Something alluring is attractive and enticing. Alluring things are tempting.
You might notice the word lure lurking in alluring — that's because alluring things lure people in by getting them excited and inspiring desire. Sometimes that's in a sexual way, like when someone wears an alluring dress that shows a little skin. But a homemade chocolate cake would be pretty alluring to a chocolate lover, just as free World Series tickets would be alluring to a baseball fan.
