As I watch him disappear, my brain is thinking at full speed. I don't want him to leave. I need him. I need his gaze on mine, I need the touch of his fingers on my skin. I need to feel that connection that I have never felt with anyone before.

—I don't want to see you having sex with another person, Ana...

His words come back to my mind again and again.

—If you were mine, I wouldn't share you with anyone...

Christian has feelings for me. Feelings much deeper than he has confessed to me. Only a person who has given his heart, without the other person knowing it of course, can speak that way. As if it hurts him to see me with someone else.

I put my thoughts aside, I'm thinking nonsense. I take a towel and dry myself quickly while I put on my dress and follow him out. By the time I reach the hall, he is gone.

Shit!

I take the heels in my hand and go outside. There's no sign of Christian anywhere. Maybe he's in the office. I walk over there while people are looking at me funny, like I'm crazy.

Of course I just got out of a shower and I'm still completely wet, in every sense of the word, while I'm holding the heels in my hands. I arrive at the office and open up without touching. There he is sitting on the black leather chair with his head in his hands.

—I said not to bother me. —he says in a defeated voice without looking up.

I gently close the door and lie down. I watch him from there. He has not yet noticed my presence. So I take the opportunity to look at him and think about everything that has happened in the last 72 hours.

Christian has impressed and stupefied me, on more than one occasion. And I know that his words are sincere when he says that he couldn't see me with another person. As I watch him, I feel a strange sensation. As if I really belong to him. And the need to feel him inside me, grows every second I look at him. And then I smile to myself. There is no one way to know myself, there is another variable that has not occurred to him, and it has just come to my mind. But first, I need to fix things.

—I'm sorry.

Christian raises his head and looks at me not believing that I'm standing here.

—Please leave, I want to be alone. —he says to me as he looks away from me.

—Christian, forgive me for hurting your feelings.— I say as I walk in his direction. —I think I drank too much tonight, and I did something stupid. —I end up stopping in front of him.

—What was the stupid thing you did, Ana?

—There were several, mainly what I told you. —I pause. — I know I'm not one to criticize what you do with your private life.

—Then why did you do it?

—Because, even though I told you I don't want a relationship, I can't stop thinking about you. —I I tell him as his eyes open with surprise.

—What do you want from me?

—You told me that the only way to know myself is through BDSM.

—Yes.

—And you also told me that you used to practice it, that you were a master.

—Where are you going with this?

God! I don't even know how to do this. But since what I know of this world is from the novels I've read, well, I have no choice. I let go of my shoes and kneel in front of him, placing my hands on my legs and bending my head.

—I want you to take me as your submissive and teach me to know myself. —I say to him as I feel him let out an exhalation.

—I'm sorry Ana, but that can't be, get up.

—Why not? — I ask him and look up even from the floor.

—Because I've already left that world behind, and I don't take any submissive.

—Why not? I thought that...

—I don't want to talk about it.

—I will not get up until you agree to be my master.

—You don't know what you're saying, Ana.

—Explain it to me then.

—You don't know what it's like to be given orders all day long, orders you have to follow or there will be consequences.

—So far I have been very good at following your orders.

He stares at me. I think he is hesitating to accept or not.

—If we do this, and it does not mean that I have accepted, I have my conditions.

—Of course. —I tell him with a smile.

—It will only be for a week, I don't think I can do it any longer than that, and you won't be able to fuck anyone else but me during that time. —he says to me in an authoritative way.

—Okay.

If I have him, I don't think I want to think about anyone else.

—We'll fuck, wherever I want, however I want, whenever I want. —just hearing him talk is turning me on.

—Mmm hum. —I say to him as I feel my belly muscles tighten.

—You will not be my submissive.

—Aha. Something else?

—Yes. One last thing.

—You will say.

—The moment you feel you can't continue this deal, you must tell me, Ana.

—I don't understand you.

—I know that I have given you orders, but that doesn't compare to what I can become in master mode. I am going to be demanding to the point of almost painful extremes.

—Will we need a safe word?

—No. Just tell me it's enough. That you don't want more, and I'll stop, we'll finish our agreement and I'll leave.

—You leave?

—Yes. There's not much point in continuing to live together.

I don't understand. But in the same way, decided to accept. I'd rather have him by my side for a week than no time at all. A week of sex with Christian. That sounds like a fantasy to me.

—It sounds good to me. —I tell him I accept his conditions.

—Good. We have 1 hour and 10 minutes left to officially start being your master. What do you want to do during that time?

—Mmmm. I can think of several things. —I tell him with a seductive smile.

—Me too. But first we need some things. —he says as he takes me by the hands and stands me up. —Put on your shoes. —he says as I quickly obey.

—Where are we going? —I ask him as he leads me out of the office.

—To go shopping.

He's not kidding. We leave the club and go shopping. But not just any kind of shopping. Christian takes me shopping at a sex shop. And while Christian goes deep into the store, I stand in the entrance where the sexy lingerie is. I look at the hangers that call to me. I approach them and slide my hands over the clothes. I take one of the hangers and take a good look at the garment. It is pure lace and tiny. I touch it carefully because I feel that it could break at any moment because of how delicate it looks. I don't have this kind of lingerie. I look at the hangers. There are all kinds of colors that exist and will be used. And then I think of something. I approach the counter with one in my hand.

—In this size, do you sell it in packages? —I ask her while the woman looks at me raising an eyebrow.

—We only have blue, red and black available in packs of 10.

—Give me one of each.—I say with a smile. —You can put it in a dark bag, I don't want him to see it, it's a surprise.—I tell her while she smiles at me.

I look to the back of the store, Christian is still looking for things. I hope it takes long enough for my shopping to be ready before she return. I don't want him to find out what I just did. The woman returns with the three packages of lace thongs wrapped. They don't take up much space.

I pay her and take the bag in my hand just as Christian returns. I walk away from him and spend some time looking at some things while he pays for all his things and we leave the store.

—Did you find something you like? —he asks me as he looks at my hands where I'm holding the bag.

And I just shrug my shoulders.

—There was something I liked. —I tell him with a smile as we get to the car.

Christian carries two bags, quite large in his hands that I don't dare look at. I open the door of the apartment and go to my room.

—Ana. —he calls to me with that seductive voice that makes my whole body react and my legs shake.

Yes. —I answer him as I turn around and see him looking at his watch.

—For this to work you must answer with total honesty, understand?

—Yes.

—It is essential for you to know yourself.

I am anxious and excited. So much so, that I have lost the ability to speak and can only think of monosyllables.

—In five minutes... —he says to me as he puts the bags down and begins to unbutton his shirt. —I want you here in the middle of the room...—he takes his shirt off and drops it on the floor.

I know he said something else, but I stopped listening to him when he took his shirt off. And I stare at his body. I can't get enough of this. All I can think about is sliding my tongue all over his naked torso and beyond. I bite my lower lip as I imagine his por limb in my mouth.

I groan as I slide my tongue across my lips. I don't think I've ever wanted a man as much as I want him.

—Are you listening? —his question takes me out of my reverie.

—Yes, in five minutes here. —I tell him as I walk quickly to my room.

I throw the bag on the bed and look for one of the thongs I just bought. I take a blue one and put the rest away. I take off my dress and put it on. The fabric slides smoothly down my legs. It's as if I have nothing on. What should I wear? I ask myself as I look into the closet and then look at myself.

He didn't say anything about what I should wear, so I smile for myself as I go to the bathroom and put on some makeup. I am ready. I take a deep breath before heading out into the living room in a blue lace thong and heels, nothing else. I peek out the door of my room. Christian has his back to me while holding something in his hand that I can't identify.

And I start walking in his direction. He turns to me when he feels my footsteps. But I don't stop, I continue walking until I stop in front of him. And I can see the surprise in his eyes when I stop. His eyes slide all over my body, he stops more than he should in the thong, and he looks up again. When he returns to rest his eyes on mine they are no longer blue, they are black.

—Didn't you hear what I said, right? —he says as he drops what he has in his hand on the sofa.

I remember his words from before, "for this to work you must answer with complete honesty...it is essential for you to know yourself"... And that's exactly what I'm going to do. I would never think of telling a man what I think. But if it's to achieve my goal of knowing myself, then I don't think I have much choice.

—I stopped when you took off your shirt. —I answer him honestly. Just like he asked me to do.

—That means that it affects you to see me without a shirt.

—You have no idea. —I tell him as I slide my eyes over his whole body.

—Illuminate me. —I return my gaze to his eyes.

—All I can think about is sliding my tongue across your naked torso...and down.

—Do you want to know yourself or me? —he asks, raising a eyebrow.

—Me, but I wouldn't mind getting to know your body in the process. —I tell him with a smile.

—Since you didn't listen to what I said, at least part of it, I'll remind you. —he says as he places his hands on my waist.

He has both thumbs in the center of my belly and draws circles with them as he bends down in front of me. His hands never move from my waist. My breathing quickens, even more, as I look down at him.

—The last thing I said to you was to come naked. —he says in a whisper as he lowers his hands to the edge of the thong. —And you have disobeyed me, doubly so. —he says as he looks down at my heels.

—What are you going to do about it? —I ask him, making him look up from my heels.

He gives me a wicked smile. I know he's planning something, but I have no idea what it is. He brings his nose up to the thong.

—Did you just put it on? —he asks as he moves his head sideways, sliding his nose across my belly.

—Yes.— I answer in a gasp as I close my eyes.

—Is it new?

—Yes.— I think the monosyllables are back.

I do not understand this inability to speak when he looks at me, or touches me.

—Did you buy it for me?

—Yes.— I tell him without being aware of what I just said.

Christian stops the movement of his head. I feel him press his thumbs on my belly and let go of my waist. I open my eyes just as he grabs the thong with both hands and unravels it into two pieces of cloth that he drops to the floor.

My breathing has accelerated. It's the first time someone done this to me. I never imagined it would be like this, so sensual, so erotic. I think I was right to buy so many, because I just discovered something about myself that I didn't know.

I like to have my panties torn off.

He looks up and stares at mine. He stares at me from below. I am totally turned on and can only think of one thing while he continues to crouch in front of me. To feel his mouth on my sex again. But as if he knows what's going on in my perverted mind, he gets up off the floor, ignoring it.

—It is too early for this, you must first learn to control your most primitive urges and desires. —he says as he turns away from me.

—I want your mouth on my sex. —I beg him.

He smiles at me, with that mischievous bad-boy smile.

—Have you always been this daring? —he asks as he turns to the couch.

—No. But seeing you half-naked is starting to affect my senses. —that and the alcohol I consumed today.

—Not today. First you have to learn the basic rules of a relationship like the one we're going to have. —he says, still with his back to me.

—And are we going to discuss them while I'm naked?

—Of course. —he says as he grabs something from the couch and turns to me.

Christian holds a small box in his hands. It is black. As I look at it, I don't know why, a chill runs through my body. Do I want to know what's inside? Of course I do. But I'm also afraid to find out what it is.

—What's inside? —I ask curiously as I look away from the box and stare into its eyes.

—Open it. —he says to me in the same sensual tone he used in the club.

I take a step closer to him and raise my trembling hands to the box. I don't know why I'm shaking. Perhaps the excitement of discovering something new inside, something unknown to me. Unknown and exciting I imagine. My fingers brush the soft black velvet of the box. I look into its eyes again. I still have my doubts.

—It will help you to know yourself. — he says to me with a smile.

I look at the box again. I take a deep breath and open it.
