I can't get this image out of my head and I need to share it.
CW: size difference, manhandling

"Oh sweet! Babe, come look!" Kirishima calls from the bedroom. It was their day off, and Bakugou insisted that it was time to deep clean the apartment. He had set his boyfriend to work on their bedroom, and instructed him to clean out their closet first, while he could make his kitchen sparkle in peace. He rolled his eyes. He knew his idiot wouldn't get back to work until he came to see whatever the fuck was so important. Whatever. He needed a break from the smell of lemons and bleach.
"What is it?" He goes wide eyed upon seeing his boyfriend squeezed into his old UA uniform shirt. He looks like a werewolf mid-transformation, straining to keep his massive body from ripping the old shirt to shreds. Bakugou can see his abs through the gaping holes between the bottom three buttons that are doing their absolute best to keep the shirt closed, making his pecks bulge out of the window that Bakugou is so happy his boyfriend couldn't close. All of a sudden, the redhead can't hold his breath any longer, and the beautiful sound of buttons popping and seams ripping fills the room for a few amazing seconds as his muscles expand. He looks down at himself before smiling bashfully.
"Heh, I uh...found our old uniforms. Guess I grew out of mine." The understatement of the fucking century.

Bakugou doesn't say anything. He just stares at him with a blush on his face for a moment before stalking closer and planting his face in the middle of his boyfriend's perfect fucking pecks.
"Fuck you."
"...why?"
"I'm hard and it's all your fucking fault." Kirishima chuckles as a blush blooms on his own cheeks.
"Oh really?"
"Yes, you fucking stupid sexy bastard."
"I see," the redhead snorts. "...do you want some help?" Bakugou's silent for a moment, then Kirishima can hear him fumbling with his pants.

Long story short, Kiri picks him up and braces him against a wall while he lets him fuck his throat. Bakugou cums all over his chest and makes him clean it up as payback for distracting him.

Kirishima takes a picture for him before cleaning up the mess.

Tiddies.
