The air in the church was thick with incense and silence.
It clung to the back of your throat, warm and heavy, as you stepped into the old confessional.
You werenât religious. You never had been.
But every week, like clockwork, you came to him.
Father Kai.
He never called you by name.
Never touched you.
But his voiceâlow, velvety, laced with something that didnât belong in a house of Godâslid through the grate and made your thighs press together in guilt and want.
You knelt.
The candlelight flickered. And then you heard it: the familiar click of the door across from you.
He was here.
The quiet creak of leather gloves as he shifted. The faint scent of clove and spice.
Your heart stuttered.
âForgive me, Father,â you breathed, head bowed.
âIâve sinned again.â
A pause. Long enough to make your stomach twist.
Then his voice cameâcalm, cold, and cruelly patient.
âThen kneel pretty,â he said, âand tell me all about it.â
You shifted on your knees, the hard wood beneath you biting into skin, but you didnât care. You never did.
Not when you knew he was on the other side of the screen.
The air between you sparked with staticâhis breath quiet, measured, too calm for what he had to know you were feeling.
âWhat is it this time?â he asked, voice smooth as velvet.
âAnother man?â
A pause.
âA thought you shouldnât have entertained?â
You exhaled, lips parted, your voice barely a whisper.
âNo. Just one man.â
The silence crackled. You could practically feel his restraint.
âI see.â
You dared to shift againâjust a littleâthighs pressing together in a way you hoped he could hear. You knew it was wrong. That was the point.
You wanted him to feel it too.
âI wore the dress you hate,â you confessed.
âThe one that rides up when I kneel.â
The edge in his breath told you everything.
âIâm not here to play with you,â he murmured, but his tone betrayed himâdeep and frayed and strained.
You smiled, wicked and soft.
âYou never are.â
Another long pause. This one felt like it stretched miles.
âYou came here to be punished,â he said. Not a questionâjust a fact.
You bit your bottom lip and nodded even though he couldnât see.
âSay it.â
âI came here to be punished, Father.â
He hummed lowâalmost pleased. It made your stomach flutter and twist with anticipation.
âI should make you pray,â he said.
âOut loud. On your knees. Until your throat is raw and you regret ever teasing me with that little f*cking dress.â
Your breath hitched. Your spine straightened.
âBut I wonât,â he continued, voice laced with mercy dipped in sin.
âBecause I like the way you break without me having to touch you.â
You clenched your fists, thighs aching, and whisperedâ
âPlease.â
He chuckled, low and dangerous.
âIâll tell you when itâs time to beg.â
The confessional creaked with every shift of your weight, the candlelight beyond the lattice flickering like it could sense something unholy about to take place.
You breathed in the scent of himâclove, musk, aged wood, and something sharper. You wondered if his hands were in fists. If he was gripping the edges of the bench to keep from doing what he really wanted.
âI touch myself when I think of you,â you said softly.
There was a pause so long you thought he might have walked out.
Thenâ
âSay that again.â
Your breath caught.
âI said⌠I touch myself when I think of you, Father.â
A low exhale. You felt it more than heard it.
âWhere?â
The question was a growlâquiet, dangerous, fraying at the seams.
Your heart pounded. Your voice, barely a breath.
âMy thighs. My chest. MyâŚâ
You hesitated, and he cut in.
âSay it.â
âMy p*ssy,â you whispered.
The sound of leather shifting. A low, ragged inhale.
âYou are testing me little one,â he muttered darkly. âYou want to see what it takes to make me fall.â
And you did.
You wanted to see what Kai Mori looked like when he finally gave in.
âI want you to break your vows,â you said. âFor me.â
He didnât speak for a long time. Just the beat of your breath. The throb between your legs. The fire building.
Thenâ
The booth door creaked open. Heavy footsteps.
Your door snapped open.
And there he stood.
No mask. No collar. Just a man whoâd spent too long pretending not to want what he did.
âYou want to sin?â he asked, voice low and raw.
He stepped in, pulled the door shut behind him, and backed you against the wall of the booth. His eyes were black in the candlelight, jaw tight, breath ragged.
âThen kneel, pretty girl.â
You sank, heart hammering.
And when his fingers tangled in your hair, guiding your mouth where heâd been dreaming of it every night since you started coming here, he whispered it againâ
âOnly for me.â
The candlelight outside flickered like it knewâlike it blessed what was happening behind the boothâs carved door.
You were already on your knees. You knew what you looked like from down thereâeyes wide, lips parted, desperate.
Kai stood over you, quiet, composed⌠until he wasnât.
âIâve dreamed about this,â he muttered, his voice wrecked. âYou on your knees in a church. Not praying. Just mine.â
He stroked a finger across your bottom lip, watching it drag and catch.
âOpen.â
You didâobedient, aching.
He slid his thumb inside your mouth, pressing down on your tongue.
âGood girl,â he breathed, and you swore you saw his composure fracture right then and there.
âI should feel ashamed,â he muttered, âbut all I can think about is how fucking perfect you look like this.â
You whimpered, and he pulled his thumb out slowly, then traced your cheek with the back of his hand.
âSuch a pretty little thing,â he whispered. âAlways testing me. Always looking at me like you want me to ruin you.â
Your breath hitched. âMaybe I do.â
His jaw clenched. His hand tangled in your hair.
âThen take what you asked for, little one.â
And he gave it to youâraw and reverent, slow at first, careful, like this was still sacred somehow. His hips rolled forward, controlled but needy, as your mouth welcomed him inâlike a confession.
He didnât stop talking. Whispering filth against your temple, praises laced with sin.
âYou look so good like this.â
âIs this what you came here for, little one?â
âYou taste like salvation. F*ck.â
You hollowed your cheeks, eyes locked on hisâwatching him fall from grace with every quiet moan he tried to bite back.
âKai,â you gasped when he pulled you up, needing more, his restraint crumbling.
He backed you against the booth wall, one hand slipping up your thigh, fingers dragging through the mess between your legs.
âGod wonât hear you here,â he murmured. âBut I will.â
His mouth was on yours, tongue claiming, teeth scraping. His other hand cupped your jaw, holding you still.
âIâll take your prayers now,â he said into your lips.
And he didâevery gasp, every whimper, every desperate cry of please, more, yes, Fatherâlike each one belonged to him.
Because they did.
The air in the confessional was thick with sweat and candle wax and himâhis breath still uneven, lips swollen, collar askew.
You were curled against his chest now, tucked beneath his arm on the worn pew bench, your body still humming from what heâd done to you.
Kaiâs fingers combed through your hair in lazy, reverent strokes, his other hand wrapped around your thigh like he wasnât ready to let go. Like he never would be.
âI shouldnât have done that,â he murmured, though his voice held no regretâjust that soft, ruined rasp like youâd finally undone the last of his edges.
You tilted your head up, eyes finding his in the warm dark.
âBut you did,â you whispered. âAnd Iâd let you do it again.â
His jaw twitched, his mouth ghosting over your temple. He didnât answerânot right away. Just pressed a slow kiss to your forehead, then your cheek, then your lips. Soft. Lingered. Possessive.
âYouâre not a sin,â he said finally. âYouâre a fucking test.â
You smiled, drunk on him, on the warmth, the quiet, the way he looked at you like you were the first thing heâd ever wanted for himself.
And then, even quieterâ
âMy little one.â
Your heart thudded. His hand squeezed your thigh just once before relaxing again.
âI canât go back now,â he said into your hair. âNot after this.â
You shifted closer, fingers sliding beneath his shirt, palm flat over his heartbeat.
âThen donât.â
The candles outside burned lower. The chapel beyond the booth stayed quiet. And in the shadows, wrapped up in his arms, you finally felt chosen.
Not saved.
But kept.
