"Quiet, you!" the wicked Queen screeched, pausing her casting to fling another spell the prince's way. He tried to avoid it, but her aim was true, and it impacted him dead on.
The noble prince tried to fight it as before, but this was a much simpler spell, not rooted in the deep evil that the other was. He began to feel week again as the room seemed to grow around him. His muscles dwindled, but did not vanish, as his frame grew smaller and smaller. His manly, leonine beard vanished, as did much of the length of his mane, leaving golden fur and a shaggy head of red hair. Though his hands and feet remained powerful looking, large leonine paws, they were now attached to a much smaller, somewhat gangly teenage body, perhaps 14 at the most. His proud cock had dwindled to a mere five inches as well, and strained in arousal.
Confusion showed on the prince's feline face, now more cute than intimidating.
"Ahh, youth and lust, the simplest of spells. Go! Service your father while I attend to your mother," the witch said, pointing.
The once-more young prince's gaze followed her gesture to where his father lay bound, his youthened cock throbbing in anticipation. It suddenly dawned on him just what the target of the lust spell she had placed on him was, and he was horrified... and yet he couldn't deny his new yearning!
