[Apologies for the length... and the girth.]
Reed Richards was watching "The Little Mermaid" with Valeria, and they were laughing at the fish during the "Under the Sea" musical number, and then Reed WAS dancing alongside the undersea creatures, his body undulating like seaweed. He could hear Valeria's giggles at the sight of him shrinking, losing strength, becoming as slender and girlish as Ariel, but Reed was still human. His breath escaped his mouth in silvery bubbles and he clutched at his throat, eyes bulging as a shadow passed over him.
He awoke with a gasp, his body tense and mind confused. He sat up and rubbed his eyes, shaking off the velvety grip of the dream... He could hear the gentle lapping of water nearby and thought he was still in the dream. The room certainly didn't look like his, even though he could barely see in the dim light. It was dome-shaped, made of some glassy material and the bed he was laying on was circular with dark satiny sheets, a far cry from the utilitarian cotton of his home. There didn't appear to be any features, other than the bed and a pond of water. "Susan?"
His voice sounded so strange! It was breathy and lilting, with a bit of a lisp. He clutched at his neck and was shocked at the soft, smooth texture of his skin. Tiny weights hung from his ears and he felt a pearl dangling from each lobe. His fingers traced down to swollen, puffy nipples on his chest and he could feel a ring of gold through both. Reed moaned in his new voice as he lingered there, twirling his fingers around the sensitive nubs. He realized he was naked, but that didn't seem to matter.
He could feel his cock stiffen between his legs, but it was a pale, pathetic thing, not the six inches he remembered... but he could remember little else. His mind was a confusing jumble of names and faces. He couldn't focus in the midst of his pleasure... but he didn't want to stop playing with himself, either.
Something stirred the water behind him, and he saw the room began to light up. He turned to see an imposing figure rising out of the pool. Water streamed down blue-skinned arms, one hand clutched a distinctive three-bladed sword, and a helmet fashioned out of the skull of some sea-beast encircled the figure's head.
"Attuma!" Reed squealed, some primal memory triggering. He scrambled to escape the bed, but was foiled by the slippery satin sheets. The figure removed its helmet and Reed gazed upon a face that was pale-blue, noble, and definitely female, though her lips were curled in a sneer.
"Not quite, little slave," she snarled, tossing her helmet and sword aside. "Although I am not surprised you think so." Reed saw she wore a skintight bodysuit with flexible armour plates. One leg was bare, and muscles rippled beneath the icy blue skin like mighty cables. He blinked. Snaking down the other leg was the thick, distinct shape of a cock! Even soft it looked menacing. Reed's heart pounded in... fear? Anticipation? Desire?
"I wrested kingship from my churl of a father when I took his head. Now Andromeda shall rule the seas!" She crooked a finger, beckoning Reed to approach.
"I thought... but Namor..." Reed protested weakly, dropping to his hands and knees. Andromeda laughed.
"Namor was a fool," she boasted. "He denied me the rank befitting me, all because I was a woman! Now I am more man than TEN of his royal guardsmen, and his kingdom shall soon be mine."
"But... but, don't you know who I am?" Reed whined, taking a tentative crawl forward.
"You are Reed-La, given to me by a comely surface-worlder along with armaments and enhancements in return for an alliance with her cabal," Andromeda said firmly. "That is all I need to know. Now attend me, slave-boi!"
Reed flinched as if struck, but responded to her command, crawling reluctantly forward to kneel before her. His mind whirled. Hadn't he been a strong, willful man? A rational man of science and... he had a... a family...
The thoughts melted away like ice in the sun as he peeled Andromeda's cock and balls from their confines, the thick, veiny monster throbbing to full hardness in his delicate hands. He caught a glimpse of himself in the water's reflection. A tumble of reddish-brown hair framed his delicate face with its wide, dewy eyes, delicate nose and full, pouting lips. Streaks of blonde grew from his temples, and his lush mane cascaded down his back. He looked like a doll, something a little girl (daughter?) would play with...
The cock in his hands overwhelmed his struggling mind. Its weight, its heat, and its smell were intoxicating. With a quiet whimper, Reed wrapped his pillowy lips around the dark head of the thick monster. Andromeda took hold of his head, running her fingers through his luxuriant mane. "Now we shall see if this 'Madame Amerika's' boasts were correct."
Without warning, she thrust her hips forward, spearing her cock into Reed's throat. His eyes widened, expecting to gag and choke on the meaty invader, but instead he felt his gullet expanding around it! It was still a tight fit, but it seemed as though he could stretch to accommodate anything! What's more, the sensation of being penetrated so roughly was like heaven. His little cock stiffened and wobbled, leaking clear juice. His eyes watered, but he wanted more. Andromeda obliged him, but she was intent on her own fulfillment, pumping into his narrow throat and grunting in satisfaction.
"Excellent!" she panted. "You may be an ignorant human child, but your cocksucking skills are the finest! Let us see if you can take me in your other hole." Andromeda wrested her cock free of his throat and forced him on his hands and knees. Reed gasped for air as she manhandled him. His mind was whirling. He had to escape! Return to his wife (why would a petite boyish slave have a wife?), his team (team of what? Other slaves?), his scientific experiments (what are those?), his... his...
He let out a moan as Andromeda's strong hands kneaded his bottom. His body may have been slender and boyish, but his butt and hips had been enhanced to plump roundness like a soft cushion. Each buttock was like a freshly raised loaf of bread, smooth and rotund, a perfect bubble-butt. His eyes widened as he felt Andromeda's saliva-slicked cock pressing into the crease between, rubbing against his asshole. He tensed in anticipation, expecting to be sodomized as roughly as he had been throat-fucked. She seemed to be waiting for him to react, though. He realized that she was testing him!
With trembling hands, he reached behind and grasped her cock. He let out a whimper and pushed back, impaling himself on her thick pole. Like in his throat, there was no pain, only wonderful fullness. His eyes rolled back as he bounced against Andromeda's hips. She took hold of him and slammed herself in balls-deep.
"Ahhh, how wonderfully tight you are, boi," Andromeda grunted. Reed's asshole stretched like a velvety glove around Andromeda's girth. It was intensely pleasureable for both of them, but Reed was unprepared for the bolts of pure ecstasy engulfing him. He gripped the bedsheets with both hands, arching his back to receive Andromeda's pounding more easily. His tongue lolled and his cock spurted weak, dribbly shots of clear, gooey semen as Andromeda's girth seemed to stretch him full. Something burned in the back of his mind, growing weaker. Each thrust seemed to push him further and further away from... from...?
Reed-La redoubled his efforts, humping back against Andromeda with zeal. "Master! Oh, master..." he moaned, his body shivering in anticipation. The confusing thoughts had drained away, leaving only his love for Andromeda.
Idly, Andromeda wondered where Namor ended up...
