Kajira of Gor, page 434

The slave falls to her knees and drops to all fours, her head lifted slightly as it is held straight in line of her back. Her butt is raised into the air and her thighs spread widely. This position is often a preparation for sexual use. The slave remains motionless as she waits for His command or pleasure.
