Lustier is the comparative form of lusty, meaning more vigorous, hearty, or full of vital energy.
A lustier voice carries more power; a lustier appetite shows greater enthusiasm for food or life.
The word retains its connection to robust health and spirited energy rather than purely sexual desire: The chorus grew lustier with each verse.
