Eighteen knelt on the mat and waited for her next run. She'd been run ragged already and it was not even time for her midday break. All in all, Eighteen had yet to find her inner mailgirl as her fellow mailgirls referred to it. They seemed, if not content, at peace with their lot. Actually, some seemed downright happy to be collared. But Eighteen was not quite there yet. That said there were some upsides to being a collared slave.

It had been twelve weeks since she had been collared. The learning curve had been steep. Not on how to deliver messages. The bones of the job Eighteen had known before she started. After three days shadowing Six, she knew the layout of the Jersey branch of US Financial pretty well. No, the learning curve was how to survive being a mailgirl.

Quite aside from the constant humiliation, she was now experiencing first hand all the things they did to mailgirls to dehumanise them.

Sleeping on the floor tethered by her collar to an eyebolt in the ground.
Eating food from a dog bowl. Along with the vomitus disgusting canned slop they were expected to eat.
Communal toothbrushes and razors.
Having to report fully on every sexual encounter or masturbatory adventure.
Peeing in public, shitting in front of her colleagues.

All the things that had gotten her so hot and bothered when she imagined doing them to someone else.

That was another aspect of this that appalled. She still got hot and bothered. She had always known she had a kinky side. Not only had she been promiscuous but she had considered herself to be a dominatrix. Relishing in being sadistic and cruel to any pain slut that dared to step into her playroom. Now she had to accept that being on the receiving end got her off too.

Idly Eighteen rolled her tongue in her mouth. She was being inspected this dinner break. If Mistress Rei was happy she'd be joining the roster of available girls. That is mailgirls that could be used for oral sex.

The program had been rolled out the day she had been collared. Though she had not been included straight away as she had feared.

The first thing that had happened when Mistress Rei caught up with her and Six in the Mailgirl quarters was she had her hair cut. Nothing fancy. A set of clippers had been produced and her head had been shaved to a number five on top and a number one at the back and sides. Quite the jolt given her hair used to reach halfway down her back. Six had exactly the same treatment straight after.

Then she had been sent to the shower to shave off all hair below her neck. With a second-hand razor while Six and Mistress Rei watched. It had only been after she climbed out of the freezing water, (no hot, only cold showers for mailgirls) and Mistress Rei had reached down to inspect her work, that she remembered that there was another audience on the other side of the mirrored glass wall.

She could have done without that recollection just then because it made what happened next even harder. Mistress Rei produced a dildo with a sucker on the base and stuck it onto the mirrored wall at crotch height. Both she and Six were then required to demonstrate their oral technique.

Eighteen was pretty good at oral. She knew this because she had been complimented many times. Once she got over the sudden attack of stage fright, with the help of Mistress Rei's riding crop, she had no difficulty in deep throating the dildo with a steady rhythm. Six surprisingly struggled mightily, and even with vigorous encouragement from Mistress Rei, gagged loudly before collapsing to all fours to vomit.

Mistress Rei did not seem put out or vexed at this though. She simply told six to take a moment to compose herself and that she would be without Eighteen for the rest of the morning.

Then Mistress Rei clipped a leash on Eighteen and led her straight out of the main entrance to Park Place. Eighteen was too shocked to protest, as she stood bare-assed naked on the sidewalk in the sun. People on the sidewalk were quick to produce phones and she was certain the internet and twitter would be awash with pictures of her naked ass. Mistress Rei quickly hailed a cab and after the driver got over the excitement of having a mailgirl in the back of his cab they set off for the address supplied by the dominatrix.

Eighteen had struggled to comprehend what was happening to her. Less than two hours before she had a career in public relations, a nice condo in downtown Manhatten and a pretty good social life. Now she was naked, collared and leashed and being led around like a pet by a Japanese domme.

In short order, they were pulling up outside a tattoo parlour on Central Avenue. Eighteen was led in and before she grasped the import of the situation, was laying on a gurney while a piercer was snapping on a pair of latex gloves. There was no picking out of jewellery or talking things over with the piercer. He had clearly been briefed before their arrival. She had received five piercing in just fifteen minutes. Both nipples were first and set with smooth segment rings. To say that they hurt was a massive understatement. A matching ring was placed in her septum before her tongue was pierced twice. Both along the centerline, one near the tip and one further back.

The piercer was nice enough to give Eighteen a cone of ice chips, but almost as soon as he was finished it was back to the cab, and back to Park Place.

Back in the locker room Eighteen was issued with her MMU. Essentially a smartphone it was loaded only with Mailgirl apps. Worn with a velcro sleeve on her upper arm she was shown how to log into it each morning and log out again at the end of her shift. It was explained that it would track her around the building as she delivered messages and also inform her of deadline or demerits if any were issued.

She was then taught the poses she would be required to adopt. Having worked for USF for some time Eighteen thought she knew. But it was clear what she thought was correct was not up to Mistress Rei's high standards. By the time her poses were meeting the dominatrix's approval, Eighteen had several vivid welts, from an expertly wielded riding crop, across her backside.

Six was summoned once more and Mistress Rei explained that Eighteen would not be talking much due to her piercings. The two had their MMU's synced and Eighteen had then spent the rest of her first day running after Six as they served as Mailgirls. The pain in her tits and nose, as well as her tongue, meant that progress was slow at times. Each jolted step or bounced breast was painful. She started to panic about this. But, after a mumbled explanation of her woes, around her swelling tongue, Six explained no demerits were issued to tango's or their partners for the first few days.

That evening, on returning to the locker room Eighteen discovered she was not the only girl taken to the piercers. In fact, just under half the girls were sporting piercings and everyone had the same hair cut.

When all the mailgirls were back, and those who could eat had eaten, Mistress Rei had everyone tethered down while she gave them the good news about the recent rule changes. While Mistress Rei marched up and down explaining the new rules the girls were silent. Once the dominatrix had retreated to her quarters, after untethering them, they had lots to say.

Three girls had been within a few weeks of completing their contracts. So to hear that everyone was starting anew on two years was particularly devastating.

Some of the girls were actually pleased that they would be giving oral in the future. Talking animatedly about who they hoped would call for them to perform. Some were more upset about their hair and others about the piercings.

Mistress Rei had explained that the unpierced girls would be available for oral use immediately. Once the pierced girls had healed they would cover while the unpierced were pierced.

No one was going to be made available to the men until they had passed the dildo test that Eighteen had taken that morning. They had that evening to practice if they had failed today. Failing the test each morning thereafter was going to incur ten demerits.

For that reason, a small group of girls had gathered around the dildo stuck to the mirror. Eighteen had idly wondered if there was an audience on the other side of the glass. While watching the girls who could talk, and had already passed, coaching the girls who had failed.

Unsatisfactory service to clients would also incur demerits. In fact, Mistress Rei talked them through the whole process. It seemed unlikely they would have anyone take them up straight away. As any staff member had to register first and provide an up to date medical certificate prooving they were free of any STI.

Six had stayed with Eighteen through the evening. Showing her what to do and where to be. She'd even given Eighteen a hug when she had broken down and just bawled at the unfairness of it all.

What had stopped her crying though was the sound of sex. It turned out it was pretty hard to hold a pity party while two people were fucking each other stupid less than ten feet away. The amount of fucking that was going on shocked Eighteen until Six pointed out there was not much else to do.

It made a strange sort of sense. All-day these women were made to parade around an office environment nude. They were objectified, humiliated and verbally abused. They returned to the locker room at the end of their shift hot sweaty and aroused. There was no other entertainment they could either talk, fap or fuck. Most, it seemed, did all three.

Each Friday they were allowed up to the executive lounge on the second floor for what was called a bitch session. There they could drink and relax. They were still required to be in uniform, but at least there were soft seats and the opportunity to pair off and find a semi-private space for sex.

On the second day, Eighteen had joined her sisters in publicly masturbating. The morning had been a gruelling one with many runs from one side of the site to the other culminating with an exchange between the second and tenth floor. One floor to few to use the lift and so Six and Eighteen had been forced to climb nine flights of stairs five times. Eventually, they both got to retire to the mat in the centre of the second floor where unoccupied mailgirls may drink (from a dog bowl of course) and kneel in the prescribed manner until their next run.

As the two women knelt, both breathing hard and sweating harder Six cautioned her protégé to try hard not to draw attention to themselves. They were both likely to fail inspection should any member of staff take an interest in them.

At that point, the lift chimed its arrival and three young executives stepped out. One looked lost in his suit, a skinny lad still sporting some acne and an angular Adam's apple bobbed above the line of his collar. The other two were more typical of USF. Well-groomed their suits the latest cut, clearly bespoke.

One of the well-groomed lads spotted the kneeling mail girls and nudged his partner with a conspiratorial elbow. The pair regarded the back of the lanky lad as he walked away from them.

"Hey, Simon, have you used a mailgirl yet," called one of the pair.

Simon stopped and turned to look at the two beaming faces of the other men.

"Umm, no, not had the chance yet actually. It's not something I'm familiar with, to be honest."

"Well come over here and I'll give you the run down," beamed the exec.

The three approached the pair of girls. The skinny boy was clearly uncomfortable with their nudity.

"So, Simon, surely you were aware USF had mailgirls when you interviewed?"

"Every company I applied to has them, John. I can't see the point myself."

"Can't see the point. Just look at them! Who wouldn't want to work at a place with scenery like this?"

"I'm sure, but email is faster."

"Sure, but how often do you check it? We all get so many emails that important stuff could get lost in the deluge. Hence these pretty little things to carry the messages you have to read."

"I see, but it must be humiliating for them."

"No, Simon, these horny little sluts love parading their naked asses around. I mean sniff them. They both stink of sex."

Eighteen stared furiously at the mat between her knees. Praying to God or anyone that would listen that the boys did not inspect her too closely. Yet their scrutiny even now was making her wet.

The other lad, quiet until now piped up, "Hey, John, this one has got a tattoo and piercings."

"So she has... You two, inspection."

Both girls leap to their feet to assume the inspection pose or 'toes.' Both feet spread shoulder width. Hands clasped at the back of their heads and then the feet raised up on tiptoes.

"Eighteen and Six, Chad. Look up their profiles. You, Eighteen, how come you have a tattoo?"

Six spoke up before Eighteen could try and mumble past her swollen tongue, "Please, sir, Eighteen is new. Also, she is temporarily mute due to a tongue piercing."

"Eighteen, stick out your tongue, show me." Dutifully Eighteen stuck her swollen tongue out as far as she could manage.

"Grief, that looks sore. Put it away. So, Six, how come there is a mailgirl with tattoos and piercings?"

"Sir, all mailgirls are soon to be pierced. The rule on tattoos has been relaxed to aid recruitment."

"Why are you all getting pierced?"

"Sir, we are being trained to offer oral relief."

"What! Wow, Simon, it looks like these girls can now take your cherry."

Chad interrupted, "Not these two. There's a new field on their profiles. Both these girls are unavailable for fellatio. Though Six here is available for cunnilingus, so your luck is in John."

"Ha fucking ha, Chad. Six how come the change and why aren't you available?"

"Sir, I don't know why the rules have been changed. I honestly did not know it had been rolled out yet. I have yet to pass the test for fellatio, sir."

"There's a test?"

"Yes, sir."

"So how did you fail such a simple thing as sucking dick?"

"Sir, deepthroating makes me vomit."

"Wow! So to pass this test you have to be able to swallow cock?"

"Yes, sir." With eyes faced forward, Eighteen couldn't see Six. But her voice was riddled with shame and embarrassment.

"What about Eighteen here? Why can't she suck Simons' cock for him?"

"Sir, while Eighteen is very good at fellatio her unhealed piercings preclude her from service."

John chortled, "So, she's better than sucking dick than you, huh?"

"Yes, sir."

"So what's this tattoo then? It looks like a ying-yang thing but there are three parts, not two."

"Sir, I believe it is the symbol of BDSM."

"The what?"

"Sir, I think BDSM stands for Bondage, Discipline, Sadism and Masochism. Though I may have gotten the D wrong."

"Well, that's pretty fucked up. Why did they put that on her?"

"Sir, Eighteen had the tattoo before she became a mailgirl."

"Ho, ho! Did she now?" John turned his attention to Eighteen, "So you like kinky sex do you, Eighteen."

Eighteen blushed scarlet and nodded affirmation to the leering man.

"So, you like to play bondage games? Kinky boots and whips and chains, huh? Did you like dressing in all those kinky clothes made of plastic?"

Again, her face still burning, she nodded to the affirmative.

John turned to Simon, "See! USF is now recruiting sexual deviants, experts in giving head. Just to keep its loyal workforce happy. You said you couldn't see the point in mailgirls. I say you're blind."

He turned his attention back to Eighteen, "So you like playing with whips and canes do you, kinky girl?"

Six spoke up, "Sir, per Human Capital, she must be called her mailroom number."

"Yeah, yeah, don't get your titties in a twist. Answer the question, Eighteen."

Eighteen gave a brief curt nod all the while wishing the ground would open up beneath her.

"We can all help with that, can't we lads? Let's all give kinky Eighteen ten demerits each, for failing inspection. That way she's bound to get the flogging she craves from Mistress Rei!"

John pulled out his phone and even Simon, after some prompting from the other two, got out his. Soon both Eighteen's and Six's MMU's were buzzing away as the deluge of demerits arrived on the synced units.

"Now git, and have a shower the pair of you, you both stink. You have twenty minutes to meet me back in my office clean and presentable."

The two mailgirls had sprinted back to the locker room to shower. All the way down the stairs Eighteen tried to apologise to Six for the demerits.

When they got to the showers Six had grabbed Eighteen's head with both hands either side of her face.

"Shut up about the demerits," she said before pulling the tango in for a passionate kiss. "It was worth it," she declared after she broke off the kiss. Stepping back into the freezing stream of water with one hand buried in her crotch.

Back in John's office on the second floor the two once again stood on toes as he inspected their freshly scrubbed skin and reapplied make-up.

"Good enough," he admitted. "I don't know what the rules or requirements are to have you two in here sucking my dick, girls. But I promise you this. You are both going to be on your knees swallowing my cum as soon as you are eligible."

That lunch break Mistress Rei had summoned them to the flogging bench.

"Thirty demerits in one hit? You are a disgrace to the mailgirls. Six, assume the position." Six climbed aboard placing her wrists by the open cuffs of the device. As Mistress Rei secured the girl in the cuffs she continued, "Eighteen you are new and so, normally, I would not punish you for demerits earnt while still learning."

Mistress Rei stood back and flourished her riding crop, "However such a massive transgression cannot go unpunished."

The flurry of blows she then rained down on Six appalled Eighteen. Though six seemed to take the abuse stoically. When she climbed off of the bench her backside was a livid red criss-cross of welts with the odd bead of blood forming at some of the intersections.

As Eighteen climbed on after, she realised she was trembling. She could not honestly remember how many subs she had personally flogged. None of them had looked as scared as she now felt. But they had all had a safe word and her assurances that she would not harm them. Mistress Rei had given neither.

The first blow was more shock than pain but the second really hurt. She wrenched at the cuffs in a futile attempt to free her hands to protect herself. The crop kept hitting, the whistling whoosh before each blow sending terror through her veins. When it stopped she was sobbing, limp upon the bench. Her backside was aflame. Six helped her dismount once Mistress Rei had undone the cuffs.

"Come on Eighteen we have to eat now," Six had encouraged. "Gotta keep our strength up for this afternoon."

Eighteen had examined her rear in the mirror wall indifferent to who may be on the other side. Her backside was as bruised and bloody as Six's. No leniency on the new girl then.

She had shuffled over to the dog bowls with Six. Climbing down on to all fours she choked back some of the vomitus foul slop she was forced to eat since the collar had been secured about her throat.

As she swallowed another mouthful Mistress Rei stood over the pair and gloated, "At over thirty demerits this week already, it will not be removed from your contract. If either of you two gets to sixty before the week is over I will add another one on."

That evening Eighteen has stood in the shower after her shift and just like the other girls rubbed one out. She didn't care who watched. Or who heard for that matter. It had hit her while running behind Six on a run. The collar was permanent. Not just two years, but life. They would never let her go. So long as she had her looks she was going to be their plaything. She was in every meaningful way that mattered a slave. They would get their way in congress eventually. Next year or the year after her pussy and ass would be up for sale. Her contract was saleable. They had power of attorney, they could keep signing her up for more indefinitely. This was her life now. No clothes. A steel collar. A number for a name. Slavery. They no longer considered her human. She had to take pleasure where she could find it. She had to admit to herself this was all turning her on.

The next day Six had passed the fellatio test. The lunch break had been spent in John's office while Six deep throated the young exec while a kneeling Eighteen watched. Both had retreated to the locker room after. Both had masturbated furiously in the showers. That night the pair had fucked each other with an equal passion too.

The oral service had not panned out in quite the way Will Barrow had thought it would. The uptake amongst women was very large. Even married women. The mailgirls were eating a lot of extra pussy. The wives were encoraged by their husbands. Most had a phone propped up recording so hubby could watch later. Single women saw it as a safe way to take the edge off. A mailgirl was nothing. A glorified vibrator. But they recognised the mailgirls had been practising on each other since their skinny necks had been collared.

Men though were not as keen. No bloke wanted to admit they had to resort to using a mailgirl. Only older single men used the girls at first. Though there was an upswing in usage once the pierced girls started to become available. The guys could use the excuse they were curious as to the difference from their regular partner. Some married men then started using the girls too. It seemed their wives would rather they used a mailgirl than strayed off the porch.

There were exceptions though. John Andolini on the second floor was one. He made no bones that he enjoyed using mailgirls. His girlfriends could either put up or shut up. He clearly equated it with masturbating.

So twelve weeks later Eighteen rolled her tongue in her mouth and felt the bars piercing it. The original, huge, bar that had allowed for swelling had been swapped out weeks ago. What she had now, just like her collar, was a permanent fixture. If she passed inspection this lunch break she too would be available. She knew she would pass. Hell, she had been using her tongue on Six for weeks now. She had gotten pretty proficient at using the bead in the tip to drive her lover wild.

Her MMU buzzed, summoning her down to the locker room. As she jogged down the stairs she wondered if any of the feminist groups would get anywhere fighting what the mailgirls were becoming. Eighteen now had one hundred and eight weeks on her contract. It was getting longer as the demerits were becoming harder and harder to avoid. She was being whipped almost every other day now. Her ass, just like the other girls, was a constantly changing mosaic of welts and bruises.

The rumours about the new rules were rife. Matching steel cuffs to compliment the collars was an almost certainty. That some local businesses wanted mailgirls to deliver was known. Whether USF could swing public mailgirls was the only question. Mistress Rei had hinted heavily that they were soon likely to be sporting their numbers as tattoos.

As Eighteen knelt on a mat after her inspection she realized she was actually pleased to be available. Perhaps she was more of a mailgirl than she realised. Could it be she was actually happy in her collar? Her MMU buzzed. John Andolini, second floor, fallatio. 15 minutes. Mailgirl Eighteen smiled.
