Shortened summary for non smut fans: Jin and Rui had snu snu.
---------------------------
Jin stepped back as the words came out of Rui's mouth.
Her words were so direct and honest that they sent heat through his body.
He'd never imagined someone could want him this way, especially not this beautiful, chaotic demon who had crashed into his ordered life.
He took her hands in his, bringing them to his lips gently.
"I never expected this," he whispered against her skin.
"Any of this."
His voice trembled slightly as he continued,
"I spent my life in discipline and devotion. I never thought I'd fall in love."
"Especially not with a demon princess."
"I was taught that desire leads to suffering. That attachment is the root of all pain." His thumb traced circles on her wrist.
"But I am still a man, Rui. And I desire you in ways that terrify me."
He guided her backward until they reached the thin mattress on the floor. Jin's weight pressed her gently into the bedding.
Rui removed the fastenings of her robes, loosening them enough to create an opening.
She took his hand and guided it inside, placing Jin's palm against her bare skin, touching the soft swell of her breast.
He brushed his thumbs across her nipple, feeling it harden beneath his touch.
"Is this okay?" he whispered, his voice rough with desire.
Rui answered by arching into his touch, a soft sound escaping her lips that made Jin's control slip further away.
Jin's lips left hers to trace a burning path down her neck. His kisses were careful initially, then grew bolder as her soft sighs encouraged him.
He found a sensitive spot where her neck met her shoulder and lingered there, feeling her pulse race beneath his tongue.
Then, he peeled away her robes completely.
As Rui lay bare before him, Jin paused to take in the sight of her—the princess of the underworld, vulnerable and wanting beneath him.
"You're driving me insane," he whispered, lowering his head to her breast.
His lips closed around her nipple, drawing it into his mouth with gentle suction that made Rui gasp and arch her back.
His hand found her other breast, fingers circling and teasing the sensitive peak.
"Jin," she breathed, her hands moving to his robes.
"Let me see you too."
She helped remove his clothing. Her hands explored the lean muscles of his chest and traced the contours of his abdomen, honed from years of physical discipline.
Then she moved lower and wrapped her fingers around his hardened length.
"Rui..!" Jin gasped at her touch.
Her hands moved up and down his shaft in rhythmic motion.
"Is this—am I doing this right?" she asked, a rare moment of uncertainty in her voice.
Jin couldn't form words, only managing a nod as his face blushed more intensely.
His hand covered hers, showing her how to move, and his other hand slid down her body, between her thighs.
He found her slick with desire, and the discovery sent a surge of pride through him.
Carefully, he moved his fingers inside her warmth, watching her face as pleasure transformed her features.
"Rui," he whispered, his voice thick with need.
"Tell me what you want."
Rui looked up at him, her blue eyes dark with desire.
"I want you," she whispered, her voice stripped of its usual playfulness.
"All of you, Jin. The monk, the man, everything."
Jin positioned himself above her, his hardness pressing against her entrance. The sensation made them both gasp.
He rubbed himself against her slick folds, the friction sending waves of pleasure through them both.
"I've never..." he began, his voice trailing off as embarrassment colored his cheeks.
"Neither have I," Rui admitted softly.
Jin's eyes widened in surprise. "But you're—"
"An immortal demon?" She smiled, a hint of vulnerability in her expression.
"Truth is, I've never wanted someone like this…"
Her words sent a surge of possessive heat through Jin's body.
He positioned himself at her entrance again, more deliberately this time.
"Are you sure?" he asked, his voice strained with the effort of holding back.
Rui answered by wrapping her legs around his waist and pulling him closer.
Jin pushed forward slowly, feeling her body yield to him inch by inch.
Rui's back arched, a moan escaping her lips that Jin quickly silenced with his mouth.
He swallowed her sounds, feeling her fingernails dig into his shoulders as he seated himself fully inside her.
"You feel so tight."
Jin stayed still for a moment, letting her adjust to the sensation.
Then, he moved slowly, watching her face for discomfort.
But there was only pleasure in her expression, her eyes half-closed, lips parted.
Then, as if something primal awakened in him, his pace quickened as his hands pinned her wrists above her head.
The prayer beads around his wrist glowed faintly red as he claimed her with increasing urgency.
With surprising strength, he gripped her shoulders and turned her around, guiding her onto her hands and knees.
"You enjoyed it, didn't you?" His voice was low and dangerous. "Making me jealous today."
Rui glanced over her shoulder, a mischievous smile playing on her lips despite her vulnerable position.
"I have no idea what you're talking about."
His hand slid up to tangle in her hair, gently pulling her head back.
"The way you touched that monk's arm and that smile you gave him." His free hand skimmed down her side, gripping her hip.
"You knew I was watching."
"Maybe," she breathed, arching her back slightly.
"Or maybe I just enjoy attention."
"Well, you have mine now," Jin growled, positioning himself behind her.
"All of it."
He leaned forward, his chest pressing against her back as he whispered in her ear,
"I never thought I'd be a jealous man. But with you..." His grip on her hip tightened.
Jin entered her with one powerful thrust, drawing a surprised gasp from her lips.
"Ahhh…!"
The sensation was overwhelming—fuller, deeper than before.
"Is this what you want?" he asked, his voice strained with restraint.
"Don't stop," she moaned.
He began to move again, each thrust more forceful than the last. His hands held onto her hips, pulling her back deeper with each thrust.
Rui trembled as pleasure coursed within her. Each movement sent waves of sensation coursing through her body.
She bit her lip to keep from crying out, but an intense thrust broke her resolve.
"Jin!" she cried, echoing in the small room.
Jin's hand quickly moved to cover her mouth, his chest pressed against her back as he continued his relentless pace.
"Quiet," he murmured against her ear.
"Unless you want the entire temple to hear how a princess sounds when she's being taken."
The possessiveness in his voice only heightened her pleasure.
She moaned against his palm, the sound muffled but unmistakable.
Jin's other hand slid around to the front of her body, finding the sensitive bundle of nerves between her thighs.
His fingers circled in rhythm with his thrusts, driving her closer to the edge.
"This is what happens," he growled softly, "when you make me jealous."
Jin's movements grew more urgent, his breath coming in short gasps against Rui's neck.
His fingers worked between her thighs, circling and pressing with increasing pressure as his hips maintained their relentless rhythm.
"Let go, Rui," he whispered, his voice rough with desire.
His words pushed her over the edge. Rui's body tensed, then shuddered violently as waves of pleasure crashed through her.
Her cry of release muffling against Jin's palm, her inner muscles clenching around him in pulsating waves.
The sensation of her climax triggered Jin's own.
With a final powerful thrust, he pinned her to the ground beneath him, his larger frame covering hers completely as he buried himself deep inside her.
A guttural groan escaped his throat as his release claimed him, his body shuddering against hers.
They remained frozen in that position for several moments, their hearts racing and their bodies trembling.
As their breathing gradually slowed. Jin reached for the thin blanket at the foot of the bed and pulled it over their bare bodies.
Rui turned in his arms to face him, her blue eyes searching his.
"What are you thinking?" she whispered, her fingers tracing patterns on his chest.
Jin's eyes softened as he gazed at her. He kissed her forehead tenderly, letting his lips linger there.
"I'm thinking that you are the worst thing that has ever happened to me," he said softly.
A smile curved Rui's lips. "Worst? Is that a complaint?"
"No," he said, his voice growing serious.
"It's gratitude."
"Sometimes I wish we could just run away together. Find some quiet corner of the world where you're not a demon princess and I'm not a vessel for an ancient beast."
Rui's expression softened. "Where would we go?"
"Maybe, somewhere by the ocean," Jin mused. "I've always wanted to see it.
"We could build a small house on a cliff overlooking the waves and live a simple life.
His smile turned sad. "But I know it's not possible for us. You have your trials to complete, your kingdom to return to. And I..."
He glanced at the prayer beads lying discarded on the floor.
"I have my burden to bear."
Rui opened her mouth to respond, but the sudden footsteps outside the door silenced her.
They froze, eyes wide with alarm.
