"Oh, I forgot to show you." I reached into the back pocket of my jeans. "Look what I bought on my way to work today." I held a collar in front of Itachi's face. I watched as he stared at it, questions written all over his face.

"You bought it for yourself to wear?" He asked finally, his eyebrows furrowed. He grabbed it out of my hand, studying it up close. "It doesn't really look like your style, but I'm sure it looks great on you." He sat up on the bed and gestured to me to get closer. "I want to see you with it." I leaned towards him. He carefully put the collar around my neck while making sure none of my hair would get caught in it.

"So? What do you think?" I asked, feeling myself blush. "Do you like it?"

"I wasn't sure if I would," he admitted. "But it strangely suits you, I like it." He put one of his fingers underneath the collar, pulling me closer to him by it. I could feel myself getting red as he parted my lips with his tongue, not wasting any more time before he pushed me back down on the bed under him. His hair was falling down into his face and I couldn't help but run my fingers through the lengths instinctively. When I realised what I was doing, I quickly moved my hand to his back. Was I starting to pick up on his mannerisms?

While Itachi made love to me that night before we both fell asleep, his arm wrapped around my waist, I couldn't stop thinking about him. I knew from the start that getting involved with him in any way would be a bad idea, but somehow, it didn't occur to me up until now, how much of an impact his actions were having on me. I wasn't sure if Itachi noticed anything out of the ordinary or not. Did he notice that my heart wasn't fully with it, not because I was losing feelings for him, but because I was doing something that would hurt him if he found out? How was I supposed to live with the fact that I was hurting him again?

When I got into the office the next day, the collar tightened by Itachi's hands around my neck, I was already dreading what was going to happen next. To my surprise, Shisui was late again, and I felt glad that he wasn't there yet. It meant I could avoid him for a while longer, but it also meant that my mind had free time to wonder about what was going to come next. I began to dislike who I was becoming, because even though I was painfully aware I was doing something wrong, I enjoyed it to an extent. I could feel my heart skip a beat when the main door began to open and he walked inside, holding two cups in his hands again. Immediately, as his eyes lingered on my neck, the corners of his lips curled into a smile. He closed the door and locked it, which was unusual enough to make me watch cautiously as  he walked towards my desk, handing me one of the cups.

"So I take it that you did as I told you?" He took the lid off of his drink and took a sip. "What did he say?" He wore a self-pleased expression as he spoke in a low voice.

"He liked it."

"Oh?" He walked around the table and then sat on top of it. "Did you get anything out of it?" He leaned towards me. "What did you let him do to you?"

"That's none of your business." I said, feeling flushed.

"What my pet gets into is my business, Sasuke." He lifted my head up. "Or did you already forget what happened yesterday?"

"How could I forget," I pushed his hand away. "You were being unfair." There was no way I could forget how he called me into his office yesterday, just a couple of hours before we were supposed to be done for the day. He sat me down on the sofa, kneeling in front of me. He didn't look vulnerable in his position at all, as he was looking up at me.

Did I really make you feel so good that you needed Itachi to help you? I could hear his words as clear as if he was repeating them again. Were my kisses really enough to make you practically beg for it like a dog? You were being so loud I could hear you in the living room. I could see the arrogant look in his eyes as he presented me with the collar. Itachi told me about your idea of me getting an animal. Why won't you become my pet? I tried to argue against him, but when he was tired of me refusing and instead started to make out with me, soon enough my reasoning melted under the heat of his body against mine. I want you to tell him you got the collar for yourself. Wear it every day. If you don't, our little secret might accidentally spill out, you wouldn't want that now, would you?

"How was I being unfair?" He laughed.

"You practically blackmailed me."

"You know you're having fun with this as much as I am." He put his hand into my hair, grabbing a handful. He made me stand up from my chair, pulling me closer. "The sooner you admit it to yourself, the sooner you will be able to enjoy it even more."

"How long do you want to keep this up?" I asked, looking away from him. "I don't want to do keep doing this behind Itachi's back."

"Would you rather let him know you've been doing this behind his back then?"

"Why are you doing this?" I tilted my head backwards, letting out a sigh.

"I told you, it has been way too long since I was with someone. And it's either you, or him." I felt his lips brush against the lower part of my neck. "I'm alright with either, it's entirely your choice."

"Why can't you just let us be?"

"Because messing you up is too much fun, you can't expect me to just stop when I can see how much you're actually loving it." He got off the desk and while holding my hand, he led me into his office. "Now, since you had fun because of me on Itachi's birthday and then because of the collar I gave you," he stroked my head. "I think it's only fair you return the favour?"
