First date with MATS: the Male Aggression Tempering System.

This is my first story, let me know what you think. All characters are over 18.

----Prelude-----

In an alternate universe, the year 2010 saw the creation of MATS: the Male Aggression Tempering System. The technology was originally designed as a mandatory sentence for male sex offenders, serving as a high-tech alternative to traditional incarceration or chemical castration.

The installation of a MATS unit is a minor, outpatient procedure similar to a vasectomy. During the operation, doctors implant a small, organic microchip at the base of each testicle. Initially, these microchips paired with a handheld device capable of generating a sharp, agonizing sensation of testicular squeezing in one or both testicles—all without causing any actual physical damage to the tissue. The device was also designed to monitor external trauma, recording any physical damage to the area from a different origin, such as kicking or manual squeezing.

To calibrate the system's interface, the state utilized the most aggressive offenders to gauge the pain scale, employing female testers to administer the shocks and map out the data points from 0.0 to 10.0.

The scale of the pain is from 0.0 to 10.0.

0.0 of course being the baseline, no pain at all.

1.0 being similar to a very tight pair of underwear or a 10% strength squeeze from the testers.

2.0 - 5.0 being similar to a 20% - 90% from female testers respectfully.

6.0 being a 100% strength squeeze from the female testers.

7.0 the testers had to use full force kicks to get the results needed and resulted in about a 10% of rupture.

8.0-10 was deemed too dangerous to replicate the pain so there is nothing to compare it to. The males subjected to these levels said it was more painful than they can express with words.

A few years after the original system's implementation, MATS was opened up for commercial installation to any man who chose to undergo the surgery. The consumer version was paired with a smartphone application, allowing the user to voluntarily grant access to his implant to whomever he chose.

At first, the market consisted primarily of husbands giving access to their wives. However, the culture shifted rapidly, and men began seeking out the procedure specifically to qualify for the MATS dating app. The app's core feature granted a female user temporary access to her male date's implant for the duration of their first meeting. This design ensured that the man would remain on his best behavior, providing women with peace of mind and the absolute certainty that they could instantly disarm their date if he became aggressive.

Over the years, the app evolved beyond simple self-defense, allowing female users to assert more direct control over their dating and sex lives. Which leads us into our first story.

----Story starts----

"So, this is your first date using MATS?" Caitlyn started the conversation, her tone laced with curiosity. She was a woman in her late twenties with olive skin and a thick, hourglass figure. Standing at 5'5" and weighing 150 pounds, some might call her slightly soft or thick, but Connor thought she had the perfect body.

Connor himself was a white guy in his early thirties with a solid build and a decent, everyday handsomeness. Despite being a good-looking guy in good shape, his luck in the dating scene had been entirely nonexistent lately. Out of sheer frustration, he had finally bitten the bullet two weeks ago and gotten the MATS implant just so he could use the dating app. He had matched and chatted with a few women since then, but he’d been hesitant to actually meet up. It was a justifiable fear—giving a total stranger the power to inflict severe testicular pain at the touch of a button wasn't something to take lightly. But after a few days of texting, he had finally built up the courage to agree to a first date with Caitlyn.

"Yeah, it is," Connor replied hesitantly, snapping himself out of his thoughts and having a hard time keeping his eyes off her figure. "It’s a bit scary, giving a stranger access to something that can cause a good amount of pain."

"It's okay, I'll take good care of you. MATS should only be used when I think I might be in trouble, and you look like a nice guy," she said, noticing him checking her out. Caitlyn had already noted that Connor was a decent-looking guy himself, with a good build. "Of course, MATS can also be used for a bit of fun. But like I said, I'll take good care of you," she continued with a smile, her eyes darting down toward his crotch. If he can check me out, I can return the favor, she thought.

Connor gave a worried chuckle. "Want to get a seat at the bar?"

They had decided to meet up at a local bar and restaurant near both of their houses for their first date. The MATS app automatically connects two devices once the users are close enough to each other. For this date, Caitlyn and Connor had decided on the default setup: Caitlyn received control of Connor's MATS for one hour, with a pain limit capped at 5.0.

"Let's get a table instead. It's a bit more personal, and I would like to get to know you better," Caitlyn retorted.

"Can we get a table, please?" Connor asked the hostess.

"Of course," the hostess replied. "Just over here. I'll give you guys some privacy." She smirked at Caitlyn, having clearly overheard their conversation.

Connor and Caitlyn followed the hostess to a booth that was tucked away, three tables apart from any other guests. As they sat down across from each other, Caitlyn pulled out her phone, opened the MATS app, and placed the device on the table screen-side up. This allowed Connor to clearly see the 0.0 pain value currently displayed, right next to a countdown clock sitting at 58 minutes.

"I hope I'm not scaring or intimidating you," Connor said, looking at Caitlyn’s phone with a worried expression.

"Oh, no, not at all," she said, resting her hand near her phone. "I just bring this out now so I don't have to fumble for it if anything happens, or in case we want to have a little fun." She offered him a flirtatious smile just as the waitress walked up to their table.

"Good evening, welcome! Could I start you two off with something to drink?" the waitress asked, her eyes instantly dropping to the MATS app on display.

"Could I get a lager, please?" Connor told her.

"I'll have a White Claw," Caitlyn said.

"Of course, I'll be right back with your drinks." The waitress looked at Caitlyn’s phone again, flashing them a knowing smile.

"So, this is your first date on MATS, but have you at least tested the system out on your own?" Caitlyn asked inquisitively.

"No," Connor lied. He had tested it a little, but he'd never had the courage to go past a 1.0.

"You are such a liar," Caitlyn teased. "Are you saying you didn't test it out at all? Not even a little bit out of curiosity?"

"Well, maybe a little bit," Connor admitted, flushing. "But I was too afraid to even go up to a one."

"Maybe deep down, you want me to test it out on you, and that is why you lied to me?" Caitlyn confronted his admission with a smirk. "I think you deserve a bit of a punishment for lying to me. What do you think?"

"That's up to you," Connor replied, half-scared and half-aroused.

"Yeah, I think you deserve this," Caitlyn said. She tapped the small plus sign on her app. The pain meter shifted to 0.1.

Tap. 0.2. Tap. 0.3. Tap. 0.4.

Caitlyn watched Connor’s face after every tap until the meter finally reached 1.0. The countdown clock showed 50 minutes left. "Do you think that is enough, or should I continue?"

"I guess that is up to you. I gave you access to it so you could be fair—remember, you said you would take good care of me," Connor reminded her. "I've never tested it out to a one before, but it doesn't really hurt. Just a mild ache, really."

"I think we can leave it here for now," Caitlyn said, looking down under the table as if she could see right through the wood to where his pants were starting to stiffen.

"Here is your lager," the waitress said, setting a cold beer in front of Connor, "and your White Claw," leaving the can next to Caitlyn's phone. "Looks like someone is in a little bit of trouble?" she asked, noticing the 1.0 on the screen.

"Oh, no, we are just having a little fun with the app. But he did lie to me, so yeah, maybe he is in trouble," Caitlyn responded, smiling at Connor.

"Only a 1.0 for lying? You must really like this guy," the waitress said, chuckling. "When my boyfriend lies to me, I put his pain level on a 3 until I feel he is truly sorry. I had him at a 3 for nearly an hour once."

"Well, this is his first MATS date. I don't want to be too mean right away," Caitlyn responded, her eyes locked on Connor.

"I appreciate that," Connor said, speaking a moment too soon.

"But you're right," Caitlyn countered, turning back to the waitress. "1.0 is a little too light for lying. He does need to learn a lesson."

Caitlyn pressed the large plus button on her phone, instantly bumping the pain meter from 1.0 to 2.0. "I think we can keep him on this level until we order."

"Oh, would you like to order now?" the waitress asked quickly.

"Yes, please," Connor blurted out, visibly grimacing as the ache in his testicles shifted from a dull throb to a deeper, heavier ache.

"Oh, no, give us a minute or two. I haven't even looked at the menu yet," Caitlyn jested. "And I think Connor here needs to feel what a 2.0 feels like for a bit anyway."

"Of course, take your time." The waitress smiled and walked off.

"You know what you want already? You haven't even looked at the menu," Caitlyn teased, knowing exactly why Connor wanted to hurry the process along.

Wary of being caught in another lie, Connor played along. "No, I guess I should look at the menu first." The shock of the sudden increase was wearing off, making the 2.0 level a little easier to manage. He picked up the menu and tried to focus on the text.

"How is the 2.0 treating you?" Caitlyn asked, reading the tight lines of his facial expression.

"It doesn't feel great, but it's not too bad after the initial shock," Connor admitted honestly.

"Well, that's good. Do you think we should leave it there for the rest of the date?" Caitlyn glanced down at the app. "Only 45 minutes left."

"Umm, I guess I can handle it if that's what you think it should be at," Connor said, trying to be as politically correct as possible. He was acutely aware that she could push it up to a 5.0 at any second. "But if you wanted to put it back to zero while we ate, I would appreciate it."

"I think that's fair," Caitlyn responded. "But once we order our food, I am going to push it up to a three until the food arrives. Then I will let you eat in peace. Fair?"

Connor swallowed hard. He was terrified of moving up to a 3.0, but he wasn't sure he could endure a 2.0 for the rest of the entire date. He nodded. "I think that's fair. But I have to admit, I'm a bit scared of going to a three."

"I think you can handle it. Let me look at this menu before the waitress returns. We need to order our food so I can see how you react to a three," Caitlyn said, scanning the options. "Do you know what you want yet?"

"Yeah, I'm good," Connor said, his anxiety spiking over the inevitable level three.

"So, have you guys decided, or do you need more time?" the waitress asked, returning with her notepad.

"I would like the Caesar salad with chicken, please," Caitlyn told her.

"Cheeseburger with fries," Connor said hesitantly, hoping the brief order would speed things up.

"Sounds good," the waitress said. She looked puzzled by Connor's sudden breathlessness until she saw Caitlyn extend her hand, press the large plus button, and skyrocket the meter to a 3.0. "I'll get that right out to you guys."

"Could you wait a second, please?" Caitlyn asked the waitress. "Connor was a bit rude to you, barking his order without saying please. I think he deserves the pain level to go a little higher, what do you think?"

Seeing that the phone was already displaying a 3.0, the waitress looked at Connor with a mix of pity and amusement. "I think moving it up to 3.1 would be fair."

"You are so kind. Let's move it to a 3.2, because I think he forgot to thank you for the drinks earlier, too."

Connor opened his mouth to protest, but the waitress cut him off. "I wouldn't try to talk your way out of this, sweetie." She looked back at Caitlyn. "I think that's a very fair assessment."

Connor could only nod in agreement as the ache in his groin sharpened from a deep throb into a tight, crushing pressure.

"Let me get those orders in for you guys," the waitress said, heading toward the kitchen.

"I hope it's not too painful for you," Caitlyn said. It was a partial lie; she knew he could leave or ask to stop if he truly wanted to, but the fact that he was choosing to sit there and take it for her was a massive turn-on.

"It's pretty bad. I don't know if I can take it until our food comes," Connor admitted through a tight jaw. "I don't remember the last time my balls hurt this much."

Caitlyn let out a soft squeak of a laugh. "I'm sorry, it's just... that's the first time you've openly complained about your balls, and it was kind of cute." She leaned forward, her voice dropping. "I have to say, seeing you take this much pain for me is getting me pretty worked up."

"Pain for me, pleasure for you? Doesn't seem entirely fair, but I'm glad you're enjoying yourself," Connor managed to say, still trying to keep his composure.

"Well, no real pleasure for me yet, but I think you might be able to help me out with that if we want to continue this date," Caitlyn flirted, keeping her offer slightly cryptic, though she knew exactly what she wanted his tongue to do later.

"Aside from you being a serious pain in my balls, I think the date is going great," Connor joked, his voice straining slightly against the discomfort.

Caitlyn laughed openly. "Yeah, I can tend to be a serious pain in the balls to guys." Slipping a hand down the front of her pants, she let out a low, subtle moan. "Sorry, I couldn't help myself. You taking this pain is super sexy."

She slipped her hand back out, her fingers glistening. "Would you like a taste? A little appetizer for dessert tonight, if we keep this going?" she asked, offering her wet fingers across the table.

Connor wasn't typically a huge fan of oral sex. He had performed it on previous girlfriends, but he had never quite understood why some guys raved about it. However, that wasn't going to stop him right now—the woman literally had him by the testicles for the next 35 minutes. Leaning forward, he closed his lips around her fingers, tasting her.

"Delicious," he lied. It wasn't that he hated it, it just wasn't his favorite thing in the world.

"Oh, no," Caitlyn sighed.

"What's wrong?" he asked, fighting through the crushing sensation in his lap.

"You either don't like the taste of me, or you don't like going down on girls in general," Caitlyn said, her disappointment obvious.

Connor tried to think of a clever way to salvage the conversation, but the intense throbbing made it impossible to think quickly. "Yeah, I don't usually go down on my girlfriends a lot, but you taste great," he confessed, trying to soften the blow.

"You know, you really should have learned your lesson about lying to me," Caitlyn said softly. "But you're just trying to be nice, so I'll forgive you."

Reaching over to her phone, she tapped the minus sign repeatedly until the screen read 0.0. The sudden wave of relief made Connor's shoulders drop.

"We can finish up our food and go our separate ways, I guess," she said downcast, just as the waitress arrived with their trays.

"Burger for the gentleman, and the chicken Caesar salad for the lady," the waitress said, placing the plates down. She immediately noticed the 0.0 on the screen. "Looks like he's back to being a perfect gentleman."

"Yeah, I guess. Thank you," Caitlyn murmured.

"Thank you," Connor added, his voice much clearer now that the pain was fading.

"Enjoy!" The waitress left, looking a bit confused by the sudden change in atmosphere.

After taking a few bites of his burger, Connor looked across the table. He didn't want the date to end like this. Caitlyn was gorgeous, had an amazing body, and clearly had a fun, dominant streak. He wanted to fix it.

"You know... maybe I just need someone to teach me how to properly enjoy it," he suggested smoothly.

Caitlyn poked at her salad. "I don't know, Connor. It's pretty important to me that the guy I'm with actually craves how I taste."

"I hear it's an acquired taste. Maybe I just need more practice, and I think you'd be the perfect person to teach me," Connor pushed, willing to do whatever it took to get past this dinner.

Caitlyn’s demeanor shifted, a spark returning to her eyes. "Finish your food, and let me think about it," she said, eating her salad with renewed enthusiasm.

Once both of their plates were cleared, Caitlyn checked her phone and spoke up. "Okay, we have ten minutes left on the date clock. First, let's get another round of drinks. Then, I am going to press the small plus button five times every single minute. If you can last until the timer runs out, it'll prove to me that you're truly dedicated to pleasing me. We can extend the date and go back to my place if you can last that long without complaining. Deal?"

Connor hesitated, his stomach turning at the thought of what his groin was about to endure, but the reward was too high to pass up. "Deal."

Caitlyn tapped the large plus sign once, bringing him immediately back to a 1.0. "Okay, so what would you like to talk about until our time is up?"

"I guess we can talk about the subject at hand," Connor replied, keeping his focus entirely on her. "Your pleasure, and my education."

"Your education, and let's not forget your pain," Caitlyn corrected.

The first minute ticked over. She tapped the small plus sign five times. The screen shifted to 1.5.

"Yeah, we can't forget about that, can we?" Connor muttered, secretly hoping she would lose track of the time.

"We sure can't. Your pain is where the lesson begins," she explained. "You can't just dive in between a woman's legs and start licking. You need to get me turned on first."

"And what's the best way to do that?" Connor asked, trying to distract himself.

"There are a few ways, but my absolute favorite is seeing a guy take crippling groin pain just for me," she said.

Another minute passed. Tap, tap, tap, tap, tap. The meter hit 2.0.

"Well, just to let you know, it feels like a heavy, throbbing ache right now. Nothing I can't handle, but I'm really not looking forward to going back to a three," Connor admitted.

"But you'll do it for me, and that is so hot." Caitlyn slipped her hand beneath the table, her breathing hitching slightly. "Next, once you've got me completely hot and bothered—like I am right now—you need to tease me. Tell me how much you can't wait to taste me, how good I smell, all while you kiss my inner thighs and around my vulva."

Another minute rolled by. Caitlyn tapped the screen five times, bringing the level to 2.5.

The sudden jump made Connor let out a low groan, but he forced himself to speak. "And... after the teasing? What's the next move?"

By now, Caitlyn was barely hiding the rhythmic movement of her hand. "After teasing comes the best part. Tasting me. You need to explore every single part of my vulva. Start by kissing my outer lips, then move to licking right between the folds. Make sure you look up and tell me how good I taste every time you take a breath. Then, drag your tongue all the way up from the space just above my asshole, licking deep inside my vagina as far as your tongue can reach. Keep working your way up until you hit my clit."

Before the minute even fully expired, Caitlyn’s excitement took over. She tapped the small plus sign five times in rapid succession. The meter struck 3.0.

"Okay... anything else?" Connor gasped out, gripping the edge of the table to keep his composure.

"Next, you have to read my signals. I might want you to stay right on my clit, or I might want you to start all over again." Snapping back to reality, she realized how public they were and reluctantly pulled her wet hand out from her pants. "Here, lick my fingers clean before we get caught," she commanded, pressing her slick fingertips against his lips.

Connor opened his mouth, sucking her fingers clean. "You taste great," he whispered, this time entirely sincere as the adrenaline fueled his arousal. "Can I have some more?"

"Look at you, you're learning," Caitlyn praised him. She glanced down at the countdown. Another minute had passed. Tap, tap, tap, tap, tap. 3.5. "Just five more minutes, and you can taste it straight from the source."

"Do you two need anything else?" the waitress interrupted, stepping up to the booth. "Maybe some dessert?" She couldn't help but notice Connor's pale, tight expression and the glaring 3.5 on the phone.

"I'll take a chocolate cake to go, if you have it," Caitlyn replied smoothly. "And Connor will take the check, right?" She locked eyes with him, visibly thrilled by the sheer amount of discipline he was showing for her.

"Right... I'll take the check, please," Connor managed to squeeze out.

"No dessert for you, sir?" the waitress asked, confirming.

"If he lasts another four minutes, his dessert is waiting back at my place," Caitlyn answered for him.

Right on cue, she hit the button five more times. The meter climbed to a brutal 4.0. A bead of sweat broke out on Connor's forehead.

"Excellent. I'll get that cake and the bill right out to you," the waitress said. She flashed Caitlyn an impressed smile, silently resolving to up the stakes with her own boyfriend later. "Looks like you two are hitting it off great."

"Oh, look at you, you're starting to sweat! Are you feeling alright?" Caitlyn teased flirtatiously.

"Yeah... doing... great... thanks for... asking," Connor lied, trying desperately to pretend his testicles weren't caught in a vice grip.

"You know, MATS goes all the way up to a ten, and you're only on a four right now. Can you imagine how that would feel?" she asked, mocking him playfully.

"I... really... can't..."

"Oh, look at the time," Caitlyn interrupted. Another minute was gone. She held his pleading gaze as her finger tapped the screen five times. 4.5. "Just three minutes left. You're doing so well."

Connor was actively rethinking his life choices. Why did I get this implant? Why did I agree to this date? Am I really taking this level of pain just to perform oral sex on a girl I just met—something I don't even like doing? Then he looked across at Caitlyn, flushed, beautiful, and completely thrilled by him. It had been a long time since he'd been laid, and she was entirely worth it. Three minutes. He could survive three minutes.

"You're awfully quiet over there. Maybe you should ask for some water when she gets back?" Caitlyn suggested with feigned concern.

"...Yeah..." was all he could manage.

"Here is your cake, and here is the check. Can I get you anything else?" the waitress asked, returning to the table.

"Connor, anything you'd like to say?" Caitlyn asked. "He's having a little trouble speaking right now, so please forgive his lack of manners."

"Water... please," Connor wheezed.

"Of course, I'll be right back."

The waitress hurried to the side station and returned with a tall glass of ice water, completely invested in the drama. "Here you go." She couldn't resist asking, "So, a four point five... what exactly did he do wrong?"

Before answering, Caitlyn watched the clock hit the next milestone and tapped the screen five times. 5.0.

"He didn't do anything wrong," Caitlyn explained to the waitress. "He's just proving to me that he can handle the heat without complaining. He just has to last two more minutes at a five."

"Wow, that's intense. My boyfriend couldn't last more than a few seconds on a five before he started crying," the waitress noted. "What kind of limit did you guys set on the app?"

"We just went with the standard contract. I only have access to a five for an hour. Once his time runs out, we have to negotiate a brand-new deal if he wants to come home with me," Caitlyn said.

"New... deal?" Connor managed to ask, his voice strained to a near-whisper as the crushing force of the 5.0 peak hit him fully.

"Yeah, we'll need a new agreement. I can't have you taking advantage of me once we get through my front door," Caitlyn teased. "Don't worry, I'm really starting to like you. You, and your balls."

"Well, the check is right there whenever he's able to sign it. Have a great night, you two. Sounds like you're going to have a wonderful time," the waitress said, finally leaving them to it.

"Connor, let's pay the bill so we can set up the new deal the second this one expires," Caitlyn said.

Connor reached for the check, his brain completely fried as he tried to calculate a 20% tip through the haze of pain.

"Just leave her twenty dollars, she was a great waitress," Caitlyn guided him gently. Connor nodded rapidly, utterly incapable of arguing. He scribbled a twenty-dollar tip on the line and signed his name.

Suddenly, a soft chime rang out from Caitlyn’s phone.

"Looks like time is up! You did it, congratulations!" Caitlyn announced.

Almost instantly, the excruciating pressure in Connor's groin began to recede, leaving behind a warm, heavy relief. Caitlyn slid her phone into her purse and slid out of the booth, looking down at him with a wicked smile.

"Let's go make a new deal and get back to my place."
