Chapter Text

Aban Stone had a very stressful job, with a very stressful boss who he was very much not in love with. No matter what his traitorous heart said to the contrary.

Thankfully, he also had a good enough way of relieving his stress. He had Saturdays and Sundays off, and he made the most of it. Every evening, after eating dinner, he ran through the motions to ensure he would be fit for work come Monday. He changed his clothes, put on some makeup, tousled his normally perfectly neat hair, zipped up the boots he saved for this particular occasion, and walked the short distance from his apartment to the local club.

There, he was free to dance and drink the stress away, and maybe take some random guy home with him and pretend for a night that it was his boss pounding into him. Sure, the shame he felt afterwards was painful and all consuming… But it was better than nothing.

That Friday was no different than any other. He allowed himself to fade into the music and the noise on the floor, laughing as his hips were grabbed from behind. He looked back with a calculating gaze. The guy wasn't bad looking — Not the type he'd take home, but sure, he'd dance with him.

So there amongst a sea of random, faceless people, he let the stress of the week melt away as he lost himself in the pulsing music and lights. This was exactly what he needed, and by the time he made his way to the bar to get a drink he was flushed and panting softly. The bartender made his drink without him needing to ask; he came here often enough that the man behind the counter might as well have been an old friend. He knew what he wanted.

Stone thanked him as he handed over his card for his tab, sipping his drink and sitting down to rest for a bit. He watched the throng of people on the dance floor, humming contentedly as he finished his drink. He almost didn't look up when the club doors opened, but when he did, Stone choked on his drink and quickly turned away, hiding his face with a hand.

"You good, Aban?" The bartender asked.

"That guy who just walked in is my fucking boss."

"Oh, shit."

Fuck, fuck fuck fuck what was Robotnik doing here? He never came here, or anywhere for that matter! He'd said himself that clubs were cesspools of humanity's lowest denominators! Stone groaned, tipping his head back and half hoping he would just sink through the floor right then and there. He was dead. Sure, maybe he couldn't really be fired for what he did off the clock, but oh the doctor would make his work life hell if he was spotted here.

Safety in numbers, he decided. He hardly had any better options. He tossed back the rest of his drink and, still hiding his face, slipped back into the masses. It was unlikely he'd be spotted here, among a packed crowd of people where the Doctor would have to brush shoulders with strangers just to have a change of finding him.

"Hey there gorgeous," a voice said right against his ear, an arm catching the side of his hip to halt his movements. "You hiding from an ex?"

Stone snapped his head up at the intrusion, coming face to face with a stranger that was... Hm. Almost passing enough to forget for a moment. He was no Robotnik, clearly far too dull minded and lacking the sharp, intense look in his eyes. But he had a similar enough haircut and facial hair, and was only a bit shorter that the doctor was. 

"Worse," he answered, "My boss."

"Oooh, tough break."

There was no interest in what Stone was actually saying in that voice, but there was certainly interest in the way he looked. Stone moved closer. 

It would be easy to pretend.

Chapter Text

Ivo Robotnik was certain in his knowledge about just about everything — Scratch that, he undoubtedly knew everything there was to know about everything there was to know it about.

He believed, quite firmly, that this rule went doubly for Stone. His assistant was as dutiful as his machines, utterly incapable of surprising or catching him off guard, and that was the one and only reason that he even bothered to keep him around. No matter what any late-night sense of sentimentality might suggest, it was the convenience, and nothing more.

Similarly, it was only the lack of that familiar and reliable convenience that made the weekends particularly loathsome. Nothing more. Watching Stone leave with a finality and — perhaps an eagerness?! — That he didn't have to see throughout the work week didn't bother him in the slightest, of course; although he did briefly consider setting the liquor store on his route home ablaze when he found it closed one hour earlier then the posted times.

Cursing everyone and everything around him into an early grave, he shrugged himself into simple, dark clothing not much unlike what he wore around the lab, and dragged himself down to the depths of the masses if only to have a damn drink.

Robotnik regretted his entry into the somehow-still-licensed den of lechers just as soon as he'd forced it on himself. His every heavy-footed step towards the bar was punctuated by a silent promise to himself that if he simply managed not to kill anyone — which wouldn't even be too terribly difficult, so long as no one touched him — He could get himself just inebriated enough to sleep without thinking himself into a veritable frenzy.

He didn't bother taking an unceremonious seat, instead electing to lean over the bar to the point of discomfort as he snapped out an order for 'something plain, smooth, expensive, no ice, no nothing other than what comes out of the damn bottle'. All the while trying to avoid the gazes of anyone who might deem it worth losing an eye just to look at him.

His sour mood was entirely Stone's fault — He'd just seemed so fucking eager to leave earlier — And he was already running through how he was going to make Monday's return to work a living hell. Vaguely, he thought he could feel the by now all too familiar presence of his assistant, which was entirely ridiculous and all the more reason to punish Stone come Monday. Still, it had him lifting his head and casting a scrutinizing gaze across the bar.

The noises of stupidity and carelessness radiating from the dance floor made it effortlessly the last place Robotnik wanted to be. He stayed close to the bar, snipping harsh words at the moronic bartender — Seriously, how fucking hard was it to open a bottle and empty its contents into a class? — And cradling his drinks like his life depended on it. The longer he stayed in this place, the more it was feeling like his life did depend on it.

Out of the corner of his eye he caught a pair of particularly moronic drunken morons making out too close for comfort, moaning and spit and all other manner of ick swapping between them. It was more than enough to have the Doctor shoving himself to his feet and marching around to the other side of the bar, where he promptly emptied a stack of dirty dishes straight into the floor and snatched an entire bottle in the brief ensuing chaos. Put it on my fucking tab.

It was anger and little else — save for the bottle, his new best friend — That accompanied him as he moved to finally leave. But then again, some of his very best ideas had come to him whilst drunk and angry, so he decided to indulge in one more good hard look around the place.

Ah, yes, perfectly vile. He had just about made it back towards the exit when he could no longer ignore that strange feeling of familiarity crawling up his neck, and he found himself instead moving further into the den of lechers, searching for something he knew damn well he would not find because Stone knew better.

Robotnik allowed himself to stare into the depths of the lowest this planet had to offer for just long enough to satiate that strange urge that had risen in him. Oh he could just see the look on Stone's face Monday morning when he walked through the door and was promptly slammed against the nearest surface. He would never know that he was being punished for his boss thinking about him a little too much in his off time, but Robotnik knew, and that would just have to be good enough.

He had finally, finally deemed himself thoroughly tormented enough to get the hell out of dodge when his eye was caught again all too suddenly for his liking. Leather and mesh, dark eyes brought out only more strikingly with intentional strokes of eyeliner, a broad frame somehow made all the more intimidating in a heeled pair of boots — A stranger, in this place of all places, so by all accounts an object of his disgust if there ever was one.

So his brain veritably short circuited when every drop of blood in his body rushed to his cock with such suddenness that his vision blurred and he swayed on his goddamn feet. 

A now-trembling hand lifted steadyingly to his temple as he tried to figure out what the hell had just happened. It wasn't just that it had happened, that it was still happening, but the why of it that had his mind spinning in a way it usually didn't have to spin.

He took a heavy step closer to the stranger, shielding himself far too close to other bodies for his liking as he raked in the sight of —

Stone.

Yes, in spite of his certainty that Stone knew better, there he was — Dressed in a mesh crop top, tight leather pants, and leather boots with heels that could probably be used to proverbially kill a man. He was wearing makeup, dark eyeliner around his eyes and glitter that started on his eyelids and smudged down across his flush face. His hair was artfully mussed instead of the normally carefully, neat style he usually kept it in, and he looked... Happy. Dreadfully, blissfully content. 

And far, far worse than all of that — He was chatting idly with the man who'd approached him, almost seeming to… Flirt. Not that Ivo Robotnik was familiar with such a loathsome activity, but... There his assistant was. Dragging a hand over his chest, laughing at what was no doubt an absolutely terrible joke and leaning close, thoroughly distracted from his boss's presence in the club.

Stone. He couldn't even revel in his flawless instincts being proven correct, because there was Stone, his Stone, in this place, looking like that — And touching some imbecile like his life fucking depended on it.

Robotnik could only watch. And as he did, a raw ache ran through him, unfamiliar and painful.

Chapter Text

Robotnik didn't need to worry about whether he could get close enough to hear without making himself seen. He simply let his technology do the work for him.

"God, you're really somethin' to look at," the drunken plebeian was cooing at his sycophant, reaching out to sidle a hand up his thigh.

"Mmm, you're not so bad yourself," Stone hummed, "You come to this place often? I don't think I've ever seen you here before."

As he spoke he trailed a hand up the man's chest, leaning into the touch on his thigh and smiling coyly. The entire display made said stranger lean forward in the same moment that it made Robotnik want to be sick.

He could only watch, and now only listen, as the man slid his hand up even further and drawled out, "I would've started here a lot sooner if I'd known you would be waiting for me."

Ah, yes, so this man had watched entirely too many shitty romance movies in his lifetime. Fucking figures.

But Stone looped an arm around the man's neck and laughed. Actually laughed, as if that was either funny or charming. "What do you say we get out of here then, hm, handsome? My place isn't too far from here, within walking distance. I just need to close out my tab at the bar."

Flatterer. Stupid, ridiculous, moronic flatterer wasting his goddamn breath.

Handsome? He most decidedly was not. Get out of here? Disgusting. My place —?!

Robotnik's mind was reeling. Stone, his Stone, was here in a nightclub about to bring a complete stranger — and a particularly inferior one at that — Back to his own home, which Robotnik himself had never seen.

Good a time as any to fix that, he decided, already knowing damn well that he would be surveilling them at the very least. He got a head start as Stone closed out his tab, the smallest drone in his possession left behind to feed him intel in real time as the asshole followed Stone eagerly back towards his place. Both men remained unaware of the surveillance, and it was very nearly disappointing — Really, Stone? Possessing the same understanding of his own surroundings as some common, drunken nobody?

Robotnik called a car back towards the lab with a wave of his hand, watching the feed every step of the way and biting at every word through his headpiece with a bitter fixation.

Stone stayed unaware long after he’d unlocked his front door, letting both the stranger and the drone inside before it closed again. Robotnik told himself it was the inebriation, if only so he’d want to kill him ever so slightly less for not noticing as he watched the feed.

"Okay, handsome,” Stone was purring in that ridiculous, moron-coddling tone he had apparently perfected through the years. “I've got a few rules. If any of them are deal breakers you can leave. I'll call you a cab and give you some cash, and you can go back to the club and find a new partner with no hard feelings, okay?"

It might have been admirable that Stone was being so considerate to a stranger if it weren't so damn annoying. Robotnik was pretty certain he should have ground his teeth into dust by the time he made it to the center console of the lab, eyes never once leaving the screen. He stashed the stolen bottle into his jacket pocket and forgot about it immediately — Not that it really mattered; he’d downed most of what remained in the backseat on the drive.

"Mhm, whatever you need," the man was throwing absently over his shoulder, already discarding his coat into the floor as he moved closer to the bed. "What are the rules?”

"First, a pretty simple one — You have to wear a condom," Stone said. "I'm trans, and way too busy for a baby."

“What’s the next rule?” and god this imbecile didn't even try to sound like he was actually interested.

“I want to call you 'doctor' while we're fucking. Call it a kink if you want. And the third rule — I don't want you to be gentle. But don't leave any marks that can't be hidden by a collared dress shirt. I don't need my employers asking questions, so anything below the neck is fair game."

Robotnik stayed standing at his work desk, tense and trembling with rage and absolutely nothing else. Just what the hell did Stone think he was doing? He was —

Doctor. His blood ran cold in the same moment that his face flushed, because that was his title, their name, for only him and only Stone and now — He was about to call another man Doctor?

The pathetic excuse for a meat suit lifted a brow towards Stone, but didn't object. "I think I can manage that," he said around a half-amused laugh. "Doctor, hm? Where did that one come from?"

Even as he asked he hardly seemed to care, already moving towards Stone and shrugging unceremoniously and impatiently out of his pants

Stone just smiled. "I'm allowed to keep some secrets," he practically cooed, hooking a finger into the man's collar and leading him back towards his bedroom with a smirk.

The bottom-feeder followed his assistant and so did the drone Robotnik had sent after them. He paced the floors of his lab, watching as the rage grew and grew still.

Stone wasn't his at all, it would seem. He simply liked the title and the power it that being beneath him offered. And now he was eagerly shelling that out to the first taker.

"Keep them, then," the man was saying with an absent grin, closing the gap from the moment they were in Stone's bedroom.

Robotnik stopped pacing when Stone rocked up on the tips of his toes to pull the stranger into a kiss, hungry and desperate and human and all the things his assistant decidedly was not.

And yet, there Stone was. Willingly kissing some nobody in his goddamn home, humming against his lips and looping his arms around his neck. He pulled the nameless sack of flesh down onto the bed, laying back and pulling him down over him without breaking the kiss.

Heat and disgust alike sparked in Robotnik as he watched him hook a leg over the man's hip to pull him tighter against him. It didn't cross his mind to feel guilty for spying on his assistant like this — Stone belonged to him, after all, even if he seemed to have entirely forgotten about that fact.

All he could focus on was the anger and disgust. Anger — That his sycophant was about to do something so unbelievably stupid and debasing. Disgust — That his own body was betraying him so eagerly as he watched. The heat... No. That was all in his head.

The nobody from the bar fished his cock out of his pants and lazily stroked himself. He was already snatching a condom, seeming all too in a hurry, and the anger flared even deeper. Did Stone truly believe that was good enough?

He paced closer to the door of the lab, suddenly not having the slightest clue why he'd come back here at all when he should be beating Stone's front door off it's hinges. Stone, who was —

Stripping his clothes and throwing them to the side of the bed. Kicking his boots off and letting them clatter to the floor. Spreading his fucking legs for this imbecile —

"C'mon, doctor, I'm all yours," he purred.

Robotnik froze by his front door, trembling with a humiliating fervor as he watched as he fought a wave of pleasure so agonizing he feared he'd cum on the spot.

He couldn't go to Stone's apartment. Stone would know he'd been watching, and then he would run off getting ideas in his head that Robotnik actually cared what the hell he did in his off time. Besides, what exactly was he going to do? Scream at him for daring to fuck a stranger when Robotnik didn't even want him like that —

And he didn't. He didn't want him like that. No matter how desperately his body tried to react when he ignored the stranger and focused on Stone, perfection with his legs spread and waiting for a mediocre fuck.

"Fuck me, hard and rough. Don't you dare be gentle with me," Stone panted, actually panted in anticipation, and Robotnik dug a gloved hand into the wall so hard he could feel his knuckles going white.

"You want it rough?" the Stand-In preened, and Robotnik actually rolled his eyes, because come on. But then he was slapping his hands down across Stone's thighs and holding them down against the bed as he lined himself up.

"As rough as you can be," Stone echoed, grinning up at the man as if he actually had anything to offer.

Robotnik walked at a normal pace and most certainly did not veritably dive for his work desk, hands clawing out in search of his phone. If he was going to have a shit night, then so was Stone. The feed from the drone was playing out of the screen on his control gloves, but he couldn't find his fucking phone —

He heard the stranger wrench Stone's legs harder against the bed with a half-assed attempt at bruising strength before he saw it. It was against his better judgement that he looked down again, just in time to catch the Nobody rake a swipe of fingernails straight down Stone's chest in the same moment that he shoved his cock forward. 

Robotnik felt hot shame — shame, him of all fucking people feeling shame — as he paused his search all over again just to watch the nobody unceremoniously shove himself inside of Stone.

Stone gasped at the pathetic red marks on his chest as he pushed in. He groaned when the man bottomed out inside of him, head falling back against the bed as an inferior body immediately slammed against his again and again.

Besides the harsh thrust of his hips, he couldn't even follow a simple order right and make it fucking hurt.

The only thing worse than the fact that he was watching this at all was the fact that Robotnik was painfully, agonizingly hard. He was still trying and failing not to catch how good Stone looked as he was fucked, even so pathetic a fuck as this was —

His body froze all at once when Stone snapped a hand out, grabbing the back of the man's neck and squeezing hard enough that his knuckles went white.

"You can be, ngh, rougher than that, can't you Doctor? I wanna, h~ah, really feel it," he practically growled.

Hearing Stone speak like that had Robotnik's knees threatening to give out. There was something in his voice that made him finally realize all at once what this really was.

It wasn't about the title, nor the power behind it. It wasn't about sycophantic groveling, nor grasping for some sick sense of control.

It was about him.

Stone wanted to fuck him. Stone was fucking strangers in his bed imagining that it was him. Stone, his Stone, wasting his time looking like that for assholes like this —

"Whatever you say," the Replacement Wannabe grunted, his hip bones slamming against Stone hard and clumsy. He brought a hand down across Stone's thigh, and Robotnik could feel the weakness in the slap through the screen.

"Oh, fuck," Stone whined, the hand not gripping the back of the man's neck moving over his bicep as his eyes fluttered shut. "F— Fuck..."

And that was fucking it, because oh fuck no, he was not moaning for this asshole —

The hard but lazy thrusting continued sickeningly through the screen on his wrist as Robotnik finally threw himself into the task ahead and found his damn phone, discarded amongst an array of half-finished blueprints. Immediately his fingers were flying over the screen, dialing Stone's number and —

"Ah, shit, I'm getting close —"

Hitting send on the call.

"Show me who's more important," he hissed into the feed.

Stone still couldn't hear him, of course. But if he knew what was good for him, he was fucking about to.

Chapter Text

A thrum of white hot satisfaction had run straight through Robotnik's entire body when Stone all but shoved the stranger off of him to answer his beckon. He’d still had to fight to keep his own voice level with the mounting rage clawing at him when he demanded Stone return to the lab, but — 

But through his rage, something was soothing. Stone, his Stone, was still fucking his after all. He had palmed at the hard line in his pants, trying to calm himself down and leave well enough alone before —

Not enough, not enough, not enough. The tension in his body was threatening to unravel him, nerves and excitement and, yes, still anger rolling through him in droves as he waited. The only other thing that found its way into the mix was disappointment and newly-ripening rage that Stone had made him wait even longer just so he could change his clothes.

But Stone had come back all the same. And Robotnik had given himself one, two, three beats to drink in the sight. 

If it weren't for the vague smudges of glitter and charcoal around his eyes, so easily missed if it were anyone else, he would never even known. Stone had walked into his lab the very same picture-perfect vision of ease and service that he always was.

He gave himself ample time — or maybe it was just all of two seconds — to change his mind before he was slamming him into the wall. But Stone still managed to look just all too fucking perfect, and he hated him for it. He hated him, he hated him, and oh god he needed him.

Now that the dam had been broken — not that he required any such thing to make him want to lose his mind at the sight of Stone looking up at him like that — Robotnik couldn't get enough of the bruising contact.

It was that viciously unfamiliar feeling of having his self control bit and clawed at that made him keep his hands to himself for the entirety of the car ride. He was not going to give Stone the satisfaction of seeming him so weak, so burdened by arousal that he felt the need to dig in with tongue and teeth and hands. It was bad enough, really, that he had let the bastard convince him to get into the damn car in the first place. 

"If you come back to my place… I can show you something better than what I was wearing at the club."

Robotnik was still so painfully aroused, and through it all he still clung to white hot rage.  The unceasing mental images of Stone sprawled on his bed for an absolute plebeian were more than enough to make his blood boil as he slid against the far window of the car and dug his hands into his own thighs.

And through it all Stone was still smiling. Determined to break that damn grin was all the Doctor could be as he glared at him in the low light. He could all but feel his own eyes flashing with lust and with the need to know, and he silently cursed his body for betraying him so readily. Outwardly, the punishment would belong only to Stone. He would make damn sure of that. His hands tightened sharper around his thighs at the thought, but patience was still his to hold until the very moment they were inside the apartment. 

He kept his back firmly against the front door, leg bouncing impatiently as Stone quickly disappeared into his bedroom. He could hear him shuffling through his things, audibly more hurried and clumsy than he would usually dream of being in front of his boss. When he finally stepped out again, he was taking a deep breath and lingering in the doorway with wringing hands. 

He had promised to show the Doctor something better than his outfit at the club, something he definitely couldn't get away with wearing in public — And oh how he had delivered. 

Robotnik felt his breath hitch sharply when Stone re-entered his line of sight, drinking him in with clouded over eyes. The bastard stepped out wearing a black lace one-piece that cascaded over his broad chest only to split wide open between his legs. The boots he wore were even higher than the previous pair, trailing up his toned thighs as he leaned a hip against the frame of his bedroom door.  

The Doctor took in the sight with an eagerness that was damn near humiliating, the rolling wave of arousal and want that washed over him so intense that it was painful. He was closing the gap immediately, every step wide and betraying the hunger he felt. He didn't stop moving until he had Stone crowded against the wall next to the bed. 

"God you're such a fucking deviant," he seethed, brushing his gloved hands across the lace over Stone's chest.

Stone simply smiled up at him, readily allowing himself to be shoved against the nearest surface and practically purring as those hands descended on him. He parted his lips to moan softly against the pressure on his chest, back arching into the touch as he breathed out, "I take it you like it…? Please, Doctor, I’ll do anything. I want you so bad it hurts."

Robotnik's eyes flicked up, brows narrowing sharply at the question and the pitiful ensuing plea. He bowed his head to scrape his teeth delicately across the lace, before abruptly biting down on his nipple damn near hard enough to break the skin. His hands explored Stone's body greedily, dragging and digging his nails through the surface of the gloves as he went. The arousal was overwhelming, all consuming — And sharply followed by another punch of anger. 

He eased in closer, pressing his still-clothed erection against Stone's now exposed thigh as he finally pulled his teeth away to speak. “You’re lucky tonight's fuck was a weak one,” he seethed. “If I'd been forced to watch someone else make you beg —“

The thought alone had him snapping his hand up and latching it tightly around Stone’s throat. He heard the gasp more than he felt it, the younger man choking out a strangled moan as Robotnik's grip tightened. He could see the darkness dancing at the edges of Stone’s vision, but through it all his eyes were dark with desire as he mindlessly bucked his hips up.  

“I — I would never —“ Stone bit out weakly, but Robotnik didn't let up.

He held his hand there, tighter and tighter, for one beat longer than he should have. It was such a beautiful sight, this pitiful man holding bone still even as the life was damn near choked out of him. Feeling a wave of satisfaction at the thought, Robotnik released his grip all at once. He watched his assistant pull in a deep breath, filling his lungs with air desperately and still looking every bit as eager as he had before there was a ring of hand prints wrapped around his throat.

Good. Robotnik was nowhere near finished with him. 

The contact had only been broken for truly no time at all when Stone bucked his hips up again, a noise that could only possibly be called a whine leaving his parted lips. 

"What is it?" the Doctor preened. "Don't tell me you're desperate already. Don't tell me —"

There was no warning as he dragged his hand in between Stone's legs. He was absolutely drenched, thighs already slick with his arousal, and he cried out obscenely as Robotnik ghosted his fingers over him with a feather-light touch. 

He was desperate enough to try and rut his hips against Robotnik’s hand, and seeing as how he had not been given permission to do any of that, Robotnik ripped his hand away and slammed it across the side of Stone's thigh. The impact of it was newly slick and more than hard enough to welt, imprints immediately beginning to bloom across the surface of his skin. 

"Disgusting." The word leaned more towards a purr than a growl. "You're dripping all over me."

It was all the warning Stone would get before he abruptly shoved two of his now-slick fingers into Stone's mouth, hooking around his bottom teeth. He pulled him forward just as he slid his still-clothed knee between his legs, digging in sharply as his free hand resumed its exploration lace-covered skin. 

Stone’s hips were twitching beneath the contact, overstimulated body trembling against the urge to stay obedient, and for a good hard moment Robotnik simply watched. He watched Stone whimper and swallow thickly, tasting himself on his boss’s gloved fingers, he watched him shake against the contact between his legs — 

And then he let go all at once, taking a heavy step back and snapping, "Go get on the damn bed."

Stone, poor, pitiful Stone, damn near collapsed to the floor without the Doctor to brace him against the wall. But he still hurried to the bed, following orders even on shaking legs and laying down on his back with a few soft little pants. He watched and waited, eyes hooded and clouded over — 

But Robotnik was in no hurry for perhaps the first time in his entire life. He lingered by the wall, taking in the sight with hunger no doubt every bit as apparent in his eyes as it felt in his chest. When he finally did move, it was evenly towards the bed, strides slow and steady as he shed the draping, knee-length fabric of his coat. He discarded it to the floor and his shirt right along with it as he finally reached the bed, sinking one knee into the mattress.

His head tilted to the side, watching Stone with a half-smirk pulling at one corner of his mouth. He remained unmoving for just one moment before he lunged, laughing low in his throat as he threw himself over top of his assistant and raked his gloved hands down over both of Stone's nipples. He continued the punishing motion all the way down to his hips before his hands finally found a digging purchase against his thighs, wrenching them open none too gently and slotting himself in between them. 

Every minuscule little thing he did tore new and more interesting sounds out of the man writhing beneath him, head slamming back as he gasped and groaned. He didn't fight as his thighs were wrenched open, crying out and bucking his hips desperately.

When he lowered himself back down it was purely to follow the drive to punish the man beneath him more and more. The sight of Stone panting up at him like that most certainly did not make his body go so weak that sitting up became damn near impossible. 

"’No marks my employer can see,’" he echoed against the shell of his ear, biting down on his earlobe and drawing out a beautiful little shudder. "I think your employer wants to see you marked to pieces like the aching little thing you really are."

 "Y-yes, please..." Stone wheezed out, shaking with an anticipation that was visible through every cord of his body. 

And in spite of himself, a pleased growl rumbled in Robotnik’s throat. "Please," he mused. "That's more like it."

With that he bowed his head and bit down sharply just over the center of Stone’s neck. He set his jaw and pulled harshly, knowing full well there would be a nasty purple welt by the time he was done. Stone gasped and moaned beneath him as he sucked and bit a dark mark right into the flat of his throat, where it would be easily visible the next day and for days to come. 

Satisfied, Robotnik lowered his head again, this time biting Stone's collarbone. The whimper that had left him when he'd pulled away contact for that one brief moment had him giving an amused lift of his brow, and the following moan that punctuated his next bit had him grinning against flesh. 

He kept working his way further and further down, trailing a path from throat to collar to chest and stomach. He worked his way around and through the lace, refusing to see the piece discarded after how hard he’d worked to see it on him. Peppered bruises and bites were left all the way down, rocking up on his knees to latch onto a place higher than the last just so he could feel the ripple of shock run through Stone’s body. 

His hands traveled down, roughly wrenching Stone's even further thighs apart just so he could — 

Hm. Robotnik paused all at once, unlatching his teeth and pulling away from Stone, ignoring the keen the poor thing let out at the loss of contact. He lifted his hands and examined them for one moment before he sighed, sliding his control gloves off one finger at a time before finally discarding them onto the bedside table.

Stone watched the entire display with wide eyes, swallowing thickly and choking out a really rather pathetic, “Oh… Oh god…”

Robotnik rolled his eyes as his now-bare hands returned to Stone's legs, pushing his weight up against his thighs as his fingernails dug in against flesh for the very first time. He scratched a few experimental trails along his thighs and all the way up his chest as he grinned, more than confident that they would actually stick around — Unlike the previous moron's half-assed attempts. But if only for good measure, he shifted his weight back to his knees and scratched down Stone's chest again, a flash of teeth in his grin as the places darkened and reddened even more.

Robotnik pushed himself up on his hands against Stone's thighs, eyes narrowing as he trailed the path his nails had made. He smirked down at the sight, more than confident that they would actually stick around, unlike the previous moron's half-assed attempt. But if only for good measure, he shifted his weight back to his knees and scratched down the entire expanse of Stone's chest one more time, a flash of teeth in his grin as the places darkened and reddened even more.

When he lowered himself down this time it was to set to work in between his thighs, teeth and tongue and closed mouth latching against tender skin. He bit and prodded until a heavy ring of bruising was visible, and then he promptly moved onto the next place. He pointedly avoided any contact between his legs, although more than once he moved close enough to wet his lips as he left another love bite at the very top of his inner thigh. Every mark he left was vicious and no doubt painful, but also agonizingly slow and unpredictable in their progressions. All the while, Stone writhed and moaned and panted eagerly beneath him. 

He didn't pull back again until Stone's thighs, hips, throat, chest and stomach were covered, damn near every part of him peppered with bruises and teeth marks. He was already hungrily eyeing the one on his throat again, considering the many, many options that were quite literally splayed out before him.

"It's not too late, Stone," he mused. "I can take you back to the club. Help you find some poor imbecile for you to call by my title just so you can take care of yourself after they get off and leave. Does that sound about right? That's how you've been passing your time for… Oh, what was it. A few months, you said?"

"N-no!" Stone gasped out quickly. "No, I only want you, Doctor, please. No one else is worth it, they were all poor substitutes — I've been so patient. I’ve wanted you all this time, please, please..." 

He was still trembling, panting heavily and arching his back. He canted his hips up again, visibly every bit desperate for some attention between his legs as he begged and begged some more, and goddammit it all to hell if that sound didn't make the Doctor’s cock ache more than it ever had in his entire life. 

"That's better, Stone," he bit out. 

He watched his assistant arch and writhe beneath him for another moment before loosing a long suffering sigh — And promptly pumping one finger in between his legs in the same moment that he latched another bruise into the bone of his hip.

"Oh god, fuck, d-doctor please!" Stone cried out, moaning loudly and slamming his head back harder against the bed. 

"All that over one little finger?" His grin only widened as he worked in a second, working him open with a bruising hit of every other knuckle as Stone rocked his hips mindlessly against the contact and whined. 

He abandoned the vicious bites for long enough to bring one hand instead to Stone's throat, applying an intensely calculated pressure on either side as he fucked him against his hand. 

"You don't deserve this," he said matter-of-factly, still pumping into him at a cruel pace. Stone whined, damn near drooling as his eyes fought to focus on the Doctor. 

“I k-know," Stone panted, eyes lolling back ever so slightly. "B-but, h~ah, th-thank you..."

"And thanking me for it, too. Oh, Stone, I don't think there's anything you wouldn't let me do to you right now. God, just look at you... Still so damn desperate..." 

The purr was punctuated by him abruptly withdrawing his fingers. He put one in between his own lips, sucking it clean before shoving the other one into Stone's mouth and watching him do the same with a pitiful little moan. 

Looking every little bit thoroughly pleased with himself, Robotnik sat up on his knees and slowly undid the button of his pants, sliding the zipper down and finally freeing his painfully-hard cock. Leaving it neglected for this long simply had to count as some sort of torture, but he was nothing if not an expert at ignoring the needs of his own body. At least, until tonight he had been. 

But the feeling had grown to be unbearable against his clothes, and he stroked himself in his hand before abandoning the venture completely in favor of fully undressing himself and discarding his meager remaining clothes onto the floor. 

Stone’s eyes sharpened with a sudden clarity, trailing down and letting a whine escape him at the sight of his boss’s cock. “Sir, you’re perfect,” he bit out, damn near drooling.

Robotnik rolled his eyes with a grin as he straddled Stone just over his hips, grinding his erection briefly against the man's thighs at the expected praise. He found himself admiring the scraps of crafted lace against his assistant again, fingertips digging into the bite of the fabric.

"I should make you wear this every day," he breathed, shifting enough to wrap his still-wet hand around Stone's jaw. 

"I'd do it," was all the younger man got out before their mouths were slotted together in a tangle of tongue and teeth, Stone rocking his hips and feverishly digging his hands into whatever he could reach. 

Robotnik slid his tongue eagerly into Stone's waiting mouth as he kissed him, still tasting his assistant's arousal between their mouths. When he finally broke the kiss he clamped his teeth down sharply against Stone's bottom lip as he rocked back on his hips again, eyeing the younger man up and down as he stroked his cock slowly and considerately.

"Tell me what you want, Stone," he breathed out. "If only so I can have the pleasure of saying no."

In truth, he was torn. He wanted to keep marking and bruising and welting his sycophant until he couldn't walk. He wanted to fuck him so badly he himself could barely think straight. He wanted to bury his mouth between those perfect legs and make him cum so hard he saw stars.

Stone moaned as Robotnik bit his lower lip, trembling and swallowing thickly as he broke the contact again. His hips were twitching as the other rocked down against him, another cry escaping him. He was so damn eager, so damn responsive, and so it really shouldn't have been surprising how eager he latched on to the command he’d been given.

"Fuck me. Please, please, please just fuck me, I need it so bad, I need you inside me, please Doctor I need you..." he begged in one long, unbroken stream of desperation, canting his hips obscenely in search of any minuscule amount of contact. "Please, please I'll do anything..."

Robotnik sighed sharply through his teeth at the display. He lowered himself to drag his cock slowly between Stone's legs, drenching his length immediately before moving away again. He should have gotten up and left him alone in the bed right then and there, but… 

He would sooner die than admit it out loud. But the sound of Stone — his Stone, the perfectly composed, well trained government lapdog that he was, who never once lost his composure... 

Seeing him beg like this was very nearly too irresistible for comfort. 

"Hmm..." he considered. "Perhaps I could be convinced, after all..."

Maybe he could withstand and then even surpass the blow this already threatened to bring to his pride — So long as he made it hurt badly enough. 

He moved back down to nestle himself between Stone's legs, digging his hands into those perfect thighs again until he could've sworn he could feel bruises beginning to form beneath his fingertips. He motioned vaguely toward Stone's nightstand, where he assumed he kept condoms. He still remembered the rules, after all; he was just undoubtedly going to outdo every single other man who had ever heard them before him. 

Stone groped blindly for the drawer, wrenching it out and tearing a condom out and open in one violently fluid motion. He panted softly, every bit alight with anticipation, cheeks flushed and hair once again mussed from all his writhing. The eyeliner he had reapplied was beautifully smudged in the corners as he moved to sit up, silently offering to put the condom in his hands on the doctor himself.

There was an amused gleam in Robotnik's eyes as he watched him. 

"If you're that desperate to get your hands on my cock, just say so," he mused, running his fingers through Stone's hair only to dig in and wrench his head just slightly to the side. "Just ask to touch me."

Stone moaned somehow louder as his hair was pulled, immediately and predictably giving in to the demand. 

"Please, please let me touch your cock..." he pleaded, looking up at the doctor with hooded, lust-darkened eyes and practically nuzzling the hand pulling at his hair. When that didn't immediately work he whined again for good measure, arching and rocking against the minuscule contact between their legs. "Please, please..."

Stone was immensely lucky that he looked so goddamn good like this it was criminally impossible to say no. The grip tangled in Stone's hair tightened sharply, pulling him harshly forward until their mouths nearly met. “Go on,” he growled out, releasing him all at once — Permission granted.

Stone hurried to obey, moving to slide the condom onto the doctor — But not before wrapping a hand around him and stroking, flicking his thumb over the head.

"Fuck... you're so perfect..." he breathed in awe, squeezing around his cock as he stroked him firmly.

Robotnik had to swallow a choked groan as Stone's hand enveloped him. He hissed through his teeth, bucking once into the touch before he immediately pulled away. He was not about to reward him with something as ridiculous as moaning. 

He was pointedly silent as he lined himself up between Stone's legs, rolling his hips forward but not yet pushing in. Stone immediately relaxed, obediently laying back down and shivering as his cock ground against his slick entrance. 

"When I saw you in that nightclub,” he bit out, “I wanted to bend you over the counter and fuck you right there in front of everyone. I've been waiting ever fucking since —"

And desperately, painfully hard for damn near every step of the way.

Stone whined at his words. "You, h~ah, sh-should have. I w-would've, ngh, let you,” he admitted breathlessly. 

And God if that thought didn't go straight between his legs. The idea of bending Stone over in some sleazy bar and roughly pounding into him, claiming him in front of everyone there — 

Robotnik laughed low in his throat, hand still firmly pressed against Stone's chest to keep him lying against the bed. 

"Oh, please, Stone," he huffed. "I'm going to fucking own you after tonight, even more than I already do. I'll fuck you wherever I damn well please, in front of whoever I damn well please. You're already going into work on Monday with my teeth stamped all over you."

To make his point, he lowered his head pointedly to the side of Stone's throat and bit down again. There was no mercy in the bite, and even less in the way he rolled his hips forward sharply — And buried himself to the hilt in one harsh thrust.

Immediately Stone was crying out for him. "O-oh, God!" he gasped, trembling and arching and whimpering somehow far more than he already had been. "F-fuck, please..." 

Robotnik bit down on his tongue as he fucked his assistant, still hardly about to reward him by moaning, even though he felt so stupidly damn good wrapped around his cock—

"You're mine," he growled, biting down into his throat once more for good measure. "I'm never letting anyone else touch you again after this."

He slammed into him harshly and without mercy, again and again and again, drawing himself almost entirely back out only to sink back in. And all the while Stone rocked against him, whining desperately. 

"I'm yours, all yours, a-always, h~ah, h-have been, I swear it…” 

Robotnik anchored both of his hands against Stone's hips, angling him upwards as he slammed his cock inside him all over again. Stone cried out at the change of angle, pleasured tears clinging to his lashes. 

"O-oh god, Doctor!" he gasped out. "Yours, yours yours yours yours~!" 

The brainless babbling continued as Stone locked his legs around Robotnik's hips, pulling every harsh thrust tighter against him and raking his nails down his back. Robotnik hissed and rocked himself forward against the pressure lighting up the skin of his back. Stone was so damn lucky that he looked so damn good like this, felt so damn good like this...

"I should bend you over the console in the lab and fuck you while I work,” he breathed, slamming harder between his thighs. “Make you crawl under my desk and suck my cock while I'm on calls..."

He groaned low in his throat, snapping his mouth closed. The thought alone was damn near enough to make him cum, but the sight of Stone writhing and keening and still babbling beneath him was all that much more unraveling.

He rolled his hips forward harshly, again and again, hands traveling across lace-clad skin and being certain to dig into the particularly nasty bruises he passed. Stone gasped and choked, visibly reveling in the pain it caused.

"Please, please, yes!" Stone cried, bruised body shaking pleasurably against the other’s bare skin. "I'll do anything, anything f-for you! P-pleasing you is, it’s all I want…" 

"You'll have a lifetime to prove it to me," Robotnik ground out, growing more and more breathless with every ruthless slam of his hips against the writhing man beneath him.

He dug his fingertips into the small of Stone's back, hands still wrapped firmly around his hips as he thrusted into him. He wanted to flip him over and fuck him with his face down in the pillows, but watching the pleasure play out on his assistant's face was just too good to pass up.

Seeking even more of it, he let go of one side of Stone's hips and rubbed his thumb just above his cock's entry. Immediately he was rewarded with a rumbling keen as he worked his hand where they were joined, meticulously touching over the sensitive nub there. It had barely been more than a moment before Stone was unraveling at the goddamn seams. 

"F-fuck, close, I’m —“ Stone slammed his head back again as he choked out the warning, a warning that immediately turned into more pleading. "Let me cum, please, please Doctor let me cum…" 

Robotnik let out a breathless, short-lived laugh as Stone so readily begged him. He slowed his pace slightly, leaning down to croon against the shell of his ear as his hand still worked between them. 

"Yes," he bit out. "I think you've learned your lesson well enough. Cum on my cock, Stone. Now."

He slammed his hips in harder and deeper as Stone cried out, arching and writhing between his boss and the mattress as he came. He was clenching around his cock tightly as he practically screamed in pleasure. 

There was no doubt that any number of his neighbors could hear him through the walls, but Robotnik couldn't have cared less. Stone had his full, undivided attention — A first. A last, too, provided he could wrestle his self control back into its rightful place after tonight. But in the meantime… 

"Oh god, oh god oh god oh god," Stone babbled. He was still clinging to the doctor with both arms and both legs, shaking under him as his orgasm washed over him in ruthless waves. 

The agonizing tightness that chased Stone as he came was more than enough to send Robotnik over the edge. His perfect assistant was clenching around his cock, and he had waited so damn long and he couldn't fucking take it anymore —

"Fuck, Stone, fuck—" he ground out. His entire body trembled humiliatingly as he thrust in and froze, emptying himself with a low cry, still firmly planted inside of Stone.

Robotnik all but entirely collapsed on top of Stone, shaking and trying to catch his stupid breath. He finally forced himself to roll over next to the other man on the bed, eyes on the ceiling and contact between their skin now a distant memory. The condom was disposed of in the trashcan by the nightstand, and when he rolled over onto his side to take care of it, he stayed there, no longer facing Stone.

It was strange, the urge to reach for him that was now settling over him in the aftershocks. 

It was one thing to fuck him. Holding him was something else entirely.

"... Thank you, doctor..."

Robotnik snorted and stayed otherwise deliberately silent. He didn’t trust the sound of his own voice anymore even if he wanted to speak. 

As soon as he felt even remotely in control of his body again, Robotnik shoved himself to his feet and began to work his way back into his clothes. He marched for the door, only to freeze and linger once he actually reached it.

With a sharp sigh, he spun on his heels and walked back towards the bed. Leaning over top of Stone, he wrapped his hand around his jaw and angled his face up, kissing him deeply.

"You look good covered in my bruises," he grumbled down at him.

In spite of the harshness in his voice, Stone was quick and eager to return the kiss. He closed his eyes and even smiled brightly as they parted, promising, "I'll display as many as I can on Monday for you, Doctor.” 

Robotnik sighed heavily at that, kicking his shoes off just as quickly as he’d put them back on and dropping back down onto the bed. He laid on his side, facing Stone but still keeping the distance that was available to him.

"Fine," he snapped, as if he were suffering a punishment that was entirely out of his control. "I am still too inebriated to drive myself —" This was largely a lie, it had been hours since he'd drank anything. " — And I do not feel like waiting for a car this late at night." Another lie, considering the car they’d taken was driven by his own technology.

As he expected, Stone was too intelligent to point any of that out. Instead he simply smiled and breathed out a soft little, “Thank you, Doctor.” He shifted to get under the covers, careful not to disturb the other as he settled in.

"Shut up," Robotnik snapped, rolling over harshly and clenching his eyes shut.

He was silent for a good long while before he threw himself back around to face Stone. Every movement was harsh and sudden and none too subtle, the bed and blankets and Stone all shifting beneath the slamming of his body.

"Are you..." Irritation was alight in his voice, and he sighed exasperatedly before pushing through. "Are you okay, Stone?"

He'd thoroughly bruised him damn near from head to toe. It seemed only in good taste to ask.

Stone blinked at the question, before smiling again. "I'm okay, Doctor,” he promised. “I’m sore, and I'll definitely be feeling this in the morning, but… I’m okay. I’m more than okay. I thoroughly enjoyed every second of it. Are you okay…? I scratched your back up pretty bad..."

Robotnik looked up at Stone, at all that eye contact and that dopey little grin around reassuring words — And promptly decided that was way too much, reaching over to turn off the lamp so he didn’t have to look at it all anymore. 

He let himself snort into the darkness at Stone’s question. "Yes, you did," he remarked. "Luckily for you I'm not an overgrown weakling, Stone. I will survive a few marks on my back just fine."

He was quiet for a while before he added, "It was quite adequate, sycophant, but I'm yet undecided. I suppose more tests and trial runs will be necessary to reach a conclusive answer." 

How odd, him of all people feeling the urge to bridge the silence. He could sense Stone wanting to reach for him, could practically feel him biting his tongue for the urge to ask. 

"Of course, Doctor,” he said softly. “I'll eagerly assist you as always. Good night, sir."

That, at least, was a satisfying promise. 

The next morning saw Robotnik easing from the bed, collecting his things, and promptly returning to the lab. He busied himself  with his usual routine, an occasional soreness the only reminder of what had happened. It would be a long two days. 

But in the back of his mind, he couldn't wait to see the bruises in his lab come Monday. 

Chapter Text

It was with a shameless self gratification that Robotnik found himself checking the camera feed of the drone he'd left behind to tail Stone. The habit had initially started purely so he could make sure Stone didn't go back to that club. 

The Doctor was all too prepared to follow him if he tried it — He'd meant what he said, after all. 

Stone belonged to him. Even if the Doctor existed far outside the realm of normal human beings, even if he didn't require companionship or emotional attachment or any of that other drivel...

Stone still belonged to him.

It was an odd mix of relief and disappointment that found Robotnik when Stone set about a perfectly normal routine, although he had no way of knowing if his sycophant always looked so troubled as he set about his day.

A sick part of him wanted Stone to give him a reason to hurt again. To give him a reason to hurt him again.

The rest of him was strangely content, eagerly awaiting his Monday morning return to the lab and — 

Fuck, he was already letting this impact his work, but…

But his agent was intoxicating to watch. 

"Good boy, Stone," Robotnik muttered into the one-way feed more than once, when more and more time had passed and still Stone didn't return to the nightclub.

Although, begrudgingly, he could almost admit that he might have liked to see what his assistant would have worn.

But Stone diligently went about what must have been his usual routine, leaving the apartment only to get groceries and go for a run in the evenings — Wearing a delightfully tight pair of running shorts both times. 

The Doctor’s thoughts were of a a similar vein all day and all night, and then all damn weekend. It was pathetic. It was disgusting. It was… Incredibly entertaining. 

Robotnik tried to be relieved that Stone had never tried to return to the night scene, because really, what was he going to do if he did? The only answers that even remotely came to his mind were all illegal at best, and he really didn’t have the time to spare to go getting himself arrested.

Still, in spite of the amusement, Robotnik found himself… Disquieted.

The attraction wasn't going away. If anything, it only seemed to get worse. And as if that wasn’t bad enough, Stone managed to make him painfully hard throughout his endeavors in this new past time more than once by simply existing.

————————

Stone couldn't even begin to stop thinking about it. 

He wasn't surprised to wake up alone, but he still felt a bit of — Ah, hell. Pain. 

It was the only way to describe the dull ache in his chest when he opened his eyes to find the Doctor gone. Still, he simply dragged himself out of bed, shrugging his tired body out of  the lingerie he’d slept in and heading to take a shower.

It was all he could do not to touch himself as the water ran hot over the expanse of his bruised, sore body. He couldn't stop thinking about it.

How he had keened and whined as that perfect, bare hand slapped hard against his thigh, leaving a vicious and beautiful red welt in its wake. How that voice had sounded towering over him, purring against the shell of his ear. How it had felt to have him inside of him. 

It had been perfect. The Doctor, his Doctor, had known exactly how Stone longed to be treated. He’d had no qualms about giving him exactly what he wanted. There had been no I don't want to actually hurt you. No weak, half-assed attempts to cause the pain he craved. No wannabe doms with their pathetic attempts to control him when they had not even begun to earn the right. 

Everything that he had been given was exactly what he needed. Rough treatment, the kind that would leave him bruised and bloodied if he was lucky — And oh how lucky he was. He had been a fool to ever think anyone else could even come close. 

And oh… The bites. The bruises. He didn't even begin to mind — The Doctor could mark him up as much as he pleased, but now…

He carried marks of what had happened everywhere. There was hardly an expanse of skin on his body that had not been marked and nipped, deliciously dark bruises patterning as far as he could see and even farther. He would be feeling last night for a long time, and the thought alone sent a perfect thrill running right through him. 

How long had he been dreaming of it? Dreaming of having exactly that kind of encounter with the Doctor?

His only regret was having him wear a condom. Not being able to feel him spill inside him… Stone could have sobbed for the loss of it now. Fuck it, he'd go on birth control if he had to, get his tubes tied, have the whole damn thing taken out — Anything so he could feel Robotnik fill him.

He had to hope that there would be plenty of opportunities for that later, but he had no way of knowing for sure. What if it had been a mistake, one the Doctor regretted from the moment he opened his eyes and left his assistant alone in the bed?

What if that had been his only chance and somehow, someway, he’d fucked it up? Part of him had longed so horribly to be held, after. To feel the Doctor's arms around him, even when the logical part of him knew it would never happen.

It had just been sex, and he was fine with that, no matter what the ache in his heart said. And if it had just been a one time thing, he could learn to be fine with that, too. 

So of course he had expected the Doctor to just leave without a word. Expecting aftercare from him was a joke, really — Of course he harbored no such expectations for his Doctor. The thought alone had made him feel… Vaguely uncomfortable, anyway. Like setting himself up for failure, to hope for more than he would ever receive when hope was already plaguing him enough as it was. 

He most certainly had not expected the man to stride back over and kiss him, let alone to lay down in his bed. He had still kept a distance between them, but… It was better than he could have asked for. Better than he dared to hope for. And he had slowly drifted off to sleep, completely satisfied for the first time in — God, he didn't even know. Had he ever been truly satisfied before? 

Now, he knew that the answer was a resounding no. Of course the Doctor would be the only one to satisfy him.

And there was a part of him that was terrified he would never know that feeling again. 

But of course, he wasn't in love with his boss. He wasn't, he was just… Extremely sexually attracted to him. It was purely sexual, with no emotions involved at all, exactly how it was supposed to be, and yet — 

The Doctor had called him his. He couldn't deny how that thought made his heart flutter in his chest, even now. 

Stone finally dragged himself out of his own head and out of the shower right along with it. He got dressed after drying off, running through the familiar routine of making himself coffee and breakfast. He sat alone at his small table, eating his meal and sipping his latte, scrolling idly on his phone and — 

Dropping it down onto the table and dropping his head into his hands at the exact same time. 

"Idiot..." he huffed, closing his eyes. "I'm such an idiot..." 

Of course having sex with the Doctor was just going to make it worse. It had been bad enough before, but at least he had been able to remedy the urges with the morons at the bar. Now it was just him and this vicious, unceasing want. He was craving having him here all the time. Holding him. Fucking him. Loving him...

And that would never happen. Doctor Robotnik wasn't the kind of man who fell in love.

Stone sighed heavily, leaning back in his chair. He just had to fall for the most unavailable man on the planet, didn't he. He really knew how to pick them.

Running a hand over his face, Stone forced himself to finish his meal and clean up the resulting dishes. He worked his aching body through his usual workout routine, ignoring the sting of the bruises as he did.  

There was no point dwelling on it. He might as well just stick to his usual schedule and keep out of his own head. 

Monday came far too soon and not nearly soon enough. Stone got up early, showered, dressed in his usual suit — Although he left his tie behind on the bed and kept the top two buttons of his shirt undone, displaying the marks on his neck just as he promised. In favor of his usual boxers, he shakily slipped on a pair of lacy panties — Just in case. 

When Stone entered the lab, Robotnik didn’t acknowledge him at all. 

"Good morning, Doctor," he called out, heading into the kitchenette to make the Doctor's morning latte. 

He tried not to be upset that the man didn't even look at him. Really, he should have expected this.

He set to work carefully pouring and curating the coffee with practiced ease, and then returned to the main lab and set the cup on the Doctor's desk with an easy smile. 

"Do you need my assistance with anything in particular?" he asked. If not, he'd attend to his usual daily tasks. No more. No less. 

Or maybe it was always a little bit less. 

Robotnik quirked an eyebrow at the question, but he did not look up.

"Why would there be anything in particular?" he questioned in a bored tone, still working away at the blueprints on his desk even as he took a sip of his coffee. "You are dismissed to your usual routine, Agent." 

"Of course, Doctor." 

Stone felt the sting of rejection running white-hot through his chest, but his expression didn't change as he went about his daily tasks. Idiot. He was an idiot. He never should have let himself get attached, and he had damn well known it, but…

It was the cold ’Agent’ that was affecting him the most, really. The Doctor had dropped that title when they were alone in the lab a long time ago. He couldn't even remember the last time he’d heard it before now, not when it was just them, not by itself. 

Was he regretting what they did? It was one thing to never have it happen again, but to actively regret it… Stone frowned at the thought and, after a moment of hesitation, buttoned his shirt the rest of the way up to hide the marks.

He expected the act to go without notice and, for a while, it did. 

Robotnik had moved from one workstation to the other, enough time having passed for the latte to be long gone, when he glanced at Stone and then back down — And then sharply back up again.

He was on his feet in an instant, eyes narrowing as he closed the gap between them in wide strides and pinned Stone roughly by his hips into the side of the desk.

"I didn't give you permission to cover them, Stone," he growled.

Stone felt his breath hitch, eyes going wide. "I..." He swallowed thickly, meeting the Doctor’s eyes. "I apologize, sir. I got caught up in my thoughts and started thinking… Thinking that you might regret what happened. If so I, didn't want to trouble you with the reminder of it."

Robotnik considered his words with a sharp gaze, quiet and still for one moment before his gloved hands flew up to grasp against Stone's collar. His fingers deftly undid the first two buttons again. Then a third, a fourth, and finally he didn't stop until Stone's entire chest and stomach were bared to him.

Stone waited, body trembling with anticipation as he watched the Doctor take in the sight before him. The bruises that had ever so slightly darkened in their time apart, the patterns of teeth marks and the long red scratches. 

"Did you consider, Stone, that I might simply be trying to do my job instead of spending my entire day admiring you?" the Doctor mused, lowering his head against the side of Stone's neck and slotting his teeth gently against a bruise he had seemed to particularly enjoy placing, if the ensuing burst of pain was anything to go by. 

"N-no, it wasn't that." Stone's breath caught in his throat, but he had been asked a question and he would answer dutifully. "It's just... You haven't called me Agent when we were alone for so long... I'm sorry, Doctor. It just affected me more than I would like to admit."

So maybe he had some insecurities when it came to Robotnik. Sue him.

"It affected you," Robotnik echoed, deadpan as he visibly considered the words. 

A slow smirk spread out across his features as the meaning of what Stone was saying to him seemed to fully sink in, a soft "ah" falling from his tongue, still against Stone's throat.

"Agent," he crooned. "... Is what I called you before you were you. Therefore, a title given to one of my most valued machines. One of my most obedient. So I deigned to use it in my orders for you to get back to work and stop distracting me... Which you have failed to achieve."

As if to prove his point, Robotnik slowly kissed the side of Stone's throat.

Stone gasped shamelessly at the contact, eyes fluttering shut. "F-forgive me, Doctor, it w-won't happen again, I swear..." he said, gripping the edge of the desk tight.

"Oh?" Robotnik purred, pulling away from his neck with a wet little pop. "It won't happen again? You're going to remember your value here all on your own, be good and let me work? And you don't need to be bent over this desk as a reminder?"

Stone hesitated. That… Felt like a trick question. But, fuck, two days had felt like to long without the Doctor's touch… He swallowed thickly, a blush rising to his cheeks.

"… Maybe I need, a little bit of a reminder," he admitted, cheeks flushing red. 

Robotnik sighed. "Oh, Stone... What am I going to do with you?"

On the 'you', he dug one hand sharply into Stone's hip. The other latched onto the back of his shoulder, flipping him over and around with a heavy touch. They both knew damn well that Stone could physically overpower him in a heartbeat, but he clearly trusted that he wouldn't even try as he shoved him down against the desk — And he was right.

Stone couldn't help but moan as he was pinned to the desk, not even trying to fight it. He would never dare.

He tugged his lower lip between his teeth, eagerly awaiting the Doctor's next move. "I'm s-sorry, Doctor," he said, unable to keep the eagerness from his voice.

Robotnik trailed a hand from behind Stone to drag his fingertips across the bruises, humming pleasantly as he felt the welts and raised skin along the teeth marks.

"You're sorry? Oh you sound so very sorry, Stone." 

Stone. Not Agent.

It sent a sickening little thrill down his spine to know that Stone, so confident and taking in the nightclub days before, could be so easily shaken by one little word off the Doctor's tongue.

Robotnik could feel tension and want vibrating through his limbs at break neck pace.

Robotnik grinned as Stone so eagerly responded his every movement. He had long ago deemed sex to be a ridiculous waste of time — It just so happened that he was the smartest man alive, and it also just so happened that he had been so painfully in need of Stone that he had prepared for this possibility in a particularly weak moment quite some time ago.

Even still, he was consumed the urge to punish Stone for making him feel so out of control. 

Deft hands trailed down to undo the button of Stone's pants, quickly finding the zipper next and hooking his hands into his waistband.

Stone hummed in response, arching into Robotnik's touch. He shivered as Robotnik worked his pants down, hoping he liked the little surprise he was wearing. Almost immediately the black lace was revealed, a wet spot already forming on the crotch from how eager he was.

Robotnik's breath hitched so sharply in his throat that it took an entire four agonizing seconds for his brain to kick in and let him remember how to breathe again.

"Oh you little fucking..." His voice was raw as he folded himself down over Stone, slipping his shirt away a bit more so he could bite down on his shoulder. Stone rewarded him by crying out, not even bothering to keep himself quiet. 

His hand slid between Stone's legs, running over him slowly through the lace and breathing out sharply at how immediately soaked his fingers were. 

"I take it you, ngh, like the surprise?" he purred. In spite of the falter in his voice, he asked the question coyly, almost challengingly.

It was like he was just asking to be brutalized.

In response, Robotnik ground his stirring cock sharply against the curve of Stone's lace-clad ass. 

"You were made for this," he bit out. "I suppose that you might as well look the part, too."

With that the Doctor slid his hand abruptly beneath the soaked lace, shoving two fingers harshly into Stone and pumping them without mercy.

Stone moaned loudly as Robotnik's fingers plunged into him, arching and trembling and they worked roughly into him. "Oh god!" he whined, gripping the edge of the desk hard enough to turn his knuckles white. "Yes, Doctor!” 

He gasped and choked for breath, rocking against the fingers inside of him and panting heavily all the while. If it weren’t for the Doctor, it would have been humiliating.

He wasn’t given much longer to reflect on this before Robotnik was bringing his other hand down harshly and suddenly against the side of his thigh, fucking him on his fingers even harder against the pressure of the blow.

"You're dripping on my blueprints," he seethed, but he didn't stop pumping his fingers even as the pool on his desk grew.

Stone keened at the harsh smack to his thigh, moaning as those perfect fingers pumped harder into him. His head fell against the desk as he moaned and whimpered desperately, rocking against the pumping fingers. 

"I'm, ngh, s-sorry, Doctor... Oh god, right there, please!" He babbled as Robotnik's fingers truck a particularly sensitive spot inside him.

"You’re too eager for your own damn good, Stone," Robotnik mused. 

He fucked his fingers sharply into the spot that earned him the prettiest sounds — For a moment. Then he abruptly withdrew, striking his slick hand against Stone's ass and visibly marveling at the fresh red hand print that was immediately beginning to form.

Stone cried out as that spot was abused by Robotnik's fingers, all but entirely sobbing in pleasure. But the sounds were nothing compared to the desperate cry that as the fingers were suddenly removed, before gasping at the harsh smack to his ass, the impact making his hips twitch.

"Doctor, Doctor please,. Please, I need you so bad," he begged, rocking his hips back desperately.

Robotnik groaned in the back of his throat, sliding one hand around to clasp Stone's throat and wrench his head back. Hard enough to hurt, soft enough not to thoroughly gag him just yet. 

"Stop whining." 

The amusement in his voice betrayed just how much he adored it — And so did his abrupt release on Stone's throat, shoving his still-slick fingers deep between his assistant's legs, pumping inside him mercilessly.

Stone groaned as his head was wrenched back, choking slightly and grinning over his shoulder at Robotnik, cheeks flushed red. He panted as he was released, head dropping against the desk. But every bit of it was worth it to feel Robotnik's fingers finally start fucking into him again, a babbled wave of thank you’s spilling from his lips as he continued desperately against him.

Robotnik watched Stone hungrily and eagerly, humming in tune with the low groans spilling from his lips. His assistant was so openly grateful it was hard not to want to reward him, even though he hadn't done a damn thing to earn it.

Another look down at the soaking wet lace covering him made Robotnik rethink that last thought, and he dug his free hand into Stone's hip to angle him just right against the desk as he fucked him against his hand.

"I think,” he breathed, “I can make you cum on every surface in this place.”

Stone groaned and whined as the Doctor's fingers pumped into him, every bit as shamelessly in need for it as he had been when they’d started. He gasped as he was angled perfectly over the desk for Robotnik's fingers to drive against the most sensitive spot inside of him, making him moan and gasp even more desperately.

"Oh god!" He gasped out, arching and clawing at the desk. "Please, I'm so close. Please let me cum, sir, please —!"

Robotnik angled his head to press a sharp bite of his teeth against Stone's back, immediately soothing the marks with his tongue as he steadily slammed his soaked fingers deeper. 

"Now, Stone," he hissed. "Don't hold back on me."

Stone sobbed as he came, , stars erupting in his vision as his orgasm washed over him. He was nearly screaming in pleasure as he arched and writhed against the desk, clenching and squirting around Robotnik's fingers. He trembled all through the aftershocks, breathing hard as he slumped against the desk.

Robotnik withdrew his now-drenched fingers, grounding Stone with both hands planted on his hips as he trembled and shook through it.

"You thinking I could regret this is just further proof of the disparity between us," he mused. "You're perfect when you cum for me."

Stone panted, swallowing thickly. He laughed breathlessly at the Doctor's words. "I'll never doubt you again, Doctor," he promised as he fought to caught his breath.

There was no ignoring the mess he made. Whoops. He had never done that before.

Robotnik latched readily to the expression on Stone's face, tilting his head inquisitively as he dragged his eyes between his assistant and the mess coating his desk.

"Is... Is that new?" he mused, grin already pulling at his mouth.

Stone nodded. "Very new,” he answered. "I've never… Fuck. I didn't even know I could do that. I, ah, should, probably clean that up." He laughed breathlessly, looking at the mess with flushed cheeks. 

Robotnik did absolutely nothing to hide the cocky smirk on his lips, regarding Stone with an uncharacteristic sort of fondness. Reverence, even.

"For the love of god, Stone, don't tell me you've been that pent up for all this time. How many imbeciles have you brought home with you?! You are hardly difficult to please."

Not for him, at least, and he didn't do a damn thing to try and subdue how pleased that made him. He could always tell himself it was still his own arousal speaking, anyways.

Stone chuckled. "I ah… I haven't had much luck finding someone who's able to give me what I need in the past," he said with a nervous smile. "I mean, most of them didn't even manage to make me cum at all, let alone that hard."

Okay, yeah. He'd brought some real losers home during his time going to the club. 

Robotnik's gaze soured ever so slightly. "Get me a list, then," he shrugged after a moment. It was a rather entertaining thought, tracking down every mediocre man who had not even tried to pleasure him in turn.

The thought alone had a strange little wave of sentimentality welling amongst the possessiveness he already felt, and he eased Stone back into the desk, facing him now — and pressed a chaste kiss against his temple.

"I wasn't exactly getting names, Doctor." Stone chuckled, his heart racing at the kiss to his temple, cheeks flushing as he smiled brightly. 

This time, Ivo tapped a finger against his temple. "Not. Hard. To. Please."

Stone hummed softly at the man's pointed words, a lazy smile on his face. "Only for you, Doctor." 

"'Only for you, Doctor,'" Robotnik echoed, a pleased little smirk still playing on his face. "I might not believe you if it weren't for —"

He broke off with a flash of teeth as he motioned across his desk. He started to laugh, but something feral and dark flashed in his eyes at the sight instead. 

"Get back to work, Stone. Before I fuck you on every surface in this damn building and you owe me more replacements for my work than you could ever repay."

Stone felt a pang of arousal at the idea of the Doctor spending the whole day fucking him over every surface in the lab, but he obeyed the order. He quickly pulled his clothing back into place, redoing the closures on his pants and buttoning his shirt back up — Still leaving the marks on his neck exposed. 

"Of course, Doctor," he said.

He cleaned up his mess and went right back to work like nothing had ever happened. If it wasn't for the flush on his cheeks and the rumbled state of his clothing, it would be easy to think nothing had happened. Nothing at all.
