The Royal Military Academy's Impostor Owns a Dungeon [BL] novel Chapter 569

Chapter 569: Thorough Testing

Luca found himself pressed against Xavier as if suddenly weakened by the sensation.

He figured the suit was a bit more sensitive than the last one, but never did he imagine it to be like this!

"!!!"

Xavier’s hand continued to linger at Luca’s waist, his thumb brushing deliberately over the sleek, form-fitting material beneath his clothes.

The subtle shift in texture caught his attention instantly.

"...So what’s this?" His voice was calm, but there was a glint in his eyes that made Luca’s stomach flip.

"It’s—ah—it’s nothing important," Luca stammered, his shoulders twitching as if he could somehow pull away without actually moving.

But Xavier’s arm at his back kept him neatly in place, their bodies still pressed close from before.

"Nothing important?" Xavier repeated, tone dripping with disbelief. His fingers traced along the curve of Luca’s hip, finding the faint seam that ran under his tunic. "Hmm. Feels important."

The little inventor swallowed hard. "It’s—it’s just a side project."

Xavier didn’t look convinced. "A side project that makes you shiver like that?" His thumb pressed again, slow and deliberate.

"Hhh—!" Luca’s breath caught, his knees drawing in reflexively around Xavier’s hips.

That earned him a quiet chuckle. "Now you’ve got my attention. Tell me."

Cornered, Luca fumbled for an explanation, words tumbling out in a rush.

"I was trying to design something for pilots. A suit that redirects spiritual energy more efficiently. You know how a lot of them release through their whole body instead of just key points? This could help channel it directly into the mecha’s systems instead of wasting it."

Xavier listened, head tilted slightly, but his hand never stopped moving.

The soft glide of his palm over the suit’s smooth surface made it hard for Luca to keep a steady rhythm in his explanation.

"It’s... still experimental," Luca added quickly, as though that excused the way he was tensing under every touch. "And it’s... um... more sensitive than I meant it to be."

"Sensitive," the wolfish husband repeated, and there was no mistaking the interest in his voice now. His fingers followed the seam upward, then back down in a slow, deliberate path. "Where, exactly?"

Luca’s breath hitched again, and his voice wobbled. "Xavier—"

"This spot?" The prince pressed a little more firmly against the side of his waist.

Luca’s head tipped forward against his shoulder, teeth catching his lower lip. "Hh—yes..."

"I see..." Xavier’s tone deepened, thoughtful in a way that made Luca shiver.

Before the little guide could gather himself, Xavier eased him back against the wall again, stepping into his space until there was nowhere else to go. "Move for me."

"W-what?"

"Just a little test. Walk."

"I can’t—it’s too—"

"Try."

Reluctantly, Luca stepped forward as Xavier side-stepped for him. The suit’s slight stiffness made every movement a little restricted.

But then Xavier followed, his large hands ghosting over his hips to adjust his stance, guiding his shoulders when he slouched. The coolness of those hands seeped through the material, and each adjustment sent another tremor racing up Luca’s spine.

"Mm. Still too stiff," Xavier murmured, leaning in as if to study the fit—though his voice carried something far from professional detachment. His breath brushed Luca’s ear. "We could maybe try to adjust this, though; you might have to keep your voice down."

Luca’s pulse jumped. "O-okay..."

The low rumble of that suggestion sent a fine shiver down his arms, and Xavier felt it. His lips curved slightly against Luca’s temple. "Good boy."

The praise made Luca flush to the tips of his ears, but he obeyed. Every sound that tried to escape after that was bitten back into a muffled hum.

Still, the more Xavier’s hands explored the contours of the suit—palming the curve of his thigh, smoothing up over his ribs, pressing into the small of his back—the harder it became to keep still. His breathing quickened, his body leaning instinctively into the touches he swore he was trying to avoid.

At one point, Luca shifted just enough to press himself more firmly against Xavier’s frame. It wasn’t calculated—at least not consciously—but the soft sound he made when their bodies aligned like that was enough to make Xavier’s restraint falter.

"Testing the suit?" Xavier asked, his tone all silk and shadows.

"...M-maybe," Luca admitted, still trying to keep his voice low.

"Then I should help you run it through... more thorough trials," Xavier murmured, his hand sliding once more over the most sensitive seam. The contact pulled a sharp breath from Luca before he remembered to stifle it.

"Yes...?" The single word was quiet, but so full of wanting that Xavier’s smile turned slow and wicked.

"Mm. But for now... keep wearing this one," he said, his thumb brushing one last time over that seam. "I think I like this model."

Luca could only nod, his face hot, heart pounding, already dreading—and anticipating—what the next "inspection" would entail.

Xavier didn’t move away.
