Jennifer now had all sorts of ideas running though her head, but one stood out among all other. She had no idea why, but she was starting to see images of big manly bulls in her head. So she turned to Susan and said "I think you should share this experience with me." "What do you mean by that?" Susan asked. "Susan," Jennifer started "Transform in to a bull, but keep your human mind a voice." "Huh," Susan said, very surprised by her friend's choice, too shocked to say much else. But then she felt tingling all over her body. First her hands and feet merged, becoming hard and black. Then the transformation worked it's way up her legs and arms, making them longer and more beast like. As this occurred, hair started sprouting up in the places that had just finished transforming. And as Susan's arms and legs reached their full length, she felt her back crack and give way, which forced her down on to all fours. Next a tail began to form out of her tail bone. And almost simultaneously, she quickly began to gain weight. As more hair spread across her body, she felt her face start to push outward and the top of her flattened out. Soon her ears popped out, just as Jennifer's had. With all of this almost complete, something ran though Susan's mind, Jennifer had said bull, not cow. And as if in response to this thought, Susan felt a great tingling between her new legs. Then to her surprise, she felt a large, long bull cock come out of her new sheath and become erect. With all of the changes completed, Susan turned to face the mirror, only to see a large black bull with a huge erection staring back at her. Susan then turned back to Jennifer, who seemed to have a grin on her face and asked "What the hell is this? Why did you turn me into a bull?" Jennifer could only reply "Sorry, but this was all I could think of, besides, after this is all over we can change each other back." That was true, but for some reason now Susan began to get a strange urge to go over to her friend. And a the same time Jennifer approached Susan. "What going on?" Susan asked her friend whom she was now becoming more and more attracted to. Jennifer replied "I am a female cow, and you are a male bull, what do you think is going on? Besides, even if I wanted to, I don't think I could resist such a big manly bull such as your self." And to her surprise, Susan found herself mounting her friend and the found her mark. She then stuck her new big bull cock into Jennifer and it felt great. She could believe that not to long ago she was a regular high school girl, and now she was a large male bull mating with her best friend. But she no longer cared, she just kept humping away. Both girls now lost in the passion of what they were doing, even had forgot they were animals.
Soon they finished, but they both had really enjoyed it. "So what do we do now?" Susan asked. "Well," Jennifer said. "We can go for a little more, cause I know I am up for it. Or since the curse is on you, we could try and experience other forms." That though hadn't crossed Susan's mind, but there were other things she had wanted to try, but right now all she wanted to do was get back on to Jennifer. And Jennifer see how her friend was acting knew what she wanted, and turned back around for another chance to experience please at her friend's hand, or now hoof.
