In this simple side-by-side position, you lie with your faces close together. This creates an intimate mood of warmth and tenderness. Both lovers lie with their legs outstretched. The woman rests her uppermost leg on top of her man’s leg, bending ti a little to allow him into her. He pulls her toward him by grasping her thigh.
From The Perfumed Garden:
EIGHTEENTH MANNER (Love’s Fusion) – While the woman is lying on her right side, extend yourself on your left side; your left leg remains extended, and you raise your right one until it is up to her flank, when you lay her upper leg upon your side. Thus, her uppermost leg serves the woman as a support for her back. After having introduced your member you move as you please, and she responds to your action as she pleases.
