Wasn't it nice of your father to come right to the door to escort you inside, honey?
I think you should thank Daddy for his hospitality. After all, his money paid for the rent of this hall, not to mention the food, drinks, -and the lubricant.
(Open up a bottle of lube, and spread it generously all over your cunt. Slip one finger inside. Now another. Now a third. Make yourself nice and wet....Good girl....Start playing with your pussy and don't stop until I order you to do so.)
