I stand there and stare for a moment at the small object inside.

—It's a vibrator. —I say in a whisper.

I know what it is, I've seen it. But never in my most perverted fantasy has it occurred to me to buy one. I am not one of those women who has a dildo stored in the drawer next to her bed to give herself pleasure when she is in need. I dry swallow and look away when I understand why he is showing me.

—Do you expect me to use it? —I am curious.

But he keeps staring at my face and analyzing my facial expressions. He brings one hand closer and slides it across my cheek, almost as if it were not touching my skin. His caress feels as soft as the velvet of the box I just opened.

—Have you never used one? —his question brings me back to reality.

—No.—I answer quickly.

—Have you ever used any other sex toys? —he asks me as I feel my cheeks burning even more.

—No.—I tell him without taking my eyes off of his.

I can see the surprise reflected on his face at the answer I am giving him.

—Do you know what bondage is?

—Yes.—I say with a smile.

—Have you done any bondage?

—No. Just because I know the meaning doesn't mean I've practiced it.

—Have you ever done any BDSM? —he asks me now in astonishment.

—No.

I've never practiced that kind of sex. Of the pervert. But I have fantasized about it. More recently when I wanted him to tie me up with the wraps he was putting on his hands. I don't know what I would feel, I don't even know if I would dare to do any of that. But it must be exciting to see you tied up and subjected to someone's will while being savagely possessed.

—Have you ever fantasized about any of that?

—Yes.

—Tell me one of those fantasies. —he says as he pulls the vibrator out of the box.

—I fantasized about you tying me to the bed with your kick boxing wraps.

—Really?

—Yes.

—What a coincidence. —he says as he gives me a smile and walks to his room.

He comes back a minute later with a black T-shirt on and one of the wraps in his hands.

—I have a fantasy too, Ana. —he says to me as he twists the fabric in his hands.

While he does that, I remember scenes from novels I have read, from movies I have seen, where they tie someone to the bed. And I quickly feel the moisture between my legs.

—Are you going to tell me about it? —I ask without taking my eyes off his hands.

—Maybe someday, I don't think you're ready to deal with that.

—That means that you haven't accomplished it yet.

—No, and enough talk, come on. —he says as he takes my hand and leads me over to the couch. —The basic rule of such a relationship is obedience. Lie down. —he says as I do what he asks.

—Should I obey you in everything?

—Do you trust me Ana?

—Yes.—I answer without even thinking.

I know I can trust him. That if necessary I can trust him with my life, that he will take care of me, protect me.

—That is basically obedience. Giving up control to the other person knowing that he won't do anything to hurt you. —he says to me, staring at me. —Now open your legs.

I don't even hesitate to do what he asks. I want to know what he's going to do with me.

—Are you wet? —he asks, raising an eyebrow.

—Yes.— I say in a whisper.

I'm not used to talking so openly about my states of sexual excitement.

—If so, we won't need to wet this. —says to me as he brings the vibrator to my sex and puts it inside. —Done. —he says, reaching out to lift me up.

I stare at him. I don't understand anything he's doing with me.

—What are you supposed to put this on me for? —I ask him as he sits next to me on the couch.

Christian turns on the TV, sets a code, and then a specific channel. And then my eyes open wide to see what he just put on.

—You're not serious?

—Here begins your next lesson. —he says to me as he holds a small remote control in his hand, which I imagine belongs to the vibrator inside me.

—I thought we were going to discuss the rules of our relationship?

—There is only one rule. Obedience. Now, you are going to learn how to contain an orgasm. —and press the button.

The vibrator starts buzzing inside me with a gentle rhythm. And the vibration is joined by the moaning of the movie he just played. How am I supposed to hold an orgasm when the muscles inside me are twisting deliciously? I've never been in a situation like this before. I've always had to work hard to achieve it, but never to hold it in. A groan escapes me.

—Don't concentrate too hard, Ana.

—And how do I do that? —I tell himo as I bite my lower lip and I'm moving uncomfortably on the couch.

—Don't think about the vibrator, or the movie.

—It's very difficult not to do that. —he laughs.

—Do you want to feel me inside today?

—Yes. —I almost scream in a whimper.

—Well, don't come, If you do, that's the orgasm you'll achieve today. —he says as he looks away from me.

But it will be a son of a bitch. I watch him concentrate on the movie, or so it seems to me. I try to forget the vibrator inside me, but it's very difficult when the heat starts to build up intensely between my legs. I try not to concentrate on what it does to me or on the moaning that is heard throughout the room. What can I think of that will make me forget the impending orgasm that is growing more and more in the lower part of my body?

Something unpleasant.

I need to think of something disgusting that will make me completely forget what I'm feeling. Suddenly I find myself remembering the vomiting from the last drunk I had. That was pretty disgusting. The very smell of whiskey makes my stomach turn. As I remember that, I forget everything around me, I almost forget the vibrator. Almost. I remember it again when the intensity of the vibration increases. I must think of something else. Then images from the last documentary I saw come to my mind. A documentary about disgusting foods. Then I switch to the food that I hate and makes me want to vomit. I continue to think about unpleasant things until Christian interrupts my thoughts.

—You haven't come. —he says taking me out of my thoughts.

Only now am I aware that the TV has turned off and the vibrator has stopped. And that I have complied with his order. I have not come.

—Ah, yes. —I say to him in amazement. —How much did I endure?

—A little over an hour. —he says with a smile. —How do you feel?

—Honestly, about to explode. —I tell him as he smiles.

—It must have been hard for you to hold back for so long.

It has been difficult. But I guess that's not why he's asking.

—Why do you say that?

—Because I have seen you reach orgasm without me touching you. —he says with a smile.

—I usually have a hard time reaching it, but with you that's changed. —I confess to him.

—Hold on a little longer. —he says to me as he picks up the bandage from the sofa. —Hands in front.

Without thinking, I put my hands in front of him. He arranges them for me as he passes the wrap through my hands and ties them together. He stands up and pulls me to my room. I follow him without protest as he leads me to the shower. He stops underneath it, passes the wrap over the pipe and pulls it up, making my hands rise but not stay stretched. Then he ties the wrap back on my hands. Only when he has me tied up does it separate from me. He looks at me from top to bottom and smiles satisfied with his work as he passes his knuckles over his lips.

I am in heels, excited and tied up in my shower with one of his wraps.

—How do you feel? —he asks as I watch him undo his jeans.

—Excited. —I tell him without believing it yet.

—For seeing me or for finding you tied up and at my mercy? —he asks as he takes off his shirt.

—For being tied up and at your mercy. —I tell him as I watch him pull down his jeans and boxers.

The excitement I felt when I saw him was overshadowed by the moment he tied my hands.

—Opens your legs. —he says as he pulls his clothes aside and approaches me.

He doesn't touch me, but he directs his hand towards my sex by quickly pulling the vibrator out of me.

I almost convulse.

He puts the vibrator aside and looks for a condom in his jeans. I can't take my eyes off him anymore and everything starts to go in slow motion, his hands sliding all over his member while he puts on the condom. The craving grows inside me.

He approaches me, takes one of my legs and lifts it up to his waist. He sticks his forehead to mine and his lips brush against mine.

—I need you desperately. —he says to me as I feel the tip of his limb brushing against my entrance, tempting me.

—So take me. —I pant against his lips. —I can no longer bear this torture.

Christian joins his lips to mine. And as he kisses me slowly and delightfully he begins to enter me, tearing away a groan of pleasure. When he enters completely, he remains very still inside me.

—Did you imagine that I possessed you like this? —he asks against my lips as he begins to move slowly. —Or do you want to see the wild animal inside me? —he says, stopping his movements.

I can't talk, not when he has me on the verge of orgasm with one movement. I feel my walls clinging to his limb without wanting to let it go. He comes out once more and comes back in me just as slowly as he moans against my lips.

Then it quickly comes out of me and spins me around making me face the wall.

—I know what you want Ana. —he whispers in my ear as he pulls my hair aside.

My whole body shudders with his breath. He places one hand on my back and slowly reaches inside me once more, and stands still inside me.

—You want me to fuck you as I fucked her, with the same intensity as I hit the bah. —he says to me as his hands go down my body and squeeze my buttocks. —Don't move a single muscle. —he says as I feel his breath on my neck.

His lips settle there, delicately. He deposits a kiss and moves from my neck.

I try to move against his body, but the strong grip on my waist prevents me from doing so. I need him to move, but he is not in a hurry. I know a trick to tempt him, although I'm not sure if it works or not. I've tried it with the last few jerks and when I asked them if they felt it, they said they didn't feel anything. It doesn't hurt to try. I contract the muscles in my vagina around their member and then relax them. I wait a moment and do the same thing again. One last time, if he don't react, it doesn't work. I repeat the same thing one more time. I feel it moaning behind me.

—What are you doing? —he says in a hoarse voice.

—Nothing. —I answer innocently as I repeat it again. —You told me not to move, and I didn't move.

—I was referring to no muscle in your body, Ana. That "nothing" is distracting me from what I am trying to do.

I don't know what he' s trying to do, but my patience is running out.

—What are you trying to do? —I ask him as I turn my head over my shoulder.

And I find his lips close to mine. They are tempting me as I stare at them. His eyes are closed. I don't know what's going on in his head, but right now I wish I could be able to tell what he's thinking.

—Christian!

—I just want to memorize every moment. —he says in a whisper before opening his eyes.

And then he joins his lips to mine. It's not a slow kiss. It is a devastating kiss. A passionate kiss, like the one he has never given me before. The kiss is almost violent and I understand why, when he separates his lips from mine. Put a hand on my shoulder, firmly. And then it starts to move inside me.

I remember his words. He told me that the first time he was going to take it easy, because I had not had sex for a long time. But he changed his mind. His movements are not calculated, nor slow, nor sensual. They are accurate, hard, possessive. Christian makes his possession of me clear at every onslaught. I hold on tightly with my hands to the wrap as I groan audibly. The orgasm sweeps away all my senses. My eyesight blurs as I try to stand. But it doesn't stop. He moves his hands towards my breasts. And as he holds me, he presses and pulls on my nipples.

I don't know how he does it, how he demands from my body what I think I am unable to give him. But I feel the muscles under my belly begin to tighten once again.

I don't know if it's another orgasm, or if it's the same one that hasn't ended yet. It is impossible to separate the intense sensations I am feeling. I only know that I hear it moaning behind me, I feel it hardening even more inside me. I move against his body receiving his stabs. He groans audibly and I groan anyway.

—Ana! —he shouts my name when with a few more movements we both reach orgasm together.

The only thing that keeps me standing is his hands holding my body by my breasts and the wrap tied to my hands. This has been too much for me. Too much for one day. I know that tomorrow I will not be able to walk. And I also know that I will look like a zombie for not having slept enough hours.

When his breathing slows down, he comes out of me and unties my hands. He rubs them, bends down in front of me and takes off my heels. I no longer remembered that I was in heels. He pulls them aside and opens the shower as he holds me in his arms.

—We're going to take a shower, we need to sleep before we go to work tomorrow.

He separates from me while giving me a smile. I don't think I have the strength to stand up. By the time I finish bathing, my eyes almost close. A yawn escapes my lips as I put on my sleeping clothes under his watchful eye.

—Let me take you to bed. —he says as he quickly carries me in his arms.

I laugh out loud as I let myself be carried to my bed. He lays me down, covers me with the quilt and smiles at me. I don't remember anything else. As soon as I curl up under the comforter I fall into a deep sleep from which I know I won't wake up until the next morning.
