Don't Call Me Baby (Unless You Mean It) by anjumstar

Summary
No one ever told Katsuki that bottoming fucking sucks. Not that he’d ever asked anyone (fuck you, why would he?). But if he were to find something else that he really likes, maybe it wouldn't be too bad. Maybe. Fortunately, his boyfriend is a nerd.

Summary
“Sorry,” Izuku gasps, finally able to draw a deep breath again. He fully expects Kacchan to leave, spooked by Izuku’s weird depravity. Not that Izuku ever meant to rattle him like this. He can’t help it; can’t help that he wants to intimately know every little part of him, like it was a part of himself.
But just as Izuku catches his breath, Katsuki grabs his hair to forcefully pull his head back.
“Guess it’s your birthday, so consider yourself lucky.”
He remembers, Izuku thinks and his heart skips a painful beat.
“You wanna taste it?" There’s something lurking in Katsuki’s tone. When Izuku nods with heated cheeks, Katsuki shoves his fingers into Izuku’s mouth. "Then here’s your fucking present.”
Izuku gags at the rough intrusion and Katsuki laughs, all teeth.
"Happy birthday, nerd. Now suck."

Summary
A deep flush tints the apples of Katsuki’s cheeks, pink cutting a warm line through his features in the darkness. “Because your self-esteem is shit. You beat yourself up for every goddamn thing, and part of it’s my fault, but calling yourself plain—”
“Uraraka said that.”
“—and acting like you’re some random extra and not the hero who saved Japan—well, you can’t blame that on me. So, here it is, Deku. You’re hot as fuck, and you deserve a lot more than the shit you got. Get your dick hard, because I wanna suck it.”
Izuku’s jaw drops.

Summary
Betas are criminally understudied. Always have been, hopefully not always will be, not if Midoriya Izuku has anything to say about it—which he does. A whole lot. It’s just a little hard feeling like no one really cares, and it’s even harder living in the very same sort of body, being the sort of body, that no one really cares about.
And then there’s the sex stuff. That’s the hardest part of all.

Summary
It’s late, and Izuku is already fighting a yawn by the time he steps through the doorway. But he’s feeling so good, and clean, and maybe a little soft around the edges, and he’s sure he must still be glowing as he emerges from the bathroom and Kacchan catches sight of him.
He can feel the moment he does.
A quirk links Katsuki and Izuku’s nervous systems.

How to Get Your Boyfriend’s Attention Sexually (WikiHow Steps) by shaggyherbals
Fandoms: 僕のヒーローアカデミア | Boku no Hero Academia | My Hero Academia (Anime & Manga)
27 Aug 2024

Summary
Katsuki has eyes, and a penis – he knows that Izuku is a walking wet dream. He’s still not entirely sure how he landed the sexiest boyfriend in the world, either, but it’s a very recent development. After having spent years pining over Izuku, Katsuki couldn’t help but pathetically spill his guts after giving Izuku the iron suit, about two months ago now. But, to Katsuki, they’ve been together their whole lives.
The only problem is: they haven’t had sex yet.
***
Or, Katsuki finds a way to get Izuku to sleep with him. He just goes about it the wrong way.

“Kacchan.”
“Ngh,” Kacchan says.
“You can take as long as you want to wake up,” Izuku mumbles into the ticklish skin of his lower belly. It hollows out from the brush of Izuku’s eyelashes, then his torso lapses back into the even rise and fall of drowsy breaths. “Whatever you want.”

Katsuki is the number three Pro Hero who deals with citywide emergencies on the regular, but it’s this self-sacrificial reckless little asshole that constantly has him flirting with another heart attack. Cardiac rehab kicked his ass for two years, and it still never covered how to deal with Deku.
“Dynamight-san,” Izuku says slowly, "I uh, didn't call anyone in."
"Yeah. I noticed."

Summary
"Does this..." Izuku says slowly, voice soft but sharp, "have something to do with your dream the other day?"
"What the fuck? No—" Katsuki starts, horrified.
"Thought it was a nightmare," Izuku says, voice low and syrup-thick, sly and cruel in a way that makes Katsuki’s stomach flip. "Turns out it was just a pathetic little wet dream, huh?"
He’s losing.
He’s already lost.
And Izuku—sweet, dangerous Izuku—is eating it up, all sharp smiles and dark, delighted eyes, like he’s thrilled to see him unravel.
