n only had a moment to wonder which hole Mistress Rachel would choose before both Dommes thrust their strap-ons into her, one into her throat and the other into her aching pussy. It was a fantasy she’d had for as long as she could remember but it still caught her off guard.

n struggled to control her gag reflex while also holding back the orgasm that had been simmering in her loins for days.

Martina moaned, “Oh, that’s nice...” as every time it hit the back of n’s throat it sent a little shock straight to her clit.

“This cunt is really tight, ” Rachel enthused. “I’m glad we saved them for a special occasion.”

Had she been able to put together anything like a coherent thought she might have realized that she was the first girl to get fucked with these custom fitted strap-ons. But focusing on the pleasure of her two Mistresses while not erupting all she could think of.

More than once a fleeting thought of just letting herself go and admitting it to her Sir and accepting His punishment. But n was far too well trained to let it go beyond a thought. But also, for the same reason, n would confess to her Sir her naughty thoughts and accept any chastisement he decided on.

A moment later, just as her throat was finally adjusting to taking the dildo without gagging, it disappeared. n was so far into her subspace that she barely noticed anything more than the feeling of disappointment. But a second after that its replacement, driven my Mistress Rachel, had taken its place. n instantly recognized the taste of her own juices that coated it and that thought alone almost made her lose control.

It had a distinctly different shape than Mistress Martina’s and n was able to much more easily take it into her throat.

That was a good thing, because behind her the other dildo was pressing against the tight ring of muscle of her rectum.

n was not worried. she regularly wore a plug back there and, at Sir’s online instruction, made herself cum while fucking herself with one of the larger ones.

The Mistress did not waste a moment and began steadily stretching that opening. The resistance was enough to set off a string small shocks to Martina’s clit that almost pushed her over the edge too.

“Which girl do you think we should ask to borrow from her Sir for her first TP?” Rachel asked, pausing with the tip of her artificial cock just far enough into n’s throat to restrict but not cut off her breathing.

The question was more to implant the thought of n experiencing her first triple penetration.

More than a few times, n had masturbated herself to massive orgasms as she pictured herself being taken and used for pleasure by three women. With only two hands though, it was impossible to move three of her dildos at the same time, so the feel of it remained a theoretical fantasy.

Sir, she knew, would surrender one of his playmates to make this dream come true.

Rachel and Martina had spit-roasted a girl more than once and were quite good at synchronizing their movements in a way that controlled their target’s pleasure. Both saw how easily n could be pushed into orgasm but had committed themselves to making sure it didn’t happen before getting her Sir’s affirmative nod.

But that did not restrict their own orgasms and after a couple of minutes they began really fucking the restrained beauty hard. It didn’t take long before Martina and then Rachel shuddered with beautiful orgasms.

n, lost in a fugue of submissive glory, was barely aware of them withdrawing and then freeing her from the stocks that held her in place and then having her body manipulated to be on her back with her body going in the other direction.

Two pairs of hands returned the three vibrators to her pussy and ass and she mentally cursed her Sir for having given them to these two women.

Once in place, her thighs were strapped with leather belts just below her hips and above her knees. Others quickly followed at her ankles and at two places on her arms, pinning them to her sides.

n heard the sound of rustling plastic and raising her head just enough saw that the sound heralded the reappearance of Hester holding a couple of thick plastic bags and a small vacuum cleaner.

Holding up the bags which were normally used to vacuum pack clothes for storage the Chef told them, “I’ve zipped the two bags together and put some heavy tape over the seam. It may not be airtight but as long as you keep the vacuum attached I’m pretty sure you can keep it snug.”

‘It was finally happening!’ thought n, the very idea almost enough to make her cum.

The three women had no problem fitting the joined bags together and putting the vacuum hole of one of them over her mouth. A plastic tube, coated with the distinct taste of Hester’s pussy was put between her lips and then the hole was sealed with tape.

“Don’t let go of that, ” Hester ordered unnecessarily.

Lost in her thoughts, n tried to picture the scene but knew that was a dangerous path when she’d been edged for so long.

The sound of the vacuum being turned on snapped her out of her revery and a moment later felt the thick material begin to contract around her strapped body. n opened her eyes but the heavy plastic made seeing anything all but impossible. Except for the blurred outlines of the three women she could make out nothing so she retreated to the darkness of closed eyes.

“If you can hear me, make a sound through the tube, ” a female voice said. Muffled, the sound’s source could not be ascertained.

n tried to say, “Yes Mistress, ” but the tube between her lips made it come out, “Eh i-i...”

The two Dominatrices smiled at each other, this was going to be fun!

“Okay, n. This is our first time together and we have no idea what your limits are...” said Martina.

“I’ll bet she can take a lot!” Rachel interjected excitedly.

“So we’re going to be cautious. And, because we hope this is just the first of many visits, we want n to feel safe, ”

n was starting to get very warm in the contracting plastic and its strong odor was dominating her senses. she was unable to tell with the moisture she felt was sweat or her own juices.

“And because you can’t talk or move, your safe word will be three grunts to stop and one long sound to stop to continue. Do you understand?”

n made a long “Unnnnhh...” sound that both women understood and were pleased by.

“Try the ’Stop’ now.”

“Unh... unh... unh...”

As a reward, Mistress Rachel pressed the button and the clit vibrator buzzed to life.

But to the bound and mummified submissive, it was pure torture. Fortunately, though the passage of time is very subjective and it felt like an eternity, it only lasted a few seconds.

n felt the two women take up positions on each side of her. she opened her eyes but burred forms was all she could make out.

The two Dommes raised theirselves on one elbow and met for a kiss right above the end of the tube. They had done this numerous times with new submissives they’d bound in a similar way, though this was the first one with a mummified one.

The two fuzzy shapes n saw were blurred to her eyes but in her imagination, clear as day. And she could tell that the one on her left had flaming red hair.

Though the two had been a couple for years, they were still very much in love and kissed frequently. But over a new girl, in a way that was completely novel, it was even more thrilling than usual.

Their soft moans were easily audible through the restrictive material and made n’s heart race.

“Swallow...”

n was a little confused but then felt saliva coming from the tube into her mouth and obeyed.

It wasn’t much and only lasted a few seconds, but it somehow emphasized n’s complete helplessness.

Arms reached across her and teased already erect nipples, something she only felt but pictured clearly in her mind.

Rachel broke off the kiss and put her lips close to n’s left ear, “Mistress Martina has gorgeous tits and her nipples are very sensitive...” she whispered as she pinched and twisted the one she’d been teasing with her long red fingernails.

n imagined that dark brown nipple and wondered what it would taste like.

In response Martina gasped and growled at her partner, “I’m going to fuck your ass so hard for that, bitch!”

Laughing, Rachel answered, “Big talk from such a little cunt.”

And in return had her own hard nipple pinched and twisted.

In their first few trysts both women had tried to Dominate the other before realizing their matched tastes. That night they went down to the hotel bar and easily seduced a pair of pretty college girls to be their lucky first victims.

(Though because of the Dommes trying to show off for each other, the two young women might have used a different word than ‘lucky’)

Now they showed their powerful attraction to each other with this sort of teasing banter.

“Get that tight ass over here and I’ll show you!” the dark-haired woman laughed.

Rachel made sure her body made lots of contact with the mummified n’s most sensitive areas as she slithered over to her other side and laid on her belly with her mouth positioned close to n’s right ear.

“Get that ass up!” she was ordered and n heard the distinctive sound of a slap.

Rachel made a cute little squeal and quickly obeyed.

And then addressed their captive in a sultry voice, “I’ll bet it’s been ages since that nice firm ass of yours has gotten the spanking I’m sure it deserves.

Sir had never spanked n, though she would probably have been okay with it. And he had definitely thought about it and masturbated while fantasizing about it. But as exciting as it would be, having n’s naked body on his lap while he reddened her skin, would be dangerously tempting.

He had pictured her there, accepting and counting and thanking him for each stinging blow while he saw her glistening juices coating the plump lips of her naked vulva.

But it was a temptation he would never succumb to and ultimately just very frustrating for them both.

n trusted her Sir enough that if he’d wanted to she’d let him. But also knew just how much his desire for her must be frustrating him. And knew, when it was silent, that he had either gone to another space or was nearby, watching and savoring his favorite possession’s bound body as he relieved himself of that lust.

And n loved the feeling of knowing just how much she was desired. Desired enough that Sir would not only respect but protect her boundaries.

Another spank and cute squeal and Mistress Rachel’s warm voice, “Neither of your Mistresses is going to let you out of this house without blistering that butt.”

Martina used her spit to lubricate the strap-on. She could have easily coated it more thoroughly with a few thrusts into her lover’s soaked cunt but knew, from long experience, that she enjoyed the slight pain of being roughly penetrated with little or no lube.

A long keening moan from the woman laying close to her told n what she saw clearly in her mind and wished she was on the receiving end of.

The woman getting deliciously fucked held the remote control to n’s three devices and with each thrust, gave one of the buttons a quick tap.

As frustrating as it might be, it made n feel like she was part of the intimate act she could feel taking place beside her.

It was a very new and VERY exciting feeling and came very close to toppling the wall of her resistance.

Rachel’s fingers found her slick lips and she began eagerly playing with her pussy as Martina picked up the pace.

On another day they might have stretched out their love-making for an hour or more. But this had been a very long day and both women, without needing to verbalize it, had decided to cum quickly.

Even n, trapped in her snug bondage and compressed on all sides, could sense what was happening.

Rachel came first with a lovely sigh and a moment later n heard her partner follow.

Her mind drifted to what it would feel like to be sandwiched between the two and having permission to cum.

She felt the women moving around and blankets being lifted and the two women snuggling up close to her beneath them.

“Lights out, ” one of them said and the room went gradually darker.

n wanted to spend more time in her fantasies but the day had been exceptionally long for her too and soon all three women were in dreamlands.
