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. This lovemaking position is really comfy for both mates, although a pillow or some cushions underneath the knees may be practical for a kneeling penetrator.
