Chapter Text
It starts off small, barely noticeable. Thor is sitting at a feast in the banquet hall and he shifts in his seat to turn and comment on one of Volstagg's jokes. That's when he feels just the lightest brush against his cock, barely there. Perhaps it was just the pull of fabric as he moved. Perhaps he imagined the whole thing.
He feels it again in the tavern with his friends that evening, but he doesn't think much of it. With that much drink flowing it's hard to be certain of anything. It's not until the next morning that he makes the connection.
Thor dresses and gets ready for his princely duties, just like any other day. But when he reaches for Mjolnir, something is different. He calls the hammer to him and the moment his hand firmly grips the handle he feels that sensation again, but stronger this time. It should be impossible, but every touch upon the hammer feels like he's touching himself and he shudders at the sensation. That's when he remembers that in both instances the night before, he'd had Mjolnir with him. She sat resting at his feet at the feast and secured to his belt as they drank and danced the tavern.
Every day it only gets worse, the hammer becoming more and more sensitive. Each brush of his hand against the handle feels like he's stroking his own cock, a delicious jolt of pleasure coursing through him. It gets to the point where he cannot even keep the hammer strapped to his belt because when it brushes against his breeches as he walks, he's painfully hard within minutes.
On the third day he finally gives in. Most evenings, Thor is out and about with his friends, gallivanting around the town. But tonight he begs off, tells them he's feeling ill. The door to his chambers is barely shut behind him before he's calling Mjolnir to him and taking the shaft in hand, stroking it like he's been dying to for days.
"Ohh," he shudders, working his hand up and down the hammer. The sensation is intense, as if he's pleasuring himself but somehow… more. Reluctantly he puts the hammer down on his bed. He has already waited so long, just a few moments longer and he can have what he so desperately needs. He's far too worked up to bother with his shirt, but he yanks off his boots and breeches until his lower half is completely bare. Shivering with anticipation, he lays down on the bed. Then he takes his cock in one hand and the shaft of the hammer in the other and strokes. A choked out moan escapes his lips and though he has held Mjolnir a thousand times, the ridges of the hammer's shaft on his calloused hand has never felt so good.
As a warrior, Thor has excellent coordination, but never in a million years did he imagine he'd ever use those skills in this way. He tries different things, one hand focusing on the shaft of the hammer, the other running a thumb over the head of his cock. The hand on his cock stroking up and down furiously while the other hand is gripping and twisting just right.
Beads of sweat start to form on his body, making his shirt stick to his skin. His breaths are coming out shorter, fisting his cock and hammer desperately as his hips work up and down seemingly by their own accord. He is close now, so close.
This is only the beginning, he thinks, because there are so many other things he could do. Thor lets his imagination run wild which only heightens his pleasure, making him moan out loud, making his whole body ache for release.
He's not flexible enough to suck his own cock, but now? He could take the hammer into his mouth, licking it and sucking it so good because he knows just the way he likes it. Or he could stretch his hole open, slide down on the shaft, and know what it feels like to fill and be filled at the same time. He could have it, he could have it all-
"Yes," Thor gasps as the pleasure ratchets up in intensity and he feels his orgasm finally hit him. His whole body goes taut, making his toes curl and his back arch as shoots load after load of hot come all over his bedsheets. When it's over, he lays on the filthy sheets, flushed and panting and utterly sated.
But how is this possible? What does it mean? He has always felt a bond between himself and the hammer, as if it is an extension of his body. He wonders if perhaps they are meant to be this connected. Is it a phase that hammer and master must go through?
Father would know, Thor thinks, but he is far too embarrassed by the whole thing to ask him.
From then on, he leaves Mjolnir in his room. People start to ask him why he is not carrying it, and he tells them that a man should not rely on only one weapon, that it's important he hone his other skills as well lest he and Mjolnir be separated during a battle. Most of the others just smile and nod, but Loki always looks at him like he knows Thor is hiding something.
Some days later, Thor is walking back to his rooms after an invigorating sparring session when he feels it. The unmistakable slide of a hot, wet mouth over the head of his cock. He stops dead in his tracks and it takes everything in his power not to cry out, not to beg and plead for more. He won't make it to his chambers, not like this. He has to do something soon or people will see. They'll all see the Crown Prince reduced to a wanton slut, moaning and coming all over himself. Thor looks around to find somewhere, anywhere where he can hide because the mouth is working steadily up and down, and showing no sign of letting up.
Biting his lip so hard that he draws blood, Thor ducks into a corridor and hopes fervently that no one is there. Thankfully, luck is on his side today because it leads into a small sitting area which is currently deserted except for a table, some armchairs, and a large tapestry against the far wall. On shaking legs, he manages to take a few more steps forward before falling to his knees, sweat dripping down his brow as the wet heat continues to envelop him. He puts his fist in his mouth and bites down hard to muffle his moans.
Just a little bit further, he tells himself, struggling not to let the pleasure consume him completely.
He crawls the rest of the way until he's finally under the table. From there on his knees, he's able to pull the tapestry back from the wall, just enough for him to slide underneath it and press himself up against the hard stone. He knows that his feet are poking out and the outline of his body can still be seen. It's not the best hiding place, but it will have to do.
Thor yanks his breeches down just enough to free his cock and then presses his face against the wall, letting the stone muffle his cries as he is engulfed over and over again. At last, he can just give in and let himself have this. He grunts and moans, working his hips in the air in his passion. The pleasure starts to build in the base of his spine but before he's pushed over the edge that mouth - that hungry, eager mouth - pulls away.
"No, please," Thor begs, rocking his hips forward in frustration.
"Please," he moans again, and then he feels the flicker of a clever tongue against the head of his cock.
"Oh yes, please," he pants and the tongue licks a long stripe up the length of his dick, from base to tip. The mouth continues to tease him, licking his shaft, sucking on his balls and pressing wet, open-mouthed kisses to the head of his cock. And it's so good but not it's not enough, never enough.
He is shameless now, overcome with desire. Anyone could hear him, anyone could come in and find his hiding place. He should be mortified - and he is - but it also makes him more and more aroused. He braces his hands against the stone wall, clawing at it desperately.
"Oh please let me come, let me come," he chants, not knowing how or why this is happening, but needing it all the same.
Just when he thinks he will die from the frustration, that hot mouth is moving and swallowing him down. Thor screams as climaxes, hoping that the stone wall absorbed the sound but too far gone to actually care. He pants heavily as he comes down from the last shudders of his orgasm. Thor rests there for several minutes, waiting for his heart rate to get under control again. He takes a deep breath and turns around. Crouching down even lower, he lifts up part of the tapestry to peek underneath.
From what he can gather, the coast is still clear. He smells like sex and his breeches are a complete mess, but if he hurries he should be able to make it back to his rooms without being seen. Thor takes another deep breath, crawls out from under the table, and stands upon wobbly legs. Hastily, he re-fastens his breeches and sets out into a run. The only people he passes on the way are two chambermaids who stare at him like he's crazy, but he takes it in stride. It could be worse. He could have been seen by Frigga.
Thor throws open his chamber doors and runs into the bedroom but no one is there. The hammer is still there on the rug across from his bed. Since no one else can lift it, he's never bothered with hiding it. He inspects the handle but it appears to be completely dry (he doesn't dare touch it, he is far too sensitive for that yet). In fact, nothing looks out of place at all. But someone was here, he knows it. He can't help but remember the look on Loki's face when Thor had made excuses about why he did not want to use Mjolnir.
He has the sinking suspicion that someone is playing a trick on him and he's almost certain he knows exactly who it is.
***
When he finally finds Loki, it's in a secluded corner in the main library.
"Looking for me?" Loki asks, not even bothering to look up from his book.
Thor snatches the book out of his hands and tosses it aside.
"I was reading that, you brute!" Loki says, but Thor pays him no mind.
"What have you done with Mjolnir?" he demands.
"What do you mean, Thor?" Loki says, sounding annoyed. "I do not have your precious hammer, you know that I cannot lift it," and there's a hint of bitterness in his tone.
Thor growls in frustration. "You have done something to it, trickster. I know it was you!"
Loki rolls his eyes. "If Mjolnir is not with you, it must be due to your own carelessness. What happens to your belongings is none of my concern."
"It's not-" Thor starts to shout when he remembers that they're in a library, so he reduces his voice to an angry whisper. "It's not that Mjolnir is missing. I know exactly where she is, safely in my chambers."
"Well, there you go," Loki says, "problem solved."
Thor clenches his fists. "Why must you taunt me? The hammer is not missing, it's just that when I touch it I… I cannot touch it without…" Thor stammers, and he realizes that he didn't really think this whole confrontation through. It's one thing to feel his hand upon Mjolnir's handle as if he were stroking his own cock. Or to feel that hot, wet mouth of a phantom lover on him. But it's quite another thing to share that information with someone else, even the person he suspects is the cause of it all.
"Well, what?" Loki says. "Spit it out, Thor. I have other things I'd much rather be doing, like reading that rare book you threw on the floor."
Thor squirms and opens his mouth but the words refuse to come out. Loki glares at him, raising an eyebrow pointedly.
"You look like a fish with your mouth gaping open. Either tell me what troubles you or shut your mouth and leave me be."
Thor feels the flush rise on his cheeks. "I… when I touch Mjolnir's handle, it… it feels like I'm touching myself!" he manages to blurt out.
Loki looks confused. "What do you mean, Thor?"
Thor glances around, making sure no one is listening in. "It feels like I'm touching my… my manhood," and he feels his face flush yet again.
"That is absurd," Loki says, disbelieving.
"It is truth! And I believe you are the culprit."
Loki looks absolutely affronted, and if he's lying his deception is flawless. "Why would I do such a thing? And even if I wanted to, you have seen me weave magic, brother. When have you ever known me to do an enchantment such as this?"
"You know I am not well-versed in magic, Loki," Thor grumbles. "And besides, you are clever, you can learn anything you put your mind to."
Loki gives a long-suffering sigh and begins attempting to explain the mechanics and complexities involved in enchanting objects. But as Loki speaks, Thor finds that he is no longer listening because he can't take his eyes off of Loki's mouth.
Was it you? he wonders. He imagines how obscene it would be to see Loki's pink lips wrapped around Mjolnir's shaft, how they would stretch. And even better, how would his lips would look wrapped around Thor's cock? He can feel himself start to harden a little at the thought.
Thor can't pretend that he's never looked at Loki in that way. He would be blind if he didn't notice what a gorgeous man his brother has grown to be. But it is wrong. They are brothers and it can never be. But in light of recent events, he can't help but wonder, can't help but want.
"Thor!" Loki says, kicking Thor in the shin.
"Ow!"
"Were you even listening to a word I said?"
"I..."
"No, of course not," Loki says with a roll of his eyes. "I try to help you and you don't listen."
"Loki-"
"As I was saying, I am not well-versed in this area of magic, but someone such as…hmm, maybe Amora. Something like this is certainly within her power."
"Hm," Thor says.
"Didn't she attempt to win your favor fairly recently, brother? She was quite heartbroken when you rejected her. Perhaps she seeks revenge against you."
"It is… plausible. I will speak to her."
Loki nods. "And if she causes you more trouble, I would be happy to… speak to her," he says, conjuring a flame in his hand.
"That will hardly be necessary," Thor says, and he can't help but chuckle, "but I thank you for your concern."
He turns to leave, mulling over his thoughts as he makes his way back to his chambers. It would not be unlike Loki to want to humiliate Thor, but now Thor is uncertain. Loki seemed so genuinely concerned that it makes Thor wonder if perhaps this is not his doing.
His brother is wily and clever, and they do not call him trickster for nothing. But if he is lying, Thor has no evidence. For now, all he can do is watch and wait.
***
Thor fully intends to question Amora about his suspicions, but there is no time. Because a couple of days after his conversation with Loki, it happens again.
He is leaving the training yard with Sif, laughing and talking with her when he feels tight heat, oh so tight, sliding down his cock. His phantom lover has returned and Thor bites his lip hard because he knows what this sensation is. He's had men before and he knows what it feels like to stretch another man's hole open and sink his cock inside.
"Thor, what's wrong?" Sif asks.
"It's…uh, nothing," he manages to choke out. "Just my stomach. I think perhaps my breakfast did not agree with me."
She looks at him in concern. "You should go to the healing chambers-"
"No! I mean, it's no cause for worry, I will just lie down for awhile, I'm sure I will be fine."
"Well, if you insist-" she starts, but Thor is already halfway down the corridor and doesn't stay to hear what else she has to say.
***
Thor dashes into his chambers this time Loki is there and the sight of him takes Thor's breath away. He is on the floor, completely naked, cock flushed and hard, and Mjolnir's shaft buried deep inside him.
"Ah, hello Thor," Loki smirks. "So nice of you to join us." And with that he smiles wickedly as he slides almost all the way up the shaft and then forcefully shoves himself back down.
Thor can't help the low moan that comes out of his mouth. "But why are you doing this?" he pants. "If you desire me, then why lie? Why trick me?"
"Because you are…ah… too noble to take what you want." Loki grips his own cock, slowly working it in tandem with hips as he rides Mjolnir.
"If I had come to you, I if…mm…if I told you that I wanted this. Would you have said yes?"
"Loki, I…"
"You would not," he says with a vicious slide that makes Thor's knees weak. "What you needed was a push and I, oh Thor, how wonderfully I have pushed you."
Loki continues to slowly work his hips up and down and Thor yanks his own clothes off as he shudders and shakes through the feeling. When Thor is naked before him, Loki licks his lips.
"Come here, Thor," Loki says, his voice hoarse with want. Thor obeys. He is far beyond thinking about what is right and proper. His only thoughts are of Loki, of having him any way he can get him.
"Loki," Thor moans when Loki stills his hips, seating himself firmly on the hammer.
"Don't worry, brother," Loki gasps, "I am not through with you yet."
"Please, tell me, what would you have me do?"
Loki moans. "Let me take you into my mouth, Thor. I want to feel you inside me at both ends."
Thor groans and grips the base of his cock hard to keep himself from coming.
"That's it," Loki says, "we can't have you spilling too soon."
Loki raises a finger, beckoning Thor closer. "Come on," he says, "use me. Fill me up."
Thor crosses the distance between them and then grips a hand firmly in Loki's hair, forcing his brother to look up at him. Loki's cheeks are flushed, his pupils blown almost to black. His lips are reddened from where he's been biting them to hold back his moans and Thor wants to be inside him more than he's ever wanted anything.
Loki nods and Thor pulls Loki's head forward and pushes it down on his hard cock.
"Yes," Thor moans, and it's so good, even better to feel Loki's mouth on his actual cock and not just the hammer. Thor does not let go of Loki's hair but he loosens his grip, lets Loki work his mouth up and down his length. The feeling is exquisite, but Loki has other plans for him. Slowly but surely, Loki starts to move his hips, working his ass and riding the hammer again.
Thor shouts and Loki moans against the cock in his mouth, the vibration sending sparks of pleasure down Thor's spine. It's incredible, unlike anything Thor has ever felt before. It's on the verge of being too much, but everything is tight and wet and perfect.
"So deep inside you," Thor moans, giving himself over to it, letting everything go.
The room is a cacophony of noises, their grunts and groans, the slick sound of the hammer's shaft plunging into Loki's tight hole, and the wet slide of Thor's cock in Loki's mouth. Thor is incoherent now, his vocabulary reduced to "Loki" and "brother" and "please". His legs shake and he can barely stand. Without Loki's strong grip on his ass he would have fallen over long ago.
Thor loses control and feels his hips thrusting with pure abandon, shoving his cock down Loki's throat and Loki just takes and takes and takes. He can hear the sound of Loki's hand furiously working his own cock and then Loki is coming hard. His ass clenches around the hammer's shaft as he spills, he moans around Thor's cock, and Thor can't think, can't do anything but shake as he's hit with the most powerful orgasm he's ever experienced.
***
Thor isn't sure what happened afterwards or who cleaned up who, but when he wakes again he is naked in his bed, with Loki's warm body pressed against his. Mjolnir is across the room looking as pristine as ever, all evidence of their earlier activities gone. Thor can't help but feel a little disappointed. He knows he shouldn't enjoy the thought of his hammer being so defiled, but Loki brings out a darker side of him, one that revels in it. And this is just the beginning. There are so many things left for them to explore.
He rolls Loki over at looks down at him. Loki looks exhausted, but also quite pleased with himself. Thor kisses Loki and runs his fingers through his dark hair.
"You are incorrigible, brother."
"I think I'll choose to take that as a compliment," Loki says.
Thor smiles and kisses him again. "I intended it as such. But I must ask, will you take the enchantment off of the hammer now?"
Loki sighs. "Yes, if you insist. You're such a spoilsport, Thor."
Thor gives him a suggestive look. "I asked that you remove the enchantment now. But I didn't say forever."
"Oh Thor," Loki says with a wicked grin, "we're going to have so much fun together.
