Your eldest daughter, Jessica
From Create Your Own Story
Your daughter Jessica is the pride of your life, she is the definition of model student, a 4.0 student every semester who volunteers at the homeless shelter and is a nationally recognized athlete in soccer who has just gotten a full ride scholarship to Stanford for soccer. She is 5'8, 125 pounds with silky brown hair which she always has pulled back into a ponytail. She has a small frame for her height and her breast are perfect B cups.
You enter her room and she is studying while absently juggling a soccer ball. She looks up at you, "Hey dad, whats up?"
You were just going to come in and tell her you were a god but looking at her now you feel your dick give a slight tingle and reconsider. You could just tell her, of course but there are some other options available. You could give her a bad case of the Electra complex, sexual interest towards dad. Or you could subtly switch reality so she's your adopted daughter. Or you could just throw the whole thing out the window and make it so you don't even have a family and she's your girlfriend.
