Todoroki knows that he can be slow at times. Especially with his feelings. It’s what happens with Midoriya’s new hero costume that hugged his backside so sinfully tightly. In the beginning, he doesn’t know why it bothers him so much.
When it dawns on him, it’s too late to shove the feeling to the deepest pit of his heart.
He has an embarrassing, sappy crush on Midoriya. And his new costume doesn’t help. It stretches out over his cute bubble butt, begging Todoroki to slide his palms over it and squeeze. He wonders if the cheeks would relent and let his fingers dug into the muscle or if they are rock hard.
Well, he is.
To make matters worse, Midoriya is always moving: squatting, jumping, getting on the ground to crawl right in front of him in a dingy tunnel. Todoroki wants him to come to an abrupt stop so he could plant his face between the plush cheeks.
It never happens, but a boy can dream.
And he notices that he isn’t the only one who’s eyes linger on Midoriya’s lovely ass. Uraraka bites her lips as her eyes lavish the sight. Iida’s face is hidden behind his mask, but Todoroki knows where the eye slit is directed. Kaminari is shameless – he slaps Midoriya’s ass.
“What’s your secret, Midoriya? Squats? You’re looking mighty thick.”
Midoriya blushes and stammers up a storm about diet and cardio and muscle training.
Todoroki knows he has to do something. Not that he is jealous, oh, no. He would never! But it’s distracting. Bakugou walks into Kirishima’s back when Midoriya’s doing low lounges before practice.
That bubble butt is going to be the death of his. Todoroki can’t do anything against it – but he can make others stop ogling Midoriya so indecently—
“You’re drooling.” Yaoyorozu gives him a napkin and a look.

“Oh, shit.”
Todoroki looks up to find Midoriya struggling to pull his pants up – he’s been getting thicker from practising his shoot style, thighs growing stronger and ass… bigger. He is wearing briefs, at least, but as the pants slide up, they leave nothing to the imagination. Except for the feel. Todoroki is happy they’re alone in the locker room.
“Midoriya, have you considered changing your costume?”
“Huh?”
“It seems you have outgrown it.”
“No, no, it’s okay. I can fit my protective gear around it.”
When he turns away, Todoroki swiftly licks his lips. He should just burn the damned pants. Nobody would know.
“What if they rip?”
“This is a polymer blend specifically for costumes. They won’t rip, don’t worry!”
Worry is the furthest from Todoroki’s mind.
“Do you have enough range?”
Midoriya tilts his head to the side but humours him. He squats down, stands up, pulls one knee up.
Todoroki wants to know how far he bends.
“It doesn’t look comfortable.” His own pants don’t feel comfortable. “Too… tight.” Khm.
“It’s fine, look.” He pinches the material and pulls it away from his thigh, only to snap it back. “Plenty to give.”
Todoroki is running out of options with all his blood rushing out of his brain. “Wait, is that a hole?”
“Wait, where?”
“Turn around, let me—”
Midoriya, obedient as ever, turns and twists his body to try and look. “Where is it?”
“Yes,” he lies. “Right here.”
“Shoot, really?”
“I think you should change it. I have sweatpants you can—”
“It’s okay, I have backup pants.” Midoriya peels the pants off, then puts them on the bench. “There they are.”
He pulls out a pair of shorts and Todoroki’s heart skips a beat.
“Damn, they are shorter than I remembered. Must have shrunk in the machine.”
Todoroki’s mouth dries out as he watches Midoriya put on booty shorts. When he bends forward to pull his leg guards up, Todoroki can see the bottom of his ass peek out. He can count the freckles on the cheeks. It is positively indecent.
Midoriya turns to him with a mischievous grin. “You were right, Todoroki. These are way more comfortable!”
Midoriya knows that he is suffering. Oh, Todoroki is so fucked.
