Chapter 16: Double Penetration Revelation
The silence that followed was not quiet. It was filled with the ragged symphony of their breathing, the drip of fluids on linoleum, and the low, contented hum that emanated from Ellie’s core. Mark leaned against a shelf, his trousers around his ankles, staring at the woman he thought he knew as she slowly straightened up from the table. She moved with a new, unsettling grace, a predator’s economy. The mess between her legs was profound, a glistening testament to the violation, but she seemed utterly unashamed.
“Jesus, Ellie,” Mark breathed, the words trembling out of him. He was pale, shaken, exhilarated, horrified. His glasses were fogged. “What… what was that?”
“That was a start,” she said, her voice steady, deep. She turned to face him, and in the flickering fluorescence, he saw it. The soft cotton of her t-shirt was straining across her chest. The curves he’d always found sweetly modest were fuller, rounder, the tips of her breasts pressing against the fabric with a pronounced, hard outline. It was subtle, but undeniable. She was changing.
Before he could form another question, a fresh, aggressive vibration tore through her. It wasn’t sated. It was hungry again, impatient. The hum escalated into a snarl that made her teeth click together.
Her eyes, dark and dilated, locked onto his. He was still hard. Shock and arousal were a potent cocktail, and his cock, slick with her and him, stood defiantly between them.
“It’s not finished,” she growled.
In one fluid, powerful motion, she closed the distance and shoved him backwards. He stumbled, off-balance, and landed hard on his back atop the wooden table they’d just defiled. Catalogues crunched beneath him. Before he could even process the fall, she was on him.
Before he could even process the fall, she was on him. Her hands pinned his wrists to the rough wood, her weight a delicious, shocking anchor. “Don’t move,” she commanded, her breath hot against his throat.
Then she shifted, raising her hips with a practiced ease. He felt the swollen head of his cock press against her asshole.
“Ellie, wait—” he gasped.
She didn’t. She dropped her full weight down, sheathing him in a single, brutal stroke. His world dissolved into a white-hot tunnel of pressure as her ass consumed him, the resistance giving way to a slick, scorching heat. He cried out, a raw sound torn from his chest.
“Fuck,” she grunted, her own voice strangled. “Oh, fuck, that’s it.”
She began to move, riding him with a rough, piston-like rhythm that made the table legs screech against the floor. Each downward plunge was a claim. Mark could only gasp, his head thrown back, his fingers scrabbling against the wood. Beneath the brutal grip of her ass, he felt it—a deep, invasive thrumming, a powerful mechanical purr that originated from her core and vibrated through the shared wall of flesh into his own buried cock.
The Hummingbird was alive inside her, and it was growing.
Ellie’s moans became choked, ecstatic sobs. “It’s… growing,” she panted, her rhythm faltering for a second as a wave of intense sensation racked her. “Can you feel it? Pushing against you?”
He could. A distinct, firm pressure began to mass against the upper wall of her channel, bearing down on his cock trapped in her ass. It wasn't painful; it was a constant, insistent fullness that amplified every drag and thrust. The dual stimulation was maddening—the tight, gripping clutch of her rectum and this phantom, vibrating bulk crowding him from the other side.
“Jesus Christ,” he whispered, watching her face contort in pleasure. He was a passenger in this, utterly passive, witnessing her transformation in real time. Her chest heaved, and the fabric of her shirt stretched tauter, the swell of her breasts more pronounced, their nipples hard pebbles against the cotton. Lower, where her thighs met, the flushed, ruddy length of her cockette—that new, impossible part of her—stirred and thickened, gaining a palpable inch as he watched, dumbstruck.
“It feels so full,” she groaned, arching her back, her pace becoming erratic, desperate. “I’m so fucking full of both of you.” The hum intensified, becoming a tangible force in the room, shaking the old paperbacks on their shelves. Drool slipped from the corner of her mouth as she fucked herself on him, impaling her ass on his dick while the thing in her pussy molded her from within, stretching her limits, reshaping her.
She leaned forward, her enlarged breasts brushing his chest, and grabbed his face. “Look at me,” she snarled, her eyes wild, pupil-less pools. “Watch what it’s doing to me. Watch what you’re doing to me.”
He was locked in her gaze, feeling her internal muscles clamp and release around him in time with the Hummingbird’s pulses. The pressure from the other side grew steadily, a relentless expansion that made her inner walls feel impossibly thin, a mere membrane separating his cock from the artifact’s throbbing bulk. Her cockette, now nearly four inches, brushed against his stomach with each of her thrusts, leaving wet, hot smears.
A low, guttural sound built in her throat, a promise of ruin. The fluorescent light buzzed overhead in sympathy with the deeper vibration consuming her body. Mark knew, with a certainty that chilled his blood even as his hips jerked upward to meet her, that this was just another beginning.
Her hips stuttered against him, losing all rhythm, consumed by something primal and mounting. The Hummingbird’s vibration wasn’t a hum anymore. It was a roar, a sub-audible frequency that rattled their bones and made the dust motes dance in the slanted light.
“Oh god, oh fuck, I’m—” Her words dissolved into a shattered cry.
It wasn’t just an orgasm. It was an expulsion. Her back arched impossibly, every muscle corded tight as a bowstring. Inside, her cunt clamped in violent, milking spasms around the throbbing artifact, while her ass squeezed his cock in a relentless, pulsing vice.
From the flushed, ruddy tip of her cockette, a thick, pearlescent jet arced through the air. It wasn't a weak dribble or a few spurts. It was a hot, voluminous rope that slapped wetly across Mark’s sternum with a sound like a damp towel hitting concrete. A second followed, and a third, painting his chest and stomach in streaking, opalescent lines that steamed in the cool air of the back room.
The force of it surprised her, a gut-deep convulsion that left her trembling. She looked down, panting, watching the last few drops bead and fall onto the mess she’d made of him.
Mark stared at the fluid cooling on his skin. His cock, still buried in her tight, quivering heat, gave a hard, sympathetic twitch. A slow, dazed grin spread across his face, cutting through the shock and the confusion.
“Hell,” he breathed, his voice ragged with awe. “That’s… Jesus, Ellie. That’s the hottest thing I’ve ever seen.”
He reached a trembling hand to his chest, swiping two fingers through the sticky spill. He brought them to his lips, his eyes locked on hers, and tasted. His expression shifted, deepened. “Fuck.”
A profound, shuddering sigh escaped Ellie. The violent tension bled from her shoulders, replaced by a liquid, boneless satisfaction. The Hummingbird’s furious roar diminished, dialing back to its original, contented purr, a gentle thrumming nestled deep within her transformed flesh. It felt sated. For now.
She slumped forward, catching herself on her hands above him, her auburn hair curtaining their faces. Her new weight settled fully onto him, a soft, heavy warmth. She nuzzled into the crook of his neck, breathing in the scent of sweat, sex, and old paper.
“Told you,” she murmured, her voice husky and spent. “Just a start.”
They lay there on the table, sticky and shattered, as the fluorescent light buzzed a steady, mundane song overhead.
