Tomura and his Pet

Instinct

Izuku felt an impending doom as it ate breakfast beside Master. Master had a giddy face and was glittery, rubbing its back. It felt weird knowing Master would be gone after its walk and would be gone for a day. It didn't want to be alone, never again. However, it trusts Master to come back safe and sound.

However, that didn't stop its fear from bubbling up. It didn't feel good about Master leaving and doing whatever he was going to do. It knows it's essential, and Master needs to be there, but does he? He can stay with Izuku and play with it!

"What got you frowning?" Master asked it as he twitched. Izuku remembered there was a thing called coffee that causes you to be energetic. Perhaps that's why Master is jittery. It did see him drink out of a mug earlier.

"Oh," Izuku said, shaking its head. It gave Master a beaming smile before finishing up its meal.

Master hummed, shrugging. "Finish up now. I'll be in the bathroom getting ready." Izuku watched as Master got up and went inside the room. It tilted its head, odd. Master never leaves it while eating; he makes sure to stay with it until every crumb is licked up. He wants Izuku to get all its nutrients and finds it sexy to watch it lick the bowl.

A splash of noise echoed from the bathroom, notifying Izuku Master was showering. Izuku remembered a few times when Master went in the shower, but every time, he asked Izuku to play with its cock and make noises. Those times were rare, making it rarer for him to have a shower.

Izuku finished its food. He nudged the bowl beside the water one and sat up. Master is going to take a little while, and it has to wait for Master to give it an order. Izuku sighed; it flopped on its side and rested its head. It stared at the door as it waited for Master to come out.

He came out soon after in a towel. Izuku shot up and smiled. Perhaps Master will ask it to play with itself now! Izuku watched as Master picked up the bowls and dropped them off in the wardrobe. He pulled out black clothes with hands?

Izuku was startled as Tomura pulled out multiple hands (Izuku wanted to count how many there were, but it lost its ability to do maths ages ago) and a red band. "Izuku, go play with your toys." It was grateful that Master noticed its fear and allowed it to distract itself.

It picked up a rabbit plush and tried to continue its game. However, every so often, it looked back to see what its Master was doing. Izuku was staring at Master as he changed into his outfit. It couldn't think of a word to describe someone's body and wished it could. Master appeared to be flawless.

The structural placement of his muscles and bones is brilliant. Master moves in such a way that Izuku wants to beg for his cock. It didn't take long for its cock to start heating up and filling its pants. Master tucked his black clothing in and looked at it.

Izuku snapped its head back to its toys, praying Master wouldn't be upset for disobeying a command. Surprisingly, luck was on its side as Master went back to getting ready, though he was smirking. Izuku shook its head as it tried to think why Master was grinning. Perhaps he found it funny that it was looking at him.

Izuku went back to its toys for a little bit, right until Master cursed. It sawnMaster ng to grab a pale hand from the ground and place it on his face. Izuku shivered as Master adjusted more hands on his body, a smirk covering his face.

He attached a red bar to two hands from another one and placed them on his head. Izuku wanted to duck and hide. It wasn't scared of Master. However, the hands spooked him. As if each hand could come alive and hurt it, either through slaps or spanking.

Master left it alone to show the GrandMaster and Kurogiri his outfit. Izuku waited by the door as it knew a walk would be imminent. As soon as Master comes through the door, he will walk it. Izuku had to adjust its pants so that its cock didn't rub against the floor through its pants. Its cock didn't seem to want to deflate, despite the fact that it was certain it would after seeing the hands. However, this did not occur. It has become more difficult.

After its walk and a scolding from Master (for its cock being hard), Izuku was saying goodbye to him as Master started to slip on his running shoes. He stuffed his phone into his pocket and kneeled. "I'll be back, okay?"

Izuku whimpered as he leaned into Master's hand. The bad feeling returned, twisting in its stomach. It made it want to hug Master and never let him go. Izuku felt compelled to defend its Master. Master would be hurt if it didn't. It was necessary to prevent Master from leaving. It doesn't mind getting punished (as long as it's not in the room) and will be punished if it means Master will be safe.

"Don't go!" Izuku yelled, adrenaline pumping through its veins.

Master stilled his hand and went silent. "Excuse me?"

"Don't go, Master! You'll be hurt! Stay with me!"

Master only rolled his eyes and pushed Izuku's head down with his hand, crushing its head against the floorboard. Izuku whined, attempting to struggle.

"You don't know what you are talking about." Master slammed Izuku's head back into the floor with aggression. Izuku felt its vision spin as black dots pop into its peripheral vision. "You're a bad pet."

Izuku yelped in response to the insult, guilt coursing through its veins. It wanted to argue that it wasn't. It was simply attempting to protect its Master. Its plan to receive punishment while Master stays becomes dumber by the second. Master would not listen; he never has. He acts on his own initiative and never succumbs to guilt-tripping.

Izuku really is a bad pet. It can't even listen to a basic command. Master was being so kind recently, and now, Izuku repays the kindness with bad behaviour. "I'm sorry!" Izuku apologizes, tears streaming down its cheeks. "I want you safe."

"What makes you think I won't be? Hm? What makes you think I'll get hurt?" Master shoved Izuku to the ground and kicked it in the back. Izuku whimpered, laying down as its back and head pulsed in pain."I don't know," it whispered.

"You don't know? Tell me Izuku, why did you yell?" Master's voice became quieter and quieter as if he was trying to match Izuku's voice. Izuku shivered. "Bad feeling."

"You have a bad feeling about me leaving?"

It nodded.

"God, you're so fucking stupid. You just want me to stay here, isn't that right?"

Izuku shot its head up. "No! N-never! I-I want you to be s-s-safe! I m-might be a t-tad upset."

Master narrowed his eyes from above, shaking his head. "I'll punish you when I get back." Izuku whimpered as Master didn't even bother to pet Izuku and left the room with a slam.

Izuku's breath wavered from its spot. Guilt consumed it as the realisation of Master going to be gone for a day came forward. On a survival spectrum, how will it eat? How will it use the litter box? How will it survive without Master?

A little voice told it that it had done it before, and it could do it again. Which hurt, but it's the truth. Izuku can manage. But first, it needs to help Master.

To make Master's life so much easier, it will gather the punishment supplies for him so that he can quickly punish it and get on with life. Sure, it's a tad selfish that it wants the punishment to go quickly, but who could blame it? Pain sucks.

However, the pain is necessary. Now it knows to never question Master.

Izuku slowly rises from the floor and drags itself to the wardrobe. Just the thought of pain made it want to run and hide under Master's bed. It wanted to please Master, but it was also a coward. Pushing itself forward figuratively, Izuku used its mouth to pull the door open to the wardrobe and push itself so that it was kneeling and putting its weight on the furniture. Nudging a few punishment items away, it bit the handle part of the whip and pulled it out. It closed up the wardrobe and brought it to Master's bed.

Izuku knelt, dropped the whip on the bed, and sat back down. Even though it was at the foot of the bed, the punishment tool was directly in the center. In any case, Master will notice it as soon as he walks in. Izuku returned to its bed and curled up against the fabric.

Master will be here soon; all it has to do is wait.
