Chapter Sixteen
“You’ve been holding back.”
Julian’s observation came as Cillian lowered him onto the bed, shadows already sliding beneath his shirt. Not a question. Never a question with his beacon. Julian saw things, noted them, and commented on them as an absolute truth.
“Yes.” There was no point lying. Cillian had been holding himself back since that first night, careful not to overwhelm his mate, cautious with his strength and his hunger. “You deserve…”
“I deserve honesty.” Julian pulled him down, fingers threading through Cillian’s hair. “I’ve read enough to understand what a claim actually entails. You’ve been a gentleman up till now, something I didn’t expect, and I do appreciate it, but you need to stop treating me as if I’m fragile.”
Cillian’s shadows writhed, responding to Julian’s words like a physical touch. “You’re mortal.”
“And you won’t hurt me.” Julian tugged him closer, close enough that Cillian could feel the heat radiating from his skin and taste the confidence in his scent. “Show me what you actually want. All of it. That’s what I want.”
Cillian couldn’t deny Julian anything. His shadows surged forward, stripping Julian’s clothes.
Fabric tore. Julian gasped, not in fear but in anticipation, his pupils dilating as Cillian’s true nature manifested around them.
The darkness pooled across the bed, wrapping around Julian’s wrists and ankles, spreading him open.
“Tell me if it’s too much.” Cillian’s voice had dropped into octaves that would make lesser beings flee. His human form rippled, unable to maintain full cohesion when his mate had aroused him to the point of pain.
“It won’t be.” Julian tugged against the shadows holding his wrists. They wouldn’t yield, and for some reason, that made Julian smile. “You’re stalling.”
After seeing everything in life and more beyond, his infuriating, brilliant human still managed to surprise him.
Cillian shed his own clothes, letting his form blur further.
He wasn’t his fully void-shape, but no one looking at him could call him human.
His skin absorbed light. His eyes multiplied.
The shadows extending from his body became indistinguishable from the ones pinning Julian to the bed.
Julian’s breath caught, but his gaze remained steady. Cataloging. Always cataloging. “Fascinating,” he murmured.
Something in Cillian’s chest cracked open.
He descended on Julian like a storm, claiming his mouth with enough force to bruise.
Julian opened for him immediately, tongue meeting Cillian’s with equal aggression.
No hesitation. Just raw want that burned through their bond until Cillian couldn’t tell where his hunger ended and Julian’s began.
The shadows caressed every inch of exposed skin, mapping territory they’d been desperate to claim.
Wrapping around Julian’s throat - not squeezing, just present - a constant pressure that made Julian arch into it.
They slid across his chest, circling his nipples until he groaned into Cillian’s mouth, while still more tendrils spread along Julian’s inner thighs, holding him open.
“You have too many of them,” Julian panted when Cillian released his mouth to bite down on his neck. “I can’t…can’t track…”
“Don’t track. Feel.”
Cillian punctuated the command with a tendril curling around Julian’s cock, stroking with the same rhythm as the shadow teasing his entrance.
It was clear Julian’s analytical mind tried to catalog the sensations for approximately three seconds before surrendering.
His head fell back, throat bared in unconscious submission that made every possessive instinct in Cillian howl with satisfaction.
“Mine.” The word came out layered, echoing from the void. Cillian sealed it against Julian’s collarbone with teeth, tasting salt and something sweeter - the essence of a beacon, bright enough to burn. “Say it.”
“Yours.” Julian rolled his hips, seeking more friction. “But that makes you mine too.”
“Yes.” Cillian moved lower, shadows maintaining their relentless exploration while his mouth traced Julian’s ribs, his hipbones, the junction of thigh and groin. “Always. From the moment you looked at me and didn’t run.”
He closed his mouth around Julian’s cock without warning, swallowing him down while shadows pressed inside simultaneously. Julian’s shout echoed off the walls. His body went rigid, every muscle locked in shock at the dual sensation.
“Too much?” Cillian pulled back just enough to speak, his shadows still moving.
“Don’t you dare stop.”
Cillian resumed his assault with renewed intensity.
His shadows had memorized Julian’s responses during their first encounter and knew exactly where to press, how much pressure made him gasp versus moan.
But this time it was different. Cillian was claiming his beacon.
Every touch carried intent, marking Julian from the inside out until nothing existed except their bond.
The shadows stretched Julian’s ass open while Cillian worked his cock, adding teeth just carefully enough to make Julian curse.
More tendrils wrapped around Julian’s thighs, his waist, his throat, anchoring him in every way.
A reminder that Julian - their beacon - now belonged to an ancient being who was both hungry and utterly devoted.
“Cillian.” His name in Julian’s mouth sounded like a prayer and demand simultaneously. “Please.”
“Please, what?” Cillian released him, moving up his body like a predator. The shadows inside Julian withdrew, replaced by Cillian’s heavy cock. He positioned himself at Julian’s entrance, with a blunt pressure that made them both groan. “Tell me.”
“Claim me.” Julian’s hands flexed in the shadows’ grip, eyes fever-bright. “Properly. The way you’ve wanted to since the alley.”
Cillian pushed forward in one devastating thrust, confident the shadows would’ve slicked his way.
Julian’s back bowed, a broken sound escaping his throat that lived somewhere between pain and pleasure.
It could’ve been too much, and maybe it was too fast, but Julian had demanded honesty, and this was Cillian’s first time.
He had an eternity’s worth of hunger pouring into this moment - the most intimate of connections.
The shadows tightened everywhere they touched, creating a web of sensation that made it impossible to separate one feeling from another.
“Breathe,” Cillian ordered, holding still despite every instinct screaming to move. “Julian. Breathe.”
Julian dragged in air, eyes finding Cillian’s multiple ones without flinching. “Move.”
“You need…”
“I need you to stop treating me like I’ll break and fuck me the way you want to.”
The crude language from his proper archivist destroyed the last of Cillian’s restraint.
He withdrew almost completely and slammed back in, setting a brutal pace that would have shattered a normal human.
But Julian was a beacon, and the mate bond was already weaving between them, strengthening Julian’s body to withstand a guardian claiming.
More. Deeper. Harder. The shadows joined the rhythm, stroking and pressing and wrapping until Julian existed in a constant state of overwhelm. Every nerve ending fired simultaneously. Every sense consumed by darkness and heat and the unyielding presence of his mate.
Cillian felt it through their bond - the moment when Julian’s mind finally went blissfully silent. No analysis. No processing. Just pure sensation, reducing him to gasps, moans, and increasing profanity.
“Perfect.” Cillian angled his hips, found the spot that made Julian scream. Once found, he hit it again and again. The shadows around Julian’s cock tightened, matching the pace of Cillian’s thrusts. “Look at you. Taking everything I give you.”
“More,” Julian demanded, coherent thought already dissolving. “Want…need…more.”
“I know what you need.” Cillian leaned down, careful not to crush him despite the feral urge to cover Julian completely. Their foreheads touched. “Can you feel it? The bond flowing through your whole body?”
Julian nodded, unable to form words. Cillian could feel it too - threads of light and shadow weaving between them, as permanent as DNA.
The claiming would leave marks. Not visible ones, necessarily, but Julian would carry Cillian’s essence in his cells, his blood, his soul.
And Cillian would burn with Julian’s brightness until the stars went cold.
“Come for me,” Cillian commanded, shadows, voice, and bond all amplifying the order. “Let me feel you.”
Julian shattered. His release hit like a supernova through their connection, pleasure so intense it bordered on pain.
Cillian felt every second of it - the muscle contractions, the spike of endorphins, the way Julian’s mind went white with ecstasy.
It triggered his own climax that hit him with the force of a truck.
Cillian buried himself as deep as possible into his mate and let go. The shadows pulsed with each wave, marking Julian inside and out. The bond blazed between them, sealing them together permanently in a way nothing could break.
Julian’s voice gave out halfway through his second orgasm. He collapsed boneless against the bed, his chest heaving, skin flushed and marked with shadows that wouldn’t fade for hours.
Cillian carefully withdrew, immediately gathering Julian against his chest despite the sticky aftermath.
His shadows gentled, morphing from possessive claim to protective cocoon.
Julian’s heartbeat thundered against Cillian’s ribs - too fast, but already beginning to synchronize with his own supernatural rhythm.
“Still breathing?” Cillian managed, voice hoarse.
“Barely.” Julian’s fingers traced lazy patterns on Cillian’s shoulder, the only movement he seemed capable of. “That was...”
“Too much?”
“Perfect.” Julian tilted his head up, exhausted but smiling. “Though I may need a few minutes before we do it again.”
Cillian laughed, not the rusty, restrained laugh of old, but full, rich, buoyant laughter, so foreign the sound startled him. When had he last laughed like that? “You’re insatiable.”
“You literally just claimed me with shadow tentacles. I think you’ve forfeited the right to call me insatiable.”
“Fair.” Cillian’s shadows retrieved a blanket, tucking it around them both. His human form was reasserting itself now that the immediate claiming frenzy had passed, but threads of darkness still connected them at multiple points. “How do you feel?”
Julian considered, ever analytical, even in the aftermath. “Different. Like there’s a frequency I can hear now that didn’t exist before. Is that the bond?”
“Yes. You’ll feel my emotions as echoes. Physical sensations sometimes, in moments of extremity.” Cillian pressed a kiss to Julian’s temple. “And I’ll feel yours. We’re linked now in a way that can’t be undone.”
“Good.” There was no hesitation at all. Julian shifted closer, tucking his head under Cillian’s chin. “I don’t want it undone.”
The simple acceptance pierced through Cillian more effectively than any weapon. He tightened his hold, shadows curling protectively. His beacon. His mate. His.
“The marks will fade by morning,” Cillian murmured against Julian’s hair. “The internal ones are permanent.”
“I know. I read the literature.” Julian yawned. “Thoroughly.”
“Of course you did.”
“Though the literature failed to mention the shadows would be quite so...” Julian trailed off, searching for the word.
“Enthusiastic?”
“Everywhere.”
“They’re part of me. They wanted you just as desperately.” Cillian ran his hand down Julian’s spine, satisfaction pooling warm in his chest. “Do you understand now? Why I’ve been holding back?”
“Yes. And I’m demanding you stop.” Julian’s voice was already drowsy, exhaustion finally catching up. “No more restraint. Not with me.”
“As you wish.”
Julian’s breathing evened out within minutes, the bond allowing Cillian to feel the exact moment he slipped into sleep.
The trust implicit in that simple action - falling unconscious while still covered in a guardian’s shadows, claimed, marked, and completely vulnerable - caused something fierce and protective to surge through Cillian’s ancient soul.
His shadows spread through the room, weaving additional defenses while Julian slept.
The mate bond pulsed between them with each heartbeat, a rhythm Cillian had never expected to experience.
He cataloged every detail - Julian’s warmth, his weight, the small movements he made even in sleep and the faint smile on his face.
Cillian had never understood what it meant to be complete until a too-honest archivist looked at a monster and saw something worth keeping. He pressed another kiss to Julian’s temple, his shadows curling around them both. Mine, he thought, and felt the bond hum in agreement.
