Watch MoviestoWatch. First Base explores the moment at which sex is still only a titillating possibility and girls are still allowed to be attracted to other girls. It does so in a style teenagers can relate to. Their busts augmented by water balloons, Siler's nymphet heroines head out through their mushrooming slice of suburbia to try their luck with a couple of conveniently available teenage boys. The results satisfy their childish curiosity, but perhaps there is something more promising waiting for them when one sleeps over later....Tasteful and up-beat, First Base is appropriate viewing for all ages.
