A MagnusMagneto Attribute Transfer Story Preview
A muscular, shirtless man sits inside a circle of engraved runestones. He’s chanting a spell in a dead tongue. Scrolls of ancient text lay beside him.
Suddenly, there’s a burst of light. An ethereal sphere appears a few feet in front of the man, hanging in midair. He continues chanting, speeding up his tone, focusing intently on the orb. It pulsates, and grows in size – gaining circumference and brilliance with each second.
The man focuses his being into sustaining and nourishing the ball. A loud, droning hum fills the air, complimented by the cackles of gathering energy. Before long, the man’s efforts are answered: The ball of light transforms into a portal. The man peers into it, and only sees a shifting abyss.
Time passes. It’s a fatiguing process, but the man maintains the portal, holding out hope. Six excruciating minutes pass, testing his willpower and resolve. At last, a light flickers within the portal’s void. The man can sense an entity coming into contact with his signal.
Slowly, the light gives way to a vague figure in the distance. It draws closer, revealing an outline similar to a female human. The man steadies himself – this is what he had hoped for, but he’s still perturbed by the situation’s surrealism.
The being approaches, and the man’s hopes are met – it’s distinctly female, and human in appearance. She reaches her side of the portal, ignores the man entirely, and with long, elegant strides, steps through the window – manifesting into the man’s reality. The portal closes behind her, leaving the two of them alone in silence.
The woman has long, flowing black hair. She wears a scanty leather outfit, which is filled out by a curvaceous and muscular figure. Broad, rounded shoulders taper down to a chiseled midsection, all revealed by her top. The woman’s skin is snow white, and has no visible blemishes, scars, or imperfections. It glistens in the room’s dim light, and there’s an ethereal presence to her.
Still seated, the man glances up at the mysterious woman. His heart flutters and his pulse quickens. He had intended to summon a demonic servant, and here she was. But what was she really?
“Greetings mortal,” the woman speaks. Her voice is all at once warm, sensual, and devious. The utterance of these two words fills the man with fear and lust.
She continues: “Oh? You look so shocked to see me. Now why is that? You did summon me here after all. Remember? The succubus conjuring ritual? You know, the one requiring all the stone runes on the ground around us?” The woman chuckles, places her hands on her hips akimbo, and glares down at him. “Well, enough teasing for now. I’m here, so let’s get down to business.”
The man takes a few moments to collect himself. He stands up, dusts off, and realizes that the entity is speaking English to him, or at least is somehow instantly translating into it. He wants to ask her about this, but instead responds to her statement, “what business are you referring to?” At the very least he’ll discover if she can understand his speech or not.
The succubus is surprised at his naivety. ‘This is the only human to create a celestial portal in over 100 years,’ she thinks to herself, ‘Yet he doesn’t know what a succubus does?’ For a moment she’s annoyed, but this passes, ‘perhaps his lack of experience will prove a valuable advantage.’
“What business you ask?” She responds, “why, our game of course. We shall now conduct a series of consensual transactions, until either party is satisfied.”
The man looks down at the succubus. Despite standing a half-foot taller and carrying far more muscle, he’s unnerved by her. She has a force of presence and inner strength he’s never encountered before. The man intended to summon an otherworldly slave – specifically one that would serve to fulfill his greatest fantasies. But now he wonders how much influence he can actually exert over a being like this.
“What kind of deals are you talking about?”
“The deals? Why, they can be almost anything. We can bend the rules of metaphysics. Though everything we exchange must come from ourselves. Physical and immaterial attributes can be freely traded, as can certain… favors.” She annunciates the final word, purring slightly. He clings to every utterance – her voice is entrancing.
The man asks what she can offer him.
“What can I offer you? Well. I can fulfill your deepest, darkest desires. All of which are laid out to me like an open book.” She explains, chuckling again, bemused with her new plaything. “I am a succubus after all; and you, a mere mortal man.”
“And what exactly is my desire?” He replies, letting her lead him.
“Your desire?” She starts, gently biting her bottom lip, “simple. You want someone as beautiful as me to be far more powerful than you.”
He casts his eyes aside, and remains silent. She’s right.
“I must say you have an impressive physique for a mortal. Just how large are those arms anyways? You seem like the type who would measure them,” she snickers.
He explains they’re 20 inches in circumference. He lifts his right arm and flexes it – a large, thick throbbing bicep bulges to life. The man is proud of his muscles; he is as devoted to them as he is with his studies. Over his 38 years of age, he has he accrued great strength, knowledge, and wealth.
She already knows the answer, but plays along with her food. “20 inches you say? Very impressive for a mortal. They make my 14 inch arms look small,” she giggles, acting coy.
His eyes light up. While much smaller than his own, girls usually had to lift seriously to develop defined arms that large. A muscular woman was a rare sight – one that he privately lusted after.
“Mmm, that piqued your interest, didn’t it?” She grins, “no point in being humble, here’s a flex.” She raises her arm, grunts, and tenses it – a shapely ball of feminine power rises, pushing against her creamy skin. “Heh, look at how your eyes light up at the sight of this,” she purrs with another giggle.
The succubus senses she has totally captivated the man. “Yeah, you really like these arms of mine, don’tcha?” she taunts with a wink, “I bet you’d just love to touch them; to squeeze that warm, hard ball of power underneath my velvet skin?” Her words are like honey, and he’s desperate to drink every last drop. “And we both know you’d really like to see them become even bigger, hmmm?”
The man’s eyes light up with anticipation. He’s totally entranced by the supernatural woman. Her mere presence plays on his emotions in ways no human ever could.
The succubus continues: “Well, we can make both of those things happen. All it takes is a simple deal: trade me one inch of muscle off of your arms, and a proportional amount from the rest of your body, and I’ll let feel my newly improved guns.”
He’s taken aback by her words. What does she mean? How is this possible? He asks if the exchange is permanent.
“Hmmm? What’s that?” She pauses to process his question, “well of course it’s for keeps. You can always go back to the gym and rebuild your muscles, right?”
“Yes, I can…” he replies. “Still, I’m not sure…”
The woman lets out a sigh, “I must say I’m surprised by your reluctance. You’ll even get to watch me grow right before your eyes. What do you have to lose, really?” She smirks cruelly.
The man stammers. How is any of this possible? Yes, he did try summon this succubus here; but now this beautiful, ethereal creature was demanding that he give his muscles to her. ‘I envisioned ultimate power or the perfect bride… Not this!’ He despaired inwardly.
“It’s just an inch,” she says.
He pauses for another moment before taking a deep breath. An inch off of his arms. He’d still have 19 inches, and yet… “Why do I have to make such a sacrifice when I already went through the trouble of summoning you here?” He finally speaks up.
“Excuse me, but I’m the only one who responded to your pathetic excuse of a beacon when nobody else would.”
He gulps. He can’t verify a single thing she’s said. He has to trust everything she tells him. “Look, this isn’t fair. Shouldn’t I get to make the first proposal?”
She shakes her head and her eyes narrow, “Going to play hardball, huh? One inch for a feel. That’s my final offer. Take it, or I’ll be leaving. For good.” Her words are cold, almost harsh.
The man is overtaken with her emotional intensity, and he believes her fully. He gulps again. He doesn’t want to lose the woman, not after just having encountered her. Presuming he maintains his muscle memory and capacity to build, he should be able to regain that in a few months.
Reluctantly, he agrees to the transaction.
A devious grin meets her face. “Ah, you’ve finally come to your senses. Excellent.”
“Now what happens?”
“Now what happens?” She parrots. “Simple. Just sit back and enjoy the show.”
Both of their bodies start to glow, and a supernatural humming noise fills the air. The man feels winded and fatigued – as if his very essence is leaving him. He can feel himself physically shrinking a bit.
She feels elated beyond compare – power is flowing into her. “Mmmm… Yes… I’ve dreamed of this,” she purrs, “The feeling of feasting off of a mortal’s lifeforce; the sensation of growing bigger…” her arms swell up – their hard muscles gain an inch of circumference, “and stronger…” she moans – the rest of her body expands similarly, “as I become further engorged with metaphysical energy!”
The man’s arms shrink slightly, and he feels as if he’s a bit smaller in general. But his mind is preoccupied with too many things to register the threat. His thoughts are split between lust for the woman, and his curiosity regarding the magical transactions.
The woman’s her bosom bulges out further, pushing against the tight corset. “Sooo addicting!” She squeals, privately tensing her muscles, enjoying how they contract larger than before.
The humming noise fades, and the light leaves.
“Ah. Over so soon,” the woman is a little disappointed, but she knows there’s more to come. “Well, how do I look?” She asks, chuckling. By merely gazing into his eyes she can instantly read him. “No need to answer, I’m already well-aware that I carry this muscle better than any mortal woman could ever hope to.”
The man stares, awe-struck. In a matter of seconds, the woman in front of him has become larger, more muscular – and his opinion, more beautiful. How was this possible? Yes, he ‘gave’ his muscle to her; but like she said – it defied the rules of metaphysics. Just what else could be exchanged in these deals?
The woman’s warm voice snaps him out of his trance: “Come on over and feel this thing!”
The man obeys, lifting his hand. His fingers touch the muscle, and he’s surprised by the skin’s texture. It’s smoother than anything he’s ever touched before, ‘softer than silk,’ he decides.
He spreads his fingers around the bicep, and with both handspans, manages to scarcely contain the muscle.
The succubus notices this, “heheh, look at that, you can barely wrap your fingers around it,” she taunts.
The man is transfixed on the bicep within his grasp. It’s extremely hard, perhaps denser than his own. In the back of his mind, he ponders the differences of their physiologies. The muscle emanates a warmth that fills him completely. He clings to it, desperate to bask in the glow. Consciously, his lust for the mysterious woman increases. Yet, deep down, on a primal level, he fears her demonic powers. His fingers involuntarily quiver with anxiety; juxtaposing weakness against her strength.
“Awww, are you trembling?” She taunts with a chuckle. “You must enjoy muscles even more than I thought!”
He nods, dazed as his thoughts continue to diverge into countless directions.
She presses her advantage. “Mmm, say, don’t you want it to become even bigger? That’s right, you can even feel it grow within your grasp. Whaddya say? All you have to do is exchange another inch for that experience.” Before he can respond, she adds the killshot: “Give in. You know you want to.”
The man consents.
The woman smiles deeply. “That’s it. Good boy. Here we go.”
The humming starts again, and their bodies emanate the same glow as before. The man feels greater fatigue, and his limbs dwindle further; while she receives every drop of lost energy.
The succubus eggs him on, “feel it grow in your hands,” she grunts as her muscle fibers swell further. “Feel it become larger and harder; feel your fingers spread apart as they desperately try to cling to it.”
There’s nothing he can do to stop it. The muscle continues to grow, heating as it swells in size and power. He hears her muscle fibers cackle as they ripple with new life.
He’s too nervous to look down at his own body, but the dreadful sensation of losing his lifeforce pervades. Sweat pours down his forehead, and no amount of struggle can save him. He’s consented to the deal, and the deal must be concluded.
The man feels the bicep quiver in his grasp, and he intuits what comes next. The wriggling, writing growth fills the gaps between his fingers. His hands can barely connect at their fingertips now.
The growth ends. “Mmm, yes, that muscle is much better in my hands, don’t you agree?” The succubus asks with a giggle.
The man is entranced with the limb he just empowered. He continues to absentmindedly squeeze the bicep.
Her voice interrupts his trance, “awww, you want to keep groping it don’tcha? Bet you want to lick it and worship it, huh?” Her tone turns serious, “well, that’s too bad. It’s time for you to let go.” She pauses, sensing his yearning, “unless of course, you want to continue our transaction.”
He gulps.
“That’s right,” the succubus continues, “if you wanna keep touching it’s going to cost another inch.”
The man feels like he’s in a dream, and struggles to think clearly. Consumed with lust, he murmurs in agreement.
Her eyes light up. “Oooh, that was your fastest consent yet! Can’t say that I blame you,” she chuckles, flattered by his expressions. “Alright, here we go.”
The humming and light return. He feels his very being leaving him again.
The succubus narrates her experience: “Mmm, yes… every power up feels better than the last,” she chuckles. “I just love the sensation of your essence pouring into me — the way the hard flesh beneath my skin squirms, heating and swelling with even more,” she gasps, and her arm swells another inch in circumference, “power!”
The man watches transfixed.
She continues her monologue: “Oooh, just look at this arm! Such size and definition, absolutely delectable! I just love to flex it, squeezing the muscles nice and slow…”
With a soft grunt she tenses the limb, forcing it to reach its new maximum size. The man’s fingers can no longer touch, as the bicep between them has grown too large. Its as large as a softball, but harder than granite.
The succubus continues: “All those hours you spent grunting away in the gym, all the dieting and sacrifices you diligently made. All of that is right here now, covered by my perfect, velvet skin.” She giggles, reveling in the situation.
The man finally glances down at his body. He’s still muscular – solidly built and desirable, but he no longer exudes dominance like before. The man’s attention returns to the succubus. Her body was incredible: Her curves wide and feminine, yet fortified with a bodybuilder’s muscles, all wrapped in perfect crystalline skin.
On a lark, he raises his arm and tenses his bicep next to hers. To his surprise, horror, and arousal, her muscle is just as large as his.
“Heh, look at that dear,” the succubus starts, “our arms are now the same size. Your desire to meet a woman who is a match for you has become manifest. And yet…” she licks her lips, hungry for more, “we both know this isn’t the extent of your dreams.”
He’s lost – totally transfixed on her majesty. She’s correct: his wildest fantasies are coming true. But at what cost? The body he worked so hard to build – years in the gym, careful eating – all to achieve his prized physique. It was slipping away right before his eyes.
The succubus senses his hesitation, and knows she must press her advantage. “Come on now. Why don’t we really fulfill your fantasy – give me three more inches. See what happens.”
It’s a demand too far. “Three more inches? I’ve already given you three!” He exclaims.
Yet, as the man gazes into her fiery eyes, he’s captivated. What would happen if he gave her that much power? ‘I guess my arms would still be 14 inches. Better than nothing. Though it would set me back by a few years,’ he thinks to himself. ‘And the woman… She’s already so incredible. I may never have this opportunity again.’
Gripped by his id, the man consents.
“Incredible. You’ve agreed to even this.”
