Sebastian knew that the new fifth year would always be better than him in perhaps almost everything she did. The better dueller. The stronger wizard. The kinder soul.

He supposed it was only natural. After all, she was the first witch in centuries that could wield an ancient, extremely powerful form of magic. So of course she'd always be better than him, no matter how hard he tried to catch up.

He didn't mind, really, not when her shine was so mesmerizing. It wasn't like his fire, which could be too volatile and brash. Could swallow an entire forest if left unchecked. Hers was just right. Like the sun.

The first time he had seen the little witch so helpless and vulnerable was when her heat came shortly after her seventeenth birthday. Hogwarts had always been careful to protect students who experienced their first heat or rut, and there was a specialized room next to the hospital wing to care for them.

Sebastian had been there once, so he knew where it was. He also knew that the best choice would be to leave her in the care of Nurse Blainey. It was logical. It was the right thing to do.

He went to see her anyway. It was in his nature, after all, to go against the rules. So he flew to the hospital wing and knocked on the window with Honeydukes sweets secured in his hands.

The window opened and the girl of his dreams emerged. Like an apparition. A moon goddess that emerged from the dark.

Her cheeks were flushed in the most tempting shade of red. Beads of sweat adorned her face like pearls. Her hair was a mess, sticking to her forehead and exposed neck, making his fingers itch to smooth them. White, flowy nightdress clung loosely on her wet skin, its neckline had slipped dangerously over one shoulder.

But her scent.

Goodness, her scent.

It was like he was being drowned in a sea of mallowsweet and cedar. So sweet and refreshing, he felt like he was running along the meadows of Feldcroft. He couldn't get enough of it. Jumping over the window to claim her had never been a better idea.

“Sebastian…” she called out breathlessly, his name rolling sweetly on her pink lips.

She looked at him like he was everything she could ever dreamed of. Like he was the manifestation of her deepest, most desperate wish.

“Yes,” he rasped, hovering closer like a moth entranced by light. He couldn't stop looking at her neck, at the exposed scent gland, at the top of her breasts. “Yes, sweet girl?”

“You… you came.”

She spoke as if he brought her deliverance and Sebastian held on to it like she was his lifeline. Had she been waiting for her? Was he the one he desired as her heat came? Recklessly, he flew closer to the window, hand stretched out, ready to hold her, emboldened by her treacherous whimper. Anticipating.

Only for him to be stopped by some sort of invisible barrier, preventing him from actually entering the room.

She let out a sigh. “Please…” the girl begged, whether for him to leave or to blast the damn enchantment away, he didn't know.

He whispered her name in veneration. Freckled hand carefully tracing the outline of her face from the barrier, wondering what her skin would feel like under his touch. Would she savor it? Would she beg for more? He hoped she would. Perhaps she would, judging by the way her eyes darkened in hunger.

“What do you need?” he asked again, persistent, eager to give whatever it was she sought.

Swallowing back a whimper, she moved one of her hands down her body, brushing against an erect nipple, down and down to a spot obscured by the windowsill. But he didn’t miss the rustling of her nightdress, the way a portion of the fabric started to bunch up under her chest. He didn’t miss the languid movement of her hand nor the way her eyes rolled back, teeth sinking into her bottom lip as she let out the softest moan.

“Please…” she pleaded again.

The groan he let out was almost pained. Desperate. He almost, almost blasted the entire wall open, had already held his wand tight to conjure the spell, yet the sound of jangling keys and the door being unlocked broke him out of his trance. The damned nurse was probably checking in on her. Quickly, he retracted his hand and steadied his hold on his broom. She let out another whimper, mourning the touch she did not even feel.

“I'll see you once it's over,” he whispered.

He flew away before the nurse could spot him.

That night, he didn’t sleep. Instead, he pleasured himself to the thought of fucking her and he came with the thought of his teeth sinking into the skin of her neck, claiming her as his own.

six years later

Bright lights were flashing around him. Red and green. They burst out of wooden wands each time an adrenaline-fueled incantation or curse was chanted. The scent of wood and smoke was thick in the air. Yet even then, even amidst all the cacophony, he could still pick up a faint note of mallowsweet. Earth persevering amidst destruction.

She stood bravely beside him, taking down their foes one by one with a gracefulness that was almost distracting. Sebastian Sallow knew he should focus, but at that moment he didn't know what excited him more, the heat of the battle or how beautiful she looked when she was being deadly.

“Confringo!”

Her voice echoed loudly throughout the clearing. A bright red light sparked from the tip of the wand, blasting the last Ashwinder right on their chest. The force shoved the poor bastard back, spine hitting the tree with a terrifying crack. If the Blasting curse did not kill them, that impact would. He couldn't help but grin at that. Triumph and satisfaction blooming in his chest knowing that she was still very much fond of the curse he taught her all those years ago in the dimness of the Undercroft.

For a moment there was no other sound save for their heavy breathing. Eyes carefully assessing the pile of dead bodies around them. At last, she moved, straightening her back with a sigh.

“Well, glad that was over.”

Sebastian smirked when their eyes met. “Nice spell. Very fiery. Wonder who taught you that?”

The girl averted her gaze as she bit back her smile, twirling her white wand in her hand. He resisted the urge to pinch her cheek.

“Mm, an old friend. He taught me when we were still young.”

“An old friend, hm? Well, this… old friend must’ve been a very strong wizard, knowing such a powerful spell at a young age.”

She looked up at him and laughed. “I suppose he was quite strong. I beat him on a duel on our very first meeting, though.”

This time, Sebastian laughed along, shaking his head. “Was hoping you’d forget that.”

“What, you don’t think I’d be so cruel as to forget how we first met, do you?”

“Heh. No, I suppose not. It must’ve been such a precious memory to you, no?”

“And now you’re putting words in my mouth,” the witch shook her head, though the playful smile still lingered on her lips. Softer, this time. But then she cleared her throat and stared at the mess around them. “Even in the remote corners of Wales, we still encounter Ashwinders.”

He supposed it wasn't too odd, considering how big of an organization the Ashwinders are and how little the ministry did to stop them. But at the same time, he'd appreciate a bit of variation, especially when he had never been to Wales before. Gringotts had tasked the two of them to retrieve and break the curse of a valuable artifact that was said to belong to a powerful wizard. His research led him to the northern region of Wales, in a dense forest where the wizard's castle was rumored to be located.

“I know. Boring, isn't it?” He replied as he inspected one of the dead bodies.

Sebastian expected another witty remark or perhaps a complaint. Yet her response made his head turn.

“...Damn it.”

There was an unexpected heat in her voice, a stark contrast to her jest just a few seconds ago, and it took him by surprise.

“What is it? Are you hurt?”

She did not seem to be. At least, from a glance. There were a few smudges on her cheek and some strands of hair had escaped her long braids. But otherwise, she was as radiant as ever. Not that he would ever admit it.

The witch showed him a torn bag. Hers. He could see shards of glass stuck to the fabric and some kind of a blue liquid was dripping from the torn hole.

“Shit. I suppose Reparo can't fix that.”

“Technically it can but…” she let out an exasperated sigh. “Most of the potion has been spilled to God knows where.”

There it was again, the agitation in her voice, now accompanied by tension around her shoulders. Sebastian frowned.

“Is the potion valuable?”

Their eyes met, hers was filled with dread and vulnerability that instantly set off an alarm in him. He did not miss the way her fingers picked at the collar on her neck, hidden underneath the thick fabric of her coat.

“It… it was my suppressant.”

“...Oh.”

The image came before he could stop it. The intoxicating scent of mallowsweet and cedar tree. Her, possibly touching herself right in front of him. Pleading like she had never wanted anything more in this world than him.

He swallowed. Shook his head.

“Oh. Oh, shit. When was— are you—”

The witch seemed to shrink before him, and if it were any other situation, he would've laughed. Would've teased her until she snapped. Occurrences where she needed his help were awfully rare. He supposed if he also could wield a very ancient and powerful form of magic, he'd hardly ever need help from anyone else. Perhaps he'd be arrogant about it too, for who could touch him when he was so powerful?

Yet now, she was looking at him in panic and, his heart dropped when he realized this, in fear. There was fear in her eyes. The last time that emotion was caused by, or directed at him was almost ten years ago, in an ancient, dusty catacomb, after he took his uncle's life.

In a split second, he was swept by an overwhelming need to protect and soothe.

“I've already taken a dose this morning but… my heat… it should be coming—”

“We must Apparate. We need to get you back to the city now and find more suppressants.”

“Can we?” she asked in a small, yet panicked voice. “I can sense magic surrounding us, Seb. Surrounding the entire forest. If it's an Apparition-preventing magic—”

“Well, we won't know that unless we try,” Sebastian replied, offering his hand to her. “Come on. We should try it first and if we can't… Well, let's hope we can.”

Gingerly, she placed her hand in his. It was cold and clammy. Sebastian didn't hesitate to give it a reassuring squeeze.

“It's going to be alright.”

“Okay.”

Squeezing his eyes shut, Sebastian pictured the small town they had left three days ago, and he thought of it hard . Yet, just as she had predicted, nothing happened — not even a sliver of wind. Their feet stayed rooted to the ground. He could almost feel her panic bubbling in his chest.

“Seb—”

“We're going to try again.”

He tried again for the second time. And the third. By the fourth failed attempt, he had accepted that there was no way they could Apparate out of the forest.

“Well, we could make the trek back… or perhaps we could look for the castle. We've been exploring these woods for quite some time, the castle is bound to be nearby. Who knows, maybe we can find some ingredients for your suppressant along the way.”

“We don't have time for back-and-forth trips,” she shook her head. “Let's just find the castle. The sooner we finish this task, the better.”

“Hey,” he called out to her. “It will be alright. I promise I will do everything I can to find that artifact as soon as possible and get you back to safety.”

Her eyes widened for a moment, rosy lips hanging open in a way that mesmerized him.

“Thank you, Sebastian.”

He grinned, feeling his soul coming alive at the expression of gratitude. Almost bashful, he nodded.

“I'll keep you safe.”

By nightfall, they still couldn't find the wizard's castle and his companion was visibly upset. She sat quietly before the campfire he had set up, unmoving as if someone had petrified her, while he cooked them dinner. Sighing, he approached her with a bowl of warm soup.

“You should eat.”

She looked startled, as if it took a while for her to notice his presence. The witch shook her head.

“I don't think I can…”

“Stress would only make your heat come faster. You need to take care of yourself,” he said, trying to be as gentle as he could. “You're going to need energy if you want to find the wizard's castle.”

There was a brief silence before she finally relented and carefully took the soup from his hand. He took a step back but kept his gaze on her, watching as she began to eat.

“It's very good.”

Sebastian smiled. “I'm always the better cook between the two of us.”

The little witch rolled her eyes, smiling for the first time that day. “No need to rub it in my face.”

“But at least that made you smile, didn't it?”

She dipped her head, though the smile still lingered on her lips. Sebastian half-expected a rebuttal, a snarky comment, yet it didn't come. No doubt she was still too worried about her unexpected predicament. Naturally.

He was about to turn back and help himself to a serving of soup before she spoke again.

“Have you ever spent it alone?”

When he gave her a quizzical look, she continued.

“Your… rut. Have you ever spent it alone without any suppressants?”

Sebastian stilled. “Yeah, I have. It was a while ago. Remember my solo mission in Romania?”

“It was during that time?” she asked in surprise.

“Well, yeah, I wouldn't have much difficulty getting a suppressant if I was in the comfort of my home,” he chuckled. “I won't sugarcoat it. It's terrible. Don't ever want to experience it again, though I think it was basically a rite of passage for everyone. You gotta experience it at least once in your life.”

He could almost recall the painful desire that tormented his entire body. As a Curse Breaker, he was no stranger to getting wounded or hurt during his mission, whether from his enemies or from a cursed object. Yet the pain he felt during his rut — how his entire veins felt like they were filled with fire, how no amount of touching would relieve the desire in his body — was unlike anything he had ever experienced.

And during that hellish period, all he could think of was her. Her smell. How absolutely tempting she looked during her first-ever heat. How good would it feel to claim her, fuck her until she forgot everything but him, fill her up to the brim until she’s with his—

Sebastian shook his head. His mind was wandering. It was already bad enough that she showed fear around him, he didn't need to give her more reason to be afraid.

“That sounds like hell,” the woman spoke, blissfully unaware of the treacherous thoughts in his mind. “I don't want to experience that.”

His expression softened. He longed to caress her hair and chase away her fears. He could protect her.

“We’ll find a way,” Sebastian promised. He didn't know how he was going to fulfill it, but he knew he'd do anything to make her feel safe. “You should get some rest. With your suppressants gone, you’re going to feel some effects in the morning.”

She let out a heavy sigh, shoulders sagging.

“Alright. Good night, Sebastian.”

She cleaned her empty bowl with magic before retreating to her own tent. He didn't miss her whispering a spell as soon as she got inside, nor the new protective barrier that soon enveloped her tent.

Sebastian bit the inside of his cheek. Her caution was warranted, he tried to tell himself, all omegas should be very careful around alphas. But he supposed this also meant that, even after all these years, she still had some reservations about him. That realization made him want to jump off the nearest cliff.

By some sheer, dumb luck, they managed to find the castle the following day, just sometime before sundown. It was hidden in the jagged, towering cliffs that surrounded them and, unfortunately, in a much worse condition than they expected. A good portion, if not all of it, was in ruins, with little walls to shield them from the cold and wind. Not that it mattered, really, not when they had their own tents and all. Yet he was hoping he could find something useful for her in a place that was supposed to belong to a powerful wizard.

The girl slumped on the grass beside him, the effects of her coming heat and the missing dose of her suppressants had begun to take a toll on her body. She was exhausted, her breathing was ragged, eyes unfocused as she stared at the ruins before her.

“There's a path that leads underground… maybe that's where he kept the artifact,” she said, somehow still thinking about their mission despite her deteriorating body.

Sebastian, on the other hand, could not give a damn about the object at the moment. He knelt down beside the girl to check on her, careful not to touch or aggravate her even more.

“We can think about that later. For now, you need a place to rest. There’s one room over there, still functional, but we can use your tent if you want.”

She tilted her head to look at him but made no effort to reply. It didn’t even seem like she was paying attention to what he said. Her pupils were dilated, cheeks all flushed, whether from overexertion or something else, Sebastian didn’t know. Didn't dare to guess. Their close proximity made it so much easier for him to smell her dangerously sweet scent.

Her lips parted open.

“Sebastian…”

That had got to be the famous siren call that drowned ships and lured sailor to their deaths, he was sure of it.

“What is it? What do you need of me?”

“I don’t feel too good,” she admitted softly, her body swaying sluggishly as if it was a struggle to sit upright.

“I know,” he replied. “I know, that’s why we need to—”

Words died in his mouth when she leaned close and buried her face in his shoulder. Immediately, he froze. The witch, however, did not seem to notice his reaction. Instead, she took a slow, deep breath and let out a pleased hum.

“You smell so good, Sebastian,” she murmured, visibly relaxing. “So comforting.”

He inhaled sharply, muscles tensing as he mustered all the self-preservation he had to keep himself rooted to the ground and not pounce on her.

“...Am I?” he asked anyway, tempting both the devil and himself.

This time, her small hands had curled around his arm. “Mm, very much so. You smell like pine trees and caramel… I like it.”

A shiver ran down his spine and his fingers twitched, desperate to hold her, but he closed his eyes tightly. Not like this, he thought. You wouldn’t want it to be like this. She doesn’t really want you.

As careful as he could, he held her hands, relishing how warm they were against his own, how small. She looked up at him expectantly, wondering what he would do. But he placed them on her lap.

“Listen to what I’m telling you,” he said, gently squeezing her hands before letting them go. “Your heat is coming. I need… you need to find somewhere safe to hide unless… before any of us do something we might regret.”

The hurt that flickered in her eyes surprised him and his instincts immediately told him to comfort her. But you couldn’t, you mustn’t, Sebastian reminded himself, willing himself to stay still.

“Oh,” she responded and — he thanked all the gods above — finally withdrew, putting more distance between them. “I…” she blinked rapidly, stammering. “I’m sorry. I didn’t mean to—”

“It’s alright. It’s something you had no control over, don’t apologize. Let's get you comfortable, yeah?”

Her eyebrows furrowed as if she took offense to his words. But then she sighed and nodded in defeat.

“Alright.”

Carefully, he led her to the only room in the castle that was still fully intact. Every surface was covered in dust, but he quickly cast Scourgify to clean the entire space. He tried to fluff the bed and pillows as best as he could and fortified the room with protection charms. No matter what, she needed to be safe and comfortable.

“I think you're going to need more pillows and blankets… you have more in your tent, right?”

He looked at her, expecting a response, but the girl only stared at the bed he just made, lips caught between her teeth. When he called her name, her gaze shifted towards him.

“Yes. Yes, I have more.”

“Good. I need to check the area, make sure everything's safe, see if there's something we can use to alleviate your pain. I'll come back to you in a bit, alright?”

“You're leaving me?” the words left her mouth before she could stop it and her cheeks immediately reddened. “I'm sorry, I've troubled you enough, please forget I ever said that.”

He would rather die than forget it, actually. Those words might not come from her heart, perhaps she would never have said that if she weren't in heat. But he cherished it all the same.

“Only for a short time. I'll come back as soon as I can.”

She looked at him and Sebastian swore that gaze could bring even the cruelest god to his knees.

“...Promise?”

A lump formed in his throat. “I swear on my life.”

She was fast asleep when he returned to her chamber with a warm meal and pain-relieving potions he just brewed. The bed now resembled a proper nest, with pillows and blankets stacked on top of one another. She was laying in the middle, still fully clothed, much to his relief.

However, as soon as he was close enough to the bed, the girl was roused from her sleep, long hair falling down her shoulders like she was an elf from myths. She blinked drowsily at first before her eyes found him and relief flooded her.

“You're here.”

He smiled. “I made a promise, didn't I?”

Her face lit up adorably. “You did.”

Sebastian cleared his throat and averted his gaze, worried that if he looked at her a second longer, his resolve would crumble.

“Dinner's ready,” he spoke, setting the meal and potions on the bedside table. “And I managed to find some herbs. They won't substitute for a suppressant, unfortunately, but they’re especially useful for pain-relieving potions. Should help a bit.”

“I've troubled you so much,” she muttered sadly. “I'm sorry. I should've been more careful.”

“What? What are you— none of this was your fault! It was an accident!” he blurted, perplexed.

“But I—”

“No, you're not blaming yourself. You—” Sebastian stopped himself. Took a deep breath before sitting at the edge of the bed and holding one of her hands, the only contact he allowed himself. “How many years have we known each other, hm?”

“...Almost ten, I believe.”

“Mhm, and did you remember how much trouble I've been causing you? Troubles we got into? Remember our fifth year? You had been so… I was…” Sebastian stammered, words abandoning his mouth as he struggled to speak without laying all his feelings bare.

He took a deep breath and searched for her eyes.

“We've been through so much but we always figured out how to solve it in the end, haven't we?” he said in a soft voice, gently rubbing the back of her hand with his thumb. “We'll figure this one out, too, yeah?”

The girl could only nod as she stared at their hands. There was some sort of longing in her gaze. A fervent kind of yearning. But perhaps it was his eyes playing tricks on him.

“...Okay.”

There was a brief silence as she ate her dinner and Sebastian decided to use this chance to double-check the room, making sure that every door and windows were protected with magic so that nobody could break in.

“Sebastian,” she called again.

“Yes?”

As soon as their eyes met, she averted her gaze, cheeks reddening in embarrassment. “I, um…”

He returned to her side, giving her his full attention. “What is it, angel? What do you need from me?” He softly asked, the nickname slipping out before he could stop himself.

The girl dipped her head, further avoiding his eyes. “Promise me you won't be disgusted with me…”

“I'd never be disgusted with you!” He quickly said, frowning at her outlandish request. “Tell me what you need, I promise I won't be angry or grossed out.”

Timidly, she looked up at him. “Your coat…” she quietly said. “Can I borrow your coat for a bit? I know this sounds incredulous, but the nest—”

Without even waiting for her to finish, Sebastian took off his wool coat and wrapped it around her frame. Perhaps he shouldn't have indulged her, perhaps it would've been wiser if he kept his distance, but this time, his desire overpowered him. Emboldened by the revelation that it was his scent she sought, his clothing she'd like to keep in her precious nest, his presence that gave her comfort. Even if she only said that because she was in her heat, Sebastian didn't care. He'd take even the smallest sliver of affection she'd give him and guard it like it was the world's most valuable treasure.

“It’s yours,” he said, surprised that he didn't even stammer. “Use it however you like.”

She looked at him with wide eyes, rosy lips parted open. Gingerly, she ran her fingers along the edges of his coat before she finally succumbed to her desires and hugged it tight around her body. She nuzzled her face into the neckline and took a long, deep breath.

If he took her right there and then she wouldn't resist, he knew.

But it was her omega speaking, right? Not herself.

Sebastian could feel his mouth running dry when she glanced at him through her long eyelashes.

“Thank you,” she murmured. “I'm so sorry, Sebastian, I—”

“Don't,” he cut her off. “Don't ever apologize. Whatever it is you need from me… I'll give it to you.”

He didn't care if he sounded pathetic. Didn't care if it seemed like he was groveling at her feet. Because Sebastian meant it. He'd give everything to her — the shirt off his back, his soul, his devotion. Anything as long as she's happy and safe.

His soft declaration was met with a pair of eyes that darkened with hunger. She inhaled sharply.

“That is a dangerous thing to say, Sebastian,” she said in a low voice.

“I just—”

“I'm tired,” she huffed. “I've troubled you enough for the day. I'll be going to sleep now.”

“Right,” he said despite the lump in his throat. “I'll… I'll be outside.”

The girl didn't respond and, instead, laid back on the bed. He took consolation in the fact that she covered almost her entire body in his coat. A voice in the back of his mind told him to lay by her side and soothe her. Be a good alpha for the omega. But he strengthened his resolve and walked out of the room.

Sebastian did not sleep a wink that night. Did not allow himself to. He sat a few feet from her room, eyes staring straight at the door, where the air around it seemed to ripple and glow from his protection charms. He might not be her mate, perhaps would never be, but he'd guard her and that room with his life. He'd sooner die than let anything happen to her.

Hours passed by sooner than he realized and, suddenly, the faintest shade of red began to peek from the eastern sky. The rising sun.

Then, he could hear her.

He couldn't smell her. His charms made it impossible for her scent to seep out. But they didn't block her voice or any noises that he made.

And he heard her.

It sounded so soft that he thought he imagined it at first. But he could hear the small gasps that escaped her lips, gasps that soon turned into faint moans. Her heat had definitely arrived and his treacherous mind longed to see her. What would she look like right now? Is she touching herself to his scent, nose buried in his coat? Does she think of him as she seeks relief and pleasure?

He gritted his teeth and slammed the back of his head against the stone wall.

No, he told himself, pushing down baser urges that had surfaced from within him. Not now.

Yet her delicate voice continued to echo throughout the empty ruins and Sebastian wondered if he should cast Muffliato on her, but before he could even consider that option, her voice grew louder, rising an octave higher, like a strangled cry.

“Sebastian…”

He was right in front of the door in an instant, as if she pulled him with Accio. His hand instinctively reached out to the doorknob, yet the invisible barrier prevented him from even touching the metal surface of the object. Sebastian almost groaned, a thought to blow the door open came to mind, but he couldn't. He shouldn't.

She called out to him again and his heart broke.

“I'm here, sweet girl, I'm here.”

He could hear a wet sob. “It's hot… it's hot everywhere…”

“I know, I know, angel,” he responded, forcing himself to keep his mind clear even though other thoughts were threatening to take over. “I know you're hurting all over, doll, but there are some potions on your bedside table. Can you try drinking them for me?”

“I don't want them, I want you!”

A lump formed in his thought. In an instant, a voice rang in his ears.

Take her. Take the omega. She's offered herself so sweetly to you! Claim her! Bite her! Breed—

Sebastian bit his tongue so hard it drew blood. But the pain forced some clarity back into his intoxicated mind. There was a reason why he needed to protect her. If he followed his primal urges and claimed her, only for her to regret everything and scorn him after her heat subsided, he'd have nothing left in this world. He'd lost his parents. Lost his twin. He'd rather die than lose her too.

“We can't,” Sebastian replied, perhaps more to himself than to her. “...Drink the potion, sweetheart, please, it'll help. I promise.”

He could hear a shuffling from inside the room, like something heavy was being dragged across the floor. He could hear her gasping and sobbing. When she spoke again, her voice was much louder.

“Why can't we? Why won't you?”

She was right behind the door, he realized. His hand moved towards the barrier once again, pressing against it as if he had done it hard enough, he could feel her.

“Seb, please…” she pleaded again. “Please, please, let me out… it hurts so much. I won't regret this, I promise—”

“We can't! You don't! You don't know what you're talking about!”

Sebastian covered his ears with his hands, desperate to block all the noises that were clawing at his self-control. Yet it was useless. He could still hear her cry and that vicious, greedy, insatiable voice inside his head, now mocking him.

Foolish alpha. Useless alpha, letting your omega suffer!

He bit his tongue again. Blood filled his mouth. Not mine, he told himself over and over again like a mantra. Not mine, not mine, never mine!

But the desperate omega paid no heed to his warning and his rejection had only stroked her ire.

“I know what I'm talking about, it's you who don't!” she finally screamed, banging her fist against the door until the wood rattled and creaked.

Sebastian’s eyes snapped up, wincing when he could hear how labored her breathing sounded. The sudden burst of energy must have taken a toll on her body. He opened his mouth to speak, but she beat him to it.

“Wanted you for so… long,” she admitted, her voice weak and thick with tears. “Please, Seb… I—” a pained cry. “I yearn for you… before the heat and… I’d still— still yearn for you after. Please… Please…”

The weight of her confession hit him in full force, rendering him speechless as he tried to process everything she had just said. He was short of breath, exhilarated, and all too eager to grasp this new revelation. This, for him, was a dream come true. But it didn’t take long before his insecurities sank their claws back at him, spreading chills all over his body.

“M- me?” he stammered. “But I…”

There was a darkness in his heart that consumed everything and everyone around him. Misfortune had been following his steps like a curse. He thought of the girl on the other side of the door. All his life, Sebastian had been stubborn. His steadfastness had been both his strength and vice. What he wanted, he’d get.

And, god, he wanted her. He wanted her like he wanted magic. She was the purpose that guided his steps, the light that defeated his darkness. How could he not long for her? But he had hurt her before and she'd seen how despicably evil he could be, should his desires and ambitions be left unchecked. If he hurt her again because of his weakness…

If he tainted her with his darkness…

“Come to me…”

Her soft, pleading voice wafted over him. Weak. Wet with tears. Like the siren who longed for the sailor.

“Sebastian, alpha… come to me.”

The rule of the secondary sex was clear: the alpha is the dominant one and the omega submits to the alpha.

But Sebastian, his life and soul, had belonged to the girl ever since she prevented him from going into Azkaban. He was hers and would always be hers. He’d follow her wherever she’d go, staying by her side for as long as she’d allow him.

And she had commanded him to come to her. Alpha, she called, stoking the fire that he had been trying so hard to suppress. Alpha, when he’d do anything and everything she wanted, a dog awaiting its master’s orders.

He picked up his wand and pointed it towards the door.

When all the protective charms had been melted away and the door swung open, he first noticed her scent. Sweet. Potent. Electrifying. It intoxicated his mind without any difficulty, clouding it in a luscious haze. He found her lying down right in front of the door, curled into a fetal position, her naked body covered in nothing but his coat.

Her cheeks were the color of a ripe apple, and her eyes were glassy with tears. But when she looked at him, her face lit up, and a dreamy smile curled on her lips, as if he was her salvation. Languidly, she stretched one arm towards him.

“Sebastian, you came…”

He was on her in an instant. Scooped up her frail body in his arms to return her to her nest. It was then he noticed she had already taken off her collar. He couldn't resist. He pressed his nose against her scent gland and groaned.

“Oh, my sweet, you smell like heaven.”

A soft moan left her lips as she craned her neck, enticing him to touch more of her body.

“I’m here, angel, I’m here. I’ve got you,” Sebastian whispered reverently as he gently placed her on her nest, dragging his lips across her temple. “It’s okay, now. We’ll be okay. You won’t be in pain anymore. Not while I’m here.”

When he pulled away, she chased after him, the tips of their noses brushing against each other.

“Please…” she begged, her breath fanning his lips.

He gazed down at her body, at the way her flush had spread to her chest, full breasts peeking from his coat. Sebastian let out another groan.

“So pretty, so beautiful,” he whispered, running his hands up her thighs, relishing the suppleness of her skin. “All for me, aren't you? All mine?”

“All yours,” she nodded vigorously, still chasing after his lips. “Only you, alpha, please.”

Sebastian cupped her cheek, swiping her thumb along her wet lips. Adoration shined in his eyes as he gazed at her. “I’m yours too, my love, always been yours.”

He claimed her lips in a kiss that was soft, gentle, and pure. She was soft and warm against him, like rose petals brushing against his lips, so pleasing to bite, to lick, to suck on. And oh, the noises that she made. Sweeter than a siren’s song and he made sure to swallow them all.

His hands eagerly explored her body, pressing against the pulse on her neck, squeezing the supple flesh of her breasts, digging his nail into her hips to pull her into his lap. Wet folds brushed against the hardened cock still hidden under his pants and Sebastian hissed. She kissed him deeper, not allowing him to pull away, fingers aggressively unbuttoning his shirt.

Soon, she was lying back on the bed, his body firm and secure on top of hers. He peppered kisses along her neck, nipping at her collarbone. The girl luxuriated in his worship, delighted moans and sighs falling from her lips, egging him on.

“More…” she pleaded, squeezing his shoulders.

“Patience, my love,” he whispered against her skin, hands quickly removing his coat from her body.

Sebastian pulled away, marveling at the sight of her, so pliant and willing under him. He kissed her again as his hands slithered up her torso, kneading her breasts. She moaned in appreciation, arching into his touch, shivering when his thumb brushed over a pert nipple.

“Mine,” he whispered hungrily as he descended down her body, fingers tracing a line down her waist, hips, and thighs. “My lovely little flower.”

Looking at him through half-lidded eyes, the girl spread her legs, presenting herself to him. Underneath his breeches, Sebastian's cock twitches needily.

“Seb…”

“So wet,” he ran his finger across her slit, breath hitching when his digit soon became coated with her slick. “Beautiful.”

Slowly, his index finger slid into her warmth and he groaned, reveling at the way her walls clenched around his fingers. How heavenly would it feel later, when he spread her open with his cock?

“Did you touch yourself while thinking of me?”

The girl keened, crossing one arm over her face to hide her expression. But he used his free hand to pin her hand on the bed.

“Answer me, omega.”

“Yes—” her answer morphed into a moan when he inserted another finger, scissoring her pussy. “Yes, I thought of you!”

The confession made him light-headed. Already, his cock strained against his pants, but Sebastian clung tightly to the remaining bits of lucidity he had. He'd been dreaming about this moment for far too long and he needed to savor it.

Pulling his finger away, he slotted himself between her legs. Nipping, licking, making his way from her thigh up to her mound. Breath hitched when his fingers spread her glistening folds open. She bucked into his touch, eager and impatient, and he wouldn’t dare to deny her what she sought.

A breathless cry made its way out of her throat when his tongue made contact with her pussy. She tasted like ambrosia. He lapped at her nectar like a drunkard relishing his wine. Kitten licks at her clit, languid strokes of his tongue along her folds as if he was trying to enchant a lust spell. And she responded so beautifully.

“Sebastian!” she keened, fingers tugging roughly at his hair, eliciting a satisfied moan and he could feel her drip into his eager mouth. He could die happily like this, he thought, suffocated by her thighs.

He withdrew for a moment and she was so ready to protest, but two fingers soon entered her core, pumping in and out, while his mouth sucked roughly at her clit. Her long, dragged-out moan made his cock twitch, precum already staining his pants, and he unconsciously ground his hips against the bed, chasing the much-needed friction.

“Al– oh— right there…” the girl sobbed, her walls clenching tightly around him.

“I got you, angel,” he whispered. “Show me how pretty you are when you cum.”

With a few strokes of his tongue and a curl of his fingers against that sensitive spot in her pussy, he brought her to the precipice. She pulled his hair hard, thighs almost squishing his face as she came with a broken cry. Sebastian lapped it all up greedily, moaning in satisfaction.

“You taste so sweet for me,” he groaned, pressing kisses to both sides of her thighs. “My sweet, sweet omega.”

He sat up, admiring the girl as she climbed down from her high, gasping for air. She looked absolutely divine. If Aphrodite was real, Sebastian was certain the goddess would be jealous of her beauty. Strong, beautiful omega, the voice in his mind purred. Delicately, he moved away a wild strand of hair from her face, peppering kisses on her forehead, a gentleness that made her yearn for more.

Faintly, he registered the feeling of her fingers on his chest, persistently tugging at the buttons.

“I… wish to see you,” she quietly said.

“As you wish, princess.”

Smirking, he started to strip, taking off his vest, pulling his shirt over his head, luxuriating in the way she looked at him. Hunger and desire burned in her gaze as she unabashedly traced the line of his muscles down to his hips. Finally, he removed his pants and underwear.

“Oh…”

The sound that left her mouth almost resembled a moan and Sebastian let out a chuckle. Bending down, he caged her between his arms, greatly amused at how she did not even spare him a glance, eyes still staring at his cock.

“Is it to your liking, pet?”

“Please,” she begged again, instinctively trying to rub her thighs together and whined when his body prevented her from doing so. “Please, I'm so—”

Sebastian gave her hand a gentle squeeze. “I got you, I promise.”

Calloused fingers trailed down her body and she arched again, desperate to make each touch stay longer on her skin. He spread her legs, the gravity of his reality suddenly intimidated him once again. Still worried that she never meant a single word she said and that she would scorn him once the week was over.

“Sebastian?” the girl called out to him softly.

Brown eyes met hers. He smiled, brushing her cheek with his thumb. “Last chance. Will you regret me tomorrow?”

Her eyebrows furrowed, but when she spoke, her words were filled with conviction. “I won't. Not tomorrow. Not forever.”

And Sebastian allowed himself to hope. To believe. He leaned in, gently claiming her lips, pouring all his love and adoration for her in that one kiss.

“My heart is yours,” he whispered, taking her hand and holding it against his chest, right above his heart. “Have been yours for a long time and will always be yours.”

She stared at him with wide eyes, her rosy lips parting open in awe before they curled into a smile—the happiest he had ever seen. A giggle slipped out of her, and when she gently cupped his cheek, he leaned into her touch, basking in her love. She kissed him again, lovingly, hungrily, desperately.

“Take me,” she whispered.

The command sent shivers down his spine. Sebastian knew he’d do anything in his power to make that happen. Not even death could take him away right now.

“My love,” he whispered, kissing her forehead.

“My heart,” he descended, pressing his lips on her right chest, cherishing every heartbeat.

“My omega,” he journeyed lower, placing the last kiss below her belly, right above her womb.

She kept his gaze on him the entire time. When he aligned himself at her entrance, she spread her legs even wider, blooming open before him. Her lips parted, letting out small gasps as he rubs his cock along her slit, awestruck at the difference in their sizes.

Slowly, he entered her. Wincing when her pussy, despite the slickness and eagerness, still offered resistance. But the warmth. The wetness. Sebastian let out a long, dragged-out moan as he felt himself entering her.

Nothing, not even his wildest dream, could’ve prepared him for how good it would be inside her.

“Oh, fuck,” he cursed. Hissing, as he sank another inch of his cock into her pussy. “That’s it… oh , give yourself to me.”

Underneath him, the girl was staring at their joined body with wide eyes. She looked like she was barely clinging to sanity. Shaky whimpers came out of her parted lips, egging him on, showering him with encouragement. Her voice rose an octave higher as he continued to push his cock into her, bit by bit filling her to the brim until he finally bottomed out.

When Sebastian looked down, he groaned.

“You’re taking me so well. Good girl… good omega.”

The girl could only gasp in response, her body shivering in his arms. Sebastian pulled his cock until it almost left her pussy before pushing back in as deep as he could, closing his eyes when he heard the wet, sticky sound that filled the room and the delirious cry she made.

“You’re so wet for me, pet, so good around me…” he praised her, grunting when her walls clenched around him. “Oh, you’re tightening up, did you like that? Like the way I fill you up? Like how I praised you?”

She couldn’t even form a proper word or sentence. The only form of response she could manage was incorrigible noises and whines, too overwhelmed by the sensation of his cock slowly going in and out of her. The realization made pride swell in his chest.

“Like it so much you can’t even speak, huh? My cute little omega… so— eager for me.”

Another moan, needy and airy in his ears. He picked up his pace, fucking her in quick, short thrusts. The girl clung to him desperately, nails digging into his shoulders as he suckled her breast. Faintly, he imagined milk coming out of the pert bud once she’s with his child.

His cock throbbed at the thought. Sebastian knew he was a goner.

Their movements soon became more aggressive as she eagerly rolled her hips to meet his thrusts. He let go of her nipple with an obscene ‘pop’, before licking a long strip along her jaw. More slick gushed out of her stuffed pussy, staining their thighs.

“Look at you dripping on my cock,” he wickedly said, pressing his thumb against her lip and moaned when she sucked it. “You don’t know… how long I’ve wanted you.”

His hands settled on her thighs, tightly gripping the soft flesh as he continued to pound her. Brown eyes, darkened with lust, marveled at how much he was stretching her open. “Don’t know how long I’ve dreamed of this…” he growled. “Of fucking you, making you mine.”

She clenched again and wailed something that resembled his name. Sebastian laughed deliriously.

He spoke again, aware that she was holding on to every word despite her fucked-out state. “You must’ve cursed me, haven’t you— mmh, fuck— trade that Azkaban sentence with this obsession… this need for you…”

“...Se— ah!” the girl tried, and failed, to formulate her first, proper word ever since he broke her in. She was a total wreck. Tears had formed in the corners of her eyes, her lips swollen from the kiss and from how much she’d bitten it, her breasts bouncing tantalizingly with each thrust of his hips. Everything only spurred him on.

“Now you’re mine,” his hand slithered up, pressing against her inflamed scent gland. “I should claim you...”

“Please!”

Finally, she managed to form a proper word and it sounded like it was punched out of her chest. Breathless, hysterical, desperate. Sebastian’s pace faltered a little at the unabashed invitation.

“Seriously? You’d like me to claim you, omega, is that it?” he was now licking at the gland, intoxicating his lungs with the scent of mallowsweet and cedar. “Shall I bite here?”

“Y– ye— alpha!”

That was the only confirmation he needed. Elation bloomed in his chest, so intense that Sebastian feared he mistook greed for joy. Deftly, he pushed her thighs up, almost folding her body in half. The position enabled him to reach even deeper, eliciting a shrill cry from her.

“I’ll claim you. You’ll be bound to me. Even if you change your mind tomorrow, there’s nothing you can do about it.”

He was treading on a dangerous zone, he realized. The possessiveness and desire he’d thought he’d buried long ago had now resurfaced, unable to resist when the love of his life presented herself to him so willingly. Because why should he refuse something that was offered to him?

But her walls eagerly pulsated around his girth and more slick gushed out of her abused pussy. A clear sign that she was thrilled by the idea. Sebastian grunted.

“Speak up, omega, use your pretty mouth.”

“YES!” she screamed, trying, with great difficulty, to get the words out of her mouth. “Mate me, mate me— Iwantnothingmore—”

Cursing through his teeth, Sebastian pushed her thighs up, almost folding her body in half. He set a punishing pace, roughly fucking her until she started skidding along the bed, the lewd sound of their fucking filling the room. Gone were all the gentleness he tried so hard to reserve for her. Not that she minded, strings of incoherent pleas like Sebastian, alpha, and please continued to leave her lips.

Soon, he felt an engorgement at his cock and she keened whenever it hit her drenched core.

“—want my knot, don’t you? What if I breed you, huh?”

She cried, strings of pleas left her mouth as her walls tightening impossibly hard around him that Sebastian didn’t even know how his knot could fit inside her small pussy. But he didn't think too much of it, couldn't find it in him to care, not when she responded so enthusiastically to his debauched idea.

“Fuck— is that what you want, angel? Want me to get you pregnant?”

Another lewd moan, she curled her legs possessively around his hips.

“Ye– ah, ah, ahh! Plea— Seb—”

When his knot finally breached her little hole, she wailed, voice rising in an obscene, lustful tone he never knew she could reach. Sebastian vowed to make her sound like that more often in the future.

“Ohhh, fu— angel, you feel so good around me. So tight…” he gritted through his teeth. “So ready… for my seed.”

“Please…” she begged hoarsely, overwhelmed by the idea of being bred. Eagerly, she exposed her scent gland to him once again, an invitation. “Oh… please…”

“I love you,” Sebastian sighed, burying his face in the crook of her neck. “I love you… come for me, angel. Take me.”

His teeth finally sank into her scent gland, breaking the skin, filling his mouth with her blood. A loud scream ripped its way out of her throat, her body trembling from head to toe as she came all over his cock. The tightness of her core sent him over the edge. With a groan that sounded almost pained, Sebastian reached his climax, filling her up to the brim while her walls continued to milk him dry.

“F– uck! Oh, fuck…” he moaned as ropes of cum continued to spurt out of him. His body felt heavy and boneless, melting against her own as he steadied his breathing.

Carefully, he rolled over so she was laid on top of him. The girl didn’t even seem to notice the sudden shift. There was a blissful look on her face as she relished the warmth and fullness in her belly. Slowly, they regained their breathing.

“That was…”

“Everything I’ve ever hoped for and more,” she finished, slurring on her words, but sounding a lot more lucid now that her hunger had been sated. For the time being, at least.

Sebastian’s heart leaped hopefully at her words and she must’ve sensed it because she looked up at him with a tired, happy smile. She placed her hand on his cheek.

“I love you, too,” she said with a quick peck on his lips. “I love you, I love you, I love you,” she said again, a kiss for each confession. By the third time, Sebastian held her in place, not allowing her to pull away as he deepened the kiss. Soft giggles filled the room when they pulled away.

“I…” he tried to speak, professing his love to her with grandiose words and undying promises like he had always imagined. Tell her how much she meant to him. Yet it seemed that the words had abandoned him.

In the end, he only managed to ask, “Since when?”

“Mm, since you taught me Confringo,” her eyes twinkled in delight when he sucked in a breath, surprised at the revelation. “And it only grew after you broke the school rule to visit me during my heat. I remember that, Seb.”

This time, he spluttered. They never did talk about that visit, not when she had acted like it had never happened and he was too afraid to risk it all. Courage was not something Sebastian typically lacked, but if it came to her… after everything that had happened, he found himself desperate to play it safe as long as he could stay in her life.

“I thought you forgot about it…”

“I didn’t. I was just… too shy, I suppose. I did touch myself in front of you and I… I was afraid you’d reject me.”

“Anyone who would reject you is out of their mind,” he replied, still very much trying to process his new reality.

Her cheeks turned pink. “What about you? Since when?”

“Since I saw you taking down those trolls,” he admitted, averting his gaze in embarrassment when she inevitably laughed. It wasn’t at all a mocking laugh, though, she sounded pleased. “It was… a small crush at first. Anne was a priority back then and I thought…”

He paused, trying to find the words that best portrayed his feelings. She waited, as patient and kind as ever.

“And then you prevented me from going to Azkaban and I just… I fell hard,” Sebastian whispered, calloused fingers tracing her face with as much reverence as a servant would show to his goddess. “You became my purpose. My rhyme and reason. I… you’ve had me wrapped around your fingers even without claiming me and I found myself not minding that. I found myself dreaming of being yours.”

She watched him with rapt attention, clinging to his every word like how the sunflower faithfully followed the sun. Her lips parted and she let out a shaky breath. “Why didn’t you tell me?”

“I had to protect you from my darkness, didn't I?”

“Hush, there is no darkness. I only see you.”

There was no way he could wash the blood that had stained his hand. The sins that he committed were a weight he had to carry for the rest of his life. Yet at that moment, just for that one, precious moment, he felt as if he had been washed clean. A brand new life for the sinner.

“Claim me,” the words flowed out of his mouth naturally. “Take all of me.”

Her eyes shone like starlight and her smile was as warm as the rising sun. Carefully, she inched closer to his exposed neck, one hand settling on his bicep, the other pressed flat against his chest, feeling his heartbeat under her touch. Sebastian sucked in a breath when her lips softly brushed against his scent gland, sighing when she gave it light kisses.

Then she opened her mouth and sank her teeth into his flesh.

There was pain at first, a pinch that made him hiss when her fangs broke his skin and punctured his flesh. But then, warmth.

A sense of belonging. Completion. Coming back home.

A void being filled inside him, light vanquishing the darkness that had been haunting his steps since he was a young boy. The girl who saved him now claimed him as hers and it couldn't get any better than that.

Sebastian gasped, hand settling at the small of her back, pushing her flush against him.

When she pulled away, she was smiling.

“Now we’re mates.”

Their eyes met and they shared a laugh. It was soft, it was happy, it was laced with a hint of disbelief, still reeling at the fact that they now truly belong to each other.

“We’re mates,” he affirmed with a kiss.
