"Yes, a lion will do very well for you. A fine guard a lion makes, and your stature already is that of a brave lion." Circe raised her hands to cast the spell, she knew she didn't have much energy left for this, but she had never run out before, why would she now?
"Felinis grandora Savanhta!" The spell had immediate effects, Eric's hair started to grow into a large silky mane, His clothes ripped apart to reveal shifting balls and a new sheath for his cock, now black and smooth. Golden fur spread over his body and a tail sprouted from behind him. His legs changed and grew, his feet becoming pads and stretching so that he stood on the balls of his feet. Giving him another foot in hieght.
"Not for long." Thought Circe, but she was in for a surprize. For at that moment, Eric stopped changing! He now looked like an anthromorphic lion, complete with a smooth black dick, that was now emerging.
This was the first time Circe had ever changed someone only half way, but she liked the results.
"You'll do fine like this, Maybe I'll change others in this way, to join you at your post." She lead him out to where he would guard, then showed him his sleeping quarters.
After leaving him, she pondered what to do next.
