Sally snuck out of the castle to go outside. Luckily she ran into no teachers. "Everyone must be sleeping.", she thought to herself. She saw the black abyss of the lake and decided that this was the place.
Glancing around, she saw no one, she stripped down to her birthday suit. She felt the moonlight touch her bare skin and relaxed. Sally got down onto all fours, the weeds covering her up, she let the change begin. Nothing felt better than changing her skin. She was an animagus not a werewolf. Her mouth and nose elongated, a tail grew out of her tailbone, the fur started to sprout out of every pore in her body.
The change had ended, feeling better and freer she took of running around the lake. As fast as the wind she took off and felt the grass brush up against her fast moving body. Once she ran one lap around the lake, she collapsed onto the floor.
