Your new innocent virgin nun roommate

One day there is a knock at the door and you open it to find a tall, blonde, and buxom nun standing there. She informs you that she's your new roommate. She comes from a highly secluded convent that has recently closed down and the government has had to find homes for all of its residents. She is willing to clean and cook to earn her keep, and she is intensely curious about the modern world because of her sheltered naivete and ignorance of anything more complex than what you could find in a medieval home.
