More, More, MORE!

Carly brought her stinger to bear, moving to stand over the dazed young futa. She turned the girl over on her back and delivered a hefty sting to each of Jenny's newly formed testicles.

The young woman arched her back and let out a deep scream as balls pulsated.

Carly watched in fascination as the girl's walnuts suddenly swelled to oranges, their color darkening to a deep purple. Filled with Corruption.

Glowing red veins started to radiate out of Jenny's demonic testes, snaking up her considerable penis like vines. Carly knew she had lit the fire.

The balls, the core of Jenny's essence now, we're not merely filled with Carly's darkness but reproducing it.

Jenny's cock, already large, started to swell larger in her hands. It quickly developed into an inhuman size, nearly a foot and a half in length and almost as thick as a small log. Bumps and ridges started to erupt from the surface.

Meanwhile, the evil was spreading up Jenny's body, remaking her. The girl's legs lengthened and filled with powerful muscle, putting her well over six feet. Her arms and midsection hardened and swelled with muscular power as well.

Jenny's eyes started to glow a baleful red as fangs emerged from her mouth.

With a deep roar, the monster that had once been Jenny busted another load, rocketing nearly a gallon of cum across the grass. It was now pitch black.

Jenny stood, her head swimming with vile thoughts. On the ground in front of her was her best friend. So sweet and supple.

She felt like a wild animal. She needed to breed. She needed more.
