The female shuts her eyes, a muffled scream being blocked by the tube in her mouth. Her breathing is shallow and rapid, making it easier for her enlarged breasts to be noticed in the sterile lights. She opens her eyes again, revealing enlarged irises that take up most of where the scelara had been, a consequence of the chemical cocktail; a brief glazing over indicating that the baser emotions of a bestial stallion - of galloping and grazing and mares - had begun to impose themselves in her mind before they are blinked away. They move to the mirror and widen to reflect her horror at seeing her lengthening clitoris reach above her navel, just behind the frontline advance of the darkening skin.
With a futile thrash of her slowly-thickening limbs she shuts her eyes and twists her head a little trying to throw off the tubes delivering the chemicals, but they remained in place. It appears that when faced with the traumatic situation, she chose to fight it with whatever she had left, even if that would be just her own willpower - the feeling of continuing growth in her private areas served as a reminder of her limits. This had been the slowest progression that changes had been recorded in these trials though, the longest so far that the subject resisted the process - how this will play out physically and mentally would remain to be seen.
