Concupiscence, noun: strong desire; especially: sexual desire.
[Origin: Middle English, from Anglo-French, from Late Latin concupiscentia, from Latin concupiscent-, concupiscens, present participle of concupiscere to desire ardently, from com– + cupere to desire.]
It wasn’t like an apple, or any crisp fruit, where you might sink your teeth in and lever a piece away from the orb. She bit through, faint resistance of the skin and then concupiscent flesh. Juice slicked her cheeks and chin, coursed down her forearm, dripped from her elbow. The flavor was—intense. Honeyed, but not cloying, complex and buoyant. – Dust, Elizabeth Bear.
