"Mary..." Danny started to say. But Mary, with new found confidence from her balls, blurted out a long suppressed desire.
"Can you turn me into a satyr?" she asked unashamedly. Danny blinked only once before smiling at her and nodding. Sara emerged from the shower, dripping water and small amounts of cum onto the floor. Her sensitive ears picked up every word of Danny's and Mary's conversation.
"I've never done it with a goat before. This could be fun," Sara thought. She kept her distance as she watched Danny hand over the "Goat Vial". He'd measured out what he thought was a reasonable dose. It wouldn't turn Mary into a complete animal, and this time he hoped she would be more in control of her feelings.
"Bottoms up!" Mary said gleefully. She downed the vial in one large gulp, and giggled as a heat flooded her body.
Below, her feet cracked and changed their shape. Her toes fused and then split in half. Hard nails spread across her two toes, and in the end Mary was left standing on thick digitigrade legs. Fur, long and brow, sprung forth from her thicks and a small nub of a tail. It flicked and rubbed against the rest of Mary's fur.
She giggled against, when the warmth was centered on her clit. It didn't take long for her clit to swell, and push out into a sizable ten inch goat penis. Below, her ovary balls turned into testicles, and her penis began to spit out pre. Short, curved horns few from the top of Mary's head, and wispy hairs appeared on her elbows. Her breasts grew out, quickly going from a C cup to something more like an E or F.
When the transformation was over, a new satyress stood before Danny, and Sara.
