Daddy has had Princess locked up in her cage for a long time and she is very hungry and thirsty. Daddy isn't letting her off easy though, instead he's making her earn every single piece of food and water he gives her. Daddy is training Princess to be a good little slave for him, and so every time he feeds her a small square of chocolate she has to suck his cock through the cage. Even water has to be earned with some cock sucking and if it's anything less than the standard that Daddy expects then she will get nothing
