Chapter 11: The Growing Engine
The grey dawn light did nothing to soften the room. It just made the mess look tired. Stale perfume, drying sweat, the sweet-metallic tang of transformation hanging in the air like a ghost.
Ronnie was the first to feel it.
She was lying on her side, one hand absently kneading the plush, cum-heavy swell of her own belly, the other still draped over Mae’s shaft where it lay between them. The skin under her palm twitched.
Not a pulse. A spasm.
“Uh,” Ronnie said, frowning. She opened her eyes. “You guys feel that?”
Bree, propped against the headboard with her new, finger-like teats resting on the vast shelf of her breasts, glanced down. Skye was already half-asleep, her new cock soft against her thigh.
Mae jerked again. This time, it was a visible ripple under the slick skin, a wave of tension that traveled from the broad base up to the flared head.
Then she began to grow.
It wasn’t subtle. It was an invasion of space. The thick shaft, already intimidating, tightened and expanded, pushing Ronnie’s hand away by sheer force. The veins on the surface grew more pronounced, rising like cables under a rubbery sheath. The flesh darkened, taking on a flushed, angry hue.
“Holy shit,” Skye whispered, pushing herself up on her elbows, sleep forgotten. “Look at it.”
Mae lengthened. An inch. Then two. The tip, bulbous and spongy, pushed against Bree’s ankle where she sat. She didn’t move it. She watched, her analytical mind fully offline, replaced by pure, hungry wonder.
The growth accelerated. With a soft, wet sound of stretching tissue, Mae’s shaft pushed past three feet in length, curving slightly under its own new weight. The base thickened, becoming as wide as a forearm, the skin straining.
Beneath, the scrotum—once a modest pair of orbs—swelled. They plumped, filling out like balloons being filled from some internal, inexhaustible tap. They grew to the size of softballs, then cantaloupes, their skin pulled taut and shiny, a network of blue veins surfacing like a map of subterranean rivers. Finally, they settled, heavy and ponderous, each one the size of a basketball, resting on the ruined silk with a palpable, fleshy weight.
The room was dead silent save for the ragged breathing of the three women. Mae, now a monstrous, three-foot-long behemoth, pulsed with a slow, alien rhythm. Heat radiated from her in waves.
Ronnie let out a low, shuddering breath. “Fuck. Me.” She was still stuffed, still leaking from her own session, but the sight triggered a fresh, deep throb inside her. “It’s… it’s beautiful.”
Bree finally moved. She slid off the bed, her own transformed body moving with a new, heavy grace. She stood over Mae, looking down at the colossal thing. A tool. A weapon. A god.
“The growth is a direct correlation to usage,” she murmured, but the clinical tone was gone. It was reverence. “Our hunger is the feedstock. Our changes are the product. And this…” She reached out, her fingers tracing the steaming, veined length. “This is the factory.”
Skye’s eyes were locked on the massive, horse cock. A hungry smile played on her lips. She licked them. “I bet my fans would lose their absolute minds.” She looked at Bree. “But first… I wanna know what it feels like. Everywhere.”
Bree understood. She nodded, her teats swaying. She bent, her movements deliberate, and wrapped her hand around Mae’s tip. It was almost too large to grasp. The skin was burning hot, softer than silk.
“Ronnie,” Bree said, her voice calm. “Hold her steady. At the base.”
Ronnie scrambled to obey, her hands gripping the immense girth near the root, her fingers not meeting. She grinned, the strain in her arms exciting her. “Got her.”
Bree turned to Skye, who was already shifting, pushing herself up to her knees on the mattress, her own massive breasts swinging heavily beneath her. She opened her mouth, tilting her head back, an unmistakable invitation.
“Let’s see how much she can take,” Bree whispered, and guided the broad, slick head toward Skye’s lips.
Skye took it. The flared crown pushed past her lips, stretching them wide. She gagged instantly, her eyes watering, but she pushed forward, forcing her jaw wider. It was a brutal, slow intrusion. The head filled her mouth completely, pressing her tongue flat, then began the inexorable slide down her throat.
Her neck distended. A visible bulge traveled down it, a lump of living flesh forcing its way into her esophagus. Skye’s eyes rolled back, a muffled, wet sound escaping her around the shaft. Her hands came up, not to push it away, but to clutch at the length, encouraging it.
Bree fed her more. Inch after impossible inch, until over a foot of the monstrous thing was buried in Skye’s gullet. Skye’s face was flushed purple, tears streaming down her cheeks, but her own newly-made cock was rigid, twitching, a bead of clear pre-cum welling at the tip.
Ronnie watched, mesmerized, her own body aching. “She’s gonna pop.”
Then, deep within Mae, the pressure hit its peak.
It wasn’t an orgasm. It was a geyser.
Mae’s colossal balls tightened, drawing up, and a torrent of cum erupted from the tip buried in Skye’s throat. It wasn’t spurts. It was a continuous, hot flood, pumped directly into Skye’s stomach with violent force.
Skye’s eyes flew open, wide with shock and pleasure. A guttural, drowned scream vibrated around the shaft. Her belly, previously soft, began to distend. It rounded outward, tightening the skin, swelling under the direct, internal deluge. It looked like she’d swallowed a bowling ball, then a melon, the curve becoming pronounced, taut, and glossy.
At the same time, her own cock jerked violently, shooting ribbons of cum across the rumpled sheets in helpless, sympathetic spasms.
The sound in the room was obscene—the wet, gulping pump of Mae’s release, the choked, pleasured sounds from Skye, the ragged panting from Ronnie and Bree as they watched.
The flood seemed endless. It filled Skye until she looked several months pregnant, her swollen belly firm and heavy. Finally, with a final, shuddering pulse, Mae’s release trickled to a stop.
Bree pulled, slowly, extracting the slick, dripping length from Skye’s ravaged throat. Skye collapsed forward onto her hands, gasping, strings of saliva and cum connecting her lips to the tip. She coughed, a wet, hacking sound, and rubbed her rounded stomach with a look of bewildered ecstasy.
“Tastes… different,” she rasped, her voice shredded. “Spicy. Like ozone and… and want.”
Mae, emptied again, lay between them. But the growth hadn’t stopped. If anything, the violent expulsion seemed to have fueled it further. The shaft twitched, and with a low, fibrous creaking sound, it gained another two inches in length, the skin at the base stretching tighter around Ronnie’s straining hands.
“It’s not slowing down,” Ronnie said, a note of genuine awe—and the first thread of fear—in her voice. “We keep feeding it. It keeps growing. What happens when…”
She didn’t finish. The implication hung in the scented air, heavier than the silence.
Bree looked from the monstrous, still-swelling form of Mae, to Skye’s cum-filled belly, to Ronnie’s cum-plumped curves, and finally down at her own hermaphroditic glory. A perfect, closed loop. A system with no off switch.
On the bed, Skye began to laugh, a hoarse, broken sound. She rolled onto her back, cradling her swollen stomach, her other hand wrapping around her own growing cock again. "FUCK I shouldn't have swallowed all Mae's cum. I'm growing to grow huge!" “They’re gonna love this,” she whispered to the ceiling, already scripting her next broadcast in her head. “They’re gonna fucking love it.”
And deep within the dark, silent core of the growing, pulsating monolith that was her prison, Mae felt it all. The stretching. The filling. The raw, desperate hunger that flowed into her and fueled this endless, terrifying expansion. She was a universe of sensation with no control, a god of flesh with no voice. Her only thought was a silent, endless scream that vibrated in time with her own, ever-quickening, monstrous pulse.
Skye continues growing. Her cock might be the size of her body when it stops growing...
