Some girls in fiction have it bad. Those whose fathers aren't useless, abusive, perfectly fatherly, or overprotective, will instead have pervert dads. These dads, while (usually) not going as far as outright incest, do look at their beautiful daughters with hungry eyes, liberally comment on their physical features (usually their breasts), or in rare cases even do... Things... With their pictures... They will also have to be carefully kept away from any and all school activity and classmate in visiting (thus also providing an alternative for dads with male children, or not content with leering at their own daughters).
