Chapter Text
“Loki, I’m so warm.” You whined; your skin so oversensitive that you knew the slightest touch would likely be your undoing. You pushed yourself against the far wall of the cell, squeezing your legs together to try and ease the ache between them.
You and Loki were on a mission and had been unexpectedly captured by the Hydra agents you were sent to do surveillance on. Tony had caught wind of a plan they had where they were developing some sort of serum that would create more supers.
Your capture happened so quickly that you barely had time to fight back before both of you were injected with something and thrown into this cell together. It was confusing for you because typically they didn’t like to keep prisoners in the same cell. But as you sat there, you realized that the injection they gave you was slowly taking effect, and it was freaking you out.
When Loki didn’t respond you looked up at him, finding him pressed against the corner, his eyes closed in concentration like he was in pain. You couldn’t help but notice the bulge in his pants, his length straining against the leather as his knuckles turned white from clenching his fists.
His breathing was shallow, “Stay away from me. For your own sake do not come closer.”
“You feel it too?” you asked, wrapping your arms around your middle. You curled yourself into a ball, trying to think of anything else but the feel of Loki’s skin on yours.
“I don’t know what they gave us, but… to be transparent I am trying very hard not to lose control and…”
Loki was cut off when he heard your quiet moaning. His eyes shot up, looking over at you with a wild expression. You had shoved your hand down the front of your pants, aching to get some relief. When you ran your fingers over your slit, you were shocked to find that you were already soaked with arousal.
Something inside Loki snapped, and he used his magic to yank you roughly over towards him. He wrapped his arms around you, pressing his face into your neck and inhaling deeply. Letting his tongue lick along your pulse point.
“Fuck.” He cursed, ripping your hand from your pants. You gasped in shock, looking into his eyes as he slowly sucked your fingers clean, a deep sound of satisfaction leaving his chest. “mine” he whispered, pinning your wrist above your head as his lips went back to your neck, running his nose along the space between your neck and shoulder.
You moaned tilting your head back to grant him better access, wrapping your other arm around him, pressing him closer.
He took your chin in his hand, turning your head so that your eyes met, “tell me to stop.” He said, searching your eyes for any hint of hesitation.
You looked back at him, his eyes flickering red like he was teetering on the edge of control, trying to make sure he wasn’t forcing you against your will.
You looked at his lips, full and soft and you leaned in, pressing your mouth to his.
His answering groan made you shiver as he kissed you back, devouring you like a starving man. He wasted no time prying open your shirt and laying you down, looming over you so that he could kiss down your chest. He ran his tongue over your breasts, grasping them greedily in his hands as he began to suck each nipple until they were hard.
You squirmed in pleasure underneath him, his mouth only providing half of the relief you craved.
“Please, Loki.” You sighed, taking his face in your hands, “I need you.”
His eyes widened; the irises completely red as his pupils dilated. He grabbed one of your wrists and pressed a gentle kiss to it. “Beautiful.” He said, releasing you as he unbuttoned his pants before moving to yours, yanking them down roughly before positioning himself over you.
He immediately sheathed himself inside you, making both of you cry out in relief.
He began rutting against you, soothing the ache that was persistent a minute before. His skin on yours was like a balm that calmed you. It was clear what exactly the Hydra agents gave you, but you couldn’t bring yourself to care at the moment.
“You feel absolutely divine.” He praised, running his tongue along your cheek. “Pretty, pretty human.” He murmured into your skin.
You wrapped your legs around him, digging your nails into his shoulders, “Faster.” You begged.
Loki’s jaw stiffened, and he moved a hand to your neck as he began fucking you into the floor at a brutal pace. The slapping of his skin sending electric shocks throughout your body.
You cried out as you pulled him closer, “I’m going to…”
“Come for me, little one.” He rasped, “I want to feel you come on my cock while I fill you up with my seed.”
You came with a forcefulness that you hadn’t felt before, the waves of pleasure hitting you like a truck.
“That’s it,” Loki praised, reaching down to massage your clit, prolonging your orgasm. “that’s my good girl.” He said, not letting up his pace as he came with a shout shortly after, burying himself to the hilt while he emptied inside of you.
He collapsed onto the floor, wrapping his arms around you possessively as he recovered. You rested contentedly, panting heavily as you nuzzled his cheek, giving him a kiss. He turned his head, catching your lips with his own, kissing you deeply until you felt him grow hard inside of you again, despite finishing only moments ago.
“More.” You whispered, “I want more.”
He grunted, flipping you over. You felt his essence drip down your legs as he examined you, his hand on your ass as he inspected his work.
“You look absolutely ruined, darling, with my seed leaking from you.” He cooed as you felt him positioned himself behind you, adjusting you until you felt the tip of his length at your entrance.
“I’m going to fill you again and again; I want nothing more than to embed my scent into your skin.” He continued, grabbing your neck and yanking you upwards as he guided himself inside you. He kissed your earlobe, and you reached behind you, grabbing a fistful of his hair and giving it a tug toward you until your lips found his. “I want everyone to know who you belong to.”
You couldn’t ever remember feeling this incredible, it was like he was lighting fireworks off inside you. “I’m yours,” you said, kissing him again. “I belong to you.”
He nuzzled your neck, kissing you again before he bit down hard. You cried out, the pain mixing with the pleasure in a way you didn’t think was possible. You could tell he drew blood as he began licking the mark clean, soothing the sting with his tongue. “Mine.” He growled, pushing you towards the floor, holding you in place as he fucked you mercilessly.
You clenched around him, feeling yourself come again.
“I can feel the way you hug my cock,” Loki groaned, leaning over you so that his chest was directly over your back. You could feel the blatant possessiveness and need with each of his thrusts, nearing his own finish. “So perfect for me,” he whispered, nuzzling his bite mark. “All mine.” He declared, before giving a final thrust, filling you even more.
Both of you were spent, and you protested when Loki withdrew himself. “Here,” he said, pulling you into his arms as he sat upright against the wall, cradling you to his chest.
You snuggled into his arms, feeling so safe and satisfied, completely ignoring the fact that you and Loki were still in a cell, likely being monitored by your captors.
He pressed his lips to your hair, keeping a tight hold on you as you rested your head on his shoulder, feeling exhausted.
“Sleep.” Loki said, beginning to trail his fingertips along your back. “I’ll protect you.”
You hummed contentedly, falling asleep in his arms as you felt him stroke along your skin.
***
You woke up after what felt like a long time, but were shocked when you opened your eyes and saw the inside of the Avengers medical bay and not the cell you remembered falling asleep in.
Two questions hit you at once. One, how did you get home? Two, where was Loki?
You sat up, your stiff limbs protesting as you looked around at the surrounding beds. You were completely alone, which didn’t seem right. At the very least, Loki would be there with you if both of you were rescued.
You went to swing your legs over the bed to try and find out what had happened when Bruce quickly burst into your room.
“Easy.” Bruce instructed, “Lay back down, you’re still recovering”
You did as he said, settling back into your pillow. “How did I get back here?”
“That… is a long story.” He began before he was quickly interrupted by Thor.
“You’re awake.” He said, appearing out of breath. “Bruce sent me the alert that you had woken up just a few seconds ago.”
“Why would he need to-”
“Let us explain,” Bruce said, checking your vitals before continuing. “When we realized you two had been captured, we sent out a team immediately. But it took a while to find you and when we did, they had already given you that serum.” Bruce explained, “and we found you… post activities.”
“Oh.” You said, feeling your cheeks burn in embarrassment that your team had found you naked cuddling up next to Loki after being fucked into the floor.
“Don’t be embarrassed, you were under the influence.” Bruce continued, giving you a sympathetic look.
“So, what exactly was their plan?!” you asked, “what did giving us… that, do?”
“You’re not going to like this…” Bruce began.
You rubbed your forehead, “Probably not, but go on.”
“Okay so, essentially from what we gathered, it was… a breeding program.”
Your stomach dropped, your hand immediately going to your middle.
Bruce shook his head, “thankfully we found you in time to prevent that from happening.”
“Oh my god.” You said, “that’s…”
“Wild.” Bruce finished. “They would select certain people, give them the serum and have them keep trying until they were successful at creating another super. One which would work for them, all while keeping the parents so drugged up that they wouldn’t even notice.”
“That’s horrible. I’m glad that you found us in time.” You said, shivering at the thought of being trapped and used as breeding stock. “Wait. Where’s Loki? Does he know all of this?!”
Bruce hesitated, “he does but…”
“But what?”
“I think Thor can explain it better,” Bruce said, gesturing for Thor to continue.
You looked at Thor who gave you a half-smile. His usual sunny demeanor was gone which made you even more concerned about Loki.
“When Loki bit you, what he left wasn’t just a bite, but a mate mark.” Thor explained, “it is a custom amongst the Jotunn people to give their mate a bite mark to symbolize marriage, or rather a deeper bond than that.”
You reached up, touching the mark that was in the process of healing, “oh my god. I’m…”
“Mated to Loki.” Thor nodded. “According to the old customs of Jotunheim.”
“Okay,” you nodded, taking in that information. “What does that mean, and why isn’t Loki here?”
Thor sighed, “Newly mated Jotunn’s are violent when it comes to their possessiveness over their mates. So, when we tried to take you in for medical care, he lost it. It took me and Banner quite a while to subdue him, and he’s been in a holding cell ever since.”
What Thor was telling you didn’t feel real, your heartbeat was pounding in your ears at the realization of what he was telling you. “Oh my god, is he alright!?”
“Mate marking someone changes something in a Jotunn. His brain is now hard-wired to protect and provide for you. For the first few weeks, from what I understand from the information we have on Jotunn mating practices, they are generally kept confined, doing little but eating and drinking and… enjoying their new bond.”
“And what happens when their mate is taken away?”
“The bond does not lessen; it only makes the male more frantic over time. The bonding process should be followed through with for the frenzy to clear.”
“So, you’re saying that in order for Loki to be well again, I’ll need to… mate with him?”
Thor gave you an uncomfortable nod, wringing his hands in front of him.
“But it wasn’t his choice.” You said, feeling awful that because he had been given the serum, Loki was driven to bite you.
“It wasn’t yours either.” Thor pointed out, putting a sympathetic hand on your shoulder.
You let out a long breath, devastated for Loki. For all intents and purposes, you were fine. But he was still being held in a cell, and suffering from what Thor was describing. “Can I see him?”
Thor and Bruce looked at each other, “Are you considering going through with it?” Bruce asked.
“I don’t think there’s another option.” You said, “otherwise, you said that he won’t… be well. Right Thor?”
“Correct. However, once you strengthen the bond, you will be his mate. Are you prepared for that?”
You swallowed thickly, the heaviness of the situation weighing on you. Do you ignore Loki’s mating hysteria and continue living as normal or do you accept the bond so that he can be normal again, but you would effectively be tied to Loki permanently.
You took a deep breath, trying to calm yourself from what you knew you had to do.
“Take me to see him.”
