Derek tosses and turns all night, he finally sits up around 4, not able to get back to sleep. His arm starts to itch, and when he goes to scratch it he feels something soft, fumbling to turn on the light, he looks down at himself, and lets out a yell of surprise. His body is being covered by course black fur, his fingers are shortening and his nails are growing out into claws.
Struggling to stand up, he falls down onto his hands and feet as they turn into paws. He feels a pain at his back as a tail sprouts out, he manages to turn over in time to see his penis shrinking down, he lets out a yelp of surprise as he realises that its shrunk into a vagina. Struggling to see himself in the mirror, his nose and mouth push out to form a snout, and his body is completely covered in fur, his, now her tongue falls out as she looks at her new body, having been turned into a black lab dog.
This curse had turned him both into a dog and a female, he had to find Sonya.
