A healthy snack of celery sticks and peanut butter is a ton of fun when it's just you and Natasha. You don't mind if she tosses proper table manners out the window and goes to town, taking big bites and chewing with her mouth open? With the focus on her mouth, you get to see every little detail. Her big white teeth tear into the vegetable and grind it into a pulp. She opens her mouth wide so you can see how messy her tongue is and the tiny bits that are stuck between her teeth.
