His mother, Dehlia, draped herself over the arm of the sofa, unaware of how her ever move became more graceful and lithe, bordering on sexual. Her breasts ballooned outwards, filling up her shirt. Chris could hardly keep his eyes off them. Behind her, her legs grew longer, as did the rest of her body, until her clothes looked painted on, showing her newly-forming muscle tone. Chris' gaze wandered lower, finding the camel toe of her pants growing as well, and soaking through her panties. It seemed that Chris wasn't the only one enjoying this.
Dehlia watched his gaze wander fondly, before reaching over and tilting his head to meet her solid gold gaze. Chris startled as he realised that just one of her arms was long enough to reach him, meaning it was nearly a metre in length. Running the maths in his head, he calculated she would be more than 2 metres tall. The revelation came with both shock, a twinge of terror and a tightening in his pants.
With her muscled arm, Dehlia pulled him closer to her, inhaling deeply as if smelling his hidden desire. "Darling," she purred, her voice now silky and sensual, passing through her dark, plump lips like honey. "I'm feeling especially thirsty today. Would you be a dear and grab me another cup, please?"
Chris thought he was paralysed, staring at his mother in awe as her skin became a dark caramel, her height increasing by the second, but something in her voice compelled him to do as she said. A haze of gold overtook his vision, as he robotically walked and poured another, larger cup of coffee.
It was just as he was about to bring it to her that he shook off the stupor, and glanced down at the cup in his hand. The vial had, in a single dose, transformed his mother into a massive bronze goddess. If he just added a few more, who knows what it would do to her! He felt his cock stir in his pants at the thought of transforming his mother into the gorgeous fantasy he'd always dreamed of. Quickly, he opened the case of vials and got to work.
