Watching Billy's transformation, made Stan hard as a rock. He reached his hand into the jar of satyr cream and ran it up and down his long, aching member, anticipating different, but equally exhilarating changes.
Meanwhile Billy's ears elongated and began to twitch until they stuck up a few inches from her head of black hair, and were soon covered with a thin layer of fur. Two curved horns began to grow from her forehead just below her hairline as she dipped her hand back into her wet pussy and moaned as she lost herself in the pleasure of her changes. Her feet changed, as her toes merged into two black, hard toes. A warm tingling sensation enveloped her tailbone, and wiggled her butt from side to side as she felt a long, hairy tail begin to snake out between her butt cheeks. A thin layer of fur covered her body, as her lips and nose went almost as dark as her hair. She bleated with pleasure as her transformation was sealed, eager for her mate to join her.
