Covering up
From Voyeurweb's Wiki about Sex
Covering up is a standard erotic pose of where a nude girls tries to cover private parts like tits, pussy ass or anus with her hands while being photographed. Of course there is no way to cover every private part completely, so there is almost some private part revealed in a covering up pose. The cover up pose can be run on a completely nude girl from all angles or on a topless girl, where she tries to cover her tits.
