Jodi is fitted with a device that will drive her to distraction. The calibration routine pushes her to her limit and beyond.


Author's note: There are a few unusual kinks touched on in here, but only in passing, not enough to justify a tag. If you happen to have an aversion to one, it's probably not enough to bother you, but I'll list them here just in case: tickling, electricity, and light pain. There's also a overarching theme of medical procedures (specifically an injection) to the series, but it's not directly discussed in this chapter.

"Congratulations, ladies, you've made it through the first round. Do that four more times, and you'll win $100,000. But with each round, the price of failure doubles. Will you make it through round two, or suffer six weeks of denial? Let's find out." Albert gave the wheel a firm pull, and the pointer began to buzz as sections went past.

The five rounds of You Bet Your Clit didn't have any official names, but the fans generally agreed to call them (in order) Athletic, Distraction, Resistance, Head-to-Head, and Challenge. Each round's challenges mostly followed that theme, with a few exceptions thrown in to keep both contestants and audience off-balance.

Round 1's "Athletic" moniker meant that most of its games were just athletic feats. They threw in a bit of sexiness to fit the show and hint at what was to come later, but the basic nature of each game would fit on a more conventional athletic competition show.

In round 2, the Distraction round, the contestants faced another physical challenge, but some element of the game would try to distract them from winning. The nature of the challenge and distraction varied from game to game, but one or the other was always overtly sexual. Most of the time, the contestants kept their clothes on.

Round 3 was where the show discarded all subtlety. Each game was designed to bring the contestants to orgasm, repeatedly. The scoring, on the other hand, rewarded not coming. Sometimes this was measured in points or penalties, sometimes the orgasm itself would delay you or set you back. Whatever the setup, it tested the contestants' Resistance to pleasure.

With only two contestants remaining, round 4 pit them Head-to-Head. Direct physical contact was common, and if the contestants were separated, the game would provide a way for them to affect each other.

The fifth and final round was the Challenge round. With no competitors left, the contestant faced off against the game itself, in an all-or-nothing challenge. Pass, and they walked home with the full prize. Fail, and they suffered the full penalty.

Jodi swallowed. On this show, success was a two-edged sword. If you were going to fail, it was best to fail early. In round 1, the worst you faced was three weeks with a numb clit and no orgasms. Now that they were in round 2, it was up to 6 weeks. And even if it was really close, penalties always went up from round to round. Since Anne had gotten a week and a half, that was the minimum penalty now. If Jodi wanted to avoid that, she had to win.

With her resolve renewed, Jodi focused on the wheel, which was slowing, slowing, and stopped.

"Looks like round 2 will be Weapons of Math Distraction. How does this one go, Sam?"

Another video started up on the monitor.

"Weapons of Math Distraction is a game of mind over matter. Six numbers and a target will appear on the screen. You will have 5 minutes to add, subtract, multiply and divide the numbers to reach the target. Each number must be used once, and only once. The closer you get, the more points you earn. But be careful: if you mess up, you get no points at all! After five puzzles, we'll tally up the points and see who won.

"Now, some people say that plain old math is, well, boring. And one of those people accidentally said so. In front of our chief engineer. He was not amused. After making some suggestions that were, frankly, anatomically impossible, he locked himself in a workshop for three days, and when he came out, he was carrying one of these.

"What appears at first glance to be a chastity belt is, in fact, a Weapon of Math Distraction. It comes equipped with two expandable dildos, twenty-seven independently-controlled vibrators, and a few other features that are, I quote, 'too complicated to explain in a three minute video, so go away and let me work', unquote.

"In any case, this addition is likely to divide our contestants' attention. Will they be able to negate it, or will it multiply the difficulty? Let's find out."

Raoul nodded to Jodi as she re-entered the changing room. He held out a hand, helping her back up onto the dais. "So, do you want to remove your panties, or should I?"

Jodi matched his deadpan tone, "I'm more worried about why you're wearing them in the first place."

He smiled. "Nerves settled down a bit now that round one is out of the way?"

She nodded. "A bit."

Raoul said, "Good. In any case, the WMD replaces your costume's panties, so one of us does need to take them off of you. Your choice."

Jodi shrugged. "Given what you're about to be fitting me with, I don't think it matters much. Go ahead."

"True enough. Okay, could I get you to grab the sides of your skirt and lift the whole thing out of my way? Perfect. Now hold still..."

With the skirt in the way, Jodi couldn't see what Raoul was doing, but she felt him run something up both of her hips, at the same time. After a brief tug, she felt the lace panties abruptly loosen and fall away in front and back, followed by Raoul pulling them from between her legs.

He looked up at her, eyes twinkling mischievously. Jodi kept her lips sealed, refusing to give him the satisfaction of asking what he'd done. She might not know the specifics, but it was clear he'd used something to cut the sides of her panties.

Raoul's smile deepened a touch anyway, then he tapped the base of the dais with a foot, and a compartment sprang open. He pulled out something that looked like a metal butterfly, with two finger-sized bubblegum-pink rods sticking out of it.

"Okay, could you separate your feet? Half a meter or so is plenty, just need room to slide this into place without pinching you. Yeah, that's plenty." Raoul walked behind her, holding the device by the inner sides of one "wing".

"Okay, I'm going to slip the back side in first. As soon as it's in all the way, it'll start to grow. This is part of the calibration routine, and also helps to anchor the belt so I don't drop it partway through. Let me know when it stops." A section of the wall in front of Jodi lit up as some unseen projector gave her a close-up view of the proceedings. She snorted, amused by the proof that someone had wanted to startle a reaction out of her with that little trick earlier.

Even knowing exactly when it was coming, it was still a bit startling when the smooth and slippery protrusion made direct contact with Jodi's asshole. She didn't quite flinch, but her legs tensed for a moment before she forced herself to relax She'd experimented with anal play a time or two, but it didn't do much for her. Even Raoul's presence couldn't salvage the experience, so she just did her best to stand still as the thin probe was slowly but firmly pushed into her.

She did jump slightly when the metal reached her ass. It was very cool to the touch. Not uncomfortable, just unexpected. The device didn't give her a chance to adjust, either, and it was... unnerving to feel the object began to extend and expand inside her butt. It wasn't fast, but she could definitely tell it was changing from moment to moment, gradually stretching her and making her feel full. Already, she felt like she needed to use the bathroom, and still it kept going, creeping further upwards and expanding still further.

And then it stopped. Right as it began to go from unfamiliar to unpleasant, the device seemed to sense that, and stopped expanding. She wasn't quite sure if it shrank a little at the end, or if she just adjusted to it, but either way, she knew it had finished. "Done."

Raoul gave the device a couple small tugs, which felt very odd, but did not move it significantly. "Good, that one's seated. Now for the front." He continued to hold the back side of the belt in place with one hand, then reached around and pulled the front through her legs, the cool metal barely brushing her lower thigh as it swung past.

The view on the screen switched to a closeup of Jodi's pussy. It looked quite neutral, the anal insertion having distracted her long enough for the rest of her arousal to fade. Staring at herself would change that before long, but Raoul didn't wait. Feeling the front dildo make contact with her sex was less startling, and just like its twin, it was well-lubricated. This side was far more to her taste, however, so she was able to enjoy the insertion even though she was only just starting to become aroused.

"Okay, same deal as before. Let me know when it's done." Raoul slid the last bit home, and the cool metal pressed against Jodi's pussy.

Just as the rear probe had done, the front one slowly became thicker and longer inside her. Jodi closed her eyes, savoring the unique sensation. The butt probe still wasn't doing anything for her, but she did have to admit that it felt... interesting as the dildo in her vagina expanded and pressed against the already-occupied space.

Bit by bit, the device grew inside her. It reminded her of the way a guy might grow inside her if he managed to stay connected after he went soft. She hadn't tried that with anyone, but the mental image hastened her nascent arousal. Jodi filed the idea away for later.

The thing felt enormous now, and just seemed to keep growing. She didn't have a solid point of reference, but Jodi strongly suspected it had surpassed her "gag gift" vibrator quite a while back. It was like someone had stuffed a baseball bat into her. Muscles she hadn't known she had were grumbling as it forced its way deeper.

And then it stopped. Just like the rear dildo, it stopped growing right as it started to become unpleasant. Between the posts in her front and rear, she wasn't sure she could close her legs now, even if Raoul suggested it. And while it had reached its maximum width, she could still feel it extending even deeper, until she jumped as it bottomed out deep inside her. It settled down again, but it was still strange to feel it just barely pressing against... well, against her cervix, she supposed.

"Okay, that one's done now, too." Jodi said it slightly reluctantly. It was a nice sort of stretched feeling, and her arousal was definitely coming back now, but she was vaguely uneasy about what might be coming next.

Raoul seemed to pick up on this. "Good, good, that's the hard part over. Well, for you at least. Now I just need to spontaneously grow a third hand, and the rest will be a breeze."

He sighed, and Jodi could see his lips pursed together in frustration. She was just about to offer to help when his eyes sprung widw open, and a wicked grin spread across his face.

"Do you know, I must have put a dozen of these things on, and I only just figured out what the Chief meant. First time I'd done one up, I complained to him that it'd be so much easier if we let the contestant lay down or give us a hand, rather than just hold their skirt. He told me that I was making it harder than it ought to be, and if I would just use my head, I'd find a better method."

With that, Raoul kneeled down on the platform, and shuffled in front of Jodi, continuing to hold the front and back of the belt in place. He disappeared under the skirt, so Jodi looked up to the monitor, trying to figure out what he was up to.

Raoul slid the hand in front up to the top of the belt, pressing it to her waist, then leaned forward and pressed his face against the front panel, pressing it tighter to Jodi's pussy.

Jodi could feel her heart beat faster. Her eyes were glued to the image, watching Raoul smirk and move his face side to side a bit, as if trying to seat himself properly. The motion made the dildo shift inside her and the metal rub against her lips slightly. She squeezed down on the dildo reflexively. Jodi might not have been fully aroused yet, but it wasn't going to take much longer!

Now that he had one hand free, Raoul used his other forearm to hold the back piece in place, and moved both hands to the clasp on her left hip. With a quiet click, that side was secured. From there, all he had to do was trade forearms, and the other clasp followed suit. After shifting his face back and forth one more time, Raoul pulled back, and looked at the completed belt.

"Yeah, much easier that way. More fun, too. You can probably tell that the belt is still a bit loose in places, but calibration will fix that shortly. Oh, I should stand up for this part."

Raoul suited actions to words, standing up in front of Jodi on the dais. She raised an eyebrow. "Calibration? I thought we already did that."

"No, no, that was just the first phase. You can let the skirt fall now, by the way."

Jodi let go and dropped her hands to her sides. "So what's the rest of it?"

"Oh, you'll figure it out in a little bit. Should be starting any moment now." He smiled at her, not a mischievous smile this time, but a happy and reassuring one. For a moment, Jodi found herself lost in that smile, the belt and the game show fading from her mind.

And then the belt... shifted.

She couldn't really describe it any other way. Even though she knew it was made of jointed metal, she could swear she felt the joints vanish, and the belt resize itself to fit her perfectly. It seemed to become snug all over, but not restrictive, as if the metal could move with her like a piece of fabric.

Jodi looked up at Raoul. Her concern must have been plain to see, but he just smiled even wider. "Here it comes."

A finger ran up Jodi's pussy lips. She looked down again. Raoul's hands were held out to the side, as if to show her that he couldn't possibly be touching her.

A pair of hands grabbed her butt and started kneading gently. The finger ran up one of her lips, and down the other. Gentle fingers slid across her shaved mound. Several fingers caressed the inside of her still-stuffed pussy.

Calibration. She looked up at him, awareness beginning to dawn. What calibration would you need for a device that tried to distract the wearer with sex? "How far?"

Raoul just grinned even wider. She nodded, understanding now why he stood up. She stepped forward, bringing her feet closer together and her chest against Raoul's. She wrapped her arms around him in a bear hug, and felt his arms close around her back. The warmth was a sharp contrast to the belt's still-cool surface. Jodi lay her head against Raoul's chest and closed her eyes.

The belt wasn't was't wasting any time. As she stepped forward, it felt like her clit was sucked through a hole and into a warm, wet pocket. The velvet-like walls of the pocket were a sharp contrast to the cool metal of the rest of the device. By the time Raoul's arms closed around her, her lips had been pulled into their own velvet slots.

The belt ran through sensations after sensation. Fingers stroked every inch covered by the belt, inside and outside. Hands kneaded at her. Feathers tickled her. Light pinches, mild shocks, slow and fast vibrations, suction, firm slaps, fingernails, cold and heat. The dildos expanded further, shrank down, pulsed rhythmically, bent, twisted, undulated, thrusted, grew bumps and rings. One after another, after another. Jodi lost track of time, unable to sort out the sensations, just leaning against Raoul and feeling.

And then it stopped. Jodi's eyes fluttered open, confused. Had she misunderstood him? He hadn't said anything, but she was sure--

Jodi's entire pussy vibrated. Clit, lips, and every inch inside shook in her own private earthquake, and her eyes slammed shut again as she began to emit short moans punctuated by quick breaths. A wave traveled from one end to the other, and velvet fingers rubbed and squeezed at her clit. Jodi held on for dear life, her legs threatening to give way. She could feel an orgasm building at breakneck speed. On her own, she might have slowed down, but the belt was merciless, driving her higher and higher. Without consciously deciding to, she shifted to the side slightly, and started to rub the front of the device against Raoul's leg. She could feel his rod pressing against her stomach as she humped his leg unashamedly. She could feel it through the belt. She knew that shouldn't be possible, but she just didn't care.

On and on it built, and Jodi continued to rub herself against Raoul. For a moment, she paid attention to how she was rubbing against his cock through his outfit, pleased by how this must feel to him, but the device pushed her further, and the thought dissolved in pure bliss. It was about to hit. She tensed further, practically a vibrator herself against Raoul's leg. Closer, closer, almost there...

And then it stopped. Jodi rubbed frantically against Raoul, but felt nothing. Desperate to come, she pulled her hands off him and prodded at the device, trying to rub through it or reach under it for that last little bit she needed to reach an amazing orgasm. She tried to pull back and look at Raoul, but he held her tight. She heard something, and it took a moment to understand what he had said. "Patience. It's not done yet."

As if the words had been a cue, Jodi felt a finger run up her pussy. A pair of hands grabbed her butt and started kneading gently. Jodi half-moaned, half-swore as she recognized the returning stimulation. The damn thing had started to demonstrate its repertoire all over again! Except this time, it paused every now and again while the device vibrated for a few seconds, keeping her near an orgasm, but not quite on the edge.

Jodi's couldn't form the thought into words, but she knew what was happening. Calibration. It was testing her reactions again, now that she was ready to come. Checking to see what worked best now that she was fully primed. She wrapped her arms around Raoul again, and humped gently at his leg, even though she couldn't feel it.

It had taken an eternity for the machine to try everything the first time. Now, with her body's reward in sight but held just out of reach, it took at least two eternities. She had no idea how it was sorting out what actions caused what reactions. She couldn't tell. It all blended together into one incredibly perplexing mishmash of sensation. Some of it felt amazing. Some of it felt icky. And at this speed, she couldn't tell the difference.

And then it stopped. She shifted, and Raoul's grip tightened a bit. "And now the finale," he rumbled.

It started slowly, gently. Exactly the opposite of what she wanted. Fingers pushed her pussy lips together, rubbing them against each other, and causing her clit to twist from side to side. Jodi didn't know if she could come this way, and the device didn't force her to find out. A finger pressed into her pussy, not extending from the dildo, but pushed in alongside it. It rubbed against her walls, directly on that spot behind her clit that Jodi couldn't ever seem to find a good angle to hit.

Her pussy vibrated again, so gently she could barely notice it if she concentrated. She was building again, crawling slowly towards the finish line she'd been staring at. But, no, that wasn't quite right. Her pleasure was still building, but it was as if someone had grabbed the finish line and started dragging it further away. The more excited she got, the more intense the pleasure, the further away her orgasm seemed to slide.

On and on it went. She couldn't tell what the belt was doing now, only that whatever it was, it felt amazing. Amazing, but not quite enough. No matter how high it built, the goal stubbornly refused to come any closer.

And then it stopped. The goal, that is. She felt it drifting closer, and the belt moved into high gear. If she had been crawling towards orgasm before, she was wearing ACME rocket skates now, and there was no stopping that chaotic rush.

She crashed into the finish line, and for just a moment, it resisted. And then she was through. All of her muscles seemed to give out, and only Raoul's firm grip held her upright. She dangled uselessly in his grip as fireworks exploded in her head. Only one part of her still seemed to work, clenching rhythmically around the wonderful rods embedded in her. The device didn't stop. If anything, it redoubled its efforts, pushing her orgasm to its limits. She felt lightheaded, and began to gasp for air, having forgotten to breathe. Every exhale was an incoherent moan.

Her eyes opened, but she couldn't focus them. Her other senses seemed to be supercharged. She could hear her own heart beating as loudly as a drum. She inhaled through her nose, savoring the earthy, spicy scent of Raoul. Her tongue rubbed uselessly against the inside of her mouth, wishing she had something to taste. She twisted her head, rubbing her cheek against Raoul's chest hair.

She closed her unfocused eyes. She didn't need them, anyway. She could see the light pulsing through her body, radiating out from her clenching walls, bouncing off her skin and creating rainbows all through her body. It seemed to have a physical presence, battering against her limbs and making them shake wildly. A warm glow was suffusing her, seeming to lift her up on a cloud.

There was a metal spring. Wound tight, and being twisted further. It shattered, and the experience redoubled. The vivid imagery faded, and her other senses seemed to dull. Her world was reduced to one small part of her body as it throbbed delightfully. With each throb, pleasure exploded through her. Some were stronger, and some weaker, but if there was a line between one set of contractions and the next, she couldn't see it. It just went on, and on, and on.

And then it slowed. The throbs grew weaker and further apart, and Jodi's body seemed to wake up, as if from a deep sleep. At last, it wound to a stop, leaving her hazy with pleasure, but gradually coming alert. She flexed her legs, and placed them back under herself, taking her weight off of Raoul's arms. His grip loosened, and she stood up straight, pushing him back gently. He pulled his arms off of her slightly, but kept them just a few inches away, clearly ready to catch her if she lost her balance. But Jodi's strength was returning, and she moved and stretched her body. At last, she stepped back out of his arms, and looked up at him.

Raoul was looking at her, but his eyes didn't quite seem to be focused. Jodi glanced down, and a smile spread across her face. "I see I wasn't the only one who enjoyed that."

He started to speak, but his voice was hoarse, and he had to clear his throat to restore it. "No, but somehow, I think you got more out of it than I did."

Her smile widened. "Quite likely. You said that you'd put on a dozen of these?"

"Thereabouts."

"Do you always come during calibration?"

"Only if the girl is my type."

"Oh? How often does that happen?"

"So far? Once."
