Toji sat in the dim light of the forbidden room, the one he had explicitly told his four-year-old son never to enter. The air smelled of oil and steel. His calloused hands moved with practiced precision, dragging a whetstone along the edge of his favorite cursed tool. It was a short, wicked blade with a cruel curve that seemed to hunger for flesh even when idle.
It was not that he did not trust Megumi not to hurt himself. The boy was careful, too serious for his age. No, the real reason Toji kept the door locked and the room off-limits was simpler. He had promised Megumi he was done with the Sorcerer Killer life. And he had lied.
The rhythmic scrape of stone on metal filled the small space until a familiar voice echoed from the genkan.
“Daddy, I’m home!”
Toji’s hand stilled. The blade gleamed under the single bare bulb, sharp enough to split a curse in two with barely any effort. He exhaled slowly through his nose, wiped the tool down with a cloth, and slipped it into its sheath before standing.
“Coming, kid,” he called back, voice low and rough, the way it always was when he tried to sound normal. He stepped out of the room, locking the door behind him with a soft click that felt heavier than it should. Megumi was already kicking off his shoes, a school bag slung over one small shoulder, his dark hair slightly messy from the walk home. Those sharp green eyes, too observant for a four-year-old, lifted to meet Toji’s.
“Thought you promised you were done killing,” Megumi said. His voice was so serious and flat for a child who had only walked the cruel world for four years. He eyed the sheathed blade that Toji had stupidly forgotten to leave in the room.
Toji tried to cover the mistake with another lie. “It never hurts to keep the tools sharp in case we need them for protection.”
His response seemed to satisfy Megumi for now. But to make sure his boy completely forgot about it, Toji dropped to his knees so he was at eye level with him. “You did good today in school. Didn’t get a single phone call about a fight like usual,” he said, giving his son a gentle and slightly awkward kiss on the cheek before adding, “Why don’t we have a little movie night? Just you and me.”
The way Megumi’s tiny green eyes widened and sparkled at the mention of actually getting to spend some father-son time with him stung Toji. He really was a shit father if his son got this excited over something as simple as a movie night. It was the same way most kids got excited about Christmas.
Toji watched as Megumi ran off to his room to change into something far more comfortable than his school clothes. While the boy was gone, Toji returned to the forbidden room and placed the blade back where it belonged, locking the door with a quiet click. When he came back and sat down on the couch, his heart stopped for a moment. Megumi had returned wearing one of Toji’s t-shirts. It hung on the boy’s small frame like an oversized nightgown, the hem reaching past his knees.
From the looks of it, Megumi had decided against pants entirely. A normal father would have told his son off for walking around without pants on. But Toji was anything but a normal dad. He simply patted his lap, offering Megumi to come as close as possible. His son deserved to be spoiled after all. Toji had been a shit father up until now.
It probably said a lot about Toji that he smiled at how fast his little Megumi rushed to climb into his lap, as if taking too long might mean the opportunity would fade away. He wrapped his strong arms around his boy’s waist to keep him in place as he reached over to press play on the movie Pocahontas.
The colorful film played on the screen, but Toji wasn’t paying attention to it at all. His whole focus remained on the way his son leaned into him so trustingly. One of his large hands stayed circled around Megumi’s small waist while the other rubbed what he hoped would come across as comforting circles on the boy’s bare thigh.
Megumi let out a small, contented sigh and snuggled closer, his back pressing closer against Toji’s chest. The oversized shirt had ridden up even higher on his legs exposing more of the boy's pale thighs, but the boy didn’t seem to notice or care. He simply had his green eyes fixed on the glowing screen.
“Daddy, look at the colors,” Megumi whispered during Colors Of The Wind, his voice soft with wonder. One small hand came up to rest on Toji’s forearm, fingers curling loosely around the thick muscle as if he needed to hold on to make sure his father stayed right there.
Toji swallowed. “Yeah, kid. Pretty, huh?” His thumb continued its slow, steady path along the soft skin of Megumi’s thigh. The motion was gentle, almost absent-minded, but Toji knew exactly what he was doing. He told himself it was just affection. Just making up for all the nights he wasn’t home. Just spoiling the boy who rarely asked him for anything.
A better father would have shifted Megumi to sit beside him. A better father would have fetched a blanket and covered those bare legs. Toji did neither. Instead, he tightened his arm around the small waist and allowed his hands to wander further up his son's thigh. Moving his hand a fraction closer to the pale pink cotton panties he knew his son liked to wear to bed.
Letting the boy’s weight settle fully against him as his hand slipped where no father had the right touch their child. He was the worst dad in history he's sure of it but the way he looks at it he's just rewarding his baby boy for being so good. Good boys deserved to be treated well by their daddy and Megumi was the goodest boy of all.
When Toji slips the first finger into Megumi’s tiny cunt, the boy lets out a small, surprised sound. Toji’s lips curl into a smirk. It’s one of the cutest noises he’s ever heard from him, and greed coils hot in his chest. The greed burns brighter than the guilt that gnaws at him deep down. He wants more. He wants every sound Megumi has to give.
"Such a good boy for Daddy. Such a good boy for letting Daddy touch you like this."
He whispers the praises softly in Megumi's ear as he fingers the boy a bit roughly, no one can really blame him for being slightly mean about it, he's never been a patient natured man. His precious little Megumi doesn't seem to mind though as he seems more focused on the praises than the rough treatment to his cunt.
The praise distracts him so thoroughly that when Toji pushes a second finger in beside the first, it punches a soft, broken whimper out of Megumi’s throat. Slick gushes around his knuckles, hot and sudden.
His baby boy just came from two fingers. Fuck if that wasn't hot. Toji’s cock twitches hard against the confines of his pants. He wonders, for a dizzying second, if Megumi would come just from the blunt head of his cock pushing inside.
He needs to prepare his boy properly first. No shortcuts. Not with something this tight, this precious. Shifting their positions on the battered couch, Toji manhandles Megumi until the boy can no longer see the movie. A few mumbled complaints rise immediately, but Toji soothes them away with a low chuckle.
“Shh, it’s okay, baby,” he rasps, voice dropping into a low, filthy purr thick with hunger and dark promise. “Daddy’s going to make it up to you later. Right now… be a good boy for me.”
Grinding against Megumi was like dying and ascending all at once. It was obscene to Toji just seeing how much of a size difference there was between them and he wasn't even inside him yet. Ruining Megumi was going to be like a repeat of the original sin. Every small needy whimper Toji pulls from his son he swears an angel gains its wings. It’s heaven and it’s hell.
The pits of hell are surely going to greet him when he dies for the acts he’s committing upon his own offspring but if sinning was this heavenly was it really such a sin? Toji doesn’t believe so as his large hands pull aside the pale pink cotton to reveal just how wet his precious blessing’s tiny virgin cunt has gotten.
Seeing how slicked up Megumi had gotten from a simple bit of grinding and rough fingering from earlier he can feel his cock twitch and leak precum in sweatpants he’s got to get his dick in there soon before he busts in his pants like an amateur teenager. He pauses his touches long enough to sling his pants low enough to free his large cock and he delights in the high, needy sounds his son makes when he isn’t touching him.
He might have failed to be a father to his son in other aspects of being a parent but he’s definitely chalk this up as a win for himself on making sure his precious Megumi always craves his undivided attention.
“Shh Daddy’s not going anywhere,” Toji speaks as softly as he can manage while brushing a thumb under his son’s eye where tears threaten to fall. With his baby soothed and reassured he starts grinding his now bare cock between the soaked folds of Megumi’s cunt.
A deep groan leaves his leaves scarred lips he’s not even inside yet and he already feels on cloud nine. Megumi’s so wet that he slides back and forth between the folds with perfect ease. Toji has fucked his fair share of whores but nothing or anyone comes as close to being as heavenly as his blessing of a son Megumi.
The tiny mewls he pulls out of his boy is the best music he’s ever heard, and it gets even better when those sounds hitch in the middle when the head of his cock catches on the entrance to his sweet blessing’s cunt. If grinding on Megumi was heaven that Toji has entered a whole new plain of existence feeling his son’s virgin hole suckle on the head of his cock as he attempts to push it in with all the patience he can muster.
Megumi’s cunt doesn’t resist him for too long. After only a few minutes of him thrusting in and out he’s already got half of his massive cock inside and he’s seeing stars with how tight it feels. It’s more perfect than he ever thought it would be. He can faintly hear Megumi complaining small whimpers of “It’s too much” and “Daddy it hurts” which he soothes with kisses.
“You’re doing so good for Daddy, Megumi just a little more. You can hang in there a bit longer for me can’t you?” He whispers into Megumi’s ear as he goes to kiss the smaller boy’s sensitive neck to distract from the pain of him shoving the rest of his cock balls deep. Once all the way in he can feel that he definitely penetrated his son’s cervix and see the outline of his cock through Megumi’s.
The sight of that alone makes him forget all about being gentle as he’s mesmerized by watching the outline of the bulge move in and out with his rough movements. He ignores the babbles of incoherency coming from his son’s mouth purely concentrated on the beautiful tears of pleasure falling from Megumi’s pretty green eyes.
He doesn’t even realize he’s close until he feels Megumi’s cunt squeeze him so tightly and spasm around him soaking his cock with fluids as it milks him for all he’s got. Toji doesn’t last long after that his son is perfect in every way and he must reward him for being such a good boy. He lasts about three more thrusts before he plunges himself as deep as he can, spilling inside while whispering praises and running his fingers soothingly through Megumi’s hair.
