De•mon
an evil spirit or devil, especially one thought to possess a person or act as a tormentor in hell.
"he was possessed to fuck an evil demon"
Tanjiro, for a demon, despised little in the world— however, there is one single thing in this life that he held immense disdain for, well, perhaps not immense, but a fair amount of.
And that was the discomfort that threatened to crawl from the shivering cocoon in his spine to his strained smile that seemed to come to his face automatically when his eyes met that familiar and ~~divinely, atrociously, and heinously attractive~~ gaze of pastel rainbow.
Lord Douma for one was acutely aware of the priest’s lack of fondness whenever he entered the room, he couldn’t help it, it *was* his church. Sure he knew that some days his presence was not needed ~~nor wanted by Kamado’s opinion~~ , but he often found reason to come anyway. Whether that be to “check” on his demonic priest, or to preach to the ~~annoyingly needy~~ choir of human beings.
“ Lord Douma, your presence is unprecedented..” Tanjiro was calm, but his tone did hint at the presence of a sense of discomfort and slight annoyance, he tried to mask it though. But, Douma was far too well-versed in everything Tanjiro Kamado, the demon was quite easy to read—in fact he was like an open book with transparent flaps from cover to cover.
“ Yes yes, it is isn’t it? Are you saying that you forgot I was coming today?”
Oh… yes indeed. It was time for their “monthly check in”.
The red haired demon would let out a sigh, his breath heated from the fire he usually breathed, slowly beginning to unravel the priestess outfit Douma made him wear. At the very least Douma let him be clothed now, when he first came up from Hell and began to work as the “Saint”’s ~~demonic~~ priest he was only allowed to wear undergarments(if that).
“ Is..is this really necessary?” He asked, hand settled on the black fabric that hid his hair, God forsaketh me, the demon hated how this familiar scenario continued to turn him on, whether it was this night or the next, whether he was angry or sad, he always found himself submitting and ~~begrudgingly~~ happily to the Saint, on his knees as if in some sick form of prayer, ready to suck the holy liquid directly from the girthing source. Or whatever else douma had in plan for that night.
He honestly had no idea why he asked.
“ You want to pay off your debt no?” Douma’s grin was heard through his words—which Tanjiro found very annoying. He did not like how he knew the Saint so damn well that he was able to sense a quip before he even made it.
Tanjiro’s Demonic Debt was the one reason he was here in the first place.
It was a mere two thousand years ago, he was simply trying to look after his sister, she had wondered from Hell and right onto earth. He hadn’t meant to cross into Angelic territory—which to be fair they all seem to encompass th earth anyway— and found himself fighting off lesser angels while trying to protect Nezuko. In the process he broke the Holy Chalice.
He could remember the sound the divine object made when it came in contact with the ground, teething with angelic energy, shattering to seven pieces which split into seven more..and more.
He could remember Douma’s ~~infuriatingly smug~~ expression that decreed his debt be paid long as he stuck by the Saint’s side and did ‘favors’.
Unfortunately sex was a pretty big favor.
Also more unfortunately Tanjiro was an incubus.
“Tanjirooo ~ come here,” Douma’s tone echoed how the Saint felt, he truly never did “feel” outside of these sexual encounters with his Priest. Well, that and eating his followers who commit sins.
Tanjiro took small steps toward the Saint, he could swear in these heated moments the man glowed with a divine light that eclipsed the sun itself. Or perhaps that was the demonic pheromones that made him nothing less than a bitch in heat. Or both.
Sitting down where he knew he should, on Douma’s lap. Tanjiro’s face reddened, feeling that prominent bulge underneath his buttocks. He could swear to Satan that that thing continued to get bigger each day.
Douma hummed, putting his head on the demon’s shoulder, running a sharp bit gentle finger across Tanjiro’s bellybutton. “You know, Priest, I don’t think we’ll do penetration today, okay?”
Tanjiro would’ve let out a sigh of relief **if** the Saint would’ve let him finish the thought.
“Ack!”
Tanjiro’s holy garments were torn off his body, letting the cold chill of the church house hit his lithe frame. Douma had cut a little too deep and actually knicked the poor demon.
“Douma—“
“That’s not my name..” Douma corrected with an easygoing smile still plastered on his face, he knew he had cut the boy, he did that on purpose probably.
“ Lord Douma, you nicked me!”
“Did I? Apologies!” He wasn’t sorry at all.
Tanjiro barely caught his breath from the incision just before Douma had lowered his head to his neck. The small hum of an unheard ‘May I?’ Being the wordless warning before Douma sunk his teeth into the Demon’s neck. Douma could attest that he tasted far better than any human he’d consumed before. Douma enjoyed the taste of the demon, he’d eat him all up of he could. Well, he does that anyway.
Tanjiro let out another stifled scream~~more like moan~~ as the Angel’s teeth sunk into his flesh, crimson dripping from the still occupied wound. His skin was prickled, an angel’s teeth were like water to fire, they didn’t mix, but that damn sure didn’t mean they didn’t make a steamy combination.
“Dou—“
A firm hand tapped his side, poking him with a sharp nail.
“Lord Douma..!” The demon was already asphyxiated, Douma had a nasty habit of biting too deep and too harshly. Tanjiro still had scars from their very first encounter over 2000 years ago!
But that thought was a fleeting one as the demon gasped again, feeling Douma’s large, cold hand wrap around his clothed crotch like a snake. His cock was already painfully hard, emphasis on the pain. Douma relished in it, sinking his sharp fangs deeper into the demon, making sure to elongate his teeth so he’d reach deeper, hell, maybe even puncture a lung or two.
“Mm….i know, I know,” The Saint assured, face still smothered in the Demon’s neck, his words vibrating through the demon’s body. How he was so tender sounding yet so terrible all at once was definitely one of God’s “mysterious ways”.
Tanjiro’s cries went unheard as Douma continued to deepen his bite and suck more blood from the priest. Tanjiro, despite his better judgment, couldn’t stop the arousal from peaking and it only got worse when Douma began to do slow, calm, almost playfully faint strokes on his member. His sharp finger nail dancing over the head of his cock before resuming those repetitive and heinously slow motion.
‘In and out’ is what Douma mumbled to the boy, running one hand up and down Tanjiro’s forked cock while the other fiddled with his small bellybutton.
Douma’s cock pressed against his white garments, for an Angel he enjoyed all sorts of decadence and lecherous activities—one was fucking the absolute hell(pun intended) out of his priest. He loved how ‘Lord’ sipped from his lips, how much he could twist and mangle this Angel of a demon
Well clearly.
