One of the most exciting sexual positions for both partners. The male partner lies horizontally on a flat surface, and the female partner crouches over him, facing his feet. She then lowers herself into his penis, which has been held in a vertical position by either partner. The female takes pleasure by exposing her bottom, anus and vulva to her partner, demonstrating her complete submission to his desire. The male partner is able to feast his eyes on the sight of his penis disappearing into the lowering vagina, between the parted buttocks and legs of his beloved. The female partner has almost complete control and is able to determine the depth of penetration, changing at will from slight insertion of the glans to a full depth descent onto the erect penis.
