From the Ananga Ranga: Sitting astride the man and facing him the woman stretches out her legs alongside his body, passing them under his arms at about elbow height and around his waist.
Movement can be controlled by the woman’s arms or he can pull her on to him. She needs strong arms to hold herself up for long periods.
Hard on the arms but I can wrap my legs around him and pull him in, gets a thumbs up from me!
Great, enjoy being able to pull her closer!
