God Izuku never cared much for the sacrifices his disciples offered him, but this one… this one is different.
#bkdksinweek #dkbk #dekubaku

His slender body kneels before the altar, head slumped and shoulders low. Chains encircle his wrists and there’s the faint smell of blood filling nostrils of Izuku’s disciples. To them, it’s nothing but a putrid reminder of the things they went through to secure the virgin boy.

To Izuku, it smells sweet of honey and fine wine. He watches from above with feigned interest— a virgin to maintain the crops, to ensure fertility, a gift a plentiful harvest come time. Izuku’s people have provided time and time again, and he readily accepts every gift received

at his altar. He loves his people despite their archaic rituals, and it satiates the creeping desire for carnage that stirs every so often within him.

Someone dressed in dark robes hoists the boy up onto the altar, back slamming against marble with a dull /crack/. Izuku perks

up in interest when his eyes flicker open— dark red like rubies, like merlot, like dried blood. The boy can’t be more than sixteen or seventeen, with defined muscles from years of farm work on his smaller frame. Izuku could easily take him in his palm, squeeze, and he’d crumble

to dust in his touch. Yet, despite his predicament, the boy’s conviction remains. He curses at the disciples and thrashes about on the altar, weakness overshadowed by determination.

He’s not sure how he’s overlooked this one for so many years. It’s not a mistake worth repeating.

By the time Izuku appears at the altar, the priest has placed a thin white sheet over the boy. Everyone at the ceremony drops to their knees, heads pressed against the dirty floors. Izuku has not come to visit his humans in the flesh in at least a century and the shock shows on

their faces.

“That will be all,” he says to the priest, the God’s bodily form towering over the otherwise large man. He can feel the uncertain aura of his people but no one makes the mistake to question him. They leave Izuku and the boy with a short word of prayer.

When alone, Izuku pulls the sheet off the boy. His face is smeared with the dirt from his struggle and somehow he is still the most beautiful creature Izuku has ever laid eyes on.

Those red eyes bare into his soul, questioning and angry. “I won’t hurt you. Tell me, what’s your name?”

Disbelief. It’s warranted, being chained at a sacrificial altar and all. He wants the boy to feel safe with him, to know he means no harm.

Izuku breaks the chains with ease, carefully taking them from sore wrists. He doesn’t dare move as Izuku does this. “Katsuki Bakugou,” he offers with hesitation.

“Katsuki.” Izuku plays with the name on his tongue, a shiver of delight running up his spine. “You’re beautiful, Katsuki.”

No answer. This elicits a soft chuckle from Izuku, overbearing in size as he hovers above Katsuki, posed like a lamb ready for the slaughter.

“If you’re going to kill me, fucking get it over with.” Brash, even before a God.

“As I said before, I don’t want to kill you. Do you want to die?” He asks.

Katsuki presses his lips together in a frown. “No, I don’t. What kind of question is that?”

“A valid one,” Izuku says with a smile. He cups his face with a hand much too large and strokes his cheek with his thumb. “Katsuki Bakugou. Let me have you.”

“W-what? Have me? The fuck is that supposed to mean?” Katsuki pretends not to understand the weight of Izuku’s

request.

“Give me your everything and I’ll return the favor. You live and live and live. No more sacrifices from you, or your people.” If it meant having him, he’d give up the world.

“Why me?” Katsuki asks sharply after some thought.

“Because, there’s no one else.” A God knows a soulmate, a past lover, a connection, just by the look in a human’s eyes. Izuku has and will kill for the man displayed at his altar. The air is electrified with the magnetic pull of their tether to one another.

Katsuki feels it too, he must, as he leans into Izuku’s touch with the carefulness of a glass doll. He nods without words.

“Say it. Say that you’re willing to be mine.”

“I want to be yours.”

Izuku devours him in a kiss. Katsuki is sloppy with inexperience and he reaches out to grasp at skin, desperate not to be all consumed by the God ready to obliterate him.

Katsuki grunts as he’s repositioned with his legs in the air and Izuku gets to /his knees/ for a taste of him. A God with bruises on his knees to please a human— he’d be the laughing stock of immortals if anyone were to find out. He finds that he does not care.

Izuku laps at his exposed hole, plunging deeper with every moan or noise escaping Katsuki’s lips. The human has his arm over his mouth and he’s biting into skin to keep his cries of pleasure to himself. It only makes Izuku work harder.

A finger enters Katsuki alongside the wetness of Izuku’s tongue and the sound alone could cause him to climax. Spit pools at Izuku’s lips and he allows it to gather at Katsuki’s ass, lubricating the entry of another finger. The stretching and waning of Katsuki sends him over the

edge, and he comes on Izuku’s fingers with a shaking orgasm.

Satisfied, Izuku brings his hand to his face and tastes the sweetness of Katsuki’s release. It’s marvelous, much better than blood or the richest of wines.

Katsuki is flushed pink, panting as he relaxes into the altar. Izuku isn’t done yet, no, he craves the feeling of “deflowering” the pretty human.

“Perfect, perfect, perfect,” Izuku mutters against his skin. He kisses the softest part of Katsuki’s inner thigh and prepares

himself.

Katsuki’s eyes go wide with the sight of his cock, the girth and length far surpassing the average human male’s. He closes his legs up in an attempt to slow Izuku down, who readily presses the tip against his ass. “No way is that going to fucking fit, get real!”

Izuku lets out a dark chuckle, using his palm to spread his legs back apart with ease. “It’ll hurt at first but I’ll make it good for you, I promise.”

Katsuki has no choice but to accept this as true. Izuku pushes in and he imagines what the pain of being split open must feel +

like. His ass is tight and warm and while Izuku’s cock doesn’t fit entirely, it’s enough to scratch the itch of filling up Katsuki.

He whimpers under Izuku as he slowly begins moving. It’s as gentle as the size allows it to be, still too much as his stomach bulges with every

thrust up into him.

It’s too much for Katsuki. He swears and scratches and whines, overstimulated by the cock pushing him wide open. To Izuku, it’s euphoric. No human could make Katsuki feel the way he does now. He’s ruined, ruined on his cock and will never want anything else.

Katsuki latches his arms around Izuku’s neck as best as he can, nails digging red circlets into flesh. He picks up his rhythm, thrusting against the prostrate until Katsuki’s coming again and convulsing as if he were possessed.

Izuku pushes through the other’s stimulation, coming inside of Katsuki, warm and full. He waits to remove himself as he admires the wrecked mess of a boy that trembles with orgasm under him.

His stomach puffs with his fullness and cum dribbles out of him as Izuku pulls out his

cock. He kisses Katsuki gently, once on the forehead, twice on the cheek, and the third time on the lips, now covered in drool. Red eyes are brimmed with tears that refuse to fall and Izuku wants to immortalize this sight.

When he recovers, Izuku fucks him again. Katsuki bobs his head on the tip of his dick, mouth stretched to its full capacity and unable to reach the base. They come and come and come.

Izuku wraps the sheet around his shoulders when the finish, presses kisses to blond locks with

adoration. “Will you come to me again, next year?”

A proposition— a new ritual. Katsuki nods.

Izuku lingers a moment longer before leaving him at the altar with a promise to see him again. Katsuki remains there to decompress, flustered and full and hazy eyed.

The next day, word gets out that their God will now refuse all sacrifices. He has made a new deal and as long as

it’s beneficial to both parties, it will remain the new ritual.

The weather that year is perfect. The crops survive and there’s a plentiful harvest that is followed by magnificent parties filled with food and drink. The women who wish to, bear beautiful children, and the

everything is full of love and reeks of wine.

When the time comes, Katsuki arrives at the altar. Izuku stands there, waiting with open arms.

—END.
