When a woman is lying on her back and folds her legs on the sides, this position is called 'Indrani.' This position is used for penetration for a lot of other advanced and simple positions. This position enables deep penetration and can have the partners move in circular motions.
However, instead of having her legs bent or folded on the sides, she has them wrapped around his waist, looking like a toad. This is a slight advancement to the missionary position, wherein the man lies on top of his woman.
