I read an article the other day that said that the average woman has 10 sexual partners in her life. Really? I mean Really? I know I'm probably something of a statistical outlier, but I've been with that many people in a single night!

Sir and I had been talking about it for a while. First as an idle fantasy, then more seriously as we both realised the other was into the idea. We discussed everything - where we could indulge ourselves, who we would invite, and what would be involved. I told Sir I'd be willing to do anything except anal. I wanted to keep that special between the two of us.

We decided on a date two weeks away and then I left it all up to Sir to organise. A few days later he messaged me saying "We're on. 7 men, 3 women, and us, all from the list." Seeing that message suddenly made everything very real for me. This wasn't just talk, not just a shared fantasy, this was actually happening.

I shivered and noticed goosebumps on my arm and seriously considered pulling out, but then I realised something - my body wasn't reacting that way through fear, but desire. That night I was especially attentive to Sir. I mean I always try my best to be pleasing for him, but that night I pulled out all the stops.

The night in question arrived quicker than I would have believed. Sir had booked the main suite in a local hotel, known within the scene for being discreet, and paid a little extra to compensate for all the extra guests.

We arrived a couple of hours early in case any furniture needed to be moved, and to give me time to get comfortable. "You can still change your mind you know. These people are our friends and they'll understand". I looked him straight in the eye (which is something I very rarely do) and told him "I want this". He looked at me steadily for 5 seconds. I felt myself wilting inside under his gaze, but I held firm. "I want this" I said again, with more conviction. Sir seemed to think for a moment, then nodded. "OK then. There is one thing though. I won't be taking part. There's going to be a lot going on. I'll be watching to make sure nobody goes too far".

I practically melted. This was Sir's fantasy every bit as much as mine, but he was willing to pass up the experience to keep me safe. I resolved to do anything I could to make it up to him.

It wasn't long before our first guests arrived and I disappeared into the bedroom area to get ready. I heard Sir making small talk and handing out drinks as he made everyone comfortable. Once the last couple had arrived and settled in, the hum of conversation died down and I heard Sir's authoritative voice, loud and clear as though he was in the room with me. "You all know the rules already, but so that we are clear I'll go over them again. First safewords. To avoid confusion we'll all be using the same ones. Green means 'carry on'. Yellow means 'slow down' or 'not so rough'. Red means stop. To be clear, if anyone says Red, everybody stops. If you see something you think is unsafe, call Red and we can check. I will not be taking part, but I will be observing, just in case. Also, Emily will not be doing any anal tonight. If anyone 'forgets' or 'slips', they will be removed and blacklisted. Any questions?"

It was quite a speech, and if possible I worshipped him even more after hearing him lay down the law and show so explicitly that I was under his protection. Important and impressive as Sir's speech was, I couldn't help thinking it had introduced some tension and awkwardness to the room. I decided it was time to change the mood and remind everyone why we were there.

I opened the bedroom door and presented myself, completely naked apart from Sir's leather collar around my neck. I knew I looked good, particularly in the soft lighting of the suite, and I stood there for a minute, enjoying the feeling of being naked before so many people and, I admit, loving their admiring looks.

I walked over to Sir and knelt gracefully in the position he had taught me, back straight, head up, eyes down, with my knees spread wide and hands resting lightly on my thighs. Then I surprised Sir, and I think everyone else, by speaking " I want to thank Sir for arranging all of this, all of you, for me. I know he's said he won't be joining the main event, so before we start I want to express my gratitude to him"

As soon as I finished speaking, I reached up, unzipped his trousers and released his cock. I was gratified to see that he was already hard from seeing me flaunt my body, but as I put my lips around him and slid down his shaft I felt him swell even further. Part of me knew that I was putting on a show and I used every technique I knew, plus some I'd only ever seen in videos. I took him deeper than I normally would, only stopping when I began choking. I held the base of his cock with one hand, the other massaging his balls while my head bobbed forward and back as fast as I could manage. Something about that triggered him and I felt his hands in my hair pulling me on to him as he shot load after load into my mouth. Being a good girl, naturally I swallowed every last drop.

I didn't expect applause, but when I turned around and saw the row of hard cocks in front of me, that's what it felt like. Some of the men were being stroked by their partners, while others were taking matters into their own hands, so to speak. "Who's next?" I asked.

To my surprise, one of the women stood up and led me across to her partner. I immediately knelt and took him between my lips. He was thicker than Sir, but not as long and I was able to take him fully into my mouth. Someone took hold of my wrist and guided my hand to another cock, then another cock appeared in my other hand. There was someone behind me massaging my clit, so I automatically arched my back and spread my legs wider to give them better access. There were hands on my breasts, lips on my nipples, nails scraping down my back. It felt like there wasn't a part of me that wasn't being touched, manipulated and pleasured.

The rest of the night was all a bit of a blur. As one hard cock left me, it was replaced by another, or a nipple, a pair of lips or a wet pussy. There's one moment that is fixed vividly in memory. I was laying on my back on the bed, my head hanging over the side. There was someone's pussy directly above me, and I was licking their clit while someone else thrust their cock into her. Someone (maybe the same woman?) was licking my clit while another cock fucked me hard and fast, both my hands were full of cock, and lips were sucking each of my nipples.

I'd long since lost count of my orgasms, but that one was particularly intense, making my whole body buck uncontrollably. I remember hearing Sir call out "yellow". Everything slowed down instantly. Groping hands turned to soft, tender strokes, the thrusting stopped and the tongue on my clit changed to gentle kisses.

I took a moment to gather myself together, reassured that Sir was watching out for me before saying "green". I was shocked by how weak my voice sounded. It was as if I'd worn my voice out moaning and screaming in pleasure. Activities resumed, but on a less frantic level.

One by one, people dropped out, either from exhaustion or satiation, until there were just 3 of us left on the bed, me, a man and a woman. I was on my knees doggy style, while she sat in front of me, legs open and her fingers holding her pussy spread wide. With each of his thrusts, my face was pushed further onto her, fucking her with my tongue as he fucked me.

I felt her legs clamp around my head as she came and I tasted her salty sweet juices as they flooded my mouth. Soon afterwards I felt him pull out and his hot cum spraying over my back. I collapsed down on the bed where I was, completely spent and unable to move, even to clean up.

Sir was on the bed beside me, my head cradled in his lap while he gently stroked my hair. "Are you OK?" he asked me. "Yes Sir. Thank you." I wanted to kiss him, but I couldn't even move that far. I fell asleep then, my head in his lap, and a smile on my face.
