Power-Woman soared high above the city. Any of the morning commuters on the streets far below waiting for the traffic light to change could look up and see a human figure in white stark against the azure sky, with a crimson cape flapping behind her, streaking toward the pinnacle of the tallest building in the skyline. Sharper eyes might pick out a similar figure not far behind, also in white and red, following the same approach vector.
As she reached the top of the tower, Power-Woman - also known as Karen Starr, in her civilian guise - gently touched down on one blue-booted toe and turned to face her pursuer and smiled fondly. About a hundred feet away and slowly closing the distance between them flew a younger version of herself - platinum blonde hair in a bob cut, bright blue eyes and fair skin, clad in a seamed white long-sleeved leotard, blue gloves and boots, a gold-buckled belt at the waist, and, slung over one shoulder with a medallion on a golden cord, a red cape that billowed behind them. Yet this costumed hero lacked the generous cleavage Power-Woman's costume put on display, having only a flat, pale chest. Likewise, where the statuesque superheroine had broad shoulders, bulging biceps that strained against her spandex sleeves, and muscular thighs, her sidekick was slender and lithe, with a narrow chest and wide hips, with the athleticism of a dancer.
"You've been getting faster!" Karen said, clapping her hands. "I'm so proud of you, son!"
Power-Boy - who everyone in the city also knew as Cal Starr - set down on the rooftop, stumbling as he landed awkwardly, and sighed. "I couldn't tell. It still felt like it took me twice as long to fly that stretch that it did you. I don't think I can fly any faster than that, Mom." He glanced down at the city stretching out below them and felt a surge of vertigo. "When do you get used to the heights?"
She walked toward him, reaching out her gloved hand. He stepped forward to take it, but the wind suddenly shifted, whipping his red cape around his bare legs tightly enough to trip him mid-step. Before he could so much as utter an "oof," he felt the air get knocked out of his lungs as his mother caught him in her strong arms. He clung to her body, which felt twice as thick as his own, and that was before accounting for her enormous breasts, which now pressed against his cheek. His mother had put on a few extra pounds since giving birth to her son eighteen years ago; a bit of flab that stubbornly clung to her belly, hips, and butt despite how actively she exercised. Just the other day she noticed that she'd even developed a bit of cellulite where her callipygean buttocks folded over her tree-thick thighs. But beneath the softness of her motherly pudge remained the steely musculature of her extraterrestrial anatomy, strengthened by a lifetime of bombardment by the rays of Earth's yellow sun. Not only was she far, far stronger than Cal, Karen towered over her son by at least a foot, adding to his feelings of inferiority.
Cal glanced up over the shapely mounds of his mother's full breasts - which fought to escape the strained confines of her leotard's cleavage window as they pushed up against him - and found himself looking into her affectionate gaze. Being held by his super-powered mother sparked a vivid sense-memory of how she would hold him when he was younger, though now that he was nearly out of his teens, it felt deeply embarrassing to him. Especially now that neither of them had anything between their bodies but two ultrathin layers of lycra.
"I've gotcha, kid," Power-Woman said. Cal knew his mother meant it to encourage him, but he couldn't help feeling like she was being patronizing. His cheeks flushed with warmth.
"Mom," Power-Boy sighed in frustration, "why do I have to wear this costume? Couldn't I have something that didn't have a big dumb cape that tripped me up all the time?"
"Aw, come on, hon," she replied. "It's not all that bad, is it? I promise you'll get used to it, once you've gotten a bit more practice in action with it. People react to the cape, you know? It's a symbol of heroism, cheesy as that might sound." She reached down to pluck his cape loose. "Also, it can get pretty chilly up on these building tops. Are you cold?" She began to rub his bare leg.
"Um," he said haltingly, "a little, maybe." As much as he hated to admit it, since they had landed he'd been doing everything he could to keep from shivering. He had goosebumps on his bare chest and upper thighs.
"Sorry, babe," she said, and drew her own cape up behind him, wrapping him in it like a blanket as she held him against herself for warmth. "Just give it a moment. I usually run a bit hot, myself. Probably the result of soaking up so many rays all these years. Our alien physiology makes us like solar panels." She gave him a sympathetic look. "Don't worry, you're still a growing boy - even more so than humans your age."
He heaved a miserable sigh. "That's what you said last year. And the year before that. I don't think I'm going to 'develop' any more than I have, Mom."
"Nonsense," she said, hugging him close. "You're just a late bloomer, that's all. Give it some time. You're probably going to end up bigger and stronger than me before you know it."
Cal clung to his mother's voluptuous body. He could feel the strength in her powerful arms around him, and somehow it made him feel even weaker. It wasn't just that he felt weaker than her by comparison - which he was by all objective measures - but being held by his super-powered mother in this way intensified his sense of inadequacy as an adult, much less as a superhero. How was he supposed to fight crime when he felt like such a Momma's boy?
And that was to say nothing of the costume he wore. Even as his mother held him tight against her, he was aware of the way his white leotard was gradually riding up between his tautly clenched butt cheeks. Every time their capes flapped he felt a cold breeze against his effectively bare bottom. And as Power-Woman's embrace pulled the thong of his leotard up tighter, it also grew more snug against his most private parts.
"But Mom," Cal whined. "Do I really need to wear this particular costume? Can't I have one that's a bit less...you know..." He winced as he squeaked out the word. "Feminine?"
Karen shook her head. "I see, girls can wear boys' outfits but boys can't wear girls' outfits, huh? Funny, that never seemed to bother you before I caught you trying on my costume in private." Cal winced at the memory of his mother unexpectedly arriving home early and finding him in her bedroom, wearing her costume and posing as he admired himself in her full-length mirror. "You seemed to think you looked pretty good in it then," she said.
Cal didn't have the nerve to admit to his mother that he'd only been trying on Power-Woman's costume because he'd intended to masturbate in it. After seeing his powerful, statuesque mother in the skintight, colorful outfit so many times, he'd grown fascinated by the sleek and stretchy texture of it, and the way it put so many of her features on display: her long, muscular legs; her ample yet athletic ass; and of course, her crevasse-like cleavage. And though he'd never admit it to anyone, something about slipping into what was clearly designed to be a woman's supersuit struck him as taboo and erotic. After feeling it hugging and caressing his body, seeing in the mirror the way it actually flattered his form in ways he hadn't expected, he had been a few seconds away from slipping his gloved fingers under the white elastic seam and stroking his penis when he heard his mother open the door.
Power-Boy's cheeks and ears heated up, and he hoped his mother wouldn't notice the rising temperature in his face. As it turned out, he had nothing to worry about - it wasn't his blushing that caught her attention.
"Cal," Karen said, looking down at him. "Are you getting an erection?"
He couldn't help it. The memory of the first time he put on his mother's supersuit was still a potent one for him, and now here he was wearing it out in public, where anyone could see him. And more humiliating, being held by his mother as she wore the same outfit, secure in her embrace, pressed up against her full breasts, and nearly wrapping his bare legs around her massive, muscular, and equally bare thigh, Cal couldn't keep his body from reacting.
He couldn't think of anything to say that would remedy the awkwardness of the moment. His mother, however, didn't react the way he expected.
"This is actually relevant to something I've been needing to discuss with you," she said. "I've been putting it off, because I didn't want to discourage you from following in my footsteps. I know you've been feeling like you don't measure up, so I didn't want to say something that would validate that fear for you. But, I don't think it's something I can avoid any longer, if you're going to go patrolling with me."
