on all fours
palm to elbow flat to floor
ass high in air
forehead close but not touch floor
crawl to within 1 inch Masters feet

A crawling position. The slave gets down onto all fours, keeping her forearm level with the ground so that each 'step' she crawls on both elbows and palms. Butt in the air, her head is lowered so that her forehead almost touches to the ground. In this position she then crawls to the Master's feet.
