I wake up to the shrill sound of the alarm. I am exhausted. I never thought I would say this. Sex has exhausted me. I look at the other side of the bed. I don't know why I was hoping he would be there sleeping. I sit up and stretch before getting up and going to the bathroom.

When I leave the room, I'm dressed and ready for a new day of work. There is no sign of Christian anywhere in the apartment. But there is breakfast ready and next to it, a sticky note. I take off the note while I read what it says:

I must say that last night exceeded my expectations. I never imagined that punishing someone would be so pleasant.

Christian.

Did he like punishing me?

I sit on the barstool as I slowly start eating breakfast. I close my eyes for a brief moment. I can't deny it. Last night had been, new, yes. Exciting, in extreme, of course. And deliciously torturous. I smile. I never thought I could enjoy sex the way I'm enjoying it with Christian.

My goodness!

Christian left with the pictures I took of him yesterday while training.

I finish my breakfast and look for my phone. As soon as I look at the screen I have a text message.

"I sent you the pictures in the mail, I hope they are useful"

I smile as I put my phone in my bag and walk to work.

I have a busy day today and I arrived earlier than usual. At 10:00 am I have the meeting with Men Fitness. I hope they like the proposal I have prepared for them.

I go into my office and turn on the computer. There I have an e-mail from Christian with the pictures I took of him yesterday. I download them and send them to print. And then I put them in a folder to show them to the magazine.

I have everything ready and it's still early. Elena hasn't arrived yet. I didn't see the car parked outside. So I go outside and rush over to the Starbucks for her morning coffee and another one for me. I still need to wake up.

When I'm back, I see the car parked in front of the office. Just looking at the car, my breathing speeds up. I almost stumble and fall throwing the two coffees, when I see the door open and Christian, elegantly dressed, gets out of the car.

He is wearing sunglasses as he turns the car around and opens the door at the other side. He holds out his hand to Elena, who gets out of the car with a smile as radiant as his. Christian smiles back at her as she holds on to his forearm to get out.

I freeze as I watch the scene. Neither of them sees me. Christian shuts the car door and she stares at him as she raises a hand to his cheek. He smiles even more as she strokes him tenderly.

What is happening here?

Elena leans over to him, stands on her toes as he approaches her face and kisses Christian goodbye on the cheek before entering the office.

I watch Christian, with an idiotic smile on his face, as he leans back to the car and watches her walk into the office. I frown. He told me he wasn't going to look at any more women. I resume my walk to the office. I try to ignore him at all costs, but as I approach the car, he stops looking at the office and notices my presence.

—Good morning Ana. —he greets me with a radiant smile.

The same smile he has given her.

I don't know why, after seeing the effusive exchange with Elena, I don't feel much like saying hello. I don't even know what that was all about. I know that he told me that he owed Elena a favor, so he's driving her around. But I never imagined that they would meet at that level of intimacy that they showed when he helped her out of the car. Or maybe it was my imagination.

—Good morning. —I tell him cordially as I pass him and walk towards the office without stopping.

—Are you all right? —he asks, making me stop immediately at the curb.

I turn to him.

—Perfectly.—I answer him as I resume my walk.

Suddenly I feel someone pulling my arm away from the road. He grabs my arm tightly as he pulls me to a place away from the sidewalk and office doors.

—You can't fool me, Ana. —he says, turning me over in his arms. —What happens?

—I never imagined you would have that level of intimacy with Elena. —I tell him by staring at him.

Christian frowned and looked at me very seriously.

—What do you mean?

—I'm not an idiot Christian, I saw you when you were helping her out of the car and the way you were both smiling at each other.

—Are you jealous? —he raises an eyebrow as I watch a crooked smile appear on his lips.

—No!— I yell at him in frustration.

—I told you that we know each other, nothing more. Between her and me there will never be anything.

But that doesn't make me feel any less possessive about him. How many friends like her will he have? How many will he give that smile that makes any woman melt on the floor?

—I like the dress you're wearing. —he says to me still smiling as he slides his eyes over my body.

—Thank you. I better get back to the office. —I tell him by stepping away from him.

—Wait a minute. —he says, coming back to my side.

I feel his breath in my ear.

—Get in the back of the car, take off your panties, and give them to me.

—What! —he can't be serious.

I can't walk around without my panties on at work. Especially when I have an important meeting at 10:00 am.

—Are you going to disobey me again? —he asked, raising an eyebrow.

Do I want to disobey him?

Well, it would be better than going around without panties all day. But I would also have to endure another of his tortures where he puts me at his mercy and leaves me sexually frustrated and on the verge of orgasm again and again.

I don't think I want to feel that way again. I look him straight in the eye and feel my belly twist with pleasure. He takes the two coffees out of my hands and nods towards the car.

—He's all yours.

I walk slowly to the car and get in the back and close the door. I take off my red lace underwear and place it on the steering wheel. I adjust my dress and get out of the car again. I walk towards him and take the coffees out of his hands.

—Thank you, I left a present for you in the car. —I tell him with a smile. —I hope you will return them to me before my 10:00 am meeting.

I don't know why I hope he will return them. I know he won't. I walk with a determined step to the office. As if I were not without panties.

—Good morning Ana. —Kate greets me as I pass her table.

I stop and examine her from top to bottom.

—How did you get home last night?

—I have no idea how I got to the apartment. —she answers while I laugh.

—Who sends you to drink so much. —I tell her with a smile as I resume my walk.

—But I'm clear about everything that happened, and you're not going to escape the interrogation regarding your roommate. —he says, pointing a finger at me.

I know what awaits me.

I knock on the door of Elena's office and she sends me in. She has a big smile on her face, which is unusual, by the way. I'm used to the serious and professional.

—Good morning Elena. —I tell her, leaving her coffee on the table.

—Good morning Ana. —she says, still with a big smile on her face.

—You are very happy this morning. —I make the observation in the hope that she will tell me why.

—Yes, I had a fantastic night. —she says to me very happily. —Everything ready for today's meeting?

—Yes.— I say with a smile. —Do you want to see everything before I introduce it to them?

—Of course I do. —she says, standing up.

And we head over to my office where I have all the stuff for the presentation. I show her everything. From the top candidates to the final candidate. Even the pictures I took of him yesterday in training.

—He's in good shape. —she says to me, admiring the photos.

I look at her sideways while she examines the photos carefully. She looks at them again and again as she slides her fingers through them.

—Do you mind if I keep this one? —she asks as she holds up a photo of Christian hitting the bag. —I want to show it to someone.

—Go ahead. —I tell her as she takes the picture.

—You've done a great job, Ana. I made a good decision to leave this project to you.

—Thank you.

—When you finish the meeting you can take the afternoon off. You deserve it.

—Thank you Elena. —I tell her with a smile as she leaves the office.

I have the problem of picking up my car solved. Now I only need the one for the doctor's office apointment. And she tells me she has an appointment at 2:00 pm. That's perfect.

After I hang up, I sit thoughtfully in my chair while scribbling with a pen on a piece of paper.

Who is Elena going to show the picture to? I imagine that she wants the photo for herself. And her comment that she had had a fantastic night, along with the memory of the scene I witnessed this morning, comes back to my mind. But is not welcome, because is torturing me. What if Christian lied to me? What if the fantastic night was with him?

I don't doubt it, I know what Christian is capable of doing in bed and out of it.

But why would he lie to me about it?

Why wouldn't he tell me that he had given in to her wishes? Why wouldn't he tell me the truth? Why wouldn't he tell me what role Elena plays in his life?

I know that deep down it is my fault. If I had accepted a relationship with him, a normal relationship as he had asked me to, he might not have had the need to go after another one. I have to stop thinking about it so much. Maybe it's all just machinations of my mind. Maybe everything he told me is true and she is just a friend.

The meeting is half an hour away. I have everything ready and I'm about to go to the meeting room and leave everything in order, when someone knocks on the door.

—Go ahead. —I say to whoever is on the other side.

And I sit back in the chair as soon as I see who's coming into the office.

—What are you doing here? —I ask, frowning.

The last thing I expected was for him to come to my office at this hour. He doesn't answer me. He walks with a steady pace and sits in the chair in front of my desk while tilting his head sideways.

—Do you want something? —I ask, trying to make my voice sound firm. But I know I can't. He has a power over my body that I don't know about.

—Of course, I wouldn't be here without a reason. -he says in his characteristic voice.

—You will say.

—Open your legs. —he says to me in a sensual tone.

—You are crazy! I'm in my office, anyone can come in.

—I closed the door as soon as I came in. —I didn't notice that.

—I have to get ready for the meeting, Christian. I don't have time for this. —I say standing up.

I don't realize that he stands up quickly and corners me against my desk.

—Would you rather I took you on the table and made you scream with pleasure? —he whispers to my lips.

—Why are you doing this to me?

—You agreed, remember. Where, how and when I want.

—But not in my office. —I say to him in a whisper, losing what little sanity I have left.

His smell is beginning to cloud my senses and he hasn't touched me yet. If he puts a finger on me, I know I will let him do with me what he wants.

—Then what will it be. —he says, sliding a finger from my shoulder all the way down my arm. His gentle caress makes me shudder completely. If I were to wear panties right now, they'd be wet for sure. So I squeeze my thighs. —You do what I ask or I take you wildly so that the whole office listens. — he says as he gives me a light kiss on the neck.

I hold on to his arm because my legs have started to fail me. My body is reacting to his touch and presence. And I'd better answer him something coherent before my brain decides to shut down and let my body act on its own.

—I think I'd better sit down again.— I answer as I separate from his body and return to my chair.

—Wise decision.

It will be best. Christian sits down again in front of me. He stares at me one more time.

—What do you want, Christian? —I ask him in a tired tone once more.

—I was so absorbed last night, that I forgot to mention that we had started with another lesson.

—Another lesson? —If it's driving me crazy with pleasure, he's getting it without any effort.

—Submit yourself to someone's will, without prejudice and without protest. —he says to me without taking his eyes off mine. —Now, open your legs. —he says to me, leaning back in the chair, raising his legs on my desk and lowering his gaze.

I stare at him as I slowly open my legs and he slides his thumb down his lower lip, pensive.

—Touch yourself. —he says to me without looking away from between my legs.

I think about it for a brief moment. He has already warned me that he will take me here and make me scream if I do not obey him. And I have no doubt that he will be able to do so. So, I slowly pull my dress up to my waist and under one of my hands towards my sex.

—Slowly caress yourself. —he says to me as I slide two fingers across my sex. —Don't put them in. —he warns me with a firm voice.

The tone in which he speaks to me makes me even more excited. I slide my fingers slowly over my wet sex and hold back a moan as I bite my lower lip.

I have never masturbated in front of anyone in my life. The other day at the club, I had only stroked myself because he had asked me to. Like now. But I hadn't gotten much further. But this is totally different. Not only because I know what he wants in the end, but because I'm in my office, without panties and about to masturbate for the first time in front of a man.

I slide my fingers slowly up and down, making the moisture between my legs increase even more. I control the involuntary impulse of my legs to want to close so that he doesn't see. I throw my head back while closing my eyes to the increased pleasure.

—Look at me. —he asks me authoritatively.

I open my eyes and straighten my head. He is looking at me with desire. I can see his normally blue eyes, darkened with pleasure.

—Only one. —he asks me in a hoarse voice.

And I obey. I insert a finger inside me as I moan and close my eyes briefly.

—Move it in a circle. —he asks me again as I fix my gaze on his.

I obey him. But this is something I know how to do. I know how to achieve an orgasm this way. It's not something he has to teach me.

—Introduces another one. —I moan again. —With the other hand, touch your clitoris.

I look at him with one eyebrow, but under my other hand and as I open my folds with two fingers, I begin to caress that sensitive part of me. The pleasure is increasing and I cannot keep my eyes open, nor can I contain my moaning. I bite my lower lip. Someone is going to hear me from one moment to the next if I don't.

—Open your eyes, Ana. Touch the front wall.

—Mmm. —this is too much.

I am no longer aware of what I am doing. I am ecstatic. And I quickly feel my walls tighten around my fingers. I close my eyes again and pant with pleasure, I am on the verge of an orgasm.

—Do you like what I do to you? —I feel his hoarse voice in my ear and I force my eyes open. —Don't stop. —he asks me as he pulls my chair back.

I feel the heat of his breath on my neck, but he doesn't touch me.

I don't stop. I continue until I can't take it anymore and as I bite my lower lip I let go with a deafening groan.
