Mewtwo pushed open the metallic door that read "Stair access". She instantly felt a chilly draft brush against her chest. In this building, stairwells were devoid of AC because they were hardly ever used by anyone. As a result, they were nearing the outside temperature on this cold, rainy, autumn day.

"Well, better get going. I'd have taken the elevator but...yeah, I don't feel like getting stuck in one today of all days...I can use the exercise anyway. These Poképuffs snacks are getting to my hips anyway."

She took a deep breath and started lightly jogging up the first few flights of stairs. Time was of the essence here. She would not miss that drone delivery. She couldn't afford it after what she did.

A mere two minutes after the beginning of her ascension, she started feeling a bit of discomfort in her chest. Bouncing around as they did, her breasts were not used to such rough treatment.

For the longest time, she used to wear the tightest bras she could find. She never felt at ease with the size of her breasts. Ever since she was a teen, she always had the biggest bust out of all her friends, acquaintances, teachers and colleagues, thus sparking a lot of envy and jealousy. Because she kept her assets in such tight quarters, her chest muscles never really developed, feeling strain at the slightest bounce.

She cupped her breasts in each hand and resumed her climbing.

She silently cursed this company's dress-code policy, although her own adopted the exact same rules a few weeks ago. She briefly wondered if those were mere coincidences or if some bigger scheme was involved. As far as her company was concerned, the entire male staff had been "promoted" to different offices and a new batch of cryptic yet mandatory NDAs had to be signed before that new dress-code policy went in effect. Girls from accounting also mentioned something about most of the company's stocks being bought out of nowhere a few months prior. Besides the obviously degrading new rules, operations had remained pretty much the same, with increased wages all around. Whatever their new corporate overlords were trying to achieve, they wanted them naked and they wanted them compliant...

She made a brief stop to catch her breath. It seemed she had been climbing for a while now, she couldn't be far from the roof. She could still go for a bit, but her totally ethical and professional "stress relieving session" with her colleague left her slightly weak. She looked around and spotted a golden plaque bolted to the wall. It read :

"Stairwell R Floor 34
Roof access on floor 150"

Her eyes went wide. More than 100 floors left. She bent over the railing and looked up. The structure seemed to go on forever. She couldn't even see the ceiling at this distance.

She closed her eyes and focused. A blue aura surrounded her body and she started slowly levitating, a few inches off the ground. The pit between the stairs was too narrow for her to fly directly upwards but going the normal way without actually walking would definitely save her some time and not leave her completely exhausted.

Or so she hoped...

After only skipping a dozen floors that way, her powers faltered and she almost fell flat on her belly. She caught herself at the last second, grabbing the ramp with a shaking arm.

"Oh come on...We didn't do it for THAT long..." she tried to recall how many hours she spent with Milie down there.

"Okay, maybe we went at it for a while...a long while..."

She sighed.

"And that little psychic outburst at the end didn't help either" she shamefully remembered. Looks like she was stuck doing things the old fashioned way.

As she forcefully pressed on, her legs felt heavier. The cold air was stinging her lungs even though each sharp breath didn't help cool her sweating body any.

She eventually collapsed at floor 63, utterly exhausted. Her cheeks were on fire and her eyes watery. She laid there for a few minutes, her breasts frantically raising and lowering to the rhythm of her gasping breath. After struggling, she finally managed to sit upright. She was damp with sweat. She felt the cold concrete beneath her through the fabric of her clothes. She needed to cool off.

She pulled her skirt up and slid her panties down to her knees. She rested her naked buttocks on the cold and hard surface. She removed her shoes, tossed them behind her and laid her legs flat against the ground. Her crotch also felt a little too hot for her taste. She tried to spread her legs but her panties prevented it. Annoyed, she pushed them all the way down to her ankles before exposing her nether regions. As her lower-body was slowly cooling down, her top was still trapping much of the heat.

She undid her tie and all of her buttons. The fabric lazily slid down her shoulders and back. She exposed as much skin as possible while still keeping her clothes on. She checked her pockets for any tissue to wipe her forehead with, but found none.

"Must be in my briefcase..." she thought.

She couldn't just use one of her sleeves either. This was her only suit for the day and if they were to hand the papers to the upper management tonight, said suit needed to remain as clean as possible. She was lucky enough the milk stains her colleague left earlier were mostly on the inside of the suit.

She reported her attention on the bright red piece of fabric around her ankles. Her panties...Maybe she could use that instead ? They were made of cotton after all.

She grabbed her undergarment and dabbed her forehead and cheeks with it. The unique scent of Milie came to her nostrils. Lost in the moment, she pressed the crimson fabric against her nose and took long, slow sniffs. She briefly examined it, only to realize it wasn't hers.

They looked fairly similar, were about the same size and color, but the lace was different. They must have mixed their underwear after extensively using the sprinklers testing system in the basement...Already, her free hand was massaging her breasts while her tail was pressing against her womanhood. The smell was almost hypnotizing. Images of Milie's naked body were dancing in her head. She imagined her using her laptop, recording compromising begging footage.

"Hmm...I hope she doesn't delete the video after she send it..."

She began suckling on the fabric.

"Let's just hope we can get these papers before it's too l..."

Then it clicked. Her eyes shot open. There she was, masturbating to the thoughts of her colleague with whom she just had hours and hours of contract-terminating sex while she was supposed to hurry to the roof of the building, still dozens and dozens of floors above her.

"Wait...What am I doing ? I don't have time for this !"

With renewed energy, she scrambled up and bolted upstairs. Her skirt was all rolled up and covering pretty much nothing, her jacket was almost down to wrist level, she was holding her tie and borrowed panties in one hand, holding her bust with the other, she forgot her shoes ...But she didn't care. No more distractions, no more time wasted.

She kept climbing flights of stairs upon flights of stairs. At one point, the building speakers system began playing some strange music

(https://www.youtube.com/watch?v=A6lgVyq2xnk)

She didn't exactly recognize it, but she thought she heard it somewhere before. Despite not knowing this song, she had the sneaking suspicion that someone, somewhere was mocking her.

Her throat was dry, her tongue was drooling, after reaching floor 100, her legs gave up and she continued climbing on all fours. 110, 120, 130...She was crawling at this point, her chest rubbing and bumping against the clean but coarse concrete edge of each step.

With moans of exhaustion, she finally reached the final floor. The door leading outside had been left open, which explained the chilly temperature. The rain was still pouring outside. After collecting herself, she leaned against the door frame.

"I hope I'm not too..."

Halfway through her sentence, she heard a buzzing sound outside. She saw a small yellow quadcopter drone with white markings on it.

"Authentication required to complete delivery. Please identify requested content." asked a robotic voice, coming from some module inside the drone.

"Uuh...Merger papers, about 450 pages. Order placed by Miss Milie Prower." she stammered.

The drone remained silent for a few second.

"Please let me have it, please don't fly away." she thought.

"Thank you for using our service. Releasing cargo."

The drone dropped a small, rectangular, plastic container on the ground and disappeared into the dark sky.

Mewtwo bent down and picked up the capsule. Going back inside, she opened it, carefully avoiding to spill any water from her dripping wet body on it and was greeted by a pristine, perfectly printed page that read in capital letters "MERGER AGREEMENT".

She fell on her knees, a smile on her face.

"Yes."
