What could these girls be doing to each other?

Some would say this is just another pictureholic duo trying to perform the lady thing in an open environ, but is this not suggestive enough that something is going on than meets the eye?
You wouldn't really blame anyone for thinking out of line concerning these young ladies, it is a well known fact that lesbianism has gone past what it use to be in the days when it was still finding its way to the surface; right now people come out openly to let us know how they feel for their own kind. If you caught your daughter or sister in this act would you over look it?
