Chapter 4 by Captain Edison Captain Edison

What does Traps do now that Dr. Vex is dead?

Embrace the Power

The lab reeked of sex, chemicals, and victory.

Dr. Vex’s corpse lay at your feet, skull caved in. Velocity Vixen was still strapped to the table, breasts massively swollen and leaking glowing pink fluid, hips and ass obscenely widened, her pussy hugely puffy and dripping.

She was starting to wake up, eyes fluttering in panic.

You placed your glowing fingertips against her temple and pushed. The stolen mutagenic power surged clumsily. A mild headache bloomed behind your eyes, but it was manageable. Vixen’s eyes widened for a split second, then rolled back as her body went limp. She let out one soft, defeated moan before sinking into a deep, chemically-induced sleep.

You smiled darkly.

It was easier than you expected.

You unstrapped her and carried her glistening, hyper-curvy body across the lab. An empty glass cage stood waiting. You slid her inside, arranging her so her massive leaking breasts pressed against the transparent wall, thick thighs spread, swollen pussy fully on display. The door hissed shut and locked with a satisfying click.

Only then did you notice the golden goggles sitting on the side table.

Curious, you picked them up and slid them over your eyes.

You're surprised when a neural interface hummed to life instantly, blue holographic overlays flooding your vision. Curious, you focused on a nearby vial.

You turned your gaze to the glass cage containing Velocity Vixen.

A detailed prompt appeared, floating gently above her sleeping, naked form:

You spent the next twenty minutes slowly circling her cage, goggles feeding you constant streams of data. You could see potential changes hovering like ghostly previews — options to balloon her breasts even larger, add multiple rows of nipples, turn her skin latex-smooth, increase her lactation output, or deepen her arousal until she begged for use. The goggles even estimated “mutagen cost” and risk levels for each change.

The power was intoxicating.

You could make her perfect. Or you could make her yours.

Satisfied for now, you dragged Vex’s body up the rain-slick stairs and dumped him into the churning river behind the facility. Then you returned and spent several more hours devouring his files.

The man had been planning something massive. He wasn’t just transforming heroines for fun — he was building an army of obedient, hyper-fertile superslaves to gift to the Iron Dominion’s elite. Overlord Kane, his secret patron, had already commissioned three custom girls and was waiting for the next delivery. Vex’s endgame was clear: prove his worth, earn a seat among the Overlords, and eventually surpass them using stolen powers and his growing collection.

Now all of it belonged to you.

A loud bang echoed through the lab.

Velocity Vixen was awake.

She slammed her fists against the thick glass, naked, furious, and still heavily modified. Her breasts had continued to slowly expand even while **** — now even larger, heavy, and constantly leaking. Her hips and ass were pure breeding material, and her swollen pussy visibly throbbed against the glass.

“You fucking bastard!” she screamed, voice slightly muffled. “Let me out of here right now! I’ll kill you for this! When I get out I’m going to rip your—”

You stood up slowly, hands clasped behind your back, and walked over to her cage with a calm, predatory smile.

Vixen faltered for a moment, seeing the look on your face. Then she snarled and punched the glass again.

You reached down and flipped the switch beneath her cage.

Pink mist immediately began pouring in from the vents. Vixen’s eyes widened in horror as the sweet, narcotic gas rapidly filled the enclosure.

“No— wait— don’t you dare—!”

You leaned in close to the glass, voice low and steady.

“You’re going to help me take over the Iron Dominion.”

Her eyes widened in shock and dawning terror as the pink mist thickened. Her movements slowed. Her massive breasts heaved, nipples leaking faster. Her swollen pussy twitched visibly. The fight drained from her face, replaced by glassy, needy arousal.

Before the mindless trance fully claimed her, you saw one last flicker of defiance in her eyes… and something darker. Something hungry.

The other two women in their cages moaned softly in approval, welcoming their new sister.

You were no longer a henchman.

You were the new master of this lab.

And Velocity Vixen was going to be your first true masterpiece.

How do you begin building your empire?
