Psychology says that the one thing we can be sure about is that we are the ones thinking, I'm reading this in my head, just like you are, and we can be sure about it, anything else we can't know, is love real? We'll never have an answer, is hating someone really that bad? We will never be sure about it. But psych aside I know one thing for sure, I'm in trouble.

It all started a few weeks ago. He said it was only a work thing. But I know him, and Tony never works for real. I knew I should have been worried with the fact that Tony seemed to be pouring his love into this secret research. But the fact that JARVIS seemed to approve this secret calmed me a bit.

I just wish I knew what that smile of his was directed at every time I entered the room, it seemed hypnotizing and I knew it wasn't porn, during all the time I've been with Tony, dating or not, he never needed it, he lived porn before and now he, himself, said that it wasn't needed, because he loves me; then why was I so worried about that smirk of his?

It could have been a normal tuesday for me, but I was dating a billionaire, and he liked giving presents. It wouldn't be a bad habit, if it wasn't for the messages that were always behind it. The necklace was him giving his heart to me, or was that his arc? Arc was heart, necklace was trust.

I shook my head and focussed on the open box before me. The word 'Clothing' wouldn't be the first I'd use to describe it. Maybe 'Skimpy' would make to top 3. I shook my head and reached for my phone, it only took two rings for him to answer.

"What the fuck, Tony?" I quizzed the minute he greeted me.

"I see you got your present." He replied softly and I knew he was smirking, dammit.

"What does it mean?" I enquired.

"Do you know anything about being a sub, Pepper?" He murmured in a rough voice that made my knees turn to mush, however it was the question that pushed me to the chair.

"Yeah." I murmured carefully, admitting knowledge in certain areas has made me get in horrible situations during my time with Tony Stark.

"How much?" He tried to see if I was lying.

"I've been one." I admitted quietly, I wondered if JARVIS was recording this.

"Play or lifestyle?" He questioned and I knew he was getting jealous of the person that had done that with me.

"Play." I muttered and I felt a rush of warmth between my legs, thank god no one could see me.

"I want to try lifestyle." I heard his voice say and I jerked.

"No." I answered.

"Why?" He mumbled and I could tell he was hurt, or working on something else and not paying attention.

"Because you'd be my dom." I replied quickly.

"But I would make you wear plugs and spank you..." he tried convincing me.

"It's not only about sex." I informed and I could hear his sigh.

"I really want you asking me for permission to do things." He admitted.

"We'll talk about this at home." I told him and hung up not waiting for a reply.

Focusing on work was hard, especially with a box containing lingerie that was at least one size smaller than mine, but I did my best.

At the end of the work day I went home with the box and got home as fast as I could. I was greeted with the lights dimmed and Tony sitting on the couch with an amused look on his face "Don't complain." He said when I was about to take my breath to lecture him.

I glared at him and placed the box on the table before starring at him annoyed "Why?"

Tony clearly ignored my question as he got up and circled around me "What was your name during the play, Pep?" He murmured and stood in front of me.

I sighed "I'm not telling you." I muttered and looked down.

Tony smirked and watched my reaction carefully "Let's try the ones I'd use then." He teased "Pet? Brat? Toy?" He teased and chuckled as I blushed.

"Girl?" I heard him say and shivered.

"Girl, hmm? Cute, never thought of you vulnerable as one." He chuckled and kissed my lips quickly "I bet you're as flexible as a little one." He teased and I shut my eyes.

"Please stop." I murmured not liking how much he was getting to know.

"You forgot 'Master'" he pointed out amused.

I snorted "Please, Master." I mumbled and as soon as the words came out I looked up at him suddenly feeling a lot like a girl.
