Karen grunted as she worked through her last set, dropping the weight with a triumphant slam as she exceeded her target rep range. She was two years removed from her Freshman Fifteen entrance into college, and had quietly worked her way into tremendous shape as she finished up her junior year at college. Karen was about 5’1”, with black hair and piercing blue eyes. Her arms had become quite toned during her pursuit of fitness, though she had managed to stop shy of the overly muscular look that frightened her so much. Her stomach was flat with the slightest hint of abs, and her legs were strong with some sexy quad definition. And, of course, her butt has become the envy of all, and the desire of most guys around her. As she worked her butt into a bigger and rounder shape, her swimsuits became more and more showy, to the point she was barely avoiding the g-string backs at the local stores. But, if you’ve got it, flaunt it, right? She had worked tirelessly for her body, and she was proud of it.

Unfortunately, Karen also had a negative, more mental aspect from so much exercise. She had created such a desirable body that she didn’t think any guy was worthy of her. When she met a nice, average guy, she felt that she deserved someone closer to a “10.” And, when she met a more jerky, handsome individual, she figured he just wanted her for sex, and stopped any situation before it could head down that road. The result was a lack of a solid relationship for over a year now, and required many nights alone in her bedroom with one toy or another. Still, she couldn’t find a balance between her sex drive and finding a suitable partner.

Besides, a lot of her time was now being consumed by different competitions. She had gotten into the occasional marathon, mud run, and anything else that could challenge her stamina. So, when she noticed a sheet on the gym’s bulletin board, she couldn’t help but be intrigued.

“The Great O Race” Karen read aloud. “Challenge your endurance unlike any race you’ve ever come across. Start time: 7:30 a.m. on Saturday morning at The L Park.”

Despite the lack of major details, Karen was still drawn to the image of a woman flexing on top of a podium. She had improved in her races, but still not enough to medal in anything. Perhaps something like this, without a lot of details, would keep the playing field low. Plus, she had been taking her training to a new level, and thought she could compete with the best of them.

She decided she would give things a shot, spending the rest of her week training hard, but not so much so as to wear her out before the big day. Her memories went back to the race she had in the bag, until the last quarter, when all her training caught up with her, and she faded fast.

Karen took extra care to hydrate herself and get a good night’s sleep before the day of the race. Then, she set off for L Park, which was within walking distance of her dorm. She dressed in a blue sports bra and tiny pink compression shorts, with a loose fitting athletic top over. She thought this outfit would allow her to deal with whatever type of course she wound up facing.

As she approached the park, Karen had increasing butterflies in her stomach. She wrote things off as nerves about the race, even though something didn’t feel right. But, she approached what appeared to be an official table, and a little of the nervousness subsided.

“Just sign up here and we’ll get you ready to go” the young man said. He was dressed in a hoodie and athletic pants.

“What kind of race is this exactly?” Karen asked as she signed her papers.

“I promise you, it’s unlike anything you’ve ever experienced” the man responded. “It’s so out there that we can’t even let you see the course until the race starts.”

“Seriously?” she asked, as he handed her a blindfold. “I don’t know about this,” she continued, reconsidering, but then she noticed the girl on the podium again. Finally, she relented, and put on the blindfold.

“I’ll lead you to the starting area” he said, grabbing her hand lightly and leading her off. Karen couldn’t see that they were quickly heading away from the park. They exited L Park grounds and started down a sidewalk heading towards a less populated part of town.

“How far away is this race?” she asked, again getting more unsure about things.

“Not too much more” he reassured, as they went down an alley way and through a missing part of a fence. Finally, they approached the intended building, and the man was careful to lead her inside without calling too much attention to what was going on.

“And…good luck” he said, giving Karen a push, sending her down a slide that had been set up in an abandoned warehouse. She screamed as she felt herself zipping along forward, managing to pull the blindfold off in time to see she was descending down a dark area. After a few more seconds, she went through a tube and landed with a thud on the basement floor. She jumped as she heard a crowd cheer, as she started to gather her bearings and look at what she was facing.

A makeshift scoreboard read “The Great O Race” in neon letters, and the board already had times up of previous contestants.

“Lauren – 16:02 (6)

Julie – 23:59 (9)

Lacey – 45:10 (18)

Jessica – DNF (?)”

Karen squinted, trying to make sense of what was on the scoreboard. Obviously, the times indicated that she was about to enter some sort of individual race to a finishing point. What in the world did the number in parenthesis mean? Could it be time penalties for missing obstacles? She had read about races where if you couldn’t finish an obstacle, you could do an alternative. Maybe here you just took an extra penalty.

She tried to look onto the course to see what she was getting into. Unfortunately, the starting point was a staircase, so she couldn’t see much. She did notice there seemed to be individuals walking around up there. She also heard buzzing in the background. But, before she could think of anything else, there was a few beeps and the clock started. Karen was scared, but she was driven forward by the thought of that podium.

She quickly raced up the stairs and pushed her way through a door, and some of the audience let out a cheer. As Karen entered the first room, she noticed a huge vibrating mass that had no path around it. She shrugged and climbed onto the bed-esque material and crawled her way through it. The whole thing vibrated like crazy, sending a tingle up her spine as she made her way across. She finally succeeded and pushed her way through the next door.

Karen couldn’t help but smirk when she took in her next room, and noticed nothing but a small jump in her path. She took a few steps and leapt over the small wall, but literally froze in her tracks when her feet stopped moving. She fell forward but straightened back out, only to realize she was stuck on some extreme fly paper type of material. She tried to pick up her feet, but there was no escape at the moment.

Karen looked up at the scoreboard and noticed a one minute counter had started, and her time had stopped. “This is a weird obstacle, but at least they stopped the clock. But why don’t I have a number yet? Isn’t this an obstacle fail?” she wondered to herself. Little did she realize that a man was approaching behind her with a vibrating wand in hand. Before enough noise hit to turn around, the vibrator was turned onto half speed and shoved between Karen’s legs.

“What the fuck?!” she screeched as the vibrating toy went off between her legs. “Get away from me. I quit” she said, flailing her arms as her feet remained glued. The man didn’t say anything, but instead turned the vibrator up to a higher speed. “What kind of perverts are you?!” she screamed as the crowd started to cheer. Despite her angry protests, nothing was changing, except the buzz between her legs was getting stronger. “Fucking stop!” she said, a bit more breathlessly now as she saw the scoreboard count down her time to 20 seconds. Her shorts and underwear provided just enough protection from the buzz, and as the pleasure started to become more noticeable, the counter went off, and the man quickly retreated into a locked room. Karen went back to the previous door, but it was locked. There was no sign of the man, and with big walls on the sides, her only option was to move forward.

She nervously pushed through the next door and faced down her next challenge. This time, a different man was waiting for her, and she yelped when she saw him.

“Don’t fucking try anything. I will hurt you” she said. He didn’t respond, but started to walk towards her. She screamed and ran around him, flying through the room at a quick pace, before tripping over a stretched wire a few inches off the ground. Before she could shake off her impact with the ground, she was caught by this level’s foe. She shook and screamed but was surprised when all he did was pull off her loose shirt. Then, he left, and she was allowed to continue in her sports bra and small shorts.

“Fucking perverts” she muttered as she pushed through to the next room. The crowd was getting restless, as Karen’s “number” remained at zero as she continued. Upon entering the next room, Karen could hear audible buzzing again, and noticed some kind of sex toy in the corner of the room. She had watched enough porn to identify it as a sybian, which had a vibrating dildo, as well as other vibrating parts to stimulate more. As she tried to work her way through a small maze, two men came at her from opposite sides. She tried to fight, but although they were seemingly emotionless, they were also strong. She was gathered up and lifted off the floor, screaming and flailing as they brought her over to the sybian. The one not holding her pulled off her sports bra, revealing her perky small C cups, and then removed her shorts and underwear together, revealing her shaven pussy, and famous ass.

The crowd roared as they brought Karen to the machine. One held her body in place while the other worked on spreading her legs. She did everything she could to avoid the toy, as the dildo poked around her inner thighs, before finally hitting its mark, and sliding deep into her pussy. Karen was forced down hard onto the sybian, and as the toy buzzed away deep inside her, the front portion vibrated against her clit. Few porn stars could resist cumming on this device, and it wasn’t long before Karen was shaking and screaming.

“You’re fucking sick” she said, on the verge of tears as her breathing intensified. She tried to wriggle out of the holds, but she couldn’t. She tried to take her mind elsewhere, but the mind numbing pleasure was unlike anything she had ever felt. She shrieked and her body spasmed. Her stomach muscles started to ripple in contractions as she lost her fight, cumming hard on the sybian. Her whole body went temporarily limp as she shook and bucked against the machine. The crowd went wild and a (1) appeared next to her increasing time. The Great O Race.

The grip on her body was relaxed when she went limp, figuring she was in for multiple bouts. However, Karen was strong, and she seized the opportunity to violently wrestle away, slipping off the toy and away from the grip, and pushing through the next doors. Her gorgeous naked body was now on display for the rest of this event, as she was met by another man. She did as she did the first time, running around him as fast as she could, keeping a close eye on the floor to watch for any wire traps. As she neared the door, a gigantic fan descended from the roof and went on full blast. Karen tried to run through it, but her progress had been halted, and her foe caught up to her. He tackled her to the floor and put his weight on top of her. She pushed and punched at him, but only had so much movement of her pinned upper body as his hand quickly wormed its way between her legs. She tried to squeeze them as tightly together as possible, but eventually his fingers slipped in. She screamed again as she was finger fucked, writhing to try to escape as his fingers quickly curled to her g-spot, rubbing mercilessly against it.

“Fuck, stop it you fucker” she panted as he fingered her expertly. “NO” she squealed as his fingers brought her closer to another orgasm. She couldn’t help but look at her foe and realize he was barely paying attention. He wasn’t taking any pleasure from this. It was almost as if he was a robot just doing a job. The whole situation made her feel sick, but there was no dulling the pleasure. She tried to push against him, but he only quickened the pace inside her. “FUCK” she screamed as she came hard, her pussy muscles rhythmically contracting and gripping around his fingers as she buck and shook. The crowd went nuts again, and her score changed to (2). She had to take a second to shake off the effects, but as she did this, the man got more intense with his finger fucks. She yelped and gripped air as he fingered her so hard that her pussy started to make squishing sounds. She had no idea what was happening, but there was nothing she could do to stop it.

“FUCKKKK!!!!!” she shrieked as she went limp. The man removed his fingers and she squirted, painting the floor in front of her with her juices. She shook uncontrollably as she tried to come down from the feeling. She had never squirted before, and this robotic man just made her. She felt even sicker than before. It gave her enough willpower to throw him off of her, and leave her trail of cum behind on the floor.

She pushed through the doors, now up to a (3) by her name on the scoreboard. This room again seemed to have little to nothing in it, but two more foes quickly made their way into the room. She tried to run through them, but this time she wasn’t fast enough. One wrestled her back down to the ground while the quickly spread her legs. This time he went in mouth first and started to lick and suck on her clit. Over the years, Karen hadn’t had very many guys who were good at oral, so she didn’t know how it could make her feel.

“I will not cum for your fucking game anymore” she said through gritted teeth as she was licked. The higher foe started to play with her tits, twisting and pinching her nipples as he held her in place while the one between her legs inserted a finger back inside her pussy while sucking hard on her clit. The pleasure quickly amped up inside her again as she tried to fight the pleasure. However, this time the pleasure was three times what it was last time, with sensations on her nipples, clit, as well as inside her, which had already made her squirt.

“NO” she shook her head back and forth, but her mouth opened and her body started to convulse again. She didn’t squirt this time, but her stomach muscles ripped and she came hard against all the pleasure on her body. She went limp again after her orgasm, the recovery period taking a bit longer each time now.

“Make her squirt! Make her squirt!” the audience started to chant, and the foe between her legs did just as the first one did.

“No. NO NO NO. Don’t you fucking dare. Don’t do that again” she pleaded but a second finger was added inside her pussy and started to finger fuck her at a crazy fast pace. Her pussy started to squish again and she felt that previous feeling rushing back on. She screamed as she went limp, fingers moving out of her pussy but tongue still against her clit. That set off a much more powerful squirt than the first time, and her cum shot all over his face. She had been brought to another multiple orgasm by these robotic men, and she couldn’t believe it.

What was worse was that her energy was being depleted during each orgasm. Her number had now reached (5), and she was having trouble finding the strength to go on. But, when the foe between her legs took off his bottoms, exposing his cock, she shouted at the top of her lungs and kicked constantly to keep him away. It seemed she might have a chance to fight him off until two more foes were released into the room. They quickly took a hold of each of her legs, spreading her wide open. Before she could protest, he moved into position, and barreled his full length inside her.

“You sons of fucking bitches” she said with tears as he started to fuck her. There was still no emotion on any of the faces. The man stared blankly as he fucked her. Still, there job was to make her cum, and they soon unleashed everything they had. The one holding her body went back to work on her tits, rolling her nipples in his fingers while one of the ones holding her legs started to quickly rub her clit. The one between her legs started to fuck her deep and powerfully, making her body bounce beneath him.

She couldn’t believe what she was facing. All of these hands on her, and now an unprotected cock fucking her. She could feel his thickness against her walls. She could feel him pulsing against her bare insides, being filled up again and again. She was horrified, but pleasure was coming at her from every angle. She made one last attempt to wrestle away, but there were simply too many hands on her. She screamed as she came again, her tight pussy going off in spasms around the unprotected cock inside her. Her body inevitably lost its energy again, and the crowd demanded their multi orgasm show. The two holding her legs spread her wider, one putting even more pressure on her clit, fingers blurring as they rubbed like crazy. The one holding her was twisting her nipples more, and the one inside her started to really pound her, unlike anything she had ever experienced.

“FUCK YOU. AHHHHH” she squealed as the multi orgasm got the best of her again, and her juices squirted on his cock. He pulled out just enough to let the audience see her cum shoot out, and then he burrowed back in, hitting her gspot once again without mercy. She couldn’t believe nobody was stopping. The pressure on her clit was constant. Her nipples were never left alone. The cock inside her wouldn’t stop fucking jackhammering away. And now, she could feel the cock getting thicker and stiffer inside her.

“Don’t you dare cum in me. I will fucking kill you all” she said, as she her pleasure senses were taken to the limit again. But, again, there was no reaction. The fucking did stop though as he shot his hot cum inside her. One more dirty trick to make her cum again. Despite the horror of the situation, the constant pressure on her sensitive body was now met by spurt after spurt of hot cum inside her. It was too much and she was held in place as she came again, body shaking violently, beautiful stomach muscles rippling as she came hard on the bare cock that was filling her with more hot cum than she thought possible.

And just like that, they all stopped. She looked up at the scoreboard.

“Karen – 14:32 (8)”

She was in first. She was also embarrassed that thought crossed her mind as she laid there with a mixture of his and her cum leaking from her pussy.
