Walking swiftly down the hallway, Corbin felt his heart rate rise as he approached the door to the gym. He had noticed the lights were on when he drove in, but had not been able to tell who was using the facility. It had been almost a week since his encounter with the nameless woman that he had been lusting after. Sometimes he thought it had all been a dream, but he hoped it wasn't. He waved his ID badge in front of the grey panel. Time seemed to stand still as he waited for the door to unlock, and when it finally did he eagerly opened the door. The moment he heard the steady beat of someone running on the treadmill his cock began to swell. He had modified his wardrobe for just such a possibility, sporting loose fitting shorts and a shirt that hung well below his hips. Reaching into his pocket he pulled out his phone and scrolled through the play list as he rounded the corner.
On the treadmill his fantasy woman was running at a fast pace. He watched her breasts bounce up and down with each step. He felt like he had license for more than a quick glance since she had watched him masturbate in the shower, but averted his eyes after a few seconds. She looked at him and smiled, then pulled her shirt up and wiped the sweat off her face. Without a word she released the shirt and continued her workout.
The change in his outfit was understandable and flattering, but still a bit of a disappointment. She could not really blame him for getting an erection, or from hiding it. It was an unfortunate rule of society that unlike swollen nipples poking through a tee shirt or blouse, a bulging crotch was not something to be admired. She wrote it off to his youth and inexperience. Training him to control his body was something she was confident she could accomplish.
Walking past the elliptical machine Corbin stopped at the stationary bike, which was on the other side of the treadmill. He wondered if his erection would fade away once he started his workout. He looked at her tits again, hoping to see some sign of arousal, but either the material of her sports bra was too thick, or she didn't have the tell tale sign he was looking for.
"Hi," Corbin said as he settled on to the bike, not sure if she heard him over the noise of the treadmill.
She turned when he spoke and replied, "Hello," then resumed her workout.
Corbin was confused, not sure if she was being a tease or just being discreet. He pushed down with his leg, the panel on the bike lit up and he began to enter the information it requested. Less than a minute later he had started his workout. He continued to glance up and look at her reflection in the windows, hoping to catch her looking back at him, but she seemed focused on her workout.
As her feet pounded against the treadmill Krista stole a few quick glances at him. His wardrobe was much less revealing, but she had not forgotten what he looked like naked. The only portion of his anatomy that wasn't covered by baggy clothing were his arms. They looked strong and powerful, and combined with his bushy blonde beard and shaggy hair he looked like a lumberjack or a Viking. His physique was certainly a big part of why she found him attractive, but not just because he would make a delicious piece of arm candy. Krista found being in control of someone that was physically stronger than herself was a special thrill. She noticed he had increased the intensity of his workout, and wondered if this was what he had planned or if he was trying to shorten his routine so that they would be finished around the same time. If that was true, she wondered if he would try to match her pace in more intimate physical activities.
The lights on the display showed that he was near the maximum recommended heart rate, but his erection refused to go away. Corbin had done everything he could think of to lessen his arousal. He had stopped looking at her, stopped thinking about her and pushed his body to its limits. Sweat covered his body and he was almost gasping for breath. He tapped the button on the machine to ratchet the resistance up to the next level, but his cock continued to take more than its fair share of his blood supply.
Krista's eyes were drawn to the one other bit of exposed flesh on his body, his lower legs. They were almost a blur as they whirled around and around, but they looked good. On each down stroke the calf muscle flared out, and then relaxed as his leg coasted through the upper arc of the pedaling motion. The baggy clothing would have to go, she decided. He would simply have to find another way to deal with the side effects of her presence in the gym.
The message flashed across the display "HEART RATE EXCEEDED -- ENTERING COOL DOWN" and he felt the resistance drop off dramatically. He flung his head back and slowed down his legs, taking some comfort in the fact that she would be the only one to see him walk to the dressing room with a hard on. He wondered if she would follow him again if the dressing room remained empty. When the numbers showed his heart rate had returned to normal he stood up. Even though the muscles he had pushed to the breaking point were not the ones he needed for walking his legs still felt a bit wobbly. He turned to see her still jogging on the treadmill, her T shirt was wet with sweat and plastered against what he imagined was the exposed skin on top of her breasts. He nodded politely as he walked by on the way to the dressing room and another cold shower.
What finally caused his erection to falter was the sound of the shower. Not his shower, but one of the other stalls. He heard it the minute he walked into the men's dressing room. He guessed it was either one of the guys that commuted in on a bike or an early morning runner. Either way it meant he probably wasn't going to get a visitor this time, much to his disappointment. Corbin peeled off his sweat soaked clothing, wondering how he was going to keep his cock under control when he saw her again. His cock jerked.
"Down boy," he mumbled to himself, then realized he was standing complete naked and had not even taken his towel out of the gym bag. Shaking his head he started to play catch up with his routine. Normally he put his soap and shampoo in the shower first, and then he would turn on the water, then hang his towel and finally get undressed. She had his entire world in a tailspin. After putting the towel on the hook by the shower, he dug the two bottles out of his bag and stepped into the stall. At least the water was warm this time.
As she loitered at the entrance to the men's dressing room Krista considered her options the sound of water running had greeted her when she approached the door, but just before she set foot inside she heard a second shower turn on. He wasn't alone this time, so she wouldn't be able to repeat what she had done last time. It would be easy enough to get herself off in the women's shower, but that wasn't what she wanted. A more daring plan popped into her head. She pulled her phone out of the sleeve that held it against her upper arm and began to tap on the screen. If she encountered anyone, she would just explain she had been distracted at taking a wrong turn. The two dressing rooms were mirror images of each other. Unlike a man wandering into the women's locker room she would not seem like a pervert or a threat, just an air headed bimbo that could not walk and text at the same time.
Secure in the privacy provided by the shower curtain Corbin let his mind wander again. His fantasy had not expanded past what had happened almost a week ago. He was still fixated on the image of her with one hand on her pussy and the other on her breast. He tried to imagine what she looked like naked. A variety of images cascaded through his head. He knew roughly what she looked like, but there were endless details to sort out. Did she shave her pussy, and how much? How big were her nipples? Were her breasts natural or did she have a boob job? As he fine tuned his mental image of her the temptation to stroke his cock began to grow.
Another complication had arisen. It appeared that her playmate was not taking a cold shower today, as clouds of steam billowed out of both shower stalls. Krista shook her head when she noticed that the two stalls in use were at the opposite ends of the room. What was it about men that made them want to be as far apart as possible when they were naked? She pondered her situation, wondering if she should choose curtain number one or curtain number five. She had seen the other men that used the gym, and had no desire to see most of them naked. She paced back and forth, looking at the blurry silhouettes behind the curtain, trying to decide which one to choose. Then she saw something and knew exactly what she was going to do.
Corbin was conflicted. He had never even pissed in the shower and he was thinking of jacking off in one. Again. He was so lost in his internal conflict that he did not noticed the shower curtain sway slightly. Suddenly something covered his eyes and he heard a familiar voice whisper in his ear.
"Guess who?"
Adrenaline surged through his body as his fight or flight instinct reacted to being startled. His brain shifted gears rapidly as his priority switched from self preservation to getting laid. He felt her body pressed against his, but stood motionless.
"Oh, you can't guess, you don't know my name," she giggled.
"I'm..." he started to say, but she clamped her hand over his mouth.
"Shh, we are not alone," she said, straining to stay on her tip toes. He was a bit taller than she was, so getting her mouth next to his ear was a struggle.
"I know," he whispered, his voice still muffled by her hand and barely audible over the shower.
"Did you take my advice on your diet?" she asked.
Corbin nodded in response. It had seemed silly, but each time a mouth-watering cheeseburger tempted him, he thought about her lips wrapped around his cock. The trick was only holding on to the thought long enough to order something healthy, but not so long as to give himself an erection.
