Beth thought. She definitely didn't want to be a bull completely, she definitely didn't want to go back to her loser life as a human on Earth, the thought of being a minotaur had its appeal, but not as anyone's servant. This smug goddess who thought she was so nice to everyone was added to Beth's ever-growing list of people on whom she would someday get revenge. As the elven queen, she had established several secret caches of weapons and magic items just for a case like this. Why not use one of them to transform herself back into the elven queen and retake her throne? After all, her subjects must love her, right?
"I want to be a human girl in this kingdom" Beth said carefully, not wanting to leave any room for misinterpretation.
"Very well" said the goddess. Beth felt her horns retract and her body rear back as it changed from a quadrupedal to bipedal stance. Her body's bulk decreased rapidly, and her genitals changed from a bull's penis to a normal human vagina. She was naked.
"Clothes?" she asked the goddess.
"Not my problem" answered the goddess, who disappeared.
