I'm not proud of doing it. But on the other hand I am. Christ, I don't know, I can't begin to analyse what I'm doing in all of this. Anyway, I did it. My hands were trembling as I sat on the toilet seat and peeled off my panties and slid them into my bag. I smoothed down my skirt and sashayed back to my desk as proudly as I could, observing everyone as I passed, seeing if I could tell who had that extra leer on his face. I felt naked, exposed.

I settled into my chair and switched the cam on. After verifying and logging in, the picture flashed up on my screen. It was too dark, nothing to be seen except a swishing presence which could have been a fish in a tank or a ghost swooning in the moonlight.

[str8guy] Switch on the torch

[medusa] cant

[str8guy] Molly, sweet, just do it, there's a girl.

[medusa] dont fucking patronise me

But I did it. Hoisting up my skirt, I scrabbled on the floor and reached out to switch the torch on. Tess looked at me incredulously as I re-emerged from the bowels of my desk.

"What the hell are you doing?"

"Lost my pen."

"Again? You ought to get a bloody lead for that thing. It's got a mind of its own."

I looked nervously at the footwell. The rear was bathed in soft light from the torch, but it diffused as it neared the front and mingled with the lights in the office. From behind me, it wasn't at all evident that there was a torch shining down there. With some relief, I turned to the screen.

And saw my legs in bright detail. Very bright detail. Quite shocking, in fact.

[str8guy] Isn't that lovely?

[str8guy] What a pretty view, isn't it Molly?

[str8guy] Just think, everyone imagines you're sitting there, all demurely, doing your work like a conscientious employee.

[str8guy] And all the time, here you are...

[medusa] uh huh

[str8guy] Showing yourself off to an under-desk camera.

[str8guy] Molly the little upskirt girl.

[str8guy] With a camera under her desk, showing me a picture of her legs, her lovely legs. It's very naughty, isn't it?

[str8guy] Very naughty.

[str8guy] Isn't it exciting, Molly?

[str8guy] Just a bit?

[str8guy] Knowing that you're showing yourself to an under-desk camera while everyone around you is working normally.

[str8guy] Tell me that isn't exciting?

[str8guy] Tell me Molly. Try and deny you're excited.

[medusa] okay i am, a bit

[str8guy] Just so. I knew you would be. I knew you'd like this Molly. I can tell. I'm getting to know you so well now, aren't I?

[str8guy] Could you sit further forward Molly. Rest your arms on the desk.

[str8guy] Oh yes, that's it. Much better detail

[str8guy] Molly, spread your legs for me

[str8guy] Please spread your legs

[str8guy] Show me your pussy

[str8guy] Oh there it is. Beautiful bald plaything

[str8guy] I'm falling in love with your pussy, Molly

[str8guy] Molly's pussy. Molly's polly.

[str8guy] That's what I'm going to call it from now on.

[str8guy] Do you like that name? Molly's polly?

[str8guy] It's so bright and beautiful. Perfectly in focus, too. Part your legs further

[medusa] cant. my skirt's in the way

[str8guy] slide it up then. Pull it up over your bottom Molly

[str8guy] Yes, yes

[str8guy] And further

[str8guy] and furthre

[medusa] cant. i'll be seen

[str8guy] Don't be silly Molly. Who can see behind your desk?

[medusa] if someone comes

[str8guy] Well just watch out. If someone approaches you'll have time to pull it down, won't you

[str8guy] Now pull it up

[str8guy] completely over your bottom

[str8guy] Put your naked bottom directly on the seat

[str8guy] Oh god yes molly, that's it. You're doing it.

[str8guy] and spread

[str8guy] Spread your legs

[str8guy] Wider

[medusa] thats as wide as it goes m8. desk is in the way now

[str8guy] beautiful

[str8guy] Molly...

[medusa] ?

[str8guy] Touch yourself

[str8guy] Feel your polly

[str8guy] Oh god yes. That's it

[str8guy] Isn't that beautiful Molly? Isn't this the sexiest thing you've ever done? Fingering your polly for me?

[medusa] its kinky thats for sure

[str8guy] No, keep playing with yourself Molly. Type one handed if you need to.

[str8guy] Keep stroking yourself

[str8guy] There you are, in the middle of your office. Tess beside you. Others close by. None of them knowing what you're doing

[str8guy] All of them working like the little saddoes they are. Just think if they could see what you're doing.

[str8guy] if they could see your polly. Your hand on your polly, fucking yourself, Molly

[str8guy] oh stroke it, stroke it

[str8guy] I can see it gleaming. I can see your juice molly

[str8guy] show me your clitoris

[str8guy] Who'd have dreamed you would be doing this Molly?

[str8guy] Two weeks ago, if someone had said you would wank yourself in the middle of the office, what would you have said?

[medusa] :-(

[str8guy] Oh not a sad face, Molly! No, no. I think you're njoying this, aren't you?

[str8guy] Stroke, Molly. Keep stroking. Keep stroking.

[str8guy] And roll your fingers around your clit

[str8guy] Are you looking out, making sure no-one is coming?

[str8guy] You don't want to get caught do you?

[str8guy] That would be terrible.

[str8guy] How embarrassing. Caught with your skirt up, knickers off, playing with yourself on camera.

[str8guy] Part your lips wider. Let me see

[str8guy] Now move your fingers away

[str8guy] Oh yes, what a view. Perfection Molly

[str8guy] my beautiful cunt. my beautiful cunt, Molly's polly, my beautiful cunt.

[str8guy] Thank you for giving it to me Molly

[str8guy] Thank you so much

[str8guy] make yourself cum, Molly

[str8guy] I want you to come.

[str8guy] But do it quietly. Don't want anyone to hear, do we?

[str8guy] Please Molly, come for me

We were interrupted at that point. Tess began talking to me, and I was in a dream, watching my soaking pussy in close-up on my screen. I was getting pretty damned close to coming, I have to say. str8guy's continual commentary was leaving me completely turned-on and my fingers were applying some serious attention to my clitoris and lips.

I realised almost too late that Tess had got up to approach my desk. In a panic I tried to slither my skirt around myself again, heaving it over my hips and sliding it down my thighs. I blushed redder than a baboon's arse and flicked my screen on to a pre-prepared spreadsheet with the costings of my latest bid application.

My heart was hammering, louder and more violently than anything I've ever known. This was genuine terror, more severe than anything I've encountered in my entire life. Even worse than the time I was faced by two lorries careering towards me and I had to throw my Fiat Uno up onto the grass verge to avoid them.

That would have only been a car crash. This would have been a life crash.

"Where we going on Friday?" I asked, trying to say something - anything - to make myself appear normal.

Tess stared at me incredulously. "You know perfectly well where we're going. We talked about it yesterday. Walkabout."

"Oh yeah, of course."

"Hmm, I'm beginning to wonder about you, Molly. Your brain seems to be turning to mush. Can't keep your pen under your grip. Forgetting conversations from only the day before. Premature Alzheimer's, that's what I think."

"Hmm, yeah you could be right. Who are you, again? Where am I?"

So that was all earlier, and cut and pasted into my diary. It's eleven-thirty pm now, and I'm going to bed. What a day! I think I got away with it.

That was too close though. No more, no more str8guy. You're not going to do this to me any more.

Silver, here boy...
