The following position is quite demanding for both partners, because it requires strength and flexibility for both. First, the man kneels on the bed in a heel seat, his legs are closed or only slightly open. From this position, he leans his upper body back and supports himself with his hands behind the body. His lover stands with spread legs over him and slowly squats down until she sits on him. She inserts his lingam into her yoni, embraces his waist to support herself, and makes her pelvis slowly circle or rock up and down.
