My omega

School

Katsukis POV

I wake up to an annoying alarm "Zuzu turn it offssssss" I say to my alpha

"one-second little one," he says as he sits up and turns it off "let's go get ready"

"for what?" I ask 

"school silly"

"Ugh I don wanna go to school then I'll have to be big" I frown

"I'm sorry little one we have to"

"hmph fine"

"I love you"

I close my eyes for a second and start to go big, after a few seconds I am fully big again.

"I love you too alpha"

He imminently notices I'm big 

And I immediately notice my diaper is wet and I'm sitting in a wet, uncomfortable diaper. "ill be right back" I tell him

"what why?"

I blush embarrassed "my diaper is wet I want to get out of it"

"oh okay"

I run to the bathroom with my school uniform and change out of the uncomfortable diaper and into my fresh clean clothes

I come out after a few minutes smiling "alright alpha I'll go make us breakfast now what do you want to eat?"

"eggs and toast please," he says as he starts to change into his uniform as well

I walk down to the kitchen and start to cook

After a few minutes, izuku walks down and sits at the table. Once I'm finished I place his plate in front of him and mine next to him, both being accompanied by a fork.

I sit and eat my food.

"thank you Katsuki"

"no problem alpha" 

Once we are finished we grab our bags and start walking to the train.

we walk together holding hands the entire way

Once on the train, we sit down next to each other and after a while dekus BFF Ururaka gets on

Most people like her, I mean she is kind and pretty but I know she has a thing for my alpha.

I know that she will smell me all over him and be jealous, even if she has another alpha already, she wants mine.

Ururaka walks over and sits on the other side of izuku "good morning Deku" she says to him

"oh good morning ururaka"

She leans in to hug him and when she smells my sent she scrunches her nose "Deku whats that disgusting sent on you"

"huh I don't know what you mean ururaka, I've just been with kacchan his sent is the only one on me" he replies

"but that's an omegas sent on you, he's an alpha," she says

"uh no he's an omega, and he's my omega" 

She laughs thinking its a joke but realizes it's not "well he's only your omega because you're in an arranged marriage, so it's okay to cheat on him you know"

"what no! I would never cheat on him!!"

"yeah yeah whatever" she rolls her eyes and glares at me 

I tug on izukus shirt and he looks at me

I give him a face that shows that uruakas making me uncomfortable so he hugs me tightly and kisses my forehead "everything is gonna be alright love, I promise."

then the train stops and announces it's our stop so we get off, me still holding izukus hand and ururaka flaming furiously behind us. we walk into school and go to our lockers to change shoes. 

Once changed we walk to class sitting in our designed seats, but I turn around and talk to deku instead of facing the board like normally.

Kirishima then walks in and immediately notices "Yo bakubro!! You seem to be in a good mood! you're even talking to midorya!"

"yeah yeah whatever shitty hair"

"language katsuki" izuku states

"sorry alpha" I look down sadly

"Wait bakubro is an omega? and midorya is his alpha!" Kiri asks

"yes that would be correct kirishima~kun," izuku says

everyone in the class gasps and starts asking questions, questions I don't want to answer.
