Summary:

Karamatsu gets a job. It's a bit more involved than he expected. The rest of his brothers decide to work too.
[Now with Cow Totty]

Notes:

First 2.3k is backstory/set up/karamatsu getting manipulated… for some reason i always gotta put backstory. If you want to skip that, you can. It leads into Nipple Clamps/Injections before pure cow related sin.

There's no specific page break for it, but i can add one in if wanted.

I don't really know what pairing tag would be used in this context, but strangers do things to kara. So Karamatsu/Mob ?

Chapter Text

It had been more than a week since Karamatsu had returned home, leaving Chibita’s house and his wayward attempts at finding a job behind. And yet. He hadn’t wanted to leave his resume behind, after all the work and all the effort and help that had been put into it. He hadn’t managed to find a job… But maybe that had just been a bad week? Perhaps, if he tried another time, he would be much more successful.

It wasn’t like it was awkward around the house, no- Karamatsu did his best to fill in the quiet times, when Todomatsu touched his eye and looked at Osomatsu in that way, perhaps not trying to manipulate his brother (Karamatsu always thought the best of him) but maybe just trying to tell Osomatsu that not all could be forgotten so quickly. He was forgiven, of course, they were brothers and what were brothers if not best friends? But Osomatsu seemed to assume forgiven and forgotten were equals.

Karamatsu stepped in these times, because he was the second eldest, and he loved his brothers, so of course it was his responsibility to share that love with them, and he knew the best way was with a gentle word. Or a few. An entire poem, read to the two of them left Karamatsu on the ground courtesy of a gentle tap from Ichimatsu. But it had ended the confrontation, and that meant Karamatsu could pose heroically upon the ground as he recovered. Poor Ichimatsu must have thought it was some sort of twitch, because his brother took it upon himself to straighten out Karamatsu’s body through love-taps with his foot. All pain was fleeting in the face of happiness.

His thoughts would come around to getting a job, once he was left alone. Sometimes even when he was with his brothers, he would speak of it, and no one protested, which Karamatsu took as a sign of approval. It had to be. And so in his spare time, tucked between the well worn pages of his magazine, he checked and double checked and even edited his resume.

Only to be rejected once again.

Karamatsu swallowed his disappointment, shaking his head, and smirking at the despondent face of one of the employment agency’s workers. It was reasonable, he assumed, that there were no jobs suiting his high level of qualifications. Clearly he’d just have to come earlier in the day!

The next day, he suffered the same fate, as did the day after. It took a bit longer for him to recover, on the third day. Maybe he should just go back to his brothers for now. They must miss him, for he had spent hours waiting, and speaking, and trying. And yet, Karamatsu couldn’t keep the hopeless look off his face. He sat across from the agency in a bench, sighing and fixing his hair, a repetitive motion that helped him stay focused as his thoughts ran away from him. He was considering writing a song about his current emotional state when he was interrupted.

Perhaps, this was his lucky chance? Some lovely lady was here to brighten his day with offers of companionship and opportunity? Fate’s mistress, come to take his own hand and lead him off on untold riches- Karamatsu turned to the stranger, pushing up his glasses, “Ah, bonjour, my good l- lad.” He was not facing a lady. A somewhat harried man, perhaps in his late thirties, but Karamatsu could tell he still possessed youthful virtues by the nice set to his eyes. No lady, but Karamatsu had lived with disappointments, and this one barely warranted a second thought. “How may I be of assistance to you?”

The man gave him a slight smile, rubbing his hands together. “Ah, yes… Well. You could be of assistance to me- You see, my companies new, and this agency will only register companies once they’ve gotten all their credentials filed, and we won’t have those back for another few weeks… But we really need to hire some new people, and soon, so I’ve been scouting this area for a while…”

Karamatsu’s brain caught onto one part of the man’s monologue, and stuck to it. ‘Need to hire some new people’. Present tense. As in it was still happening. And this man had approached him, who had been so desperate- truly, fate had seen his need! Lady fortune may not be here in person, but a messenger had gotten to him and Karamatsu knew that this was his chance. He hadn’t found a job before, not in these days of hunting, nor in the days he’d been staying with Chibita. He needed this. He didn’t want to return to his brothers empty handed- not that he’d even mentioned this to them, but Karamatsu felt like they knew anyway. And if he showed his worth well, he could prove that he was better than pears!

Apparently he’d said that last part aloud, because the man was looking at him with a slightly awkward expression on his face. “...Yes, we wouldn’t hire pears. But, you would be interested in this job, yes?” He wrung his hands again, but Karamatsu was willing to ignore any awkward pauses in speech of body habits because this was his chance.

“Of course!” Karamatsu responded, so eagerly that he knew he had to restrain his passion. He posed, taking off his glasses. “I am glad to have impressed you! Do you need my resume? Anything at all? Oh, is this the interview process. Excusez-moi, for I am not dressed properly!” He was only wearing his second best pair of jeans. Where were his jorts when you needed them?

“Oh… no, no, it is fine.” The man smiled awkwardly, extending a hand. “You can call me… Mr. Sato. And you are?”

“And I am Karamatsu Matsuno.” He could see nothing odd with the manner of how the man introduced himself. Couldn’t, not when the man was being so generous to offer him a job. Even when he couldn’t help but be curious as to what made him worthy- Karamatsu knew he looked handsome and trustworthy and hardworking at all times, but he could admit the last few days he’d looked more desperate than anything else. He pushed his worries out of his mind, and smiled onwards.

“Mr. Matsuno… Well, would you-”

“Please, please! Call me Karamatsu.”

Sato smiled, awkwardly to Karamatsu’s mind, but he was not one to judge the beauty of another’s smile. Everyone had their differences. He offered his own reassuring grin back.

“...Yes, Karamatsu then. My employer is in desperate need of help- We could do the interview now, if you’re ready? And you have your resume… You won’t need to be anywhere?”

“No, no, of course not. And I am always ready to talk about my talents!”

“Wonderful. I can tell you a bit about the job on the way over… Come with me- it’s not too far, but we can take my car.”

The car was completely nondescript, but Karamatsu was enchanted by the possibilities. More so when the man began to talk about the job itself. He even stopped with the awkward breaks, which was nice. Clearly this part was much more rehearsed. Karamatsu understood that. He also rehearsed some of his longer lines in front of a mirror.

“I work for a nutrition company, one that handles very specialized products. We’re hoping to start up a branch in Japan, but like I said, we had some misfortunate in the beginning. We’ve mainly been exporting to interests in China, but we know there are potential customers in this area as well. We have staff in most areas, but our newest product line is where we need to hire new hands.”

“The chance to help others gain strong and beautiful bodies… I’ll be helping with that?” Karamatsu couldn’t believe it- a job that sounded nearly perfect for him. “What exactly will I need to do?”

“Well, our newest line is focused on health drinks. Completely organic and all dairy based. You’ll be helping out with the production of these- Oh… please don’t look alarmed! It may sound complicated, but we will… train you in all the skills you’ll need.” Sato’s smile was thin and watery. “The only thing you need to do is pass a short examination. Oh, we will be working around some potentially hazardous chemicals, but there’s preventative measures for that.”

Karamatsu wanted to ask more on the ‘preventative measures’- not that he was worried, no, just curious- but the car turned into a moderately sized shopping center and pulled up in front of an innocuous storefront, a ‘Coming Soon’ banner hung in the window. Behind it, he could see neat little aisles and displays filled with all manner of supplies.

He could imagine himself working there- perhaps running the counter, with a dapper uniform and a charming smile for the various patrons. Wait, he’d be working in production- well, maybe after a while and saw how good his work ethic was, they’d let him try other positions. Karamatsu was certain it would happen.

He was led deeper into the store and into the back area, and then past the back area into an odd little office. There were two more men in the room, one with a lab coat and a soft smile, the other drooping tiredly but whose eyes shone with excitement. Both were older- around a similar age to Mr. Sato.

“Dr. Watanabe, Mr. Yoshida.” Sato bowed his head respectfully as he entered. “This is Karamatsu Matsuno. He’s looking for a job, and I felt he would fit well at our company. Oh…Yes. I recommend him for working in production.”

The man in a labcoat- Karamatsu assumed that to be Dr. Watanabe- looked at him with a worried expression. “Production? But that can be so taxing on the body; are you sure he’s strong enough?”

Karamatsu felt almost cheated. He’d gotten so close to a job, and now they weren’t even sure he could do it? He cleared his throat, speaking up. “Ah, I assure you, my potential employers, I am fit and ready to do any task bestowed on me! Anything at all.”

“Hmm… would you be willing to do a quick physical then? We need to check up on your body. And if you pass that- well, you’re almost guaranteed to have the job.”

“Of course!” Karamatsu answered quickly, before they could rethink his ability.

“You’ll also need to sign a waiver.”

He didn’t think twice, skimming over the paperwork before signing his name with a flourish. The papers were taken from him, and he was led into yet another room, this one greatly resembling a doctor’s office. Karamatsu sat on the table in the center.

“Ah, Mr. Matsuno, please remove your clothing and stand up.”

“Heh- how much?”

“All of it.”

For the first time, Karamatsu felt almost uncomfortable. The other two men were still in the room, and the doctor seemed to be appraising him… He reassured himself that was only what the man was supposed to do. And he really wanted this job. Plus, he enjoyed his body, there was no reason to feel ashamed, was there? Squashing the feelings of discomfort, Karamatsu removed his jacket, then shirt, then pants. He hesitated once more, fingertips skirting around the edge of his briefs. What kind of job asked-

“Ah, I’m afraid we’ve had a misunderstanding.” Karamatsu jerked his head up, seeing that the doctor was staring at him, looking awkward. “You’re fine just like that.”

He relaxed again. And the other two men were gone from the room as well now- clearly he’d been worried over nothing. There was no reason to fret. It was just him and the doctor.

The man moved closer, scanning him up and down with his eyes. Karamatsu, feeling a bit more confident now, struck a pose, extending his leg as the doctor looked him over.

“Hmm, can I take a closer look?” The doctor gestured to his his legs.

Karamatsu wasn’t entirely sure what that entailed, but he didn’t want to ask- then they’d think he knew nothing. “Of course! Go ahead.”

The man knelt by him, pressing his fingers to Karamatsu’s calf muscles. He tensed as the doctor continued to touch his legs, rubbing the muscles of his legs before moving upward to prod at his thighs. He resisted the urge to squirm or kick the man off, and held still with what he considered admirable control. The doctor stood then, startling Karamatsu into jerking back. At a sharp look, he still once more as the man inspected his chest, pressing two fingers to each of his pectorals in turn. The seconds seemed to be dragging on agonizingly long, but eventually the man stepped away, grabbed a clipboard and began taking down notes. All without saying anything to Karamatsu.

Karamatsu cleared his throat in an attempt to get the man’s attention. He hated this sense of anxiousness. He cleared his throat once again, much louder, when the doctor continued to ignore him. “Excuse me? Doctor?”

“Hmm? Oh yes, Mr. Matsuno… I’m just recording the results.”

Karamatsu couldn’t decipher the man’s expression. Did he approve of him? “Ah… Will I get the job? Did I pass?” He tried to keep the hope out of his expression, wanting to keep up his cool appearance.

“I’ll need to discuss this with my manager, but if you get the job you will hear back from us within a week.”

He couldn’t keep his expression from cracking. It sounded like an easy way to reject him more than anything else. Karamatsu swallowed, ducking his head as he tried to keep his emotions under control. Would he give up here? He couldn’t- not when he’d gotten so far. “Please-” He begged, voice a harsh whisper, “Please I’ll do anything. I don’t want them to know... “ His brother’s knew nothing about him trying to find a job, but what if they could look at him and see how much of a failure he was?

“Well…” Karamatsu jerked his head up like he’d been yanked. “I think my boss will want you… I can pre-approve your application. Just don’t mess up, it’ll be on me. I think you’ll work out fine, for what it’s worth.”

“Oh, thank you, my good sir! I won’t let your expectations down!”

“I’d hope not. Now, there’s a few more forms you’ll have to sign before we can officially hire you. There are a few liability waivers due to the nature of the work, if you don’t understand something feel free to ask about it. Oh, do you have any allergies? There is a medicine you will have to take to begin work; a simple proactive measure to increase your immunity to some of the rarer substances we will be working with.”

Karmatsu couldn't follow the rest of the man’s words- when the names of the chemicals in the medicine exceeded four syllables, the man gave up on trying altogether. These people were kind enough to hire him- he was sure he could trust them in their nutrition work, after all, that was the purpose of the store. He wasn’t entirely sure his job should be prescribing him medicine but then again- he’d never had a job before. Perhaps this was commonplace in nutrition stores. He decided he could ask Totty when he got home.

When he finally arrived back to the house, no one else was around. It was almost nice, in a way. Karamatsu ignored the sharp longing to tell his brother’s of his achievement. That he’d gotten a job and he hadn’t needed their help- and it would be a good job too. The pay was excellent and he’d be given health benefits and discounts on store merchandise… Karamatsu sighed heavily, brushing his hair back with exaggerated nonchalance. He really did want someone to share his news with. Perhaps his dearest mother? He couldn’t hear her in the house either. Another time then.

Having nothing better to do, he decided to get started on the medicine he’d been given. An innocuous bottle of pills, and he had to take one each day for two weeks after eating. And then he’d be ready to return to the job. And even for just this part, he’d still be getting paid. Taking out leftovers from the refrigerator and quickly heating them up, Karamatsu made himself a little dinner, settling in to eat. He inspected the pill as he chewed. A capsule, white and large sat in his hand. Karamatsu swept his hand upwards, “The things I do for my job!” He’d always wanted to say something like that. After eating, he took the pill, a slightly chalky aftertaste all that remained in his mouth.

When the rest of his brothers arrived home, Karamatsu decided against telling them of his job. He wanted them to ask about why he looked so proud and accomplished. But only Ichimatsu seemed to notice, and even that was questionable.

One week later had Karamatsu struggling to fit into his jeans. With a frown, he wondered if they’d shrunk in the wash. With a final inhale, the man sucked in his breath tightly and pulled as hard as he could, the jeans finally slipping over his thighs. They were so tight. Maybe he did need new ones?

Another few days had Karamatsu catching Todomatsu looking at him. His brothers nearly always averted their eyes, but now- perhaps they’d finally realized the truth of his perfect fashion? Or maybe they knew the culprit behind his shrinking clothes. His tanktop stretched across his chest, but even he was hard pressed to admit it was just the fabrics fault. His pectorals strained the fabric, but Karamatsu didn’t want to admit that he was becoming…. Rather top heavy.

When two weeks had passed and his appointment with his job was in a few hours, Karamatsu resolved himself to ask about the weight gain. Because that’s what it was. His thighs were thicker, giving him the illusion of a curved figure that he’d never had before, and much to his embarrassment (and even his arousal) his chest was fairly ample. Karamatsu could cup his chest now, squeeze and press his fingers into his soft skin. And he was much more sensitive all over. A few masturbation sessions had quickly proven that. He could only conclude that it was some sort of odd side effect of the medicine, and he’d just have to ask about it and it would all be fixed.

As he was led back into the room that so resembled a doctor’s office, Karamatsu cleared his throat to command the two men’s attention. The doctor and his boss turned around, both looking curious. “Ah… Recently I’ve been gaining a bit of weight. Is that a normal side effect of the medicine? I have worn it well, of course, but I would still like to know if it was… expected?”

“Oh yes, it can be- Your chest has broadened up nicely. The augmentation in the hamstrings is a rare chance, but it won’t affect your chances. In fact, it means you’re even more responsive to the chemicals needed to work here, which is great news!”

“It… It is?” Karamatsu didn’t quite know what to make of this. But both men were smiling, pleased with him, approving of him. “It is.” He echoed, much more confidently. “All intentional, of course. I’m ready to start working now!”

“One more examination, and then you’ll need an injection through the papilla. Are you alright with that?”

“Ah…” Dare he ask what the papilla was?

“Great. Let’s get started then! You’ll need to remove your clothes once more.”

Karamatsu nodded, hiding his shame. He hadn’t had a chance to ask. But it couldn’t be worse than what had happened with Hatabou.

“This inspection will be a bit more hands on, but of course, it was all mentioned in the waiver. Please remove your under clothing as well this time.”

He felt himself flush, but he couldn’t complain. He’d skimmed over the waiver, so this was his own fault for not negotiating terms. A real cool guy would never back out on their promises, so he wouldn’t either.

Karamatsu realized that he and the doctor clearly had different ideas of what ‘a bit’ meant when the man laid hands on his thighs. One hand on his inner thigh and the other on the outer side, the doctor was kneading Karamatsu’s muscle like some sort of parody of a massage. “Don’t squirm.” He was directed, but it was so difficult with the new sensitivity of his skin. Karamatsu squeezed his hands together, resolutely ignoring the sensations. And it was so awkward, with the man so near his dick… But even his new found resolve failed when the doctor moved around to his backside, groping his ass. Karamatsu jumped forward, startled, about to protest when the man gave him a look that screamed disappointment. Flushing in humiliation, Karamatsu stood still once more.

With no other choice but to stand there and take it, Karamatsu almost began to enjoy the inspection. The older man’s hands were soft on his body touching and stroking up the curve of his back and across his body, soothing and tingling all at once. Karamatsu was half-hard from just being touched- the shame almost killed his arousal, but fortunately the doctor didn’t comment on it.

Finally the man was back around to the front, and Karamatsu held the hope that this was almost done, but then man touched his chest, squeezing his breasts. “E-excuse me?” He tried to keep his cool, but it was difficult, when his body seemed to want to do exactly opposite.

“You’ve developed very well- there’s only one more step- The injection we mentioned earlier. We’ll need to prepare the area, of course. Please, sit back on the table.”

Dazed and with his protests being swept aside, Karamatsu stepped back, retreating to sit on the table. He ignored his throbbing dick, trying to arrange himself so that his hardness wouldn’t show. What they must think of him…

When the doctor neared him once more, he didn’t directly return Karamatsu. Instead, he placed a small toolbox next to him, opening it up and removing a small package and ripping it open. “Like I said, we’ll be doing this on both papilla. Please do not squirm- unless you think you need to be restrained?”

“N-no sir! I have excellent control over my body!” And yet for all his words, he couldn’t control his reaction when the man took the disinfectant wipe and rubbed it over his nipple. Karamatsu inhaled, shivering at the sudden coldness on that sensitive region. One nipple was wiped with alcohol, hardening with the coolness of the air. Another package was opened, and his next nipple was given much the same treatment.

That was the moment Karamatsu realized exactly what this was leading up to. Somehow he’d pushed it out of the mind, but injections meant needles. He went to grab at his chest when the doctor caught his hand, perhaps foreseeing his reaction. “Don’t worry, it won’t hurt. I thought you said you could handle this?”

Karamatsu hated this, being sneered at like he was nothing- but he grinned weakly and nodded. “Of course I can!”

The man withdrew not a needle, but a pair of clamps. “These won’t stay on long- just to make sure there’s no mistake in the injection process.” As the first nipple clamp was placed on him, Karamatsu wondered what exactly he'd gotten himself into. But it had already started- it was far too late to back out now. The first clamp latched onto his skin, and Karamatsu was unable to stifle the squeak that escaped him. He was able to control his reaction when the doctor put the second clip on him, biting his lip as his nipple was squeezed between the two metal sides.

And finally the needle was pulled out, and Karamatsu found himself torn between looking anywhere but the syringe, or staring right at it. He exhaled, heavy and shuddering, before finally dragging his eyes to the ceiling, already anticipating the sharp sting as the needle entered him.

It was much more than a simple pinch of a regular shot and Karamatsu found himself sharply regretting ever agreeing to this, but it was far too late to back out now. Not when he could feel whatever was injected into him like some sort of heaviness in his chest, spreading through his pectoral and aching. The other shot was done in quick succession, and Karamatsu now felt evenly balanced, pain on both sides.

“You’ll need to wait for ten minutes to make sure you don’t have any side effects, but if all goes well you can start working right away!” Karamatsu only faintly registered the doctor’s words, not even bothering with a farewell as both men exited the room. He was still staring at the ceiling- oh, when had he started lying down? He couldn’t quite track the progression of time, only the fact that whatever he’d been injected with seemed to be burning through him, heat rising in each of his breasts.

Eventually, the heat seemed to settle, dwindling into a latent sort of burn that he could ignore. However, it was replaced with a sense of heaviness. Karamatsu knew something had changed- he just couldn’t figure out what. He carefully reach a hand up to cup his left breast, thumb brushing over a still-clamped nipple, and he moaned outright, sharp pleasure racing through his body so suddenly that Karamatsu immediately found himself growing hard. His breasts were so oversensitive now, it was painful and pleasurable to touch, and the heaviness was more of a fullness but he couldn’t bring himself to care. Masochistically curious, Karamatsu tugged on one of the nipple clamps, back arching with fierceness of sensations that assaulted him.

His mind was hazy, and he was barely conscious of the idea that the doctor could come back in; Karamatsu focused on jacking himself off, spitting into his hand to give him some sort of lubrication. Right hand tugging at his dick while the other played with his nipples, Karamatsu was barely thinking of his surroundings when there was a knock at the door to the room.

Startled, Karamatsu rolled off the table, shrieking in pain as the nipple clamps jarred against the surface on his way down. And his awareness was back, and with it, painful embarrassment. Ah, his brothers would truly call him painful if they saw him now! He desperately grabbed at his clothes, holding it over his crotch as he struggled to stand up. “Come in!”

“Thank you, Mr. Matsuno. Don’t worry if you are having embarrassing reactions, they are known effects of the substance you just took. It’s nothing I haven’t seen before, no need to be ashamed. Now, sit back on the table, and there’s one more inspection before we can bring you to the production room.”

Karamatsu did as ordered- it was much easier than thinking on his own, at least for the moment. There was no reason to have to overthink… He understood that now. The doctor was touching him again, but this time Karamatsu couldn’t summon the will to mind. “Aha, be careful, my nipples are my charm point!” He spoke with a smile as the doctor groped his breasts, not even bothering to hide the obvious pleasure he was still feeling. The man removed the nipple clamps, and Karamatsu ached with both relief and disappointment- the constant pressure and pinching had been arousing, especially when he tugged on it.

The doctor didn’t stop there, though. Instead of leaving Karamatsu’s chest alone, he returned to massaging the man’s breasts, rubbing and squeezing in a way that had Karamatsu sighing. And then, with an odd sort of disconnect from his body, Karamatsu realized he’d started lactating- when the doctor’s squeezing had neared his nipple, a sort of dribbling wetness had been produced, milk leaking from the area.

Oh.

“Oh is correct. You’ve developed beautifully. Now that you’re a confirmed producer, you’ll get paid the proper amount and can start working.”

A producer. Karamatsu felt more like a cow. But he was aroused and something in him desperately needed to be milked, so he only nodded his head rapidly.

“Good boy,” the doctor spoke, and Karamatsu thought that maybe this wasn’t so bad after all.

The man took hold of one of his nipples rubbing it gently before squeezing, urging more and more milk out of Karamatsu’s body. It was slow at first, little trickles of milk running down his body, but there was nothing he could do but grip the table tightly and press into the doctor’s fingers in askance. “More,” he begged, “Please-” He was getting relief he didn’t even know he needed, the fullness in his breasts finally relenting.

“Such a waste,” the doctor murmured, ignoring Karamatsu’s pleas and following the trail of milk down Karamatsu’s body with his hand. “But we have to start the process before we hook you up. You’ll feel much better soon.” He moved to the other nipple, squeezing that one like he had the first, over and over until more and more milk constantly leaked in a stream. “Very good… Now, Karamatsu, follow me.” The doctor opened his kit once more, taking out a half face mask and putting it on before reaching out for Karamatsu. And like an obedient animal, he followed.

There was a door locked by an access code that he hadn’t even noticed before, and Karamatsu attempted to follow the man’s fingers as he typed out the code but he failed abysmally in even processing the numbers. They’d entered into a room, the air hot and damp and making Karamatsu sweat even with his lack of clothes. The door shut behind them, and Karamatsu was led further into the room.

He was already beginning to feel more disoriented, something Karamatsu attributed to the heat of the room. Sights began to blur together, but the doctor was kind enough to lead him by the arm when he stopped moving, bringing him up to a stool secured in front of an ominous looking machine.

Many machines, like a terrifying electronic line, spread out inside the room. It was much longer than it appeared. There were stools in front of the other machines too, some with people in them, hooked up and tied up, but some were empty. Karamatsu faintly remembered two weeks ago, when they mentioned they were ‘still looking for new employees’.

His hands were tied behind his back and Karamastsu’s legs were attached to the bottom of the stool, but the longer he spent in this heat hazy room the less he could bring himself to care. The less he could focus. All he could think about was the burning sensation left on his skin wherever the leather of the straps touched him, or the aching sensation in his chest from a milking left unfinished.

The doctor attached some sort of suction implement to each of his breasts, something Karamatsu placed as a milker- he was attached to a milking machine. He was livestock- The realization hit with startling clarity, but he inhaled and the heat of the room (and did it smell sweet) invaded him and the thought was dulled.

He didn’t even notice when the doctor left, but he did notice when the machine started up. Constantly pulling, constantly sucking at his breasts and taking all the milk he produced down into itself, Karamatsu found himself aroused with each pulse of the machine, his mouth hanging open as he arched as much as he could, letting the machine control his body.

It wasn’t enough to get him off, and Karamatsu only now realized he wouldn’t be able to touch himself with his hands tied up like they were. He rutted against the stool shamelessly, thrusting his hips forward in an attempt to rub his dick against the fabric of the seat.

He couldn’t remember being this hard before. He couldn’t remember what he’d been doing before.

The milking seemed to last and last, but eventually the sensation in his breast turned to pain as the machine tried to take more and more from him when he had no more left to give. Eventually, one of the guards in the room (had they always been there?) walked over and stopped the machine, detaching the breast pumps from Karamatsu’s chest afterwards. He looked at the guard feverishly, whining with uncontrolled need.

“What’dya want?” The guard’s voice was muffled by the mask the man was wearing. Karamatsu couldn’t quite understand what was being asked, but he jerked his hips forward. “Ahh, first time.” He felt the stool being shifted and turned, and now he was facing towards the guard. He tried to look at the man’s features, but they only blurred together. “I’ll get you off if you blow me. Sound fair?” Karamatsu wouldn’t have been able to respond, but the guard was already unzipping his pants, pulling out his cock and stroking himself lazily. “Come on. Put that mouth to work. Not understanding?” He stroked his dick, then looked pointedly at Karamatsu’s own erect member. “Me, then you.”

Very unsure of what he should do- Karamatsu felt memories of the time he’d stolen and watched Osomatsu’s porn rise to the surface. That woman had given the man a blow job… This wouldn’t be much different. So he brought his mouth to the man’s dick, licking at the head cautiously. But the haze in his head was making him careless, and soon Karamatsu was laying open mouthed kisses to the guard’s dick, sloppy and trying his best before he realized he’d actually have to take the man inside him. Something inside of him wanted to be revolted. But he also couldn’t care.

But the guard was growling in impatience, and he grabbed Karamatsu’s hair and pulled his mouth forward, and it was all he could do not to bite down because he knew that was bad, but even now he could still feel his teeth touch skin and he was being forced off. “Don’t use your teeth!” The guard hissed, but he was moving in again so Karamatsu just opened his mouth and let the guard fuck it, the promise of his own cock being touched enough to have him controlling his actions.

“Keep your mouth open.” The guard pulled out once more, stroking himself the last few times before he came all over Karamatsu’s face and in his open mouth, but Karamatsu just accepted it blearily.

“That’s good… You’re hot like that.” He was hot… Another compliment. But mostly he just wanted to be touched. “Alright- if you want me to touch you, you have to moo. Come on, cow.”

Karamatsu didn’t understand what the point was, but he was so aroused it hurt. So when the guard wrapped a hand around his dick, he gave his best effort, mooing like the cow he was. It didn’t take long for him to cum, eyes shut and spilling himself into the hand of the Guard. The man wiped it on Karamatsu’s arm before moving to untie his hands and feet. “There. Now we go.”

Karamatsu couldn’t stand when he was finally released, legs trembling as he tried and fell to the floor. So he was on his hands and knees instead, but he couldn’t care. Not at all.
He was led into another room where he was washed off and cleaned by some other worker, and then he was given his clothes back and the doctor was entering.

Karamatsu felt a bit better now, head clearing up- but his mouth was as dry as cotton. The doctor handed him a glass of water, and he quickly drank it.

“So, how are you feeling?” Karamatsu made an indecipherable noise. The doctor pressed onwards. “Good? Do you remember what you’ve just done?”

“I….” He tried to remember. He remembered pleasure, and it was hot….

“You’ve just worked a hard four hour shift. You have that?”

“I’ve just worked a hard four hour shift.” Yes, that sounded right. Karamatsu felt more like himself already. “Ah, heat, my only enemy! Truly a great force to match….” He trailed off, thought suddenly disjointed. “Yes, I’ve worked a hard shift.”

“Good. You enjoyed it though, didn’t you?”

“Yes! I did enjoy it.”

“And so you’ll come back. You don’t really want to tell anyone the details of your job.”

“I’ll come back,” Karamatsu promised, “My brothers wouldn’t understand the details of my job.”

“You have brothers? Of the same body type as you?”

“We’re… sextuplets.”

“How interesting. Well, you’re all set here, Mr. Matsuno. I hope to see you here tomorrow.”

“Of course! Karamatsu Matsuno never loses track of time! It is merely one enemy for me to conquer.”

Notes:

if i do,theres a lot of ways i could take this. all the matsunos could become cows or something similar. Bull!Oso and Chorobaatsu....
the 'company' could get caught out and karamatsu's bros have to deal w/ their now cow brother.
