Imagine you've been talking to some young little slut on tumblr for weeks, telling her shes so sexy, how you wish you could be her dad, chipping away at her defenses to finally get her to send pics... and you recognize the wallpaper in her bedroom - it's YOUR daughter.
Or
Imagine finding a nice icky old perv that follows you, complimenting you and telling you how badly his big daddy dick needs you, how he wishes you were his little girl so he could fuck your 24/7, and when he sends you a pic of his cock... you recognize the shirt he's wearing - you got it for him for Father's Day, he's YOUR dad.
