This mission isn’t high priority, but when Loki reads it on the TVA’s to-do list, he knows he has to go.

He misses Asgard, he misses his family. The comfort and familiarity of home are lost on him during his seemingly endless time at the TVA.

So he ignores Mobius’s suggestion to go with him and travels to the unfamiliar timeline by himself.

He walks down the rainbow bridge in awe. Asgard is as beautiful as he remembers it being. The golden palace, the clear water, the citizens he walks past on his way.

It puts Loki at ease, seeing his home, his people. He’s surprised no one has recognised him as he walks through the busy streets, no one pausing to even look his way.

By the time he reaches the palace is when he decides it’s time to put his powers to good use. He shifts his form and slithers through an open window, cautiously moving down the familiar golden hallways and corridors.

Finally, he reaches his room. He slips into the crack under the door and looks around in surprise. The room is nothing more than a closet, filled with cleaning supplies and miscellaneous items.

He frowns, still disguised, before he slithers out into the hallway again. Maybe this variant of himself is king, and his bedroom is where his father’s once was.

He passes by door after door until he reaches the king’s quarters. He slides under the door again, staring up in utter shock.

It’s Thor’s bedroom. He knows his brother’s tastes like the back of his hand, and the fur blanket covering the bed is more than enough to let him know that the room is Thor’s.

However, what gives him pause is himself. His variant is sitting on the edge of Thor’s bed reading a novel Loki can’t place.

The Loki variant wouldn’t surprise him if he wasn’t completely blue. His red eyes flicker over the pages of the book, completely entranced by whatever it is he’s reading.

It took Loki years upon years to be comfortable with his heritage, and he still refuses to show anyone his true form. He can’t imagine living in his Jötunn body in Asgard.

And yet, his variant pays it no mind. The walls of the king’s room are tall enough for him to stand upright despite his size, and Thor’s bed is just as large, as if built for a Jötunn.

It baffles Loki for a moment before he remembers why he’s here. He needs to take this Loki’s place for a little while before he can find the anomaly in this timeline.

He slithers up to the bed and bites his variant’s ankle, pumping a magic toxin into his veins, putting him to sleep.

Finally, Loki returns to his normal form, concealing his variant’s unconscious body with another spell. Hopefully both will last until he completes the mission.

A knock at the bedroom door startles him out of his thoughts, and he shapeshifts to look identical to his variant. He feels odd, unlike himself as he stares down at his blue hands, but he pushes past his discomfort to greet whoever is outside.

The door swings open unceremoniously, and he can tell it’s Thor before he even sees his brother’s face. He’s much shorter than Loki in this timeline, craning his head up to meet his eyes.

“Elskan, my darling, you still aren’t dressed?” Thor leans in to press a kiss to Loki’s bare chest.

Loki stares at his brother in silence for a moment, utterly baffled. He hadn’t even considered the possibility that he and Thor wouldn’t be brothers in another timeline. The term of endearment nearly makes him jump out of his skin.

“Ah, the dinner can wait an hour or two.” He chuckles, resting his hands on Loki’s hips. “Were you waiting for me, darling?”

The touch makes Loki melt. He should pull away, he’s tempted to, but he can’t afford to blow his cover before he completes the mission. And, selfishly, he wants to see where this leads.

“I missed you.” Loki mutters under his breath, wrapping his arms around Thor’s shoulders.

Thor outright grins at that, his ocean blue eyes near sparkling. Thor has always been attractive, his smile especially. Golden blond hair and the spattering of freckles covering tan skin, barely visible outside of direct sunlight.

“I bed you just this morning.” Thor replies, guiding Loki to take a seat. “But I shouldn’t deny you of what you want when I want the very same thing.”

Loki smiles sheepishly. He’s been bed before, near countless times, but the thought of having his own brother inside of him is unfamiliar and frightening.

“Do you desire my mouth first, darling?” He mutters as he kisses along Loki’s shoulder, his lips pressed to blue skin. “Your cunt fluttering around my tongue while I stroke you? Do you desire that, my love?”

Knees trembling at the sheer thought of it, Loki nods. Being a shapeshifter has meant, for every other intimate relationship he’s had, that he must bend to the whim of whoever beds him.

The sheer concept of Thor on his knees, the mental picture of his tongue moving from Loki’s puffy cunt all the way up to the tip of his shaft makes him whine.

“Please.” He begs, desperate enough to do so. “Please, darling, I need you.”

It takes little effort for Loki to undress, his royal Jötunn attire leaving him mostly bare already. Still, when his cock meets the cool air of the bedroom, he can’t help but sigh in relief.

That is, before Thor’s mouth is on him.

He lavishes the tip of Loki’s cock in affection, pulling back his foreskin to tease the sensitive glans with his tongue. He grins as he keeps eye contact with Loki as he takes more of his cock into his mouth.

The tight, wet heat of Thor’s throat is near suffocating. Loki’s cock twitches, his veins pulsing as it sinks inside inch by inch. Thor struggles to swallow his own saliva as he bobs his head up and down, the wet noises making them both squirm.

“Oh fuck…” Loki curses, watching the blond choke on his cock. “So good for me, baby. You’re such a good boy.”

Thor’s eyes begin to water, struggling not to gag as he takes the full length of Loki’s cock down his throat. He nuzzles into the coarse ebony hair on Loki’s groin, breathing deeply through his nose.

“You wanted to smell my cock that badly, hm?” Loki teases, breathless as he tries to adjust to the feeling. “Didn’t you say you would pleasure my cunt as well?”

Gagging, Thor pulls off of Loki’s cock, spluttering for a moment before he dives face first into Loki’s cunt. He laps at Loki’s puffy, purple clit and that’s all it takes.

The overwhelming ecstasy of his orgasm leaves Loki trembling, dazed as he paints Thor’s face in rope after rope of cum. He grins once he looks down again, admiring Thor’s shy smile in response.

“We really shouldn’t waste any of it, darling.” Thor comments idly, wiping the thick, creamy spend from his face. “I’d hate for this to take longer than it already has.”

All Loki can do is watch in bewilderment as Thor undresses, spreading his legs to reveal his own cunt. The blond hair covering his sex is matted with wetness, his pink, curled labia glistening with it.

The moment Loki’s cock throbs at the sight, already starting to harden again, Thor spreads his folds apart with his fingers. The soft, gummy insides look beyond tantalising, making Loki drool at the thought of being inside of them.

Until, finally, Thor’s cum covered fingers push into his puffy cunt. The moment Loki can think again he’s stammering, stuck between wanting to watch it happen and wanting Thor to stop.

“I want this baby.” The blond whispers, pushing Loki’s cum deeper inside of himself.

Loki squirms, his cock throbbing as it returns to full hardness. Thor watches hungrily as it twitches against Loki’s thigh, moving to straddle the Jötunn’s waist.

“Let me do all of the work. Rest, darling.” He whispers into Loki’s ear, grinding his cunt up against Loki’s length.

When the purple, swollen tip catches on Thor’s dripping hole, Loki can’t find the strength to deny him, biting his lip as the variant of his brother sits on his cock.

It’s all so disgusting, arousing, even, when Thor’s soft, gummy insides coil around Loki’s shaft. It’s impossibly wet, lewd noises filling the room even as Thor does nothing but attempt to take it all inside of him.

The tightness makes Loki’s brain melt, laying back against the bed limply as he bottoms out inside the blond. Thor groans as he starts to move, riding his lover with practiced patience, slowly gaining momentum as he moves.

Weakly, Loki grabs Thor’s hips, coaxing him into bouncing faster, loving the way their bodies slap together with every thrust. He tips his head back, groaning as he becomes determined to get Thor pregnant.

As Loki starts to thrust up into Thor’s cunt, he can’t help but lose himself in the pleasure, speeding up his movements until Thor screams.

“Yes! Yes! Fill me up! Give it to me, please!” He begs, his thighs trembling as he gives in to the pleasure.

Thor shudders as he squirts, his cunt tightening and pulsing around his lover’s cock, milking it for all its worth. He collapses onto Loki’s chest, too spent to sit upright any longer, trembling.

Loki thrusts up into Thor’s sensitive cunt, working him through his orgasm as he chases his own. He holds onto Thor’s hips tightly, keeping him in place as he curses.

“Oh, yes… I’m coming!” He warns, thrusting in as deep as he can reach.

Finally, the thick, creamy ropes of Loki’s spend spill into the depths of Thor’s cunt. The size difference between them is emphasised as Thor’s cunt quickly overflows, his belly distending slightly as he moans.

“Yes… oh, gods, I’m so full.” Thor grins, sliding his hands down his own belly, humming as he feels Loki soften inside of him.

Gently, Loki pulls out, wrapping his arms around his brother to keep him close. In the post nut clarity, Loki realises that he still has to complete his mission, and that he won’t be able to return to this timeline again.

He presses a soft kiss to Thor’s forehead, deciding that the mission can wait a little longer.
