In her sleep Zoey's balls finished forming. They churned once and unleashed a flood of semen that spurred forth from her new cock and flew out to coat her shirt and face. This woke Zoey up as she was startled by it splashing her in the face.
"What the...." was all she could say before she had to process a few things. First, there was a slowly receding donkey penis in front of her chest. Second was the semen that now coated her upper body. Third was the fact that this had come from her and that the penis was attached to her.
She ran to her bathroom to check herself out in her full length mirror. In the reflection she saw her curvy feminine body but her attention was drawn to the animilistic sheathe with a long 15"cock sticking straight out and a pair of large black balls below it that replaced her once petite vagina.
"this is crazy... I've got a penis somehow! And not even a human one! What am i supposed to do?"
"You're supposed to dominate" whispered a voice in her head
"What? Who said that?" She wasn't sure if she was hearing things or if she had thought that to herself but one thing was for sure. But she could understand what the voice was getting at. There was something different about her beyond the physical. She had a feeling in her now that she couldn't quite grasp, like she wanted to be in control, to rut, to breed and to mate, and above all to love it as she did it.
Her mind began to cloud over a little. Yeah that sounded... right. She could do that. There was a tool in front of her now that she'd never had before, a tool that would let her do the fucking she wanted without all the stigma, without having to care or get attached to someone. Guys were always fucking around and not caring and who wanted anything more than that really. The more she thought the more it just made sense that what she had was a gift and not to be removed from her. It was hers, her cock, her balls, and she was proud of it, not even questioning where it came from.
Of all these thoughts that crossed her mind, one stuck out, the desire to feel its power. She looked at herself in the mirror and watched herself raise a hand to meet her donkey dick and smoothly run down its length from top to bottom, stopping to heft her balls and feel the weight they carried, the potential baby making material. There was a need in her, a deep desire, to fill another with this seed, so that they overflowed and were full of it.
