"Strip."
I hurriedly removed my jacket as the female sub across from me did the same. She was a good 8 inches shorter than my 6'0 but curvy and cute with wavy strawberry blonde hair and a smattering of freckles. We'd never met before tonight but we were both playmates (playthings?) of the same Mistress who'd simply introduced us to each other as "Sub" (me) and "Subby" (her).
Underneath my jacket was a backless pair of tight leather fetish briefs, leather ankle and wrist cuffs, and a leather collar. Subby had matching cuffs and a collar but was wearing a stringy leather harness that exposed the entirety of her tits and pussy, to my delight.
Mistress was the only one appropriately dressed for an upscale NYE party in intimidating heels and a tight black dress. Her signature accessory was a black riding crop she carried on a loop around her right wrist. She clipped leashes onto both of our collars and tugged us along behind her as she set off at a brisk pace into the building. As we descended down dark stairs into the dungeon my heart began pounding and I broke into a cold sweat at the prospect of attending my first BDSM party. I was so exposed and so under someone else's control, feelings I loved in the privacy of our respective homes that now felt shameful and intimidating in front of others.
To my surprise I felt a warm pressure on my hand and realized Subby was giving me a reassuring squeeze. I wasn't sure how she felt about sharing Mistress but if she had any reservations or jealousy she was putting those feelings behind an encouraging wall of submissive solidarity. Gratefully, I took a deep breath and started to regain my composure.
There were perhaps ten other mistresses in the poorly lit dungeon, each with at least one collared submissive. A few lucky mistresses like my own had two. About half the subs were men and the other half women. Per party rules there were no unattended S-types or unaccompanied Mistresses.
Mistress clearly knew most of these women well and was well liked within their group. Subby and I were ignored as we trailed after her, watching her make one greeting and NYE wish after another as she confidently worked the room. As she stopped each time Subby showed me to kneel, with my head down, behind her. Finally she started talking to another domme, a shorter blonde in a latex catsuit with her hair pulled back in a tight and intimidating ponytail, for longer than the others. From the few terms I could overhear: "bratty", "pain-slut", and "disobedient whore" they were discussing at least one of us submissives, and not in a positive way. I glanced behind the blonde and saw her sub, a towering male specimen, middle-aged and completely bald.
After more rapid discussion and some whispering Mistress tugged me up from behind her then leaned down to speak to me.
"I'm going to loan you to Miss Grace here while I take a crack or two at helping her tame her new sub. She knows your safeword and your hard limits and she'll take good care of you until it's time to trade back. But before you go, bend over," she instructed.
I obediently reached down towards my toes and felt mistress work a firm silicon butt plug into my tight ass. Fortunately she lubed it up before pressing it against my hole because it was slick and slid easily to the base despite its girthy size.
"With your ass plugged and your dick in that leather pouch you shouldn't be able to get into too much trouble without me," she teased. "But if Grace wants to use your tongue you should know that's fine with me."
Then she squeezed my groin and the next thing I knew a complete stranger was holding my leash.
"Come along boy, we need to find somewhere safe to store you while I make a trip to the little Mistresses' room."
I obediently followed Mistress Grace to a stockade at the edge of the room, facing inward to afford me a good look at the rest of the party. She raised the upper bar, had me set my head and arms in, then closed the contraption around me and pinned it together with a metal insert.
"I'll be back in no time, no one else here will touch you without permission from your mistress."
Speaking of my mistress I could see her across the room, tying her new muscle-bound lothario to a St. Andrew's cross. She had obtained a very painful looking single tailed whip from somewhere and was about to start what I jealously hoped was an extremely unpleasant beating.
Even across the room I could clearly hear the snap and crack of her whip against his flesh as she began plying it across his restrained physique. It was surreal seeing her in action from this third-party view, we'd only ever played before alone and I'd never truly gotten to appreciate her as an observer. Her motions were so seductively smooth, so confident, and so incredibly intimidating my cock throbbed at the knowledge that she was here tonight with me. Well, me and Subby, not that I minded another beautiful woman being in the mix.
Speaking of Subby, she was kneeling near mistress, her leash tied to a loop in the wall, safely out of range of the whip. Even across the dungeon I could see how wide her eyes were as she witnessed the ferocity with which our Mistress laid into another sub. I guess Mistress has never punished Subby nearly that severely either.
I was so enthralled by the scene that I didn't hear Mistress Grace return until I felt her hand pat the plug in my ass.
"Enjoying the show?"
"Yes Miss Grace, your sub is taking a real beating over there," I responded daringly.
"Don't worry, he deserves it," she replied cooly. "I hear that you, on the other hand, are the very model of an obedient and well behaved boy."
"I do my best to please my Mistress," I replied proudly.
"Well that's good to hear but I find that even the most obedient subs can sometimes be very naughty," her hand had stopped pressing against my plug and slid down against the leather confines of my briefs. She began squeezing and rubbing my erection as she spoke.
"For instance right now, are you aroused by your Mistress disciplining another sub or by another mistress fondling your boy parts?" she asked innocently.
I suspected there wasn't a right answer but if there's one thing I've learned as a submissive it's that honesty is always the best policy.
"Both Miss Grace," I admitted.
"Use full sentences, slut!" she admonished with a hard squeeze.
"I'm aroused by both you and my Mistress, Miss Grace," I tried.
"Well that's very naughty of you, isn't it?" the blonde dominatrix purred as she continued rubbing my erection through the tight leather pocket of my fetish briefs.
