chapter two - seiki

There will be smut in this chapter. I'll let you know when.

Izuku's POV

"Your awesome!" Seiki exclaimed.
My eyes widen in surprise. "You really think so?" She nods.
"Yeah! I saw you as you faught Mr. Ground zero! It was awesome!" I giggle with her.
"Izuku! Where were you?" I turn around to see dabi and tomura behind me with worried faces.
Dabi eyes what I have in my arms.
"Who's that?" He asks walking up to me. Seiki holds on to me nervously. "Izuku I'm scared..." She says. I kiss her forehead.
"It's okay seiki." I whisper. "She killed her abusive parents.
I found her alone and crying by the bathroom."
I say hugging her tightly To my chest.
"Her name is seiki she's four." Seiki holds onto my shirt as tomura
Walks up to her. I sit seiki down on the ground and she looks at tomura and dabi nervously.

"It's okay." I whisper. "It's okay seiki." Tomura murmurs. Dabi puts out his hand "we aren't gonna hurt you seiki." Seiki touches dabi's hand and stands up.
"What's your names?" "I'm tomura shigaraki. You can call me tomu or shiga okay?"
Seiki nods smiling a little. "I'm dabi" "dabee?" I giggle at her attempt at saying his name.
"Yes dabi" seiki giggles.
"Dabee!!! And shigaaa!!! " She squeals jumping into tomura and dabi's arms.
We all laugh. "She's so cute! Can we keep her?" I whine.
Dabi and tomura look at each other. "Yes" they say together.
I squeal.
"Yay!! Seiki you are now my little sister! You can call me your brother!" I exclaim. Seiki giggles "yay!!"
We took her home to live with the league.
She got along with everyone easily especially the twins.
She adores toga and me, dabi, and shigaraki.

"Big brother I like it here" seiki murmured.
I smile. "I'm glad seiki" she smiles happily and runs over to toga.
I smile holding onto dabi's sleeve.
"I'm glad she's happy" I say.
Dabi nods as we watch seiki run into tomuras arms giggling.
Dabi pulls me into his arms, and wrapping his arms around
My body.
I lean into his chest. "I'm tired" tomura groans holding a sleepy seiki in his arms.
Seiki lays her head on tomuras shoulder.
"Me too..." Seiki mumbles falling asleep. We all look at her with love in our eyes. "Little seiki, goodnight" tomura carries her into my old bedroom and lays her on the bed. Toga and Todo left to go home so it was only me, tomura, dabi, and seiki.
I walk to dabi and tomura room and sigh opening the door.
"Dabi where did-"

I blush seeing dabi and tomura lying on the bed shirtless and staring at me.
"Come here" dabi says. I obey walking up to the bed

⚠️Smut warning! ⚠️
I crawl across the bed and sit on dabi's lap.
Tomura kisses my neck leaving hickeys and love bites all over my neck and collar bone.
I moan, softly kissing dabi.
"Your such a good boy~" tomura whispers in my ear.
I shiver a little. Moaning at their touch. Tomura lays me down on the bed so I am under the two.
Dabi and tomura begin sliding off my clothes while kissing my neck.
"Please...!" I moan clutching dabi's arm. "Give it to me... Please!"
Dabi and tomura smirk at each other.
My breathing gets heavier as tomura slides off my shorts and shirt.
'we aren't going back after this...' I think.
Dabi slides his hand down to my dick and slides his hand up and down. I moan out loudly"shhhh... Remember seiki is in the other room." Dabi jerks me off faster. I try to hold in my moans but fail. Tomura kisses me muffling my moans.

Dabi's POV
His moans were intoxicating...
I jerk him off faster watching his face turn. I know seiki is in the other room but I need to make him ours right now.
"Dabi~" he moans. Tomura looks at me and I nod.
I position my fingers at izuku's entrance and look at him for permission.
Izuku nods covering his mouth and closing his eyes tightly.
I slowly let go of izuku's dick which was dripping pre-cum off of the tip.
I push my finger into his entrance and izuku cries out in pain.
Tomura touches izuku's face gently with three fingers and izuku looks up at him with tears in his eyes.

"It...hurts!" He cries. I wait until he calms down so I could start thrusting my fingers in and out of his tight space.
"Mmm..."he moans. Tomura kisses izu deeply drawing his attention away from the pain.
At this point I could fit three fingers inside of him.
I pull out my fingers and position myself at his entrance with tomura behind him.
"Ready?" He nods. Tomura and I push into him slowly.
Tomura covers izuku's mouth so he doesn't scream.
"Hurts...!" Izu cries. We keep pushing until we are fully inside.
His insides were holding on to me tightly And were really warm.
Tomura looks at me and I nod.
We thrust slowly in unison. Izuku moans in pain and pleasure.
"More...! Faster...!" He moans.

Izuku's POV
It hurts but the pain feels amazing...
Am I a masochist?? No... I can't be.
Tomura and dabi thrust faster than before, ramming straight into my prostate. I start to go crazy begging for them to go faster.
"I'm... Gonna cum!" Dabi moans. "Me too... " Tomura says.
I grip onto their shoulders as hot liquid flows into me. I stick my tongue out like a dog in heat.
"So... Hot...!" I collapse onto the bed exhaustedly as the two pull out of me.
I close my eyes and everything goes black.

(This is my first time writing smut so don't hate on me that much!)

The next morning~
Izuku's POV
I open my eyes slightly to a bright light shining in my face.
My body hurt like hell.
I try to move and a pain shoots through my lower half.
I try moving again only to fail and be pulled backwards.
"Calm down it's just me." Dabi says sleepily.
I smile looking straight at tomuras sleeping face.
I turn around and kiss dabi gently on the lips.

"What a night"
