Chapter Text
Clever as Loki is, he fails to notice that the path Thor chooses to take as he marches his brother through the castle is one that is isolated and purposeless. Their journey is meant to be underway soon, and Thor spoke as if he were on his way to prepare, but this path goes nowhere near any of the places where they ought to be going. The corridor is permanently cast in shadow, narrow and peripheral, and rarely frequented by anyone. It's one of many similar pathways that Loki himself preferred to travel by in his misspent youth, finding the seclusion and shadows comforting. Perhaps that is part of why he fails to note that there is no reason for them to be here; that the Thor he knew would never take such a dark route when broad and brightly lit corridors were available.
But the Thor he knew is gone, as much as the young and blameless Loki is gone. There's a darkness over Thor right now, a black cloud smeared onto him that Loki is equal parts proud of and frightened to see, because he is the one who managed to work Thor into such an unforgiving mood. Getting under Thor's skin is far too easy, an old game, really, but this time... this time Loki actually worries. Things are so different now. New York was not a game. Some days he even regrets it. Some days he worries that it will be the first thing Thor never forgives him for.
He flinches when Thor yanks his chains, dragging him along at a pace that it unrelenting, always a half-step faster than Loki can manage to keep up with. He's nearly tripping over himself, his chains pulled tight on his wrists and throat, but every time he snarls in protest, Thor wrenches them even further, so that Loki has to try to keep the brutal pace in order to avoid being strangled.
So focused he is on the tight grip Thor has on his leash, literally, it's not entirely surprising that Loki fails to notice how far astray Thor has led him. Not until Thor abruptly stops, one hand still clutching Loki's chains in a vice grip, the other hand closing around Loki's throat without warning and shoving him bodily against the wall.
All at once, Loki realizes what Thor has done - taken him aside, somewhere entirely secluded - and that he is about to reap the wrath he's been seeding in Thor for so long. Loki manages a harsh gasp before Thor's fingers dig into his neck in a hard, decisive action, effectively closing his airway.
"I don't want to hear anything from your needling tongue," Thor snarls, his voice as low and as dark as the shadows that cloak them in the light-starved passage. The pressure on Loki's throat releases just as quickly as it had struck, but for a long second afterward, the dishonored prince cannot draw a breath. In that moment of time, Thor grabs hold of Loki's hair, yanking viciously until Loki is turned to face the wall. Thor shoves him again, Loki's head momentarily cracking against the stone and making him see splotty red visions that ache in the veins of his eyes.
"Thor," Loki growls, but the sound comes out entirely too breathy and almost pleading even to his own ears.
"You've been disrespectful for far too long. You are my prisoner," Thor says precisely, a feral emphasis on the possessive word that makes Loki shudder. The warrior has him crowded him against the wall, every inch of his lean frame covered by Thor's broad body, as if to physically remind him of just how much smaller and weaker he is compared to Thor's raw strength. That he is literally at his master's mercy.
The last thought makes Loki draw an audible breath, and Thor seems to take it as acknowledgment, as the submissive gesture that it ultimately is.
"While you're in my care, you will behave," Thor says, his voice in Loki's ear. The trickster bucks, trying to snap his head back into Thor's, to break the hold, but he misses and suddenly there's a hand planted between Loki's shoulders, crushing his chest and cheek flat against the wall.
"Fuck off," Loki drawls, and then the hand that isn't pinning him to the wall comes up, large, roughened fingers hooking around his bottom jaw and into his mouth. He bites down hard, locking his jaw, but it makes little difference in loosing Thor's grip and leaves him panting through his nose like a wild animal.
"I should have left you in your cage," Thor says, speaking directly into Loki's ear, making him shudder again. "But I need you on this journey, Loki. It makes little difference to me whether you come along by choice, or if I must drag you by your chains across the Nine Realms. But I will have you beside me, where you belong."
His fingers tighten as he speaks, digging further into Loki's mouth. It does not escape him how Loki's eyes shut for a second, nor does he conjure any excuse for Loki's tongue against his skin, the soft, wet noise of a mouth briefly suckling on his punishing fingers. Loki tries to go still immediately afterward, but there is no disguising the quick, hot breaths blowing across Thor's knuckles.
"Is that pleasing to you, brother?" Thor murmurs, nuzzling ever so lightly against Loki's neck as he speaks, able to feel the line of tension trembling through Loki's body. "The idea of being forced before every land in the Nine, chained and humiliated?"
Loki bites down harder and shakes his head 'no' in small, stiff movements.
"Why don't I believe you?" Thor asks, his tone light and mocking. He lowers the hand that was pressing Loki against the wall, drawing it down Loki's side, earning a breathy little shiver. "Because, after all, if you were telling the truth..." he slides his hand over Loki's hip, to his front, and cups the erection he knows is there. Loki reacts immediately, his body twisting uselessly, only serving to thrust himself against Thor's hand. The warrior crowds him even more, his own hips pressing against Loki's backside, seeking friction. "...Then you wouldn't be so hard for me right now. So desperate to be taken."
Thor shouldn't know. Couldn't possibly know.
The words draw an unexpected, broken moan that Loki immediately tries to choke back, gagging on the thick and unforgiving fingers pressed into his mouth.
The thunderer narrows his eyes at Loki, as if finally seeing him for the first time.
"So it is true, then," he says, his voice a rumble against Loki's back. He loosens the grip on Loki's jaw, withdrawing his fingers just slightly and then pushing them in again, and again, fucking Loki's mouth slowly. To his surprise and pleasure, Loki doesn't bite down again, but opens his mouth instead and curls his slick, sinful tongue against Thor's fingers. Within an instant, Thor is gently thrusting into Loki's hot and slick, welcoming mouth, and Loki is nearly beside himself trying to bob his head along with the rhythmic motions. His cheeks hollow out as he sucks. His tongue flickers against Thor's fingertips, trying his best to display all of his talents at once, but the movements are rushed, truly eager.
Thor hisses between his clenched teeth, rutting against Loki's backside for a few harsh thrusts while Loki suckles on his fingers, every slick movement translating directly to his cock.
"I had always heard the rumors that you were loose, little brother," Thor murmurs, almost reverent. "If I had known the truth about you, I would have given you what you wanted ages ago. You never would have been permitted to leave my bed side. That would please you, wouldn't it?"
Loki makes a needy, keening noise in his throat, and Thor can't tolerate waiting any longer. He withdraws his hand, pulling spit-slicked fingers from Loki's hungry mouth with an obscene, wet, popping noise and an involuntary whimper.
His hand easily slips past the tight waist of Loki's trousers, wet fingers quickly finding that little puckered entrance and rubbing hard against it. One finger easily breeches him, and Loki cries out softly as Thor works the finger inside of him, setting his nerve endings alight.
"How many men have you allowed to use you like the proper whore you are?" Thor questions.
Loki shakes his head violently in response, presses his forehead against the wall as he pants openly. His body moves against his own wishes, involuntarily pressing back with every forward movement of Thor's hand.
"You don't even remember the number of men you've had inside you?"
Loki shakes his head again, and finally manages to speak a second later to clarify his meaning, choking out, "Only you."
Thor stills as the realization washes over him. That all of Loki's little noises and sluttish movements are his alone, and the less popular rumor, that the trickster has remained untouched all these years, is the truth. It makes a rush of pride and lust tear through him, and he can't help but press his hardening cock harder into the cleft of Loki's beautiful ass.
"You haven't had me inside you yet," Thor growls, a warning and a potential offer that makes Loki's head swim.
"Please, please," he pants, and cries out in equal parts despair and rage when Thor's fingers leave him so soon.
But he isn't to be disappointed.
Thor twists an arm around Loki's chest, his hand grabbing Loki hard around the chin, forcing him to lift his head up at a painful, glorious angle.
"Tell me what you want."
"F-fuck," Loki pants out harshly. "You. Inside me. Fuck me."
"Suck," Thor commands, and Loki obeys, wetting Thor's fingers quickly and thoroughly while with his free hand, Thor pulls Loki's trousers down just enough to expose him.
Thor presses his fingers into Loki once again, this time finding the friction just a bit easier. He works him open at length, two and then three fingers slipping in, making Loki suck on his fingers again and again until he's almost obscenely wet with his own saliva.
Finally, Thor withdraws just long enough to open his own trousers, his erection flushed dark and slick with a trail of precum. He strokes himself, spreading the slippery fluid from tip to root, and then grasps Loki's hips and pushes in slowly, slowly. He takes his time, working Loki open again an inch at a time, until the trickster is whimpering with want.
When he's fully seated, Thor stills, pressing himself against Loki's back. For a long moment he stays like this, enjoying the clench of Loki's inner muscles, grinding against the trickster until Loki is breathless and begging for him to finally move. Only then Thor obliges, pulling halfway out and then slamming in, again and again, until each hard thrust is punctuated by a helpless moan torn from Loki's throat.
He sets a fast pace, riding into Loki and seeking his own pleasure. Entirely by accident, Thor discovers a new angle that makes Loki gasp and cry out. He stutters his thrusts for a second, taken back by the revelation, and then works to replicate this reaction. A delightful, keening noise is his reward with each inward thrust, his cock mercilessly hitting against Loki's prostate until the they're both panting. The pleasure is unbearable, building, but Thor still notices the clink of chains when Loki tries to move his hands.
"No," Thor snarls, grabbing the chains that connect to Loki's wrists together and yanking up, forcing Loki's hands away from himself. "You'll come from this alone, without touching yourself, or not at all," he pants against Loki's neck, and bites hard into the pale skin as he continues his assault.
Loki makes a low noise of protest, but pushes his hips back against Thor, setting his own counterpoint to Thor's movements.
"That's it," Thor growls, shifting to match his thrusts in time with Loki's movements. "Fuck yourself on me, love." He stills for a moment, forcing Loki to move, to take all the initiative and set his own pace, to fuck himself back on Thor's thick length and show just how much he craves it. Then Thor starts again, unable to hold off, driving into Loki ruthlessly until the trickster is all but screaming, his throat already hoarse. Thor stops that quickly, hooking his fingers into Loki's mouth again and mangling the sound. All at once, the sensation becomes too much and Loki clenches around him as he comes, shuddering hard and sobbing. But Thor doesn't stop, fucking him through it, forcing out a hard orgasm, enjoying the way the over-stimulation makes Loki clench around him. When Loki's moans turn almost painful, Thor takes a small mercy, easing off so that he can make slow, deep thrusts into Loki over and over again until he feels wet drops of tears against his knuckles.
"Should I come inside you?" Thor asks breathlessly, his hips ever working against Loki, as if he could keep fucking him for an eternity, long after Loki had been driven mad from his forced pleasure.
Chained and gagged with Thor's fingers in his mouth, Loki can't speak, can only make little broken, sluttish cries that go straight to Thor's balls. His hips jerk forward involuntarily, the instinct to breed coming forth as his seed does, pushing as far as he can into that tight, clenching passage. Loki moans aloud, mindlessly sucking hard on Thor's fingers while at the same time he can feel Thor's pulse inside him, his hot seed spilling into him. Filling him up on both ends. Fuck.
"So good, Loki," Thor purrs, patronizing. He continues to rock his hips leisurely, until his softened cock falls free from the newly stretched hole. Finally, Thor pulls his fingers free from Loki's mouth, lets go of him completely while he fixes his own trousers.
Loki sighs softly and rests his forehead against the wall, sore, sweaty, trembling; completely fucked out, sloppy and sated and beautiful. He startles slightly when Thor's fingers abruptly push into him again; fails to stop a small moan when those fingers press hard against his prostate; blushes as Thor scissors him apart with a slick noise that's entirely obscene.
"You're perfect like this," Thor says. "Open and wet with my come. I ought to keep you like this forever. I think I will." There's a rustle of clothing, and then Thor pulls his fingers out, replacing them with the tip of something smooth and blunt. He pushes it into Loki without pretense, the object widening quickly, until Loki almost cries out with alarm, but at its widest point it suddenly narrows again, and then the base is seated against his ass, preventing it from slipping in any further, plugging him up. The toy is thick, and short, and perfect for keeping all of Thor's release trapped inside of him, teasing Loki at the same time and providing absolutely no relief.
Thor lets go, leaning back to admire his handiwork, the sight of Loki's pale backside squirming as he tries to adjust to the intrusion. "Thor," Loki rasps, unsure of what he even intends to say.
"Don't act so shocked," Thor says, slapping Loki's pale ass with a resounding smack that makes him jolt with both pain and pleasure. "You've doubtless had this inside yourself before, a thousand times over. I found it in your chambers, after all."
Loki doesn't know how to respond to that, so he stays silent. He wants to ask Thor why. Or more importantly, how he can be so calm now, his hands steady as he patiently tugs Loki's trousers back up over his hips and fastens his clothing back into place. As if nothing has happened at all. But when Thor turns Loki around to face him, he slips a hand between Loki's thighs, cupping him roughly and pressing the plug into him.
"I should have done this long ago," Thor says, pressing a sloppy kiss against Loki's jaw. "This will keep you open for me, aching. Ready to be taken at any time. It suits you, I think. The only thing I can't decide is... if I should fuck you for spite, or for reward."
Loki's chained hands shoot up, grasping Thor's face with harsh fingers, pulling him close so that he can devour and bruise those lips. Thor chuckles darkly against the kiss and opens up to Loki's eager, filthy tongue. Short seconds later he ends it, grabbing Loki by the throat and pushing him off.
Loki has a grin spread across his mouth. Thor presses a thumb against Loki's bottom lip and tries to rub that smirk away, although he can't help but smile as he does so. When Loki closes his eyes blissfully and flicks his tongue against Thor's skin, the smile turns into an absolute grin.
"Good boy."
