"I think my little slave girl enjoyed that."

"Yes, Master. Thank you."

"Why did it turn you on so much?"

"I don't know," I replied. "The number of people watching, obviously. I suppose it's every exhibitionist's dream to have an audience ready and waiting. But it's more than that. It's the anonymity of it, as well, I think. Two hundred people, but I have no idea who they are: young, old; men, women; here in Britain or anywhere in the world; attractive, ugly. No idea, you just have no idea who they are. When I walk down the street tomorrow it might be them: the guy looking at me in the queue at Tesco's might have been watching me wank myself tonight. I'll never know.

"And what was really fun about that session was the extra cam. It was good to know you were still in charge, Master; to know that although I was performing for the audience, it was being done because you permitted it, and in a way which you were controlling. It meant I wasn't just a performing seal, performing for the group, responding to every instruction. I was being controlled by you, Master."

"Very good," my Master replied, smiling. "I knew you'd like it." He moved the second webcam back to his own PC and settled it into position so that it framed his head and shoulders. "So now to part two. Go and put on your silk nightie."

I was slightly taken aback, as I hadn't anticipated further developments so soon. Without demur, however, I went to the bedroom and pulled on my light, floaty nightie. When I returned my Master was chatting in the Freezone room and told me to do likewise. I fixed the camera on my face and launched into the barrage of comments which were immediately directed at me. The webcam emphasised my décolletage and, though I say it myself, I thought the tantalising glimpse of my breasts, small as they are, was rather attractive. Certainly the room seemed to think so.

"harriet show breasts"

"lower cam harriet001"

And so on. In the webcam picture on my screen, behind my right shoulder, my Master could be seen sitting at his own PC, observing the welter of chat directed at me. He was stripped to the waist and slouching comfortably in front of his screen, and as I watched I felt a surge of desire for him. As I was explaining to someone that I preferred my own fingers to a dildo, I saw him come behind me and felt his hands on my shoulders. I watched on the screen as they kneaded my skin, sliding down my neck to my chest and rubbing my breast bone. I smiled at his touch, tender and sensual, and delighted in the view it afforded on the webcam. He crossed his arms so that his left hand approached my right breast and his right hand my left breast; his fingers slid beneath the silk of my nightie and alighted on the swell of my breast, snaking towards my areolae; immediately my nipples began to harden, lengthening to their almost quarter of an inch size. My Master's fingers and thumbs rolled the nipples back and forward, squeezing them, drawing at once pain and pleasure from their sensitive flesh. The chatroom went crazy.

"harriet whose that behind you"

"do you know there's someone behind you"

"take dress off"

"let us see what hes doing"

"harriet show your breasts please"

"do you realise there's a guy behind you? lol"

It's a curious feature of chatrooms, which you may have noticed, that as soon as someone cracks a joke, half a dozen other guys immediately repeat the same joke in their own words. My Master slid my nightie over my shoulders, revealing the tops of my breasts. He held my nipples between forefingers and thumbs and stretched them forward, tugging at my breasts. On the screen they looked huge: hard and thick and ready to suck. My Master cupped my breasts and squeezed, pushing them upwards and outwards, kneading gently, displaying my nipples to great advantage. I felt his breath, warm and loving, on my shoulder, his mouth, so sweet, so hot, his tongue, tracking across my neck, and I felt like I was dancing with angels.

"Well, that's you turned on again," he whispered in my ear, grabbing hold of my hand. Pulling it behind me, he directed it towards his crotch, where I felt his own rising excitement.

"Mmm," I breathed. He returned to his own seat and I resumed my conversations with the room.

"harriet who was that"

"That was my Master," I replied.

"your master? woohoo. do you do what he tells you"

"Of course. Instantly. Without question."

This revelation swept through the room, as the guys instantly began to map their own fantasies onto my words. I guess it's probably most people's dream to have someone at their disposal, someone who will perform for them, who will serve and obey. Of course, as soon as the room realised I was submissive they tried to order me around. First, someone called jackal said "harriet, I command you to strip", and then everyone followed suit with their own variation on the theme.

"harriet take off clothes now. order"

"harriet001 I am a master. Show me ur breasts"

"im ordering you to strip now"

"Sorry guys, I only obey my Master."

My nightie was still pulled down over my left shoulder and I slipped my breast into view, stroking it as I chatted, feeling the tingle in my nipple as I squeezed and rolled it.

"harriet, huge nipples, lets see the rest"

"fantastic nipples harriet001"

They are, in truth, one of my best features, and I was as entranced by the sight of them on the cam as the rest of the room. My Master's impromptu attack on them had excited the room, and there were now 230 people in attendance. A record for us.

And then I saw it.

"Harriet001, your Master needs a blowjob."

And this time, I realised, the words were written by my Master. On the screen, I could see him smiling behind me, his hand rested on his crotch.

"Yes Master," I replied.
