Karen was a demon on top of the underworld. She stood at the window of her luxury penthouse and looked down at the lost souls of the damned burn in the fire pits of Hell. Karen absolutely loved her job. She turned her back to the city of Hell and made her way to over to the large mirror displayed in her living room. She was an incredibly vain demon. With a flick of her wrist, she admired her perfectly styled, shoulder length silver hair. Her long, black horns pointed straight up from her head, which gave her an intimidating look. Karen ran her middle finger down across her face, infatuated with her own beauty. She chose to have pale flesh, as to blend in with the humans she had to deal with upstairs. Her lips curled into a literal devilish grin as she admired her blood red lips that matched her eye color. Karen took a step back to admire the rest of her figure. She wore a slimming, pinstripe suit that added to the powerful image her horns established from the top. It did hide her figure, but as one who deals with soul contracts, looking powerful was her number one priority.

That's when her admiration for her own image was interrupted by the sound of a doorbell. Karen's grin swiftly cringed into an irritated frown as she wasn't expecting any visitors. She turned on her heels and made her way to the door. Practically ripping the door open, you could see the fumes of anger emit from the very sharp points of her horns. She looked from side to side, down to each end of the hallway, but found nothing. However, she decided to look down and found a quivering mail imp, holding a very important looking letter. Karen promptly snatched the letter from the imp's hand and slammed the door behind her.

 This was clearly no ordinary letter, she thought to herself, it had the seal from the big guy himself. Karen took an ancient ceremonial dagger from the side table next to her door and used it to carefully open the mysterious letter. She slipped the note out of the envelope and began to read it. It bluntly said:

"Karen,

You are being transferred from soul sales to succubus duty, effectively immediately.

The Big Guy Himself"

Karen lowered the letter and let out a disgruntled snarl before vanishing completely in a flourish of red smoke. The next thing she knew, she was in the streets of downtown Hell, surrounded by various passing by demonic entities that paid no mind to her sudden appearance. Karen crumpled the letter in her hand and tossed it over her shoulder. She decided to look up to see the location she has been summoned. In big neon lights against the blackened abyss where one would expect a sky, she read the sign "Hell's Spa". Karen took in a big breath of air and followed it with a very exhausted sigh, she made her way inside the supposed spa.

The inside of the spa was just as tacky as the outside. Neon lights continued to be a theme as the walls were lined with them. Various designs like flames and dragons decorated every wall around her. Karen rolled her eyes and set her sights at the demon girl sitting at the front desk. She was busy with computer work, eagerly typing away, as if she actually enjoyed her job or something.

Karen let out a not so subtle clearing of her throat to get the desk girl's attention. The perky demon let out a gasp and turned towards the frustrated business demon at the door. "Oh I'm so sorry ma'am!" the desk girl exclaimed. "Welcome to Hell's Spa! How may we be of assistance today?"

Karen let out another sigh and growled under breath. "I have an appointment... for Karen"

"Oh! Karen! It's an honor to meet you in person!" The young demon left her position from the desk to bow to her new guest. "If you can just follow me into..."

In another sudden puff of smoke, the two were transported to an entirely different room. Karen was standing up right against the wall of a very clinical looking room while the desk girl was standing in front of her with a clipboard. "...into the back so we can take some measurements!"

With a quick snap of the desk girl's fingers, Karen's once proudly designed business suit was stripped from her body. Now the high powered demon woman stood in her black lingerie. She wore a very lacy bra and thong set with a matching garter and stockings, along with her black stilettos which she swore she wasn't even wearing before all this started. "And if you don't mind let me just..." The perky young demon went into a very intimate range of Karen. She took an old fashion tape measure from her pocket and started to measure the various lengths of Karen's body, all while still holding her clipboard. The girl shook her head and muttered various lines such as "this just won't do" and "we gotta fix that" to herself. Hearing such things like that frustrated Karen to no end, but she gritted her teeth and took it all.

"Alrighty, so here's the plan!" the young demon exclaimed with a bright smile. As she continued talking, various other demon employees made their way into the room, each wheeling in a cart and tray. "First, your arms are just far too toned!" The young girl reached over to Karen's shoulders and gripped onto them tightly. With little effort from a strong tug, the young demon popped Karen's arms right off her body, as if she was some sort of store mannequin, and plopped them onto one of the various trays. "We'll just sand those down to a more elegant design. You'll love it!" The demon girl with Karen's arms on her cart quickly made her exit as the lead spa girl continued on.

"Next let me just.." The spa girl reached up onto her toes and grabbed Karen by the horns. Karen made a few protesting sounds but the spa girl wasn't phased. With a strong tug, Karen's head popped right off her neck and was placed onto the next tray. "You have a gorgeous face so we won't need to do much! But there are a few tweaks here and there we think you'll appreciate!" And with that, Karen's grumbling head was wheeled out of the room.

"With that out of the way..." The spa girl continued to talk as if Karen was still present in the room. In a way she was, but not so much the bits that would be listening. "Considering your new job position, it's safe to say we really need to work on that figure!" The demon grabbed Karen (or what was left of her) by the waist and pulled upward, letting it disconnect like the past pieces. She placed that on a cart as it was wheeled away. Next she grabbed Karen's hips, this time causing two pops as they disconnected from her legs. Swiftly, she tossed each remaining piece of Karen on its own tray as the other employees wheeled them away. "And with that, my job is done for now!" the demon desk receptionist exclaimed to herself proudly.

Each of Karen's body parts were wheeled away into separate rooms. Some of them were placed in a bin of similar parts, arms in the arms bin and so on, while others got immediate attention. This was a very professional establishment, after all, and the most important parts of the most important guests got the most important treatment.

Karen's upper torso, still clad in the lacy black bra, was taken into what appeared to be a massage parlor. The spa employee in charge of this part lifted Karen's torso up off the tray and placed it gently onto a much abbreviated massage table, designed for such parts. Karen's torso rested on its back, sitting comfortably enough to nuzzle her empty shoulders into the padding. From there, the spa employee ran her hands along Karen's sides. She did this very sensually, Karen's torso could melt right there with these expert hands working at her. It didn't take long before the employee was rubbing the sides of Karen's breasts. Karen's torso didn't mind, it longed for this kind of attention as it never got it while Karen was in one piece. The employee massaged Karen's breast, which became a more forceful kneading. As the employee worked her magic, Karen's bust was noticeably increasing within her bra. The once above average cleavage Karen once had was now full and impressive. Her breasts were flooding from the sides of her now struggling bra. But, again, Karen's torso was starved for attention and loved every minute of this.

In another room, sat Karen's head. Still as annoyed as ever, Karen let this spa employee lift her by the cheeks and plopped her head on what appeared to be a salon chair, except designed for just the head. Karen could see through the mirror at the wall behind her. There appeared to be a shelf completely filled with mannequin heads, but she quickly noticed that they were the heads of other demon women in line for the treatment Karen was about to get. The spa employee grabbed Karen by one of her horns and gave it a strong twist. It took some strength to do at first, but the more she turned, the easier the horn twisted off completely. Karen sighed at the sight of her missing horn as the employee was already beginning to give its match the same treatment. The employee tossed the horns into a bin carelessly and returned her attention to Karen. She brought her fingertips to Karen's cheeks as she started to rub them together. The employee dug her fingers deep into Karen's cheeks to the point of puckering her lips comically. This went on for a minute or two, to Karen's dismay, until the employee finally released her fingers from Karen's face. Karen was shocked to see in the mirror that her lips were now a lot more plump and pillowy. Somehow during all that, Karen's once red lips were now a deep black with a shimmering gloss over them now. Karen was left in awe that the new face looking back at her in the mirror. While that was happening, the employee had already attached a new set horns onto Karen's head. They were far more round and curled forwards to give Karen a softer look. And with that finished, the employee put Karen's head back onto the tray and wheeled the cart away.

Karen's newly redesigned head was wheeled back to the previous room after some time has passed. The desk girl was standing where she originally was when all this started, wearing a brilliant smile from ear to ear. "I hope you enjoyed our specialist's work so far" she said with a familiar pep to her voice. "We were hard at work doing our best to make sure you were ready for your new position! While your head was away, we managed to put everything in order. I'm proud to present to you, the new Karen!" A puff of smoke bellowed out of thin air and cleared to reveal what was certainly Karen's body. It was still wearing the black lingerie she came in with, but now it was filled in a whole new way. The headless demon body stood with its back arched to present a fantastically new and improved bust size that challenged even the size of Karen's own head. Her arms were slender and elegant, but that wasn't the only thing that reduced in size, as Karen saw her waist was noticeably more narrow. This didn't last for long, though, as moving down her figure would show that Karen's hips got the same treatment as her torso. Even her thighs were thicker as the stockings she wore hugged around them tightly. "Well, what do you think?" The desk girl asked with a bright smile.

Karen opened her mouth to give her true feelings about all this, but it was quickly cut off by the demon desk girl. "Oh but we're not done yet!" She made her way over Karen's head lifted it up off the tray by the horns, with their new design acting as much better handles. "As per orders from the higher ups, this glorious spa day was only step one of your transition into your new position! Effective immediately, we can now begin your succubus internship! Of course, this is a two part course, in that you will be in two parts! Your head will be available to rent at one of our many part rental shops up on the surface, while the rest of you will be receiving direct training from the big guy himself!" Karen's eyes grew wide in shock by this news, her jaw dropping as she realized this was a set up from the big guy himself. Before she could say a word, the demon receptionist snapped her fingers and Karen's head vanished in a puff of smoke. "We hope you enjoy your new position!"

Some time later, at the offices of Hell's Headquarters, the big guy himself was working diligently at his desk. His office was enormous and lavish, it could pass as a resort itself, as long as you were okay with the fire and brimstone aesthetic. He was busy filling out forms regarding the the plans for future lost souls, even he had paperwork to fill out in Hell. This, however, was interrupted by the sudden opening of his office doors. His eyes escaped the paperwork on his desk to look up at the unexpected guest. There at the doorway stood a familiar body, still dressed in the barely fitting lingerie, but now covered in a sheer red robe that loosely hung onto her figure. The demon's body made a strut towards his desk as her heels echoed throughout the office.

"Ugh, Karen, is that you?" the big guy himself said under his breath as he rubbed the bridge of his nose. "I really need to fire that postman. That letter was sent eight hundred centuries ago, we dissolved the succubus branch well after that. They shouldn't be sending these letters out anymore." He let out a sigh and pointed to the other side of the office. "Just go wait over there and we'll see if we can get you a secretary job or something until we can find your head."

Karen's body made her way over to the designated spot, standing in place with several other headless demon women of similar figures. There's going to be a lot of secretaries in the building for the next few months.
