Chapter 40: Ellie's Turn
Cassandra wiped her mouth on the back of her hand, her breathing still ragged. The taste of Mona – salt, copper, something else sweetly alien – clung to the back of her throat. She looked from the astonishing, softening tangle of flesh on Mona’s belly to Ellie, who was kneeling a few feet away, one hand wrapped loosely around the base of her own erection.
Ellie’s cock stood thick and proud, eight inches of flushed, veined flesh that seemed to pulse in time with the low hum still emanating from the toy buried inside Mona. It was a stark, simple line compared to Mona’s florid excess.
“You’re still hard,” Cassandra observed, her voice raspy. She pushed herself up from the floor, her movements unsteady. The front of her tank top was soaked, a damp patch spreading from her throat down between her breasts.
“It… doesn’t really go down,” Ellie said, her own voice thin with awe and residual shock. “Not completely. Not since…”
A fierce, predatory grin spread across Cassandra's face. She crawled over the rumpled rug, her eyes locked on Ellie’s cock. “Good.”
Mona groaned softly from her spot on the floor, a sound of sated exhaustion. The Hummingbird’s hum had subsided to a contented purr, and her extra cocks were rapidly receding, melting back into her body like wax held to a flame. They left behind only a swollen, heavily-used looking mound and the still-present base of the toy.
Cassandra ignored her. All her attention was on Ellie now. She knelt before her, the salt lamp painting her red hair a deep crimson. She looked up at Ellie, her gaze traveling from the shy, uncertain eyes to the full, heavy breasts straining against Ellie’s simple bra, down to the rigid proof of her transformation.
“Such a pretty dick for a pretty librarian,” Cassandra murmured, more to herself. She leaned forward, her lips parting.
But she didn’t take it in her mouth. Instead, she pressed her face against the side of it, nuzzling the hot, smooth skin. She breathed in Ellie’s scent – musk, clean sweat, the faint, permanent hint of lavender that seemed baked into Ellie’s skin. Then, with a deliberate slowness, Cassandra sat back on her heels and pulled her damp tank top over her head.
Her breasts were large, heavy, and pale in the dim light. Her nipples were already pebbled hard, dark rose against the white skin.
“Watch,” Cassandra commanded, her voice dropping to a low, conspiratorial register.
She took Ellie’s cock in one hand, guiding it firmly. With her other hand, she lifted the full weight of her left breast, squeezing the soft flesh around the shaft. The heat was intense. Ellie gasped, her hips twitching forward involuntarily.
Cassandra lifted her right breast, creating a deep, soft valley of cleavage. She pressed them together, encasing Ellie’s cock in a hot, slick prison of flesh.
“Oh, god,” Ellie whimpered. The sensation was utterly new. The soft, yielding pressure was everywhere, a constant, milking embrace that felt nothing like a hand or a mouth. It was overwhelming.
Cassandra began to move. She didn’t bob her head; she moved her whole upper body, sliding her breasts up and down Ellie’s length in a smooth, practiced rhythm. Her skin was still damp with sweat, creating a perfect, slippery friction. Each upward motion brought the firm peaks of her nipples dragging along the underside of Ellie’s cock, each downward stroke squeezed the head tightly between her breasts.
“Fuck, Cass,” Ellie moaned, her hands flying out to brace herself on the floor behind her. Her head lolled back, exposing the long line of her throat. Her new cock, already intensely sensitive, felt like a live wire.
“Yeah, you like that?” Cassandra grunted, increasing her pace. Her breasts jiggled with the motion, a mesmerizing, full-bodied undulation. “You like getting your little librarian cock all nice and wet between my tits?”
Ellie could only nod, words failing her. The building tension in her groin was swift and ruthless. It coiled deep in her abdomen, a hot, tight spring. Her balls, though absent, ached with a phantom need to release.
“You’re gonna come,” Cassandra stated, matter-of-fact. She leaned forward, her breath hot on Ellie’s stomach, and increased the pressure, squeezing her breasts tighter. The visual was obscene and breathtaking: the flushed, purple head of Ellie’s cock appearing and disappearing between the pale orbs, slick with moisture.
The spring snapped.
Ellie’s orgasm crashed into her with the force of a wave. It was shorter, sharper than the soul-wrenching releases The Hummingbird gave her, but no less intense for its focus. A raw, punched-out sound escaped her lips. Her hips bucked up, fucking the hot channel of Cassandra’s cleavage. Thick, pearly ropes of cum shot out, the first stripe hitting Cassandra’s chin, the next splattering across her collarbone and the upper slopes of her breasts.
Cassandra didn’t stop. She kept moving, slowing her rhythm but maintaining the pressure, milking Ellie through every last spasm. “There it is,” she cooed, her voice rough. “Look at you. Marking me up.”
Ellie shuddered, spent, her body going limp. But her cock, glistening with her own release and smeared between Cassandra’s tits, remained defiantly, fully hard.
Cassandra smiled, a slow, knowing curl of her lips. She released her breasts and sat back, swiping a finger through the cum on her skin and bringing it to her mouth. She sucked it clean, her eyes never leaving Ellie’s. “Still rock hard. Fucking perfect.”
With a sudden, decisive movement, Cassandra pushed Ellie backwards. Ellie fell onto her back with a soft thump, the air leaving her lungs in a rush. Before she could process it, Cassandra was straddling her hips, her knees sinking into the rug on either side of Ellie’s thighs.
Cassandra looked down at her, a queen surveying her territory. Her red hair formed a curtain around their faces. The smell of sex and ozone was overwhelming.
“Mona told me,” Cassandra said, her voice low and direct. “She said you don’t need to be touching it anymore. The toy. She said you can… make this happen.” She reached down and wrapped her fingers around Ellie’s slick cock, giving it a firm, possessive stroke. “Just by thinking it.”
Ellie’s breath hitched. It was true. In the days of transformation, in the quiet, stolen moments alone with The Hummingbird, she’d felt a new awareness growing in her mind—a faint, whispering control over the changes in her own body. She’d made her nipples hypersensitive once, just by wanting it. She’d coaxed her cock to a fuller hardness without touch. She hadn’t dared to try for more.
“I… I don’t know,” Ellie whispered.
From the floor, Mona made a weak sound of confirmation. “She can,” Mona breathed, her eyes closed. “I saw her do it.”
As if on cue, The Hummingbird, still nestled deep within Mona, emitted a low, resonant pulse. The hum wasn’t just sound; it was a physical vibration in the air, in the floorboards, in their bones.
In response, Ellie’s cock gave a violent, involuntary jump in Cassandra’s grip. It thickened, just a fraction, the veins along its length becoming more pronounced.
Cassandra’s eyes widened, then gleamed with avaricious delight. “There it is,” she hissed. “Do it, Ellie. I want to feel it.”
Ellie’s mind raced. The power was there, a dark, warm current at the base of her skull. It was seductive. It was terrifying. To use it willingly, not as a passive receiver but as an active participant…
“Make it bigger,” Cassandra commanded, lowering herself. The warm, soaked folds of her cunt hovered over the tip of Ellie’s cock. The anticipation was a physical ache. “Just a little. Fill me up.”
Ellie closed her eyes. She let go of the fear, the librarian’s instinct for order. She reached for the current. She didn’t push a command. She simply opened a door in her mind and invited.
It happened faster than she expected.
A surge of pure, electric heat flooded down her spine and gathered in her groin. Her cock spasmed in Cassandra’s hand, then began to swell. It wasn’t a gentle growth. It was an assertion. The shaft expanded, gaining girth, the head flaring wider. Ellie felt a stretching, burning sensation that quickly melted into a profound, aching fullness.
“Fuck yes,” Cassandra groaned, watching the transformation inches from her face. “Just like that.”
Ellie’s cock grew from eight inches to a thick, imposing ten. Cassandra guided the swollen head to her entrance, slick with her own arousal. She didn’t slide onto it. She sank.
The stretch was immediate and immense. Cassandra threw her head back, a guttural cry tearing from her throat. “Oh, Christ,” she gasped. Her cunt strained to accommodate the new girth, clinging viscously to every inch as she impaled herself.
She bottomed out, Ellie’s newly enlarged cock buried to the hilt inside her. They both gasped, a synchronized sound of shock and pleasure. Cassandra’s internal muscles fluttered wildly around the invasion, a frantic, automatic response.
Cassandra braced her hands on Ellie’s stomach, her nails digging in. She began to move, rolling her hips in a slow, deep grind. “Good,” she panted, her eyes squeezed shut in concentration. “So fucking good. But don’t…” She paused, lifting herself almost all the way off before sinking down again with a wet slap. “…don’t get greedy. Don’t make it too big yet. I want to feel every fucking inch you give me.”
The command, and the searing friction of her movement, shattered Ellie’s control. The door in her mind blew wide open.
The Hummingbird in Mona pulsed again, a brighter, sharper hum. Ellie’s cock jumped once more inside Cassandra’s clutching heat.
It grew another inch.
Cassandra’s rhythm faltered. A look of pained ecstasy twisted her features. “Ellie… wait…”
But Ellie was lost. The feedback loop was too powerful: Cassandra’s tight, wet channel squeezing her, the intoxicating sense of her own body expanding to fill it, and the approving drone of The Hummingbird vibrating through the very air. She wasn’t just inviting the change now; she was demanding it.
Twelve inches. Thirteen.
“Stop,” Cassandra gasped, but her body betrayed her, her hips still rocking, her cunt dripping. The stretch was crossing from pleasure into a sharp, burning ache. “Too much, you’re too—”
Fourteen. Fifteen.
Cassandra screamed. It was a sound of pure, overwhelming sensation. She couldn’t lift off anymore. She was pinned, speared, stuffed fuller than she’d ever dreamed possible. Her eyes flew open, wide and desperate, staring into Ellie’s, which were now glowing with an internal, ozone-blue light.
From the floor, Mona began to laugh, a weak, delirious sound. The Hummingbird’s hum climbed to a fever pitch, a sound of triumph.
Ellie’s hands shot up, gripping Cassandra’s hips. She wasn’t guiding her anymore. She was holding her in place as her cock, now a monstrous sixteen-inch pillar of flesh, swelled to its final, terrifying size inside the woman riding her. The connection was complete. The power wasn’t just in her; it was flowing through her, from the toy, through her, into Cassandra, binding them all in a circuit of raw, transformative desire. And somewhere, in the back of her mind, Ellie knew this was just the beginning. This was just a signal, flaring into the night.
