Loki lay along Thor's body, and felt for the first time in many months, safe. Here in this tiny chamber, with Thor and no-one else, his nakedness pressed down along the powerful torso, he was free to feel and think what he pleased.

What he felt was the pressure of Thor's hot genitals against his, an island of softness on the hard body of the thunder god, but rapidly hardening. Loki writhed his own body down on Thor's, pressing their erections together, and being rewarded by an involuntary grunt from Thor. Thor's blue eyes were luminous in the low light, gazing up at him with a sort of wonder that made Loki forgive him for a few more of the things that his big brother had done over the last few years. Loki tried hard to keep himself from dreaming, from making illusions, but it was hard to focus, and a startled utterance from Thor made him realise that he had not entirely succeeded. Loki kissed Thor's eyes closed and said, "I'll try not to do that."

"No," the quiet word surprised Loki. Thor went on, "This is what you are. Do not change yourself for me. Just be."

"Don't tell me that." Loki felt the usual iron control over his illusions slipping rapidly away, and clung to Thor's body. He saw Thor's eyes widen and Thor asked, "Why is there a horse in here?"

Loki laughed and said, "Come with me. I'll show you a thousand worlds."

He gathered Thor's belief around him like a cloak and let his mind run free, and Thor gasped as the room disappeared around them, and they were falling through an endless ocean of stars. Then they changed into two horses with wings, Thor tumbling head over heels until he realised he had to flap his wings to return to Loki. He flapped laboriously up to reach the dark horse that was his brother. Loki laughed and said, "You're shocking at this. There's no air, we're in a vacuum, why are you flapping?" "You are!" cried Thor. Loki laughed again, and said, "I do it for show. You do it for… I don't know!"

Thor cursed him and flapped up beside him, and Loki breathed, "You would be white."

Thor looked down at himself, a glow of hooves and wings in the darkness, "You are doing this, not me!" Loki slipped around him and said, "Then why be afraid? Nothing will happen to you." He flew in front of Thor and they collided, then they were back in the tiny secluded bedroom, in their own bodies, pressed together. Thor looked up at Loki and said, "Why are we back here?"

"Just letting you catch your breath," whispered Loki and kissed him, wrapping his arms around Thor's body… and then they were a thousand leagues under the sea and Loki was an octopus with eight powerful tentacles, Thor a dolphin struggling armless and terrified in his grasp, unable to breathe. The octopus pushed a tentacle into Thor's mouth and another tentacle wrapped around him, slipped inside his pouch and entwined his penis, squeezing and massaging it until Thor forgot that he had to breathe and moaned in pleasure, pumping his body against Loki's. The tentacles tightened around Thor's body to the point where he screamed in pain… and was suddenly a baby fox being squeezed in the talons of a huge eagle, rocketing above the mountain peaks, until Thor bit the claw that held him and was falling, tumbling, yelping with fear, a thousand feet above the rocks and falling fast... into the bed in the chamber once more.

Thor sat up gasping with fear, pushing Loki aside, but then grabbing him by the hair, panting to get his breath back. He stared at Loki, who asked, "Had enough?"

Thor leaned forward and pressed his lips to Loki's in a desperately passionate kiss, and demanded, "Give me more!"

Loki's eyes widened in delight and Thor was suddenly a huge tree in an ancient forest, with a vine growing too-quickly up his branches and suffocating him, its tendrils pushing into him, invading and expanding into every crevice in his trunk and lower branches, flowering before his eyes into Loki's face, eyes dark and thrilled.

"Oh God," whispered Thor. He tried to grow out of the grasp of the vine, pushing himself up and up into the blue sky, then suddenly bursting free to dive into the ocean from a great height, a huge whale breaching the waves and sinking into the cool, embracing depths…. He found a female and entered her, his enormous penis pumping and hard inside her. She rolled beneath him, impossibly, and clasped him again, with tentacles that a she-whale should not have….

And suddenly Thor was back in the tiny chamber, pumping wildly into his brother's body, the thrust and slide out of his flesh into Loki's accompanied by his own moans of delight, and Loki's gasps of pleasure. Loki pulled his face close and said, "Watch me," and Thor found his eyes unable to escape the dark gaze of his brother. Thor felt his body thrusting again and again, out of control, as Loki watched him, and then the thunder god climaxed in a burst of lightning and thunder in the tiny chamber. Loki cried out and vaguely Thor realized that his lover had come, too.

When the climax had released them both slowly back to sanity and the smoke had cleared so he could breathe again in anything but harsh gasps for air, Thor pulled Loki close to him and whispered, "I am lost in you. And now I cannot be anyone else's."

Loki's dark eyes glowed like two black holes, haloed by a corona of soft, pale green light, as he replied in a whisper, "You never were anyone else's."
