Chapter Text
When Asgard had been destroyed and the survivors had founded New Asgard in Norway, Loki could have joined them there. But, even though he’d fought alongside Thor against Hela at the Battle of the Bifrost, it had been he who’d resurrected Surtur the Fire Demon, and many Asgardians held him responsible for Ragnarok. So, when Stark had offered him sanctuary in the Avengers Complex, he had accepted. It would make things easier on Thor, too, if he stayed away for awhile.
For now, Loki was captivated by the man they called Winter Soldier. He’d been watching Barnes for several weeks, since Stark had had a change of heart and brought him back to the Avengers Complex from Wakanda to complete his recovery. It wasn’t just the Vibranium arm, although that was undeniably part of it. The power of that arm drew him like a moth to a flame. He was obsessed, but he was also fascinated with the man himself. Their histories were similar—both had been under the influence of someone else when they’d killed people and done their worst, and they’d both been scarred by it. They were both trying to earn the trust of people they’d hurt. The few times he’d spoken to Barnes, he’d felt they understood each other—at least, better than anyone else did.
Stark had even asked them to accompany him on one occasion when he was called out. When a group of white supremacists had taken over a high school and a bank at the same time, he couldn’t be in two places at once, and he figured that was the terrorists’ plan, since the Avengers had broken up. Loki had teleported Barnes and himself into the bank while Iron Man had dealt with the school. They’d managed to take out every one of the thirteen terrorists at the bank without any loss of life of the fifty-seven hostages. Unlike Stark, however, neither Barnes nor Loki had any ethical qualms about killing when they deemed it necessary, and they were ruthlessly efficient. Stark knew they had to be used only when absolutely necessary until they learned a little restraint.
So, they were trying, and even gods and super-humans had to train. Thor spent most of his time in New Asgard now, and the only people available to Loki were too fragile for him to get much out of their sessions—except for Stark himself—and even that was only when he wore the suit. But, now...Barnes. He and that arm were as close as Loki could get to a truly worthy opponent, so he accepted without hesitation when Barnes invited him onto the mat.
“Don’t worry, Odinson. I’ll be gentle,” Barnes grinned.
“Fucking arrogant mortals,” Loki muttered to himself.
It was a good match, and it was exhilarating for Loki not to have to hold back too much. He knew Barnes still wasn’t in top form yet, but once he had the mortal pinned under him, he’d felt the hidden power and strength in that more-than-human body. It might even equal his own. They were nose-to-nose on the mat and Loki put his lips to Barnes’ ear.
“I can help you, Barnes. I can get you back to where you were. Better than you were, in fact.”
Bucky was more than aware of the god’s body pressing down on him, and the fact that they were bare-chested. He felt Loki’s heart beating where their skin was in contact, and he could swear that heart beat a little faster when he bridged his hips upward, trying to roll Loki off him. He wasn’t able to budge the god at all, so he tapped out. Loki rolled off, offered him a hand, and Bucky looked up at him quizzically.
“Why would you help me? You’re not exactly known for being a benevolent god.”
“I like you, Barnes. By Asgardian custom, we’re Shield-Brothers now, and it isn’t as if I have a lot of choices here for sparring partners.”
“Fucking arrogant gods,” said Bucky, most definitely not under his breath, as he accepted the hand up.
“Meet me in the common room in twenty. This is going to cost you a drink. Maybe two,” grinned Loki.
Bucky’s mind was working overtime while he showered. Could Loki really do what he implied he could do? What did he want in return? Everyone knew Loki never did anything without some scheme or plan behind it. The thought of how the god’s skin felt against his made unbidden thoughts cross his mind, and his cock twitched involuntarily.
Stop it, Barnes. Loki has no interest in you.
But, then again, he remembered many times looking across the room and finding Loki’s eyes on him and not looking away.
He found the god in the kitchen, waiting for him with two drinks in hand.
“I wasn’t sure how you’d feel about Russian vodka, considering your history, so I thought you might want to try my favorite Swedish stuff.”
Bucky took the drink, tapped Loki’s glass, and tossed the shot down.
“Not bad. One more?"
“Afterwards. You’ll need it. Now, sit here and relax.” He pointed at the sofa.
“Don’t move and don’t be surprised if you feel a fairly intense burn. But, most importantly, don’t punch me. You might actually do some damage with that thing,” he said, nodding at the cybernetic arm.
Bucky sat on the couch and took a few deep breaths in an attempt to relax as Loki knelt in front of him and settled between his knees. Turned out that was the exact opposite of relaxing and sent a bolt of electricity straight to his cock, so when Loki spread one big hand on his chest and one on his thigh, he had to shake his head to clear it.
“Something wrong, Barnes?”
“Umm...no. Just clearing my mind.”
Loki smirked faintly and continued. Within a few seconds, a green glow appeared on his hands and misty tendrils of green snaked their way into Bucky’s skin.
Shit. He's not kidding. It burns like fire.
It was all he could do to sit still as the fire spread throughout his body, and he must have sworn in Russian, because Loki shot him an amused look. It lasted half an hour and felt like an eternity, but all the years of damage and abuse his body had been through started to dissolve. It was such an incredible feeling, he briefly wondered if his arm was growing back.
Loki pulled his hands away and wiped sweat off his forehead, slumping back slightly onto his heels.
“How do you feel now?” That had taken a lot more out of him than he’d anticipated. There had been a lot of damage.
“Fucking fantastic! How—never mind. Magic—got it. I had no idea how much of me hurt until it didn’t. I don’t even know what to say. Jesus. Thank you.”
His eyes were glistening with tears of gratitude, and he offered Loki a hand up.
“You’re welcome.”
Loki stood up a little shakily and made his way to the kitchen, where he poured them each another drink, sat down next to Bucky, and let his head relax back onto the sofa. His eyes closed and he seemed deep in thought.
“There’s nothing I can do for your mind, Barnes. We’re both stuck with our demons and nightmares. I’m sorry.”
Bucky shrugged and leaned in until his lips were nearly touching Loki’s ear.
“I owe you. Just tell me what I can do in return. Anything. Name it.”
“The only thing you owe me is not breaking when I drop you on that mat. I did myself a favor, that's all, so I won’t have to worry about you so much. I’ll see you tomorrow. That took quite a bit out of me. You were more of a mess than I realized.”
He smiled and winked, but didn’t mention the little tracking spell he’d put into Barnes at the same time. It was harmless; maybe he’d bring it up later.
*****
It couldn’t help but bring a smile to Loki’s face when he saw how excited and energetic Barnes was the next day when he appeared in the gym.
“Ready, Odinson? I feel like I can kick your ass today.”
“I look forward to your attempt.”
The human came close several times. It was a much harder-fought victory than it had been the day before, but the end result was the same because a thousand years of practice mattered. Loki pinned him to the mat, faces a few centimeters apart, eyes meeting. A drop of sweat dripped from Loki’s chin onto Bucky’s upper lip, and Bucky’s tongue swiped slowly across it.
“Come on, Odinson. I know there’s something. What do you want from me?”
“Ah, that’s a different question. You don’t owe me anything. But, I do want something from you.”
“Name it.”
“What I want...what I want from you, Barnes...is everything. I want to inhale your scent. I want to taste your sweat. I want that metal hand around my dick. I want your cock in my mouth and your cum on my tongue. But, most of all, Barnes, I want to bury my cock so deep and so hard in that perfect Midgardian ass that I can’t remember my own name.”
A little smile ghosted across Bucky’s face. He’d been right, after all.
“Give it a second,” he said, and shifted under Loki so his pelvis pushed up into the god’s. The hardness there was unmistakable, and Loki grinned.
In a flash of green, he was flat on his back in Loki’s bed, with Loki standing over him. He vanished the human’s clothes first, then his own, and Bucky was wide-eyed as he swallowed hard looking at the god in front of him. He’d always thought Steve had the perfect male body, but Loki...he was so different, yet still absolutely gorgeous. All long, lean muscle with skin like a porcelain doll, black hair a little matted with sweat and pushed back behind his ears, and a predatory grin that was all white teeth. And, that cock, well, it didn’t get better than that. Long and thick, but not really excessively so, by human standards. He had honestly been a little worried about that, what with the whole god thing, and there was already pre-come leaking from the tip. Sex with Loki? Maybe not his smartest move ever, but then, it had been awhile since he’d done something reckless, so it was probably time.
Loki was almost salivating gazing down at the ex-soldier stretched out on his bed. Perfect proportions, muscles bigger than his own, expressive blue eyes, the light glinting off his sweaty torso, and a gorgeous cock that was already hard for him. And that arm...it did something to him. The knowledge that it actually could hurt him made his dick ache in the best possible way.
Loki slid his way up the body of the man under him, hard cock dragging along the firm muscle and soft skin. He kissed and sucked the sweaty neck, tasting the salt and inhaling the pheromones, and Bucky made a little whimpering noise at that.
“You have no idea what your scent does to me, mortal. Human, but different—more. It’s intoxicating—straight to my dick like nothing else has ever done.”
He grabbed a handful of hair and kissed him, a slow, deep, possessive kiss, and Bucky tasted his own sweat on Loki’s lips. The god lingered on the thrum of the jugular vein and felt the pulsing of that superhuman heart beating so close. He palmed Bucky’s rock-hard erection, bit down on his jugular, and was rewarded with a loud moan.
“I want that cock in my mouth,” Loki whispered, kissing and sucking his way back down the muscle of his chest and abdomen, leaving a trail of purple marks.
When he reached the hard length, he licked it from base to tip, savoring how it tasted and felt, then sucked the head into his mouth, his tongue playing with the tip and slit. He found the sensitive spot just under the head and used the tip of his tongue to tease it mercilessly until Bucky was squirming under him.
“Oh, Christ.”
God, he's good--really good.
“You can come anytime, Barnes. Don’t hold back. This one’s for me, and there will be a second very soon.”
When he sucked the whole thing down in one move, Bucky’s hips lifted off the bed and he bit back a startled yell. The suction was so strong and so tight, the tip hit the back of Loki’s throat and stayed there, with Loki holding his breath and only coming up for air about every third or fourth stroke. He grabbed one of Bucky’s hands with his own and fisted it in his hair, encouraging him to push and pull. Within a minute, his mouth filled with the human’s cum and he pulled out just far enough to taste it on his tongue. He swallowed and then kissed Barnes just as deeply as he had the first time. They were both breathing hard, laughing a little, and just generally enjoying the moment until their breathing slowed.
“I knew you wouldn’t disappoint me. You taste as delicious as you smell. How long until you can go again?” Loki asked, climbing on top of Bucky and straddling his hips.
“Whoa, big guy. Jesus, you’re pushy. I know you’re a god and all, but we humans need a few minutes.”
“Even you? I thought you were more than human now."
“Well, yeah, but even I like to just enjoy it for a goddamn minute, at least.”
Loki moved Bucky’s Vibranium hand to his rock-hard cock.
“Rest later. I want to see what you can do with this thing.”
“You mean like crush M-16’s and rip off car doors?” Bucky asked with a wry grin.
Loki laughed, his head thrown back in a way Bucky found incredibly attractive.
“Yes, I have seen that. But, I’ve also seen you pick up a toothpick and pet a kitten, and right now I have something I’m dying for you to stroke.”
He rolled over onto his back, looking up at Bucky expectantly.
“I honestly can’t believe you’d trust me with this, Odinson. What if I accidentally rip your dick off?”
“Then, you’ll be dead and I’ll be in a lot of pain until I heal. Neither of us wants that, Barnes. Besides, we both live for the adrenaline, don’t we?”
Bucky carefully took hold of Loki’s cock and began to stroke it. Apparently, giving blow jobs was a real turn-on for him, and just touching it made him gasp.
“Ah...that’s good, Barnes...very good. A little firmer would be even better.”
“Damn, Odinson, are you always this bossy during sex?”
“I know what I like.” He grinned.
“But, all right. Maybe a little more lube and then I’ll be quiet."
Quiet, he was not. But, the rest of the time, his vocalizations consisted of pleasured moans, grunts, and a few words Bucky didn’t recognize, but was pretty sure were Asgardian swearing. He certainly did seem to be enjoying it. When the metal fingers gripped way more firmly than seemed possible for a human to tolerate, Loki groaned loudly and came all over the hand and himself, fingers curling into the sheets.
Not being able to resist, Bucky sucked a big, purple bruise into Loki’s neck, and the god did not protest. He arched his neck, closed his eyes and seemed to love it, in fact. After a few minutes’ rest, during which Loki magicked the cum off his chest, Bucky started to get up and extended a hand.
“Shower? I’m highly trained in covert underwater activities.”
“Not a chance, Barnes.”
Loki pulled him back down to the bed and pinned him on his back with both hands above his head.
“I told you what I wanted from you, and I don’t mean to let you up until I get it. Unless you’ve changed your mind, that is.”
“God, you really are a demanding son-of-a-bitch. I didn’t think you meant all at once.”
He laughed, broke his hands free, and pulled Loki down by the back of his neck until they were panting into each others’ mouths.
“Make me feel that perfect cock, then.”
Loki grinned and slipped one finger inside Bucky, then two, producing his magic lubricant while stroking his prostate—one of his favorite tricks.
“You can really do that? I thought that was just a rumor. You’re full of magical surpri—oh...fuck...that feels good.”
Loki continued stroking until Bucky was writhing and moaning so beautifully for him that he could not hold back any longer. After another moment of magic prep, he lined up the head of his cock and began to push.
“Wait. Are you sure that’s enough? I’m no expert on magical lube and stretching, but you...aren’t small. I can’t promise I won’t punch you,” Bucky said.
Loki’s answer was to bite down on the human’s neck below the corner of his jaw just as he pushed inside. The combination was enough to make Bucky groan and pull the god into a deep, wanting kiss.
“Mmm...fuck...so good...don’t stop. Ever.”
Loki’s hands on Bucky’s hips were trembling with the effort of going slow until he was all the way in, because he wanted so badly to just fuck Barnes. Once he could go no farther, he stopped and took a breath.
“Good?” He asked. “I want to move now.”
“Odinson. I was promised balls-deep, mind-numbing fucking. I’m good."
That was all Loki needed to hear, and he began to move in earnest, pulling out almost entirely, dragging his cock over Bucky’s prostate as he went, then pushing back in hard. Strong legs wrapped around his back, pulling him in deeper, and every time he hit that magic spot, the loud moans of pleasure made him that much harder.
“Ahh...Barnes...you're so...so tight and so hot.”
He snapped his hips forward, and Bucky’s fingers dug into the sheets, tearing holes through them and into the mattress.
“Oh...fuuuck yeah...”
He hadn’t thought he could come again so soon, but maybe Loki was working some magic there, too; or, he was just that good. He reached down to take hold of his own cock, but Loki grabbed his wrist and twisted his hand away.
“No. That’s mine for now, and you don’t get to touch it.”
Loki’s voice, the possessive tone, the wicked depth of it, made Bucky squirm even more. He wasn’t used to being controlled that way and he liked it. The fact that Loki might actually be able to overpower him made it that much better, and a series of hard thrusts almost made him come without a hand touching him.
The tension was building inside Loki now like a coiled spring, and he was sweating and groaning with the effort of pounding Bucky into the mattress harder than he could ever do with a normal human. He grabbed Bucky’s cock and began to stroke hard, matching his own rhythm. It was dripping pre-cum and Loki loved it.
“Come for me now, Barnes. I want to see it.”
A few more strokes into Loki’s fist and Bucky came hard, splashing ropes of cum everywhere. When he did, he clenched around Loki’s cock and the god was close behind, pulsing into that soft, tight flesh. Loki kept thrusting until he was spent and the body under him was limp, then rolled off onto his back, breathing hard.
“I was so right about you, Barnes. Finest ass on Midgard.”
“Loki. You suppose we could be on a first-name basis now, seeing as how you just fucked me into another dimension?”
Loki wrinkled his nose in obvious distaste.
“Maybe. But, I refuse to call an adult male ‘Bucky’.”
“Fine, Your Fucking Highness. James will do.”
