Chapter Text
For once in his life, Lucifer wasn’t running late for dinner with his daughter. He’d checked his calendar several times to reassure himself of that, but he was not late. Charlie, however, was. She hurried into the restaurant nearly ten minutes after their planned meeting time, but (to Lucifer’s alarm) she wasn’t alone.
His gaze shifted from his harried looking daughter to the man who strode in behind her, his eyes narrowing as he took him in. Charlie hadn’t mentioned she was dating someone new and, more alarmingly, he looked at least ten years her senior.
He was taller than Charlie, which meant he was over six feet, with far darker skin than his or his daughter’s. His curly dark hair was just this side of needing a trim, but looked well-maintained otherwise. Much like his clothes. They were fastidiously cared for, but clearly hadn’t been tailored to fit him. Off rack, perhaps.
He wore brown slacks and a matching sweater vest with a slightly too big button up underneath. Hazel eyes met his own icy blue from behind half frame glasses, their keenness in direct contrast to the placid smile he wore on his face.
“Dad!” Charlie called as she threw her arms around him. “I am so sorry for being late! First my car wouldn’t start and then my phone died and I couldn’t remember your cell number! I was so lucky to run into Professor Hartfelt! He was able to give me a ride here! I just knew you’d worry otherwise!"
Professor? That hardly seemed appropriate… His distrust of the man compounded as he gave him another thorough once over.
“That would be me,” the man offered. He had a good speaking voice, nice and rich, like a performer’s. He extended his hand as Charlie leaned back. “Alastor Hartfelt. I’m Charlie’s psychology professor. A pleasure to meet you, Mr. Morningstar! Quite a pleasure!”
Now that he was close enough, he took a slow breath in through his nose to catch the other man’s scent. He was expecting Alpha or perhaps Beta with the confident way he carried himself and the ease with which he interacted with himself and his daughter, given they were both Alphas.
He narrowly avoided wrinkling his nose when he finally did catch his scent. Having been around for several centuries, in addition to not being human himself, Lucifer had a far keener sense of smell than most. However, he’d never smelled anything like the man in front of him and part of him hoped never to again.
While he thought he caught the barest hint of peat and…something else, an acrid, chemical scent eclipsed both. Likely a cologne of some kind. It probably smelled less potent to others, leaving them able to enjoy whatever it was supposed to smell like.
Oddly enough, Lucifer’s dragon surfaced within him, studying the man through his eyes. For the barest of moments, Alastor froze, his hand tightening around Lucifer’s. But rather than pull away as most would, his pupils blew wide and his nostrils flared.
Prey, his dragon insisted, his Alpha pheromones growing more pronounced. Charlie shot him a curious glance while Alastor’s eyes briefly went unfocused, a shiver passing through his lean frame that was so subtle, Lucifer was only aware of it because he still held his hand.
Alastor’s smile tightened as he withdrew his hand from Lucifer’s. “Now that I’ve safely delivered young Charlotte, I’ll be on my way!”
“No!” Charlie protested. “At least let me buy you dinner to thank you! You said you would!”
“My dear, that was solely so you would stop fretting and allow me to give you a ride. It would be inappropriate of me to impose on you. Besides, I’m sure your father would much prefer to spend the time with you.”
Then why had he come inside in the first place? Unless he (rightly) assumed Lucifer would want to know why his daughter smelled so strongly of…whatever the other man was.
“Enjoy your evening,” Alastor insisted as he turned to leave.
Lucifer’s dragon reared up, compelling him to grab the man’s arm before he could go. Alastor immediately halted, muscles tensing beneath his hold. He met Lucifer’s eyes again, his own widening.
“Stay,” he ordered, unintentionally dipping into his Alpha Voice.
The other man’s breath hitched, his scent spiking.
Lucifer drew in another slow breath, trying to parse his scent out from beneath the chemicals masking it. Something sweet lurked there, buried deep. He longed to press his face to the mating gland on his neck, to hold him in place beneath him and—
“Dad!” Charlie protested, scandalized. “You’re not supposed to use your Alpha Voice on people! Besides, Professor Hartfelt is a Beta. It won’t work on him anyway!”
He blinked, wresting control back from his dragon. Lucifer couldn’t remember the last time it overpowered him like that. For his part, Alastor had yet to pull away either, staring fixedly back at him.
“I… I’m sorry, what were we discussing just now?” Alastor asked, brow furrowing as he glanced between father and daughter.
Stay, Lucifer’s dragon repeated, thankfully not aloud this time. Too thin.
The fuck?
Still, as Lucifer studied the Beta, he found himself inclined to agree with his dragon’s odd assessment. “You were joining us for dinner.”
There was the briefest flicker of confusion across Alastor’s face, but he nodded. “Ah. Right.”
Charlie shot him a questioning look but he didn’t seem to register it.
Lucifer reluctantly released his hold on him, pulling a chair out for Alastor and another for Charlie. The professor tentatively took his seat as he thanked him, perching on the edge of it as if ready to flee at a moment’s notice.
His dragon did not care for that at all.
“Actually, dad, I’m going to run to the restroom but I’ll be right back,” Charlie said as she nudged her chair back under the table and stepped away.
Alastor watched Charlie go with a small frown. “I really don’t want to interrupt your time together.”
“You’re not interrupting,” Lucifer insisted. This time he intentionally tapped into his Alpha Voice. “Relax.”
It took a moment, but the lingering tension melted from the man’s frame and he settled more comfortably in his chair, much to the delight of Lucifer’s dragon.
A Beta shouldn’t act like this. Shouldn’t be influenced by Alpha Voice. However, the alternative was equally unlikely. An unmated Omega of childbearing years working as a university professor, especially somewhere as prestigious as Pentagram University.
And yet…
“You seem very young for a professor,” Lucifer offered, hoping to get him talking.
“I’m thirty-five,” Alastor answered, frowning again.
Fifteen years older than Charlie.
Fifteen years from the point he’d likely no longer be able to conceive.
Unmated. Unclaimed, his dragon insisted. Lucifer wasn’t yet as certain as his dragon that Alastor was an Omega, but he was inclined to believe it. A pretty, young Omega playing at being a Beta… Adorable.
Alastor’s frown deepened as he studied the table as if it had personally offended him. He may be susceptible to his Alpha voice, but he was strong. In all fairness, there weren’t many Alphas as powerful as Lucifer.
“Have you been here before?” Lucifer prompted, fingers twitching with the urge to reach across and settle his hand over Alastor’s, where it rested on the tabletop.
“No. Charlie mentioned you come here often.”
He nodded. “Their tarte tatin is the best I’ve ever had.”
“I’m not much one for sweets.”
He reared back as if he’d been slapped. “Not one for sweets?!”
Alastor shot him what almost looked like an annoyed look. Were he not trying to be polite, of course. “Last I checked, it wasn’t against the law.”
“It should be.” Maybe that was why the other man was so thin…
The professor shifted in his seat, taking out an antiquated smartphone and frowning down at its screen. “While I appreciate your offer to join you, I have somewhere I need to be.”
However, he didn’t push away from the table or stand. The command still had him in its grip. It was the only thing keeping Lucifer’s dragon from causing a scene and grabbing hold of him to force him to stay put.
“Let me buy you dinner at least,” Lucifer insisted.
Alastor was actively fighting the command now, his jaw tightening and the skin around his eyes tightening. That wouldn’t do at all.
“Please, Professor Hartfelt? Stay for dinner.”
The tension in the rest of his face deepened, even as Alastor’s jaw relaxed. He sucked in a sharp breath as he caught on to what was happening. Lucifer doubted he’d call him out on it. To do so would be to admit he was susceptible, among other things.
The man surprised him, however, by leaning forward to hiss, “Stop that!”
Lucifer’s brows drifted to his hairline. “Stop what?”
Hazel eyes narrowed back at him. “You know what.”
“Do I?”
He bared his teeth in answer and Lucifer was stunned to feel a hint of arousal at the gesture. An Omega should always submit to an Alpha, yet here this secret Omega was, openly challenging him instead. His dragon rumbled its approval at the display.
Adorable.
“Care to explain why you’re having such a hard time resisting?” Lucifer added, grinning back at him. “You’re a Beta, aren’t you?”
He opened his mouth to reply, only to snap it closed again as Charlie rejoined them.
“Sorry about that! Have you both already ordered?”
“Not yet,” Lucifer said as he handed her a menu.
Alastor turned his attention to her, offering a faint smile. “Charlie, dear, would you be so kind as to excuse me? As much as I appreciate your thoughtfulness, I really have somewhere I must be going.”
Oh, he was good… Lucifer couldn’t say whether or not another Alpha contradicting his order without the use of their own Alpha Voice would work, but it was a valiant attempt nonetheless.
“Oh! I completely forgot that you were going out of town for the next few days!” she said, hands flying to her mouth, “I am so sorry, Professor Hartfelt! I hope I didn’t make you late! Can I at least walk you back out to your car?”
Alastor’s brow furrowed. “That’s very kind of you, but unnecessary.”
Lucifer drew another breath through his nose. The chemical smell surrounding him had faded significantly, and the sweet scent of ripe strawberries was quickly overwhelming it. He forced himself to remain still and to keep his expression neutral as all of the pieces fell into place.
He must be on heat suppressants. Not that they were the most reliable of medications, given they were illegal. Lucifer gave him a quick up and down, noting the newfound flush to his face and the faint sheen of sweat on his forehead,
His suppressants were failing and they were failing fast. Other diners had begun to take notice, heads lifting and nostrils flaring.
The right thing to do would be to contact the Omega Registry to come and collect the young professor. He wouldn’t be forced to spend his heat with anyone, but they had plenty of ways to encourage him to pick a partner.
His dragon did not approve of anyone else touching the Omega.
Lucifer moved to his feet, taking his car keys out and handing them to Charlie.
“You’re not looking so good, Al,” he said as he did so. “Let me give you a ride home. Charlie, is that all right with you?”
Her face pinched with worry. “Oh! You should’ve said something, professor! You are looking kind of feverish.”
“Let’s go. Charlie, I’ll make this up to you, all right? For now, you can use my car. I’ll drive Al’s.”
“You most certainly will—“ Alastor trailed off with a startled squeak as Lucifer wrapped his hand around his upper arm and effortlessly hauled him from his seat.
He staggered after him as Lucifer towed him to the door, unable to pull his arm free despite how hard he tried.
“Let go of me!” Alastor demanded the moment they were outside and away from an impromptu audience.
“Your heat suppressant is failing,” Lucifer replied as he followed his nose to the older Cadillac that smelled strongly of his Omega.
Alastor’s eyes went wide before he quickly schooled his features. “What do you want? Do you expect me to just open my legs for you because of it?”
His dragon very much approved, sharing mental images of all the ways he could claim the surly Omega. Lucifer shoved them to the back of his mind, lest he bend Alastor over the hood of his car right there and then.
“I expect you might not be able to make it home before it hits and that you’d prefer that didn’t happen in a public space where your little secret would get out.”
Alastor’s expression became guarded. “Are you trying to blackmail me?”
“I’m trying to help you,” he replied as he retrieved the Omega’s car keys from his pocket. “Get in the passenger seat.”
The closer he grew to his heat, the more susceptible he was to his Alpha Voice. Judging from his startled expression when Lucifer started up the car, he was already in far deeper than he realized.
Lucifer cranked up the AC, offering what little relief he could. Gold would be better. He could take the Omega to his hoard and help him through his heat there.
And keep him there, a treasure amongst treasures…
Alastor slid out of his jacket, loosening the top few buttons of his shirt as his body temperature rose. Their mingled pheromones began to fill the car. Alastor’s strawberry and peat scent grew crisper and more intoxicating as the heat suppressant burned out of his system, Lucifer’s mulled cider and sunshine becoming more pronounced in answer.
Lucifer had to force himself to ask, “Is there someone who typically helps you with this?”
“What?” Alastor prompted, subconsciously leaning closer to him. His pupils were already dilated and the smell of fresh slick further enhanced his unique essence.
If Lucifer were younger and less in control of his dragon, they wouldn’t have made it out of the parking lot. Even now, he wanted nothing more than to pull the car to the side of the road and mount the Omega in its back seat.
There were far more comfortable places for that sort of thing. Places they wouldn’t be disturbed.
He cleared his throat. “Someone who helps you through your heats?”
It took a moment for the question to register, at which point he shook his head. “I don’t have heats.”
It shouldn’t surprise Lucifer that the Omega relied so heavily on suppressants. He’d have to in order to keep his secret, especially if he didn’t have an Alpha to rely on. That was another reason for the registry. Omegas were known to seek out whichever Alpha was closest, and it led to more problems than not between surprise pregnancies, ruined relationships, and physical and mental harm to the Omega in question when they came out of their heat.
“Let me rephrase that. Have you ever actually experienced a heat?”
He gave a slow shake of his head and Lucifer’s hands tightened on the steering wheel. That left them with very few options that were quickly whittling their way down to one.
Lucifer could try to find an Alpha like Charlie who was drawn to Alastor in a different way. Judging from the little he’d witnessed, the fact he wasn’t her preferred type of partner helped her keep her head and her distance. She was more invested in caring for the Omega and seeking his praise and approval than in mounting him.
But that wouldn’t protect Alastor from other Alphas with different inclinations. It wouldn’t stop the Omega from wanting to be knotted at this point either. Not being able to satisfy that primal need would prolong his heat. Besides, an Omega had to have a very close relationship (usually shared blood) with an Alpha for something like that to temper their instincts.
“Do you have any family nearby?” he tried.
Another shake of his head.
“Are there any Alphas who know your secret that you’re close to?”
“No one knows. Except you.”
That sent a lance of want through him and Lucifer forced himself to loosen his grip on the steering wheel, lest he crush it. “It sounds like you have two options then. I drop you off at one of the Omega Registry run sites and blow your cover, or I keep your secret by spending your heat with you.”
The scent of slick grew stronger as the Omega squirmed in his seat. “I don’t… I… My suppressants?”
“It’s too late for those now. Besides, it seems like you got a bad batch or they aren’t working for you anymore. It's possible you somehow have an iron will and can keep yourself from running around and fucking any Alpha that’ll have you, but I don’t recommend going that route without supervision.”
“It’s so hot,” Alastor whined in answer, tugging off his sweater vest and loosening a few more buttons to expose the undershirt he wore underneath. His scent grew stronger and Lucifer pressed his foot more firmly on the gas, deciding it was worth it to break a few rules of the road if it meant getting the Omega somewhere safe and private before he wound up with him in his lap.
He didn’t ask where he lived, defaulting to his own home instead. It would be safer. He had no immediate neighbors, and he could ensure his Omega was properly taken care of there between himself and his staff.
The fact it meant he could sequester him away in his hoard was just a convenient coincidence…
Lacking his own car and the remote control inside it, Lucifer opened the gates to his manor with his magic upon reaching them. By the time he parked in his garage, Alastor was down to his undershirt and slacks and was fighting with his belt.
Lucifer climbed out and made his way to the passenger side, opening the door and lifting the Omega into his arms. Alastor made a soft, startled sound, reflexively wrapping his arms around his neck before burying his nose in the scent gland at the side of Lucifer’s throat.
“You smell good,” Alastor purred, nuzzling the spot and inhaling deeply.
Lucifer’s cock strained against his zipper as he power walked through the house, making a beeline for his bedroom. His dragon, meanwhile, loudly protested they should be going to the hoard.
Lucifer tried to set him down on the edge of his bed upon reaching it, but Alastor clung to him with a surprising amount of strength for an Omega. He pressed him onto his back instead, watching hungrily as his eyelids fluttered and the scent of his desire spiked.
The Omega was deep in his instincts, already baring his throat and mate gland as he spread his legs. Lucifer’s teeth ached with the need to bite down and properly claim him. This was the exact reason Omegas wore collars during their heats, to protect themselves and others from unplanned and unwanted bonds.
Lucifer focused on the gold sigil ring he wore, tapping into the magic that tied him directly to his hoard. It hadn’t been cheap or easy to set up such a thing, but gods it had been worth it. With it on his person, he could transport things (and himself) in and out of his hoard. Otherwise he could summon the entrance to his hoard like any other dragon, but he had to physically open it.
As badly as Lucifer’s dragon wanted to claim him, he was old enough to resist that impulse. For now. Still, better safe than sorry. He summoned a delicate, jeweled Omega collar from his hoard around Alastor’s neck to lessen the temptation.
Alastor’s brow furrowed as he reflexively reached for it. Lucifer caught his hand, offering him a wide, toothy smile.
“If you want me to mark you, treasure, you’ll have to offer up that pretty little throat when you’re not mid-heat. Now, how many partners have you had before?”
His face flushed as he averted his gaze. Lucifer’s dragon reared up again, salivating at the implication.
“I’ll be your first?” he continued as he stared down at him, knowing his eyes were far from human at present.
“I…” Alastor swallowed hard. “I couldn’t risk anyone finding out…”
“Oh, I am going to ruin you,” he breathed, wisps of smoke curling from his nostrils. “Unless you have any objections, I’m going to undress you now.”
“N-No objections.”
Lucifer grinned as he helped him out of the rest of his clothes, leaving the Omega deliciously bare beneath him. He almost brought his slick soaked boxers to his nose to inhale his concentrated scent, but banished them to his hoard before he risked any further slips in control. He made quick work of his own clothes after, preening as Alastor stared up at him, eyes wide and desire rolling off of him in waves.
“Now, treasure, have you ever touched yourself?” he murmured, lips brushing the shell of his ear.
Alastor’s breath hitched and he gave a tight nod.
“Good. Show me what you like,” he said as he leaned back to watch.
The Omega tentatively placed a trembling hand between his legs before pressing one of his fingers inside with a soft, choked sound that went straight to Lucifer’s cock. Under his watchful eye, Alastor slowly pumped the digit in and out, whining softly as he did so.
When he didn’t add another and he didn’t touch his clit, another realization dawned on Lucifer. “You only do this around your heats, don’t you?”
The suppressants prevented him from going into a full heat, but if this was the only way he knew to pleasure himself, he must still experience an increased libido during his cycle.
Alastor gave another nod as he began to move his finger faster, desperately searching for relief.
“Oh, dearheart,” Lucifer murmured. He pressed his thumb to the Omega’s clit, rubbing firm circles against it.
Alastor’s body abruptly seized and he sank his finger inside himself as deep as he was able as a startled moan escaped him.
“So sensitive…” Lucifer gently took Alastor’s hand in his, cock twitching at the pitiful whimper he gave when he was left with nothing to bear down on.
“Don’t worry, I have you,” he insisted, pressing two fingers inside of that tight, wet heat and continuing to rub his clit as he guided him through the aftershocks of his orgasm. The Omega’s walls clamped down hard on the digits and Lucifer could only imagine how they would feel around his knot. “That was good, but not enough, hmm?”
“Please,” Alastor breathed. “Please, I n-need—“
“I know what you need,” he said, settling between his legs.
The brush of his tongue across the sensitive bundle of nerves had Alastor’s back arching off of the bed. Lucifer grinned, adding a third finger and slowly pumping them in and out. Alastor writhed on the bed beneath him, chest heaving and heels digging into the mattress as he rocked back against him.
“Please!” he all but sobbed, and who was Lucifer to deny him?
He wrapped his lips around his clit, humming as he added a fourth finger. Alastor clutched the sheets for dear life, tension rapidly building again in his wiry frame.
Just as he reached his peak, Lucifer eased his hand fully inside him, stretching him wide to simulate a knot. This time Alastor did sob as he bore down on it, his entire body jerking with his release.
This should return some of the poor thing’s faculties, albeit temporarily. They had several days to go before he’d fully escape from the clutches of his heat.
Lucifer could tell the moment clarity returned for the Omega, the tension in his body now having nothing to do with impending orgasm. He made to pull out of him but Alastor caught his wrist before he could, face burning as he looked anywhere but at him.
“You need my knot?” he teased, only to make him turn an even darker shade.
“Where are we?” Alastor demanded instead, holding his hand firmly in place.
“My home. You were going into heat and it seemed prudent to get you somewhere…less public. And safer. How are you feeling?”
“…please don’t make me answer that. I’m struggling enough as it is. My suppressants…”
“Failed. Did you get them from a different supplier this time?”
He gave a slow shake of his head. “No, but I trust her. She wouldn’t sell me a subpar product.”
“It’s possible they won’t work for you anymore. It can happen from overuse.”
His eyes went wide at the implication. Four heats a year for the next fifteen years, and he may not be able to rely on suppressants anymore. Alastor’s scent grew bitter with distress and Lucifer’s dragon demanded he soothe him. He leaned down, pressing a kiss to his forehead and earning a startled look for his trouble.
“We can worry about that later. Let’s focus on what’s happening now. I don’t think I can leave you alone. We’ve spent too much time together. You’ll just go looking for me.”
“I would not! I’m not some desperate, pathetic Omega!”
Lucifer arched a brow. “My hand is literally in your—“
“Don’t you dare say it!” he hissed, his flush spreading down his throat.
“All right, all right, I won’t. But while you’re mostly in your right mind, I need to know how far you want this to go.”
“How…far?”
“We’re going to be together for the next few days. I’d like to know if there’s anything you don’t want me to do. Like actually knot you.”
Alastor sank his teeth into his bottom lip before hazarding. “Does it…feel the same?”
“Not quite, at least from what I’ve heard. It could make your heat last longer though, if I don’t.”
“I know that! I may be inexperienced, but I’m not an idiot.”
“I didn’t say you were.”
He shoved his glasses up so he could pinch the bride of his nose. “Fuck… I can’t take more than a few days off of work…”
Not without rousing suspicion, especially if he started having regular heats. Even if the university was willing to let him keep his position, there would be an uproar over an Omega teaching there, let alone an unmated one. Most would say it wasn’t an Omega’s place to educate Alphas and Betas. Not to mention the accusations he was trying to ensnare one of his wealthy students.
The university would cut its losses, rather than be tied to a young, loose Omega. Not to mention there was the distinct possibility someone would try to take advantage of Alastor if they knew too. People had been blackmailed with far less.
Lucifer’s dragon insisted none of that would matter if they were mated. If his own status wasn’t enough to pave the way, he had plenty of money to throw at the problem. Of course said dragon was far more interested in locking Alastor in his hoard where no one else could see or touch him.
It very unhelpfully suggested a series of tantalizing scenarios. His Omega, blissed out and cuddled in his arms, his knot joining them together. His Omega dripping in jewels and tied to his bed, begging to be filled. His Omega, heavily pregnant, waiting for him when he came home and allowing Lucifer to dote on him and their soon-to-be pup.
Granted, the last was the least likely scenario. Pregnancy by dragon was a rare and precious thing. It was practically unheard of if the Omega in question wasn’t their soulmate. Despite his many centuries (and many attempts), Lucifer had only been blessed with his little girl.
Alastor was doubly lucky he was the one who found him. With the ongoing concern about low birth rates across humans too, contraception was as difficult to find as heat suppressants without a legitimate medical reason and prescription. His chances wouldn’t have been high regardless, but they were as good as nonexistent with Lucifer.
The Omega set his glasses to rights and self-consciously lowered his hand to his mate gland, fingers stilling when they came into contact with the jewels there. “Did you fucking collar me?” he demanded.
“Would you rather I have marked you? I only have so much control and you baring your throat was threatening to destroy it.”
His eyes went wide as his darkest flush yet filled his cheeks. “…oh my fucking gods…”
“Which is the main reason I suggest you stay here with me, rather than try to go off and handle this on your own. Otherwise you’ll wind up on the registry at best, or mated to a random Alpha at worst.”
There was a very long pause before Alastor offered a quiet, “Thank you.”
“You’re welcome, treasure.”
His expression grew pained. “Do you have to call me that?“
“I consider it a small concession in exchange for everything else.”
He huffed but let the matter drop. “…fine. You can knot me.”
Lucifer knew his dragon flashed in his eyes then, accompanied by a burst of Alpha pheromones that had the Omega baring his throat all over again.
The instant Alastor realized what he was doing, his shoulders crept up toward his ears. “…fucking hells… Is it always like this?!”
“It’s probably more intense for you because it’s your first and only. I imagine your Omega has been very vocal about it all.”
He glanced away, clearing his throat. “…how much will I owe you after all of this?”
“Owe me?”
“For…services rendered.”
Lucifer considered the question a moment before shaking his head. “Let’s discuss that when you’re not in the midst of your heat.”
There was a stubborn set to the Omega’s jaw, but his righteous indignation was already fading as the next wave of his heat approached. Lucifer gingerly pulled his hand free, relishing the plaintive whine Alastor gave on finding himself empty.
“Y-You’re not leaving are you?” he blurted, not quite hiding the panic in his tone.
“No, just giving you what you need instead,” Lucifer said as he lined himself up.
He swallowed hard as he began to tense again, so Lucifer pressed his face to the collar just over his mating gland. It was like hitting a switch for the poor thing’s instincts to run amok.
“Alpha! Alpha, please!”
How could he deny such a pretty request?
Lucifer began to press into him, groaning as his straining cock sank into his tight, wet heat.
“O-Oh, fuck!” Alastor hissed, spreading his legs wider as he quivered with need. A relieved sob escaped him when Lucifer fully sheathed himself, easing his building distress and quieting his screaming instincts.
“You all right?” he asked, giving him a moment to adjust.
He tentatively met his gaze as he hazarded, “…that’s all? We’re…knotted?”
If he spent the entirety of his life pretending to be a Beta, Lucifer supposed he hadn’t gotten the best sex education. Admittedly the Omega was also struggling to keep a clear head.
“Not yet,” he said as he gave a slow roll of his hips, making him gasp.
He gradually increased his pace, trying to be mindful of his inexperience. Regardless of the circumstances that brought them together, Lucifer wanted him to enjoy his deflowering.
The Omega’s legs wrapped around his waist in return, blunt nails scrabbling against Lucifer’s back and shoulders in an attempt to draw him even deeper.
Lucifer smirked as he slipped his hand between them to rub firm circles against his clit. Alastor’s breathing quickened, his walls reflexively tightening around him.
“O-Oh!”
“It’ll feel even better in a second,” he said, pressing a kiss to his temple.
The puzzled, incredulous look that got him was precious.
The base of his knot was already beginning to swell, but Lucifer didn’t immediately push it in. Instead he waited until the Omega was grinding against him with increasing urgency before he eased it inside of him as gently as he could.
Alastor’s nails dug deep enough into his shoulders to draw blood as he came with a sharp cry.
That was all Lucifer needed to push him over the edge too, and he came while Alastor’s walls were still fluttering around him. His dragon rumbled in pleasure at the completion of a successful mating.
As badly as he wanted to collapse onto the Omega and properly scent him, Lucifer forced himself to lean back enough to give him a once over. His hazel eyes were hazy, and he’d gone boneless beneath him.
“You did very well, treasure,” he murmured, stroking his sweat damp hair from his eyes,
His eyelids fell to half mast as he gave low, pleased purr in answer. An Omega purr.
Lucifer’s mind went fuzzy around the edges as a deep sense of peace and tranquility settled over him. His dragon rumbled again in answer.
Mate. Mine.
His fingers trailed down to the collar protecting Alastor’s mate gland, and the Omega shivered as they brushed over it. He could banish it and properly claim him. It’d solve a good deal of Alastor’s problems. He wouldn’t have to worry about hiding anymore, and Lucifer would always be there to help him with his heats as his mate.
The Omega clearly didn’t take proper care of himself, judging by how thin he was. Lucifer could ensure he had proper meals, prepared to fill out his tantalizing figure, as well as to bolster his and their pups' health while pregnant.
He could ensure Alastor got proper sleep too, something he clearly struggled with, given the dark circles beneath his eyes. He saw it all so clearly. His mate up late in the library, too focused on his work to stop. Until Lucifer swept in, that is. He’d fuck him senseless over the desk before lifting him into his arms and carrying him to their bed in the hoard.
Although, that was another thing to consider… Should he allow Alastor to keep his job? It was his right as his Alpha to make such decisions for him. The thought of him alone with classrooms full of Alphas and Betas was enough to make smoke curl from his nostrils. Not safe.
All he had to do was banish the collar and take what was his…
A sudden shrill noise, reminiscent of the ring of a house phone, jolted Lucifer from his thoughts. He blinked, lifting his head to locate its source. The lovely purring beneath him stopped, much to his dismay, as Alastor came back to himself too.
“My phone,” he mumbled, clearly struggling to shake off his instincts. Lucifer hated it. He wanted to see him settle fully into them, dammit!
He shifted where he lay atop him, purposefully jostling his knot in the process. Alastor’s eyes went wide as he gasped.
His little Omega was so sensitive. He moved again and Alastor whimpered before managing a choked, “A-Alpha!”
“I’m right here,” he insisted, running his fingers through his hair to soothe him.
Those pretty hazel eyes went unfocused, his face flushing as he sank his teeth into his bottom lip. He might’ve fully settled back down if his blasted phone hadn’t continued ringing.
Lucifer summoned the device with his magic, scowling down at it. Alastor wrestled his Omega back, brow pinched in concentration as he held his hand out for his phone. Though he wanted nothing more than to turn it to ash, he relinquished it instead.
Alastor squinted at the screen before answering it, to Lucifer’s surprise. “Vincent?” he prompted, clearing his throat when it came out more like a croak.
Though he kept it to his ear, Lucifer easilt heard every word with his heightened senses.
“Hey, Al! You doing all right? I know you said you were going out of town, but you never got back to me.”
“Oh! Sorry about that. I got… I was… Er… Everything’s fine! Just got a little…sidetracked.”
“Are you sure? You looked kind of rough earlier."
“I’m sure! How’s Valentino?”
Lucifer arched a brow and the Omega had the audacity to lift his hand to shield himself from his disbelieving gaze.
“Good. Dunno who’s more excited his due date’s coming up, me or him. Vel’s been pretty vocal about getting to dress the baby up. She’s been working on new outfits ever since she found out she’s gonna be a big sister.”
A small, genuine smile came to Alastor’s face at that, making Lucifer’s heart swell in his chest. “I bet she has.”
Another voice sounded in the background of the call in a mix of English and Spanish. With only a rusty grasp of the latter, Lucifer struggled to puzzle the words out.
“Papa, daddy’s saying bad words in Spanish! He’s gotta give me quarters!” a young, female voice interjected.
Alastor chuckled. “You’d better go take care of your Omega before he takes care of you. Oh! Do you still need me to babysit next weekend?”
Vincent gave a heavy sigh. “Yeah, if you’re still up for it. You’re the only babysitter Vel’ll tolerate.”
“Is that uncle Al?! Hi, Uncle Al!”
The Spanish grew both louder and faster.
“Shi… Gotta go! Let me know you get there okay!” Vincent said before abruptly hanging up.
Lucifer plucked the phone from Alastor’s lax grip, earning a squawk of protest.
“Hey!”
“Call’s over,” he said, tossing it out of reach across the bed.
That earned him an annoyed scowl. “What else do you expect me to do while waiting for your knot to—“
He swallowed the rest of what he intended to say when Lucifer gave a small rock of his hips.
“Sorry, I didn’t catch that,” he replied, grinding harder into him and brushing against his clit in the process.
The Omega gave one of the most pitiful whimpers he’d ever heard. It immediately became Lucifer’s new mission in life to hear it again.
“Hmm?” he murmured, repeating the gesture.
He got a high pitched whine that time as Alastor arched under him. Lucifer smirked as he lowered his head to brush his tongue across one of his nipples, squeezing the other between his fingers.
“A-Alpha!” he pleaded, trembling with need.
Just in time for his knot to finally slip free.
Lucifer’s smirk widened as he flipped the other man onto his stomach and hiked up his hips before rocking back into him. Alastor fisted the sheets in both hands as he spread his legs further, desperately trying to meet him thrust for thrust.
Watching the eloquent and put together Omega shatter to pieces on his cock was intoxicating. So proud and independent until he fell prey to his biology and his baser urges.
Alastor buried his face in the mattress as he began to tense. Lucifer’s dragon resurfaced and he ran the tips of his claws along the Omega collar. Not to destroy it but rather to warp the metal, allowing him access to his mate gland but not enough to actually claim him.
Lucifer’s body expanded in size as more of his dragon nature crept in. He was tall enough now to drape himself over the Omega’s back, lowering his head to nuzzle the bared patch of skin before dragging the tip of a fang along it. Alastor shuddered hard, body seizing as he came again with a wail that was too loud to be entirely muffled by the blankets.
Lucifer wasn’t done yet though. He continued to nose at his gland, thoughts growing hazier as he became drunk off of the Omega’s pheromones and his dragon’s desire for him. He pressed his lips to what he could reach in searing, sucking kisses while Alastor writhed beneath him, sobbing from overstimulation even as he brokenly begged for more.
He nipped hard enough at the spot that he could taste the unique mix of ripe strawberries and peat that was distinctly Alastor on his tongue. He gasped, obediently turning his head to the side and baring his throat like the good little Omega he was. Before Lucifer could stop it, his dragon wrested control from him, sinking his fangs into what rightfully belonged to him.
