A sexual position in which the penis is lubricated and inserted in the vagina as it is in "doggie style," but with the male lying down and the female astride, facing away, in the upright position. The up-and-down motion is done in a sliding manner, with the clitoris being stimulated from the "under" side.
"Okay, baby, now let's try a backwards slide."
