2. The Leg Spread
With her lying on her stomach with her legs straight and closed, straddle on top of her. Your legs should also be stretched out, and somewhat spread. Your arms should be straight and holding you up. Make your way in and keep in mind that this position works best with deep, slow penetration.
And if you feel like getting romantic, bend your elbows and kiss her mouth. She will, however, have to meet you halfway.
