Alastor was an omega.
Yes, it was true and would surely be quite the shock to anyone that ever stumbled across this little tidbit of information. But of course, no one ever found out. Alastor was careful, organized, he cleaned up his messes and didn’t need anyone doubting who he was. He preferred to keep things speculative, it was simpler that way, he emphasized inconsistencies and seemingly conflicting assumptions. His secondary sex has always a point of pain for the radio demon, he loathed who he was from the moment he began expressing as an omega. Even in hell he still had claw marks from where he had attempted to rip out his own scent glands.
The sweet sugary edge of his own scent made him sick. And he figured it was best to end the problem at the source. It unfortunately hadn’t worked. He had been weak. Unable to get his nails and the sewing scissors that he had stolen from his mother deep enough to remove those god awful things.
“Alastor,” Rosie purrs, putting a steaming cup of tea down as she turns her dark empty eyes onto her sweet, desperate little underling. “You know how I feel about you pacing,” Rosie takes a long thoughtful sip of tea, sporting a ladylike look of disapproval. “It’s unbecoming,” Alastor freezes, the fur along his spine, trailing down to his tail puffs up, his body feeling alight with sensitivity.
“Rosie..” the radio demon grumbles, turning towards his overlord. “Please-” Rosie is quick to cut Alastor off before he can even finish his thought.
“I am not scenting you again, pet,” Rosie replies putting a heavy emphasis on the word again as she had just scented the omega a little under an hour ago. Alastor bristles, both at being referred to as a pet and perhaps more importantly, at the denial of his request. He needed it, needed the eraser of his own sickly sweet scent that always burned brighter during his heat. He craved the bitter smell of dark chocolate, mint and rose that always clung to Rosie’s body. He wanted to suffocate his own scent of sweet cherries, sugar and blossoms.
Perhaps it wasn’t the most saccharine scent one could possess, and certainly not compared to other omegas. But still anything that even gave him the echo of a reminder of what he truly is, was hated and shunned by the radio demon. Alastor’s upper lip twitches, eyes narrowing towards Rosie. Who calmly ignores him. His body felt hot and desperate, he could feel his slick already building up. He was a day or so into his heat which means he disappeared from everyone apart from Rosie. Alastor folds his arms over his chest, looking away from Rosie with a pout, his ears pinned and twitching.
“Alastor,” Rosie grins widely, gesturing her pet over and the radio demon naturally falls into line, he had been following her orders for years after all.
The two of them were tucked away into her bedroom, Rosie was kind enough to provide her dear friend with some privacy and protection during this oh so vulnerable time. But that also means she only had one chair, tucked into the corner. Not far from the window where she could enjoy the sweet sounds of sinner screams alongside her afternoon tea. And the occasional candied finger or eye-infused tart. The single, solitary chair served another purpose as well, it was a reminder to Alastor and anyone else who happened to end up in her bedroom, whomever that rare few may be, that this was her space. He was the guest, nothing more, nothing less.
Alastor stands near Rosie, finally a bit more calm now that she has done something to settle him. Which of course was as simple as telling him what to do with himself. Rosie’s hand sides down Alastor’s back slowly, humming as he twitches from the touch.
“Rosie…” That growl from Alastor may have sounded like a warning, however it was anything but. Alastor had never been treated like this by anyone except for Rosie. The radio demon had never felt like this.. whatever this was for anyone except for Rosie. And he didn’t want it to stop. A sharp whine is ripped from Alastor’s throat as Rosie suddenly grips her pet’s little tail and gives it a soft tug. Rosie chuckles warmly, always so sensitive, this one.
Her hand travels high again, nails stroking over Alastor’s back and shoulders, watching his tough attitude fade away. He still acted like he hated it, or tried to anyways but those needy little bleats told Rosie everything she needed to know.
“You are burning up dear,” Rosie says coyly. Alastor lets out an angry little huff as a reply. “Come on, now, don’t be like that,” Rosie catches Alastor’s wrist, turning him to face her. Alastor’s face warms, it was embarrassing how easily Rosie took control of him, that’s exactly what it was embarrassing. He was the radio demon, he was supposed to be stronger than this. Rosie stands with an effortless grace, her hands flatting over the front of her dress as she moves in one smooth motion.
Rosie’s nimble fingers move to Alastor’s midsection. Watching him shiver with mild amusement as she unbuttons his suit jacket and slides it from his shoulders. Alastor, for his part, stands perfectly still, allowing his overlord to undress him piece by slow piece. Revealing his furry chest and scarred limbs. His belly sucks in a moment of instinct as Rosie’s knuckles stroke over the short fur there, petting Alastor lightly with the back of her hand. Her thumb slips lower, the nail skidding along the elastic of Alastor’s underwear. Her hand slides along her underling’s waist, a nail slicing through the sides of his underwear with ease, letting the ruined fabric flutter to the floor.
“Must you always make a show out of everything?” Alastor grumbles under his breath, his body painfully stiff as he tries to keep from thrusting into Rosie’s hand. She wasn’t even touching him properly and he was already wanting to beg and whine and roll over for her like some common mutt.
Maybe she did have a point in calling him pet, Alastor thinks bitterly. Rosie’s hand slides upwards cupping Alastor’s jaw, his Adam’s apple bobbing in his throat as the radio demon swallows thickly.
“Rosie,” he whispers only to be met with a tightening hand on his jaw and a harsh look from Rosie. “Ma’am,” he repents quickly, his hands curling softly around Rosie’s hips, she raises a sharp eyebrow but allows it. “Please mark me.. I can’t stand my scent, you know that..” Alastor licks his lips, leaning softly into Rosie’s hand.
Rosie hums lightly. “Fine,” she finally agrees to Alastor’s total relief. Rosie’s hand drops away from her underling, crossing the room and settling calmly in her chair, taking a moment to get comfortable.
Rosie finally nods, patting her thigh. Alastor stalks over to her side, carefully easing down onto her lap, his body still a bit stiff. But Rosie doesn’t stand for any of that as she wraps her arms around Alastor’s body, yanking him into her breast, his tail wagging like crazy as he breathes her scent in. Rosie’s hands move all over the radio demon, slow and methodical. Rubbing up against him, touching and squeezing and pulling. Special attention being given to his throat, massaging his neck, leaning in and nuzzling up against him. Rosie lightly tugs at his tail as the radio demon squirms and moans. His little hoofs kicking widely for a moment, only steadied by a heavy hand on his thigh. Alastor was hard, desperately so and he knew Rosie could see it too.
The radio demon felt small in Rosie’s lap, small and trapped yet somehow soothed by that notion. He moans weakly, tail lifting as Rosie slides a hand around his ass, forcing him to slide up closer on her lap. There was certainly no hiding it now, the way his cock pushes up against Rosie’s stomach. The feeling of her own, resting between her thighs, underneath Alastor, brushing up against his ass through her dress. He ruts against it, all instinct and desperation and need.
“Eager today aren’t we? Oh who am I kidding, darling, you always crumble for me this fast,”
Alastor groans at that, denying Rosie’s claims with a soft grunt rather than words. Because as much as he would love to deny it, here with her, he was nothing but an animal. Driven by instinct, by the need to breed, to be knotted. Impregnated, to be a good strong mate for the one woman who actually knew how to put up with him.
Or well he certainly would be pregnant by now if it wasn’t for the magic control that was melded into his womb. Making things more manageable whenever Rosie wanted to finish inside of him, which was perhaps more often than it really should be. Unfortunately it still was imperfect, from time to time Rosie would need to step in and suffocate any little parasite that had managed to settle inside of Alastor. Not that the radio demon exactly minded, he probably would’ve done the same even without Rosie’s interference. Still part of him couldn’t help but wonder, to imagine what growing a little doe of Rosie’s would feel like. But that was ridiculous, utterly absurd. It was likely just his hormones acting up that caused him to think this foolishly. Rosie’s claws sink into Alastor’s back, swirling widely, cutting deep enough to bring Alastor’s attention back to her when his mind begins to wander.
Rosie leans into Alastor who had gone practically limp at her touch, the overlord’s mouth opens, her teeth shimmering in the low light. Alastor’s eyes close as he turns his neck to the side leaving his body open, for Rosie to do as she pleased. And oh does she. Razor sharp teeth cut into Alastor’s shoulder, taking advantage of what was close to her without daring to mark Alastor’s neck. The radio demon for his part revels in the pain, enjoying the sharp sting of teeth cutting into flesh, the clear and complete control that his overlord had over him. Well he was enjoying it until Rosie pulls back, letting out a soft tut of disappointment.
“What have you been eating, Alastor?”
The deer grumbles, looking towards Rosie with annoyance. “What?”
“What have you been eating dear? Your blood tastes terrible!”
Alastor grumbles, his ear flicking. “It’s fine,”
“Hardly!” Rosie shakes her head, sliding Alastor off her lap and onto the floor, resting on his knees in front of her. “Goodness, how many times do I have to tell you? You need to be more selective about your prey! I can’t have a pet with such horrific taste! Eating any junk food he comes across,” Rosie stands up slowly undressing not far from where Alastor was still kneeling. Waiting as patiently as he could, despite his twitching tail and ears.
“What a world I live in, not even being able to sample from my own underling,” Rosie murmurs as she slides her clothes off, shaking her head in such total disappointment. Finally she sits back down in her chair, completely nude now, though the way she was sitting would suggest the opposite especially when compared to Alastor’s own slumped in form. She sat, perfectly poised, in total control and comfort at the moment, in spite of her nakedness.
Rosie’s hand curls around her own cock, her legs parting gracefully allowing Alastor to settle between them. His knees had started to ache, the hard floor biting into them ruthlessly but at the same time he felt hopelessly devoted. Stuck on the ground, kneeling for his overlord as he allows her cock to slip into his mouth. Alastor’s tongue curls around Rosie’s shaft, his head bobbing slowly, still being careful of the back of his throat. Alastor was delicate in that way, he could only take so much. And his darling overlord always had a bit more than he could handle.
The radio demon pulls his mouth off of Rosie’s cock, panting weakly. A thin line of pre-cum and spit stretches between Alastor and his overlord’s tip, finally breaking as Alastor turns his head to press kisses up Rosie’s thighs, his hand already replacing his mouth’s place on her dick, stroking her wordlessly. Alastor’s hand strokes up and down with practised ease, long taught exactly how to properly behave. Alastor shifts on his knees, pressing closer to that lovely cock, his hand stroking the base as he focuses his mouth on the underside. Licking, mouthing and kissing it, his chest brushing up against Rosie’s chair. Rosie for her part was simply enjoying the view, deep scarlet eyes were shiny with need, he was trying so hard to be so good. It was adorable seeing Alastor, the radio demon himself work this hard for anything, let alone cock.
Alastor’s mouth returns to Rosie’s tip, his tongue flatting against her cockhead, licking further down her shaft. Before finally sinking Rosie past his lips again, sucking at her lightly as he strokes his mouth over her dick. The overlord above the radio demon suddenly lifts a hand, sinking her claws into his hair, petting his ears. Her hand curls under her pet’s jaw, lifting his head up. Letting her cock fall from Alastor’s lips once more, twitching a little, being so wet and well looked after thanks to the deer under her.
“Do you want it, dear?” Rosie purrs, her voice higher as if she was talking to a puppy. Then again with how fast Alastor’s tall was wagging, perhaps she was. “Mhh? Do you want my knot, darling? Do you want it deep inside of you, stretching you full?”
Alastor nods, his mouth going dry from excitement.
“Yes,” he growls, his voice both hoarse and needy.
“Yes, what? Manners, Alastor,” Rosie reminds her pet, as she so often had to, giving one of his ears a fast, harsh tug. Alastor groans, getting off on being pushed around.
“Yes, ma’am,” he purrs, his voice suddenly pleasant, throwing a quick ‘please’ on there for good measure.
“Better,” It was all the praise that he was going to get, there was always room for improvement after all, especially when it came to Alastor. Rosie rises up from her seat, crossing the room to her bed, Alastor scrambling to catch up to her sure movements. Soon Alastor is belly up on Rosie’s bed, stretching out and snuggling in as much as he is allowed. Being so utterly surrounded by his overlord’s scent had him dizzy. Rosie’s fingertips trail up Alastor’s belly fur, stroking and petting him before finally, finally grabbing his ankles, lifting and spreading his legs open. The radio demon’s eyes flutter shut, a warmth of embarrassment flushing over his body, causing all his fur to stand on end.
He was just so utterly exposed, held down and open. It wasn’t fair how much it felt like Rosie changed him, she always seemed to know him better than Alastor knew himself. It had felt like that since the beginning, all the way back when they first made their deal. It was like a piece of her magic had sunk deep inside and gotten stuck somewhere between his ribs. Alastor had hated it since the start, but he also couldn’t deny how good it felt. How forceful she always was with him. His own whine pulls him from his memories, Rosie having stuffed his hole with two fingers. He was thankful for the touch but it didn’t fill him nearly as much as what he was hunting for. Alastor’s hips thrust up, his body shivering as he clenches down on those two cursed fingers. Hissing out the word ‘no’ as he claws at his own furry ears. He needed more, he had been promised a knot, her knot. And yet here he was still getting teased, his instinct being taunted and waved in front of his face.
“PLEASE!” Alastor cries out, his nails scraping against Rosie’s flesh as his hand snags on her arm, trying to pull her fingers out and tug her over his body all at once. His fur was drenched with sweat at this point, he had been so good! So patient and obedient! So, so terribly good. Alastor’s legs shake as he lifts them up, pulling his knees to his chest, showing off his hole in the best way he knew how. “P-please, Rosie, p-please… I-I need this..” He whispers, his voice broken and weak.
“Oh come now, pet don’t work yourself up into a fit now. All you had to do was ask,” Rosie slips her tip into Alastor, shoving in deep, making Alastor squeak out like the little doe that he was. Roise grabs Alastor’s legs, her palm fitting in between his calf and thigh, perfectly. Alastor’s hands fly about, grabbing at the bedsheets, he should’ve known better than to present himself like that, pinned down and open. Letting Rosie fuck so completely deep into him.
Every little noise that was driven from the omega was high and bright. Whines and cries growing louder with every hard thrust into his poor hole. Neglected for so long just to be torn open and used like this.
“I-I.. R-Rosie.. mhh ma’am,” Alastor pants, his belly twisting.
“Hush dear, you can handle it,” Rosie coos, stroking Alastor’s cheek, her thrusts speeding up, hitting just as deep and cruel every single time. Alastor’s eyes roll back, his fists clenching as he tries to keep from cumming right then and there. Finally getting what he wanted and so much of it as well, so utterly harsh. Unfortunately for Alastor, his overlord wasn’t one to let him off so easily. And yes, this was easy, if he could still form basic thoughts then she wasn’t pushing him nearly far enough.
Alastor lets out a broken sob as Rosie reaches for his cock, as if he needed any more stimulation right now. Her hand strokes slowly, her palm twisting over his aching tip. Alastor sobs loud and openly now, it feels so good that it hurts and because the world was cruel the pain only made Alastor enjoy it even more. It was an endless abusive loop, eating itself, driving any coherent thoughts out of his melting mind. His mouth was wide, drool dripping down his lips, his body flinching and shanking. He would probably be curled up in a corner right now if Rosie wasn’t holding him still. He didn’t want to cum just yet, he wanted to hold on, desperately he did, but there was nothing he could do. With both Rosie and his own body working against him like this.
With a final light squeeze to the radio demon’s cock he cums, and with how he was practically folded in half at this point he ends up blowing his load all over his neck and face. He whimpers, his body weak and limp, all the fight (quite literally) beaten out of him.
“Always making such a mess,” Rosie coos, slowly pulling out of Alastor and allowing him to relax over the bed. Before grasping his hips and flipping him over onto his belly. As lovely as he looked, fucked out and covered in his own fluids, Rosie didn’t want to break her toy! Well not yet at least. Turned over onto his stomach unable to see his overlord anymore a flare of panic washes over Alastor. As he fears that Rosie might already be leaving him.
He knows he was weak, he knew he came too early but surely she wouldn’t leave him just yet would she?
“Ma’am.. p-please don’t… don’t leave.. I-I’ll be good,” tears of overstimulation trickle down Alastor’s face, mixing with cum and sweat. That obnoxious smile however, still holds, however weak. “I-I’ll be so good, please.. p-pleaseee,”
Rosie chuckles, “oh shush my little deer, we’re far from over.”
“Y-yes!! Yessss,” Alastor bleats out, as Rosie’s cock slips back into him, her hand curling around his tail. The radio demon babbles ‘thank you’s as his overlord thrusts into him over and over and over. Focused more on her own pleasure now. She squeezes at Alastor’s hips and ass, making him weakly clench with every sudden touch.
It doesn’t take long for Alastor to cum again as he feels the beginnings of Rosie’s cock enlarging inside of him. The base of her hilt swelling with her knot. Sweet taunting murmurs, that Alastor couldn’t even begin to make out as everything swirls around in his head, begin to fade away. Rosie was close and she could feel it, just a few more thrusts away. Her teeth grit, claws sink into furry hips and will one final push her knot pops into place and she fills Alastor with hot, heavy cum. Rosie hums lowly, as she gives more than she expects to. It turns out all that whining and moaning from her little omega worked her up quite a bit more than she thought it did.
Alastor could feel it too, that heavy load pushing out and filling his stomach. He groans, burying his face into the blanket underneath him. God he was tired but his body kept twitching and squirming, so oversensitive that he couldn’t sleep. Rosie however was unbothered by this, sinking down into the bed next to the sinner that she had just filled so completely. Besides her cock still being firmly trapped inside of Alastor she felt rather warm and comfortable. Swiftly falling into a light, easy sleep. One that Alastor would be sure to complain over once she woke. Which would naturally only cause Rosie to remind her dear underling that he was the one that had begged and pleaded to be utterly ruined. It wasn’t her fault he had such a terrible habit of biting off more than he could chew.
