Chapter 42: Succubus
The silence that followed was thick and strange, broken only by the ragged symphony of their breathing. Ellie’s massive cock, now slick and glistening with a mix of their fluids, began to soften. It wasn’t a sudden deflation, but a slow, weary retreat. The impossible rigidity melted away, the throbbing veins subsiding, and the terrifying length shortened, pulling back from the deepest, transformed pocket inside Cassandra.
With a final, wet shlup, it slipped free, flopping heavily against Ellie’s thigh—still impressively large, but human again, or close to it. A river of thick, white cum followed, leaking from Cassandra’s stretched entrance and pooling on the sheets between Ellie’s legs. The air in the room, already saturated, now carried the heavy, salty tang of spent sex.
Cassandra collapsed onto her side, her body shuddering. She felt hollowed out and profoundly full at the same time. Her cunt, gaping slightly, felt cool air touch internal spaces that had never known it. She pressed her thighs together, a feeble attempt to contain the slow, warm trickle. “Fucking hell,” she breathed, the words scraping her raw throat.
On the floor, Mona whimpered. The five cocks lay across her pelvis and thighs, semi-flaccid and gleaming, looking like a nest of strange, sleeping eels. The Hummingbird was still buried within her, its obsidian surface pulsing with a slow, dark light.
Ellie stared at it, her mind clearing like fog burning off a lake. The blue glow had left her eyes. Her new breasts, heavy and sensitive, ached with every heartbeat. The memory of the power, of the sheer size of what she’d been, throbbed in her like a phantom limb. It was terrifying and addictive.
Cassandra propped herself up on an elbow, her gaze fixed on the toy nestled in Mona’s folds. Curiosity, sharp and pragmatic, cut through her post-coital haze. “That thing,” she said, her voice low. “It did all this.”
“It feels… content,” Mona murmured, her eyes closed. Her hand drifted down to rest near the base of the carved artifact, not touching, just hovering. “Warm.”
Cassandra swung her legs off the bed, wincing as her transformed muscles protested. She knelt on the rug beside Mona, heedless of the cooling puddles of cum. “Let’s see it.”
Ellie watched, a knot of anxiety tightening in her stomach. “Cass, maybe don’t—”
But Cassandra had already reached out. Her fingers, delicate but sure, closed around the exposed end of The Hummingbird. It was warmer than skin, humming faintly against her palm. She gave an experimental tug.
It didn’t budge.
It wasn’t stuck; it was resistant. A low, warning thrum traveled up her arm.
Mona’s eyes flew open. “Oh,” she gasped. Her back arched slightly off the floor.
Cassandra frowned, her competitive nature sparked. She tightened her grip, bracing her other hand on Mona’s hip. “Come on, you little bastard. Let go.”
She pulled harder.
The Hummingbird’s hum pitched upward. The dark light flared.
And Mona’s five cocks twitched. A unified, sluggish jerk. Then, as Cassandra tugged again, they began to stiffen. Not with sexual arousal, but with a reactive, defensive inflation. They grew thicker, the veins rising like cords under the skin. A bead of clear pre-cum welled at each tip.
“Cassandra, stop,” Mona moaned, but it was a moan of overwhelmed sensation, not a command.
“It’s reacting to you,” Ellie said, pushing herself up to watch. Her own spent cock gave a sympathetic, faint throb.
“I see that,” Cassandra gritted out, her fascination now fully engaged. She didn’t release the toy. Instead, she pulled once more, a steady, insisting pressure.
The response was immediate. The five cocks surged, gaining another half-inch of girth and length, becoming fully, dauntingly erect once more. They swayed in the air, aimed at Cassandra’s face and chest. One tapped gently against her cheek, leaving a sticky smear.
A wild idea bloomed in Cassandra’s eyes. She released The Hummingbird and sat back on her heels, staring at the forest of flesh before her. “It doesn’t want to come out,” she said, mostly to herself. “It’s happy where it is. And it grows these… when it’s threatened.”
She looked from the cocks to Mona’s flushed, overwhelmed face, then to Ellie. A slow, dirty smile spread across her lips. “So if pulling on it makes them bigger…”
She didn’t finish the sentence. Instead, she leaned forward again. But this time, her target wasn’t The Hummingbird. She wrapped her hand around the nearest cock. It was hot and surprisingly heavy in her grasp, its skin like velvet over steel.
Mona cried out, a sharp, startled sound. “What are you—?”
“Testing a theory,” Cassandra murmured. She began to stroke, a firm, practiced motion from root to tip. The cock swelled fractionally in her hand, pulsing. Pre-cum seeped freely, coating her fingers.
The slickness made her grip slide, a filthy, intimate sound in the quiet room. She locked eyes with Mona, whose expression had shifted from overwhelmed to something like awed anticipation. “You like that, don’t you?” Cassandra purred, giving the shaft a firm, twisting pull.
She released the cock, letting it bob heavily in the air. Her gaze shifted to the carved, humming artifact still nestled deep in Mona’s folds. That knowing, dirty smile returned, wider now.
With deliberate slowness, she wrapped her fingers around The Hummingbird again. The carved surface vibrated against her palm, a warning tremor. Mona inhaled sharply, her hips lifting an inch from the floor.
“Cass, what are you doing?” Ellie asked, her voice a mix of fear and fascination from the bed.
“What it wants me to do,” Cassandra replied, her tone calm and certain.
She pulled.
It wasn’t a tentative tug this time. It was a strong, steady, insistent yank, as if trying to pry a stubborn cork from a bottle. The Hummingbird resisted, its thrum deepening to a defensive growl that vibrated up Cassandra’s arm.
Mona’s whole body seized. A choked scream escaped her lips, not of pain, but of unbearable, electrifying stimulation. The cock Cassandra had just been stroking gave a violent jerk.
Then it grew.
It swelled in diameter, thickening in Cassandra’s peripheral vision, the veins rising like ropes. It added two inches of length, then three, curving upward with a newfound, intimidating weight. The other four cocks followed suit, a grotesque chorus of expanding flesh, each one surging outward in a synchronized wave of growth.
“Fuck yes,” Cassandra hissed, her pleasure purely in the power of it. She maintained her pull on The Hummingbird, not yanking now but holding firm, applying constant pressure.
The growth didn’t stop. The five members thickened further, each one now as large around as a wine bottle, their lengths surpassing eighteen inches. They were matching the monstrous size Ellie’s cock had been at its peak. But the one directly in front of Cassandra, the one her earlier attention had seemingly primed, surged ahead.
It became substantially larger.
It dwarfed the others, a truly inhuman pillar of flesh that now strained toward twenty-five inches, its head swelling to a broad, dripping plum. The sheer mass of it was dizzying, a flushed, veined obelisk that cast a shadow across Mona’s trembling stomach. Pre-cum now flowed from its slit in a steady, thin stream, pattering onto her skin.
Cassandra released The Hummingbird, sitting back to admire her work. She was flushed, her breath quick. “Look at that,” she whispered, her voice full of dark wonder. “Just look at what you made.”
Mona could only stare, her eyes wide with a terror that was inextricably woven with deep, shocking arousal. The weight of the cocks was immense, a painful, glorious pressure. The largest one, the behemoth, lay heavily across her chest, its tip nudging her chin.
Ellie watched from the bed, her own body humming with a sympathetic echo. She understood the addictiveness of this power, the horrifying allure of controlling such raw transformation. Cassandra reached out, not for The Hummingbird this time, but to wrap both hands around the base of the monstrous, dominant cock.
Her fingers didn’t meet.
