Chapter Text
Robotnik was relaxing in his chair, watching an old episode of La Ultima Pasion while he waited for Stone to get back from his run to the store. He had the AC running due to having felt much too warm all day, and was wearing only his tanktop and boxers, having shucked off his robe about an hour ago.
He reached over to take a drink from his water bottle, only to find it empty. With a frustrated groan, he stood up from his seat and walked to the kitchen, and as he refilled it from the filtered tap, he then realized his boxers weren't damp with sweat. It was slick. A lot of slick. How he hadn't realized until now, he isn't sure. But...fuck, his beloved chair is noticeably wet, and he feels...he feels...
Weird.
Oh, fuck no.
It was with a sudden wave of unbridled need and sheer panic that he remembered he had ran out of suppressants just last night, that was one of the things Stone had gone to get from the store. Shit, shit, shit. Okay, he just has to get a towel for his poor chair, get himself comfortable somewhere, and pray that Stone gets home soon.
He can only hope this will all be over quickly...
-
Stone arrived home from the store about half an hour later, setting the groceries down on the kitchen island as he glanced into the living area expecting to see Robotnik there. When he didn't see the doctor in his chair, an unnecessary amount of panic set in. Honestly though, who could blame him after nearly losing the man three times now?
But then it him: the unmistakable scent of an Omega in heat. He grabbed the suppressants, a few bottles of water, and some of the doctor's favorite snacks he had gotten from the store that day, rushing into the bedroom. He found Robotnik curled up in a poorly thrown together nest, clinging to one of Stone's shirts with the collar pressed against his nose.
"Stone..." Robotnik's voice sounded so desperate, so shaky. So...unlike him.
"I'm here. I'm here, you're alright." Stone said softly, approaching the nest with care. "I've got the suppressants, but I don't know if they'll help now. Is it warm heat or regular heat?"
"Regular." Robotnik grumbled. "My chair is wet."
"It's okay. I can clean it, don't be upset baby." Stone assured him, gently stroking his knuckles with his thumb. "Do you want me to help you through it?" He asked, doing his best to control his body's reactions to Ivo's heat.
"Only if the suppressants don't help." Robotnik whimpered, clinging to Stone's hand.
Stone nodded in understanding, grabbing the bottle of suppressants from the bag and opening it, handing Robotnik the little white pill with a bottle of water. The doctor took it quickly, swallowing it down desperately with the water. Stone knew that the doctor was apprehensive about sexual contact, having had some pretty bad experiences in his youth. Back in those days, omegas were treated pretty terribly, especially male omegas, and especially in Beta run Catholic orphanages like the one young Ivo had been in. In those places, they saw heats as something to 'be taken care of as quietly as possible', which basically meant throwing an omega in a locked room with an alpha around the same age and letting that brutish, cruel alpha have his way with them, telling the poor traumatized omegas that their nature was ungodly, that they were unholy abominations in the eyes of a vengeful God.
Ivo had gotten it the worst, being one of only three omegas, and the only male omega in an orphanage with twelve muscle bound hormonal teenage alphas who could go into rut at just the smallest whiff of an omega in heat. The beta kids knew to stay out of the alpha kids' way, which left Ivo defenseless. Even when he wasn't in heat, those boys would break into his room at night to satisfy their urges, apparently unsatisfied with the two omega girls that were right next door to either side of Ivo's room. As soon as Ivo aged out of the orphanage, he scraped together enough money to buy his first bottle of suppressants and never looked back. University was a breeze when he didn't have to worry about smelling like an omega, didn't have to fear his heat, didn't have those boys constantly ogling him and groping him at every opportunity.
He came out of university after his fifth and final PhD at 25 years old a new man, a beta, a brilliant force of nature. He quickly snagged a job with G.U.N's robotics division the same year, making himself known as the smartest and most terrifying man to ever be in G.U.N's employ. And he had enjoyed over twenty years of his new life and new identity, until he was assigned this one 'beta' agent that was off-puttingly kind and nice to him, bringing him absolutely delicious lattes with steamed austrian goat milk and little snacks throughout the day, always there to hand him the tool he needed and handle the emails from the mouth breathing pentagoons they worked for, and overall just being... soothing, in a way Robotnik didn't initially understand.
Stone had never let on that he knew Robotnik was an omega, but he had figured it out almost immediately, picking up on the faint traces of his scent in the lab, a unique, delicate scent not unlike chamomile tea. The agent did his best to keep this realization to himself, treating the doctor like the beta he clearly wanted to be seen as, just as Robotnik treated Stone like a beta, never suspecting otherwise. The doctor had hated alphas with a vengeance, and had a habit of dismissing alpha agents on that basis alone, but he had secretly been easy on omega agents when they were unfortunate enough to be sent his way, finding actual things to dismiss them over instead of just saying I want them gone because of their secondary biology or they reek of toxic masculinity and it's affecting my allergies.
So imagine his surprise when his sweet, calm, composed 'beta' turned out to be an Alpha. Of course, Stone didn't intend for Robotnik to find out, hadn't meant to show that side of himself to the Doctor ever, but there was a wannabe mugger coming at Robotnik with a knife and murderous intent while they were just trying to take a nice, relaxing walk outside the hotel. Stone didn't even realize he was releasing such copious amounts of threatening pheromones, let alone that he was literally snarling at the attacker, growling about how Robotnik was his omega, his mate, his top priority. Stone had wholeheartedly apologized to Robotnik later, explaining that his unsavory primal nature had taken control, and it wouldn't happen again. Robotnik, though, found himself having positive feelings towards an alpha for the first time in his life. That night, as he patched up the small cut Stone had gotten on his hand from the knife, Robotnik revealed his true designation to Stone, simply saying he'd had a 'less than ideal' upbringing in a Catholic orphanage and that he now hates all Alphas equally. All except Stone, because Stone wasn't like other Alphas. He had a heart, and it was much too big for an alpha, but perfect for Stone. Of course Stone was forced to admit he knew, which shocked and somewhat worried Robotnik, who started thinking his ruse was finally failing, but Stone assured him he just had a particularly sensitive nose and even then, what remained of Robotnik's omega scent was nearly undetectable to him outside the lab.
Regardless, Stone continued treating Robotnik like a beta, an equal, per Robotnik's personal request following that night, but that didn't stop him from bringing him snacks and making him those perfect lattes as his way of caring for him as though they were mates. And when Robotnik was stranded on that mushroom planet, one of Stone's main concerns were over whether the doctor could handle a heat all alone, with no support and no suppressants.
Quick answer, he couldn't. Robotnik's first heat on that planet hit him completely without warning, and he had spent a whole night rutting against the ground while cradling the rock he'd named Stone, biting into the mushroom ground beneath him in a weak attempt to mark 'Stone' as his mate. All it did was leave him with a mouthful of disgusting mushroom cap. His second heat was just as bad, and once he got home, he had tried to get ahold of his suppressants in time, but his third heat hit faster than he could get to them, leaving him stumbling into the Mean Bean and practically throwing himself at Stone despite what had remained of his rational brain screaming at him to stop, no, please, not again.
Stone was worlds different than those boys from the orphanage, though. He was gentle, caring, attentive. Everything an alpha usually wasn't. He asked for clear consent before even touching Ivo, had used protection, had been patient with Robotnik's body, letting him adjust to the size of his member before moving at all, had even asked for explicit consent to knot him, and had held him oh so tenderly while they basked in the afterglow, before asking in the sweetest voice ever if it was okay to mark him or if that was too far for them.
Robotnik absent-mindedly touched the fading mark on his neck, heart fluttering at the memory of Stone gently sinking his teeth into his neck after getting permission, how his heart has soared with what he now realized was love. Stone was laying next to him now, the comforting smell of his natural coffee scent filling the room around them. Stone was simply holding his hand, but this one point of contact meant everything to Robotnik.
"I think we'll need to fix this the old fashioned way." Robotnik murmured, realizing his heat had no intentions of leaving.
"Are you sure?" Stone asked, big brown eyes filled with concern.
"Yes. Besides, you've clearly gone into rut because of me. Now get over here before I change my mind." Robotnik says, gesturing towards the tent in his agent's pants.
"Don't worry. I'll be gentle." Stone whispers, noticing how Ivo tensed up still when he reached out to remove his damp boxers. "I would never hurt you. I could never hurt you..."
And Robotnik believed it, because Stone never had. For the first time in his life, he had someone who wouldn't hurt him, who wouldn't just use him for their own gain, who truly wanted what was best for him, wanted to help him and take care of him.
Someone who loved him unconditionally.
-
A few weeks later, Stone was in the kitchen cooking dinner for him and Robotnik when the older man came up behind him, arms snaking around his waist as he rested his head on shoulder. He smelled sweeter than Stone ever remembered him smelling, it was almost a floral scent, like roses.
"What are you making?" Robotnik asked, nuzzling into the mating mark on Stone's neck.
"Beef stroganoff, your favorite." Stone replied.
"No mushrooms?" Robotnik said. He had always hated mushrooms, even before his stay on that piece of shittake planet.
"No mushrooms." Stone confirmed, grin nearly splitting his face in half. "Your stomach feeling better today?"
"Yeah, I think it was just something I ate." Robotnik replied nonchalantly, taking a seat at the kitchen island. "Which reminds me, we won't be ordering from that taco place again."
"Noted." Stone agreed, although he was beginning to doubt it was food poisoning since he had eaten the exact same thing and didn't get even the tiniest bit sick. "But I still think we should do a test to be certain."
"Stone, there's absolutely no way you knocked me up." Robotnik sighed. "You used protection, and besides, I'm probably too old now anyway."
Stone went silent then, his face oddly awkward and uncertain. "I did at first, but towards the, um...end of your heat and my rut, it was kind of...forgotten, in all the action."
"Well...shit." Robotnik said simply, the realization that he may very well be pregnant right now setting in. It wasn't all that uncommon for Omegas to remain fertile even in older age, but to actually get pregnant that easily? That was downright mythical. It usually took a hell of a lot longer to knock up an omega his age. He was 52 years old for crying out loud, and he could have sworn he had started experiencing pre-menopause symptoms a few months ago.
"I'm sorry. That was completely irresponsible of me. It's all my fault--"
"Agent, shut your gorgeous mouth for once." Robotnik sighed. "Let's just...have our dinner first, and then we'll do a test to see if I'm... pregnant."
"Okay." Stone agreed. "No matter what the results are, I want you to know I love you, no matter your decision, and I'll always be right here to support you. It's your choice, and I take full responsibility for possibly impregnating you. It was careless of me to let myself forget basic protection, and it will never happen again."
"It wasn't your fault, Stone. You were in the clutches of your rut, no longer in control of your own actions." Robotnik sighed, hand absentmindedly resting over his belly, which may just contain their unborn child right now. "Besides, I thought Alphas weren't supposed to take responsibility for their actions during rut."
"I'm not like those alphas, Ivo." Stone reminded him, voice gentle and soothing. "I actually care about my mate, about you. I...I just want what's best for you."
"Start by not letting that burn, Alpha." Robotnik replied, pointing towards the pan on the stove.
"Shit!" Stone hissed out, turning off the burner and moving the pan. "Don't worry. Crisis averted."
Robotnik couldn't help but laugh, revelling in the domestic bliss of his life here in the crab. He could definitely spend the rest of his life here with Stone and their possible child.
One can dream...
-
Robotnik was all nerves as they awaited the results of the pregnancy test he'd taken, bouncing his leg anxiously as they sat together in his chair. Stone was gently rubbing Ivo's shoulder, doing his best to hide what an absolutely nervous wreck he was inside.
Finally the two minute timer was up, and Robotnik took a deep breath before looking at the little white stick, effectively blue screening when he saw two pink lines.
"Positive." He mumbled, still in shock. "I'm... I'm pregnant."
"Oh my God." Stone whispered, tears pricking his eyes. "I...I got you pregnant."
"That you did." Robotnik replied, hand resting over his belly.
"Well...is this a good thing or a bad thing?" Stone asks, squeezing Robotnik's shoulder gently.
"Good thing." Robotnik replied, unable to stem the tears in his eyes. "Very, very good thing."
"So you're keeping it?" Stone asked, his voice soft and disgustingly gentle.
"Of course I am, you moron!" Robotnik snapped unintentionally. "Fuck, I'm sorry. I didn't mean to--"
"It's okay. It's hormones, you're alright." Stone assured him, unable to hide his joy and disbelief.
Robotnik looked down at his belly, gently running a hand over it as the realization that their baby was in there fully sank in. "Our baby's in there." He whispered in disbelief and awe.
"Yes, it is." Stone replied, voice dripping with pure love and adoration.
"Fuck, I'm gonna get even bigger." Robotnik groaned, realizing he would have a sizeable bump on top of the belly he already had.
"Yes, you are." Stone replied, unable to hide just how much he clearly loved that idea.
"Well it's your fault I'm this big to begin with, you freak." Robotnik grumbled, rolling his eyes at his mate.
"Well, you're the one who loves my cooking." Stone reminds him. "Besides, I think you look gorgeous like this."
"Ugh, go to horny jail." Robotnik scoffed, smacking Stone with a throw pillow, causing his mate to burst out laughing.
"How long is my sentence?" Stone asked playfully.
"Life without parole." Robotnik replied.
"In that case, I plead guilty." Stone replied, snuggling into Robotnik's side. "On all counts."
"You truly are obsessed with me." Robotnik sighs, gazing fondly at his mate.
"Guilty as charged." Stone whispered, gently rubbing the belly that contained their unborn baby. "I should be locked up, because I'm pretty sure loving you this much is illegal."
"Don't go stealing all the crimes around here. I have a sizeable rap sheet, too." Robotnik protested. "Fraud, treason, murder, and being disgustingly in love with you, to name a few."
"Maybe we can share a cell." Stone joked, sporting that goofy lopsided grin.
"That would be perfect." Robotnik whispered, cradling Stone's annoyingly adorable little face.
"Still not as perfect as you..."
