3. Deep Penetration
Again, she lies down on her stomach, but this time her legs are spread open and her knees are bent (her feet should be in the air).
Using your hands for support, straddle her slowly at first, but make sure your legs are together. This allows for deep penetration, and whether you thrust slowly or quickly, I can virtually guarantee that both you and she will achieve monumental orgasms.
To add variation to this position, simply angle her thighs in different ways.
