To get into this position she simply lays on her back while he kneels between her legs. She raises one leg and places it on his chest (wherever is comfortable for her). He can hold her leg in place while he thrusts forward. This is a wonderful sex position for several reasons. First off this position allows for wonderfully deep penetration but more than that because her body is slightly twisted and elevated his penis will position itself just a touch differently. Some women have said this position allows for g-spot stimulation but that varies from woman to woman.
Not sure what to do with my leg half the time, enjoy but I prefer the full press
Too much going on for my liking
