As always a big thank you to my editor Cheer_Smartie526. I wasn't sure exactly which category this fit into, but based one where I think it will go EC seemed like the best choice. Please comment and rate the story.

Krista swiped her ID over the grey panel, a second later the lock made its distinctive click as it unlocked. She pushed the door open and heard the steady sound of the elliptical machine. She noticed the lights were on when she drove by on her way to the parking garage. Scanning the room she saw no one. All the weights were on the racks and the mats and medicine balls were neatly stacked in the corner. The room was L shaped, so the cardio equipment was not visible, and that is where the sound was coming from. After stuffing her bag into a locker in the women's dressing room she rounded the corner. Much to her satisfaction there was only one person on the equipment. She didn't know his name, even though the two of them were usually the only people that used the facility in the early morning hours.
He was at least five years younger than she was, probably more. She rarely saw him outside of the gym, and had not been able to figure out which company he worked for. She had looked over the list in the lobby several times, but it remained a mystery. One thing she was certain of was her physical attraction to him. He had recently switched to running shorts from the longer basketball style shorts, confirming her suspicion that he had very nice legs. Normally he still wore a baggy shirt that hid everything except his broad shoulders and muscular neck, but today was different. The shirt he wore today fit a little tighter, revealing the well formed physique she had hoped he possessed. She wondered if he had decided to show off or if he was just behind on doing laundry.
The treadmill whirled to life as she finished entering the specifics of her workout. She glanced over at him, today he was reading while he worked out. She had noticed some days he had headphones on, some days he watched his tablet and some days he just went all out. Those were her favorite days. It was easy to get away with staring at him when he was watching a show on his tablet, but something about him breathing hard and sweating hard turned her on. One day his shirt had been sufficiently sweat soaked to start sticking to his body. That was the day she learned he had a nice chest and a trim waist. Today was even better. His current wardrobe was a bit more revealing.
The cardio equipment was in front of the windows, and at this hour acted more like mirrors than windows. The only thing Corbin could see outside were the headlights of passing cars. He didn't mind, there was nothing outside the office that he wanted to see, but there was something inside the gym. Running on the treadmill next to him was a very attractive woman. He guessed she was at least a few years older than he was, but that was hardly a deterrent. They had never spoken, and despite his best attempts he had never managed to sync up their workout schedules. Corbin had varied the time and day of his workout, hoping to catch her walking in to the gym so he could strike up a conversation, but it never seemed to happen. Instead he always walked in when she was well into her workout, or she would saunter in while he was lost in his exercise routine. A bit of movement caught his attention. She was doing it again. He glanced up to watch her reflection as she pulled her T shirt up and wiped the sweat off her face. In the process she exposed her midriff, and it was a wonderful sight. Her skin was smooth and firm. Sometimes she pulled her shirt up enough to expose the bottom edge of her sports bra. He felt juvenile stealing glances at her, but he was unable to resist the temptation. He looked down at the display on the elliptical machine, and then his eyes drifted back up to the window to watch her breasts bounce up and down as she ran. It appeared her sports bra was not quite up to the task, or maybe there was supposed to be a certain amount of jiggle. Corbin averted his eyes again, not wanting to get an erection.
It was cute, Krista thought as she let go of her shirt, he thought she had not noticed the way he looked at her. She wondered if he had realized she was pulling her shirt up for his benefit. If she was modest she would use the small towel that she had draped over the handle of the treadmill.
For some reason they never seemed to arrive at the gym at the same time, and he didn't hang around after his workout. She looked at the readout on his machine; despite holding a pretty aggressive pace, his heart rate seemed low. She began to think of ways she could get it up.
The seconds were ticking away and soon the machine switched to the cool down stage. Corbin knew he would be done well before she would, his only satisfaction would be hearing the shower running in the women's dressing room as he left. More than once he had imagined what it would be like to walk in and watch her in the shower, to see the water flowing over her fit body. There were times she finished first, and those were the times he took cold showers so he would not be tempted to jack off to the fantasy of fucking her in the women's dressing room. He looked at her one more time, she was clearly out of his league, and then shifted his eyes back to the display on the exercise machine. The numbers paraded across the display. They were mostly satisfactory, although his heart rate wasn't dropping down as quickly as it usually did. Corbin stole one more glance at her, then turned and walked back to the men's dressing room, knowing that an ice cold spray of water was in his future.
The moment she saw him round the corner Krista began to slow down. She allowed him a full minute before her thumb mashed the cancel button and the belt on the treadmill slowed to a stop. She grabbed the small towel and wiped the sweat from her brow, then began walking towards the Men's dressing room. The door was propped open, but she could not see past the first turn. Listening carefully she could hear the soft sound of him undressing, then the clatter as he set the bottles of soap and shampoo into the shelf molded into the fiberglass shower stall. Finally the steady sound of the shower spraying against the wall filled her ears. Once she heard the shower curtain close she walked in.
The water hit his chest like icy needles. Corbin took a deep breath and lowered his head under the spray, shivering as the cold water saturated his hair. It was almost painful, but the cold water was doing what he wanted. Instead of standing up and begging for attention his cock had shriveled up, trying to conserve all the warmth it could. He followed his routine of lather, rinse, and repeat and then moved on to soaping up his body. He had the odd feeling he was being watched, but the shower curtain was closed and the dressing room was usually empty at this time.
The shower curtain was opaque and she could just make out his silhouette. Something seemed amiss, but she could not quite put her finger on it. Krista slipped her hand beneath the waistband of her shorts. The moment her finger reached her hot, wet pussy she realized what was wrong. It was cold in the dressing room. There should have been a cloud of moist air pouring out of the shower, but there wasn't. It dawned on her that he was taking a cold shower, and that only excited her more. She dipped her finger into the folds of her labia and then drew the wet digit over her clit. She heard a loud clunk and noticed he was bending over, no doubt to pick up something he had dropped. The idea of him bent over in the shower encouraged her to quicken the pace at which she stroked herself. She imagined him doubled over, grabbing his ankles as she stood behind him. He would be nervous, wondering what she would command him to do next. Her free hand slid up her body until it found the sports bra's zipper and unfastened it. Her breasts tumbled out, finally free of the restrictive spandex. Seconds later she was tugging on her swollen nipple and a quiet moan escaped her lips. She heard the water stop, but she didn't care. Getting caught was part of her plan.
Still shivering Corbin opened the shower curtain to retrieve his towel. His eyes went wide at the unbelievable sight that greeted him. His nameless companion, the fixture of his fantasies, was standing there with one hand between her legs and the other on her breast. Despite being on the edge of frostbite his cock became fully erect in a matter of seconds and his jaw dropped open.
"If you want me to stay, turn around and put your hands on the wall," Krista commanded. He started to turn, but then he paused. Krista wondered what would work better, the carrot or the stick. Even with her martial arts skills she probably could not beat him if he came at her, so she thought it best to avoid a physical confrontation. It was unlikely he was familiar with the customs of being a submissive, so ordering him to do anything probably would not work. That left the carrot. A seductive smile flashed across her face, "I promise you will be happy if I stay."
