Xavier knew he wasn’t the most patient person.
But even patience, he thought, has limits. And he had been patient and reasonable for a week, to be precise.
It all started ever since that damned new recruit entered his team. He didn't know why, but he kept coming to you for everything—directions, advice, even trivial nonsense like lunch recommendations. It was almost as if on purpose.
This afternoon was no different. Xavier had been looking forward to having lunch with you—just the two of you. You’d promised him, after all.
And yet—
“There was this one time I got trapped inside the N109 Zone—”
“N109 Zone!?”
“Yes!”
“Really?! What did you do then?”
“Hmm, so at first, I was in total panic, but then—”
For the past 15 minutes, your lunch break had been taken over by recounting your tales of valor as a hunter to the new recruit. Nearby, Xavier sat in brooding silence, scathingly sparing him a glance. The slight frown on his face said it all—blatant disinterest and a touch of irritation.
And you too... why are you engaging him so enthusiastically?
Then again, given his age, Xavier knew he had to be mature about this. He tried, really. If it had been someone like Jeremiah, he might have let it slide.
But there was just something about this new recruit—Sean, was it?—that rubbed him the wrong way.
“Whoa, you're so cool, Miss Y/N!” Sean exclaimed, his eyes sparkling with admiration. “Not only are you pretty and talented, but you're also incredibly skilled! What do you even lack, eh?”
“Really, it's not that much,” you giggled, brushing him off. The way you got sheepish only made Xavier’s annoyance flare even further.
“Let me guess— a boyfriend!”
So that’s what it was. Now Xavier understood what about Sean that set him off. The entire time you’d been talking, he had been giving you those googly eyes.
He didn't like it one bit. He looked ridiculous while doing it.
Despite being silent as a mouse all the way, before he could stop himself, he blurted, “She has a boyfriend already.”
You turned to him in surprise, clearly not expecting him to announce it so bluntly.
“Oh...? Xavier, you know who her boyfriend is...?” Sean turned to him with curiosity.
He noticed it. How his expression fell ever so slightly upon he told him that you were already taken. Xavier huffed and stuffed his mouth with his ramen.
“Yeah. Her boyfriend lives next door.”
Technically, he lived upstairs, but the detail didn’t matter. He just needed to make his point known.
And somehow, for the rest of the day, the new recruit finally seemed to develop some sense—at least enough to stop hovering around you so frequently. Particularly when Xavier was nearby.
“Xavier... why did you tell him that?”
You fell into step beside your quiet boyfriend as the two of you headed home that evening, tilting your head as you replayed the events of the afternoon.
Xavier gave you a brief glance before looking straight ahead again, ignoring your question.
You observed him. There it was again—that gray cloud hovering over him. It always seemed to appear when he was in a bad mood.
Puckering your lips, you pressed further. “We haven’t even told anybody else about our relationship... And what you did there—you’re literally telling him we’re dating.”
“So what?” he shot back, his tone sharper than usual. “Are you afraid people might find out we are? Or—”
Xavier abruptly stopped in his tracks, turning to face you. His usually vibrant blue eyes darkened, piercing into yours with a sharp gleam. “Are you afraid he will find out?”
There was something in his gaze that held you captive—that made your silly heart skip a beat.
“N-no...” you looked away, swallowing the heat that were about to take over your face. Why does Xavier look kind of... hot like that...?
Your cheeks warmed regardless, but you had to appease him. “Like I told you before, I just thought it’d be easier if this stays our little secret. It’s less of a bother if they don’t know…”
Reaching for his hand, you gave it a reassuring squeeze and flashed him a soft smile. “Besides, why would I be afraid if he knows? My boyfriend is cool, handsome, and the best hunter there is.”
You watched as Xavier's expression softened, the tension melting away. A faint blush crept up his cheeks too, and the gray cloud that had loomed over him finally disappeared. He squeezed your hand in return, looking away as if to hide the way he got bashful.
Adorable. For all his brooding, your boyfriend was surprisingly easy to soothe.
For the rest of the walk back to your apartment, you two remained hand-in-hand, the tension of the afternoon slipping away with each step.
. . .
You were staying over at Xavier's place tonight. After a relaxing bath and a hearty dinner, the two of you found yourselves standing side by side in the kitchen, doing the dishes together.
It was mundane things like this that Xavier considered his favorite routine to do with you. Just as you handed him the last plate to dry, you spoke up, your voice breaking the quiet hum of contentment—
“Xavier, can I ask you something?”
“Hmm?”
“I was just thinking... Sean seems nice and friendly, but from what I’ve seen, you seem kind of... hostile towards him.”
At your words, a frown etched itself onto Xavier’s forehead as he turned to face you fully. You seemed so oblivious, standing there with a look of genuine curiosity.
“Do you really not know?” he questioned you incredulously.
You blinked. “Know what?”
Damn it. Xavier sighed and put down the dish he was holding, but the words faltered on his tongue as a sour expression crossed his face. “No matter,” he muttered under his breath.
He took a deliberate step closer, his movements slow and heavy, and you instinctively backed away, only to find yourself pressed against the window, unable to retreat further.
He stood in front of you now, his arms caging you in, creating a barrier that sealed off any chance of escape.
Uh-oh. Apparently, you had flipped that switch—
“So,” he said, his voice low, his blue eyes boring into yours, “while Sean is nice and friendly, I’m hostile, huh?”
The air between you grew thick, and you could feel your pulse quicken under the weight of his gaze. "That's not what I'm getting at—"
"He's been eyeing you all day, following you around... getting lunches with you—"
In that moment, your phone erupted to life, its ringtone cutting through the tension. It sat on the small table near the windowsill, and Xavier gave it a quick glance, his expression darkening upon seeing Sean's name flash on the screen.
"Oh?" His voice dropped lower, a dangerous glint flickering in his eyes. "He's now calling you at nights too?"
"No!" you quickly refuted, your words tumbling out almost too fast. "Xavier, don't get the wrong idea—"
He tilted your jaw to face him, holding your spooked gaze. "Then what idea am I supposed to be getting when he's so blatantly pursuing you and you don't even do anything about it?"
The plot twist is... you know. Of course you knew it when a guy was trying to make a move on you, you just pretended not to notice it because it was easier that way. You didn’t know which devil had planted this rotten idea in your head that made you want to push Xavier to the edge, just to see how he'd react when he held nothing back—
The call tonight was a coincidence though, but definitely fueled your lover's ire even more. It was a dangerous game, but now that you’d crossed this line, you couldn't go back any longer.
Your lips curled into a bewitching smile then, and your boyfriend was almost mystified. "So, what will you do to me?"
Xavier looked at you with slightly widened eyes, not expecting your boldness at all. But then he grimaced, as at the same time, the irritation in his veins suddenly flared up—
With a swift, fluid motion, he turned you that you faced the window, his right arm wrapping around your waist from behind as he pressed his body against yours—his hardness pressing, almost poking you.
"You're so clueless," he growled into your ear before going after your neck, sucking hard and fast. His hips began to grind against you, pressing harder with each movement. "Too damn clueless...!"
His fingers that gripped your belly moved then, slipping inside your frisky nightgown to finger you— and you lost all your wits in that instant. "Ah-h—!"
Two of his fingers pumped in and out of you, dragging them almost rashly, and it took everything in you to stay upright. "X-Xavier!"
"Mmph," he breathed against the skin of your neck, his other arm pressing you against him tighter. "You asked for it."
Your thighs were trembling in no time, and your breaths came in shaky moans. Your boyfriend was not exactly gentle, but this is probably the first time in a while that he was being rough without reservations. While you wanted to protest, it felt too good—
He turned your face towards him then, crashing his lips on yours.
It almost felt like you were punished, but you couldn't do anything about it. The tension in your lower belly was steadily building, ready to snap at any moment, and the way his fingers relentlessly hitting that one unforgivable spot was starting to made you dizzy.
"Ah—ngh!" You finally shuddered when you reached your climax. It was freeing when you felt yourself burst on his fingers, the release smearing your thighs.
And right then your knees buckled—
But Xavier immediately got a secure hold over you, lifting your body effortlessly into his arms, one hand supporting your knees, the other cradling your back. Through your teary eyes, you met his gaze once more. His expression was unreadable, a dark haze of disapproval clouding his features.
“I’m not done yet.”
He brought you over to his bed, gently lying you down despite the roughness of his voice. He parted your legs, getting himself between them—
Ring! Ring!
The shrill sound of your phone pierced the coolness of the room, and you almost jolted.
But your lover... the sound was like a spell to him, only intensifying his irritation as his features twisted with frustration, and you knew that he was about to take it on you.
As if changing his mind, Xavier suddenly flipped you over that you laid on your stomach and straddled you from behind. He quickly turned your head to face him and claimed your lips in a deep, urgent kiss.
“Mm, hmmp—!” The ringtone of your phone blared in the background, a jarring sound that wasn't pleasant at the slightest. It wasn’t until it finally stopped that he pulled away from the kiss.
You were gasping for breath, your chest heaving, and a stray tear slipped from your eyes. Xavier stared at you, and gently wiped it away with his thumb.
Flushed, sweaty, tearful... you looked so enchanting in his eyes in that moment. He almost felt bad that he had manhandled you this roughly.
Almost.
His hands gripped your waist, and he paused, his gaze locked with yours, silently seeking your approval— or more like, commanding you to give it to him.
In response, you arched your back— a silent affirmation, bracing yourself.
From then on, he was no longer holding back. He tugged your panties down and let his throbbing member out of his pants. It was laughable how insatiable he was— both of you were still clothed, save for his unbuttoned shirt, but he was already this aroused and hard.
He nudged forward, his tip breaching your entrance. The feeling of that familiar stretch left you keeling, babbles and whimpers falling from your lips as he slowly eased into you.
It was hard to take him in fully, and you were a mess of breathy gasps the moment you did. But you were in for the main ride when he started ramming into you, pushing in and out of you in a merciless pace.
"Ah... Xavier!" you panted between thrusts, feeling how it started to be too much for you the more he went on. "Ahh, hrah!"
Behind you, Xavier groaned in reply, his lips sucking your shoulder as his hips quickened, striving to bring you to the peak faster. One of his large hands dug into the skin of your stomach, urging your back to arch more, while the other clasped yours, fingers entwined in the sheets.
He watched intently as your face twisted and contorted in ecstasy, a surge of pride swelling within him, greater than he thought possible.
It was mind-blowing, slightly forceful, and your senses were all heightened. The harsh pace drew cries from your lips, your tears falling to the sheets, yet the pleasure also catapulted you into the stars—
The sinful delight of having him so deep within you.
The sinful rapture of being thrusted over and over.
“Ahhh!” And then, all at once, it was as if heaven and hell collided in a cataclysmic burst. Everything inside you shattered as you cried out—a scream morphing into a high-pitched gasp—as the two of you reached the climax together. Your body trembled uncontrollably, your walls clasped around him impossibly tight as Xavier filled you with everything that he had in one shot.
You collapsed against the sheets like a ragdoll, the pressure finally easing from your sore spine.
“Hello? Yes, it’s Xavier...”
The morning after. You stirred awake, your mind still foggy with sleep, as muffled voices filtered in from outside the bedroom.
“I have to take an urgent leave today...”
You were still utterly drained, your body heavy and unwilling to move. Instinctively, your hand reached out to your side, searching for your lover, but the spot was empty.
“Yes. Y/N too. She isn’t well today... We will be back tomorrow...”
You let out a soft, tired whine, your voice plaintive, as you lay sprawled across the bed, wishing for his warmth to return. Honestly, everything was still sore, and you were this close to tears again.
The door then opened with a creak not long after, and you let out a whimper, squeezing your eyes shut.
“Are you awake...?” Xavier's voice was soft, almost hesitant, as he stepped closer to the bed.
You blinked up at him, your vision still blurry. He was already dressed, his crisp appearance in stark contrast to your disheveled state. In his hand, he held a small plastic bag.
“What’s that...?” you mumbled, your voice hoarse as you struggled to prop yourself up, curiosity flickering through your tired gaze.
“Don’t get up too quickly,” Xavier murmured, his hands steady as he caught you mid-movement. He guided you back down and tucked the blankets snugly around you, his touch gentle yet firm. “Just rest for now.”
A low hum of contentment escaped you as you leaned into his touch. Your bleary eyes focused solely on him, and despite himself, Xavier found a smile tugging at his lips.
“I just went to the drugstore downstairs to get you some painkillers,” he explained, lifting the small plastic bag slightly. “Take them after you’ve had some breakfast later.”
He then fixed you a bashful grimace, looking down. “Sorry for... uh, last night... I think I’ve pushed you too far.”
His fingers reached out, brushing gently against your cheek. The same fingers that had driven you to the brink of madness the night before now so tender against your skin. “You were crying,” he murmured, guilt lacing his voice. “I feel bad.”
“Mm-hm, so that’s what happens when you don’t hold back at all,” you snickered softly, the corners of your mouth curving despite the lingering ache in your body.
Xavier shifted his gaze away, his confidence faltering. “Will you... hate me for it?”
It was hard to contain your smile from breaking out into a grin. Your boyfriend, a ferocious wolf in a sheep’s clothing, had no need for this shy charade when he had railed you that hard last night.
“No, but you’re going to have to make it up to me. I can’t even walk now.”
Xavier blinked before he patted your head. “Yeah, I’ll fulfill any of your wishes,” he sighed in relief, a hint of amusement creeping into his voice. “So, what is it?”
You paused for a moment, then with a mischievous glint in your eye, you said, “Take me to the bathroom? I want to have a shower first.”
And, of course, he obliged. With a effortless motion, Xavier scooped you up into a princess carry, holding you close. His arms cradled you with care, and you rested against his chest, the warmth of his embrace offering a sense of security.
Just like that, you spent the rest of the day as lovers, sleeping in with careless abandon, unburdened by your duties.
Epilogue
Later in the afternoon, you were once again deep in a sleep as Xavier cuddled you close, when suddenly the doorbell of his apartment rang incessantly.
Frowning, Xavier carefully eased himself out of bed, making sure not to disturb your slumber. He moved quietly towards the door, and when he saw the intercom, his frown worsened.
Sean, the newbie, was at his doorstep. He had half a mind to ignore him, but after a beat, he decided to open the door.
“What do you want?” his voice sharp with annoyance.
“Oh, Xavier!” The guy was stunned for a moment as his eyes lingered on Xavier’s chiseled abs, exposed through the his unbuttoned shirt. “O-oh, so... I’ve been trying to ring the doorbell to Y/N's apartment to give her a fruit basket to wish her a fast recovery, but she’s not answering—” he hastily explained, gesturing toward the basket in his hand. “Can you reach her—?”
Xavier felt like popping a vein at how meddlesome this guy was. Was this guy an idiot? Didn’t he realize by now that he was your next-door boyfriend?
Nevermind. The hard way it is.
“She’s with me.”
“H-huh?”
He shot him a pointed look. “Don't think you’ll have a chance with her, newbie.”
And with that, he shut the door in his face.
