Katsudeku Fluff N Stuff

Yandere Midoriya

A/N:
I know I said I'd update last night, but it was 1am and I got distracted by bnha animatics on YouTube, so hopefully this one shot is good enough to make up for the day late update. Enjoy ~

Izuku was normally a ray of sunshine. He was my happy little green bunny that I would chase to the ends of the earth just to be with.  His small stature with chiseled  muscles and  perfectly placed curves drove me wild with desire. His plump pink lips were a craving that I could never get rid of. Best of all, his soft green eyes would lure my heart in an angelic embrace.

The Izuku on top of me now was anything but angelic. 

His freckles were hidden under stains of blood, his teeth were biting into his bottom lip, turning it to the same shade of red, his eyes were filled with not the normal lust and love I knew, but a lust and madness that I could never imagine.  

"Kacchannnn." Izuku whispered hotly into my ear, punctuating the end with his giggle. It sounded just like the normal Deku giggle that I absolutely adored with every fiber of my being, making my head spin in confusion.

I'm dreaming, that's it. Yeah, I'm dreaming. My sweet little Deku is cuddled underneath me and we're back in our bed. Yeah, this is nothing but some fucked up kinky dream of mine. Maybe I need to lay off of the hardcore stuff for a while-

"Ah!" I yelped as my thoughts were cut off  as Izuku licked over the sweet spot of my neck and took a deep, yet soft, bite.  His face moved directly in front of mine, our lips centimeters apart, noses  touching, and Deku's hand holding my chin in place.

"Kacchan, with all of your staring into space, I'm starting to think you're not interested in me." The small boy pouted. "You didn't need to care about them, you have me, and I have you. We don't need anyone else."

My heart stopped as I remember who they were. All of my friends- Denki, Kirishima, Momo, and the people I used to hang out with as a child.

They're all lying dead in the next room.

This isn't a dream!

"I-Izu, baby, w-what happened?"

"What happened?! WHAT HAPPENED?!" Deku yelled, lust leaving his eyes and the madness taking over. He got off of the bed in a display or anger, going to each corner of the bed and tying the ropes that connected my hands and feet to bed posts even tighter.

Shit, shit, shit, shit!

"What happened was, they tried taking you away from me! Momo did nothing but flaunt her chest to get your attention, Denki stole you away from me to hang out all the time, and we BOTH FUCKING KNOW KIRISHIMA WAS IN LOVE WITH YOU!" He yelled in a furious manner. His face softened as he calmed down and crawled gently over the bed, stepping over the ropes, and cuddled next to my body. 

He makes it so hard to believe he isn't really my innocent bunny.

"Izuku, I d-"

"DEKU." He said, cutting me off. "You always call me Deku, I don't want you calling me by my name now while you're trying to make up to me."

But that only makes this so much more real.

"Deku, no one could have ever taken me away from you. I love you with all of my heart." I spoke, turning my head to look at him. I expected to see a smile, possibly tears in the boy's eyes. Instead, I was met with a coldness that made me shiver.

"Then why did you hangout with them."

"Kirishima an-"

"Not them, you fucking idiot! I already explained my motives for them! Fuck, you're the most amazing person in this world, but you're really trying my patience." He said while turning his face into my chest, his arms wrapping around me tightly, but not in a loving and comforting way. I could feel the malice behind the tight squeeze, his sharp fingernails cutting into my,  and I can only assume drawing blood.
"You... you hung out with them. The people from our childhood."

"Deku, I don't see the problem with that! They were your friends too! There was no need to kill them! There was no need to murder anyone! Oh- fuck!!!"

Deku's nails slashed my sides as he threw himself on top of me, straddling my waist and pushing down all of his weight. His hands shot up to my throat and applied a deep pressure, only faint whisps of air making its way to my lungs. I gasped and thrashed, but I couldn't throw him off of me with my limbs tied.

"Oh, Kacchan." He giggled madly. My vision was becoming blurry, spots appearing in front of my eyes. Izuku licked down my chest and bit at the skin. "It really is such a shame you said that. I was hoping that you'd just understand so that we could have rough sex and make up."

"D-deku..." I tried speaking, but it came out a voiceless whimper.

"Shh, I want the last words to come out of your mouth to be that you love me. " Deku spoke, tightening his grip around my throat. "You chose the people who you used to bully me with over me. How was I supposed to feel about that? And then the you made even more friends, which meant you were giving away more pieces of your heart to them. I didn't like that. I am the ONLY one who is supposed to have your heart. I tried, I tried so FUCKING HARD to stay the cute little bunny you love. I dressed nice, I cooked, I cleaned, I was affectionate, and I acted just like the little slut you love to be rough with and fuck whenever and wherever you please. I love you, I love you with all of my heart, Kacchan. But I snapped because one tiny little bunny can only take so much before they're done with shit. If only you had understood that it was only supposed to be us.  But if I can't have you to myself, then no one can."

My eyelids refused to stay open and fluttered shut. My head felt full of air, and the last thing I felt was pressure upon my lips as my Deku kissed me one last time.

"I l-l-love you, Deku...."

"I love you too, Kacchan."

I hope you enjoyed my first Katsudeku One Shot! Please note that the more requests I get, the more one shots I'll write! I have some ideas of my own, but this is mainly a Katsudeku filler while I have writers block for the other Katsudeku story I'm writing. (Seems like I have a favorite ship, huh?) Stay tuned for the next update:
