Donnie x reader (tmnt)

Mutagen obsession.

( I don't own the song at the top, I just put it there because it helped me come up with the awesome chapter. Sorry for the wait, enjoy the chapter!!!!!!)

WARNING YANDERE THINKING, CONTENT!!!!!!

It's been weeks, you have warmed up to the turtles all the way, well almost all of them, you were still a little shy around Donnie because you now had a even more massive crush then before on him.

You were running to the lair, you just left your friend's house. Mikey called you and said they ordered pizza, but the new ultra pizza and he was gonna eat your piece if you didn't hurry up.
You were not gonna let Mikey touch your food or else someone was gonna die.
You were kinda getting tired but the determination of getting your food was helping you.

Suddenly you failed to notice the slippery surface under you and slipped.

(Real smooth XD.)

Everything was wet, your hair, hands, clothes. "Gosh dang I- " you couldn't finish your sentence because a exhilarating rush filled your body making your eyes twitch. You felt light headed and could hardly focus. Looking at the liquid substance you fell in, your eyes started to tear up.

What am I gonna turn into?

Is all you could think of looking at the mutagen you were sitting in, scared half to death.
You surprisingly sprinted up your suddenly weak body and tried rubbing off all the mutagen that touched you. Again you felt another rush go through your body then you forgot all about how you fell and how you touched mutagen. "Why the heck did I stop? I gotta get some of that pizza!" You yelled to yourself and started running to the manhole.

~after eating pizza~

Of course there april was hugging Donnie, him appreciating it. He should be the one hugging me. April doesn't deserve him if only I could get rid of her all the way. You smirked then realized what you were saying. Why in the world were you thinking like this!? It's like your emotions were ten times stronger.

You saw the pizza cutter on the couch and your hand was reaching out to get it and hurt April with it. Then you realized what you were doing. What in the world is wrong with me? You thought to yourself instantly forcing your hand back. Since you felt funny around the others you decided to go back in Donnie's lab and finish more homework.

While you were in there you couldn't focus at all something was making you quenched and feeling anxiety. You remembered Donnie talking about how much he liked April to you. Your eyes did a nervous twitch and you had no idea why. You drank water but it only made it worse. You were so sad it was gonna drive you insane.

But looking over you saw a can of mutagen. It looked. Delicious. Wait what!?.

That thing turns people into monsters I would never drink that. You thought to yourself. Your pencil started to shake in your hands. You couldn't control yourself. With ease you opened the mutagen container and started drinking out of it.

Instantly your eyes dilated and then went back to normal. You chugged down the hole thing. Going back to your homework you finished tons of it in less then a minute. But... How? You felt... Happy? All your fears just disappeared.

You then went up to Donnie and did something you probably would've never Done. "Hey Donnie can you come help me with my (worst subject homework?)" you were feeling very confident. "Sorry Y/N I am helping April with her science homework." You then frowned and you felt so much rage that you never felt before. "on how much April helps you with experiments I am pretty sure she doesn't need that much help, can you please just help me right now I mean your with April every hour 24/7 Donnie." You frowned and crossed your arms.

Then few seconds later you just realized what you said. Now you were embarrassed to no end. "I suppose your right common Y/N I will go help you for a little while. "

~April's pov to reader -_- )

Wow you must be getting really jealous . Hehe. I knew you had a crush on Donnie ever since I saw the vision.
If you think you can steal Donnie away from me go ahead. *smirks* (congrats you found first clue to her plan!)

~back in lab~

" so that's how you do that" Donnie said. "Thanks Donnie, now if only you were my teacher" you guys shared a little laugh. "I would probably fail you on purpose." Donnie joked and you playfully punched him in the arm.

You felt like your insides were burning LITTERLY! Why were you more emotional?

~next few days~

You have been drinking tons of mutagen and your emotions were cranked up a notch. Which didn't help you with school, other then getting your work done super fast. You were having a pleasant walk home (wait for it) until you got stolen by the Kraang again and realized all the turtles were tied up.

PLEASANT DAY !

"The Kraang shall now test how strong the earthling know as Y/N's powers are, we shall chose a friend of hers knows as the turtles to hurt the friend of hers known as the turtles." You were scared half to death and was trapped in metal bars. But of course they have to choose Donnie to hurt.
-_- .

They pointed a gun to his head and it started charging. Anger and sadness rushed through you, like a little kid who doesn't get candy. You started to nervously twitch and twitch and twitch. Surprisingly with great strength, breaking off the metal bars with anger, you ran so fast then you could before and kicking the Kraang droid in the face. All the other Kraang started shooting their guns at you, but with great ease you did back flips avoiding every ray. You untied Donnie.

"Y/N that was amazing !!! Where did you learn to do that!?" He asked amazed. "I- I don't know.. Maybe it was because someone I cared about was in danger?" You said looking down and blushing.

Then you could feel Donnie staring at you. Donnie was staring feeling a feeling he has felt for April, but this time for you.

~ I am getting tired of writing lets just wrap this up lol~

~ back at the lair~

you woke up to see Donnie worriedly looking at you, brown chocolate eyes making you smile.
" Y/N how are you feeling?" He started to check your heart beat. " I am feeling better actually, what happened?"

"Where do I start?" Donnie asked rubbing the back of his head.

~important message in bold text PLZ read for the ppl like me that normally skip the bold parts at the end, XD~

(Hey so let me just say I am sorry for making Donnie so mean to Y/N in this fanfic, but lets be honest with ourself if we ever met him it would take him a while to get over April and would love to hang out with her, you will be with Donnie but it will be a while.)
(Please comment sorry not too much romance this chapter I will add more romance would you like me to reduce with the action and put a lil more romance?????)
