Ducker Up
V. - To "pucker up" in preparation of kissing/sucking a dick. The special formation of the lips and tongue was invented by a roundtable commission of egyptian, blasian, and exotic sod women in 2005. It involves a bell-curvature on top lip and a miniature inverted bell-curvature on the bottom lip, with the tongue's center wrapped in a U shape and the sides flattening out to either side. This provides ideal sucking for those who get the meat of their pleasure from providing head.
