Erin felt the venom flow through her veins like a raging fire, a burning heat that coursed through every inch of her body, making her feel as though she were on fire. She thrashed around violently as she felt her body shifting and changing, her limbs growing disproportionately to her body. Her muscles bulged and grew, her arms and legs grew thicker and stronger becoming larger than her entire body had been.
Erin groaned as she felt her body shifting once more, her torso shifting and growing longer and wider, her ass and thighs swelling up and becoming soft and plump as her breasts seemed to grow even larger. Her body continued to shift and change, her arms and legs becoming long and slender while her hands grew large and powerful. Her body was a blur of movement as she continued to writhe and squirm, her muscles rippling and bulging as she tried to contain the energy coursing through her veins.
Erin could feel the fire spread to her lower torso and legs. She could feel her body shifting and changing, her ass swelling and her thighs growing thicker. Her groin tingled with need as she felt her pussy growing wet and sensitive. She moaned and writhed, her body shifting and changing as she felt her new form coming to life. Her legs stretched and grew, becoming long and powerful, before they too changed. Erin felt a tugging sensation in her legs as they started to fuse together, forming a single limb. Her toes fused together, her feet and ankles merging into a single mass before elongating. Erin's body shuddered and quivered as she felt her new limb taking shape. She could feel the fire coursing through her veins as she felt her new tail slowly growing from the base of her spine.
Erin moaned and writhed as her tail stretched and grew, growing longer and thicker, dark blue scales shifting and spreading over her skin. She could feel her body shifting and changing as her scales spread over her flesh. Her body tingled as her tail grew thicker and heavier, her scales stretching and growing thicker as her tail took shape. Her tail was now longer than she was tall, her scales thick and heavy. She could feel her tail growing stronger and heavier, her muscles rippling and flexing as her tail continued to grow.
Erin moaned as her breasts swelled and grew, her nipples tingling and throbbing as her breasts became larger and softer, her scales shifting and engulfing her skin. She could feel her breasts swelling and growing, her nipples growing longer and thicker, her breasts swelling and growing until they were the size of basketballs.
Feeling her a throbbing and twitching in her torso, she looked down to see nubs growing below her arms. At first they looked like nothing more than bumps, but they soon grew longer and thicker, eventually taking the shape of a pair of short, stubby arms. She could feel the fire burning in her veins as her arms grew longer and thicker, her muscles growing and flexing as her arms stretched and grew. In a short while the arms became as large as her other ones, the skin stretching over her muscle as it grew thicker and stronger.
Her scalp tingled as her hair solidified, becoming a dark red cobra hood that flared out from her head. Her scalp and the back of her neck burned as her hood grew, stretching and growing until it reached her shoulders.
Erin panted in ecstasy as her changes slowed down, the effects of the venom finishing in her. Her eyes widened as she took in her new form. She was a massive cobra, just as large as Damien if not slightly larger. Damien watched her change with a satisfied smirk as he slithered towards her. She could feel his presence as he drew near. Her eyes were drawn to his cocks, both of them dripping precum as he drew closer.
