He cut you!" Maki said
"Ugh, don't mention that." Naoya said, "I wanted to kill him so badly for scarring my Kaito."
Mai looked at me, "That ugly scar...." She said, "Father did that to you?! And you let it happen! Everyone in Jujutsu High says that you are the strongest of the Zenin Clan, even compared to Naobito! How can you let Ogi do that to you?! What's wrong with you? Are you that weak-willed and spineless that-"
"He couldn't do anything about it, Mai!" Maki said, "He was in a Binding Vow with father!"
"Oh boy." Naoya said with a sigh, "She knows. I suppose your mother told her."
I felt my face hardened as I looked at Maki, "You were not supposed to know that." I said, "Why did Mother speak?"
"So you don't deny it?" Maki asked, "You were in a binding vow with him?!"
"I was." I said seriously, "So long as I kept training to the point I would become a Grade 1 Sorcerer strong enough to contend with Special Grades, Ogi would not lay a finger on the two of you. He would not abuse you like he did to me. In exchange for that, I would not fight back."
Mai widened her eyes, "What....?"
"So every blow you took from him...." Maki said, her eyes twitching in anger, "Y-You couldn't do anything about it? All because of the Vow?!"
I nodded, "That's right?"
"Why?" Maki asked, slamming her hands on the table, "Why would you do that?"
"I couldn't stand it." I said seriously
"Stand what?" Mai asked, her voice was soft
"I couldn't stand the thought of my sisters enduring the abuse that he would inflict on me." I said, "So I placed the Vow upon us. And that kept him from doing anything to you."
"Nobody asked you to do that!" Maki exclaimed, "You....Kaito, you-"
"Nobody needs to tell me to protect my sisters!" I cut her off, "My blood, my family! M-My.....my everything...."
I clutched my pants, my arms trembling slightly as Maki looked at me with surprise.
"Kaito-kun...." Naoya said
"The two of you were not the ideal sorcerers, Maki." I continued, "What do you think would have happened to you if I didn't do anything? Ogi would have put you through hell, that's what. I couldn't stand the idea of you two suffering because of me. Every single mishap the two of you made, you would have ended up being compared to me, the Blessed. The clan shunned you already, but this would have made it worse."
Maki looked down, "But that..." She said, "That is.....Kaito, why didn't you tell us anything? Do you think of us as weak?!"
"The last thing I wanted was to add more burden to the two of you." I said, "Listen, that was my cho-"
"FUCK OFF!!!!" Mai snapped, standing up and flipping the table over
"Oh boy." Naoya muttered
Mai was panting heavily, "YOU'RE FULL OF SHIT!!!" She said, an enraged look on her face, "All of these years!! You were under a Binding Vow?! All of those beatings that you took in front of us, all of the abuse that Ogi put you through!! It was all because you were under a vow?! No! No!!"
"Mai...." Maki said
Mai kept panting, her entire body trembling shaking slightly, "You didn't fight back.....you put yourself through all of that....!! For what?!" She continued, "For us?! Y-You...you sacrificed all of that for us?! F-Fuck you, Kaito!! All of those moments!! Those cold stares! Telling us to go to our room, all because you wanted to train?! It was all a bunch of bullshit!!"
I slowly stood up, "Mai....."
"NO!!!" Mai exclaimed, "I refuse to believe it!! I would rather you be a cold-hearted bastard who doesn't care about us! I....No!!!"
"Kaito-kun doesn't hate either of you." Naoya spoke up, "He loves you. I mean this with my heart, Mai-chan. He did this for his sisters, his baby sisters who he adores with all his heart."
"You're a piece of shit, Kaito...." Mai looked at me, completely enraged, "I fucking hate you...Y-you...."
"Mai." I said, "Calm down."
"I didn't want you to protect us!!!" Mai snapped, "I just wanted my brother!! I wanted my brother to love me! T-To be my brother!! I hate you! W-Why are you like this?!"
I reached for her hand, "Mai." I said, "Don't be like-"
She slapped my cheek, "Fuck off!!" Tears formed in her eyes, "I hate you! I fucking hate you!"
I pulled her in towards me, "Mai...."
"I hate you....I hate you....." She began to tremble as I embraced her, "I fucking hate you, Kaito....I fucking hate you....! Don't touch me! You fucking creep.....!! I...fuck....I hate you so much...."
As she began to sob, I hugged her firmly, not letting go as she dug her face into my chest.
"I'm sorry." I said, "I did it for the two of you. Please forgive me."
"I hate you....I...." Mai continued, her voice was shaking
"Why didn't you tell us?" Maki asked, "We're your sisters, Kaito.....we....."
"I don't know." I said simply, feeling Mai's arms wrapping slowly around my waist
"Fuck you, Kaito...." She sobbed, "I hate you. I hate that I love you...."
I sighed, gently patting her head, "My sweet Mai..." I said,
"I'm sorry for this."
