Lust.

Shamelessly wanting to indulge in someone's physical form; not for the purpose of expressing love, but for that of gratifying a selfish desire. Longing for their taste in order to satisfy one's own craving -as if they were a good meal- and then dispose of them -as if they were an empty plate, now destined to the dishes-. A rather brutal, but no less organic, force of human nature.
