The confessional booth was dark, only the faint glow of a candle through the lattice separating you from him. His voice—deep, steady, holy—always unraveled you more than it should.
“Go on,” Father Barnes murmured, his hand making the sign of the cross on his chest. “Tell me what weighs heavy on your soul.”
You swallowed, fingers twisting in your lap. “It’s you, Father.”
Silence. A pause so sharp you thought your heart might stop. Then the rasp of breath.
“You… dream of me?”
Your cheeks burned, your thighs pressing together under your skirt. “Every night. I think about your hands—how they’d feel on me. I can’t stop. I know it’s wrong. I know I’m supposed to be ashamed, but—”
The wooden screen creaked. He leaned close, his voice a low growl, nothing like the sermons he gave on Sundays. “You tempt me with your confessions, little sinner. Do you know what you’re asking for?”
Your breath hitched. “To be cleansed.”
The door to your side of the booth opened. He was there, looming in black, collar snug against his throat. For a moment he just stared, like he was fighting every vow he’d ever taken. Then his hand cupped your jaw, thumb pressing your lower lip until it parted.
“Open.”
You obeyed. He slid two fingers inside, slow and deliberate, his eyes dark as sin. You moaned around the intrusion, heat flooding you, shame and arousal twined until you couldn’t tell them apart.
“Filthy little lamb,” he hissed, pulling his fingers free to trace them down your chest, lingering at the swell of your breasts. “You come to me begging absolution but all you want is to be ruined.”
“Yes, Father,” you gasped, arching toward him.
He smiled—wolfish, dangerous. Then he bent, mouth hot and hungry on your neck, teeth scraping skin like he wanted to mark you for the devil himself. His hands pushed up your skirt, fingers finding the slick proof of your sins.
“You’re soaked,” he growled, plunging two fingers inside you without mercy. “Dripping for your priest. Tell me, lamb—does that feel holy?”
You sobbed his name, clutching at his cassock. The rhythm was relentless, his thumb circling your clit until you were trembling, thighs clamping around his hand.
When he finally dragged himself free, his hardness straining against the black fabric, he pressed the head of his cock against your slick folds and murmured, “This is your penance. Take every inch of me and maybe—maybe—I’ll forgive you.”
And you did, crying out as he filled you, every thrust a prayer you’d never dare say aloud.
The old wood of the booth groaned with each thrust, the tiny confessional barely containing the sound of sin. His hand was braced against the wall, the other tight around your throat, holding you in place while he split you open on him.
“Look at you,” Bucky rasped, sweat beading along his temple, collar skewed but still clinging to his throat. “Spread and begging in the house of God. You want forgiveness? You’ll earn it on my cock.”
Your moans echoed in the tiny chamber, each one swallowed by his mouth when he kissed you—rough, punishing, like a starving man. His tongue tangled with yours, tasting every sinful whimper.
When he pulled back, he dragged you up onto his lap, settling on the hard wooden bench with you astride him. The cassock pooled around his thighs, his cock buried deep inside you. “Ride me, lamb. Show me how badly you want salvation.”
Your hands clutched at his shoulders as you moved, rocking against him, his girth stretching you so good it nearly broke you. Every grind of your hips made him groan low, his lips at your ear.
“You feel that? That’s what you’ve been praying for at night, isn’t it?” His teeth caught your earlobe, sharp enough to sting. “Tell me. Tell your priest what a filthy girl you are.”
“I—” your voice cracked, body shaking as his hand slid down to spank your ass, hard enough to echo.
“Say it.”
“I’m filthy,” you gasped, bouncing harder, lost in the rhythm. “I’m your sinner.”
“Mine,” he growled, slamming up into you so deep you saw stars. “You don’t belong to God right now—you belong to me.”
Your climax hit sudden and brutal, your nails raking down his shoulders as your body seized around him. He held you there, buried to the hilt, groaning like he was the one being saved.
And then—he broke. His thrusts grew erratic, desperate. His forehead pressed to yours, breath ragged. “Fuck—gonna—” He didn’t finish the thought, just spilled inside you with a guttural groan, filling you so deep it left no question what he’d done.
Silence followed. Heavy. Sacred in its own way. He didn’t move, still inside you, still clutching you close. His chest heaved, his lips brushing your temple.
“God forgive me,” he whispered. But he didn’t let you go.
He should’ve left you there, trembling and wrecked in the booth. Should’ve pulled his robes back into order and begged for penance of his own. But instead, he dragged you out into the chapel, past the rows of pews, up the steps to the altar.
The cross loomed above, silent witness as Father Barnes lifted you onto the cloth-draped table where so many had knelt in reverence. His hands gripped your thighs, spreading you shamelessly.
“Lay back,” he ordered, voice shredded by desire. “You’ll take your prayers from here tonight.”
Your back hit the altar, breath shuddering, and before you could even answer, his mouth was on you—tongue lapping greedily, beard scraping your soft flesh. He feasted like a man starved, like communion itself had been rewritten to taste of you.
“Say it,” he groaned between wet strokes, eyes flicking up to yours. “Pray for me while I ruin you.”
Your fingers tightened in his hair, body arching. “Hail Mary—full of grace—” The words broke into a moan as he sucked your clit, relentless. “The Lord is with thee—ah—”
He growled against you, devouring every broken syllable, dragging the prayer out of you with his tongue and fingers until you sobbed it, gasping through the rhythm of faith and filth.
“Blessed art thou among women,” he mocked against your cunt, voice thick with blasphemy. “And blessed is the fruit of your—fuck—sweet little body.”
You shattered again, crying out his name louder than the prayer, and he rose—chin wet, eyes wild. His cock was out again in seconds, heavy and red, pressing against your entrance.
“Finish it,” he demanded, pushing inside you in one punishing thrust that stole your breath. “Finish your Hail Mary while I split you open.”
Tears burned hot down your temples as you clung to him, the words spilling brokenly between cries of pleasure: “Holy Mary—Mother of God—pray for us sinners—now and at the hour of our death—”
Each line was punctuated by his thrusts, deeper, harder, until your body was a trembling prayer itself.
When you reached the final words, he lost control completely, slamming into you with abandon, groaning like a man damned. His release tore through him as you clenched around him, your own climax crashing down like a hymn sung too loud.
The church was silent again when it was over—save for your ragged breathing, the creak of the altar beneath your bodies. His forehead pressed to yours, sweat dripping.
“You’ll be the death of me,” he whispered, voice wrecked and reverent all at once. “And I’ll go to hell smiling.”

It was supposed to be routine. Just another evening confession. But when you slid into the booth, heart hammering, you could feel it in the air—thicker, heavier. He didn’t even wait for your whisper this time. The little door creaked, and suddenly he was in your space, eyes burning, cassock hanging loose around him.
“You came back,” he murmured, almost a prayer in itself. “You should’ve stayed away.”
But his hands cupped your face like he couldn’t stop himself, thumbs brushing your lips. And when you kissed him, when you opened willingly, he groaned like a man finally surrendering to the devil he’d been running from.
This time, he didn’t bother with the pews. He led you straight to the altar again, but it wasn’t bare. A dozen candles burned, their wax dripping slow and thick. A rosary lay coiled neatly on the linen, waiting.
“On your knees,” he ordered softly.
You sank without hesitation, the hem of his cassock brushing your cheek as you looked up at him. His cock, already straining, filled your mouth the moment you parted your lips, heavy on your tongue. He kept the rosary in one hand, beads slipping through his fingers as his hips moved shallowly against your mouth.
“Say your prayers while you take me,” he demanded, voice ragged.
The beads brushed your face as you obeyed, muffled words slipping out around his length: “Hail Mary, full of grace—” He groaned, hand tightening in your hair.
When he pulled you off, slick running down your chin, he bent to lift you onto the altar again. This time, he looped the rosary around your wrists, binding them above your head as he slid into you with a brutal thrust.
“Holy Mary,” he hissed through gritted teeth, setting a punishing rhythm, “Mother of God—pray for us sinners.”
Your moans echoed with the prayer, body straining against the beads biting your skin. He bent low, mouth to your ear, each thrust punctuated with blasphemy.
“You’re my sinner,” he growled. “And this—” His hand pressed hard to your lower belly where he bottomed out inside you, making you cry out. “—this is the only kind of worship I’ll ever give again.”
You prayed louder, sobbing the words through pleasure that felt like punishment and reward all at once.
He came undone inside you again, spilling deep, his own voice breaking on the last line of your prayer: “Now and at the hour of our death—”
When he collapsed against you, still buried, still trembling, he kissed your bound hands like they were holy relics.
“I’ll burn for this,” he whispered, forehead pressed to yours. “But I’ll burn with you.”
The church was packed, pews filled with the dutiful. You sat in the third row, hands folded sweetly in your lap, the light from the stained glass spilling across your face like a benediction. But you weren’t alone.
Your boyfriend’s arm was draped around your shoulders, casual, protective. He whispered something during the hymn that made you smile, and that smile nearly broke Father Barnes in two.
From the pulpit, he tried to keep his eyes on the Gospel, but his voice caught, thick with something more than scripture. Each verse tasted bitter when he saw your head dip against another man’s shoulder. His hands clenched the Bible tight enough his knuckles went white.
When the final hymn ended and the congregation spilled into the bright Sunday air, Bucky caught you before you could follow the others out. His hand was firm on your wrist, disguised as pastoral kindness to anyone watching.
“Stay a moment, child,” he murmured, his voice calm in a way that masked the storm inside. “I need a word with you.”
Your boyfriend gave a nod, respectful of the priest, and left you there. Bucky didn’t speak again until his office door shut behind you, the lock clicking into place. The air grew heavy, charged, the silence almost painful.
“You think I didn’t see?” His voice was low, dangerous. He stepped closer, cassock brushing against your knees as you sat in the chair by his desk. “You let him touch you. In God’s house.”
You swallowed, trying to find words. “He’s my boyfriend, Father, I—”
“No.” His hand slammed down on the desk, the sound making you flinch. His eyes burned, blue fire under shadow. “He cannot give you what you need. Not your body, not your soul. That’s my duty.”
He crouched in front of you, hands braced on your knees, forcing your gaze to his. “Do you hear me? You break it off with him. Today.”
“Father…” your voice trembled, heat flooding your cheeks. “That’s not your decision.”
“It is,” he growled, fingers sliding higher up your thighs, thumbs pressing into the soft flesh until you gasped. “Because I’ve already claimed you, lamb. You confessed your sins to me, and I took them into myself. You’re mine now. Mine to guide. Mine to care for.”
His hand slipped under your skirt, brushing against the damp heat already soaking through your underwear. “Do you feel this? Tell me he does this to you. Tell me he makes you tremble in a church pew just by looking at you.”
You shook your head, breathless. “He doesn’t—”
Bucky’s smile was dark, triumphant. “That’s because he’s not meant for you. I am.”
And when he dragged you from the chair into his lap, robes parting, cock already hard against you, you knew the sermon wasn’t over.
He didn’t give you a warning—there never was one with him. One breath later he was kneeling again between your thighs, fingers parting you like a benediction, robe pushed up, rosary knocking softly against his wrist. The room smelled of old paper and candlewax, the hush of leaving parishioners still clinging to the walls, and his mouth was hot and urgent.
“Say my name,” he murmured, voice rough as a confession.
You obeyed—his name a prayer on your lips—because you’d spent too many nights whispering it into pillows, because the sound of him turned all your shame into worship. His tongue found the place where you ached, mapped it with slow, precise devotion. He tasted you like scripture, like something sacred he wasn’t supposed to touch, and everything inside you folded toward that heat.
His hands kept you open, soft and commanding, thumb tracing lazy circles over the place that made you dizzy. “Look at me,” he demanded, and when you did he swallowed you whole with his eyes: hungry, reverent, terrible.
You trembled, close, the world narrowing to the scrape of the desk, the bead of sweat at his temple, the impossible hush around his breathing. Just when your body was ready to give, when the first bright edge of release started to nudge you forward, he pulled back. The sudden absence was worse than the act itself—cold air on your wetness, silence where the hymn had been.
He rose with that terrible, sacred composure, eyes burning as if forged in some private hell. For a beat he simply watched you, like a man counting the measure of a soul. Then he leaned close, breath hot in your ear, and the words came out quiet but absolute.
“Leave him,” he said. “Leave him and marry me.”
The floor of your certainty dropped away. “What—” you managed, voice raw, half-laughing, half-pleading. “You’re a priest—”
“I am a priest who knows what you are to me,” he cut in, steady as a command. “It is my duty to care for you. To guide you. To wash you. Not only inside these walls.” His hand cupped your cheek, thumb stroking the tremor there. “Marry me. Let me be the one to hold your vows—so I can keep you clean in the dark, the same way I’ve been doing in the light.”
You could feel the weight of the rosary at his wrist, the tiny crucifix like an accusation. He sounded impossible and devastating and unbearably sincere, like a sinner who’d decided to sanctify the sin by ownership. The proposition was insane—but then, so was everything between you.
“Marry you,” you repeated, tasting the words before they’d settled. Your body still buzzed with the aftershocks he’d teased out of you, and that ache at the center of you flamed with want. “To be… yours? Publicly? Secretly?”
“However you need,” he said, voice folding around the mercy of the promise. “Secretly, if you must. Or loudly, if you want me to claim you in front of God and man. But break him off. Give me the right to cleanse you without looking over my shoulder. Let me be the one who says your name and means it.”
A laugh bubbled up—broken, incredulous. “You want me to leave him… for you? For this?” You gestured, helpless, at the ink-smudged appointment book on his desk, at the collar at his throat, at the chapel windows where light still pooled like witness.
“Yes.” He sounded both brittle and ferocious. “I want you to be mine in every sense. I want the right to mark you as saved by my hands. To be the man who takes your sins and keeps them where they belong—on me.” His fingers tightened in your hair, gentle and not, anchoring you to the moment. “Answer me.”
You should have run. You should have fled the office, called your boyfriend, untied the rosary from some dusty place in your head and burned it. Instead the heat that had been poured into you—his ministrations, his lips, the way he’d made you pray as you came—pressed you into a single, reckless decision.
“You would… if I asked?” Your voice was a tremble gone brave. “Would you really do that? Marry me?”
“Yes.” The syllable was a blade of light. “I will."
He was asking more than a name on a registry. He was asking for the fracture of your life, the burning of safe things, the letting go of a hand that had once kept you from being alone. It was monstrous and impossibly tender. It was a vow tangled with lust.
“Then… prove it,” you said, breath hitching. “Prove I’m worth the sin.”
His grin was a dark benediction. He pressed his mouth to yours—hard, holy, claiming—and this time he didn’t pause. He moved with the surety of a man who had decided on damnation. He laid you back, let the rosary slide from his wrist and coil on the desk, and then he kissed the place inside you where warmth pooled, where your answer lived.
He buried himself deep, hands braced at the small of your back, and you rode the rawness of his need until the room blurred. Each thrust was a sermon; each cry, a confession. You said his name like a vow, and when you came it was all at once: the relinquishment of what you’d known, and the terrifying, sweet acceptance of what he offered. He followed, heavy and hot and utterly his, and when he collapsed over you afterward his breath was a shaky psalm.
“I’ll make arrangements,” he whispered, thumb drawing lazy, possessive lines over your clavicle. “I’ll make it right—for us. For you. For what we are.”
You let the truth of it settle in the smear of candlelight and sweat. Outside, the church bells wound down into the evening; inside, the two of you lay tangled, secrets braided with something that would be called many things by other tongues—sin, salvation, love. You didn’t know what the church would say, what the world would do, but when he threaded his fingers through yours, rosary forgotten on the desk, you felt—terrifyingly—safe.
