A rhythmic form of vaginal stimulation involving the pointer and middle finger. This can be performed on ones self or done to a willing partner. While this may be used to refer to the simple act of fingering, it more specifically describes a palm upwards technique. This approach differs from the standard "come hither" goto g-spot stimulater by way of independent finger movement.
