Work Text:
The heavy oak doors of the Lee ancestral mansion slammed shut behind Jake with a finality that made his stomach drop. Rain lashed against the tall windows, thunder rumbling in the distance like an omen. His wedding suit still clung damply to his skin from the short walk from the car. The ceremony had been small, almost secretive — just the two families and a priest who refused to meet anyone’s eyes.
Sim Jaeyun, now legally Lee Jaeyun, was twenty-three and already sold.
His father’s debts, the failing company, the whispers of curses plaguing the Sim bloodline… all of it wiped clean in exchange for this marriage. The Lee family had demanded it. And the Lee family always got what they wanted.
A tall figure descended the grand staircase, candlelight flickering across sharp cheekbones and dark eyes.
Heeseung.
He was taller than Jake remembered from the single awkward meeting two weeks ago. Dressed in all black, the top buttons of his shirt undone, he moved with unnatural grace. His presence seemed to swallow the light around him.
“Jaeyun,” Heeseung said, voice low and smooth. It sent an involuntary shiver down Jake’s spine. “Welcome home.”
Jake swallowed. “This is temporary, right? Until the contracts are fulfilled—”
Heeseung’s lips curved into something that wasn’t quite a smile. “There is no temporary in this house. You belong to me now. Body and soul. The papers made sure of that.”
He stepped closer, lifting Jake’s chin with two cold fingers. Jake’s heart hammered so loudly he was sure Heeseung could hear it.
“Come. Let me show you to our room.”
The walk upstairs felt endless. Portraits of long-dead Lees lined the walls, their eyes seeming to follow every step. Some of the paintings had faces that looked too much like Heeseung — same sharp jaw, same piercing gaze, even though the dates beneath them went back centuries.
The master bedroom was massive, dominated by a four-poster bed draped in deep crimson velvet. A fire crackled in the hearth, but the room still felt ice-cold.
Heeseung closed the door behind them. The click of the lock echoed.
“You’re shaking,” Heeseung observed, almost gently. He removed his cufflinks with deliberate slowness. “Are you afraid of me, wife?”
Jake’s cheeks burned at the word. “I’m not your wife.”“You are. In every way that matters.” Heeseung crossed the room in three strides and pulled Jake against his chest. One hand splayed possessively across his lower back. “And tonight, I intend to consummate this marriage properly.”
Jake tried to push him away, but Heeseung’s grip was iron. “Wait— I barely know you. This is insane—”
“You know enough.” Heeseung’s breath ghosted over Jake’s ear. “You know your family sold you to save themselves. You know I could have chosen anyone, yet I chose you. The moment I saw your photo, I knew.”
“Knew what?” Jake whispered.
“That you would taste sweet when you’re terrified.”
Before Jake could process the words, Heeseung kissed him. It wasn’t gentle. It was hungry, devouring — tongue pushing past his lips, claiming every inch of his mouth. Jake gasped, and Heeseung drank the sound like fine wine. A faint metallic tang bloomed on Jake’s tongue. Blood. Heeseung had bitten his lip.
The older man groaned softly, sucking on the small wound. His eyes seemed to glow faintly red in the firelight.
“What the hell are you?” Jake breathed when they parted.
Heeseung smiled, fangs glinting. “Your husband.”
He pushed Jake onto the bed, climbing over him with predatory grace. Clothes were removed with frightening efficiency — Jake’s shirt ripped open, buttons scattering across the floor. Heeseung’s mouth latched onto his neck, sucking hard enough to leave dark marks while his hands roamed lower.
“Stop fighting it,” Heeseung murmured against his collarbone. “Your body already knows who it belongs to.”
Jake hated how true it felt. Every touch sent electricity racing through him. Fear twisted sickeningly with arousal. When Heeseung’s cool fingers wrapped around his cock, stroking with perfect pressure, Jake couldn’t hold back a broken moan.
“Hyung… fuck—”
“That’s better.” Heeseung’s voice had dropped an octave. He worked Jake open with slick fingers, patient but relentless, curling them just right until Jake was writhing and begging. Three fingers deep, stretching him, scissoring, brushing that spot again and again until tears pricked Jake’s eyes.
When Heeseung finally pushed inside, Jake saw stars. The stretch burned deliciously. Heeseung was big, thick, and he didn’t stop until he was buried to the hilt. He stayed there, hips flush, letting Jake adjust while kissing the tears from his cheeks with surprising tenderness.
“Mine,” Heeseung growled. “Say it.”
“Yours—” Jake choked out.
The pace started slow, deep rolls of hips that made Jake feel every inch. Then harder. Faster. The heavy bedframe slammed against the wall in rhythm with Heeseung’s thrusts. Jake’s nails dug into Heeseung’s back, drawing blood. The sight of red streaks on pale skin seemed to drive Heeseung wild. He licked a stripe up Jake’s neck and bit down — not enough to kill, but enough to drink.
The pain mixed with pleasure sent Jake spiraling. He came untouched, spilling between their stomachs with a cry. Heeseung followed soon after, burying himself deep and filling Jake with hot release, whispering filthy praises against his ear.
They lay tangled afterward, Heeseung still inside him, arms wrapped around Jake like steel bands.
“You can never leave,” Heeseung said quietly, almost sadly. “The blood oath in our marriage contract… it binds you to this house. To me. If you try to run, the shadows will bring you back. Every time.”
Jake’s heart stuttered. “What?”
Heeseung traced a finger over the fresh bite on Jake’s neck. “My family isn’t human, Jaeyun. Not fully. We made a deal with something ancient centuries ago. Eternal life in exchange for… offerings. You are my offering. And my salvation.”
Jake should have felt pure terror. Instead, a strange warmth bloomed in his chest. He was trapped, yes. But for the first time in years, someone wanted him — desperately, obsessively.
Days blurred into weeks inside the mansion.
Jake explored during daylight when Heeseung slept. He found locked rooms, ancient journals written in fading ink, portraits where Heeseung appeared unchanged across two hundred years. At night, Heeseung claimed him again and again — sometimes gentle, sometimes feral against the library shelves or in the moonlit garden where roses bled red petals.
One stormy evening, Jake tried to run.
He made it as far as the iron gates before the shadows moved. Dark tendrils coiled around his ankles, whispering in Heeseung’s voice. They dragged him back gently but firmly, depositing him at Heeseung’s feet in the foyer.
Heeseung looked disappointed. And hungry.
He punished Jake that night with slow, torturous edging until Jake was sobbing and incoherent, promising he’d never leave again. Only then did Heeseung let him come, fucking him through orgasm after orgasm until Jake passed out from exhaustion.
In the afterglow, Heeseung held him close, stroking his hair.
“I don’t want to break you,” he whispered. “I want you to love me. Even if it takes decades. Even if I have to keep you here forever.” Jake, sore and marked and strangely content, turned in his arms and kissed the corner of Heeseung’s mouth.
“Maybe I already do.”
The mansion groaned around them, as if approving. Outside, the forest whispered secrets. Inside, Heeseung smiled against Jake’s skin, fangs grazing tenderly over the pulse point that now beat only for him.
Their arranged marriage had become something far darker. And neither of them would ever be alone again.
