Although it was a great shock to his identity, a part of Loki was actually relieved to know that he was adopted. Now he had no guilt or taboo standing in the way of his heart's deepest desire. As far back as he could remember, he had lusted after his elder brother, the mighty Thor. It was no secret that Loki was more interested in men than he was in ladies; practically everyone in Asgard knew that. Homosexuality was accepted in Asgard, but incest was not. So for long, torturous years Loki had suppressed his desires, pushed his lustful thoughts from his mind, and averted his eyes from Thor's divinely chiseled figure.
But now he knew that they were not blood-related after all. Excitement surged through Loki at the concept of his fantasies coming to life. But how could he bring them about? The thought of bluntly telling Thor how he felt made the trickster god blush. No, that wasn't the way to go about it. He would have to be more sneaky, more low-key about it, and if anyone knew how to do that, it was Loki. He suspected that Thor was a bit bi-curious despite his facade of manly ruggedness. Perhaps there was a way for Loki to seduce his elder brother.
Loki still thought of Thor as his brother even though he technically wasn't. They had grown up together, after all, and had been companions through thick and thin. In spite of the shame he had experienced before, Loki now felt a certain thrill at the concept of incest. There was still a forbidden, taboo edge to his desire for his adoptive brother that made it all the more exciting.
The trickster found his opportunity one evening after a great feast in Odin's dining hall. Thor had been his usual bawdy self, downing ale and flirting with every young female in sight. But he hadn't sneaked off with any of the serving girls or scullery maids, as he was known to often do. Instead he stayed to laugh and drink with his friends for a bit before retiring humbly to his chambers for the night.
Loki left the dining hall shortly after Thor did. He had remained quiet and brooding as usual through the festivities. Although he had a wide throng of followers both male and female, Loki typically kept to himself during social affairs. So he was not noticed as he discreetly left his seat at Odin's table and followed his brother.
As far as Loki knew, the only people aware of his adoption were himself, Odin, Frigga, and of course Laufey, King of the Frost Giants. Thor continued to treat his younger brother the same as he always had, even as Loki's identity and concept of self collapsed around him. As Loki crept through the halls of Odin's palace toward Thor's rooms, he wondered if it would be best to simply let the thunder god continue to believe they were biological brothers. Perhaps deep down Thor was even naughtier than the god of mischief, and would find incest more enjoyable than Loki did. Loki shivered as these thoughts crossed his mind. His icy exterior melted whenever he thought of Thor in a sexual manner. He cursed to himself, wishing he had planned this out earlier. But he was now nearing his brother's chambers. There was no going back now; he would just have to wing it.
Loki entered the hallway that led to Thor's bedroom and personal lounge. He could hear water running: Thor must be drawing a bath. He tentatively approached the entrance to his brother's expansive bedroom and peered through the doorway. The clothing Thor had worn to dinner was strewn across the floor in a trail to the bathroom. The bathroom door hung open to let out a cloud of steam from the hot bathwater.
"Thor?" Loki called. There was no answer. He suddenly felt very warm and awkward. He considered fleeing before Thor knew he was there, but something made him call out again, louder this time. "Thor!"
"Yes, my brother?" Thor's deep voice echoed from the bathroom as he shut off the running water. Loki heard sloshing and splashing as the thunder god stepped into the bath.
Loki edged into the bedroom, wondering what to do next. He and Thor had never worried about modesty with each other: they were always barging into each other's rooms, even while the other was undressing or bathing. But this was the first time Loki had done so with the knowledge that the gorgeously sculpted, unclothed man before him wasn't off-limits for romance.
Loki tiptoed shyly into the sultry heat of the bathroom. Scented candles and incense burned on a shelf beneath a large mirror mounted on the far wall. Everything was decorated with gaudy gold lining that gleamed through the clouds of hot steam. Thor was relaxing in the huge round bathtub in the center of the massive room, his head leaning back against the edge. Loki could see the immaculate muscles of his chest and upper arms through the crystal clear water. He raised a thickly muscled arm in greeting. "Good evening, Loki! Did you enjoy yourself at the feast?"
Loki was starting to sweat from nerves and the intense humidity. "Of course, Thor. Did you?"
"I did." He lifted his head and eyed Loki's heavy emerald robes. "You must be sweltering, brother. Why not disrobe and join me?"
A pink flush rose to Loki's high cheekbones. His mouth felt dry. He had to attempt to act natural, though. He had swum and bathed with his brother many times before. He swallowed the lump in his throat and shrugged off his clothes, sliding quickly into the bath so Thor wouldn't see just how "sweltering" certain parts of him were becoming.
"There," Thor boomed, "that's better." He leaned back again, letting his head loll over the lip of the tub. His blonde tresses shone golden in the candlelight.
Loki shifted, glad that the lower half of his body was impossible to make out in the deep water. His fair face was creased with worry. What was he to do now? There was no place he would rather be in all the realms at this moment. But the sight of the bathing thunder god had rendered him utterly helpless.
Thor suddenly lifted his head. "You seem tense, brother," he stated. "Has something happened?"
Loki felt himself blush. "N-no..." he started to say.
But Thor cut him off. "Come, relax!" He moved through the water to Loki and grasped his shoulders, turning him around so he was facing outward. Loki froze under Thor's touch, panicking. But then he felt Thor's big, warm hands massaging his neck and shoulders, kneading his tight muscles with an expert touch. Loki closed his eyes and breathed a sigh of relief, thankful that his raging erection was now facing away from his brother.
"My, you certainly are tense," Thor declared. His thick fingers worked gently but firmly into Loki's muscles. "Let brother take care of you."
Loki's muscles tightened even more at those words. Blood surged to his cock, making it almost painfully hard. Thor's deep voice and firm touch were making it impossible for him to think of anything but being fucked long and slow by him.
After a few minutes of attempting to massage his younger brother, Thor gave up with a sigh. "You have only become tighter," he said, giving Loki's shoulders a squeeze. "But I have an idea. Why don't we move to my bed so you can relax more?"
"Thor-" Loki tried to protest, but he was cut off by the gurgle of water draining as Thor pulled the plug out of the bathtub. He panicked yet again, thinking only of what Thor would see when the water drained. He quickly climbed out of the tub, keeping his back to Thor, and snatched a fluffy red towel from the rack by the door. He wrapped it around his waist, holding it bunched in the front to to conceal his aching hard-on. The soft fabric of the towel rubbed tantalizingly against the head of his cock, making him fight back a moan. To make matters far worse, Thor was now stepping out of the bath, his wet, hard, nude form glistening in the candlelight.
Loki gulped and struggled to control himself as his brother strode towards him to retrieve a towel for himself. "Go on, make yourself comfortable," Thor offered as he dried his hair, gesturing through the doorway to his massive four-poster bed.
Loki forced his legs to take him out of the bathroom and over to Thor's bed. Thoughts of escape crossed his mind again, but something kept him from bolting for the exit. Instead, he took a deep breath to slow his pounding heart and climbed onto Thor's bed and laid face-down in the center with his head on a comfortable pillow. He tried to relax as Thor had suggested, but the pulsating erection that was now pressed beneath his stomach would not allow him to. Thor's pillow smelled of him: musky and masculine. The aroma made Loki's eyes roll back in his head and his neglected cock ooze precum.
But Loki had to force himself to lay still when he heard Thor's footsteps enter the bedroom. He peered back over his shoulder and watched Thor light a few candles on his dresser. The thunderer was still naked, his tanned skin and well-defined muscles looking even sexier in the dim candlelight. Loki quickly looked away as his brother turned to join him on the bed.
"Ah," Thor said, "you look better already." He sat down beside Loki and began to stroke the trickster's neck and shoulders again, rubbing away the tension. Loki did feel more relaxed now, but Thor's touch was utterly maddening. The muscles of Loki's upper body were soothed by his brother's touch while parts of him further south were left screaming for attention.
After a few minutes, Loki could stand it no longer. "Thor," he blurted, "there's something I must tell you."
The thunder god continued to massage Loki's muscles, working on his back now. "Yes, brother?"
Loki didn't know what to say. Thor's touch had entirely melted his brain. "I'm not your brother, Thor," he finally decided on. "I was adopted."
Thor's hands never paused in their work. "I know."
Loki lifted his head from the pillow, whirling around to face Thor. "What?"
In his shock he had forgotten the hard-on he had been so desperately trying to conceal. Now there it was, standing at attention between them. A hot red flush crept across Loki's face as he sat frozen like that, completely exposed and vulnerable.
Thor's eyes flickered downward for a moment before meeting Loki's gaze again. There was an unmistakable twinkle in his eye that made Loki's heart leap. "Yes, Loki," he said. "I have known the truth for years now. There was a night when we were young boys that I heard you murmuring in your sleep. You were speaking a language I had never heard before, a tongue that terrified me. I told Father about it the next morning because I was concerned for you. He told me not to worry about it, but I pestered him for weeks, asking how you knew such a language. And so he told me. You were adopted from frost giants, rescued from the empty ruins of their city. You must have retained some of their language in your subconscious."
Loki didn't move. He wasn't sure what to think or feel. "And you never told me?" he asked softly.
"Loki," Thor said. He reached out to tenderly brush a piece of smooth, dark hair back from the trickster's face. "You are still my brother. Nothing will ever change that. I love you and accept you, always. I'm sorry I never told you what I knew, but Father made me swear not to. It was best for you that way."
Thor's gentle touch sent an electric current through Loki's body. If his arousal had abated at all during their serious conversation, it was now back at full force. His cock throbbed before the thunder god, begging for his touch. Loki's mouth had gone dry, and he could do nothing but stare at Thor hungrily.
Thor's eyes lingered on Loki's erection much longer this time. When he looked back, a smile was curling his lip. "There is one thing that's different now, though."
Thor leaned back on the bed so his own cock was now fully exposed. Loki's eyes widened when he saw that Thor was hard now, too. Loki had seen his brother's member countless times, but never erect. Thor's cock was massive: long, thick, and rock-hard with a mouthwatering texture of ridges and veins and the foreskin pushed back to reveal a throbbing red head.
"Now that we know we're not blood-related..." Thor continued, "we don't have to feel bad about this."
He leaned in and kissed Loki, his mouth firm yet soft against his. Loki yielded immediately, lips parting to allow Thor's tongue to slip inside his mouth and dance with his own tongue. Loki moaned into the kiss, overwhelmed with the sensual pleasure of Thor's mouth.
Thor broke the kiss, leaving Loki's lips tingling. He swung a leg over Loki's lap and leaned over him in a dominant position. Loki's round green eyes had lost their typical clarity and were now half-lidded and glazed with a fog of lust. Thor held his gaze for a moment that felt like an eternity, a glimmer of mischief in his blue irises. For an instant Loki marveled at the irony of their situation: he was supposed to be the trickster here, and now Thor had him literally pinned beneath him. But his thoughts were muddled once more as the thunderer lowered his head and began to kiss and lightly nip Loki's pale neck and collarbone.
Loki couldn't help but whimper at the feel of Thor's hot breath and wet mouth on his skin. Thor began to slowly move down his body, leaving a trail of wet pink marks on Loki's sensitive skin. He caressed and groped the slim muscles of Loki's chest and abdomen as he began to suckle one of his nipples. Loki moaned loudly as Thor took his nipple into his mouth, lightly raking it with his teeth before sucking and working it with his tongue. After a while he moved to the other nipple, giving it a gentle bite before closing in to suck.
The pleasurable sensations reverberated through Loki, fueling his arousal. He began to writhe and gyrate beneath his brother, bucking his hips against Thor's. He felt the head of his cock bump against his brother's, and the contact made him ache for more. He groaned and arched his back, grinding his pelvis into Thor's, seeking that delicious friction.
Thor responded to his brother's needs, sitting up to straddle Loki's thighs. He pressed his cock against Loki's and gripped both in one big hand, beginning to pump them as one. The feeling made Loki swoon. He looked down to watch Thor's thick fingers tugging on both their cocks, their foreskins pulling back and precum mingling. Loki's manhood was by no means lacking in size, but he felt tiny next to Thor's beast of a cock. He groaned when he felt it pulsate and twitch against his, the muscles of his lower body straining to gyrate under Thor's weight.
"Thor," Loki moaned out after long minutes of this treatment. They were both grinding and humping against each other now as Thor jacked their wet, fluid-coated erections. "Thor, I want...to touch you." His arms had been paralyzed at his sides the whole time, unable to do anything but claw at the sheets under the waves of intense pleasure. But now he reached a hand up to gently stroke the tip of Thor's cock, the first time he had ever done so. Both gods groaned at the gentle contact, and Loki's fingertips were instantly sticky with precum.
But Thor maintained his dominance, letting go of their pulsating cocks and gently moving Loki's hand away. He leaned forward to kiss Loki again, snaking his tongue ever so lightly past the trickster's lips. A helpless whimper escaped Loki. Thor pulled away and gazed into his eyes, that devilish glimmer there again. "Shh, Loki," he whispered, "let brother take care of you."
And with that Loki surrendered to the power of the pleasure that was taking over his body. He let his muscles relax and his head loll back, no longer straining or trying to do anything, simply allowing the magical sensations to overcome him. He let Thor be in complete control; he let brother take care of him.
Thor noticed the change in Loki and smiled, moving down his brother's body again. This time he didn't stop until his face was level with Loki's cock. Loki gazed languidly down and watched as Thor began to grope and fondle his tight, sensitive balls. He then gripped his cock, pulling down the foreskin so the sensitive, leaking tip was exposed. Slowly, Thor brought his lips to the head of Loki's cock and kissed it. Loki moaned at the feeling of Thor's soft, wet lips and rocked his hips upward, driving some of his length into the thunderer's mouth. Thor ran his tongue along the underside of Loki's shaft, tasting and exploring. He then moved back to the head, lapping up the precum that was pouring from the slit.
Loki was panting, utterly delirious with desire. It was obvious that Thor had never sucked cock: his mouth was shy and inexperienced. But Loki soon found that Thor's enthusiasm and the size of his mouth and throat compensated wonderfully. He soon found a rhythm, pumping Loki's shaft with his fist while bobbing up and down on the head. He began to take more and more of Loki's cock down his throat, working his way down the shaft inch by inch. Loki groaned and humped into his brother's mouth, the wet heat taking his arousal to amazing heights. "Ahh, Thor," he breathed. "Yesss. Suck my cock, brother. Feels soooo good."
Encouraged by Loki's lust-laden voice, Thor began to suck harder and faster, moving farther and farther down his brother's shaft. Soon his was deep-throating Loki, burying his entire length in his throat. Loki felt Thor's lips hitting his balls as he bobbed up and down. Loki let out an animal roar of pleasure, thrusting his cock in his brother's throat. Thor barely gagged; it was like his big mouth and throat were made to suck cock.
Loki felt pressure rising from his balls and up his shaft, his orgasm approaching. He began to fuck his brother's face faster, panting and whining like a dog. "Thor," he moaned, trying to warn his brother, "Thor, I'm- Ahhh!"
His orgasm erupted from him before he could finish his sentence. His words trailed off into a high-pitched moan of absolute ecstasy. He shot load after load of cum down Thor's throat, the most intense orgasm of his life. He just kept cumming and cumming, his hips lifting from the bed and bucking all of their own accord.
Now Thor did gag, the sensation of cum shooting down his throat foreign to him. But he gulped it all down, determined to take it all for Loki.
The divine pleasure finally subsided, leaving Loki limp on the bed. Thor slowly drew his mouth off of Loki's softening cock, a thick strand of saliva connecting his mouth to the head. Thor's gaze flicked up to Loki's, the brothers staring lustfully into each other's eyes. Although Loki was spent for the moment, he did not feel entirely satisfied. The magical sensations Thor had given him had only increased his desire for the thunder god.
Thor sat up slowly, Loki following. Their mouths met in a wet, sloppy kiss. Loki reached down to find Thor just as hard as before. The thunderer couldn't help but arch at his brother's touch, thrusting his thick, meaty cock into Loki's fist. Loki gripped his brother's hard-on, reveling in the feel of its solid, textured girth. He lowered his head to return the favor Thor had done him.
Loki brought his lips to Thor's cock, shivering with pleasure at its musky scent. He slurped the precum off the head, teasing the sensitive slit with his tongue. Thor groaned, his cock twitching with need. Loki sucked his head into his mouth, letting out a muffled moan at the decadent taste and texture. Loki knew what he was doing here: he gave heavenly blowjobs, and he loved giving them. He grasped the base of Thor's cock and plunged down, filling his throat with his brother's girth. Thor growled and gripped the back of Loki's head, stroking his soft black hair as he began to fuck his face.
Loki gagged a bit at first, his eyes watering. He had never sucked a cock as big as Thor's. But he was experienced, and he couldn't get enough of Thor's delicious hard-on. He soon found a comfortable pace, slurping and slobbering to his heart's content.
Thor had never received a blowjob like this. None of the women he had bedded could take much of his massive size in their small mouths. But Loki was a tall man, quite big even with his slender build. If anyone could take Thor's cock, it was him.
Thor let out animalistic grunts and roars as he fucked Loki's face. "Ohhh, Loki," he growled. "Yeah, you little cock whore. You love sucking me off, don't you? You like being used by your big brother. Yeahh, you love it, you fucking cum slut."
Loki whimpered at Thor's dirty talk, feeling his own cock twitch again. He began to suck harder and take his brother even deeper. Thor groaned loudly, rocking his hips faster. But he surprised Loki by gently tugging the trickster's hair and pulling him off of his seething erection.
Loki stared wide-eyed at Thor, streaks of saliva shining on his chin. He was about to say something, but Thor shushed him, tenderly stroking his hair. "We both know what we want now, brother."
Loki's heart leapt, his cock stirring. He was completely hard again, still needy despite his recent release. Thor touched Loki's shoulders, gently guiding him so he was positioned face-down on the bed, just like how they had begun. Thor caressed his brother's back, hands moving all the way down to his firm, pale buttocks. Loki whined as Thor groped his ass, rolling the trickster's muscles in his palms. "Mmm, Loki," Thor rumbled, giving one cheek a swat that made his little brother jolt. "You have the finest ass I've ever seen. You wouldn't believe how long I've dreamt of doing this to you."
Thor lowered his face to Loki's bottom, filling his mouth with the flesh of one cheek and biting down. Loki moaned, arching his back. Thor chuckled and moved his mouth between his brother's cheeks, spreading them apart to access his sensitive hole. He teased the outside with his tongue, licking and tickling until Loki was lifting his ass in the air, desperate for more. Then Thor began to rim his brother in earnest, mouthing Loki's asshole as if he were making out with it.
Thor's tongue sent sparks of electricity shooting through Loki's being. He was desperately horny once again, a writhing mess under his brother's ministrations. He reached down to seize his own cock, tugging on it to relieve some of the tightness building there.
Thor began dipping his tongue into Loki's asshole, the younger man's sphincter immediately yielding to the pleasure. "Ahhh, Thorrr," Loki mewled. "Yes! Fuck me with your tongue."
The trickster was soon speechless, unable to do anything but move and whimper helplessly under Thor's mouth. The thunderer was now plunging nearly his whole tongue into Loki's ass. He paused and moved his mouth away to wet two fingers and slowly insert them into Loki's hole. The pleasure made Loki cry out, pushing his ass up and stroking himself harder. He slid his knees up underneath himself so he was kneeling with his ass on display for his big brother.
Thor chuckled again, low and lustful. "What a wanton thing you are," he rumbled, "letting your brother play with your ass." He spanked Loki again with his free hand, leaving a red mark.
Loki was panting and humping wildly, fucking his cock into his own hand. "Th-Thor," he barely managed to breathe, "please...I'm ready."
"Hmm?" Thor continued to finger-fuck him. "What's that, Loki?"
"I need...I need..." Loki couldn't think straight, his asshole clenching hungrily on Thor's fingers.
"What do you need, brother? Say it." He smacked Loki's other buttock, hard.
Loki moaned in desperation. "I need your cock, Thor!" he finally cried. "Fuck me, please!"
Loki heard another low laugh before Thor's fingers slowly withdrew from his body. "Alright, Loki." He felt the bed shift as Thor reached to his bedside table, rooting in a drawer and retrieving something. Loki shuddered in anticipation when he heard the sound of Thor opening a bottle of oil and slathering it on his cock. "Brother is going to take care of you."
Thor brought his oiled erection to Loki's bottom, sliding his thick shaft between his cheeks to tease him. Loki wriggled his rump, whimpering and whining to be penetrated. Thor finally centered his head on Loki's asshole and swirled it around the opening before ever so slowly pushing inside.
Loki's sphincter gave some resistance: he had never had something so big inside him. But Thor was gentle and patient despite his raging desire, reaching in front of Loki to play with his nipples. He buried his face in Loki's neck to whisper to him, breathing in the scent of his hair. "Mm, you feel so good, brother. Such a lovely ass." He gave it a light, playful smack. "I love you, Loki. I love playing with your ass...doing dirty things to you...fucking you. I'm going to fuck you, brother, and you're going to love it."
With that, Loki's muscles completely relaxed, allowing Thor's massive, aching member to slide inside inch by inch. The brothers groaned in unison, overwhelmed with the pleasure of their union. Thor held still for a moment to make sure Loki was okay. But the younger man began to move beneath him, fucking himself back and forth on his huge cock. So Thor began to move as well, slowly driving in and out of his brother's body. He was maddeningly, painfully hard, and Loki's ass felt like heaven around his erection.
All of the sudden Loki gave a twitch and a scream: Thor had hit his prostate. Thor began to fuck him faster, hitting that sweet spot over and over again. Loki met his strokes and continued to jack himself, letting out high-pitched sounds of ecstasy.
There was no way Thor could last long like this, but he wanted Loki to cum again before he did. He pinched Loki's nipples once more, breathing into his ear. "You like this, don't you? You like being fucked by your brother's big cock." Loki could only whine incoherently, so Thor continued. "Mm, you're such a size queen. You sure know how to take cock, Loki, you fucking whore."
Loki was racing towards his second orgasm, his bottom bumping up and down beneath Thor. His moans rose in pitch until he was screaming. "Thor!" he howled his brother's name just before releasing hot jets of cum all over his stomach and the bed beneath him.
Loki's internal muscles clenched around Thor as he came, squeezing the thunderer's pulsating cock. Thor joined Loki in ecstasy, roaring out his own release as he pumped shot after shot of hot cum inside his brother.
The waves of pleasure finally passed, leaving the brothers slumped panting on the bed. They were both completely sated, having just experienced the most intense sexual pleasure of their lives.
When their breathing and heartbeats returned to normal, Thor was the first to stir, slowly withdrawing his now flaccid member from Loki's body. Loki gave a little moan and a shudder, feeling empty without Thor inside of him. But he shivered again when he realized he was still very full indeed: his brother had completely filled his ass with cum.
Loki shifted uncomfortably beneath Thor, who was still laying atop him. "What is it, brother?" the thunderer asked, his voice low and husky.
"I have to..." Loki wiggled his bottom, indicating his problem.
It took a moment for Thor to understand. "Oh!" He quickly rolled off the bed and helped Loki up.
The trickster tried to make it to the bathroom, but he was in the middle of the hardwood floor when Thor's cum began to leak out of him. "Aah..." He arched his back as Thor's load trickled down his leg and splattered on the floor. The sensation of all that hot, sticky semen gushing from his ass was both filthy and thrilling; it was one of Loki's favorite parts of being a bottom.
Thor watched wide-eyed, amazed at the sight of his own cum pouring out of his beautiful, nude brother's ass. It just wouldn't stop. "Mmmm, soo much cum, Thor," Loki purred.
When the flow finally ceased, Loki looked at all the cum on his body and on the floor. He then looked at Thor, smiling shyly and blushing when he didn't know what to say. Thor smiled too, eyes twinkling. "How about another bath, brother?"
Loki again glanced at how messy he was and grinning sheepishly. "I think that would be a good idea."
Thor drew another bath and guided his brother into the steamy water. He then disappeared for a few minutes before returning to pamper Loki to no end, scrubbing him clean and finally finishing that massage. When they returned to the bedroom, Loki found the floor clean, the sheets changed, and the pillows fluffed. Thor tucked his sleepy brother in before putting the candles out and joining him.
Thor wrapped his strong arms around his brother and held him close. Loki sighed, nuzzling into Thor's embrace. "I'm very glad we're not really brothers," he whispered in the dark.
"Shh," Thor replied, "we'll always be brothers." He kissed Loki's forehead. "I love you, Loki."
Loki kissed him back on the cheek. "I love you, Thor." At last they drifted off to sleep in each other's arms.
