Anything you say? I have one for you, if you can.
It's a story request. It involved a woman living alone in her apartment who volunteers for an experiment to make her orgasms last longer or prolong them. The guy injects her with a serum that will do such a thing, but as its still in the testing phase, it turns her into a dog as she masturbates. The scientist watches from the other room and says that while the serum worked, she "will always be an animal in bed." Later on, she walks by a pet store and sees a dog in the window. She brings the dog home and presents herself to him. He mounts and she begins to transform again. It's possible a dildo is involved in one or both of the scenes.
It was on dA a long time ago but I can't seem to find it anymore. If I remember correctly, the user also had some manips of women turning into dogs on his page. Is there anything you guys can tell me about this story? It would be much appreciated.
