Start by having him sit cross-legged on the floor or on the bed. She straddles him, and lowers herself onto him, while facing him. Once comfortably situated, she leans back all the way until she's lying with her back flat on the floor, with her legs hugging his hips as shown. For an extra thrill of dominance, he can place one of his legs over her body, as shown, to keep her lying flat. This position provides a sexy view for both partners and exciting sensations because of the unique arrangement.
