The man is lying on his back, with his legs partly open. The woman lies over him and blocks the soles of her feet on the top of his feet. She can then use this hold to move her body up and down as her partner's penis penetrates    her vagina. The man holds her by the waist to stabilize the position and accompany the motions. This position favours the stimulation of the clitoris as    it is rubbed against the     man's pelvis although the liberty and the amplitude of the              movements are  some what  restricted.
