The Butterfly position is extraordinary for the edge of the bed, sofa, or almost whatsoever border for that matter! To come in this posture, the women lays back on nearly any edge sufficiently broad and often sets her feet on the floor, whereas the penetrating mate kneels or stands between her legs.

Make your bottom lie on his back. Kneel in front of him. Push his thighs in the direction of his shoulders, and press his legs down. As you lay all your weight on him, you penetrate. This is a very good position if you like to dominate and you partner likes to be man-handled in a powerfull way. It gives maximum depth of penetration, and gives the top complete control. Very satisfying position!

This position is excellent for inexperienced bottoms as they can regulate the depth and speed of penetration. The bottom squats over the top face-to-face, and lowers himself on the top's penis. When he gets more familiar with the position, he can penetrate himself with a screwing motion while at the same time constricting and relaxing his ring-muscles. See picture 1.
