Chapter Two: The New Deal

"So, I am going to draft up a new deal on the app real quick," Caitlyn said, her fingers flying across her phone screen. "Once it's complete and you sign off on it, the app will send you my address. I can't wait to cum on your tongue. I just hope you can deliver with such little experience."

"Yeah, I can't wait to make you cum, and then fuck you afterward," Connor blurted out.

Caitlyn’s expression immediately shifted to one of stern concern. "Let's not get ahead of ourselves, Connor. This is our first date, and traditionally, a first date on MATS is entirely about the woman's satisfaction," she said bluntly. "Let's see how good of a job you do with your tongue first, and then we can talk about exploring other fun activities in the bedroom."

Connor was stunned. Had he really just spent the last ten minutes enduring intense testicular pain just for the privilege of performing oral sex on her? "Is that really the norm in MATS dating?" Connor inquired, trying to hide his dismay. "I just went through a lot, and with a new deal, I'm sure I'm going to go through even more. I would really appreciate it if I could get off tonight, too."

"We'll see. I just sent over the new contract. Confirm it so we can get out of here," Caitlyn said, a sweet, disarming smile returning to her face.

Connor looked down at his phone to review the terms, and a tight knot formed in his stomach. "It says here you'll have access to my MATS until morning, and you want the pain ceiling raised to a six?" He looked up at her, deeply worried. "Don't you think five was painful enough for me?"

"With how well you handled level five, I would normally ask for a pain level of seven, but I like you and I want to make this deal work," Caitlyn explained reasonably. "And of course it has to be overnight, since you'll be staying at my place. I need to make sure you stay the good guy you've been all evening."

"What is this 'expansion mods' condition?" Connor pressed, highlighting a line on his screen.

"Oh, that just allows me to sync some of my favorite custom plug-ins with your MATS unit. It's no big deal, trust me," Caitlyn assured him smoothly. "With the mods active, if you keep doing a great job, I can promise you the best orgasm you've ever had in your life. Click 'Confirm' so we can get moving. I'll even give you a little teaser with my mouth on the way to my place."

That was the selling point. Against his better judgment, Connor tapped the Confirm button. "Let's get out of here," he said as the GPS directions to Caitlyn’s house populated on his dashboard.

"Great!" Caitlyn clapped her hands together excitedly. "It's less than a few miles away, but you have to drive. I took an Uber here. On the way, I can show you some of my own oral skills, but don't you dare cum. Remember the rules of a first MATS date: the lady cums first."

Once they were settled inside his car, Caitlyn immediately leaned over and began fumbling with his belt. "Let's get those balls and dick out. We can use one of my app mods for some extra fun on the drive."

The word fun coming from a MATS user always made Connor nervous, given that the app's sole purpose was to generate pain. "Umm, I'm not entirely sure we need to do that while I'm driving, do we?"

Caitlyn ignored him, fiddled with her phone for a moment, and then turned the screen toward him. Instead of a single primary number, the interface now displayed two separate digital readouts. Fortunately for Connor, they were both sitting at 0.0.

"I can turn the app into a real-time ball pain reader, see?" Caitlyn demonstrated. She reached into his unzipped pants, grabbed Connor's left testicle, and gave it a sudden, hard squeeze.

As she did, the left number on the app instantly spiked to a 4.2.

"Isn't that neat?" she giggled, releasing her grip. The pain reader immediately dropped, but it didn't return to zero—it lingered at 1.2.

"Oh wow, Caitlyn, that really hurt," Connor groaned, keeping one hand steady on the steering wheel.

"Yeah, it should have. It hurts about the same as turning the app to a manual 4.2. But when I hurt your balls with my actual hands, a lingering ache stays behind—hence the 1.2 afterward." As she spoke, the left testicle reader slowly ticked down to a 0.8. "It'll keep dropping until you're fully recovered. Maybe this will help speed it up."

She leaned down and wrapped her warm mouth around his cock.

"Oh god... that feels incredible," Connor gasped, his hips twitching involuntarily. "But I'm going to cum if you keep doing that."

Caitlyn pulled her mouth off him for a brief second to glare up at him playfully. "You better not. Remember: girls cum first. If you cum early, I am going to set the app to a flat seven and leave it there all night to punish you."

It was a bluff; she knew the app had built-in safety parameters that wouldn't allow a dangerous duration of high-level pain, but she also knew Connor didn't know the exact legal regulations of the commercial software. She dipped her head back down, resuming the intense suction.

"Please stop then! I won't last much longer if you keep going!" Connor pleaded, half-hoping she would ignore him and let him blow his load, but terrified of the threat of an overnight level seven.

"Fine. Let's see if I can match righty with the same energy I gave lefty," Caitlyn murmured. Reaching down, she gripped Connor’s right testicle and deliberately squeezed it even harder than the first one, driving the right-side readout to a 5.2 and holding it there for several grueling seconds.

"Please let go! I don't want to crash the car!" he yelled.

She obliged, releasing her grip and letting the number drop to a throbbing 1.8.

"Okay, we're almost to my house anyway. Put these things away," Caitlyn said. To finish the drive, she gave his scrotum a sharp, sudden slap that sent both digital meters spiking above 4.0 for a split second. Connor gasped, fumbling frantically to tuck his sensitive genitals back into his pants while scanning the dark street for her address.

"You can park right in front of my door," she said, pointing toward a townhouse up ahead.

The moment they walked through her front door, Caitlyn wasted no time pulling Connor's pants completely down to his ankles. "Remember, I need to see some real ball pain first," she whispered, cupping a testicle in each of her hands. She looked into Connor’s fearful eyes. "Ready?"

Knowing he didn't really have a choice if he wanted the date to progress, he swallowed hard. "Ready."

Caitlyn didn't hold back. She dug her thumbs deep into the base of each testicle, applying steady, crushing pressure until she suddenly remembered her phone was still buried in her purse.

"Wait, I need to see my numbers!" she cried out, abruptly letting go of him to rummage through her bag.

When she brought the app up, she saw that the resting numbers were sitting at 2.1 on the left and 1.9 on the right. "Oh wow, I must have really done a number on you for the residual ache to stay that high after letting go," she remarked. She set the phone on the floor, screen-side up right between his feet, then reapplied her grip on his bare scrotum. "Ready for round two?"

He was definitely not ready for round two. She had squeezed so hard the first time he was genuinely afraid his anatomy was going to burst. "Sure... but can you be a bit gentler this time? I could really feel your thumbs digging into the tissue on that last one."

"That was on purpose, silly! It's the absolute best way to get the pain numbers up," she replied cheerfully. She dug her thumbs right back into the identical spots. This time, the screen read a clear 6.1 on the left and 5.5 on the right. "Let's see if I can get this right nut up to a 6.1 to match." She shifted her weight, applying extra pressure to his right side.

"Ahhh! Please stop, please let go! You're going to break them!" Connor yelled as the right-side meter spiked to a brutal 6.5.

"Shhh, you're going to alert my neighbors," she whispered, slowly easing up on the manual pressure. "Okay, I think that's enough for a baseline. I am so incredibly horny. I can't wait to feel your tongue inside me."

Caitlyn snatched her phone off the floor, grabbed Connor by his erect penis like a handle, and led him directly into her bedroom.

"You remember the instructions I gave you at the restaurant, right?" Caitlyn asked, stripping off her clothes and lying back on the bed.

"Yeah, I think so. A bit of teasing first, right?" he replied, trying to refocus as he crawled onto the mattress and began pressing warm kisses along the soft skin of her inner thighs.

"Oh, and I forgot to mention: once you start working on my clit, do not stop until I explicitly tell you to," Caitlyn instructed, her voice already growing breathy. "I can cum multiple times in a row, so you need to keep licking right through my orgasms."

"Yes, ma'am," Connor agreed.

Getting a close-up look at her vulva, he noticed she had a thick, natural mound of pubic hair above her clit and a lighter trimming surrounding her opening. Normally, Connor wouldn't be particularly enthusiastic about performing oral sex, let alone on an unshaved woman, but after everything his body had been through tonight, he found himself intensely aroused by the sight and scent of her. His mouth watered.

"I can't wait to taste you," he told her honestly.

Lying on her back, Caitlyn tapped her phone screen again. "Keep teasing me," she murmured. "I just activated an automatic timer mod on your MATS. It's going to add a tenth of a point to a random testicle at completely random intervals. Once you make me cum, the app will lower the numbers back down. Just keep me orgasming, and your balls will be fine." She let out a wicked little giggle.

Connor barely even processed the threat; he was too consumed by the urge to finally taste her. "Can I taste you now, please?"

"Yes. I'm so wet. Clean me up with your tongue right now."

Connor didn't hesitate. He parted her outer labia and began lapping upward. "Mmm..." Caitlyn moaned, gripping the sheets as Connor thoroughly enjoyed her flavor. Remembering her instructions, he moved his mouth lower, kissing the sensitive skin just above her anus before plunging his tongue into her vaginal opening as deep as it would go.

"Ahhhhh!" Caitlyn gasped, arching her back as his tongue stroked all the way up her wet slit.

Connor caught a quick glimpse of the phone screen on the mattress: his pain numbers were currently hovering at 2.1 and 2.6, registering as a mounting, heavy ache.

"Wait for my signal before you move to my clit. Keep cleaning my pussy," she ordered. She wanted to wait for the background pain to become more severe. "I want your balls to really hurt right when you make me cum," she confessed, keeping her secret goal to herself—she wanted both meters above a 3.0 before her first release.

Connor kept working, his groin tightening uncomfortably as the background mod ticked the numbers up to 2.2 and 3.1.

"You're almost there... keep going..." Caitlyn couldn't wait any longer. She reached over and manually boosted both testicle pain levels by a full point.

The sudden, sharp escalation to 3.2 and 4.1 made Connor flinch, pulling his tongue away to protest. But Caitlyn immediately pressed her hand against the back of his head, forcing his face back down. "Make me cum! Lick my clit until I cum!"

Connor pushed through the deep, crushing ache in his lap. He began circling her clit with his tongue, ignoring the soft pubic hair pressing against his nose.

"That feels so good... keep doing that!" Caitlyn cried out, no longer caring about the neighbors.

Connor kept up the steady rhythm, but he didn't realize he needed a more aggressive technique to push her over the edge. The random escalation mod continued to climb, favoring his right side and bringing the numbers to 3.2 and 4.5. The throbbing was becoming a major distraction, but knowing that an orgasm was his only ticket to relief, he kept focusing on her clit.

"Harder!" Caitlyn commanded, her hips twisting. "Side to side and harder! Make me cum!"

Connor obeyed instantly, applying firmer pressure and flicking his tongue side-to-side across the swollen knot of nerves. The meters reached 3.7 and 4.6.

"FUUUUUCCCKKKK!" Caitlyn screamed, bucking violently against the mattress. Connor held on, struggling to maintain contact with her shifting hips, intensely grateful when he felt the sudden electronic relief wash over his groin. Unfortunately, the app only dropped the settings a few points, leaving him resting at a tense 3.5 and 4.0.

"Keep going," Caitlyn panted, barely letting her first orgasm fade. "Put a finger inside me. Make me cum again."

Connor complied, though he noted with some dread that his baseline pain was still remarkably high. He slid his middle finger inside her slick channel, finding it a bit awkward to maintain a steady finger rhythm while keeping his mouth firmly locked on her clit. He pushed through the fatigue, hoping a second climax would clear the meter completely.

"Yeah, just like that... move your finger in and out," Caitlyn moaned. The numbers began to creep right back up: 3.8 and 4.2. "Yeah! Yeah! Keep going, make me cum again!" she shrieked, bucking with even greater intensity than before. It was a massive, full-body orgasm, providing Connor with a welcome reprieve as the readouts dropped to a manageable 3.0 and 3.2.

"Keep your mouth over my clit, but stop licking for a second. I need to recover," Caitlyn whispered, her chest heaving. "Your pain levels are a little too low anyway. I want them to go back up before you make me cum a third time. Play with my nipples while we wait for your numbers to rise."

Connor did as he was told, rolling her nipples between his fingers. But he secretly figured that if he started stimulating her clit ahead of time, he might be able to trigger an orgasm before the background mod could climb too high. He lowered his head and began circling her clit with his tongue again.

"Hey, you're supposed to wait," Caitlyn complained, though she didn't actually pull away. "You need to be punished for cheating."

She grabbed her phone and manually pushed both pain channels to a flat 5.0.

The sudden, overwhelming spike in his testicles made Connor freeze, his vision blurring for a second. Realizing his absolute best option was to speed things up, he doubled down. He inserted two fingers into her vagina, working them rapidly while his left hand massaged her breast and his tongue aggressively worked her clit.

This time, it was taking much longer to bring her to the edge, creating two serious crises for Connor. First, his tongue was becoming incredibly exhausted and cramping up; he was genuinely terrified he wouldn't be able to finish the job. Second, even though he knew the MATS tech caused zero physical tissue damage, it felt entirely like his testicles were about to pop under immense pressure. Unbeknownst to him, the background scaling had driven his metrics to a staggering 6.1 and 6.6.

He powered through the agony, pouring every ounce of his remaining energy into his mouth and fingers.

"OH FUCK!!!" Caitlyn shrieked, wrapping her arms around his neck and pinning his face tightly against her vulva. "I'm cumming!"

She bucked wildly, locking him in place so he didn't even have to worry about keeping up with her movements. This final, shattering climax forced the app to grant a major reduction, though the meters still left him with a lingering, heavy throb at 4.2 and 4.5.

Connor collapsed slightly, pressing a soft kiss to her wet skin. "I think... my tongue needs a break," he wheezed, his jaw aching.

"You've only been eating me out for thirty-five minutes," Caitlyn complained playfully. "You need to get that tongue in better shape if you want to keep up with me. Fortunately, I know an excellent way to give that tongue a workout in the future." She checked her app, noting the 4.3 and 4.5 readouts. "I mean, you can take a break all you want, but these numbers are just going to keep climbing."

"Caitlyn, please, can you just turn it down?" Connor begged. "I am really starting to love eating your pussy, but my tongue literally cannot keep up with your demand right now."

Caitlyn looked down at him, then glanced at his rigid crotch, admiring his build. "I guess I can't expect a guy who doesn't normally perform oral to get me off more than three times in a row on his first try," she conceded. "Tell you what: go put my chocolate cake in the fridge and grab me something to drink. Cumming like that always makes me incredibly thirsty. When you get back, we can discuss some relief for your balls."

Connor practically scrambled out of bed, returning a moment later with two cold bottles of water. "So, can we talk about turning the MATS off now?" he pleaded, handing her a bottle as his groin throbbed at a 4.4 and 4.6.

"You knew what the terms were. You have to keep giving me orgasms until I say we're done," she teased, taking a sip. "You'd just take advantage of me if I let you break the contract whenever things got tough. But... since it's your first time going that long, I'll give you a break. I'll set the digital numbers to zero, but under one condition: I get to play with your balls manually until your tongue is rested enough to finish the job. Deal?"

Recognizing it wasn't a stellar bargain, but willing to do anything to get the electronic signal turned off before he was entirely immobilized, Connor nodded. "Deal. What do you want to do while my tongue rests?" He harbored a secret hope that some sexual reciprocity for himself might finally be on the table.

"Let's just watch some TV while I play with your balls. Come lie next to me," she instructed.

Connor climbed back onto the bed, hoping that a little physical contact might inspire her to use her mouth on him again. He was not that lucky, and he really should have known better.

The moment his head hit the mattress, Caitlyn reached down, wrapped her fingers around his right testicle, and pinched it hard.

"Aaaahhhhhh!" Connor yelled, completely caught off guard by the immediate, sharp pain. "You know you don't have to try to pop it every time you touch me, right?" he gasped, forcing a strained, flirtatious smile.

"Don't worry, I won't damage you. I just really like squeezing these things," she said. She pinched down even harder, causing the smooth skin of his testicle to pop out from between her fingers. Connor jumped at the sharp, biting sensation.

"What do you want to watch?" she asked casually. Her left hand reached for the TV remote on the nightstand while her right hand immediately re-clasped his right testicle.

"It's your house, we can watch whatever you want," Connor said, completely unable to focus on the television as her fingers maintained a steady, heavy pressure on his right side.

"Well, how much time does your tongue need before we get back to work?" she asked. She applied another burst of sudden pressure, making the testicle slip through her fingers a second time and causing Connor to twitch against the sheets. "We could watch a thirty-minute sitcom, or a two-hour movie," she continued, her fingers settling right back into a firm grip.

Connor was far less concerned about his tongue and entirely focused on surviving her hands. "I think a half hour is plenty of time for a full recovery."

"Sounds good," she said, turning on the TV. She wrapped her entire hand around his right testicle and gave it a sustained, heavy squeeze. "Let's finish whatever show this is, and then see if we can get that tongue back to work." Connor could only grimace in silence.

After fifteen minutes of trying to ignore the fact that his right side was being treated like a flesh stress ball, he broke. "Hey... do you think you could give my right nut a break for a second? You've really been working it over."

"Let me have my fun. You're the one who broke our deal—I should be having my pussy licked to my fifth or sixth orgasm by now," she countered, giving him one more sharp squeeze. "But I guess I can move to the other side if you're going to be such a baby about it."

She released his right side, granting him a brief wave of relief, before immediately clamping her fingers around his left testicle. "This show isn't really keeping my interest anyway. How is your tongue feeling?"

"I think I can get back to work if you're ready," Connor replied eagerly, desperate to get her hands away from his groin.

"Great! Just give me a few minutes to even out your ball pain first. I like to see both sides hurt the exact same amount—it's only fair," she said. She took his left testicle fully in her palm and squeezed with nearly everything she had.

"Ahhhhh! Please, please, please!" Connor squeezed his eyes shut. "You're going to break it, please let go!"

"I told you not to worry, I'm not going to damage you," Caitlyn assured him smoothly. She released her grip, leaving his left side throbbing fiercely to match his right. "I just wanted to balance the scales before round two. Now, get rid of that pillow you're on."

She threw her left leg completely over his torso, mounting him in one fluid motion. "I want to sit on your face."

She inched her way up his chest, snatching the pillow from beneath his head and tossing it off the bed. "I can't go any further up the headboard, you need to scoot down some, silly," she told him.

Connor was simply happy his testicles weren't currently being crushed, so he readily complied, sliding down the mattress. As Caitlyn lowered her wet vulva directly over his nose and mouth, a strange thought crossed his mind: Maybe there's a psychological trick to this implant, because enjoying the smell and taste of a woman is so much sweeter when your balls are aching.

The moment her skin pressed against his lips, he didn't even wait for a command; he began lapping her clean.

"Fuck yeah... you're really starting to crave my pussy, huh?"

Connor couldn't reply, offering only a muffled grunt of agreement against her wet skin. He was entirely focused on seeing how deep his tongue could explore.

"You can start working my clit again as soon as you've had your fill of my juices," Caitlyn murmured, her hands reaching backward between her thighs to grip his scrotum once more. Connor flinched at the initial contact, but he kept his rhythm steady, starting slow just like she had instructed.

Over the next thirty minutes, he brought Caitlyn to three more shattering orgasms while her hands playfully kneaded, squeezed, and rolled his testicles off and on. Finally, completely satisfied, Caitlyn slid off his face and stood up.

"I am so glad you decided to get the MATS surgery and join the app. This has been a really fun night," she said, walking over to her dresser and pulling out a pair of boy-short panties. "I hope you had fun, too," she added, stepping into the underwear.

Connor sat up, looking at her with a mix of exhaustion and absolute desperation. His penis was still completely rigid. "You're getting dressed?"

"Yeah. Well, I'm putting panties back on, at least. My pussy is officially done for the night," she said, sitting back down on the edge of the bed. "I hope you didn't think we were going to have sex?"

"Were we not just having sex for the last hour and a half?" Connor asked, utterly perplexed.

"No, that was just you eating my pussy. That wasn't sex," she teased, her eyes glinting. "I explicitly told you at the restaurant that I don't have sex with a guy on a first date. I never said anything about not letting you eat me out, though." Fully aware that his testicles must feel like overinflated balloons after being teased and handled all night, she leaned closer. "Why? Did you want to do something else?"

"Well... I was really hoping I could get off at least once. I think that's only fair since I just gave you six orgasms," he confessed, his voice heavy with disappointment and intense frustration.

"Oh, you think that's only fair, huh?" Caitlyn teased. She slowly crawled down the mattress, positioning herself between his spread legs. "Okay. Would you like me to use my hand, or my mouth?"

Connor would have accepted a stiff breeze at this point, but remembering how incredible her mouth had felt in the car, he took a gamble. "I think it'd be fair to get a blowjob after all the work I put in today, right?"

"Yeah, I think that's fair," she agreed softly. She leaned down, pressing a warm kiss to the head of his shaft before sliding the entire length into her mouth.

Connor's head hit the mattress, his eyes rolling back. He had never felt an ejaculation so backed up in his entire life; his whole body felt like a ticking time bomb.

Caitlyn engulfed him completely for a long, intense stroke, then pulled back just enough to look up his torso. "But don't you dare cum in my mouth. I am going to be really pissed if you shoot your load down my throat." She gave him a terrifyingly serious look, doing her best to hide the fact that she secretly wanted him to orgasm in her mouth. "If you cum in my mouth, I am going to open the app, crank the MATS up to max pain, and leave it there for the rest of the night."

She immediately went right back to sucking him.

The threat terrified Connor to his core. He was already right on the precipice, she was incredibly skilled, and his body was completely primed to blow. He desperately wanted to empty his balls, but the mental image of an automated level seven pain setting lasting until sunrise was enough to break his focus.

"In... that... case... I think... a handjob... will work!" he gasped out, trying to push her shoulders away.

"Noope," Caitlyn mumbled around his shaft, not even bothering to release him. "Doon't cuuumm," she teased, intentionally swirling her tongue to drive him over the edge. She knew there was absolutely no stopping it now.

Connor tried every mental trick in the book. He even tried to physically slide backward up the bed to pull himself out of her mouth, but the moment he moved, Caitlyn’s hand reached down and firmly anchored him by his sensitive scrotum, pulling his hips right back down.

Less than three minutes into the overwhelming pleasure, Connor cried out, "PLEASE! I can't hold it back anymore!"

Caitlyn didn't stop; she accelerated the pace, her throat tightening around him until he completely lost control, pumping load after thick load after load directly into her mouth and down her throat.

Caitlyn tried to swallow the mouthful of cum that didn't shoot straight down her throat, but the sheer volume was too much, leaking slightly from the corners of her lips. She used a finger to scoop the stray semen back into her mouth with a slurp and a grin. "I thought I told you not to cum in my mouth?" she joked, leaning down to lick the remaining tracks from his shaft and thighs.

"I'm sorry... I couldn't help it," Connor panted, his heart hammering against his ribs as a deep, euphoric relaxation finally washed over his entire body. "I told you I was going to blow, but you didn't stop!"

"Too bad, I told you not to cum in my mouth," she replied, still licking her lips. "You need to be punished for that."

"You're right, I am sorry," Connor said defeated. "Think you can at least go a bit easy on me, since I really tried to not cum in your mouth?"

"Don't worry, babe. I actually love getting a mouthful of cum right after a good ball beating," she reassured him, slurping and scooping up every drop of cum that wasn't already down her throat, before giving Connor's balls a light kiss.

She crawled up his body, collapsing happily onto the pillow next to him. She pressed a warm, lingering kiss to his lips before gently cupping her hand comfortably over his completely relaxed and empty balls.

"I'm so glad we met tonight. Let's go to sleep."
