    Summary

    "I mean," Tanjirou's gaze refocuses back on to him, but more specifically between his legs. "I want to eat you out."

    Zenitsu frowned, thick eyebrows drawing together in confusion. Why was Tanjirou being so weird? And why had he gone so red all of a sudden? And why was he looking at his-

    It finally clicked in his head. At once, the omega shot a beautiful scarlet, the blush reached to the top of his ears putting Tanjirou's own to shame.

    They've never had oral sex before.

    ———————

    Or, in which, Tanjirou gets exactly what he wants for his birthday.

    Summary

    After years of chasing (and getting chased by) demons, watching his fellow demon slayers dropping like flies and collecting an inordinate amount of near-death experiences, the last thing Zenitsu wanted was to be the victim of yet another plot twist, but there he was, presenting as an omega at the ripe old age of nineteen.

    Fate works in mysterious ways, and perhaps one more change of plans was exactly what Zenitsu needed to finally come face to face with what had been laid out in front of him all along.

    Summary

    “Oyakata asked me to put you on break for a few weeks.” Shinobu explained, sipping her tea quietly. “He says you should rest before your next mission, take your time and stay with Tanjirou while he heals.”

    He bit back a sigh. He would love nothing more than to spend a week or two with his new family, but the world didn’t work that way. People out there needed saving. He couldn’t just sit around and do nothing. He opened his mouth to say as such, but Kochou cut him off again.

    “You’re not the only demon slayer out there, y’know. You can trust other people.” She says, as if reading his mind. She stands abruptly, walking towards the window. “In a month, you’ll be leaving with Rengoku to scout out the Infinity Train. Take this time to rest and to prepare, I can tell it’ll be a tough mission.” She hummed, exiting the room without another word.

    It wasn’t long before Tanjirou and his bizarre friends came back from their training. Instead of going into his own bed, Tanjirou hopped up on Giyuu’s, slumping defeatedly against his caretaker’s chest. Wrapping his arms around his pup, Giyuu scented him. They’d go see Nezuko soon, but for now, all Tanjirou wanted was to be hugged. And who was Giyuu to deny him?

    Summary

    “Do you want to heat share?” Tanjiro gaped for a couple of seconds which caused Zenitsu to wave his hands in front of him in panic.

    “I-I mean I’ll return the favor of course! Whenever you’re in a rut I can help you out. You know like-you scratch my back and I’ll scratch yours?” It takes another few seconds for Zenitsu’s words to register, and by then the omega was muttering something suspiciously that sounded like, “maybe I should of tried with Genya instead,” which only propelled Tanjiro to shout a loud, “YES! I WOULD LIKE TO BE YOUR HEAT PARTNER!!”

    Summary

    A snippet of life in the Kamado household:

    Eight months pregnant, Zenitsu pestered his alpha to attend a festival in a nearby town. Tanjirou met with an acquaintance who wanted to thank him for helping her village.

    *

    "Oh, oh! Shi-chan, have you seen that guy in black haori over there?" He heard a girl beside him talking to her friend. "He just looks so handsome!" She said giggling.

    "I kinda want to talk to him, maybe invite him to see the fireworks later?" 'Shi-chan' sighed dreamily and Zenitsu almost choked on his takoyaki.

    "Too bad. The girl he's talking to might already be his girlfriend."

    "Auntie, can I have more yakitori?" Zenitsu calmly said, glaring at his husband. He would have devoured all the food in this stall and she might still be not finished thanking him.

    Summary

    "I gave my life to you. Even knowing you could never love me the way I love you. Still, I’d do it again. In some other life, if the stars are kinder, I hope you’ll feel what I feel. Just once. That would be enough.” — Uzui (Agatsuma) Zenitsu

    When Emperor Tengen issued the decree—a command for all unmarried omegas to present themselves for royal selection—Zenitsu obeyed, as all good citizens must.

    He did not expect to fall in love with the Emperor first.

    Zenitsu did not think through this whole Red Light District mission. Apparently omegas sync up their heats. He knew this, sure. He did not prepare for it. And then, Tanjiro comes knocking on his window. Geez! Can't the guy see Zenitsu's having a crisis here! Wait, don't come in!

    Summary

    "So tell me," Zenitsu began internally cringing at the display of pure corny-flavored sweetness that he had been forced to witness by agreeing to eat with his kind, warm-hearted friend.

    Tanjirou meets his eyes after plopping another portion of rice in his mouth. He cocks his head, and indication for Zenitsu to continue. Such pure innocent curiosity found in pink-round orbs. Zenitsu's gong to obliterate it.

    "So tell me Mr. Kamado how does it feel to be a cradle robber at age 16?"

    Tanjirou promptly chokes.

    Author's note: I added a bit more for chapter three because I thought it was just too short and that did not sit well with me. Chapter four is under construction!

    Summary

    He feels it before he can react – a weight blanketing his consciousness, forcing him into submission as his mind whites out. Zenitsu has no choice but to submit, his knees hitting the ground as tilts his head back to expose the long column of his neck and his belly. His eyes remain unfocused, but he knows he's staring up at the sky – clouds rolling past overhead as his ears pick up the distant sounds of Tanjiro and Inosuke's voices.

    "–astard! Bastard! Let him go now, right now!"

    Inosuke is shouting, but Zenitsu's head feels heavy like he'd just woken up from being asleep.

    "Release him! Shinazugawa please!"

    Now Tanjiro's shouting too. The voices of his best friends sound like they're far away, distorted as if his head were submerged underwater.

    "You can't use commands on him," he hears Tanjiro plead, voice watery. "Not after what he's been through."

    ---

    Shinazugawa Sanemi is bad at being an alpha, and Agatsuma Zenitsu tries his best.
