Reversal

 Callum was the meekest, most self-effacing, most tractable person I'd ever known. He'd seemed like the perfect subject for my experiment. 

It had certainly been easy enough to slip him a few pink pills, and from his horrified reaction to his scrawny boy body sprouting breasts, it seemed safe to assume I was right. Once the pills had finished perfecting his body, bending his wimpy personality to my will would be simple.

However, as the process continued, his attitude began to change. Far from crumbling, the former boy seemed to relish his transformation. Growing in confidence with each alteration of his body. 

She seemed taller somehow, even though she was several inches shorter than Callum had been. She stood with a model's poise and moved with a dancer's grace. The sexy lingerie, I'd intended as a humiliating reminder of her feminisation, instead fitting her like silken battle armour. 

I shrank back, awestruck at the vision before me. Unable to understand how this goddess could have emerged from the timid boy I'd know. Her green eyes fixed on me, burning with cold fire. Her lips quirking into an assumed half smile.

Without needing to be told, I fell at my mistress' feet, eager to obey her slightest whim. Part of me still foolishly insisted that I should be the one dominating her, but I ruthlessly crushed the rebellious thought even as it formed. 

I was the eager simp I'd always secretly longed to be deep down inside, just as mistress Cally had become her hidden true self, and we would both be happy at last together
