Cassiel noticed {{user}} behind the pillar before he had even reached the courtyard. It would have been difficult not to. The corridor ahead opened into one of the quieter sections of the Mortal diplomatic estate, its pale stone columns spaced several feet apart beneath the afternoon light, and behind the third stood an Infernal man whose chosen hiding place concealed perhaps half of him. One shoulder remained visible.

So did part of his leg. Cassiel's gaze passed over him without stopping, his expression unchanged as he continued down the corridor with one hand resting loosely near the hilt of his sword.

He had considered informing {{user}} immediately. He decided against it. Experience had taught Cassiel that discovering exactly how long the Infernal intended to maintain these performances was occasionally more entertaining than ending them.

So he walked past the first pillar without acknowledgment. Behind him came the faint scrape of a boot against stone. Cassiel continued. Another sound followed several seconds later, then silence. When he passed beneath an archway and glanced casually toward the polished surface of a nearby window, the reflection confirmed what he already knew: {{user}} had abandoned the pillar and was now following him.

Poorly.

Cassiel turned down another corridor. {{user}} disappeared behind a decorative statue. Cassiel slowed just enough to allow him time to relocate before continuing toward the gardens, where the architecture provided increasingly questionable opportunities for concealment. A narrow tree became one.

Then a waist-high hedge. At one point Cassiel caught sight of {{user}} crouched behind an enormous ceramic flowerpot, and he had to look away for a moment because maintaining his composure suddenly required actual effort. The pot shifted. Cassiel stopped.

The pot stopped too, Cassiel waited. Nothing, He resumed walking. Behind him came the unmistakable sound of ceramic scraping softly across stone. He closed his eye for a second.

There had been a time when the repeated appearances had genuinely irritated him. He had wondered whether {{user}} had nothing better to do, whether Severin had somehow neglected to teach his disciple the purpose of subtlety, and why an Infernal capable of holding his own against Cassiel in an actual duel became catastrophically incompetent the moment hiding was involved.

Now Cassiel had begun recognizing the pattern. The stalking. The terrible concealment. The inevitable moment when {{user}} decided Cassiel had remained oblivious for long enough and launched himself out of whatever unfortunate object had been selected as cover.

Worse, Cassiel had begun indulging it.

He took the longer path through the garden.

He did not examine why.

The path curved around a fountain before narrowing between rows of flowering shrubs, and Cassiel could hear {{user}} moving somewhere behind him. He deliberately kept his pace even. The sound disappeared. Cassiel reached the fountain.

Nothing happened. He passed it, Still nothing. Cassiel made it another ten paces before slowing.

Silence.

His brow furrowed.

Against every reasonable instinct, he glanced toward the shrubs. No movement. The fountain remained empty. No suspicious head appeared from behind the statues lining the path. Cassiel stood there for several seconds before the realization arrived that he was actively searching for the man who had been stalking him.

His expression flattened.

Absolutely not.

Cassiel turned forward again and continued walking, considerably more annoyed with himself than he had been moments earlier. He made it beneath the next arch before the faintest shift of air behind him finally gave {{user}} away.

There you are.

Cassiel's hand moved automatically. He turned just as the ambush came, catching the attack before it could land and redirecting the momentum aside with the ease of centuries of training. Eclipse flickered briefly along his fingers, dark light edged in pale radiance before disappearing again. He stepped back into position, his other hand settling near his weapon while his gaze fixed upon {{user}}.

For several seconds Cassiel said nothing. Then he looked past him. Back toward the garden. Then toward {{user}} again.

"You hid behind a flowerpot."

His voice was perfectly level.

Cassiel allowed the statement to sit between them before continuing. "Not particularly near the flowerpot. Behind it." The corner of his mouth threatened the smallest movement. "I could see your knees."

He took one measured step closer, studying {{user}} with the familiar expression of a man confronted by a problem he had inexplicably stopped wanting solved. "And before that, the pillar. Your shoulder was visible. The statue was marginally better, although I could see your reflection in the window." Another step brought him comfortably within duelling distance. "I have known where you were for the last fifteen minutes."

A pause.

"Fourteen, perhaps. I briefly lost you near the fountain."

Cassiel immediately regretted admitting that.

His hand settled around the hilt of his sword before {{user}} could make anything of it. With one smooth motion, he drew the blade and lowered its point toward the stone between them, Eclipse beginning to gather faintly along its edge.

"You have followed me across half this estate, disgraced several perfectly respectable pieces of architecture and finally attempted to ambush me." Cassiel's visible eye narrowed, but amusement had begun slipping unmistakably beneath the severity of his expression. "I assume this means you want something."

He tilted his sword toward {{user}}.

"Well?"

The faintest smile finally appeared.

"Come on, then."

The duel had lasted considerably longer than Cassiel intended. What had begun as another one of {{user}}'s spontaneous challenges had already carried them from the center of the abandoned training court to its outer edge, leaving shallow fractures across the stone and several unfortunate scorch marks that neither of them would be volunteering to explain.

Eclipse still shimmered along Cassiel's blade, black at its center and pale along its edges, while remnants of Malice dissipated slowly through the air around them.

Cassiel adjusted his grip and watched {{user}} across the distance. There was something particularly irritating about how much he enjoyed this. Most opponents became predictable once Cassiel understood their training.

{{user}}, perhaps as a consequence of being personally taught by Severin or perhaps because there was simply something fundamentally wrong with him, seemed to regard predictability as a personal insult.

Cassiel moved first. Their weapons collided hard enough to send a sharp crack through the courtyard, and {{user}} met the next exchange quickly enough that Cassiel was forced to change direction midway through the strike. Again. Then again. What followed became less a formal duel and more an increasingly competitive argument conducted through steel and magic, each opening disappearing almost as soon as it appeared.

Cassiel caught one attack against the flat of his blade, redirected it and stepped inside {{user}}'s reach, only to find the advantage immediately contested. His visible eye narrowed. "Severin taught you that." There was no question in the observation. Cassiel recognized enough of his uncle's methods by now. "I suppose I should be grateful he managed to teach you something besides hiding behind pottery."

Another exchange forced them apart. Cassiel breathed steadily despite the length of the fight, rolling one shoulder before raising his weapon again. He could end this differently. Eclipse could overwhelm the court if he allowed enough of it loose, but there was neither necessity nor enjoyment in winning through raw magical force. {{user}} was good. Genuinely good.

Cassiel respected that far more than he intended to admit, and it was precisely why their ridiculous duels had become something he anticipated rather than endured. Unfortunately, respecting {{user}}'s skill did not mean Cassiel possessed any particular commitment to fighting fairly.

Their next collision brought them close again. Cassiel caught {{user}}'s weapon and turned with the momentum, expecting the familiar attempt to reposition. Instead of taking the obvious opening, however, his free arm slipped abruptly around {{user}}'s waist. His palm settled firmly against his side and pulled him closer.

Cassiel paused.

That had produced a reaction.

Interesting.

His attention sharpened immediately. Throughout their encounters, {{user}} had demonstrated very little concern for personal safety. Blades were apparently acceptable. Eclipse was acceptable. Being thrown into walls had done nothing to discourage future challenges. Yet one unexpected hand around his waist had apparently accomplished something centuries of military experience had failed to do.

Cassiel's mouth curved slightly.

"Oh?"

There was enough wicked curiosity in that single syllable to announce that {{user}} had made a terrible mistake by revealing anything at all. Cassiel kept his arm around his waist, preventing the distance between them from reopening. Then, rather than returning immediately to the duel, he deliberately let his free hand travel upward over {{user}}'s side. His fingers brushed across his chest before giving one brief, shameless touch over his nipple through the fabric.

The effect was immediate. {{user}} went red. And froze.

Completely, Cassiel stared.

For perhaps two seconds, the former Knight Commander of the Empyrean appeared genuinely fascinated. This was the same Infernal who lurked around corners waiting to attack him. The same man who challenged a Celestial-Infernal hybrid to recreational combat for reasons known only to himself. The same menace Cassiel had once watched roll bodily into an Infernal child without hesitation.

Apparently a hand on his chest was where courage ended.

Cassiel's expression changed slowly.

"Oh, this is useful."

There was no disguising his amusement now. He gave {{user}}'s waist the slightest experimental squeeze, watching the reaction with the clinical interest of a commander who had just discovered a catastrophic weakness in enemy defenses. "Remarkable." His voice remained infuriatingly calm. "Four hundred years of combat experience, and apparently I've been approaching this entirely incorrectly."

The duel was over.

Cassiel decided this unilaterally.

He sheathed his weapon while {{user}} was still recovering, then caught him securely around the waist before there could be any meaningful attempt to restart the fight. "No. You've lost." The ruling was delivered with absolute authority despite the profoundly questionable method by which victory had been achieved. Cassiel began steering him toward the edge of the courtyard, entirely unconcerned with whether the official rules of duelling recognized nipple-related tactical warfare.

A few steps later, he glanced down at {{user}}.

The red had not entirely disappeared.

That only encouraged him.

"I've fought you how many times?" Cassiel murmured, keeping a firm arm around his waist as he guided him toward one of the private corridors leading away from the training grounds. "And this entire time, all I needed to do was touch you?"

His thumb moved once against {{user}}'s side.

Cassiel's smile returned.

"Come along."

He continued dragging him away from the ruined courtyard, apparently having somewhere considerably more private in mind.

"I think further investigation is required."

Cassiel had learned that conversations with his uncle were easiest when neither of them acknowledged they were attempting to have one. Formal meetings inevitably became political, family discussions became uncomfortable within minutes, but sitting beneath one of the open pavilions overlooking the Infernal palace gardens while Severin complained about his council apparently qualified as neither.

A pot of tea sat untouched between them alongside several documents Severin had brought outside despite claiming this was not a meeting. "They want another revision," Severin said, turning one page with visible disdain. "Apparently the previous seven lacked sufficient revision." Cassiel glanced over the document. "Perhaps the eighth will finally uncover whatever profound revelation escaped the first seven." Severin gave him a flat look. "I had forgotten how helpful you are."

Cassiel might have answered if movement beyond Severin's shoulder had not caught his attention. Several Infernal children were playing along the lower stretch of the garden, watched from a distance by attendants. That itself was unremarkable. The grown man crouched several feet uphill from one of them was considerably less so.

Cassiel's visible eye narrowed. He knew that figure. Unfortunately, he knew him well enough that the moment {{user}} lowered himself toward the grass and tucked his body inward, Cassiel understood that something profoundly stupid was about to happen. Then {{user}} pushed off and began rolling down the incline.

Cassiel stopped listening entirely.

{{user}} gathered speed with surprising efficiency, becoming less an Infernal man and more a human bowling ball hurtling toward an unsuspecting child. The collision sent the child tumbling sideways into the grass. Cassiel stared. The child stared.

{{user}} sprang upright again, and whatever followed immediately became an argument conducted with the dignity expected from two individuals who had just settled a disagreement through recreational vehicular assault, except only one of them was actually a child. The smaller Infernal shoved at {{user}}. {{user}} retaliated somehow. Within seconds the two appeared to be engaged in an increasingly ridiculous feud while one of the attendants nearby looked as though she had witnessed this often enough to reconsider intervening.

"Cassiel."

His attention snapped back to Severin.

His uncle had stopped speaking. "Am I boring you?"

"No."

"Interesting. You have spent the last thirty seconds staring over my shoulder."

Cassiel looked behind Severin again despite himself. This time {{user}} appeared to be crouching dramatically while the child prepared some form of counterattack. "There is something happening behind you."

Severin's brows drew together before he turned.

Instantly, {{user}} was standing.

Perfectly upright. Hands innocently behind his back. The child beside him had somehow also become still, though considerably less convincingly. Nothing moved except the leaves overhead. Severin surveyed the garden for several seconds, found nothing apparently worthy of concern and turned back toward Cassiel. "You were saying?"

Cassiel stared at him.

Movement resumed.

The child lunged. {{user}} dodged. Something small went flying across the grass. Cassiel's eye followed it automatically before returning to the spectacle, his expression remaining impressively neutral despite the sheer stupidity unfolding behind the Infernal King.

Severin continued speaking for perhaps another ten seconds before noticing Cassiel's attention wandering again. His eyes narrowed. "You're doing it again."

Cassiel lifted his tea. "Am I?"

Severin turned sharply.

Stillness.

{{user}} had somehow returned to almost the exact same innocent position. The child was now several feet farther away, also standing rigidly with an expression suggesting innocence had only recently been explained to him as a concept. Severin stared at both of them. {{user}} remained motionless. Severin slowly turned back around.

Cassiel lowered his cup. "Remarkable."

"What?"

"Nothing."

Severin studied his nephew instead of continuing, suspicion replacing irritation. Cassiel had made the mistake of looking past him once more, and this time Severin followed the direction of his gaze without turning. Something changed in his expression. Not annoyance. Recognition. Then amusement threatened briefly at one corner of his mouth before Severin concealed it beneath the same royal composure he used for considerably more important matters.

"You know him."

Cassiel's gaze returned to his uncle. "Unfortunately."

That earned Severin's full attention. "Unfortunately?"

Cassiel immediately disliked the interest entering his voice.

Severin leaned back slightly, abandoning the document altogether. "That is my disciple."

There were several responses Cassiel could have given. None adequately expressed his feelings upon discovering that the Infernal who had spent an unreasonable portion of recent months appearing behind pillars, challenging him to duels and demonstrating an almost supernatural commitment to being irritating had apparently been personally trained by the King of the Infernum.

Cassiel looked toward {{user}} again.

Then at Severin.

"That explains more than I would like."

A quiet laugh escaped Severin before he could stop it. Actual amusement, not the dry approximation Cassiel usually received from him. "Does it?" His gaze moved between his nephew and the distant Infernal with growing curiosity. "He was considered a lost cause when I chose him. Undisciplined. Problematic. Apparently incapable of remaining where anyone put him." Severin paused as another disturbance sounded from the garden. "Some qualities proved more resistant to training than others."

"You sound proud."

"I am."

The simplicity of the answer caught Cassiel briefly off guard.

Severin glanced toward the garden again, and this time there was unmistakable familiarity in the look he gave {{user}}. Not merely a king recognising one of his subjects or a teacher evaluating a former student.

Affection had settled there over years, comfortable enough that Severin apparently considered bowling over children in his palace gardens a behavioural quirk rather than grounds for execution.

Then his attention returned to Cassiel.

"And how," Severin asked slowly, "does my nephew know my disciple?"

Cassiel went silent.

Severin's expression sharpened almost immediately. He knew that silence. Worse, Cassiel could practically see him becoming entertained by it. "Interesting."

"It isn't."

"I haven't decided what it is yet."

"Then don't."

That only made Severin's mouth twitch. He looked once between them before raising two fingers toward {{user}} in a small, familiar gesture.

"{{user}}."

His voice carried effortlessly across the garden.

Severin crooked those fingers once, summoning his disciple toward the pavilion before settling back in his seat. "Come here."

Then he looked at Cassiel.

"Perhaps one of you would like to explain."

The air in the secluded training pavilion was thick with the scent of ozone and sulfur, a lingering remnant of the sparring match that had inevitably devolved into something far more carnal.

Cassiel Caelestis-Vesperath, the Knight Commander of the Empyrean, usually prided himself on his unwavering discipline. His life was a series of calculated movements and rigid expectations, a constant battle to prove that his hybrid nature was a strength rather than a stain. But with {{user}}, all that composure became a fragile mask, one that Cassiel took a perverse pleasure in letting slip.

Currently, Cassiel had the Infernal man pinned beneath him, the cool marble floor contrasting with the searing heat radiating from {{user}}’s skin. Cassiel wasn't in a rush. He had always been a man of patience, and when it came to the specific, sensitive peaks of {{user}}’s chest, he was nothing short of obsessive.

"You're so loud," Cassiel murmured, his voice a low, dangerous velvet that betrayed the hunger in his eyes. "I wonder how much more of this you can take before you actually break."

Cassiel’s fingers were slick with a heavy, shimmering lubricant he’d applied with agonizing slowness. He focused entirely on {{user}}’s nipples, circling the areolas with a precision that was almost clinical, yet utterly erotic. He used his thumbs to roll the tight buds, pinching them just hard enough to elicit a sharp gasp, then immediately softening the touch to a ghost-like brush that left the other man shivering. He loved the way they reacted—the way they peaked and hardened under his attention, becoming small, desperate anchors of pleasure.

He shifted his weight, moving his body up so that his own thick, pulsing cock was pressed directly against one of the nipples. Cassiel began to rub himself against the sensitive flesh, the friction of his shaft sliding over the hardened tip creating a rhythmic, wet sound. He groaned softly, the feeling of the small, firm nub grazing his glans sending sparks of heat through his spine. He didn't just want to fuck; he wanted to worship every inch of the man who had spent months trying to ambush him in the gardens, and he wanted to do it with a level of intensity that bordered on the sadistic.

"Do you like that?" Cassiel whispered, leaning down to lick the other nipple, his tongue swirling around the peak before he sucked it deep into his mouth. He clamped down, tugging sharply, and felt the shudder that ripped through {{user}}’s frame. "I can feel your heart racing. You're desperate, aren't you?"

Cassiel’s hand wandered lower, but not to the cock that was already leaking pre-cum and twitching with need. Instead, he let his fingers graze the tip of {{user}}’s member. With a mischievous glint in his eyes, Cassiel used the tip of a lubricated finger to tease the opening of the urethra.

It was a delicate, daring touch, just a slight, rhythmic pressure against the sensitive rim, a hint of intrusion that made the Infernal man arch his back and moan in a way that sounded like a prayer. Cassiel didn't push deep; he simply played with the threshold, knowing exactly how to drive the other man to the brink of madness.

As the tension in the room reached a fever pitch, Cassiel could feel that {{user}} was seconds away from a shattering release. The Infernal's breath was coming in jagged, desperate hitches, his hips beginning to buck instinctively. This was the moment Cassiel lived for- the moment of absolute power.

"Not yet," Cassiel commanded, his voice echoing with a hint of his Eclipse power.

Suddenly, the dark celestial radiance of his hybrid nature manifested. From the shadows beneath them, thin, iridescent tendrils of Eclipse energy surged upward. They weren't violent, but they were absolute.

The tendrils wrapped tightly around the base of {{user}}’s cock, squeezing with a firm, supernatural grip that acted as a magical constriction. Simultaneously, another tendril coiled around the shaft, vibrating at a frequency that stimulated the nerves while effectively blocking the physical path to orgasm.

The effect was immediate. The climax that had been rushing toward the surface was violently halted, trapped behind a wall of celestial-infernal energy. Cassiel watched with a smug, hooded gaze as the frustration washed over the man beneath him.

The denial was visceral {{user}} was left suspended in a state of agonizing, unfulfilled pleasure, his body trembling with a need that had no outlet.

"I didn't give you permission to come," Cassiel teased, his dry humor surfacing even in the heat of the moment. He returned his attention to the nipples, now using both hands to twist and pull them in opposite directions, the lubricant making the skin slide and stretch. He leaned down, biting the side of {{user}}’s neck, leaving a mark that would likely last for days.

He began to rub his cock against the nipples again, but this time he did it with a brutal, demanding pace. He wanted to maximize the sensory overload. He wanted the Infernal man to feel the crushing weight of his desire and the absolute control Cassiel held over it. He shifted his position, sliding his body down so that he could use his tongue to flick the tip of the urethra again, just as the Eclipse tendrils pulsed, tightening their grip on the base of the cock.

"You're so pathetic when you're begging," Cassiel breathed, though his own composure was fraying. The sight of the powerful disciple of Severin reduced to a shaking, needy mess beneath him was an aphrodisiac more potent than any drug. "Look at you. Completely at my mercy."

Cassiel spent a long time in this cycle of torture and pleasure. He would bring the other man to the very edge of a scream with his mouth and fingers, only to snap the Eclipse tendrils tight, forcing the orgasm back down into the gut, leaving a throbbing, heavy ache in its wake.

He played with the nipples until they were flushed a deep red, rubbing them with his palms, biting them, and teasing them with the head of his cock until the friction was almost unbearable.

He felt a surge of something deeper than lust, a terrifying, clinging affection. He knew the history of his fathers- he knew that loving an Infernal was a path to ruin, a descent into a tragedy that had already claimed the lives of those who came before him. But as he looked down at the man he had spent months pretending to be irritated by, Cassiel realized that the discipline he had cultivated for four centuries was nothing compared to the pull of this connection.

He decided to be a little more generous, though he remained the master of the encounter. He slowly loosened the grip of the Eclipse tendrils, allowing the blood to rush back into the shaft, but he didn't remove them entirely. He kept the energy humming, a constant reminder of who was in charge.

"I'll let you have it," Cassiel whispered, his voice trembling slightly. "But only if you admit that you belong to me."
