There aren’t a lot of positive adjectives to describe lips. “Full” is the pairing that comes up most often, almost like a standard epithet, but that seems bland, and the alternatives mostly run to the sensual or downright pornographic. You can’t say someone has “perfectly labial lips,” because it sounds insane, first of all, and it’s confusing, bringing to mind something like Magritte’s “Le Viol.” The lips mentioned in Lucky Soul’s song, though, aren’t really described at all apart from being unhappy. They’re upset, one assumes, because of the distinct lack of kisses. These lips want the 1,000 basia of Catullus 5, kiss upon kiss upon kiss.
