Chapter Management

Recovery was hard.

Both physically and mentally. Ivo had never been in more pain in his life than whenever he was in that full body cast for some odd months... (Not to mention the occasional body cramps and pains he was still getting.)

Even worse so, Robotnik had gone... eugh... soft, in a way. He was feeling far too many human emotions since his tragic defeat. Humiliated, embarrassed, disgusted, disappointed... so many negative words to describe his current state of mind. Lonesome was also a word that had strangely crept it's way into Ivo's mindset.

At least he always had Agent Stone around, of course. The man was too loyal to leave. Even if his supposed boss was a fatter, unkempt shell of the once stunningly villainous man Stone had fallen in love with serving. Yet he still stuck around. What a freak.

Ivo wouldn't be able to bear to see Stone leave. He hates to admit it, but the man actually had become invaluable to him over the years. Stone basically did everything around the crab while Robotnik sat on his ass all day. Stone did laundry, dishes, cooked, cleaned, he even did maintenance on the crab whenever needed.

He seemed so happy go lucky all the time, despite everything. If Ivo had to do even the smallest chore he'd carry it out begrudgingly or just blow it off, but Stone did all the everyday chores like it was nothing. He hadn't been letting his agent clean up the area around him lately, it pissed him off seeing Stone so jovially pick up messes that weren't his.

Stone would be fine leaving it for now, not like it even effected him directly, and Ivo got to enjoy basking on his throne (gaming chair) in the middle of his garbage covered floor.

His days mostly consisted of watching anything that would distract him on the large screen in the crab. What he should've been using to pull up maps to track the hedgehog and exact his revenge, he was watching soap operas on...

Well, at the moment he was actually doomscrolling on a new app he found... the title was something or other about a clock. He was still trying to get his recommendation page to actually show him stuff he wanted to see. The app kept showing him lowly humans going about their days, healthy, happy, family filled. It disgusted him...

Maybe he was jealous in a way. These people were living their lives without the shame of losing to a blue space porcupine continuously hanging over their heads. Lucky bastards.

He still watched the videos through of course, glimpsing into the outside world for the first time in a while, even if it was through a screen. What kinds of fools did the people watching these unironically have to be to seriously become invested? Ivo watched these to make fun of the crowd of lower intelligence. No other reason.

Scrolling through a couple's shared page, he'd scoff and laugh at their expense. What a couple of saps, sharing their social media. Robotnik bets that the man had a secret side account he was using individually, probably even talking to other women.

He continued his judgemental escapade of the page until he scrolled onto a video... of a baby? Yes, the couple decided to have a baby, and this was some 'big reveal' of sorts. Suddenly, Ivo's rude internal comments subsided as he just stared, his gears turning.

Why would anyone want to have a baby?

They were just another responsibility. Another mouth to feed. Another living thing to clean up after and take care of. He scrolled further, seeing the infant age slowly over the short videos. The smaller, stupider, predeveloped human took after it's father. The mom filming a video of the man and his baby playing with blocks, the infant babbling.

It was almost...
Cute?

No, he didn't mean that! How grossly domestic it was to care and look after something produced of your own genes... Cloning would be much more efficient.

But as he scrolled and continued, something in him ached slightly, as if he longed for something so... disgustingly saccharine! Despite his left brains protests, his thoughts continued to race.

Robotnik pictured a baby of his own, taking after his appearance...

He quickly shook the thought away. The Robotnik bloodline would end with him, he was sure of it! No woman would ever even approach him with such intent, especially not while he was in his current state. The only other human who'd even touch him whenever he was this pathetic was Stone.

hm.

He filed that realization away for later use. For now, what would an infant version of himself even look like? He had no baby pictures, no memory of mirrors from that early of an age. Maybe it wouldn't look too different from his current appearance!
...

Eugh.
Robotnik shuddered. On second thought he hoped that wouldn't happen.

Continuing on- would he prefer to have a boy or a girl? Would it even matter? He would want his child to inherit his natural penchant for genius tech. Having another parent involved might put that at risk...

Unless said other parent happened to have an IQ of 301 and an engineering degree...

And just like that, Stone came to mind again.

Ivo still wasn't fully convinced that the IQ part was true, his assistant was such an airhead sometimes.

Hmm...

If Stone did have a kid he'd be a great parent. He was already so sickeningly nurturing towards Robotnik, he could easily imagine how lovingly cared for a child of Stone's would be. Ivo's gears churned once more. He turned off the large screen in front of him with a tap on his control gloves.

He was gaining ideas that were too farfetched for his mind to immediately process.

Robotnik now... somewhat, in a way, wanted to have a genius heir to his bloodline. Someone to continue his legacy...

And Stone was 1. The only other human being on earth who likes him. 2. Off puttingly motherly for a man. and 3. Willing to do anything Robotnik requested.

....

He needed to get Stone pregnant asap.

Notes:

First fic, FEEDBACK AND CRITIQUE IS NEEDED I'm nervous about characterization and stuff

Chapter 2

Summary:

97% plot building the rest is sex/j

Notes:

FIRST TIME WRITING SMUT LIKE THIS extremely nervous about this one.

Finally decided how I'm gonna continue this fic, so tags and description will change slightly :)

Dinner time!

One of the only times of day Ivo enjoyed his new pathetic lifestyle. Except today was different. He forced himself out of the comfort of his chair to sit and eat dinner with Stone in the actual dining room of the crab. And now the time that usually would've been spent his to relax and eat Stone's (admittedly wonderful) cooking by himself, was being shared with the Agent.

The air around him was anxiety filled and skittish. How does someone even propose such a question? Agent Stone definitely had to notice something was off about Robotnik's mood, the agent could always tell. At the moment however, he just looks happy that Robotnik is spending time with him.

Eating something other than takeout or fastfood helped to lighten the mood a bit. Just sitting down and eating a homemade meal with one another. It was kind of... romantic? No, that's not the term he wanted to use. He wasn't seeking romance here. Either way, knowing Stone, the atmosphere has a possibility of making him feel a bit more agreeable.

Then again, Ivo wouldn't doubt it if the mad man agreed without needing any persuasion.

They sat in silence for a while, eating, Stone basking in Ivo's presence... Until Ivo himself decides to finally speak up.

"You know Stone, I've been thinking..." He started, waiting for a response before he decided he would continue anything.

"About what, sir?" Said response came far too quickly.

Stone seemed desperate for communication as ever. Was he even ready to discuss this yet? What if Stone was disgusted at the thought?? What if Stone decided to leave him all alone to avoid the awkwardness of living with someone you rejected!?

Robotnik shoved all those thoughts away. He hadn't even started yet! If worst comes to worst, he can play it off as a jest. Yeah, he could just say it was a way of poking fun at his assistant!.. In some twisted, odd way... But twisted and odd had become the norm for them, so this wouldn't be the worst thing to ever happen.

"Well... maybe first-handedly ending my own bloodline isn't the choice I want to make in life..." Here starts the hinting. Stone listened intently as always.

"Producing an heir would be... preferable! Someone to carry on my legacy, inherit my greatness!" Before he got to keep on, Stone's voice broke it's silence.

"You... want to have a kid?.." Stone asked, a bit of confusion in his tone. At least he simplified it for himself.

"Precisely, Agent! I thought: Who better to tell first than my loyal sycophant." Robotnik prayed Stone would start picking up on his implications soon.

No matter how vague he was, Stone is required to know what he's thinking 24/7 without anything needing to be said aloud! That's obvious!

Stone's face had shifted in a way that Robotnik didn't like... he was about to prepare for rejection but... Stone's expression was sad almost. What's the matter with him? Why is he being an idiot!?

"I'll find all plausible female suitors nearby as soon as I can, Doctor..." Stone sighed. He stood up, not finishing his meal, about to dump his plate out and leave to do God knows what.

He couldn't seriously be this stupid.

Ivo let out a loud, dramatically upset sigh of his own, making Stone stop in his tracks while he walked away with edge.

"Are you seriously that dense you groveling fool!?" Robotnik stood up as well, grabbing Stone by the shoulders, forcing eye contact.

The last thing he wanted was confrontation like this, but drastic times call for drastic measures...

"You're the suitor, Stone! You're suited! I have chosen you, you're required to decide whether or not you answer me with agreement!" He shook Stone back and forth through the sentence, emphasizing his words.

Stone was incredulous to say the least, eyes widened a bit, dark eyebrows furrowed in confusion causing the crease in between them to show. His face was as if Robotnik just spoke some undiscovered, foreign language to him with no explanation.

Robotnik couldn't take a rejection like this. He was pitiful enough already, he couldn't imagine Stone's disgust if he didn't agree. Stone would hate him forever, he'd probably leave like how he should have years ago-

"Doctor..." Stone's tone had softened out before he finished his sentence.
"You're being serious, right?"

... Excitement? Ivo couldn't tell the tone of Stones words very well, clearer confirmation is needed.

"Do I sound like I'm joking, Stone?"

Fast recovery! Stone's face reddened slightly. Robotnik's hands had slipped down from his shoulders, now just grasping the agent's upper arms. Stone wished they would slip lower, but he'd keep that thought to himelf.

"And you do have some way to make this possible, yes? I mean, we are both..." Stone trailed off.

Creating a child required reproduction, from a logical standpoint Stone should be laughing in Ivo's face at such an absurd request. But, of course, Stone knew Ivo, and he knew the man probably had some insane idea that would end up working. Not to mention he could never bring himself to ridicule the man he was completely infatuated with. Not when, internally, he himself was shamelessly looking forward to whatever Ivo had in mind.

"Of course I can make it happen. Are you doubting my genius?" Robotnik interrogated.

"Of course not, Doctor!" If it weren't for the topic at hand it would seem like a normal everyday work conversation.

That would've been a much more likely scenario... Robotnik should be ordering Stone to make blueprints for some impossible robot, not something like this.

"Then you're on board?" Ivo's voice was eager in a way it normally wasn't nowadays.

"I'm on board, sir!" Stone answered with a smile and Ivo thought that would be the end of it-

"But it's not some random task you can just pull off on a whim, especially in our situation... Have you even had sex before?" Unluckily for Robotnik, Stone still seemed to have a few more inquiries for him.

"No. I haven't." The response was bland, like he hadn't thought of that even being a factor before hand.

"Shouldn't that be our first course of action?.."

"You want to have sex with me?" Blunt, but a fair question.

"Yes."

Stone couldn't believe he had admitted that. He would've given it a couple more years until he would even tell the doctor he was in love with him. Immediately going into sex AND impregnation was out of his expectations completely. Robotnik seemed much less than upset at the suggestion though.

"I suppose that makes sense... We should at least test the act out first before I go all the way on you and start operations..."

Stone was a bit weary to find out what operations would be done on him... As long as it lead to him being a vessel for Robotnik's heir, he couldn't care less. Even if he doubts the doctor would even tell him what would be done or had been done afterwards, that doesn't matter to him.

Ivo, noticing Stone's mind wandering, shook him again, only once to refocus him.

"I'll relax in my chair and, just this once, I'll let you teach me something." He rushed the middle part of the sentence, refusing to admit Stone knew more about something than he did.

But in the end, to Ivo, social, romantic, and sexual knowledge was all unimportant compared to what he knew. He was a genius (even if Stone was one too), he had no need for social skills!

"Your chair, sir?.." Stone shuddered at the thought.

The filthy thing that his boss had been rotting in for the past months? Even if he wouldn't be the one sitting in it, the setting was much less that preferable... Ivo rolled his eyes at both Stone's tone and expression, grabbing onto the neat collar of the agent's dress shirt.

"You want to make this good for me, yes?"

"Of course, Doctor! It's your first time so-"

"Then we're going to do it where I'm most comfortable. If I say we're doing it in my favorite chair, we're going to, Stone."

There was no room for argument, not that Stone had any. His rebuttal died the second Ivo had tugged on his collar.

"Of course, sir."

Maybe the chair wasn't so bad! At least, that's what he was convincing himself as he followed Robotnik to the room he spent most (all) of his day in.. every day.

Entering the garbage filled room was almost worse than he'd imagined. Getting into a mood in a room like this would be... tough. Ivo refused to let him clean in here. His boss had completely dropped his previous, beloved, strict cleansing policies. He reminisced on how clean and neat Robotnik kept both himself and his surroundings.

If he was lucky maybe Ivo would let Stone cut his, currently long and untamed hair, into the style it was before they encountered the hedgehog. He'd like that. Getting to see the man like that again. Stone shook off the sadness that came with that idea, watching Ivo lay back in his chair.

Stone cocked an eyebrow as Ivo pulled a bottle of lube out of a drawer from the desk next to him and tossed it at the Agent.

"What? I said I've never had sex, not that I don't jerk off, don't judge." Ivo scoffed before chuckling.

The vulgar term made Stone's brow twitch slightly at how improper those words were. Now's not the time to be a prude. He had no room to talk. He's a complete freak, but at least he's an eloquent one.

"Maybe if your good enough I'll let you handle that for me from now on." Despite Robotnik's rude laughter as he said this... Stone would 100% jump at the opportunity if given.

He remained silent despite that fact as he'd begun to unbuckle his belt. Robotnik followed soon after. Only pants off. Seeing each other fully naked was awkward. Duh.

Anyways.

The agent positioned himself in his bosses lap, leaning chest to chest with the man for a second before scooting backwards, giving him space. He couldn't believe this was really about to happen.

Stone's cock was practically pressed to the Doctors, and he was having to physically restrain himself from rutting against the other man. Robotnik's cock was just as marvelous to Stone as the rest of him was. The agent fought the urge to stare at the flushed tip and tuft of hair that ran from his lower base up his stomach. He swallowed dryly before speaking up again.

"Doctor, may I..?" Stone trails off, shying away from the words despite being the more experienced one.

"Hold that thought, Agent." Robotnik held a finger up to keep Stone from saying any more.

Reaching a hand back, Robotnik reclined his chair slightly. At least this... somewhat, in a way, gave them both a bit more space apart besides their flush lower skin. Barely, but Stone didn't mind. The interruption was awkward but social que's had never really been Ivo's strong suit.

"Good idea, right? Anyways, yes Stone, you may do... I don't know, whatever you were planning to do." Robotnik shrugged, growing impatient.

"Right, my apologies, sir." Stone nodded, finally uncapping the lube Ivo had handed him earlier.

He poured some onto his hand before cautiously, very cautiously, taking Robotnik's shaft in hand. The first few strokes were slow and nervous, testing the waters of... giving his boss a handjob. Unbecoming of a (previously) highly esteemed Agent, but necessary on both ends.

Stone's pace perked up a bit as Ivo let out a, very quiet, pleased sigh. He kept a close eye on Robotnik's face, trying to take in what he was reacting to and what he wasn't. Stone thought that his gaze went unnoticed until-

"Can you quit staring. Your eyes are... distracting me from other, more important, sensations." Ivo grumbled, rolling his eyes in annoyance. He turned his head, looking away to avoid Stone's gaze.

Stone didn't respond... Ivo only looked back when the sensation of Stone's hand disappeared and he heard the click of a familiar lube bottle. He was already sufficiently lubricated, what did Stone need that for?..

His question was swiftly answered as Stone dripped the cool gel over his own fingers rather than Robotnik.

"My apologies, sir, I promise I'll continue. Just, give me a second..." Stone spoke so casually as if he wasn't lining two slick fingers up against his own entrance... In front of his boss no less.

Ivo could do nothing but stare (the hypocrite) at Stone's fingers as they slowly pressed inside, making the Agent's breath hitch slightly. Stone bit down on his lip to stifle a whimper. He bet he looked whorish enough, he didn't need to be making any noise to add to the sight.

Stone tried to keep his eyes either shut or off of Robotnik.. even then, he felt the older man's eyes burning into him. Every thrust of his fingers was complimented by the sense of dark eyes tracking along with them.

Letting out a pleased sigh, Stone finally grew accustomed to the feeling, just as he got into a steady rythym Ivo's voice broke through.

"Hurry it up, Stone, I'm not getting any younger here..."

"I know, sir, I'm sorry-"

Stone earned himself the harsh swat on his thigh that came after such an insensitive remark... Only Robotnik was allowed to comment on his own age, nobody else.

Luckily, the light sting that followed was enough to motivate Stone. He pressed his third, and final, finger into himself. The agent leaned forward slightly, resting his forehead on Ivo's shoulder. His face grew hot at the closeness, he felt so light. Thinking ahead, if he was lucky he might be able to convince Robotnik to hold him for a little while after they're finished.

"I'd hate to interrupt your little trip to cloud nine, but patience is a virtue I wasn't born with, Agent. I'll prepare you myself if I have to." The threat was empty, but the mere thought made Stone's face flush.

"Another... Another time maybe..." Stone replied through heavy breaths, usual goofy smile plastered on his face like he wasn't degrading his own image in front of his superior.

He could practically see the embarrassed blush that crept up Robotnik's neck to his face.

Finally deciding that enough was enough, Stone eased his fingers out of himself gingerly. He promptly ignored the embarrassing sound he lets slip out in order to line up Ivo's cock to his entrance.

This was actually about to happen. Years of shameful fantasies and longing had all been leading up to this very thing and...

Before Stone even got to sink down, Robotnik impatiently grabbed at his hips and began shoving himself in.

Rightfully, Stone gasped, grasping onto the Doctor's shabby red bathrobe for dear life. He'd forgotten how long it'd been since he'd actually done this himself...

The stretch was bearable, considering he'd prepared himself, but something about the way Ivo was deliberately pulling him down was throwing him off. Stone couldn't even ask Robotnik to wait for a second before his train of thought was crashed immediately.

Robotnik groaned out. A noise completely inconceivable to him. Keeping his grip on Stone's hips, he pulled him down onto himself in one rough movement. Their bodies now flush together.

A noise akin to a whine escaped Stone's throat as he grabbed onto one of Ivo's wrists to still him. He braced his other hand against the arm rest of the chair they sat in.

"Hold- Hold on..." The agent's voice finally broke through as he struggled to fight off a gasp.

"Right, right..." The 'my bad' in Ivo's words went unsaid, but Stone heard it either way. Whether that was because of his (frightening) natural intuition, or because his head was spinning slightly was up for interpretation.

Stone caught his breath, a shiver going down his spine as he fully assessed his situation. The doctor was fully sheathed inside of him. After so long of dreaming and fantasizing about this moment, he shuddered at the thought of finally getting what he'd been pining for. Though, he should probably get moving before he gets shoved off out of impatience...

Lifting his own body weight up was now much harder than it ever had been before. Ivo gladly assisted, holding Stone by his hips, helping to lift him only to pull him back down. Repeating the action proved to draw out a shaky groan from Stone, so he continued.

In actuality, the sloppy movements and uneven thrusts were driving Stone crazy. He could just shove off Ivo's hands and start up a steady pace himself, but the older man looked eager as all hell to keep control... So, the Agent let him have his fun for now.

Lucky for the both of them, Robotnik was getting a bit winded lifting Stone. Even though Stone was helping him, his arms grew sore with age. He panted lightly, both from the pleasure he was experiencing and the physical workout this was giving him.

Despite making an astonishing recovery, he was in terrible shape athleticism-wise. Stone soothed Ivo's arms back down to rest still on his hips, relieving the older man of the growing strain in his biceps. Taking care of Robotnik had become a natural instinct at this point, one that Stone was happy to bear.

Putting his weight back into his legs, Stone rode his boss slowly. His only goal was to please, to make Ivo feel good for once without somehow accidentally overstimulating him in any way. He was finally getting his chance, and he was going to do it right.

"Fuck... Doctor.." Stone allowed himself to sigh out, his movements gained momentum when the older man's breathing grew slightly less heavy.

The was Stone's warm flesh dragged along Robotnik's shaft every time he lifted up was exquisite. The slight grind of ass onto hips every time he bottomed out was no less stunning. Robotnik had begun to regret neglecting himself of this for so long when Stone had been around (and frankly, wordlessly, begging for it) the whole time.

The doctor could picture it so clearly. A younger, thinner, healthier him from all those years ago, taking Stone wherever and whenever he saw fit. He imagined the noises that would escape Stone as he was shoved against surfaces, under Robotnik's body, under Robotnik's full control.

Ivo was only tugged out of his fantasies when he realized he was hearing said imagined noises right in front of him. He had been subconsciously bucking his hips up into Stone, synchronizing with the set rhythm of movement.

Apparently, also in his haze, he'd hit a rather sensitive bundle of nerves buried inside of Stone's depths. The younger man gasped and whimpered at the feeling and strong legs shook slightly. The stimulus caused him to tighten around Robotnik, still keeping the same speed from before.

Suddenly, very suddenly, a full body shudder wracked through Ivo as he bucked up hard into Stone's prostate. His arms instinctively wrapped around the agent and he dug his nails into his back, meaning to hold him in place. He bucked ruthlessly up into Stone, throwing off their tempo once more, until the pleasure had reached a peak.

Stone merely gasped and muffled a whimper on Ivo's shoulder. He didn't have time to process before the feeling of being filled poured over him. A series of pants and groans and, frankly primal, noises escaped the doctor as he came inside of the man in his lap. Was it too soon? Too early? His care for that flew out the window when the bliss ran over him.

The agent grinded his hips down gently, letting Ivo ride out his orgasm. If he had came too early, it was certainly Stone's fault and had nothing to do with his own inexperience. The agent lifted his hips, Ivo fighting off an overstimulated groan, quickly relieved as his soft cock slipped out of Stone's leaking opening.

He soon regained his bearings and looked down between their heated forms. One thing was able to catch his immediate eye, and that was Stone's, still hard, cock. How could he have been so patient this whole time? Robotnik rolled his eyes and lazily brought a freshly lubed hand upon Stone to wrap around and stroke him loosely.

The action startled Stone as he looked down in shock, like he expected the older man to leave him to deal with his own hardness. The loose hold felt uncharacteristically gentle, and the agent gladly accepted that feeling. Maybe Ivo decided he deserved a bit of pampering.

"I've made my mind up, Stone, I'll get your x-ray's done tomorrow..." The doctors voice grumbled, a bit more gravelly than usual.

X-Ray's? Oh, right, his operation(s?)... The thought had slipped his mind in the extremities. Robotnik continued stroking Stone up and down even as he spoke in a business-like tone. It was like being a fidget toy for the man as he gathered his thoughts.

"Obviously I'll need a bit of time before I start surgeries, so I expext you to do this a lot more for me... even if I can't successfully impregnate you yet, you've proven yourself to be... helpful, for once." The praise was barely there but it drew a quiet moan from Stone either way.

"Thank.. Mgh... Thank you, Doctor..." He spoke in an airy tone, precum dribbling down his tip.

"Eager as ever. Do you like when I talk you through this? When I tell you how 'good' you're doing for me? It's pathetic, really." Robotnik teased him cruelly, but he'd be a liar if he said he wasn't absolutely loving it.

Stone hung onto every single honey-dripped word that slunk out of Ivo's lips, every backhanded compliment he was given made him shake. The doctor's grip tightened on an upstroke and all Stone saw was white.

Robotnik pulled his hand back before Stone had finished... finishing, leaving a cold jolt from the lack of touch as the rest of his release shot onto the doctors stomach. That really shouldn't have been as erotic of a sight as it was, especially since Ivo most definitely hated the degrading sensory of such a thing.

Regardless, they managed to settle, Stone panting and coming down from is orgasm.

"Thank you, Doc-"

"Ah, can it. Help me up, we could both use a shower. Especially after you deciding to make such a crude mess of my persona..." Ivo complained, just like normal, like nothing had changed.

Something about that brought a weird sense of relief over Stone.

"Of course, sir..."
