Gum and Hum. (Gum and Hum) When a woman of any age removes her dental anatomy to perform a specific type of fellatio that combines both rubbing the shaft and tip of the cock with one's gums and humming different jolly time sea melodies.
Last night was boss! Edith gave me the old "Gum and Hum" and we aren't even going steady! Gee, my knob sure felt keen!
