Amora, a.k.a the Enchantress, had heard Loki's call and was relaxing in her magical flying sled, wrapped in luxurious furs, as it carried her to his current lair. She didn't much like being summoned, not even by her most regular collaborator and occasional "friend", so the enchanted sled was perhaps not moving as quickly as it might have. Howling wind and snow whipped through the mountains of Midgard's far north, and though they did well to obscure him from mortal eyes, and even many magics, they proved no obstacle for Amora or her sled.
The sled descended into a small valley just wide enough to accommodate it, and then floated slowly into the mouth of a cave, gently settling to the ground at last. Amora could feel the warmth of the cave and removed her furs, revealing the spectacular figure for which she was known. She had one of the loveliest faces of all Asgardian women, but it was her huge breasts and remarkable curves that mystified men, Asgardian and mortal alike. She considered herself the most beautiful woman in the Nine Realms, and most agreed.
She was ever the temptress, and knew she must always maintain every advantage among her enemies, and especially with her lone (sort of) friend, and she sauntered into the cave dripping pure sex. Her hips swayed magnificently, shifting back and forth in a way that drew appreciative eyes up and down her incredible body. As clever as Loki was, she knew well that he was as infatuated with her beauty as any other man, perhaps more so.
Aside from the cloaking spell shielding the place from prying eyes, there were no other spells protecting it, and no guards, either, which immediately struck her as odd. She had never known Loki to be careless. Foolish and arrogant, perhaps, but not careless.
She stepped into the large open area that comprised most of the cave and there was no sign of Loki. Not even his helmet, which traditionally sat on the table beside his "throne" when he wasn't wearing it. She had assumed that he had called her to discuss his latest defeat at Thor's hands, or to hatch a new scheme, but now she was becoming a bit concerned. What had he done this time?
"I'm in the bedroom, if you please," he said, his voice deep and solid.
She immediately thought perhaps he was injured, or attempting some ridiculous ruse to attempt to bed her, and would be disappointed either way. She was no one's nursemaid, and would not bed Loki again lest it furthered her own ends. She had laid him spectacularly well a single time, draining his mediocre cock and balls of cum and leaving him deeply satisfied and completely limp. He had practically begged for more ever since.
Also, Amora had always preferred Thor's rugged good looks and powerful muscles to Loki's boyishly handsome face and unimpressive build, hence her reluctance to sleep with him beyond furthering her own ends. In all truth, Amora had lusted after Thor as far back as she could remember, his masculine charms and swagger having much the same effect on her that her own jaw-dropping figure had on most men.
A second---and equally important---factor, was Thor's legendary cock. Asgardian men have a reputation for being well hung among the races of the Nine Realms, and Thor was reputedly the biggest of the bunch. He was rumored to have a thick 12" cock that was always ready for action and had beaten many a pussy into submission, including Amora herself. They had shared a bed twice, both when Thor was under the influence of her magic, and both times he brutally pounded her pussy, stretching her out and making her cum more than she thought possible, leaving her bowlegged, deeply satisfied, and dreaming of future encounters. She knew how Loki felt.
Her concern grew as she stepped into the bedroom area and saw that it was fairly a mess, with tables and chairs overturned and broken, and two very large and sturdy-looking marble vanities in a dozen pieces, with Loki nowhere to be found. Her eyes drifted to the bed and things became even more curious. There were six lovely young Asgardian women in various stages of undress sprawled on Loki's huge bed, all unconscious and all seemingly smiling blissfully.
"I apologize for the dramatics but please bear with me a bit longer," Loki said, his voice deep and strong. Amora felt a tingling in her belly for a moment, but shrugged it off as her annoyance overtook it.
"Yes, yes. Hurry it up. Tell me your tale." She noticed a glamour covering a large area to one side of the bed and sat in one of the few solid chairs left, facing the glamour, then she paused for a moment. "If this is some elaborate sex-magic scheme I will banish you to Niflheim myself."
He chuckled. "I would expect no less, though I think you'll find my tale compelling," his deep voice once again causing butterflies deep inside her.
"I'll spare you the details, but I created a series of events that would convince my brother that Mangog would manifest in a cave on Midgard, deep in the bowels of the earth, and that it would be wise to confront him alone." He chuckled again, apparently at himself. "It seems he suspected an ambush, but being the hard-headed dolt that he is, he went anyway, though not alone, and with more than just his hammer. He arrived at the cave wearing his Belt of Strength, and with the great green beast in tow." He paused again. "Seems they're quite close these days."
"If all of this was to hear another of your sad tales, you needn't have bothered, and I hope you don't expect pity sex, either. You should know better." Amora made to stand, but Loki interrupted.
"Now, now. Don't be in such a hurry. 'Tis neither of those things, and I promise you it will worth the wait." Amora felt that pleasurable vibration deep inside her yet again, uncertainty clear on her face, and she sat back down, wondering what sort of magic Loki had weaved to affect her so.
"My true plan was far simpler. It was to lure my annoying brother to the cave and use ancient Fey sorceries to strip him of his power. To leave him a pathetic little whelp, as he so richly deserves."
Hearing of Thor's possible fate, Amora was suddenly upset and worried that the Nine Realms had lost its most impressive male specimen. Then the current circumstances struck her, and she asked, "But something went wrong, didn't it?" Now she was smiling. "Just as it always does."
"Indeed it did. I think perhaps, it was the addition of the enchantments on his belt, or possibly the presence of that green monstrosity, but yes, something did indeed go wrong."
Amora was smiling, truly enjoying his misfortune. "Alright. Enough with the theatrics. Drop the veil and show what you've done." There was a gentle hum, and the air grew blurry for a moment, a gentle swirl of oily colors, and then the glamour was gone, and Amora's jaw dropped open.
Standing before her was Loki in some sense, and yet not. He stood roughly 7-feet tall, with shoulders as wide as a tank, and his pitch black hair, now tinged with green highlights, was thick and wavy, running just past his powerful shoulders. His face was similarly changed. The roguish good-looks for which he was known had shifted to a more mature, more ruggedly handsome appearance that made Amora ache, and his eyes were now an emerald green so brilliant that it very nearly glowed.
Huge, thick, well-defined muscles covered his massive frame from head to toe, his size and proportions dwarfing Thor at his most powerful. His biceps were easily as big as watermelons, and the shelf of his mighty pecs reached nearly 6 inches from his ribcage. His lats cut a huge V-shape silhouette, filling out his back like thick slabs of beef, and his muscular abs were so perfectly sculpted as to defy all natural law.
Amora's eyes drifted downward, crawling over his enormous legs, as wide as pillars, and packed with dense and flawlessly shaped muscle. He shifted slightly and a ripple went across those thick tree trunks, making Amora shudder with desire, and then he shifted from one leg to the other, and something very large brushed along the front of his overlong kilt, straining against the heavy fabric.
Amora's eyes locked onto that something, faintly squinting, and Loki smiled broadly. "Ah, yes. We haven't got to the best part yet." He unfastened the thongs at either side of his waist, and his heavy kilt dropped to the floor with a gentle thud.
Loki's titanic cock swayed back and forth ponderously like a low-hanging tree limb in a strong breeze, reaching several inches below his knee, despite being slightly engorged. It was at least half-again as long as his brother's famously huge cock, and far wider, as big across as a wine bottle and nearly as thick. It was an enormous jackhammer, Manhood with a capital "M", one of the wonders of All Creation, and it redefined masculinity. To put it bluntly, there was Loki...and then every other man.
