This is a kind of variation on the lotus or a move that can be incorporated into it. Once again the man sits cross-legged and the woman sits in his lap but instead of wrapping her legs around him she instead uses a hand to guide her leg back and forth. Be sure to use whichever side you find is dominant or easy for you and start this by taking it slowly. It is an interesting position because it allows stimulation without the usual kind of control over what you are doing so it feels more natural in a way. It can look a little bizarre but it is definitely a position to try out if you are looking for new experiences. It might not allow for the same kind of caressing.
