You feel a burst of energy, a tingling over your whole body. The tasty morsel was fueling your change, your new body. The tingling bursts and hits the tips of your fingers. Shrinking before your eyes, your fingers drop their human nails out onto the ground. Your eyes grow as big as saucer as your fingers burst with fur and are reduced to inhuman paws. As if by magic, the thumb shrinks and moves becoming non existant to your eyes.
You scream, but a single bark comes out of your throat. What could be happening here! You think as you feel some movement and changes from inside your pants. Expanding pressing hard against your pants!
