Samantha and her prize-winning stallion were taking an evening walk along the beach by their home. She always loved taking these walks with her horse. They calmed her down, letting her collect her thoughts and contemplate the previous day. She also loved spending time with her stallion, Goliath, who she'd known all her life. Goliath had been her horse since she was a child, and the two were practically inseparable. That was, until a shadow passed over them.
Jen came tumbling down the hill. Her massive body blotted out the sun over the girl and her horse, causing them to look up. Samantha shrieked as Jen crashed down on top of them. Jen felt the change initiate, as Samantha's and Goliath's head squeezed onto the top of her old body, and she was left with theirs.
She looked up as her old body stood up. Sitting on the shoulders of the giant was the head of a 20-something woman and a massive stallion. The two stumbled, trying to sync up their human and equine instincts as they walked away, back along the beach. Jen tried to sit up, but found it difficult. She felt utterly bizarre. A human body lay before her, but something stopped her from moving her neck like normal...
She screamed as the feelings hit her. Above her human neck, another neck bent town. Because Samantha was walking slightly ahead of Goliath, and not riding him, the two bodies were separate. She quickly realized that the second neck was that of Goliath! She was both a girl, and a stallion! .Her instincts kicked in, and she quickly got up and walked towards the beach. Her human body walked normally, and her horse body leaned forward a bit to match the height. Jen was weirded out by feeling a normal human body and a giant stallion body walking in tune behind it, and she wondered how she'd ever get used to this. Her eyes darted back and forth, hoping beyond hope that someone would come around the horizon to save her from this freakish existence, but she was on a private beach. No one would come. She was stuck like this.
As soon as her human toes hit the water, she collapsed. She looked behind her, and felt her two necks crane. She was met with the sight of a gigantic stallion behind her, towering over her human half. She reached out, stroking the fur, and started to cry. She couldn't believe that that horse was part of her, was her. Crying, she lay there, her horse body laying with her legs tucked under it while her human body lay splayed, sobbing. She was a freak of nature, not even a centaur, but forced to share her normal human body with a massive stallion right behind her! How could Kyle have done this to her!
As she sobbed, she felt someone come and brush her fur, feeling herself calm down. She looked up to see...
