- loki x f!siren!reader

warnings: angry tony? secretly dating, language. slight smut towards the end (a few words), I think that's all?

*please read all warnings before you continue*

synopsis: Tony Stark finds out his sister, you, are dating Loki.

artifact citation: this was requested by @iamcavainna. she wanted a Loki x siren!reader who are secretly dating and Tony gets mad upon finding out. please note that this request is altered, and Tony doesn't go ape-shit. also, this is my first ever siren!reader, so I hope I did well. this is not beta'd, all mistakes are my own.

however, you didn't go unnoticed by one particular man. Loki was an observer. he likes to look around to further understand his surroundings. he's seen you around before though, yet he's never actually spoke to you. that was soon to change however.

you've jumped into the ocean out of fear, some man you've seen around but haven't found the courage to talk to, and Tony stalking ahead. he of course knew of your 'abilities,' but he hasn't seen them per se. it was embarrassing. but now with a tail, webbed fingers and sharp teeth, you felt ugly.

despite being scared by Loki and your brother (because even he hasn't really seen you), you stayed near the rocks, hiding behind them and peaking out. by now you'd've deemed the guy with green swimtrunks attractive. there was no denying his beauty.

you've watched from your spot and saw how Tony and Loki made their way over, no doubt that Loki pointed you out, your face familiar despite the lack of talking you guys shared. this intimidated you. you didn't want them to see you like this. Tony knew only of the vague in what Howard did to you. you've beat yourself up for it, though, silently suffering in ways you don't want to experience again. you've ducked under the water, turning around only to see a wall of rocks. you've felt trapped. a hand was grabbing at your hair, feet kicking at you, not intentionally of course. you were bad at being a siren.

so you resurfaced. who you thought was Tony, was actually Loki. your face was only a mere inch away and when you realized this, you blushed and backed away from him. though you didn't take your eyes off of his, the blue hue luring in. just like a siren. and it was only when Tony cleared his throat you've looked at him.

with your eyes now on Tony, Loki took his chance to look at you. your tail was a marvelous shade of tan and orange, white peaking out around the fin's edges, a top to match. your nails were slightly longer than normal, not that Loki would notice right? and he couldn't help but notice how you seemed to sink beneath the water, the weight of the tail combined with the gravitational pull far too strong.

Loki, ever the heroine, reached beneath the water and grabbed your tail. you've nearly coughed on water when he did so, the nerve endings on the fin of the tail far too sensitive. "don't touch my tail!" and Loki did just that, seeing how you blushed from embarrassment, the phrase foreign on your tongue. Tony just watched. he wasn't one to speak unless giving orders. but you couldn't help and look over at him, his face sour and eyes glassed over in a threatening mood. how dare Loki touch his sister?

⎈

and that is how the pair of you started dating. more or less that is. you've talked in between now and then, and he asked you out, away from prying eyes and ears. you've loved him since then.

and although quite vague to memory, you remember that day. that day in which you described as, 'a hurricane in the ocean.'

the day was sunny, not a cloud in the sky. you sat outside with your beloved Loki, a picnic in session. you decided to rest your head on the inside of his thigh, closing your eyes as he read you a book about two forbidden lovers. how cliché. you've started to drift off soon after the second chapter, and Loki bent over to kiss your lips.

they'd've made contact if it wasn't for Tony who came running outside, yelling like a madman in a crackhouse. you jolted then, head butting against your lovers head. wincing, you looked at Tony with a questionable look on your face before looking at Loki's forehead. "what was that for you fucking prick. I was nearly asleep!"

"yeah, in Loki's lap! and he tried to kiss you, in your sleep!" Tony sounded like a child then, adding things on to creep people out so they listen better.

"that's not how it was, Tony."

"how long has this been going on? hm?" there was heartbreak in his voice. you knew that, you heard it. poor Tony. probably thought he was getting replaced.

"its- its been going on for a few months now, Tony. 'm sorry I didn't say anything earlier. it's just that, Loki makes me happy. when it's hot at night, he keeps me cold. when I-I'm bored, he does things with me. he cares for me and I care for him. 'm sorry to disappoint." you tried to hide your smile as you looked at the ground because playing the shy sister always made him feel selfish, Loki staring at your brother and likewise.

"so you keep her cold? what, you just leave the bed? and when she's bored you get back in bed with her?" Tony kept pressing all these questions and you just froze, tears welling and cheeks blushing.

"look man. you're getting backwards. on hot days like this, especially at night, I turn into my jotun form. and I don't ever leave the bed. and by bored, we don't mean that" there was a smirk on Loki's face "we mean something like this. something to pass the time. and I really do love your sister, Tony."

Tony didn't know what to think, a face once angry was now a face covered in embarrassment. does he still argue? does he give in? does he just walk away? no.

by now you're all standing up. but Tony makes quick in pushing Loki to the ground, a scowl on his face. "if you ever, and I mean ever, hurt her in any shape, way, or form, I'll kill you. that's a promise." and then he just walked backed inside, his heart on the verge of breaking. it wasn't for him, but for you, his sister. he saw how much you loved Loki, and that meant no more time for him. you were his only other family.

okay but like his hugs?

they're so welcoming and I bet they're warm too; jotun form included.

"my darling had a rough day? c'mere." and it's just warmth and muscle and safe.

and his hair!

"c-can I braid your hair loki?" and he's all shocked at first but hands you his favourite brush and comb and scrambles to find his favourite hairtie that's actually yours.

jotun form. that's it.

when he first showed you, you were scared? shocked? turned on? you saw everything; from muscle to well . . .

jotuncock.

if you though his normal form had a huge cock. wait til you meet this guy. it's bulging in your stomach, your throat, your ass.

"gonna fill this pretty pussy up, darling."

"gonna make you a mother. oh yeah, bet you'd like that. oh~ don't squeeze me so tight princess."

he's filthy.

on another note, regarding you, he'd be touching your tail.

"don't touch my tail."

"fuck off."

and you're just so fed up about it.

and he's fed up about you singing. it literally lures him in. you don't mean too, honest, but it just happens.

"you fuckin' messin' with me now, princess?"

and he has to explain why he's there and why he's angry and why you can't just stop it.

and we can't forget about Tony.

he's not okay with any of this because he doesn't want you to forget him

"piss off you fucker, I'm watching a movie with my sister."

"Tony, don't be mean."

pushes Loki extra hard when training and treats him like literal shit.

but Loki is okay with it. so long as you're happy with him vice versa.
