Summary
“…she’s adorable,” the baby coos in Giyuu’s rocking arm. Tiny, chubby hands reaching out for his hair.
“she is! isn’t she?” Mitsuri grins proudly, staring at her daughter in Giyuu’s hold, babbling at the blue-eyed omega’s attention.
Mitsuri smiles softly, “you know… you’d make a pretty mother.” The rocking stops and Giyuu froze almost immediately.
The blue-eyed omega went home that night imaging a little girl with white hair and blue eyes, running around their shared home.

Or after interacting with shinomitsu and uzui’s kids, Giyuu catches a baby fever bad. Good thing Sanemi’s a responsible alpha!

Summary
“What hair color do you think our pup would have?” Katsuki almost drops his cup from Shouto’s sudden question— the tea spilling a few drops on the table. The alpha hesitantly puts it back on the table before he faces the omega beside him.
“What?”
Shouto sets down his cup as well and meets Katsuki’s gaze, “I mean there’s so many possibilities on what hair color they would have, it could be white, red, blonde, or even a shade of dark blonde like your father’s?” He says too casually for Katsuki’s understanding.
“Icy— Shouto.” He grabs the omega by his chin, not enough to hurt him but just to get his attention. “We’re— we’re not even together?”
—
Or 5 times Shouto thought (out loud) of a baby with Katsuki + the 1 time Katsuki made a baby with Shouto.

Summary
Katsuki lets his omega pull him with a fond smile. His omega excitedly grabs the small present he had wrapped for Katsuki and shyly presented it to the alpha. Pink tinged Shouto’s cheeks as he hands the gift to Katsuki, “I hope you like it.”
The alpha huffs and takes it, of course he’ll like it, it’s from Shouto. He unwraps the ribbons with precision, Shouto’s gaze practically burning at his face, waiting for a reaction and—
Oh. This is….
Or: It’s Christmas and Shouto gives Katsuki his present.

Summary
Shouto blinks, his vision a mix of green and blonde blur. He hears a series of different footsteps, followed by a panicked, “kacchan—“ and then—
A scream. His scream? Shouto doesn’t understand. All he knows is that he was tackled into the floor and then all he knew was pain, a searing hot pain passes by his neck— quickly followed by a rush of relief shivering through his body, a gush of wetness trickling down his thighs and— Oh.
He was presenting.
And Bakugou bit him.
Bakugou bit him right at his scent gland.
—
Or Shouto presents, goes into heat, then gets marked.

Tomioka Muichirou is the only son of his dad, Giyuu. Shinazugawa Yuichirou is the only son of his father, Sanemi—or so they thought.
Tomioka Muichirou and Shinazugawa Yuichirou meet for the first time at age 11 in the Hashina Camp, and everything they thought they knew begins to fall apart.

Summary
“I’m not sick,” Giyuu admits.
Sanemi scoffs and rolls his eyes, clearly not pleased with this. “Well, that’s bullshit because–”
“Sanemi, I’m not sick,” Giyuu cuts Sanemi off. “I’m pregnant.”
Sanemi goes silent at that.
or, an accidental pregnancy turns Giyuu's world upside down, all while the fight against Muzan and the demons rages on.

Summary
Marching over to the locker is a struggle with his sore thighs and calves, but he reaches to push the wooden door closed, when something navy blue dangles from the gap between the door catches his eye.
Izuku naively assumes nothing of it and goes to grab the dangling item, thinking he’ll simply pull it out of its wedged position between the locker rim and the door.
What Izuku doesn’t realise until the item is fully in his palm, is that he is holding panties. A pair of plain navy blue, cotton, full-coverage panties that were slightly damp from sweat-
Oh All Might strike him down.
Izuku was holding Shouto’s used panties.
———
Or, Izuku discovers a new kink he didn’t know he had.

Summary
“So, you want to know how to court an alpha?” Keigo leans over the table, sporting a mischievous grin. “You’ve come to the right guy.”
Toya stood up to gather the dishes, moving to the kitchen to start cleaning them. “Don’t teach him anything stupid, you bird-for-brains.”
“Don’t listen to him,” Keigo tells Shoto. “I’m an alpha; I’m the best person for this job. Now, listen up, Firefly, all of these are gonna be in the test…”
Shoto realises the new development in his and Bakugo's relationship. With Class 2-A's help, he realises that he's being courted.
After all of the effort that Bakugo had put into courting him, Shoto decides to reciprocate the affection. He hopes that if he reciprocates the courting, Bakugo will realise that he wants to be his mate, and that he wants the alpha to put a collar around his neck. The problem is, Shoto doesn't know how to court an alpha.
Who else would he go to for help other than the number two pro hero, who is an alpha himself, and just so happened to be his brother-in-law?
