Katy padded sleekly around her room. She liked the feeling of being a dog, and especially of being a bitch. She was in heat, and the feeling of intense sexual craving was like nothing she had ever known. She licked her own pussy for a while, the sweet scent magnified a thousand times to her sensitive canine nose.
Katy looked at herself in the mirror and admired herself. Just then, she caught a scent through the half opened window: male. She wasn't able to tell if it was the scent of male dog or mae human, and she didn't care. It aroused her and made her want to get out and follow it.
She remembered how, when she was in high school, she used to sneak out some nights to drink with her friends. Out the window, across the garage roof, on to the shed and down. Simple. Even simpler for an athletic German Shepherd. She nuzzled the window open a bit more and wriggled through, quickly jumping down the roofs and to her freedom.
