Itachi's POV

Once I got Eita's to his room, I tended to his wounds. But I didn't have to do much since most of his wounds had been healed by the Tailed Beast living inside him. "Lie down, Eita. You might have a fever." I said. 

I gently pushed down on his shoulders so he'd lie down until Eita grabbed my wrist. "Give it to me... Give me pain, Master. I want it badly." He said, desperately. I stared at Eita, trying to figure something out. Could Hidan be right? Was Eita really a masochist, or is he just messing with me?

"Eita, you can drop the act now." I said, sternly. "Act?" He repeated.  "I don't understand what you mean, Master."

'Okay, so it's not an act. He probably really is a masochist. But how did this happen? When did he start being a masochist?' I thought. I noticed Eita's eye was red and not purple. I've seen it turn red before when we were having sex.

I thought my mind was playing tricks on me, but it was real. It seems that whenever Eita becomes like this, his eye turns red. So, how do I get him to snap out of it? Do I have to give him what he wants?

While I was thinking, I noticed Eita was taking off his shirt. "Eita, hold still." I instructed. I needed to figure something out. I leaned down and gently bit his neck. He moaned rather loudly, so I quickly covered his mouth to muffle his sounds.

I licked over the bruise that was forming, then sat up. Eita's face was still red and he had tears in his eyes. He took my hand off his mouth and licked my palm. "Don't stop, Master. I like it. Please, continue." He begged. 

'First, I hear Hidan's his master, and now he's calling me his master. A small turn of events.' I thought. Eita took my finger in his mouth and began to suck on it. Looks like I really do have to give him what he wants or else he'll never snap out of it.

I took my finger out of his mouth and pinned Eita to the bed before biting down on his shoulder. He let out another lustful moan, making me cover his mouth once again. I felt him breathing heavily against my palm as I licked over the bite mark.

I kissed and licked my way down to his torso, then licked his nipple. Eita moaned against my hand, then tugged at the ends of my shirt, trying to take it off. I followed with his request and removed the item of clothing from my body.

Before I could continue, Eita quickly pinned me down to the bed. "I... I want to make Master feel good." He said. I smirked at him. "Then, by all means, make me feel good." I said. "Yes, Master." He replied. He undid my pants, then pulled down my boxers.

He licked the tip of my member before taking it into his mouth. I moaned softly as I tangled my fingers in his hair. Eita sucked my member harder and faster, earning a groan from me as he continued. "Eita...!" I warned.

I came into his mouth while covering my own to prevent me from moaning so loudly. I panted a bit before looking at Eita. He slowly removed his mouth from my member and I noticed some cum dripping from the sides of his mouth.

Eita gulped down the cum that was in his mouth, then looked at me with a smirk. "Thank you for the delicious meal, Master. I hope to have it again soon." He said. 

His turned purple, then passed out on my torso. "Eita." I said, quickly sitting up to check on him. He slept soundly against me, making me sigh. "Sleep tight, Eita." I whispered before gently kissing his head. 

Eita's POV

"Mm..." I slowly opened my eyes as I started to wake up. I blinked a couple times before sitting up. "What...? Where... am I?" I mumbled to myself. I looked around and noticed I was in my room. But how? Wasn't I in Hidan's room?

I blinked when I remembered Hidan was kicking my ass, then drove knives into my hands. I quickly looked at my palms and saw that they were healed, making me sigh in relief. "Finally awake?"

I jumped startled and saw Itachi examining the wood carvings on my desk. "How are you feeling?" He asked. "Uh... okay. Wait, what are you doing in my room? Shouldn't you be resting? What about your wounds?" I asked. 

"I'm feeling better, so you don't have to worry. But I'm more concerned about you at the moment."

"Me? Why be concerned about me?"

"You honestly don't remember?"

"Remember what?"

"Okay... Tell me the last thing you remember."

"Um... I pissed off Hidan, he dragged me into his room, tortured me for a bit, and then... That's it. I don't remember anything else past that. Wait... Do you know what happened?"

"Go take a shower and I'll tell you." 

I didn't argue and did what he said. I took a quick shower, then put on some clothes. "So, what happened after Hidan kicked my ass?" I asked as I dried my hair.

"I'm not going to sugarcoat this, so I'll get straight to the point. You turned into a masochist after Hidan made a few cuts on your body." Itachi said, straightforwardly. "Come again?" I asked, not sure if I was hearing that right. 

"I'm not joking about this. Your eye turns red when you feel a certain amount of pain, and that turns into a side that's different. A side that makes you beg for more pain. A masochist," I stared at him as he continued.

"And it's not just this time. I've seen it happen before when we were together. Do you know what could've caused this?"

"Possibly." I said, hesitantly, as I gazed at the ground. "Tell me." Itachi ordered. "I don't want to. Not right now." I said as I shook my head. "Eita, tell me how this happened. I want to help you." He said, grabbing ahold of my shoulders. 

"I said, I don't wanna talk about it! Leave me alone!" I yelled. I shoved him away and ran out of the base. "Hey, Eita! Where ya going?" Deidara called. But I was already out of the base. I ran into the woods until I was sure I was out of sight. 

I crouched down and pressed my hands to my face. "I'm disgusting. How could I... Why did I have to turn out like this?" I whispered as I held back my sobs.

Itachi's POV

"You should give him a break, you know?"

I turned my head, spotting a girl with pale skin, black hair, and dark eyes standing there. She wore what looked like a girl's school uniform in the color of black. She looked at me and her eyes glowed blue for a second.

"Who are you?" I asked. "My name's Inari. I'm the Nine-Tails' Opposite. Or sister, I should say. I'm also the Tailed Beast living inside Eita." She answered. "Why do you choose to show yourself now?" I asked.

"Because I need to talk to you about Eita. He's been through a lot over the years, so you should give him a break. " Inari said.

"Do you know what caused him to become a masochist?"

Inari didn't reply for a moment until she sighed. "I do know. But don't tell Eita I told you, got it?" She asked. "I understand." I replied. Inari snapped her fingers and we were inside an image. "Where are we?" I asked. 

"Inside Eita's memories." She answered. Inari walked forward and showed me a room. There, I saw Eita as a child strapped down to a table with Orochimaru next to him and a bunch of different tools. 

"Eita wasn't always a masochist. He just turned out like that because of Orochimaru. After he kidnapped Eita, he began experimenting on him in hopes to get me to come out. But I didn't budge that easily. In the end, it changed Eita. Ruined him," Inari explained. 

"Eita begged for Orochimaru to stop. For days. For weeks. For months. He pleaded him to find another way instead of this torture. But there wasn't one. Not for him... Not for me... Not for us. I couldn't risk what would happen if Orochimaru successfully managed to lure me out, so I stayed hidden inside Eita. Every day, I listened to Eita's cries, how he begged for mercy or for Orochimaru to just kill him and end his suffering there. Each cry made my heart chip until it was completely shattered. Finally, Eita got used to the pain and torture, and started enduring it all. At one point, he started begging Orochimaru for more pain, and that bastard happily obliged. I refused to hear anymore of it, so I finally worked up the courage to reveal myself. From there, I took over Eita's body and we escaped Orochimaru together."

The image of Orochimaru and Eita faded as Inari and I were back in the Akatsuki hideout. "So, now you know of how Eita became like this. How he suffered... How he endured... You mustn't tell anyone of this. Eita would be too embarrassed. He's already ashamed of his past, so there's no need to make his life any more difficult." Inari said. 

"I won't tell a soul. You have my word," I said. "You and Eita are linked, right? Do you know where he is right now?"

"Somewhere deep in the woods. But I suggest you leave him be for a while." Inari said before vanishing. 

After she left, I went looking for Eita.
