Devil on my Shoulder - MCU

(Loki x Reader x Peter Parker)
WARNING: This story is pretty crap but idk there might be some concepts you find cool or smth? I recommend skipping the first 2 chapters if ur just here for conceptual stuff. It doesn't get good until chapter 3 or 4.

Y/n Stark.
By night, she is the superhero named Electriod. Rumoured to be strongly affiliated with Iron Man due to her nearly identical armour, she fights crime often alongside Spider-Man, both well-renowned heroes outside of the Avengers' inner circle.
By day, polite well-behaved student at Midtown High and best friend to Peter Parker who keeps every secret she has, including that she's Tony Stark's daughter.

Y/n's got a crush on Peter but, due to an old promise she made to an old flame, she's got a green eyed monster running through her veins and he'll have her loyalty until the day she dies.

Every day, whenever y/n feels something extremely negative, she can hear him whispering bad advice in her ear. And every night, when she's hidden away from the rest of the world, he comes to her and though she can't tell if he's even there or if she's just going insane, she's still hopelessly devoted to him.

Soon, it's clear that Peter and y/n's other best friend, MJ, are falling in love and as their romance progresses, more so do y/n and her green eyed monster become one and the same.

Y/n knows she shouldn't be with Loki but she can't help it. She's addicted to him. She thought Peter would've been the fairytale prince to break her curse but it seems she was mistaken. Will someone be able to save y/n or will she give in to her addiction and let her poisonous love take her over?
