Clit masturbation
From Voyeurweb's Wiki
Clit masturbation is the most common type of female masturbation: Teasing the clit with her right hand (left handed persons use their left hand) through up/down or left/right or circle movement of one or two fingers and applying little pressure. Mostly every female has a favorite leg position, which can vary from wide spread to tight together or slightly pulled. See samples below.
