The Royal Military Academy's Impostor Owns a Dungeon [BL]

”Ngh!”

Luca’s head flew back as a sharp cry escaped him. His arms clutched onto Xavier’s leg for support as he finally, somehow, managed to lower himself fully. The sheets beneath him bunched under his knees, the mattress dipping with their weight, and the little guide trembled as he realized he had taken him to the very hilt.

For a long second, the room was filled only with the sound of his ragged breathing. His golden eyes fluttered open, dazed and glassy as he looked down at his husband.

Then, unexpectedly, Luca smiled.

It was wobbly, shy, and proud all at once, like he had just finished a tricky mecha modification. He blinked through his lashes and whispered, trembling but sincere, ”See? I... I did it. I rewarded you properly this time.”

Xavier froze.

The words hit him harder than the sensation itself. His pulse pounded as he looked up at the flushed little figure sitting above him, smiling like that, thinking this was already the peak. His adorable, impossible wife.

Something in Xavier hardened even more.

He let out a shaky breath, the corner of his lips tugging upward in disbelief. ”Luca...”

”Hm?”

”You see, my love, we haven’t even started.”

”...?”

The smile dropped. Luca blinked once. Then twice. His eyes widened in horror.

”What do you mean ’started’?” he squeaked, his voice shooting several notes higher than usual.

The prince’s quiet laugh rumbled from beneath him, only making it worse.

Luca’s panic flared immediately, his arms trembling as he scrambled to make sense of it. ”Wait, wait, this isn’t it? You mean... there’s more?!”

And in his frantic surprise, his hips jolted.

The movement made him rise and sink just slightly. Enough for the little guide’s body to shudder again with a startled moan. His face went crimson in an instant, mouth opening helplessly as if he had just betrayed himself.

”Ah—!”

His expression was priceless. A mess of horror, shock, and overwhelming pleasure, wide golden eyes shining with unshed tears and lips trembling as he realized what just happened.

Xavier stared. Absolutely undone.

If he thought Luca was beautiful before, then this was unfair.

His flushed little wife, black hair sticking to his forehead, golden eyes glassy and wet, looking scandalized yet utterly lost to sensation. Xavier’s jaw clenched as he held himself back, fighting every instinct screaming to flip them over and take everything for himself.

But then the surprised guide, who hadn’t realized how much of a reaction he had just caused, blinked down at Xavier with the same expression—because he was pretty sure he saw his husband flinch.

That realization settled into him like a spark.

”Oh,” Luca breathed, chest rising and falling, his voice trembling but growing bolder.

He thought he should probably try moving.

So he did.

Tentative at first, lifting himself just enough to feel the cool air graze his flushed skin before he sank back down again.

The sensation rolled through him like fire. He shuddered violently, moaning before he could bite it back.

”I-I...” His words faltered, breath breaking as his body trembled. ”I feel... so full. So—”

Then he looked at Xavier again.

Azure eyes, strained and glowing, locked onto him with raw hunger.

And that sight—those eyes, burning with something Luca had never seen before—snapped something inside of him.

Luca’s body moved before his thoughts caught up. He rose again, slower, then sank down with a trembling cry. His hands now pressed against Xavier’s abdomen for balance as his thighs quivered.

The little guide had never been bolder.

And Xavier, staring up at him like he was both a miracle and a curse, could only groan, utterly lost to the sight.

Surely, it was possible to just lie beneath his wife.

Right?

He told himself that. Convinced himself he could stay still, breathe shallow, and endure until morning if it meant Luca wouldn’t break apart in his arms.

But he also knew he might not make it to tomorrow like this.

Xavier’s azure eyes darkened as he felt how Luca’s trembling body leaned forward over him, the golden gaze hazy and unsure. And then, unable to stop himself, he snapped. His hips thrust up sharply.

”Ahhn—!”

The yelp that burst out of Luca was high-pitched and unguarded, cut through the air like a struck string. His back arched violently, his hands slipped against Xavier’s chest, and for a moment he almost toppled over with the sheer intensity of it.

The sound. That raw sound.

Xavier’s pupils dilated.

He did it again.

”Hyahh—!” Luca squeaked, his voice cracking as his thighs shook. He stared down in wide-eyed disbelief, panting, dazed. ”X-Xavier... what—what are you—”

The starving wolf beneath him groaned, voice deep and ragged, his grip sliding up to steady Luca’s waist. ”Being greedy,” Xavier confessed, tone shaking with hunger. ”I should be punished later for it. Because I’m taking more reward than I deserve.”

Luca’s mind blanked. His husband—his prince—was talking like a sinner begging for forgiveness while thrusting into him.

”P-punished?!” Luca stammered, his face redder than it had ever been.

Xavier’s lips twisted into an apologetic grin. He surged up again, hips slamming into that sweet spot buried deep inside Luca that the little guide saw white.

”Ahhhhhh—!”

Luca screamed, the sound tearing from his throat without dignity. His nails raked over Xavier’s shoulders as he clawed desperately for something to hold onto. His entire body convulsed, his thighs tightening helplessly as the intensity ripped through him.

He was cumming.

Again.

So violently that his voice broke, his chest heaving as the molten pleasure shook his core apart.

”Luca,” Xavier growled, the sound guttural and unrestrained as his own control snapped. His hips pounded up into his wife with raw abandon, no longer just receiving but taking—taking as if this might be their last chance to breathe.

”Ahh—haaah! Xavier!”

”I just—Ahh!”

The little guide wailed, his golden eyes glazed with tears, every sound escaping him a plea and a song all at once.

The bed creaked beneath them, the sheets bunched in Luca’s fists as Xavier drove into him harder, deeper, his hands finally sliding down to cup Luca’s quivering behind as he held him there.

The rhythm was brutal now. Consuming. Each thrust lifted Luca slightly before slamming him back down onto Xavier’s length, their bodies colliding with wet, obscene sounds that filled the room.

”Hnnngh—ahhh—!” Luca keened, sweat dripping down his temple, body twitching uncontrollably. He felt like he was dissolving, every thrust tearing away what little composure he had left.

And then—

”Ahhh—! Nghhh—!”

Release tore through him again, stronger, merciless, his body slumping forward with a cry as his orgasm wracked him raw. His chest pressed against Xavier’s, his trembling arms giving out.

The prince caught him instantly, one hand splayed across Luca’s back, the other gripping his rear as he gave a final, desperate series of thrusts. His voice broke into a guttural groan as he spilled deep, his entire body straining beneath the weight of pleasure.

They collapsed together.

Luca’s vision swam, hazy and blurred, his golden eyes barely able to focus. He panted into Xavier’s shoulder, every breath shaky, broken, as though his soul itself had been shaken loose.

The room was filled only with their ragged gasps, the faint creak of the mattress beneath them, and the racing of two hearts that had finally given in to the storm.

The storm had passed, but the aftershocks lingered.

Their breaths still came ragged, shallow, almost broken in the quiet room. Luca lay sprawled against Xavier’s chest, golden eyes half-lidded, his body limp as if he’d been wrung dry. The faint glow of sweat and warmth clung to him, every rise and fall of his chest matching the slow, steady thud beneath his ear.

Xavier stroked his back once, twice, the prince’s azure eyes softening with a mix of guilt and unrepentant desire. His lips parted, voice low and gravelly.

”Luca... I—”

But before the words could escape, a weak little hand rose.

A single finger pressed against his mouth.

Luca, cheeks still flushed, pouted faintly. His voice was hoarse, trembling, but steady enough to land the blow.

”You told me earlier... not to apologize when you don’t mean it.”

Xavier froze. Then his lips curved helplessly against that small finger.

He huffed out a laugh, deep and warm, shaking his head at the boldness of this exhausted little creature who had somehow stolen his every defense.

The prince kissed the fingertip softly, reverently, before lowering his voice into a murmur meant only for him.

”Yeah. I was bad,” he admitted, his tone sinful and tender all at once. ”How could I ever apologize... for something I constantly dream about?”

Luca’s eyes widened slightly, his pout faltering, his lips parting in surprise.

But Xavier didn’t let him answer.

He leaned up and claimed his mouth, slow and thorough, pulling his wife into another kiss that left no space for guilt, only heat and aching devotion.

The world outside could burn, the stars could fall, and the universe could rage.

But here, in this bed, in this moment, there was only them.

As their lips locked again, Xavier shifted, strong arms sliding around Luca’s waist. And then—

”Ah!” Luca gasped as the prince suddenly rolled them over, the quilt tangling around their legs as the room tilted. Their mouths never broke apart, only deepened, the kiss turning hotter with each stolen breath.

When Xavier finally pulled back for air, Luca blinked up at him, dazed and flustered. ”W-what are you doing?”

The wolf above him grinned, azure eyes gleaming with dangerous amusement. His voice was low, playful, and shameless.

”We can’t waste your efforts on this suit, can we? We should make the most out of testing it.”

Luca’s golden eyes went wide. His lips parted in shock as he stared at the man looming over him.

And in that instant, with that hungry gleam in Xavier’s gaze, he was certain.

His husband wasn’t just a prince. He wasn’t just a man.

He was a wolf.

A big bad wol—mpfh!
