Work Text:
It wasn’t often that Shoto allowed himself to indulge in the things he enjoyed. There weren’t many things he enjoyed, anyway, so it didn’t matter much to him.
The list of things he liked was very small and was exclusive to two things. Only two.
Soba, and Izuku. ( Shoto’s boyfriend .)
Recently, ( though, if he was being honest, this has been brewing for a while now ) Shoto’s discovered something else he enjoyed.
Touching Izuku’s butt.
In all seriousness, he had no idea where the sudden urge to touch his boyfriend's butt even came from, but he wasn’t complaining. Not at all.
Shoto enjoyed touching. Izuku’s butt was very soft and squishy. Like dough, but with muscles buried underneath a layer of fat.
( Oh, jeez .)
The first time Shoto happened to touch Izuku’s bottom was while they were in Izuku’s dorm room, sprawled out on his bed.
Izuku had been laying on his stomach, forearms braced on the mattress while he played some sort of All Might themed rhythm game on his phone. Naturally, in the position he was in, his back was arched, and left really nothing to the imagination.
It was at that very moment that Shoto realized his boyfriend had a very plump bottom. About as round as two decently sized bubbles. It looked almost soft enough to use as a pillow.
Shoto was a theorist at heart, so of course he had to conduct some sort of experiment to prove this new theory of his. He told himself it was for some sort of science that he did not know the name of.
Butt science, his brain had supplied. Butt science sounded credible enough.
So, with that in mind, Shoto, very suddenly, leaned backwards far enough until the back of his head inevitably hit his boyfriend's bottom.
It did not take long for Shoto to evaluate his findings.
Izuku’s butt could be used as a pillow.
“Shoto…?” The owner of the very comfortable backside spoke, his voice lilting upwards in question.
Shoto hummed. His neck felt incredible.
“What’re you doing?”
He dwelled on the answer for all of two seconds before blurting, “Science.”
Izuku doesn’t question it. Not really.
“O...kay…?”
Shoto hummed once more, and the conversation ended there. The last thing he remembered from that day was waking up on a pillow, and finding that Izuku’s butt was far more comfortable than a cushion.
It all went downhill after that first occurrence with Izuku’s butt.
Everytime he was in the same vicinity as his boyfriend, Shoto would either stare at (depending on how far Izuku was from him) or touch his butt. Embarrassingly enough, Shoto made it his mission to always be right next to Izuku whenever they did hero training, just so that he had better access to his bottom.
Staring was okay, but it was also distracting. He’d almost gotten caught numerous times by Aizawa sensei and it would be far worse than just humiliating if he had to explain the reason why he was blatantly staring at his boyfriend's butt.
So he had to compromise, of course.
Standing next to Izuku in training wasn’t an unusual thing on its own. What wasn’t so usual was Shoto’s wandering hands.
Izuku had let out a very loud squeak when he had first placed his left hand on his butt. It only occurred to him afterwards that maybe he should’ve warned Izuku— or at least asked if he could beforehand.
They were standing behind the rest of the class, so nobody could actually see what they were doing, but it was still embarrassing when a few curious heads turned around to glance at them with arched brows.
“Shoto, wh-what are you doing?” Izuku whispered, his eyes glaring at him through his peripheral vision.
His hand doesn’t move away. He doesn’t want to tell the embarrassing truth just yet. He’d rather save that for the dorms, or somewhere where there weren't many people around.
“My hand is cold.” He lied. It was a really bad one. Though, he never said he was a good liar.
Izuku stood silent for a moment, probably taking the time to process the idiotic thing that had come out of Shoto’s mouth so effortlessly.
“Your… left hand… is cold ?” He enunciated, disbelief leaking into his words.
All Shoto could do was nod. He wouldn’t let himself be caught in the lie he created. He told himself he would straighten everything out later. Now was definitely not the time.
“Somehow I don’t believe you.” Izuku mumbled, squirming in his spot. Shoto’s hand was relentless.
“Believe it, baby.” He replied, something he had heard in a movie once. He’d always wanted to say it, and now seemed like the perfect chance.
Izuku let out another squeak, and not only did their classmates turn their attention onto them, Aizawa sensei shot them a dirty look from the front of the class.
Caught.
“Midoriya, Todoroki, do I need to separate you two like children?”
Shoto deadpanned. “No.”
Izuku replied with a nervous, “N-No, sensei!”
Aizawa sensei’s eyes glowed red. “Then stop talking .”
Shoto nodded, and Izuku let out a string of apologies. Clearly one was feeling more guilty than the other.
When the attention was finally off of them, Izuku snatched his hand away from his butt, and then proceeded to scoot an inch away from him. He was pouting, and his arms were crossed over his chest; Izuku was upset, if that wasn’t obvious.
Shoto was gonna get an earful later.
The urge to touch Izuku’s butt didn’t falter, much to Izuku’s chagrin. He didn’t necessarily hate whenever Shoto would reach over and place a warm or cold hand on his bottom, but Shoto could tell it embarrassed him.
Even then, Izuku never asked him to stop. He would only ever ask why and Shoto would always come up with a halfhearted lie.
Since Shoto’s started touching Izuku’s butt, there was another theory he wanted to test.
How soft was Izuku’s butt exactly ? There was only one way to find out. Shoto would have to take one for the team and… squeeze Izuku’s butt.
He really didn’t want to, but since it was in the name of science, he really didn’t have much of a choice. This had nothing to do with him. At all.
Shoto waited until they were alone to conduct his experiment. They were in Izuku’s dorm again, laying down on his bed. Izuku was playing another game on his phone, on his stomach, back arched.
Shoto saw an opportunity.
Sitting besides Izuku, he slowly reached out a hand, his eyes zoned in on the butt he was about to grab hold of.
Just before the tips of his fingers could brush against the fabric of Izuku’s workout shorts, a hand shot out and grabbed his wrist, holding it firmly.
Shoto barely flinched, staring down at their hands with a blank look on his face. Izuku flipped over onto his back, still clutching onto Shoto’s wrist with a suspicious look on his face.
Caught. Again.
“What do you think you’re doing?” Izuku squinted.
Shoto feigned ignorance. “What are you talking about?”
“Don’t play dumb with me!” Izuku pouted. “When are you gonna admit to what you’ve been doing these past two weeks?”
Oh no.
“I’ve done a lot of things in the last two weeks.” He replied, nonchalant.
“ Shoto .”
He blinked. “Please be more specific.”
Izuku suddenly sat up on the bed. “You’ve been… touching my butt! ” He whispered towards the end, dangling Shoto’s wrist in his hand as his cheeks blossomed with color.
Shoto huffed. Whatever. He’d been caught. It would’ve happened sooner or later.
“I have.”
Izuku choked, probably not expecting the blunt honesty.
“Wh-Why?”
Shoto scratched his cheek with his free hand. “Because… I like touching it.”
Izuku’s face exploded with even more color. “ Wh-Why? ”
“You just have a nice butt.” He shrugged, suddenly shameful. “If it bothers you then I won’t touch it anymore. I-I know I never asked if it was okay before.”
Izuku shook his head. “N-No! It’s not that i-it bothers me— I was just… confused I guess.” He giggled shyly. “I didn’t know you were a butt guy, Shoto.”
Frankly, he didn’t know that about himself either.
“I only like your butt.” He replied, pushing himself onto Izuku’s chest until they both fell backwards onto the mattress.
His boyfriend giggled. “Well, I sincerely hope you aren’t going around touching everyone’s butt.”
Shoto shook his head. “No. Only yours.”
Izuku laughed heartily, his arms wrapping around Shoto’s waist. “Fine, but next time, give me some sort of warning so I don’t make a fool out of myself in front of the class, okay?”
Shoto nodded against his chest, snuggling further into his neck. “Right. Sorry.”
Soft lips pressed kisses onto his head. Shoto preened under the attention. This was something else he enjoyed. Having Izuku’s attention all to himself.
Though, at the end of the day, what he loved and enjoyed most in the word was Izuku.
Just Izuku.
