Chapter warnings: This one is set post-Avengers, so you may say there are some little spoilers from Thor and from Avengers.
They shared some more encounters like the first one. Thor had improved his skills, so Loki rarely had to penetrate him. He'd do it when his brother asked him to, but those occasions were rare as well. They were simply happy with the way things had developed between them.
Loki wasn't as innocent as to believe Thor had intimate encounters just with him. The nights his brother didn't spend with him, there was a parade of women going in and out of his chambers. The god of mischief was very jealous, but he wasn't going to let his brother win. Thus, in his chambers, every night there was a different man or woman. Although, he never let another man have him. He was the one in charge when he wasn't with his brother.
But then, the dumb big oaf had to ruin everything. Odin banished Thor to Midgard, and the idiot fell in love with that commoner. Loki felt betrayed, even when their relationship was purely sexual. However, he could have forgiven that, since Thor wouldn't be allowed to see her once he'd come back to Asgard. Nonetheless, what he wasn't able to forgive was that Thor had left him alone when he needed him the most. Loki was alone in the whole Nine Realms, and his only friend -more than that, actually, but he didn't dare to go there- didn't give a damn about him. Thus, he had to do something about it.
Alas, his plans failed. The Avengers had appeared, and he was taken by Thor back to Asgard as a prisoner. There he spent his days and nights, with Mother as his only visitor. Months went by, and he never heard a word from Thor. He didn't ask Mother about him; if Thor didn't care about him, then he wouldn't care either.
It was late at night in his cell, or at least, that was what Loki thought since he could hear the snoring from the other prisoners. He should have been sleeping as well, but as he didn't do much during the day, it was difficult for him to get to sleep. Every passing day it was more difficult, but he had the strength of a god, so he didn't need that much sleep. He was laying down on his bed, looking at the ceiling, lost in his thoughts, when he heard the very familiar steps down the stairs of the dungeons. He snickered to hide his true feelings. There was a time that he would show them to him, but not anymore.
"Fancy finding you here, brother. Did you get tired of asking Heimdall about your Midgardian whore?" Loki asked, standing up and walking slowly until he reached the magic barrier which kept him there. He was delighted with the fact that Thor was shorter than him outside the cell. The god of thunder was wearing a dark blue tunic, and his face was serious.
"Don't you dare talk about her." he answered through gritted teeth.
"And what are you going to do? Imprison me? Already did. Kill me? You're not capable." he taunted looking at his fingernails. He heard Thor grunt, which made him smirk once again.
"Don't tempt me."
"As I told you, I'm not afraid of you killing me. You had your chance and didn't take it. You wouldn't dare do it here in Asgard; a mighty warrior like you wouldn't murder anyone like that. Let alone your own brother. At least, that's what everybody's still thinking." Thor touched a button, which made a hole on the barrier, big enough for him to be inside of the cell, standing in front of Loki. He was surprised, but he didn't show it on his face. "You are always so confident. I could kill you, right here and escape."
"You don't wish me dead, as I don't wish you dead." Thor replied easily, walking forward, making Loki walk backwards. The god of thunder grabbed his younger brother by the neck and lifted him lightly in the air until he was stuck to the wall. Loki looked at him defiantly. "Why, Loki? Why did you do all of that to Midgard?" Thor whispered, without letting him go.
"Why do you care? I didn't touch your new toy. Although, maybe I should have." his voice was weird because of Thor's firm grip on his neck. The god of thunder sighed.
"I didn't come here to talk about that. Cast a spell so nobody else can see us." Loki obeyed, only because he didn't want anyone else to see how easily his brother could beat him.
"Why did you come, then? I have been here for months now, and you didn't care. Why now?" Loki demanded, his breathing becoming more difficult every passing moment.
"That is not true. I have been travelling to all the Nine Realms in the name of Father. But that doesn't mean I didn't care." even when he was gripping Loki's neck, he used his thumb to caress his jawline. "I came to see if there was at least a bit of my little brother behind all that hatred." his gaze softened, but Loki wasn't going to fall for that.
"Sorry to disappoint." it was more and more difficult to talk with Thor's grip, but Loki wasn't going to give up that easily. Thor smiled.
"You are still there, brother. I can see it in your eyes." Loki smirked.
He was going to reply, but he wasn't able to do it because Thor crashed his lips on Loki's. The green-eyed god wanted to pull away immediately, but he wasn't able to. At least, he tried to convince himself that that was his first reaction because when he realised what was happening, he was kissing Thor back fiercely. There was nothing soft or gentle on their kiss, it was all tongues and teeth everywhere. Loki grabbed Thor's blond, long, silky hair and pulled it, but there was no intention of pulling his brother apart. Thor was still gripping him by the neck, but his grip wasn't as strong as before, and he was still caressing his jawline with his thumb. His tongue was dominating Loki's, but he wasn't going to give up. He still fought for dominance, even when it was a lost cause.
They stared at each other when they pulled apart, panting. Both of them refused to be the first to look away. Loki looked at his brother defiantly, while Thor looked at him as if he was trying to solve a difficult problem and failing miserably to do so.
"You should go to Midgard to satisfy your desires. Oh, wait, you can't. You destroyed the Bifrost." Loki was the one who broke the silence first since he wasn't able to stand the unresolved sexual tension between them. Thor grunted.
"If I wanted to be there, I'd be there. I am here, with you. Now, shut up." his grip on Loki's neck became firmer.
"You'd have to force me." he felt tears trying to escape his eyes from the lack of oxygen, but he fought them back. He wasn't going to cry. He wasn't weak.
Thor smiled smugly, and then took Loki's lower lip between his teeth, biting hard. Loki couldn't fight back the moan that escaped his mouth, but he didn't look away. Their gazes were still fixated on each other. When the blood came out of his lip, Thor passed his tongue, sucking it. After doing that, he forced his tongue inside Loki's mouth, exploring a territory well-known for him. Loki did the same, taunting Thor's tongue with his own. After all, he had a lot of practice these past years.
Their bodies were grinding against each other, both of their members achingly hard. They were panting, but they separated their lips just for a moment to catch their breath and then joined them once again. Using his superior strength, Thor grabbed Loki's robe and shirt and ripped them into pieces which fell to the cell's ground. He then grabbed Loki by his legs and lifted him. Loki, failing in all his attempts to fake he didn't want this with all his being, crossed his legs in Thor's back, grinding himself on his brother's hardness. Thor caressed his chest, pinched one of his nipples, and then grabbed his hips with both of his hands to put a stop to his movements. Loki grunted and Thor chuckled. Loki was so frustrated, more so because Thor had him exactly where he wanted him.
Suddenly, Loki felt how his trousers suffered the same destiny as the rest of his clothes. Thor carried him in his arms and then threw him to the bed. He was laying on his front, so he turned around just in time to watch Thor remove his blue tunic and his trousers, exposing his fully erect member. Loki's mouth watered, but before he was able to do something, Thor turned him around in the bed, biting one of his ass cheeks. Loki moaned against his pillow, his pride didn't allow him to make those noises out loud.
Loki felt then Thor's fingers covered in oil tease his entrance. Being teased in the bundle of nerves there made him grunt in anticipation. He hadn't been taken by any other man than Thor, and they were oh so young when that happened. He would only allow Thor to penetrate him, so even though he had laid with a lot of men, he was the one who took them.
"Let me hear you, brother." Thor commanded with a raspy voice.
Loki opened his mouth to give him an excellent remark, but at that exact moment, the god of thunder pushed his finger inside him. There was nothing to hold back his moan, and the sound echoed in the prison cell. He felt Thor's grin on his back, before he bit it, leaving a mark. Loki remembered exactly how his brother had improved his skills during their youth, but at that moment, it felt like he was an expert. His slick fingers moved inside and out of him easily, and Thor circled them and expanded his entrance the most which his fingers would allow.
Loki was a panting, shivering mess when Thor pulled out his fingers. He didn't have time to recover, as Thor thrust inside him forcefully. He felt Thor's grunt while he penetrated him, and Loki couldn't help but smirk.
I can still drive him crazy…thought Loki, although there was little room on his brain to think about anything else than the sheer pleasure he was feeling. Thor slammed into him, hitting his prostate time and time again, making him moan as no one else can. Loki gripped the white sheets of his bed firmly, while he tried to suppress any indication of the pleasure that was waving all over his body.
Suddenly, Thor grabbed his neck, making Loki's back collide with his chest. The god of thunder was still thrusting hard inside him, and this new angle was making him feel like he died and went to Valhalla.
"Tell me how much you like how I fuck you." whispered Thor in his ear, blond hair mixing with the raven one.
Loki didn't have time to come up with a reply, since Thor kissed him passionately. Then he moved to his neck, kissing, licking and biting. Loki was sure that he was going to have marks the following day, but he didn't find it in himself to care. If it weren't for Thor's firm grip on his neck and one side of his hips, he would have collapsed again on the mattress, since he didn't have the strength to stay like that. He didn't have the pillow to muffle his moans either, which surely was Thor's primary goal. He was a big, arrogant oaf, and he loved hearing how he drove Loki crazy.
Loki felt he was getting closer and closer to his climax. He wanted this to last longer -forever, if possible- but the way Thor was hitting his prostate with every single one of his thrusts into him wasn't going to let him. Thus, instead of trying to avoid the inevitable, he just let go, screaming Thor's name with each movement he felt until he finished. After a few thrusts more, the god of thunder followed him, and they both collapsed on the tiny bed. Loki fell on his cum, which wasn't pleasant, so he used his last bit of energy to clean it up with his magic. He wasn't able to do much magic on his prison cell, but that was so simple that he was able to do it without problems.
Thor pulled out from him, laying on his back right next to him, while Loki just curled up. He didn't want to see his brother. Truth was, he didn't want Thor to see him. If he were to see him, he would have known how fragile and vulnerable he felt, and that was something he wasn't keen to share.
"Did you really want me dead?" asked Thor in a whisper, pressing his bigger body to his back and passing one of his arms on top of him to hug him.
"What do you think?" answered Loki rhetorically, trying to find his normal voice once again.
"When you sent The Destroyer to Midgard…you never answered my question. What have I done for you to hate me so much?" it felt like Thor was hurt, but probably that was just his wishful thinking.
"I didn't hate you back then." he wasn't going to tell him that he could never hate him; that even now when he was embraced by him in a prison cell, he just wanted Thor to love him as much as he loved him.
"Then, why did you…?"
"Enough with the questions. You got what you looked for. You have satisfied your needs. You may leave now." Loki interrupted him because he wasn't able to hold himself any longer.
"I didn't come here just to satisfy my needs. Although you must admit, you do a great job fulfilling my wishes and desires." he kissed him gently on the shoulder. "I wanted to see you, to talk to you… I want my little brother back."
"I am not what you want. I will never be again. You can thank your father for that. Now, leave, before I do something I shouldn't…"
"Alright, I'm leaving now. But I'm coming back to you. I'll always come back to you, Loki." he kissed him gently on the cheek.
Thor got up, put on his clothes and disappeared away from the dungeons. When Loki was sure that no one else was able to hear him, he whispered in a shaky voice:
"I didn't want to hurt you."
