A story of a couple discovering a bag of magical sweets that modify their bodies and personalities. The sweets only have temporary effects before the changes reside again.

Chapter 1: The Transformation Presentation

The bell above the door of Professor Blackwood’s shop jingled softly as Chris and Bea stepped inside, the scent of aged parchment and something sweetly intoxicating wrapping around them. The dim lighting cast long shadows across the shelves, which were cluttered with oddities—glass phials of shimmering liquids, leather-bound grimoires, and strange artifacts that hummed with latent magic. Chris adjusted his glasses, his fingers brushing against the edge of a velvet-lined display case where a silver dildo pulsed faintly with an inner glow.

“This place is… something,” Bea murmured, her eyes scanning the shelves with a mix of fascination and amusement.

She reached out, fingers hovering over a small, ornate jar filled with what looked like tiny, iridescent candies. “What do you think these are?”

Chris hesitated, his analytical mind already dissecting the possibilities. “I don’t know, but I’m pretty sure Professor Blackwood wouldn’t keep them out if they weren’t safe.” His voice was steady, but his pulse quickened. There was something about this shop—something that made his skin prickle with anticipation.

A voice, smooth and amused, cut through the silence. “Ah, you’ve found my little experiment.”

Chris turned to see Professor Blackwood emerging from the back room, her dark robes swirling around her like smoke.

She was an older woman, her sharp features framed by silver-streaked hair, but there was a mischievous glint in her eyes that made Chris’s throat tighten. She smiled, her lips curling into something knowing.

“Ah, my newest batch of *Sweet Surrender* candies,” she said, plucking the jar from Bea’s fingers with a delicate touch. “A little treat with… *side effects.*”

Bea laughed, her voice light. “Side effects? Like what? Do they make you fart rainbows?”

Professor Blackwood’s grin widened. “Oh, nothing so trivial.

These are *transformation* candies.” Professor Blackwood’s voice dropped to a sultry purr, her fingers tracing the rim of the jar. “One bite, and you’ll find yourself… *different.*”

Chris felt a jolt of heat shoot through him, his cock twitching in his slacks. He swallowed hard, his fingers flexing at his sides. “Different how?”

The professor’s eyes flicked to him, dark and knowing. “Why don’t I show you?”

She plucked a candy from the jar—a small, shimmering square of what looked like spun sugar—and popped it into her mouth. For a moment, nothing happened.

Then, the professor's body shuddered, her spine arching as if an invisible hand had yanked her strings. Her robes rippled, the fabric clinging to her curves before dissolving into thin air, leaving her standing there in nothing but a sheer black slip.

Chris’s breath hitched. The woman before them was no longer the silver-haired professor—she was a vision of sinful perfection. Her body had smoothed, her skin now flawless and glowing, her curves lush and exaggerated. Her breasts were full, heavy, the nipples already hard and pressing against the delicate fabric of her slip. Her hips flared out, her ass round and firm, begging to be gripped.

Her thighs were thick, her pussy already glistening through the sheer fabric, the outline of her slit visible, swollen and needy. Her face was still hers—sharp, knowing, but younger, softer, her lips full and parted in a breathy gasp.

Chris’s cock throbbed painfully in his pants, his throat dry. *Fuck.* He had never seen anything so perfect. So *wrong.* So *right.*

Bea let out a shaky laugh, her fingers twitching at her sides. “Well, that’s… definitely a side effect.”

The professor—no, the *succubus*—smiled, slow and wicked.

Her tongue darted out to wet her lips, and Chris’s cock jerked in response, precome already dampening his boxers. He could *smell* her now, something sweet and musky, like ripe fruit left in the sun too long. It made his head spin.

“You like what you see?” she purred, rolling her hips just enough to make the sheer fabric of her slip ride up, baring the smooth, glistening skin of her inner thighs. Her fingers traced the neckline of her slip, teasing the swell of her breasts before slipping beneath the fabric to pinch her own nipple. A soft, breathy moan escaped her, and Chris’s knees nearly buckled.

His cock was rock-hard now, straining against his zipper, begging for release. He could feel the heat radiating off her, the scent of her arousal thick in the air—sweet, musky, *intoxicating.*

Bea’s fingers twitched at her sides, her own breath coming faster. “Fuck,” she whispered, her voice rough with need. “That’s… that’s *insane.*”

The succubus—*Professor Blackwood’s* transformed body—smiled, slow and wicked. “Would you like to try one?” she asked, her voice a sultry purr.

The question hung in the air, heavy with promise and danger. Chris felt his pulse hammering in his throat, his cock throbbing painfully against the confines of his slacks. He glanced at Bea, whose cheeks were flushed, her lips slightly parted as she stared at the transformed professor. There was a hunger in her eyes that mirrored the fire burning inside him.

Bea reached out, her fingers trembling as she plucked a candy from the jar. She held it up, the shimmering sugar catching the dim light of the shop. "What do you think, Chris?" she asked, her voice breathless. "Should we?"

Chris swallowed hard, his mind racing. This was reckless.

This was *stupid.* This was the most exciting thing that had ever happened to him.

Bea licked her lips, the gesture slow and deliberate, before slipping the candy into Chris’s palm. Her fingers lingered against his skin, warm and trembling, as if she were just as nervous as he was. The sugar square was cool against his flesh, humming faintly, like a live wire.

Chris stared at it, his pulse hammering in his throat. He could feel the weight of Professor Blackwood’s gaze—no, the *succubus’s* gaze—on him, heavy and expectant. Her lips were parted, her tongue darting out to wet them again, as if she could taste his hesitation in the air.

*Fuck it.*

He popped the candy into his mouth.

The moment it touched his tongue, fire erupted in his veins.

Chris’s back arched violently, a guttural groan tearing from his throat as his cock *exploded*—thick, scalding ropes of come blasting against his zipper, soaking through the fabric in seconds. His vision whited out for a heartbeat, his fingers clawing at the edge of the counter as his entire body convulsed, the pleasure so intense it bordered on agony. *Fuck—fuck—* His hips jerked forward involuntarily, grinding against the air as his cock pulsed again, another hot spurt painting the inside of his boxers, the wet heat spreading down his thighs.

Bea’s breath hitched beside him, her hand flying to his arm. “Chris—?” But her voice was swallowed by the sound of his ragged gasps, the way his knees buckled, his free hand slamming against the glass display case to keep himself upright.

Chris gasped, his cock swelling painfully against his zipper as the succubus sank to her knees before him, her dark eyes locked onto his with a predatory hunger. Her fingers—long, elegant, and now tipped with dark red nails—curled around his belt, yanking it open with a sharp *snap* that made Bea’s breath catch in her throat.

The succubus didn’t hesitate. Her lips parted, slick and glistening, as she leaned in, her hot breath ghosting over the straining fabric of his boxers. Chris’s hands flew to her shoulders, fingers digging into the soft flesh as she hooked her thumbs into the waistband of his slacks and dragged them down in one fluid motion.

His cock sprang free, thick and flushed, the head already weeping with need.

Before he could even process the sensation, her tongue was on him—hot, wet, and relentless. She licked him clean in one slow, deliberate stroke, her tongue swirling around the sensitive tip before dragging down the length of him, collecting every last drop of his release. Chris groaned, his fingers tightening in her hair as her mouth closed around him, sucking gently, her cheeks hollowing as she worked him deeper.

Bea’s breath hitched beside him, her fingers pressing to her lips as she watched the succubus take him in, her own thighs squeezing together. “Oh my God,” she whispered, her voice thick with arousal.

The succubus pulled back just enough to look up at him, her lips glistening, her dark eyes burning with hunger. “Mmm,” she purred, her thumb brushing over the head of his cock, spreading the slickness.

“Mmm,” she purred, her thumb brushing over the head of his cock, spreading the slickness. “Delicious.”

Chris could only stare, his mind wiped clean by the overload of sensation. He was still coming down from the violent, candy-induced orgasm, his body humming with a strange, new energy. His skin felt too tight, his senses dialed up to eleven. The smell of her—sweet musk and sugar—was everywhere.

Bea watched, her breathing shallow. She bit her lower lip, her eyes darting from Chris’s flushed face to the succubus kneeling between his thighs. A war was happening behind her eyes—curiosity, arousal, a flicker of fear. She reached out, her fingers hovering over the open jar on the counter.

“What would it do to me?” Bea’s voice was barely a whisper, but it cut through the wet, sucking sounds the professor was making.

The succubus pulled off Chris’s cock with a soft pop, leaving him throbbing and exposed. She looked over her shoulder, a strand of saliva connecting her lip to his glistening shaft. “Why don’t you find out, darling?” Her voice was a honeyed trap. “It’s different for everyone. A reflection of… hidden appetites.”

Bea’s hand trembled. She looked at Chris, searching his face for an answer. His mind was fogged with lust, but he managed a jerky nod. “Do it,” he rasped, the words scraping his throat raw. The part of him that was always anxious, always measuring risk, was buried deep under a landslide of pure want. He needed to see what she would become.

With a sharp intake of breath, Bea snatched a candy from the jar and put it in her mouth.

The effect was instantaneous, but different.

Bea gasped, her back arching not in pain, but in a slow, sinuous stretch. A low, pleased hum vibrated in her chest. Where Chris’s transformation had been a violent eruption, Bea’s was a blooming. Her sweater and jeans seemed to melt away, not vanishing, but transforming into something else—a sheer, pearl-colored chemise that clung to every new curve.

Her body filled out, her hips widening, her ass rounding into perfect, plump spheres. Her breasts swelled, heavy and full, the nipples pert and pink against the fabric. Her skin took on a dewy, opalescent sheen. Her hair, once a simple brown, now fell in waves of honey-gold past her shoulders. She looked like a vintage pin-up dream, soft and inviting, but her eyes… her eyes held a new, hungry confidence.

“Oh, wow,” Bea breathed, looking down at herself. She cupped her own breasts, her thumbs brushing over her nipples. A shiver racked her body. “Chris… I feel… insatiable.”

The professor rose to her feet, a wicked smile playing on her lips. She moved behind Bea, pressing her lush, transformed body against Bea’s back. Her hands slid around Bea’s waist, cupping the soft weight of her new breasts, squeezing possessively.

“See?” the professor murmured into Bea’s ear, her voice thick with promise. “The candy doesn’t lie. It shows you what you really want.”

Bea’s head fell back against the professor’s shoulder, a moan escaping her as the professor pinched and rolled her nipples. Chris watched, utterly transfixed, his re-hardened cock jutting out aggressively. This was his wife, yet it wasn’t. This was a fantasy made flesh, and the filthiest part of his brain was screaming in triumph.

“Touch her, Chris,” the professor commanded, her dark eyes locking onto his. “Don’t just stand there with that beautiful cock. Come and claim your wife.”

The words broke his paralysis. He stumbled forward, his hands finding Bea’s hips. The sheer fabric of her chemise was slick under his palms. He yanked it up, revealing the smooth, bare mound of her pussy, already glistening with wetness. The scent of her—sweet and heady, like orchids—flooded his senses.

“Fuck, Bea,” he groaned, leaning in to lick a hot stripe up her slit.

She cried out, her hands flying back to grip the professor’s thighs. “Yes! Oh God, yes!”

Chris dove in, eating her out with a frantic, desperate hunger. He licked and sucked, driving his tongue inside her, lapping at her clit until her legs shook. Her taste was different, intoxicating, like nothing he’d ever experienced. The professor watched over Bea’s shoulder, one hand still mauling Bea’s tit, the other snaking down to rub slow, tight circles over Bea’s clit in time with Chris’s tongue.

“She’s so wet for you, Chris,” the professor taunted, her voice a sinful rasp. “She’s dripping. You want to fuck her, don’t you? You want to shove that big cock into this pretty, transformed pussy and ruin her?”

Chris pulled back, his chin glistening. “Yes. Fuck, yes.”

“Then do it.”

He didn’t need to be told twice. He straightened up, his hands shaking as he guided the head of his cock to her entrance. He looked into Bea’s eyes, now dark with wild need. “Bea…”

“Just fuck me, Chris!” she begged, pushing her hips back against him.

He slammed into her in one brutal, deep stroke.

The sound she made was pure, raw sex—a guttural scream of pleasure that echoed off the shop’s cluttered shelves. She was impossibly tight, hot, and wet, her transformed body gripping him like a velvet fist. He buried himself to the hilt, his balls slapping against her, and stayed there for a second, overwhelmed.

“Move!” the professor hissed, biting Bea’s shoulder. “Fuck her like you mean it!”

Chris obeyed, pulling out and driving back in, setting a punishing rhythm. The shop filled with the sounds of their coupling—skin slapping against skin, ragged gasps, filthy, encouraging whispers from the professor. Bea reached back, her fingers tangling in Chris’s hair, pulling him closer as he pounded into her.

The professor’s hands were everywhere, teasing them both, pinching, rubbing, stroking. She brought her slick fingers, wet from Bea’s pussy, to Chris’s mouth. “Suck,” she ordered. He did, tasting his wife on the professor’s skin, the dual flavor pushing him closer to the edge.

“I’m gonna come,” Chris warned, his thrusts becoming erratic, deeper.

“Not yet,” the professor said. She shoved Bea forward, bending her over the glass display case. “Now. Harder. Give it to her.”

The new angle was deeper, more animal. Chris gripped Bea’s hips, his fingers digging into the soft flesh of her incredible new ass, and fucked her with everything he had. Bea’s cries were constant now, a stream of broken yes, yes, fuck, right there that drove him insane.

The professor knelt behind Chris, her hands spreading his ass cheeks. He felt a cool, slick finger press against his hole, followed by the sudden, shocking intrusion of her tongue. He shouted, his entire body seizing as she rimmed him with expert, filthy precision.

It was too much—the feel of Bea’s pussy milking his cock, the professor’s tongue working his ass, the surreal, magical heat of the room. With a final, ragged roar, Chris came, pumping his load deep into Bea in hot, pulsing jets. His vision blurred, his knees buckled, and he collapsed forward over her back, spent and shuddering.

Bea climaxed a second later, her inner walls clamping down on him, milking every last drop as she sobbed his name into the glass case.

The professor stood, licking her lips, a satisfied, devilish smile on her face. She watched them, two transformed, trembling creatures clinging to each other in the aftermath. The air still crackled with spent magic and sex.

Bea, panting, turned her head to look at the jar still sitting on the counter, now half-empty. Her new, gold-flecked eyes held a dazed, hungry glow.

“Chris,” she whispered, her voice husky and strange. “We… we need to take some of these home.”

Bea’s whisper hung in the air, a siren call that burrowed straight into the fevered core of Chris’s mind. He could only grunt in agreement, his softening cock still sheathed inside her, their bodies slick with sweat and come. The world had narrowed to the throbbing heat between them and the half-full jar of shimmering candy on the polished wood counter.

But they weren’t alone.

A low, throaty chuckle came from behind Chris, followed by the sensation of sharp nails trailing down his damp spine. He shivered, the aftershocks of his climax mingling with a fresh jolt of arousal.

“A wise idea, my dears,” Professor Blackwood purred, her transformed body—that impossible succubus vision—pressing against his back. Her heavy, perfumed breasts mashed into him. One hand slipped around his hip, her fingers finding the moist, sensitive join where his flesh was still connected to Bea’s. She rubbed a slow, filthy circle there, collecting their mixed fluids. “But the show isn’t quite over. The magic… lingers. And so do I.”

Her other hand cupped his chin, turning his head until he was forced to meet her gaze. Her eyes were pools of molten darkness, glowing with an inner, hungry light. “You’ve had your fun,” she breathed, her lips an inch from his. “But my little demonstration requires a… gratuity. The effects are fading. I can feel it.” She gave a slight, full-body shudder, and for a fleeting second, the lush curves seemed to waver, the youthful perfection thinning at the edges like smoke. “I intend to enjoy every last second of it. And you two are going to help me.”

Bea, still bent over the glass case, whimpered as Chris’s cock slid from her. She pushed herself up, turning, her new body moving with a fluid, lazy grace. She looked from the professor’s predatory stare to Chris’s overwhelmed face. A slow, wanton smile spread across her own perfect lips. “How?” The single word was ripe with curiosity and a newly awakened boldness.

The professor’s answering smile was all teeth. She stepped back, swaying her hips toward a heavy velvet curtain that partitioned a back room from the shop. “My office.Now. Bring the jar.”

The command was absolute. Chris, his mind hazy with magic and sex, fumbled for his discarded slacks, stepping into them without buttoning the fly. His spent cock ached, but a low thrum of renewed interest was already stirring. Bea simply plucked the jar from the counter, cradling it like a sacred relic, and followed, her bare feet silent on the worn floorboards. Chris followed, his eyes glued to the hypnotic sway of her transformed ass.

The back office was a cluttered sanctuary of the arcane. Bookshelves groaned under leather-bound tomes. Strange artifacts littered every surface: a brass astrolabe, a crystal skull winking in the lamplight, a collection of ornate, polished phials. And on a small, elegant desk of dark wood, two items sat prominently.

One was a bottle of oil, the liquid inside shimmering with a faint, opalescent sheen. The other was an anal plug, but like nothing Chris had ever seen. It was blown from what looked like solid, flawless glass, sculpted into a slender, tapering shape. But its core wasn’t empty; it swirled with a captive nebula of deep violet and gold, swirling lazily as if alive.

Professor Blackwood went directly to it, her movements becoming quicker, more urgent. The wavering at the edges of her form was more pronounced now. She snatched the bottle of oil, pouring a generous amount into her palm. The scent that filled the small room was spicy and electric, like ozone and cinnamon.

“You,” she said, pointing a gleaming, oily finger at Chris. “On your knees. Behind me.”

Chris obeyed, the command short-circuiting his usual anxiety. He dropped to his knees on the plush rug, the rough texture a stark contrast to the surrealism of the moment. The professor turned her back to him, presenting the impossible perfection of her ass. She bent forward, bracing her hands on the edge of the desk, and looked over her shoulder. Her dark hair fell across her face. “Bea.Watch. Learn. And be ready.”

With that, she reached back with her slick hand, guiding the tapered tip of the glass plug to her asshole. Chris watched, breathless, as the tight, wrinkled pucker yielded to the slick intrusion. She fed it into herself slowly, a hiss of pleasure escaping her lips. The glass disappeared into her, inch by inch, until the flared base, shaped like a stylized star, sat snug against her skin. The swirling colors within the glass pulsed, glowing brighter.

A shuddering wave passed through the professor’s body. The wavering stopped. Her form solidified, the succubus-like vitality burning brighter, fiercer. “Oh, yes,” she moaned, rolling her hips. “That’s it.The anchor. Now…” She locked eyes with Chris. “Fuck my ass. Hard. I want to feel every inch before this skin turns back into wrinkled old leather.”

The raw obscenity of the command sent a bolt of pure lust straight to Chris’s cock. It was fully hard again, jutting from his open flies, aching and ready. He shuffled forward on his knees, his hands gripping the swell of her hips. He guided himself, the head of his cock nudging against the glass plug now buried inside her. The barrier was both strange and intensely erotic.

“Not around it, you eager boy,” the professor snarled, pushing back against him. “With it.Beside it. Stretch me. Fill me. Now!”

Chris drove forward. The resistance was incredible, a crushing, tight heat around the unyielding glass. He groaned, a raw, animal sound, as he buried himself to the hilt in her ass. She was impossibly tight, a vise gripping both his flesh and the cold, hard glass. He could feel the shape of the plug alongside his cock, a dual fullness that made his head swim.

“Fuck! Yes!” the professor screamed, her knuckles white on the desk. “That’s it! Don’t you dare be gentle!”

Chris began to move, setting a brutal, piston-like rhythm. The sounds were filthy, wet, and raw—the slap of his thighs against her ass, the choked grunts from both of them, the faint, crystalline chime of the glass plug shifting inside her with every thrust. The swirling colors in the plug flared like a miniature supernova, casting shifting violet and gold light across their sweating bodies.

Bea stood to the side, one hand stroking her own ample breast, the other buried between her own thighs, rubbing furious circles on her clit as she watched her husband ravage the magical professor. Her breath came in sharp, little gasps.

“Harder, Chris!” Bea urged, her voice trembling with voyeuristic ecstasy. “Make her feel it!”

Chris obeyed, his world narrowing to the animalistic drive to pound, to claim, to fuck this magical creature into oblivion before her spell broke. His balls tightened, slapping against her, the pressure building at the base of his spine. The professor was screaming now, a continuous stream of filthy praise and encouragement.

“You feel that, boy? You feel how full I am? You’re splitting me open!Good! Do it! Come in my ass!Flood me! Mark this magic while you still can!”

Her words tipped him over the edge. With a final, guttural roar, Chris slammed in as deep as he could go and erupted. Hot, thick pulses of his come shot deep into her channel, mixing with the slick oil, a savage claim against the cool glass. The orgasm ripped through him, violent and total, blurring his vision.

As he spent himself, the professor’s own climax hit. Her inner muscles clenched in a powerful, rippling series of contractions around his cock and the plug, milking him dry. Her shriek was pure, unadulterated triumph. The glowing colors in the plug flashed once, blindingly bright, and then went dark, becoming inert, clear glass.

A sudden silence fell, broken only by their ragged panting.

Then, the change.

It was like watching a time-lapse decay. The professor’s lush, round ass, still impaled, seemed to deflate slightly under Chris’s hands. The glowing, dusky gold of her skin paled, settling back into the more familiar, though still elegant, complexion of the older woman. The luxurious dark hair shortened and gained its familiar silver streaks. The overwhelming succubus aura dissipated, leaving the scent of sex, oil, and old books.

Professor Blackwood stood up, pushing Chris’s spent, softening cock from her ass with a soft, wet pop. She reached back and, with a slight wince, pulled the now-clear glass plug free. She placed it gently on the desk beside the empty oil bottle. When she turned to face them, she was herself again—sharp-featured, silver-haired, wrapped in a dark robe she’d gathered from a chair. Only a faint, satisfied flush on her cheeks and a dark, knowing glint in her eyes remained of the creature she had been.

Chris collapsed back onto his heels, his body trembling with exhaustion. Bea hurried to his side, her own transformation still in full, pin-up glory, her face a mask of dazed wonder. She still held the jar of candies clutched to her chest.

“A most satisfactory gratuity,” the professor said, her voice now its usual, cultured tenor, though slightly hoarse. She looked at the jar in Bea’s hands. “A dozen should suffice. For… holiday recreation. My treat. Now, I suggest you two get dressed. The mundane world awaits.”

She smiled then, a real smile that crinkled the corners of her eyes. “And do remember, my dears… the magic always fades. But the memory… and the appetite it awakens… those are entirely up to you.”
