It may look relaxing but actually demands too much vigor to perform. It gives ample opportunity to both the lovers to thrust harder against each other for the deepest possible penetration.
Steps to perform:
Step 1: Woman with folded knees, bends her upper body forward and rests her hands on the surface.
Step 2: Man now comes from behind with the folded knees.
Step 3: He grabs her butts and waist to get into the position and both start moving one another to get the deeper penetration.
