Chapter Text

There were days when Robotnik would gladly watch the world burn rather than be its rightful ruler and unwavering overlord.

Usually, such days involved a string of small seemingly unimportant setbacks or accidents that compounded into something so mind-blowingly infuriating that he considered building the world’s biggest weapon of mass-destruction and ending it all. He had an explosive temper no matter the quality of the day, but on really bad days his outbursts could easily become destructive in the literal sense.

The setbacks that plagued him ranged from minuscule things such as dropping his pen while trying to take notes on an important new project idea to more significant obstacles like one of his prototypes malfunctioning in the middle of a demonstration and severing some poor bastard’s finger off.

Most people took one look at him on such a day and scuttled away as fast as possible, knowing he was bound to tear into them if they got close enough to catch his attention. The only exception to this so far was his long-suffering assistant who was unlucky enough to be contractually obligated to be around him almost around the clock.

When he was in one of his moods, Robotnik resented this as well, and he made sure to do his best to make Stone crack under pressure, to push him past his limits and make him finally admit to not wanting to do it anymore. The only problem Robotnik had with this task was the fact that Stone had turned out to be a great deal more stubborn and resilient than he’d expected.

The calmness with which Stone received each insult and temper tantrum thrown his way made Robotnik wonder how Stone might look while being tortured in some inane way that unlucky agents were usually prodded for information when captured. Stone had to be good at it, Robotnik was sure of it. No one with that much patience and self-restraint could be lousy in interrogations. Out of the two situations, working for Doctor Robotnik was surely the worse one to end up in.

For some reason, Robotnik had yet to figure out a way to make the agent unravel and show the doctor a little bit of the real strength within him, even after a full year of Stone tagging along as his begrudgingly accepted assistant.

His failure to get a rise out of the agent when he was in a stroppy mood didn’t help the doctor manage his anger issues. On the contrary, it added to them, causing him to take out his frustrations on other people he knew he could grind down and humiliate with little to no effort. Usually that ended up being other agents and, if things got really bad, the higher ups that he was technically supposed to bow down to.

* * * *

It was safe to say things were currently pretty bad. Instead of just one bad day, the whole week was shaping up to be a series of very bad, no good, completely fucking terrible days, and it was only Tuesday.

It had all started with one of his control gloves short-circuiting on Monday morning. It caused the glove to electrocute him painfully until he managed to rip off the offending accessory and deactivate it for maintenance.

The incident had immediately made him grouchy and, perhaps more importantly, caused a snowball effect of bad by preventing him from working on his latest prototype in accordance with his planned schedule.

Stone had attempted to appease him with a well-timed latte decorated with immaculate art that depicted one of his egg-shaped drones. It had been a valiant but unsuccessful effort, because Robotnik had still been in pain due to the lingering cramping of his hand and the general irritation of having to give up on his plans.

Therefore, Robotnik had taken one look at the agent and the coffee in his hand and proceeded to berate him thoroughly for his mere existence on the planet as well as his lack of observational skills because how could Stone not see the obvious fact that his cramping hand was in no state to hold onto anything right now?

To his credit, Stone had at least had the sense not to point out that the doctor did in fact have a second hand as well, and that it was perfectly functional at the time. The only indicators that Stone had been affected at all by Robotnik’s outburst were the slight downturning of the sides of his mouth and a flash of disappointment in his eyes that the doctor caught due to how close he stood to the shorter man.

“Get out of my sight,” Robotnik had growled at Stone, clutching his hand to his chest and muttering about stupid assistants before turning around to get to work fixing up the malfunctioning glove.

From there, things hadn’t improved during the rest of the day. An influx of emails distracted the doctor from his work, prompting him to yell at Stone for failing to delete them immediately as well as threaten the destruction of his computer and the federal government itself.

At that moment, he hadn't given a damn about the fact that his funding was directly dependent on his cooperation with them. It was no surprise then that the doctor had been in a terrible mood the rest of the day and snapped at Stone whenever the agent appeared by his side with something to tell or simply holding another coffee.

* * * *

On Tuesday, Robotnik felt vicious right from the moment he woke up from his normally so refreshing three-hour sleep. He had spent most of the night working on the project he’d been unable to focus on the previous day due to his malfunctioning glove.

Leaving his mobile laboratory on a day like this was not ideal for anyone, least of all the people who would have the misfortune of running into him. His entire being radiated hatred at the world as he stalked the hallways of the government compound he was forced to frequent for countless meetings and endless bureaucratic nonsense.

In perfect accordance with Murphy’s law, the next very bad, no good incident occurred at that very moment. He was rounding a corner on the way to Commander Walters’ office when he collided directly with a person walking in the opposite direction.

The impact very nearly sent him flying on his behind on the floor, but by some miracle he managed to only stumble backwards before catching his balance. That was at least a lucky break, because there would have been casualties had he truly been toppled over by some government rube.

Stone, who had been trying to keep pace with the doctor’s long strides as usual, was there in no time, rather forwardly putting his palm on Robotnik’s back to stabilise him just in case. The only thing saving him from the doctor’s ire was the fact that he had someone else to blow up at right then.

His face twisted into an expression of unadulterated rage as he jabbed a gloved finger at the flabbergasted idiot in his way.

“You know, I ought to vaporize you in this instant, you pathetic excuse of a government dog. My status here outranks yours by such a margin that you don’t even exist to me. You will die and no one will remember you, because you. Don’t. Matter.”

With that, he darted forward with outstretched arms, wrapping his fingers around the man’s neck in a vice-like grip. For a few wonderful, cathartic seconds, he felt the man’s airways constrict satisfyingly under his gloves and watched terror replace confusion in his widened eyes.

Then, to his disappointment, he felt a pair of strong arms wrap around his midsection from behind, insistently pulling him away from the target of his attack. His assistant was deceptively slight in his size based on the ease with which he dragged the raging doctor back, effectively preventing him from committing murder.

”Unhand me, Stone!” Robotnik hissed, sharply jamming an elbow at the agent in an attempt to get him to relent. Stone’s combat experience came in very handy in such situations, so he was able to block the move enough to maintain his hold on the doctor.

Robotnik was mostly upset at the lost opportunity to inflict some real pain because Stone pulling him back gave the open-mouthed moron time to slink out of his grasp and reach. Robotnik growled in frustration and glared daggers at the nameless government lackey.

”What the hell? You’re fucking batshit insane!”

The doctor wasn’t going to argue with a factual statement, but he was still furious enough to flash the guy a wholly malevolent grin.

”Oh yes, completely, and I’m going to make your life a living hell,” he promised, nodding slowly while he worked on prying Stone’s arms off himself. His assistant reluctantly loosened his hold on the doctor once he stopped clawing for the man’s throat like a rabid animal. His humiliated victim was already running away though, more or less sprinting in the direction he’d come from.

Robotnik shot Stone a pointed glare to signal that he wasn’t going to stoop down to the level of someone so not worth the effort, so there was no further need for intervention. He did squeeze his hands into fists though, gazing longingly after what he knew would have been a wonderful opportunity to let off some steam.

“Sorry, sir, but killing him here and now would have unpleasant consequences for you,” Stone said, his eyes meeting Robotnik’s when the doctor turned to his agent with a disapproving look. It was unlike Stone to get so directly involved in the doctor’s business with other people, and he didn’t appreciate being interrupted.

“Stone,” Robotnik said, low and cold, his full attention now on his unhelpful assistant. “If you ever prevent me from using my authority over these dimwits and jackasses again, I’m going to ensure that any career you have hoped to build is erased from existence.”

Stone nodded calmly like the threat was nothing new, but he didn’t vocally promise to never do such a thing again. Feeling antsy and dissatisfied, Robotnik huffed and grabbed Stone’s tie with one hand, using it to yank the agent closer so he could really emphasise his words.

“I want you to find out his information and background and get him fired to high heaven.”

That, on the other hand, was the kind of thing Stone had no qualms about handling for the doctor because it could be achieved without damage to their reputations. Smiling a little despite Robotnik’s persistent anger, Stone nodded. “Of course, Doctor.”

* * * *

On Wednesday, things escalated further. Robotnik had fixed his malfunctioning glove by Monday afternoon, but even days latere there seemed to still be some lingering tension in his hand, causing it to spasm occasionally. The sensation drove him crazy, and paired with the laundry list of tiny little inconveniences that kept coming, he was still not doing any better mood-wise.

For example, for some inexplicable reason, Stone’s shoes suddenly squeaked in a way that constantly grated on his nerves, and he snapped at the agent to go change his shoes unless he wanted to be thrown out of the lab. Stone went without protest, but Robotnik continued to find things around him that broke his focus.

By the afternoon, Stone had a twitchy, explosive Robotnik on his hands once again. The worst part was that they had been summoned to some relatively important meeting about potential budget decisions which could obviously directly affect the doctor’s work. Robotnik avoided acknowledging the existence of the meeting up until Stone simply wouldn’t let him get away with it anymore. The clock was ticking.

After Stone sidled up to his chair for the third time, trying to be polite and nonchalant about it and failing miserably, Robotnik couldn’t take it any longer. He threw his hands in the air and groaned loudly. “Fine! Fuck, fine, yes, the meeting. Go away, Stone, I’ll be ready to go in ten minutes.”

* * * *

Miraculously, they ended up only being five minutes late to the meeting. Robotnik flung open the door of the conference room with a dramatic flourish, strode in without a word, and took a seat with his face already indicating pure disinterest. Stone quietly closed the door behind them before sitting down next to the doctor as usual, focused on observing the room.

Robotnik tapped the table in front of him impatiently while pretending to listen to whatever was being said in the room. He cared about his funding in the sense that he needed it to progress his projects as well as his secret plans that even the government wasn’t aware of. That didn’t mean he had to enjoy the meetings, of course.

What felt like an eternity later, Commander Walters finally turned to Robotnik and requested him to speak about his next proposal. Robotnik sighed and rolled his eyes. He didn’t like explaining his ideas to these people. They had no imaginations, not to mention any real intelligence to speak of.

“Agent Stone,” he said, gesturing for his assistant to do his part. Stone nodded and placed a disc-shaped hologram projector on the table so that Robotnik could demonstrate his designs.

Robotnik clicked a button in his glove to activate the holograms, launching into a long-winded presentation about what he wanted to build next. He gestured wildly with his hands as he spoke and manipulated the holograms to show off details he’d added to them, skipping through different perspectives and versions so quickly that most people in the audience had trouble keeping up.

It was all going astonishingly well from the doctor’s point of view, at least until he was interrupted right in the middle of showing his most ambitious and technical idea. The most embarrassing part was that the interruption came from his very own assistant who was definitely not meant to open his mouth during Robotnik’s speech.

Robotnik paused and turned sharply towards Stone, his eyes widening incredulously.

“Did you just sneeze?”

Stone grabbed his own nose and fought back another sneeze before nodding sheepishly. “Sorry, Doctor—”

Robotnik slammed his palm into the table and stood up, his eyes glinting with a manic anger.

“Agent Stone, perhaps you’ve forgotten, but you are here only, and I repeat, ONLY here as a somewhat useful tool to hand me things and close the door behind me. You are not here to participate, and the mind-boggling fact that you think it’s A-OK to interrupt me, ME, in the middle of demonstrating my genius is, quite frankly, a new low, even for you!”

He paced around as he spoke and closed in on the agent towards the end of his spiel, jabbing a gloved finger in Stone’s face. He was tempted to grab the agent and shove him into a wall for good measure, but even just this verbal outburst was enough of a shock to everyone in the room that he managed to stop himself.

The look in Stone’s eyes was an odd one, almost defiant, which Robotnik was certainly not used to. He leaned down with his shoulders hunched, gritting his teeth together.

“Wipe that fucking look off your face, Agent,” he snarled.

“Doctor, please, could I request that we get back to the presentation?” Walters suggested, looking somewhat pained. “I’m sure the agent is very sorry for interrupting you.”

Robotnik glared at Walters too, but bit his tongue because he knew it would be a hassle if he blew up at the hand that fed him quite so blatantly. He glanced back at Stone and drew a slow breath before taking a seat in his chair again. The way Stone stared at him bothered him. It was like he could physically feel the agent’s gaze on the side of his head. That feeling made it more difficult to get back to his presentation, but he pushed forward despite wanting to storm off and flip off every last one of the fools gaping at him.

The rest of the day, Robotnik sat hunched over his work and ignored his agent’s attempts to offer him coffee or suggest a break. He felt off his game and rattled. He couldn’t help thinking of the lab’s self-destruct button that was located next to the circuit breakers, momentarily fantasizing about the satisfaction of hitting it hard.

* * * *

On Thursday, Robotnik witnessed something unexpected.

He had been holed up in his lab all day, working away since he finally was able to without regular interruptions. He had even accepted his daily coffees from Stone, though somewhat begrudgingly, and only offered the agent a small grunt as a thank you without looking in his direction.

Naturally, there had been no comment from the agent, but Robotnik could still sense that Stone was not his usual self either. It seemed like the terrible week was in fact affecting both of them, even if the agent was eons better at hiding his frustrations.

Even the doctor had to admit to being human sometimes, however, and give in to the annoying basic needs of his body. Therefore, he took a small break to get out of the lab just as the sun was setting outside, frowning in confusion at the sight of his agent being outside as well. Stone was standing there with his back to the doctor, engaged in a lively conversation.

Robotnik did not recognise the man Stone was chatting with, but he saw immediately it was another agent from the way he was dressed. Suspicious, he approached the two men and stopped to stand behind his assistant, looming over Stone’s shoulder and giving the other agent an unsavory look. He was satisfied to see the unfamiliar agent’s face switch to an expression of trepidation.

“Agent Stone, having fun, are we?” As he spoke, voice purposefully casual, he slapped his palm onto his assistant’s shoulder and side-eyed him.

There was no nervousness in Stone’s eyes when he met the doctor’s gaze. Instead, he let out what sounded like a put upon sigh and nodded.

“Just taking my daily break. They’re in my contract,” he said equally casually, his tone carefully controlled. Nevertheless, Robotnik detected an attitude in the way Stone’s gaze lingered on him, as if daring him to prod further.

Robotnik made a face and shifted his attention back to the third person present, looking him over slowly.

“While you’ve been out here fraternizing, I have been sacrificing my precious time inventing new toys for you imbeciles. Oh and I don’t recall requesting a second assistant, by the way, so I’d like to know what the fuck you think you’re doing this close to my lab.”

He tightened his grip on Stone’s shoulder minutely, narrowing his eyes at the other agent.

“Mr. Robotnik—”

“Doctor,” both Robotnik and Stone interrupted immediately, making the agent stutter and then clear his throat before trying again.

“Doctor Robotnik, we were just chatting about, well, you know, the work and its… Uhh. Downsides.”

Robotnik grinned maliciously. “Oh, the work and its downsides, hmm?” he mocked, pausing to click his tongue, “I’m sure you know so much about the concept of work with that pathetic marble-sized brain of yours.”

The agent shook his head and opened his mouth again to respond, but Stone was faster. He placed his hand on the doctor’s wrist, turning towards him and drawing his attention once more.

“Doctor, allow me.”

Robotnik stared at his assistant in disbelief, not quite willing to accept that this was the third time Stone was interrupting one of his dressing-downs. His ultimate goal had been to get his agent away from this snooper, so he was somewhat pleased to have Stone’s attention back on himself. Intrigued despite his annoyance, Robotnik waited for Stone to continue.

His fingers still curled around the doctor’s wrist, Stone looked back at the other agent. “We’re very busy at the moment, and the Doctor hates interruptions. His work is also highly confidential, so it’s best if you take your leave now.”

Robotnik eyed Stone, a little disappointed by the lack of heat in his tone. Always so professional. He himself wanted to see the fear in the other person’s eyes when he intimidated them. Then again… perhaps it was nice to not have to waste his oxygen on another one of these government mutts for a change.

Robotnik paid no mind to the other agent as he headed off, instead focusing on watching Stone’s face with interest.

“I want you back inside, now,” he said after a moment, snatching his wrist out of Stone’s grasp before turning on his heel to stalk back to the lab.

Chapter Text

The second the lab’s door closed with a soft click behind them, Robotnik turned around again, ready to launch into another lecture about Stone’s behavior. The way the agent moved into his personal space without waiting for him to speak gave him pause, however.

“Ivo,” Stone said, and suddenly Robotnik could only manage an incredulous wheeze.

“You can’t call me that.”

Stone sighed, looking exasperated, and moved ever closer still, making Robotnik frown at him from above.

“What’s gotten into you?” Robotnik murmured, bringing his left hand up to massage it with his other hand, because the irritating muscle spasms still bothered him.

He froze when Stone put a hand over his, replacing the doctor’s gloved fingers with his bare ones to massage his palm. Robotnik blinked and suddenly felt his shoulders relax, realizing he had been hunching them unconsciously again.

“Just let me,” Stone said, giving him that horrible wide-eyed and genuine look of eagerness and determination.

Robotnik stared and contemplated snatching his hand away again, but the rubbing motions Stone was making were too pleasurable to resist. Letting his resolve crumble just a little bit, he sighed and closed his eyes.

“I hate this fucking place, Stone. They’re all idiots.”

With his eyes closed, he felt rather than saw the moment Stone shifted forward, his breath ghosting across the doctor’s neck.

“They are,” Stone agreed, brushing his lips against the corner of Robotnik’s jaw, and the doctor suddenly felt like he had lost the ability to breathe. He allowed himself to lean forward and rested his forehead against Stone’s shoulder.

“You’re so tense. You’re not at your best like this.” They were brave words from the agent, but he was clearly willing to take all kinds of risks at the moment.

“I could fire you for that,” Robotnik said quietly. He tilted his head slightly to allow the agent to mouth at his throat more, a small groan espacing his mouth. “I should fire you.”

“Stop with the threats for now.”

Indignant, Robotnik snapped his head up and glared at Stone. His agent didn’t look nearly worried enough for his liking.

“Do I need to remind you that I am in fact your superior, Agent?”

Instead of faltering and backing off, Stone looked up at him with an annoyingly smug smile playing on his lips, his hands giving Robotnik’s waist a small squeeze. The doctor glanced down quickly, wondering when the agent had grabbed him since it had apparently slipped his notice.

“Come on, Ivo,” Stone said, his eyes dropping to Robotnik’s mouth briefly, making the doctor’s brain short-circuit. He wanted to give Stone’s chest a good push with both hands and yell at him for his insolence, but instead he found himself grabbing the agent’s suit jacket with one hand and his tie with the other.

Stone didn’t seem to mind as he stood up on his tiptoes, boldly leaning in to brush their lips together. The almost nonexistent kiss shook Robotnik from his daze. With a growl of frustration, he yanked at Stone’s tie and crashed their mouths together again, this time properly. He hated it when people did things halfway — what was the point anyway?

Clearly surprised by the doctor’s sudden enthusiasm, Stone simply stood there for a few seconds before his brain seemed to come back online. He allowed Robotnik to push him backwards into the nearest wall, humming softly while his mad scientist of a boss kissed him with abandon.

Robotnik was too focused on tasting Stone and drawing lovely sounds out of his throat to pay attention to the agent’s hands sliding under his coat. Stone squeezed his waist briefly again and then grabbed his ass in a way that forced an embarrassing shaky gasp out of Robotnik.

He could feel his face flushing and hid it in the agent’s neck, digging his fingers into Stone’s shoulder with a grumble.

“Adorable,” Stone murmured in his ear, squeezing with his hands again and rolling his hips forward simultaneously, making Robotnik short-circuit a little once more.

“Stone,” Robotnik huffed, unsure what tone he was even going for.

With a shocking show of strength, Stone pushed himself off the wall and switched their places, pressing his hands against the doctor’s chest to hold him in place, just in case. He then had the nerve to grin at Robotnik’s shocked expression before leaning in to kiss him slowly.

“Stay there,” Stone said into his mouth, biting at his lip lightly before trailing his lips down to the doctor’s throat again. Robotnik breathed heavily and wondered how on earth he was allowing this to happen, or how he felt so unable to tell Stone to fuck off and get his hands off him.

His racing thoughts came to an abrupt stop when Stone bit the side of his neck sharply, making him smack his head into the wall a little harder than would have been comfortable.

“Gorgeous,” Stone said against the base of his throat while his fingers worked their way to the front of Robotnik’s pants and undid his flies.

The doctor briefly thought if it was possible he now had a concussion because he found it extremely difficult to form a full sentence. Logically, he knew it was almost impossible, but few other things could explain the way his body was currently behaving.

Having undone the doctor’s pants, Stone began to lower himself to his knees, kissing his way down Robotnik’s body as he did so. Stone’s eyes had a completely novel teasing glint in them as he gazed up at the doctor, who in turn found himself panting slightly as he stared down at his assistant on his knees in front of him.

Stone proceeded to also gently slide the doctor’s gloves off his hands, placing them carefully on the floor far enough to ensure they wouldn’t be trampled. Robotnik allowed it, although he felt surprisingly naked without the power his gloves provided.

He understood Stone’s reasoning behind removing them as well, and he couldn’t help commending the agent for knowing that he would be uncomfortable risking the functionality of his most important accessory after the events of the past week.

Stone grinned, his face positively exhilarated as he palmed the doctor’s cock, stroking him to full hardness with pure admiration in his eyes. “Look at you,” the agent cooed, digging his fingers into Robotnik’s thighs while he eagerly guided his dick into his mouth.

Robotnik shuddered and instinctively grabbed at Stone’s hair, feeling his knees go weak momentarily when Stone’s hot mouth enveloped his cock. He didn’t even know how long it had been since the last time he had felt something like this.

“A-agent,” Robotnik panted, not knowing what else to say. He felt Stone’s soft wet tongue swiping across the head of his cock and down his shaft, his hips twitching on their own accord at the sensation.

Stone hummed as he got to work, using his tongue and his hands in such an expert way that Robotnik made a mental note to interrogate his agent about his past later. He had to have learned that somewhere.

It was embarrassing to think about, but Robotnik was in such a state of frustration and pent up energy, combined with his lack of intimate relationships in recent history, that he didn’t think he could last longer than a few minutes with Stone like this, swallowing him down with every bob of his head. Robotnik hated the fragile feeling of vulnerability.

“Stone,” he hissed, yanking at the agent’s hair, “Stone, s-stop…”

Stone released him with a wet sound of his mouth that itself almost drove Robotnik over the edge, and then pressed a hand into the doctor’s side to stabilise him against the wall, having spotted his somewhat shaky demeanor.

“Ivo, what’s wrong?” Stone’s voice sounded disgustingly concerned.

Robotnik growled and looked away, his face visibly flushed. “I… I’m afraid I’m close already,” he said, aiming for a haughty tone of voice.

Stone finally seemed to catch on, his worried expression melting away. It was replaced with a teasing look once more, and he stood up, leaning up on his toes to kiss the side of the doctor’s mouth and jaw. “Never seen you quite like this.”

Robotnik grabbed Stone by the jaw, indignation and irritation winning over his embarrassment.

“Agent, I’d be very careful if I were you,” he said slowly, doing his very best to ignore the way Stone ground their hips together downright disrespectfully.

“Hmm, hard to take you seriously right now,” Stone replied, bending down at the knees slightly to brace himself as he wrapped his arms around the doctor’s hips, effectively forcing him to wrap his legs around the agent as he stood up again.

Robotnik yelped softly, suddenly feeling the need to cling to Stone’s shoulders. The agent was clearly stronger than he looked with his fairly small build, although Robotnik hardly weighed much considering his current eating habits.

Once Stone had him lifted up with a secure enough grip, he turned around and made his way to the doctor’s workbench. It was littered with pieces of metal and other materials and tools that would definitely pose a health hazard if laid or sat on.

Stone set Robotnik down on the edge of the workbench before sweeping his arm across the surface, sending the scraps and tools flying across the floor. Robotnik grabbed a fistful of Stone’s jacket and slapped him across the face.

“Stone! What have I said about fucking with my work?”

Stone’s eyes fluttered at the sudden flash of pain, but instead of anger or disapproval, his eyes were dark with want as he met the doctor’s gaze.

“I won’t fuck with your work, Doctor, promise,” Stone breathed, closing in on Robotnik again as he stepped between his parted legs and caught his lips in a messy, uncoordinated kiss.

“I’ll just fuck you, sir.”

Robotnik groaned, feeling his cock twitch almost painfully at Stone’s words as all his blood rushed in the same general direction. Stone seemed pleased by it, his hips grinding forward instinctively as he gripped the doctor’s thighs.

Robotnik snarled: “Hurry the fuck up then!”

He clawed at the front of Stone’s shirt, tugging at buttons with shaky hands that refused to follow the orders sent by his brain. With a growl, he undid Stone’s tie and flung it across the room, ripping the rest of his shirt open without much finesse. Next, he pushed Stone’s blazer off his shoulders, prompting a small grin from the agent who quickly shrugged off the shirt as well.

“Now you,” Stone murmured while Robotnik raked his fingers across his agent’s chest, feeling the firmness of muscle and warmth of blood under his skin and growing almost drunk with it.

Stone grasped the doctor’s left arm and patiently guided him to slip the coat off his left side before repeating the procedure on his right side until Robotnik’s coat was free to fall off his shoulders.

Imitating the doctor’s earlier behavior, Stone then hastily worked on unbuttoning Robotnik’s long black shirt. The moment one of the buttons got caught, Stone grabbed the two sides of the dress shirt and then tore it open, his now bare arm muscles bulging impressively with the movement.

Robotnik’s eyes widened as he took in the sight of Stone like this, more uninhibited than perhaps ever. He admired the expanse of bare skin and dark chest hair that rose and fell in time with Stone’s breathing. Why had he never realised just how pleasing to look at his agent could be under those plain suits he always wore?

“Stone, you need to stop wearing shirts immediately,” Robotnik said in his usual demanding tone. Meanwhile, Stone focused on maneuvering the doctor out of his pants and boxers. Unsurprisingly, Robotnik didn’t provide much help, simply shifted his hips the way Stone needed him to and extended his legs one by one to allow the agent to remove his shoes as well.

“Right,” Stone replied, his voice uncharacteristically hoarse. He tossed the doctor’s shoes on the floor and then admired the sock garters his boss apparently wore under his well-tailored pants, inching a finger under the strap of one and letting it snap against Robotnik’s calf.

The doctor twitched slightly and wrapped one hand around the base of Stone’s throat. “Get on with it before I change my damn mind.” He was defaulting to using threats again, but at least it got the agent moving, his fingers tearing down the garters and socks in no time.

Finally, Stone grabbed Robotnik’s hips and pulled him forward on the workbench, kissing him hard while trying to press their bodies together as much as possible. Robotnik growled, digging his fingers into his agent’s shoulder blades hard enough to draw a small groan from Stone.

For a moment, Robotnik got to enjoy the heat of Stone’s bare skin against his and the tickling of his beard against his face and throat while the agent lavished him with wet kisses. Then, Stone had to be irritating again by pulling back and leaving him with one last nip at his bottom lip and a murmured command to stay still.

Thankfully, Robotnik didn’t have to do so for long, because he barely had any patience left in him at all. As soon as Stone returned, Robotnik locked his legs around the agent’s hips and tugged him close to mouth at his clavicle.

“Stone, I don’t fucking have all day, do I?!”

At that, Stone’s mellow demeanor disappeared. Apparently, there was a point where even the most long-suffering assistant couldn’t take any more.

“Fine. Alright, then,” Stone breathed, his voice lower than anything Robotnik had ever heard before. He took a step back, giving Robotnik a brief view of his nicely toned upper body again, and then dragged the doctor off the workbench with a rough grip on his thighs.

Robotnik opened his mouth to protest, but then Stone was spinning him around, pushing his head down into the surface of his own workspace while parting his thighs for better access.

“I think I’ve seen enough now,” Stone said while Robotnik panted in shock at the sudden change, shuddering when the tip of his cock brushed the cold edge of the workbench.

Had this been anyone else in the world, Robotnik was certain he would have eviscerated them on the spot. The way Stone’s finger was teasing open his hole was too distractingly wonderful for him to continue that train of thought.

“You’ve been out of control these past few days, Doctor,” Stone continued, making Robotnik gasp and squirm his hips when he pushed his finger further and began teasing him with slow movements.

“Stone… lubricant… how…?” Robotnik asked, turning his head to look over his shoulder. His curiosity got the best of him, even now. Seeing Stone with that dark look in his eyes, fingering him with a look of intense concentration, made him almost forget what he was even asking about.

“A good assistant is always prepared,” Stone replied simply, meeting Robotnik’s eyes and then, as if it was not the most shocking choice possible, giving his ass a solid slap.

The doctor reacted with a moan that he could not suppress in time, pressing his forehead down against the workspace under him.

Like some sort of magician, Stone continued to draw embarrassing sounds from him with his fingers until he was breathing rapidly and squeezing his eyes shut, his entire body trembling slightly.

“Stone…” Robotnik murmured, more as a plea than an order for once.

The low hum that Stone let out in response sounded nothing like the docile agent the doctor was used to. With two hands, Stone grasped the cheeks of his ass and then, causing Robotnik to splutter at the utter filthiness of it, spat on him for added slickness.

“You need this,” Stone said as he lined himself up with the doctor’s stretched and slicked up hole, his other hand gripping Robotnik’s hip tight enough to leave a bruise. Robotnik whined in response, past the point of being verbal.

While he slowly bottomed out, Stone leaned over the doctor’s back so he could bite at his pale shoulder and let him feel his full weight. “Fuck, Ivo…”

Stone paused momentarily to give himself time to adjust to the heat and tightness of his doctor, sliding his palms down to press against Robotnik’s abdomen. For a few seconds, they both just breathe, Stone rubbing the tip of his nose into the nape of Robotnik’s neck and murmuring praise that he might otherwise scoff at.

Finally, after what felt like an entire eternity for Robotnik, Stone shifted his hips and began rocking into him, making Robotnik’s eyes roll back in his head. He scrambled for purchase before settling for gripping the edge of the workbench with both hands, pushing himself back against Stone with what he hoped wasn’t too obviously a mewl.

With a grunt, Stone straightened up and dug his fingers into his boss’s hips, starting to fuck him in earnest. His thrusts were harsh and quick once he established a rhythm, his strong hands holding the doctor firmly in place.

“T-that’s it… Look at you, Ivo…”

Robotnik couldn’t stop the desperate little sounds that left his mouth every time Stone’s cock slammed into him. He whined louder when one of the agent’s hands wrapped around the back of his neck, squeezing with the perfect amount of pressure.

“Harder, Stone,” Robotnik barked, his voice breaking slightly in a way that ruined his attempt at sounding commanding.

With a breathless chuckle, Stone obliged, ramming the doctor with force into his workbench and making sure to bury his cock fully in him with each snap of his hips.

The combination of pain and pleasure was more than enough to make Robotnik’s brain effectively shut down, at least partially. He simply keened and trembled at the way his agent filled him with each thrust, arching his back and straining his arms.

“You’ll come just like this,” Stone barked at him, shifting his hand from the back of Robotnik’s neck to the back of his head. He closed his fist in the doctor’s hair and shoved his head down with intent, simultaneously fucking into him while angling his hips for the spot that made Robotnik let out particularly desperate sounds.

“Just from my cock, Doctor, won’t you?”

Robotnik could already feel his orgasm building, his years of avoiding human contact and any kind of sexual release coming back to haunt him with a vengeance.

“S-stone,” he choked out, high-pitched and wrecked.

Stone gave his hair a tug in response, other hand bruising his hip with the strength of its hold.

“Yeah, say it… Say my name….” Stone clearly couldn’t resist a little self-indulgence. The way Robotnik moaned it out for his agent was something he would remember with both humiliation and heated desire.

Stone’s grip on his head tightened again and the agent murmured a string of curses in a low, gravelly voice, the rhythm of his hips faltering just slightly. Once he collected himself, he plastered the length of his body against Robotnik’s back again and sunk his teeth into the top of his shoulder.

“Ivo, come for me, sweetheart,” he breathed.

Robotnik didn’t need to be told twice at that point. He bucked his hips back against Stone who held firm in his position, and his whole body tensed up with a loud exclamation as he came, spilling his ejaculate across the edge and surface of the workbench.

Stone fucked him languidly through it, whispering words of encouragement into his ear while Robotnik felt every last drop of his come spurt out of him.

Once the doctor was completely spent, Stone kissed the back of his neck more affectionately than was perhaps warranted, and then stood up, his cock slipping out of Robotnik with a filthy sound.

His mind blank, Robotnik trembled in his position across the workbench, unaware of his surroundings until gentle but firm hands coaxed him backwards. He stood with shaky legs, his chest still heaving as Stone turned him around.

For once, there was no fight left in him. When Stone guided him down to sit on his knees on the floor, he went willingly without a word.

“I bet you feel better,” Stone murmured, cock already in one hand as he stepped closer and cupped the doctor’s face with his palm. Robotnik stared up at him in a dazed state of bliss, his mouth falling open immediately the second Stone guided his cock up to it.

With the doctor so pliant, Stone had no trouble grabbing the back of his head and thrusting slowly in and out of his throat, making delicious groaning and grunting noises as he did so.

“Beautiful, Doctor,” the agent commented, dark eyes fixed on Robotnik’s face. “Look at you with your mouth full… taking my cock down your throat, boss.”

Robotnik’s eyes fluttered and he shuddered, his own cock twitching despite being so overstimulated. He focused on watching Stone’s face with all his remaining energy, seeing the way the agent neared his climax as he claimed the doctor’s mouth.

“Ahh, fuck. That’s it…” Stone’s voice was ragged when he came with his cock halfway in Robotnik’s mouth, creating an obscene bump in the side of his cheek.

“Come on, let me see you swallow,” Stone breathed, combing his fingers through Robotnik’s hair while he tasted his for the first time.

Never one to back down from a challenge, Robotnik made sure to gather every last bit of Stone’s come on his tongue, showing off his full mouth for the agent before swallowing with satisfaction.

After finishing, Stone cupped Robotnik’s face with both hands and leaned down to kiss him, marveling at how utterly docile he was now.

Stone’s grin was awfully smug when he hooked his arms under Robotnik’s armpits and hauled the taller man to his feet, making sure to support his weight against himself.

“There we are… Alright, Doctor?” The agent was chipper all of a sudden, and Robotnik could simply groan softly, burying his face in Stone’s shoulder.

“I’ll get you cleaned up so you can get back to work,” Stone continued, sounding almost as if nothing out of the ordinary had just happened.

Robotnik wasn’t sure if he could go on living now, and Stone was talking about work… He settled for biting at Stone’s ear as a response.

Stone chuckled, realizing the doctor was further gone than he’d expected. “Or… maybe I’ll just take you to bed then.”

* * * *

On Friday, no one on the compound or near the lab knew how to react to the Robotnik they got to witness.

He was calm, something that would have been normal and expected for literally anybody else, but was unnerving and bizarre for him.

Even Walters seemed confused by his sudden change in behavior.

His assistant, on the other hand, seemed bolder than usual, standing closer to the doctor than was necessary and laughing audibly at his quips and sharp remarks.

Robotnik was still bound to become irate when someone got on his nerves badly enough, but it was noted by several people that he would tear into his unlucky victims with his usual vigor, only to then steal a conspicuous glance at his agent and share a brief, odd smile with him.

Chapter Text

After Stone had dealt with his persistent bad mood and frustration with such admirable dexterity, Robotnik saw his agent in a completely new light. He still snapped at Stone occasionally and demanded absolute perfection from his personal assistant, but he was suddenly much more interested in observing and cataloguing each of Stone’s reactions. 

In secret, Robotnik had even made up a little game for himself to see exactly what made the agent tick and what ways he could use to get under his skin. Stone was extraordinarily competent in his job, so it was no small feat to get his calm exterior to break. 

Robotnik loved challenges, though, so he was endlessly entertained by the way he could always elicit something new and interesting from Stone, sometimes only with the smallest tweaks to his variables. Since he was a serious scientist, he took it upon himself to design a few delicate experiments with which he could establish the rough scope of his agent’s patience.

Experiment A: Rapid succession of annoyances

• H0: Providing Stone with a rapid succession of annoying stimuli has no effect on his level of patience.
• α = 0.01

So far, it was clear that Stone could be sufficiently provoked by Robotnik’s mood being terrible for a prolonged amount of time. It had previously taken several days for Stone to act on his desires to calm the doctor down, however, which Robotnik considered less than ideal. He didn’t want to spend a week losing his mind each time he wanted a lovely reaction out of his sycophant. No, there had to be a way to fast track the process, and Robotnik was going to discover it. 

Naturally, Robotnik could think of ways to pick at his assistant’s patience. He did it on an almost daily basis without even trying, after all. Not all of his attempts were successful, clearly, because otherwise he would have cycled through perhaps a dozen more assistants by now. Stone was different, because Stone stayed. Stone was also difficult.

Ivo Robotnik was nothing if not good at fucking with people, so it didn’t take him long to come up with a few particularly irritating things he could put his assistant through, just for his own amusement. 

Pleased with himself and his excellent plan, Robotnik waited until it was a Friday evening and Stone was clocking out to go spend his weekend doing… whatever it was his agent did on the weekends. 

The agent had watched his doctor work away the whole day, as per usual, supplying him with coffee at regular intervals and checking in on him as needed to confirm proposed meetings and such. Robotnik was his usual self, the usual being abrasive and hard to handle, but not excessively so. Stone certainly suspected nothing, based on his relaxed behavior, his smiles genuine as he obeyed whatever casual command Robotnik barked at him.

When Stone finally clocked out for the night, dutifully saying his goodbyes to the doctor before heading out of the lab, Robotnik simply grunted softly at him in acknowledgement. 

He waited in his seat until the agent was definitely out of the mobile lab and then pulled up a live feed of the cameras that gave him a 360° view of the outside. With interest, Robotnik watched the agent put on his helmet as he walked to his motorbike. When Stone finally took off, the doctor smiled mischievously to himself and set his plan in motion.

* * * *

At two in the morning, Robotnik took a break from his spontaneous coding session which he’d unexpectedly become rather absorbed in while passing the time. He leaned back in his seat and pulled up the live feed of the lab’s outside again. Then, he pressed a few buttons in his gloves and watched another window appear in the hologram, showing the agent’s personal number which he was currently dialling. 

Stone only took thirty-four seconds to pick up. Not great, but not totally awful. Robotnik made a mental note to do this more often regardless, to ensure that Stone would learn to answer faster. 

“Doctor?” The agent’s voice sounded gruff and hoarse, indicating he’d indeed been fast asleep. 

Robotnik paused to consider Stone’s voice, somehow caught off-guard by its quality like this. Could it be that he had wanted to hear Stone’s sleep-addled tone? He also couldn’t help making the important observation that Stone was spending his Friday night at home, sleeping like he had nothing better to do. Somehow Robotnik had half expected him to be out, perhaps sitting in a bar somewhere. Realizing he was allowing himself to be distracted from the plan, Robotnik pushed the thoughts away.

“Agent,” he replied casually, “I need you back in the lab immediately.” 

He could hear Stone yawn over the line and then make a soft humming noise that tickled a part of Robotnik’s brain. 

“Oh… Has something happened? Are you alright?”

Rolling his eyes, Robotnik picked up a pen from his console and twirled it in his hands, starting to feel antsy. 

“That’s an order, Agent. You may be off the clock but your duties include being on call.”

Robotnik couldn’t be sure but he had a feeling Stone was smiling when he responded: “Of course. I’ll be there in a moment.”

As soon as the call disconnected, Robotnik turned back to his live feed from the security cameras outside. He locked down the doors of the mobile lab with a few clicks and temporarily removed Stone’s access rights. 

Normally, the agent had the rights to access almost anything within the lab or connected to the doctor’s systems, though he might not have realized it. Robotnik had simply figured that if he was going to have an assistant, he might as well be useful, and Stone would be of no use to him if he couldn’t come in handy in a sticky situation. He hadn’t mentioned it separately to Stone since it seemed unnecessary.

As promised, it didn’t take Stone very long to get back to the mobile lab on his bike. Robotnik watched the agent park outside and remove his helmet, his expression worried as he hurried towards the entrance. Robotnik smirked, stroking his mustache with a thoughtful look while Stone made his way to the door and then stood there, clearly befuddled when it didn’t slide open for him.

Robotnik waited calmly for a minute or so, and then dialled Stone’s number again, watching the confused agent scramble for his phone.

“What the hell is taking you so long?” Robotnik asked, leaning back in his seat and crossing his legs.

“Doctor, there’s a problem… I can’t get inside.” Stone sounded endearingly stumped, perhaps even concerned. 

Robotnik scoffed at him, smirking briefly before schooling his face back to annoyance again, making sure he sounded authentic. 

“Of course you can, Stone. I’m sure you know how to use the door by now. Or… have you had a stroke and lost the last of your wits during these few hours you had to yourself?” 

Stone frowned at that, looking around before attempting to approach the door again. He then reached his free hand into his suit jacket, surprising Robotnik by pulling out the gun that he had only seen Stone wield in very rare situations. 

“Doctor, this seems off to me, are you sure you’re alright?”

Robotnik blinked at Stone’s earnest tone, a little taken aback by it. Of course, it was the agent’s job to act as his bodyguard when needed, but it still shocked him somewhat when Stone was so ready to jump to his defence. He was used to defending himself, after all.

“Obviously, Stone,” he said cautiously. What was the agent going to do, shoot a hole into the mobile lab’s wall to get inside? If he decided to do that, Robotnik would certainly fire him.

Instead, Stone chose to make his way carefully around the lab, seemingly checking each angle and spot for anything suspicious. Naturally, he found nothing out of the ordinary, because the whole thing was in reality orchestrated by the doctor, but Robotnik still suddenly felt a little less mischievous. He had no doubt Stone was ready to kill anyone who stepped in his way right now, and that was an undeniably powerful image. 

Swallowing, Robotnik cleared his throat briefly and pressed the necessary buttons to unlock the door and give Stone his access rights again, at least partially. He didn’t want to give him full access just yet. 

Once Stone had made a full lap around the lab to ensure there was no security breach, he inevitably saw the door slide open for him as expected. Robotnik could practically feel the confusion and concern radiating off the agent as he entered. Still, he didn’t turn around in his chair immediately, instead letting Stone approach him from behind. He watched as an intruder alert popped up on one of his holoscreens, indicating the security badniks were being activated.

“Doctor, this is kind of strange—” the agent began from behind his back, and Robotnik looked over his shoulder just in time to see Stone gasp and stumble before falling to his knees. 

Robotnik hissed sympathetically at the agent as he convulsed with pain due to the electric current running through his body, enough to paralyse but not intense enough to kill him on the spot.

“Oh dear,” Robotnik commented, flicking his wrist at the badnik behind Stone’s twitching form to dismiss it now that it had served its purpose. “Must have accidentally activated the security protocols.” Of course, Robotnik never did anything by accident, and if he did, he simply came up with a reasonable explanation why it had been his plan all along. He knew that Stone knew this as well.

Approximately a minute later, Stone collapsed onto the floor with a loud groan, his muscles finally able to relax. He was incapacitated for a moment, and Robotnik finally turned to observe him with a curious tilt of his head. Sprawled across the floor, panting and huffing, Stone was quite the vision. Robotnik couldn’t resist a small quirk of his lips at the sight. 

When the agent regained his ability to speak, he looked up at the doctor with a frown, confusion still written all over his face. “Doctor… Ah, what did you need from me?”

Robotnik bit his tongue to stop himself from chuckling, but he knew his eyes had taken on that tell-tale gleam of impish daring. He always enjoyed playing with people, but with Stone it was particularly entertaining. With an exaggerated gesture of thoughtfulness, Robotnik looked up and then waved his hand in the air, shrugging his shoulders slightly.

“You know what, Agent? I changed my mind. I don’t require your assistance anymore after all.”

With that, he turned around in his chair again, going back to the code he’d been working on earlier. He listened to the shuffling noise of Stone lifting himself off the floor as he typed, eyes fixed on the screen although he was almost hyperaware of the agent’s presence now. 

As expected, Stone wasn’t quite satisfied with his answer, not after being woken up in the middle of the night, locked out of his workplace, and then electrocuted with enough voltage to hospitalize a weaker person.

“Ivo,” Stone sighed, still sounding a little breathless when he appeared on Robotnik’s left side, doing that thing where his eyes drilled a hole in the side of the doctor’s head again. 

Robotnik hummed in response, fingers flying across the keyboard. Even when paying close attention to Stone internally, it was child’s play for him to type out lines of code without significant effort. With his peripheral vision, Robotnik could see Stone cross his arms in front of his chest. 

“Sir, you called me here at two in the morning, saying you absolutely need me here. How come that changed so suddenly?”

Robotnik held up a gloved index finger in Stone’s direction, signalling for him to stop talking and wait while he continued to type with one hand. He held the position for a few minutes, but Stone didn’t budge, so eventually he sighed deeply and turned to face his agent, eyebrows raised.

“Part of this job is to expect the unexpected, Agent. You should know that by now. I had an urgent need for you which was, like you can see, resolved before you could drag yourself out of bed.” He gave the agent a brief once-over with his eyes. 

“Urgent need,” Stone repeated slowly, staring at the doctor incredulously. 

Robotnik sniffed and gave a small nod of his head, standing his ground. “Yes, and now you’re bothering me. I’m working, Agent, can’t you see?”

Stone made a face, the way he sometimes did when he thought Robotnik was being ridiculous, and ran a hand through his short hair. “Uh huh.”

Robotnik turned back to his code again before speaking. “So why are you still here, Stone? Piss off.”

For a beat, the lab was completely silent, save for the sound of keys being tapped and the soft beeping of machinery. What Stone did next was admittedly rather surprising, as Robotnik had been sure he was making headway in cracking the agent now. 

Instead, Stone let out a deep sigh and disappeared from the doctor’s field of vision, wandering towards the door. Damn it, Robotnik thought. 

Thankfully, the doctor was the master of contingency plans, so as soon as Stone marched out of the lab, he pulled up the live feed from outside again, stroking his mustache thoughtfully. Despite the lack of an outburst from the agent, Robotnik could see frustration in his gait as he headed to his bike. That was something at least. 

With bated breath, Robotnik watched Stone walk up to his motorbike and pause to take in the sight of it. Robotnik could almost see the gears turning in his agent’s head as he processed what was wrong. A few seconds passed, and then Stone was turning on his heel and storming back to the lab. 

Oh here we go, Robotnik thought, snorting victoriously. He swivelled around in his chair just as the agent entered once more, his deep brown eyes immediately locking onto the doctor. 

“Ivo. Where’s my helmet?”

“You address me as your superior, remember?” Robotnik rolled his ankle around while watching Stone with a calm expression, shrugging his shoulders a little. 

“And how should I know, hm? Perhaps you misplaced it in your rush to get here.” His mustache twitched slightly as he spoke, and he suppressed a smile at the way Stone’s long-suffering expression turned darker.

“Sir. I didn’t misplace it.” 

Stone approached him with slow steps, his narrowed eyes scanning the doctor. 

In return, Robotnik met the agent’s gaze steadily while he walked closer. He tilted his chin up to maintain eye contact as Stone came to stand right in front of him. For a change, the agent was the one towering over the doctor, their usual perspectives reversed.

“Insolence, Stone. I’ll write you up.” Robotnik could hear the breathiness of his own voice and internally cringed at it. He was supposed to be above all that. But… Stone’s eyes had taken on that captivating gleam of hunger and fascination, just like the last time Robotnik had drawn out his more commanding side.

“I’m sure you will, Doctor,” Stone murmured, tongue darting out of his mouth to wet his bottom lip. Robotnik tracked its movement with his eyes and then nudged the tip of his right shoe into Stone’s thigh. 

Stone drew a small breath and then brough his hand up to cup Robotnik’s chin. “We both know whose insolence got us here.”

Robotnik felt his chest tighten a little, but he maintained his composure. He responded with a quirked up eyebrow and an unspoken Oh?

Stone leaned even closer and his other hand found Robotnik’s thigh, giving it a firm squeeze. “I know what you’re doing.”

Robotnik chuckled, proceeding to palm Stone’s groin with one hand in return. He could already feel a pleasing firmness there, and the growl that his agent let out at the touch was like music to his ears.

“You work for me,” Robotnik whispered, dropping his eyes to Stone’s mouth.

Stone nodded and smiled, and Robotnik found himself smiling back despite himself.

“Yeah, I’m here for your every need, Doctor.” His hand moved from Robotnik’s chin to the collar of his shirt, grasping it in a manner that was definitely not appropriate behavior for a subordinate. 

“And right now, you’re in need, aren’t you?”

Robotnik gave Stone’s crotch another squeeze, huffing softly. “Thanks for stating the obv—” He gasped when the strong hand on his collar wrapped around his throat instead, pushing him back into the chair. Stone’s grip was rough and unyielding, and Robotnik’s eyes widened automatically when he realiseed he actually couldn’t breathe.

“Aren’t you, Ivo?”

Stone loosened his grip just enough to allow Robotnik to speak. A little shakily, he said: “Yes, Agent.”

Stone nodded and hummed in satisfaction, the low sound of it sending a pleasing shiver down Robotnik’s spine. My genius pays off once again, he thought gleefully.

“On your feet,” Stone said, husky and demanding. 

Robotnik grinned up at the agent and gave his thigh another little shove with his foot. “Bossy.”

The way Stone hauled him up from his chair almost had him tripping and crashing into the agent. Lucky for him, Stone had already grabbed him by the collar of his shirt again and was dragging him towards the console. 

Robotnik made a surprised sound that left him feeling embarrassed, his face flushing as Stone shoved him into the console and bent him over it like it was nothing. The strength in those arms that he kept concealed under his unassuming suits was just as shocking for the doctor this time around.

“Careful, Stone, my outfit is worth more than your bike,” Robotnik hissed. Still, he arched into the way Stone shoved at his long coattails to push them out of the way and reached around his waist to undo his pants with swift movements. Next, Stone was roughly yanking at his pants and underwear to get them down around his thighs, leaving him fully exposed to the agent’s gaze. 

Robotnik expected to feel Stone’s fingers press into him next, or at least tease him like had done before. Instead, he was shocked to feel a severe full-handed slap on his bare ass cheek, his breath catching immediately. Unable to control himself, Robotnik moaned indecently at the pleasurable stinging sensation that spread across his skin. 

“I need my bike, Doctor,” Stone replied, rubbing his palm over the spot he had just smacked before doing it again, just as stern. “You wear these clothes to prance around and show off. What you need is someone to tear them off.”

Robotnik hissed a curse and squirmed under the agent’s touch, feeling a mix of indignancy and euphoria. The way Stone could have him admitting to things was unparalleled, even if some of the admissions only took place inside his head. 

“Stone,” he breathed, trembling slightly with each harsh slap of the agent’s palm against his buttocks. Stone responded with a throaty growl and then pinched his skin, drawing a shuddering curse out of the doctor. “F-fuck, just fuck me already, Stone!”

Stone chuckled in a dark voice, sliding a finger between Robotnik’s cheeks and teasingly pressing its tip against his hole, just enough to make him groan and crave more. 

“I believe getting fucked is a pleasure reserved for bosses who perform exceptionally.”

Robotnik scoffed and made a move to stand up so he could express his thoughts at his agent properly. Immediately, Stone placed a firm hand in the middle of his back and pushed down, preventing him from getting up. 

“What the fuck, Stone? I am exceptional. You know this. I’m always exceptional.”

Stone laughed, actually laughed at him, before landing a few more stern slaps on Robotnik’s already flushed and burning skin. 

“You’ve performed questionably today though, hm? Accidentally locking me out, electrocuting me, misplacing my helmet…” 

Robotnik growled and reached a hand down to stroke himself since Stone wasn’t doing anything of the sort. “Argh, you know those weren’t actual accidents, Stone,” Robotnik hissed, his ego winning out against his desire to be cunning and secretive again.

The agent grabbed a handful of Robotnik’s ass and squeezed so hard the doctor whimpered softly. Stone sounded smug as hell as he spoke: “There it is, Ivo. Beautifully honest. But I’m afraid I’ll need to discipline you anyway to make sure you understand the meaning of your actions.”

Robotnik opened his mouth to protest further, but Stone had already bent down and was filthily spitting at his exposed hole, rubbing his saliva in with a little appreciative rumble. He pushed only the tip of his finger in, nowhere near enough for Robotnik to feel satisfied, and then replaced his hand with his hot mouth, making Robotnik yelp at the unexpected sensation. 

“If you ever embarrass me in front of people again, like you did last week, I’ll bend you over the conference table and have you like this.”

Robotnik couldn’t help imagining it vividly, stroking himself faster while immense heat pooled in the pit of his stomach at the idea. There would be no coming back from such a scene. It would be the end of his reputation as a man of great power. And yet… his cock twitched almost painfully as he pictured it.

With obscene noises of his mouth, Stone licked and lapped at him, using his tongue to make the doctor’s legs tremble with the effort of keeping himself up. Robotnik moaned loudly, feeling his orgasm approaching as he continued to stroke himself vigorously. 

Right as he was reaching his climax, Stone’s hand wrapped around his wrist tightly and pulled his hand away from his leaking cock. 

“I don’t think so, Doctor,” Stone said, sinking his teeth into the fleshy swell of Robotnik’s ass as he pinned his hand down against the console.

“Fuck. Off. Stone, if I don’t come in the next five minutes, you’re fired,” Robotnik snarled, although he did nothing to try and push the agent off. 

With a sigh, Stone straightened his back and tangled his fingers in Robotnik’s hair at the back of his head, pulling him up to stand without much care for how painfully it stretched his scalp. 

“Alright then, if that’s how it is, sir,” Stone replied, wrapping his arms around Robotnik’s waist and pressing himself against the doctor’s back to hold him still in a firm embrace. 

Somewhat dizzy from the sudden change in his position, Robotnik leaned his head back and panted, letting out a breathy moan when Stone’s steady hand wrapped around his cock.

“Look at yourself, Ivo,” Stone commanded, biting at the back of the taller man’s neck as he began to tug at his cock with a rigorous pace. 

Robotnik forced his eyes open and looked down at the way Stone pleasured him, his mouth falling open slightly. “S-stone… ah… Please,” he gasped, almost delirious with his own desire, and certainly no longer in control of his words. 

With the way the doctor was, Stone only needed to jerk him off with determination for a minute or so before he was shuddering and spilling his load into the agent’s hand. 

“That’s it… There’s my beautiful, greedy man,” Stone drawled in his ear before sucking a mark into the side of his throat, one that Robotnik knew would be visible unless he wore a turtleneck.

Robotnik was already feeling breathless and faint when he looked down to see Stone calmly wipe his ejaculate-covered palm on the doctor’s pants as well as the hem of his black shirt. Inevitably, it reminded Robotnik of all the times he had grabbed Stone by his mouth and then wiped his hand on the agent’s suit just to humiliate him further. 

Once he was done, Stone finally released the doctor and stepped back, letting the taller man sink to his knees without his support. Robotnik panted softly on the floor, his breath catching in his throat when Stone’s fingers yanked at his hair again, pulling his head back. 

“My helmet?”

Robotnik swallowed and momentarily fumbled for the words before managing to speak. “Other side of the lab. On the ground,” he murmured.

“Thank you, Ivo, dear.” Robotnik could hear the smirk in Stone’s voice as the agent let go of him. 

“See you on Monday, sir. Unless another urgent need comes up, of course.”
