A slow tongue movement like a mollusk... a pleasure that can only be experienced with oil! The thick tongue of the lady wraps around the head of the penis with a crawling mechanism of a gastropod, using the mucus of oil. Ladies who know the physiology of the male body drip oil onto the penis and run their thick tongues over the slippery head of the penis, using their smooth, free-flowing, slow tongue movements reminiscent of a mollusk, keeping the penis on the brink of ejaculation, leading to a rocket launch at the very end.
