Summary
Kimetsu Academy's final term end exam season has finally ended. Shinobu's batch has graduated.
For high school biology teacher Kanae Kochou and high school maths teacher Sanemi Shinazugawa, it has been three relentless months of grading papers, invigilation shifts, and sibling tutoring sessions that left precisely no room for anything else despite being live-in partners.
On a quiet Sunday morning in March, Kanae finally has the apartment to herself.
She has plans to relax in the best possible way.
Sanemi has impeccable timing. -

Summary
Post Infinity castle war. After the fall of Muzan, the Demon Slayer Corps are abandoned and the Marks have vanished. The survivors of the Corps begin rebuilding their lives.
For 5 years, the Wind and the Flower danced around each other but were too afraid of rejection and the shadow of death to confess what they truly felt for each other. Now, with the promise of new future, sky's the limit.
As they navigate trauma, survivor’s guilt, and the slow healing of old wounds, Sanemi and Kanae finally allow themselves to want each other. With a little help from their respective siblings.
All leads to their sacred union and a passionate night of lovemaking and marital bliss. (Chps 4 and 5 btw if you want to jump straightaway into it 🤭😏🫣)
(Memories are in italics. It's my first work, so constructive feedback is welcome.)
Referred to Sanemi and Kanae as the Wind and Flower in their third-person chapters for a poetic flair.

Summary
Fem! Sanemi and Fem! Kanae.
Basically just a fic of Sanekana yuri because why not. Also GenMui yaoi cuz I love them!
Kanae is still a girl, but now Sanemi is too! (You can imply that Sanemi in the fanfic is either trans or cis)
Also the title lowkey sucks.

Summary
Four weeks after becoming a father, Sanemi Shinazugawa has learned a few important things: babies are tiny, terrifying, and somehow capable of making your heart explode from love. Unfortunately, they're also capable of destroying sleep schedules, relationships, and any remaining sense of sanity.
While Sanemi tries to survive life with a newborn, the people around him are dealing with their own little disasters - and Giyu Tomioka is blissfully unaware that one very big surprise is quietly waiting for him.
Sequel to Silent nights, gentle ties.

Summary
Gently, Sanemi reached over, gently brushing a damp strand of hair from her face. "A pretty girl should cum every night," he murmured, smirking down at her before pressing a soft, surprisingly tender kiss to her temple. He stayed there, patient, waiting for her breathing to even out. "B-but...hah...I c-can't," she panted out, frustration lacing her shaky voice. "Yes, you can. Stop overthinkin' and you'll get there." His voice was surprisingly sweet; a stark contrast to the cruelty from moments ago.
Before Kanae could fully catch her breath, Sanemi moved back down between her thighs. He knelt, his hands catching her shaky ankles in a firm grip, and shuffled forward. “Cumming is all in the mind. You’re beautiful and more than enough. Fuckin’ relax and let go.” Sanemi continued his motivational speech, bringing tears to Kanae’s eyes.
Or Kanae wants to get dicked down so badly to the point she has reoccuring wet dreams about her boyfriend as an Incubus. Kanae fights other demons *Please read I promise it’s worthwhile and mega horny!* Comments and kudos are appreciated. Read my other works too <3 >_<
