Chapter 1


Chapter Description: A Chance Encounter in the woods...


Shadows lengthened between the oaks when Arthur heard the whisper of leathery wings cutting through still air. The young wizard froze, his satchel of gathered herbs slipping from nervous fingers. He turned slowly, heart hammering against his ribs.


She emerged from behind a massive oak trunk like sin made flesh. The succubus stood impossibly tall, easily over six feet of predatory grace wrapped in deep crimson skin that seemed to drink in the fading sunlight. Arthur's breath caught as his eyes traveled involuntarily up her form. Her legs were long and perfectly shaped, thighs thick with feminine power that spoke of countless victims crushed between them. Wide hips flared dramatically from a narrow waist, the kind of exaggerated hourglass that existed only in forbidden fantasies and demonic reality.


Her breasts were magnificent and heavy, easily larger than his head, defying gravity with supernatural pertness despite their substantial size. Dark nipples stood erect in the cool forest air, already hardened with anticipation. The succubus's face was devastatingly beautiful in that cruel way demons possessed, sharp cheekbones framing full lips curved in a predatory smile. Curved obsidian horns swept back from her forehead through cascading black hair that fell past her shoulders. A long, sinuous tail swayed behind her like a serpent preparing to strike, while massive bat-like wings stretched wide, casting her shadow over Arthur's comparatively small frame.


"Well, well," she purred, her voice like honey laced with venom. "A virgin wizard, all alone in my forest. How delicious." She took a step forward, and Arthur involuntarily stepped back. "Do you know what I am, little mage?"


"S-succubus," Arthur stammered, trying desperately to meet her eyes rather than stare at her overwhelming nudity. She towered over his five-foot-nine frame, making him feel like a child before her demonic majesty.


"Very good." Shani licked her lips slowly, savoring his fear like an appetizer. "And do you know what succubi do to pretty virgin boys we find wandering alone?"


Arthur's throat went dry. He knew, of course. Every apprentice wizard learned about demons in their studies. Succubi drained life force through sexual congress, feeding on the energy of their victims. For most men, it meant ecstasy followed by death. But Arthur had read deeper, forbidden texts that spoke of other possibilities.


"I'm going to rape you," Shani said bluntly, taking another step forward. Her wings folded slightly as she approached, tail swishing with barely contained hunger. "I'm going to pin you down right here among the roots and ride you until you're nothing but a dried husk. You'll die with my cunt squeezing the last drops of life from your pathetic virgin cock." She smiled wider, revealing sharp canines. "But what a way to go, hmm?"


For a moment, Arthur simply stood there, trembling. Then something shifted in his expression. His fear melted away, replaced by something Shani didn't immediately recognize. Excitement.

"Actually," Arthur said, his voice steadier now, "this is exactly what I've been hoping for."


His hands moved to the clasps of his robes, fingers working quickly to unfasten them. Shani watched with growing confusion as the young wizard stripped himself bare before her. His tunic fell away, revealing a lean torso marked with faint scars from magical experiments. Then his trousers dropped, and Shani's eyes widened slightly.


Arthur's cock stood fully erect, jutting proudly from between his thighs. Seven thick inches of rigid flesh, swollen with blood and leaking clear fluid from the tip. For a virgin, he showed no shame in his arousal, meeting her gaze with newfound confidence as he kicked his clothes aside.


"What are you—" Shani started, but Arthur's hands were already moving in complex patterns, fingers tracing arcane symbols in the air. His lips moved rapidly, speaking words in a tongue that predated human language. Violet light erupted from his palms, coalescing into a spinning sphere of raw transformative magic.


"Wait, what are you—" Shani tried again, but the spell hit her chest with devastating force.


The succubus's eyes went wide as the magic surged through her body like lightning through water. Her scream started deep and resonant but climbed higher, becoming more youthful and frightened as the transformation took hold. Arthur watched with growing arousal, his cock twitching as the towering demon began to shrink.


Shani's magnificent height collapsed inward, her legs shortening dramatically as she dropped from six-foot-two to five feet, then four-eight, then finally settling at barely four-foot-six. Her thick, powerful thighs slimmed down considerably, losing their crushing strength and becoming narrow, almost skinny. The dramatic flare of her hips narrowed substantially, creating a much straighter frame that barely suggested developing sexuality.

Her massive breasts deflated rapidly, the heavy flesh melting away until only the smallest bumps remained. They sat on her now-narrow chest as barely-there swells, topped with proportionally tiny nipples that looked like they'd only recently begun to develop. Her waist became even more narrow, emphasizing the prepubescent slenderness of her transformed body. Every curve that had been voluptuous and overwhelming vanished almost entirely, leaving behind the straight-lined form of early adolescence.


Shani's face underwent the most dramatic change. The sharp, predatory features softened into something rounder, younger, more innocent despite her demonic nature. Her cheekbones lost their severe angles, and her eyes grew wider and rounder, more vulnerable. Even her lips, while still full, took on a softer quality that made her look perpetually pouty. Her horns remained but shrank to tiny points barely two inches long, while her tail thinned to perhaps a third of its previous thickness. Her wings folded against her back, noticeably smaller and less imposing.


The entire transformation took perhaps ten seconds, but when it finished, Shani stood before Arthur looking like a girl who'd just barely begun puberty. She looked down at herself in horror, hands moving to her nearly flat chest, then to her narrow hips.


"What did you—" she began, her voice now much higher and lighter, stripped of its predatory resonance. "What the fuck did you do to me?"

Arthur grinned, a hungry expression that looked wrong on his previously nervous face. He closed the distance between them in two quick strides. Now he towered over her by more than a foot, his naked body looming over her transformed frame, and the power dynamic had reversed completely. He grabbed the back of her head, fingers tangling roughly in her hair, and yanked her face up to his.

"Permanent youth transformation," he said, his breath hot against her lips. His erect cock pressed against her stomach, leaving a smear of precum on her crimson skin. "You're twelve years old now, little demon. Forever."

Before Shani could respond, Arthur crushed his mouth against hers in a forceful kiss. The succubus froze in shock, her smaller body rigid against his. She'd kissed countless victims before, always in control, always the dominant presence. But now Arthur's tongue forced its way past her lips with aggressive hunger, claiming her mouth like conquered territory. His free hand grabbed her tiny waist, fingers nearly meeting around her transformed frame, and pulled her hard against him.

Shani felt his thick shaft pressing insistently against her stomach. The recognition sent a confusing thrill through her body even as her mind reeled from the violation of her form.

Arthur broke the kiss, keeping his grip on her hair. He stared down at her with eyes that burned with long-suppressed desire. "You said you were going to rape me," he growled. "But it's going to be the other way around, little girl. I'm the one who's going to rape you."

He released her hair only to grab both her shoulders and push firmly downward. Shani's transformed legs couldn't brace against his strength, and she toppled backward onto the soft forest floor with a surprised yelp. Moss and fallen leaves cushioned her impact, but before she could even think of moving, Arthur was on top of her.

His weight pressed her down, his hands pinning her narrow wrists to either side of her head. Shani realized with a start that she couldn't break free. The transformation had stolen not just her size but her demonic strength. She was truly helpless beneath him.

"This is insane," she gasped, but her body betrayed her words. As a succubus, she was built for sex, lived for it. Even in this reduced form, her transformed pussy was already growing slick with arousal. The violation, the helplessness, the complete reversal of her planned dominance—all of it fed into her supernatural nature. "You can't just—"

"I can," Arthur interrupted, grinding his bare erection against her exposed mound. "I am." He released one of her wrists to roughly grab her tiny breast, squeezing the barely-there flesh and making her gasp. "You came here to drain me dry, demon. So I'm going to take what I want first."

His hand left her chest to position himself. Shani felt something thick and hot press against her inner thigh. She looked down between their bodies and her eyes widened further.

Arthur's cock looked enormous compared to her current form. The swollen head leaked clear fluid as he positioned himself, using his free hand to guide his shaft to her entrance.

"Wait," Shani said, her higher voice wavering. "You're too big, I'm too small now, you'll—"

Arthur didn't wait. He thrust forward, burying the first few inches of his virgin cock into her transformed cunt with one brutal stroke. Shani screamed, her back arching off the ground. The sensation was overwhelming—fullness beyond anything she'd experienced in her centuries of existence. Her new body stretched around his invading length, her slick channel forced to accommodate his girth despite her drastically reduced size."Fuck," Arthur groaned, his eyes rolling back slightly. "You're so fucking tight." He pulled back slightly, then thrust again, working another inch deeper into her resisting depths. "So much tighter than I imagined."


Shani's hands flew to his shoulders, nails digging in. Her mouth opened in a silent scream as he hilted himself completely inside her with a third savage thrust. She felt impossibly full, stretched to her limits around his throbbing shaft. Her smaller body trembled beneath his, legs splaying wide in involuntary surrender.


"That's it," Arthur panted, holding himself fully sheathed in her transformed pussy. "Take all of it, little demon. Take every fucking inch in that twelve-year-old body."


He began to move, establishing a rough rhythm that showed no consideration for her adjustment. His hips snapped forward repeatedly, driving his cock deep into her tight channel with wet, obscene sounds. Each thrust made Shani's tiny breast buds bounce, the minimal flesh jiggling with the impact. Arthur's eyes fixed on the sight hungrily, watching her prepubescent body respond to his violation.


"You're—so—fucking—big," Shani gasped between thrusts, her words broken by his brutal pace. "I can't—it's too much—"


But her body told a different story. As a succubus, even transformed, she was built to derive pleasure from sex. Her pussy clenched around Arthur's invading length, inner walls rippling along his shaft with each stroke. Sensation built rapidly in her core, that familiar tension that preceded orgasm coiling tighter with impossible speed.


Arthur shifted his angle, and suddenly his cock was dragging directly across something inside her that made Shani's vision white out. Her first orgasm hit like a physical blow, back arching violently as her transformed cunt clamped down on his shaft. She screamed again, but this time it was pure ecstasy.


"Already?" Arthur laughed breathlessly, never slowing his thrusts. "Cumming already, little succubus? Does your twelve-year-old body like getting fucked by my big cock?"


He wasn't wrong. Shani had climaxed countless times in her long existence, but this was different. The reduced size of her new body seemed to amplify every sensation. Arthur's cock filled her so completely that each thrust stimulated nerve endings she'd never fully accessed before. The weight of him pressing her into the earth, the height difference that made her feel truly dominated for the first time in centuries—it all combined into an overwhelming cocktail of sensation.


Her second orgasm crashed over her before the first had fully faded, and she wailed into the darkening forest. Arthur groaned above her, his pace growing more erratic.


"Fuck, I'm not going to last," he admitted, slamming into her with increasing desperation. "Going to cum, going to fill this tight little twelve-year-old demon cunt—"


"Do it," Shani heard herself beg, her higher voice needy in a way her old voice never could have been. "Cum in me, fill me up, I need it—"


Arthur buried himself to the hilt one final time and froze. Shani felt his cock pulse inside her, felt the hot rush of his seed flooding her transformed channel. It triggered her third orgasm, and she convulsed beneath him, milking his virgin cock for every drop as waves of pleasure crashed through her smaller body.


They stayed locked together for long moments, both trembling with aftershocks. Arthur finally pulled out slowly, his softening shaft slipping free with a wet sound. His cum immediately began leaking from her well-used pussy, trickling down to stain the moss beneath her ass.

Shani lay there gasping, her transformed body marked with grass stains and Arthur's fingerprints. Her tiny breast buds heaved with each breath. She couldn't quite process what had just happened. She'd been transformed into a twelve-year-old, dominated, thoroughly fucked—and had experienced the most intense pleasure of her entire existence.


Arthur stood, his naked body still glistening with sweat. He looked down at the diminutive succubus sprawled in the leaves, cum leaking from between her thighs, and extended his hand.


"Come on," he said. "You're coming home with me."


Shani stared up at him, her wider eyes uncertain. Then, slowly, she reached up and took his hand. Arthur pulled her to her feet, and she stumbled slightly on her shortened legs. He caught her easily, one arm around her narrow waist, and began leading her through the forest toward his cottage.


The young wizard couldn't stop grinning. He'd ventured into the forest hoping to find rare ingredients, and instead he'd found something far better. A demon of his very own to play with, trapped forever in a form perfectly suited to his darkest fantasies. And judging by how many times she'd cum, she wasn't exactly complaining about the arrangement.


Shani followed, her hand still in his, her thoughts churning. She should be furious. Should be plotting revenge. But instead, she found herself already anticipating what would happen once they reached his home. Already wondering how many more times he'd pin her down and fuck her with that massive cock. Already wondering if perhaps this permanent transformation wasn't a curse at all.


The forest grew darker around them as they walked, but neither seemed to notice. They had more interesting things ahead of them.
