A little boost of speed... and power?

Vixen’s **** whisper cut through the chaos.

“Change me. Whatever you need to do — do it now!”

You grabbed her shoulders, the golden goggles flaring as you poured raw mutagenic power into her. You focused first on restoring her speed. Blue electric sparks exploded across her skin. Vixen gasped sharply, then blurred out of the closet in a streak of crimson and black.

But your mind was racing with adrenaline. In that split second of panic, an intrusive fantasy flashed through you — Make her as strong as Titanus. Big. Powerful. Unstoppable.

You hadn’t meant to push it that far.

Vixen reappeared beside Seraphine in a burst of speed, grabbing for the Overlord. The fight exploded.

Seraphine was no easy prey. She twisted gracefully, her voice ringing out as she created multiple illusory copies of herself. Vixen blurred between them, landing solid hits on one only for it to shimmer and vanish. Seraphine laughed, launching a powerful kick that sent Vixen skidding back.

“You’re fast, little speedster,” Seraphine taunted, “but you’re predictable.”

Vixen growled and charged again — but as she did, her body began to change.

It started in her shoulders. They broadened with a deep, wet crack, muscle swelling rapidly under her skin. Vixen grunted in shock as her arms thickened, biceps and forearms ballooning with raw power. Her thighs exploded outward, tearing slightly at the seams of her pants as dense, powerful muscle formed. Her height shot up several inches in seconds.

“Fuck— what’s happening to me?!” she snarled, voice already dropping into a huskier register.

The fight turned brutal. Vixen’s growing strength allowed her to land heavier blows, cracking the walls, but Seraphine’s illusions and flight kept her just out of reach, landing stinging counters that left Vixen snarling in frustration.

You quickly disabled the trap holding Titanus and set a new “pause portal” field a few feet ahead of the fighting women.

“Vixen! Push her toward me!” you shouted.

Vixen roared, grabbed the real Seraphine mid-flight, and hurled her forward with everything she had. Seraphine flew straight into your trap.

The pause portal activated with a shimmering ripple. Seraphine froze mid-air, body locked in place, eyes wide with fury and confusion.

It worked! You and Titanus share a quick high-five in celebration before a groan from Vixen brings your attention back to her.

She staggered, bending over with a deep, pained groan. Her hands clutched her crotch as something massive shifted violently beneath her clothes. The fabric of her pants bulged obscenely. A thick, heavy cock rapidly grew between her legs, thickening and lengthening pulse by pulse, veins standing out, until it strained painfully against the material. Heavy balls swelled beneath it, churning visibly.

“Oh god— Traps—!” she gasped, voice cracking between feminine and deep masculine tones. Her new cock twitched hard, leaking precum that soaked through her pants as the transformation locked in.

Titanus, now free, rushed over with you. When you helped Vixen up, the resemblance was unmistakable — she looked like a taller, slightly more feminine version of Titanus, powerfully muscled, broad-shouldered, with a massive erection tenting her ruined pants.

Titanus stared, eyes wide. “Vix…? You look… you look like me. Only with… extra equipment.”

Vixen looked down at herself in horrified fascination, one hand instinctively gripping her new throbbing cock through her clothes, breathing ragged.

“Traps…” she growled, voice deep and rough, cheeks burning with shame and unwanted arousal, “what the fuck did you do to me…?”
