Today is a quiet day at the office. I can follow my fantasy. I have a male and a female co-worker sitting with me in the same room. We don't have a problem with each other using our smartphones during work hours, so I can occasionally grab my phone and add to this fantasy. (I ended up adding to this text over the course of several days, I hope you like it.)

I was just alone for some time and took a few pictures of my cleavage when my male co-worker enters the room again. He checks out my chest, and I'm not surprised because he often does that whenever he thinks I don't perceive it. But I realize that this time also my blouse is still unbuttoned and suspiciously open. I try to button it up as unobtrusive as possible, but he turns his head to me and watches me for a few seconds before making a face and bluntly asking: "Do you sometimes take nudes at work?"
And because I'm intrigued about the idea of talking about sexual topics right in this moment, I say: "Yes." I leave my blouse a little open and I can see him getting as good a look as he can of my cleavage, and I realize that I want him to keep asking about it, just so that I can talk about lewd topics.

He says: "What made you start?" And that's the first time I thought about it in a long time. An old acquaintance of my mother asked me for lewd pictures of my tits a while back. That was when I finished my studies and started to work for my current company. When it's as quiet as today, I sometimes take nudes and sext him up.
I say: "A friend of my mom wanted to have some pictures at some point."
He says: "Oh, he wanted to fuck you? Maybe he still wants to fuck you…"
I say: "No, we just sext. I think his wife passed away some time ago, and he just wanted something lewd." And because the thought turns me on so much, I add: "But I'm sure he jerks his dick to my pictures and imagines fucking me."
And he says: "Oh, I'm sure he does."

I ask him: "What are you thinking about?", because I hope for some naughty revelations about my co-worker, and I'm not getting disappointed.
He says: "I'm frequently imagining fucking you, Vicky." When he says my name, I feel my clitoris twitching. And he continues: "I'd be very happy if you would send me all those naughty selfies of you as well. I would jerk my hard cock to your naked tits and imagine us fucking at the office." He checks out my chest very aggressively now.
I start being curious about how far he would go and I'm so very horny by now. I say: "Would you like to see my naked tits, instead of me sending you pictures? I could unbutton my blouse again." And I start to unbutton my blouse again, very slowly, examining every reaction that I get out of him.

He doesn't say anything, but his glance is fixated on my chest. I keep going, mainly because I want to keep going, and want to show him my naked chest. I open my blouse. I don't wear a push-up bra today. It is easy for me to pull my tits out of the soft cups and there they are, my naked tits out in the open, at the office, and it turns me on so much. He doesn't look away even once and I have his full attention. I say: "Check out my naked tits that you have been fantasizing about.". I hold them in my hands and slowly start to massage them. I say: "I want you to open your pants, show me your dick and how hard it got, and I want you to start jerking it for me!" He does as I say. I can feel myself getting wet.

For some time we're just watching each other. I start to massage my tits more firmly but also more slowly. Every once in a while he checks out my face expression, but when I massage squeeze my tits together, he can't look anywhere but my naked tits. His cock is already pretty hard. I like to see it that way and am already fantasizing about sucking on it. Subconsciously my hand wanders to my clitoris. When we both realize, his mouth opens a little like he's about to moan while jerking his hard cock in his hand and I say: "Oh, you like me going for my clitoris? I bet you'd like to see me fucking myself?" He moans. I say: "How about I start to massage my pussy while you let me suck on your hard cock a little bit?" As soon as I say ‘suck' he stands up and moves over to me, pressing his hard cock against my lips. I feel my nipples getting rock hard all of a sudden, that's how horny I am.

I'm thinking I can behave as slutty as I want at this point, and that my co-worker won't be surprised, seeing that he already had all these naughty fantasizes about us fucking at the office. I do enjoy licking on his dick so very much, it's bigger than I thought. He slips out of my mouth with a smack. I run my tongue over my lips, and while keeping eye contact, I say: "You have such a fat hard cock. I can't wait to feel you slide into me." As I run my tongue along his hard shaft right after I say that, I feel him cramp up and I slow down immediately as to not make him cum already, because I want to have as much as possible as long as possible of that big fat cock. I say: "Let me focus on my tits for a while, they start to feel so good." He grabs his dick and continues to jerk it right in front of me.

Our female co-worker returns and as she enters the room it takes me a few seconds to realize where I am and the fact that my tits are out and my work pants are pulled down as much as for me to easily be able to reach my clitoris. My male co-worker stops jerking his dick, but keeps holding it in his hand, I stop to massage my chest, and we both wait for her response to what's going on. To my surprise he starts to jerk his cock again after a few seconds, and I love it. I can feel my whole pussy twitch. I grab my tits again and continue massaging them, and as I do, I have to moan, because it feels so good. I look at her and ask: "Do you like what you see?" and she says: "What's going on?" I look at his dick that is sliding through his hand and say: "I made him rock hard and jerk his fat hard cock for me." He only moans so I guess his dick must be feeling very good. She leans over my desk and glances back and forth between his fat hard cock and my naked chest.

Now that I look at this big fat cock I realize how much I want to have it inside of me. I say: "Do you want to enter me with that big fat hard cock." He says: "Yes. Sit on your desk." As I get up and sit down on my desk our female co-worker opens her blouse and starts to massage her chest. I grab his cock and jerk it a little bit, just to get a feeling for how hard he is – he is fucking hard. I'm so fucking horny by now that I just get completely naked, and I don't fucking care if anyone else enters our room. I lean back on one of my elbows and lead him inside of me. He easily slides in since I'm so wet at this point. I pull my legs up. He grabs my upper thighs as he starts to move back and forth inside of me. As he fills me up completely I can't but imagine his big cock being back in my mouth again. I say: "When you need a break, I want to suck on your cock again and taste myself on your big hard cock." As I say this he thrusts his cock harder into me and I almost moan loudly.

I'm thinking this is not dirty enough and he tells our female co-worker: "Start to lick on Vicky's tits and suckle on her hard nipples as I fuck her." In order to tease him I ask him: "Am I being a good slut? Do you like us to fuck like this in the office?" He doesn't answer but starts to moan slightly and moves a little quicker inside me. I continue: "Do you want to fuck me again?" He gives a short grunt and then thrusts his big hard cock inside me as hard and fast as for my tits to start bouncing and rolling up and down my chest, hmmm, that's how much I need it. Our female co-worker stops to lick on my tits and her hand wanders over my belly and to my clitoris that she starts to massage very firmly. And now I have to stop because imagining getting filled up completely by a fat hard cock and someone massaging my clitoris at the same time is too much for me to handle right now.

(Would you like me to write down more of these fantasies? Or do you have a specific fantasy that you'd like me to write about? Given that it also turns me on...)
