Robert could feel energy course through his body as soon as his face made contact with the mask. His eyes widened in terror as sleek black hair began to obscure his vision. He wriggled in an attempt to break free of Helen's grasp, but she simply stretched her arms around him again and tightened her grasp. His hair had reached his lower back when he had begun to shrink. Soon he was shorter than Helen. He could feel his muscle mass disappearing as his physique took on the form of a teenage girl. His arms grew slender as his shoulders cracked together. As the changes became more drastic, Helen retracted her arms and let Robert slump to the ground on all fours.
Robert looked up at Helen in desperation as his back cracked and gained a distinctly feminine arch. He moaned as he pushed his chest outwards and felt two modestly sized breasts stretch against his now loose clothing. His stomach became flat as his hips cracked outwards. Suddenly, he felt his clothes tighten as they morphed into a uniform similar to Helen's. He could feel his ass stretch the new material as it inflated. At the same time, he could feel his groin being pulled up into him. His crotch began to tingle as it changed, before suddenly exploding in an orgasmic sensation. He rolled onto his back as he quivered in pleasure.
He moaned as the suit pressed up against his tight new pussy, and he could hear his voice getting higher and higher, until it peaked as he orgasmed again. As the sensations subsided, he began to stand back up. He looked at himself in the mirror, then at Helen. Reluctantly, he watched his face turn into Violet Parr's.
"Violet," Helen said, "I'm so glad you're finally here!" And as that name entered his head, Robert felt a wave of memories flood his mind. He welcomed it, knowing that he was with family again. She closed her eyes as Violet's personality took over. She opened her eyes, no longer afraid. Looking in the mirror again, she rubbed her new body sensually, pleased with her appearance.
"Oh mom," she said, "I feel incredible!"
