power, choking, devotion

cw dubcon, face-fucking, public, mind break

His monastery had been burned to the ground months ago when the barbarians across the water had raided it in search of gold and silver.

Izuku, unwilling to flee along with his brothers in Christ, had stayed behind to try and salvage what he could of God's House.

The only home he'd ever known since he was taken in after the head priest had taught him there was more to life than thievery.

He couldn't leave it behind, even if it meant going down in flames with it.

That, however, was not what he was destined for.

"You don't seem anything at all like those old cowards." The leader, a hulking blond of a man with inked skin and braids along the side of his skull, spoke.

"You fight with your fists, not words. Unbecoming of a holy man, no?"

Izuku, beaten down with a bloody lip and a swollen eye, glares at his captors. For that's what he is now. A spoil of war.

"There are times when God calls for action."

"Only fools follow blindly, little priest." Izuku's chin is lifted by the tip of a blade, red eyes boring into defiant green. "I could make use of devotion like yours."

Izuku is taken. Taken further than he's ever been.

The sway of the sea beneath his unsteady feet has him sick for days, his stomach heaving out bile when nothing else is left.

"Is your God with you now?" The blond leader, Katsuki, mocks, leaning against the railing of their great ship.

"Always."

The Viking only hums with amusement. Doubtful, red eyes glinting with the slow smirk that stretches across his handsome face.

"Hm. We'll see."

Izuku prays to his Father in heaven weeks later, in Katsuki's home, surrounded by furs and a large hearth. Sweating and crying out as Katsuki deigns to take it upon himself to teach him the pleasures of the flesh.

Something he only remembers as a necessity to get by rather than something to be enjoyed.

He's tied to the bedpost as Katsuki reaches beneath his robes, large body between his legs to keep them from closing.

"Father God, who watches over me-!" Izuku babbles, hips bucking up into Katsuki's wet fist around his cock. "F-forgive me my transgressions-!"

The blond is laughing, relishing in the unraveling of his priest, the power he holds over the other man.

"I don't think he's answering, /Father./" Katsuki fucks a finger into that virgin hole, drinking in the gasps it elicits. "What use does he have..."

Katsuki pumps and pumps, grinning as the priest begins to arch, little cock leaking profusely with his incoming orgasm.

"....for a holy man that cums from his ass?"

And Izuku is. He's cumming and cumming, clenching down on the thick digits against his prostate. Face wet with tears and snot and spit, he prays for forgiveness.

Forgiveness for just how much he never wanted this feeling to end. For how, very soon, he'll be begging for more.

A year later, and Izuku's prayers are all but dried up. His focus now solely on worshipping /Katsuki/.

The collar around his neck, a mockery of his once pristine cleric garb, tightens against his throat.

"Hungry, little priest?" Katsuki tugs at the leather leash, bringing Izuku's flushed, dazed face closer to his crotch.

They're in the dining hall, Izuku beneath the table, on his knees where Katsuki has kept Izuku mouthing at his clothed, half hard cock.

Izuku doesn't answer, the chatter and laughter around the wide room too loud to carry words properly.

Instead, Katsuki smirks at the look Izuku sends him. Undoing the knots of his belt, he pulls himself out.

"Go on then."

Like the desperate man he's become, Izuku sucks that thick, wet head into his mouth and moans softly.

Murmurs his prayers along the smooth shaft, praising his new God. Holds the weight on his tongue, pushes it against each cheek to carve the taste into his mouth.

He sucks and chokes when the collar pulls in response.

A snarl and the scrape of Katsuki's chair against the wooden floorboard, and Izuku is pulled completely onto Katsuki's cock. Ring clad fingers wrap around his loose curls.

"You've gotten so good at this, Father." Katsuki grins down, grinding his cock further into Izuku's throat.

"Can't help myself."

He fucks Izuku's mouth hard and fast, pulling Izuku's head to meet his pelvis with every flex of his arm. The Hall is deafening around them, Izuku's moans for Katsuki's ears only.

"F-fuck-!" Katsuki laughs, breathy and guttural. "He may not hear you anymore, but I thank your God and mine everyday for allowing us to meet."

He continues to fuck into Izuku's face, who's green eyes have long since rolled back.

Drool splatters to the floor, the wet slaps fueling Katsuki into hunching over the ex-priest. He pistons Izuku's head faster, grunting as orgasm approaches.

He grins at the catcalls and tightens his hold possessively.

"See that?" He calls into the crowd. "My perfect little slave."

There's laughter and cheers, distractions that Izuku pays no mind to, his focus solely on the way he can feel Katsuki's balls tighten against his chin.

His bound hands (unnecessary now, but Katsuki likes it) press over his own cock. His garbled moans are interrupted as Katsuki smashes his nose into blond pubic hair with a snarl.

Any sound Izuku could make is forced back down with the thick, hot cum shooting down his abused throat. The collar and spasm of his instinctual swallow, milks Katsuki's cock further.

Katsuki curses above him, stroking green curls almost reverently.

"Thanks for /prayer/ Izuku. Time to eat."
