Let me tell you of the days of high adventure...
Captain America's sword sliced through the men, cutting them down like wheat in the moonlight. Beside him, the Wasp, Janet Van Dyne, swung her own blade, hacking their foes in a shower of blood and ichor. They had been set upon by bandits in a narrow pass, and now fought with the ferocity of demons.
Both had changed greatly since coming here. Cap's already olympian physique had grown even more powerful. He wore a hauberk of blue steel scales and a helm of the same metal, golden hair streaming from beneath it. As ever, he wore his indestructible shield, but he'd also taken up the sword - a sign that this place was affecting his soul as well as his body.
Janet had changed too, becoming taller, buxom, and muscular, very nearly unrecognizable from the petite fashionista she was in their home world. She wore a shaped golden breastplate over black leather and weilded her sword two-handed. She'd found her need to transform to her wasp size diminishing the longer she stayed here. The people of this world took a dim view of sorcery, and her transformation would surely be seen as such. The two of them were traveling, trying to find the rest of the Avengers, who had been strewn across this strange world.
The battle was over fast. The dead lay strewn about the rocky defile, and the rest of the bandits fled in terror.
"They'll probably spread rumours of us," Jan said breathlessly, cleaning her blade.
"Good," Cap replied. "The more dangerous we seem, the less likely we'll need to fight."
"Ever the noble hero, eh Steve?" Jan's eyes roamed her partner's powerful physique as they returned to their camp at an oasis. Cap caught her gaze and returned it. The rush of battle had brought a flush of excitement to both of them.
They tore at each other's clothes, pulling at buckles and belts, shedding layers of armour until they were naked save for boots and bracers. The kissed fiercely, voices moaning and grunting. Cap's body glistened with sweat, his cock rising like a python between his legs. Jan's curves were slick with perspiration, her nipples taut and her pussy moist. The two of them wrestled hungrily under the night sky, fighting for dominance, tongues swirling, hands groping.
Finally, Jan pinned cap to the ground and guided him into her, her voice rising to cry out as his cock filled her with its thickness... She'd been Hank Pym's wife on Earth, but here, she was a free woman and she took what she want.
Cap couldn't deny the brutal urges that consumed his psyche. They were at their peak during battle and during sex, and they were only getting stronger...

Meanwhile, under the same moon...
Jennifer Walters struggled against the manacles that held her to the obelisk. Arcane symbols had been painted on her naked skin, and she stood in the centre of a circle of power atop a mighty tower.
"Wanda," she gasped. "Please stop! This isn't like you!" Jen desperately wished she could become She-Hulk, but she knew that becoming her would be like a drug; addictive beyond belief once tasted. She-Hulk would be right in her element here: a powerful, passionate amazonian beauty, ruled by a lust for battle and a hunger for sex.
Jen had been laying low, trying to find her comrades from the Avengers, but a lawyer had little in the way of use here in this world, so she'd been working as a barmaid. Her body had become soft and zaftig, modest hips broadening and breasts swelling to give her an enticing cleavage. It was there that the Scarlet Witch found her.
Wanda laughed, her eyes alight. The magic of this place was intoxicating, and she'd become quite adept at shaping the raw energy to her needs... it also had a dark, corrupting influence on the former heroine, encouraging her to commune with malignant gods and foul demons. An army of ghouls were at her command in the catacombs of this tower, and she'd bound lesser demons to her will.
She wore a horned, glided headdress dripping with rubies and a necklace of gold that draped over her naked breasts. Bangles glittered on her fingers, wrists and arms as she gestured mystically. Her hair hung loose in frothy waves of mahogany and a string of skulls hung from her hips, along with a strip of crimson silk that hid her womanhood. She too had become curvaceous and robust, her body craving sex.
"Oh Jennifer," Wanda purred, lifting her comrade's chin with a beringed finger to look in her eyes. Jen could see an unnatural red glow in Wanda's pupils, like coals left to burn. "This is what I am. I have embraced sorcery my true calling. And you will join me as my servant, as will all of the Avengers."
"No--" Jen started to object, but was cut off by Wanda's pillowy, perfect lips pressing against her own. The former lawyer moaned as the witch's tongue slipped into her mouth, swirling like a hypnotic snake. Jen closed her eyes as she felt her lust rising, and with it, the urge to change. Wanda's fingers traced the glyphs on Jennifer's body, beginning the ritual to bind her to the sorceress's will. Jen's hands clenched, wanting desperately to break free. Her pussy dripped with lustful juices, enticed by the witch's wandering fingers. She could feel the magic tugging at her, fanning the fires within. Wanda's finger slipped into Jen's slippery womanhood. Her eyes snapped open, the brown irises shifting to green...

"Behold, the finest slaves from exotic lands," the slavemaster barked to the crowd. "The finest beauties to slake your lusts and serve your household! Ah, our first selection is a unique creature from the steamy jungles of the south!" He gestured to the curtain behind him.
It parted, and the crowd gasped, laying eyes on the figure struggling between two burly eunuchs. It was female, to be certain. The bountiful breasts and broad hips were evidence of that. But her body was covered in a thin layer of ochre fur interrupted with stripes. A tail flicked from her behind in frustration, and her catlike eyes glared at the grinning slavemaster.
Tigra would have snarled at him, but a leather gag was tied around her mouth. Her hands and feet were bound with iron manacles, making escape impossible.
"Now, shall we begin the bidding at, say, one hundred crowns?"
