Inevitable impact
Loki woke with a start. He observed his surroundings and came to the conclusion that he was lying in Thor's bed. Naked. He wanted to scream but failed due to the muzzle still being on his face. Thor must have put it back on while he was asleep. He wanted to lift his arms to remove it but didn't succeed. The Jotun was chained to the bed frame. Loki wasn't even capable to move his hands over his head or more then some inches. His attempt to remove his ties with magic was a very unsatisfying one and he remembered that Thor has taken away his power. Then he suddenly felt a large hand stroking his uncovered butt. When he turned his head to the side where the hand came from, he was met with Thor's lustful gaze. The god of thunder laid on top of Loki rubbing his throbbing erection against his lower body and licked his neck. The younger god looked down to his lumbar region. Thor observed that and stroked his cheek with his thumb. ''Do not be afraid my beloved Baby-Brother, I will not rape you. I will make you beg for me to mount you and to dominate you and you will be more then satisfied when I'm done with you''. And then he took of the muzzle, squeezed Loki's nose to make him open his mouth and held his jaw down with his hands so he won't bite him. Thor forced his tongue into his baby-brothers mouth and gave him a very long and sensual kiss, moaning hoarsely several times. He ended the kiss when saliva started to drop out of Loki's mouth and he felt like both of them needed some oxygen. He put the muzzle back on and adored Loki's angry and disgusted expression. ''Your struggle against my affection never ceases to arouse me, brother. I am really sorry, but I can't wait much longer. And since I can't patience myself to the point of you growing accustomed to me and my tremendous lust for you, I will have to overcome thee at thy own game''.
Loki wondered what Thor was going to do to him now and tried to express his confusion, but due to the muzzle all that could be heard was a ''Mmh?''. Thor left his chamber and came back after quite a while. He brought a container filled with test-tubes that contained many peculiar liquids, none of them familiar to Thor but all too well known to Loki. ''Let's see what your cute magic potions can do, baby-Brother''. Loki was suddenly breathing heavily, out of fear, since he knew, that some of his potions might have some terrible impacts on him, especially the ones with a black label on it. Thor was either strongly oblivious about that or just stark-mad since he showed no signs of acting with caution or knowledge of the fact that he was probably about to kill his ''brother''. He pulled a random potion out of the container as if he was drawing a card in a game. He read the handwritten note on the label. ''Shapeshifting,furry,for 2 hours. Do not use on asguardians, still in progress.'' He looked down at Loki's bewildered face and put a evil smirk on his face. ''Hmmh, I wonder what happens if I try this on you, since you've been so nice to tell me that we are not brothers a hundred times the last few days. And when we are not related you're probably really a Frost Giant.'' Thor raised his eyebrow.'' A rather small one indeed. But that makes you actually exotic and even more exciting to me, so let's just hurry with today's punishment and get to the fun part''. Once again he removed the muzzle and forced Loki's mouth open'' The small frost-giant trembled, because his past experiences with flawed potions were not all to comfortable. Of course, he never drank them. Asguardian alchemist had potion-testing wells for such cause.
You just had to pour a bit of the potion into the well and add a remarkable ingredient and the water would turn blue when the potion was flawless or black when it was flawed. Loki would never expect Thor to have a clue about such complex processes. It was too late, the potion already funneled down his throat. But nothing happened and Thor rolled his eyes in disappointment. ''You are such a bad sorcerer. I just want to have some fun with your products and what does happen? Nothing!'' He reached for the smaller ones hair to pull him up but stopped when he noticed something...fluffy on Loki's head. He brushed his hair away from it, discovered cat ears and moved his hand to Loki's bottom just to grab a long, black tail. Thor burst into laughter and he had to wipe away tears of joy. ''How strange, you are indeed a cat. But can you meow too?'' He removed the muzzle and Loki hissed at him, accidental showing his sharp teeth. ''I said meow''. Thor grasped Loki's manhood and moved his thumb up and down the tip. The god of mischief blushed and a small mewl escaped his mouth. Thor thought of this image as being too exciting for him to bear any longer and reached for a potion with the words ''Caution, flawed aphrodisiac'' written on its label. His voice was husky and full of lust when he opened Loki's mouth and said: ''Here, here kitty''. Loki, who has been looking at Thor's massive erection with fear, started to pant immediately as soon as the potion was in his stomach. His blush turned into an even darker red and he started to moan as soon as Thor started to rub his member against his own. He felt a enormous heat that was not normal for a regular aphrodisiac and his heart felt like it was burning. The up to this point more than aroused god of thunder reached for some oil in a nearby drawer and rubbed the liquid on his cock, moaning with his deep, hoarse voice. Then he took his ''pets'' growing erection into his mouth and started to suck on it hard. Loki, who was experiencing his first blow-job tried to suppress his moans and failed. Thor's erection started to hurt and he decided to do what he was waiting for since he saw Loki with the muzzle, defeated be the Avengers. He put his legs on his shoulders and slid into Loki with ease. The hot tightness made him moan deeply and he started to thrust into the frost-giant-kitty below him. These sort of feelings were completely new to Loki and so he came soon, pouring his seed on the hand that had stroked him. All the cute moans that left Loki's mouth were to much for Thor at this point and he came too, filling his lover with his hot semen.
After cleaning both of them, Thor put the muzzle back on lay down on the side and pulled his brother to his broad chest. '' Good-night Kittybrother, have a nice dream containing all the things that I might do to you'' He kissed his neck and immediately fell asleep, not noticing that Loki was already asleep, still with cat-features on his body.
