Head to toe

The man lies on his back with his legs spread and his penis
inside the woman, who also lies down on her back, with her legs
spread across his, her toes pointing to his head, and her head
away from him. The woman is in control. The partners cannot see
each other and sensation is concentrated on the genitals. This
position can be adopted from one in which the lovers sit on the
bed facing one another, their legs interlaced.
