You start to feel a pressure in your back; like something is growing underneath the skin. Once you swallow the last of the berries in your mouth, the sensation intensifies. Your shrinking accelerates, and your ears stretch into a long, pointed shape.
Your waist begins to cave in a little as your hips widen slightly. Small mounds form on your chest as your face rounds out and your hair grows to shoulder-length. Your manhood then retreats into you leaving a small slit in it's place.
A feminine scream escapes your lips as your back begins to stretch at four points. You feel as if your skin would tear open at any moment, yet, it never does. The initial sourse of the pressure begins to branch off, broadening the thin sheets of flesh before they, at long last, settle down.
You slowly crawl out of your clothes to a nearby puddle of water to confirm your suspicions. Lavender hair, Colorful butterfly wings, long pointed ears; you've become a fairy!
