Christy was on the teacher's lap, up front with Ms. Black, the most prized spot in the classroom during break time. The other little girls in class 307B were all talking, eating snacks, getting diaper changes by Tina the teacher's assistant, or playing, but Christy had good behavior and got the best reward of all, and that was Ms. Black's breast milk.
Ms. Black's button-up shirt was open, showing her large breasts and nursing bra underneath. Resting on her lap was Christy, who was wearing nothing more than a thick white diaper. The other kids all wore at the very least shirts to cover their chests but Christy was quite happy to be nearly naked and let her bare skin rub up against the warm and soft fabric of Ms. Black's clothing. It was not really unusual for kids at Diaper Elementary to spend most of the day in this sort of undress, and Christy actually rather enjoyed it.
Christy quietly suckled and made an occasional happy moaning sound as she did. Her bare skin, ghostly pale, and her light hair, a silvery blonde, almost seemed to shine in the fluorescent lights of the classroom. Ms. Black giggled and cooed as the little girl in her lap drank from her. She liked to rub Christy's skinny torso, especially her tummy, as well as the front of Christy's diaper. Just as Ms. Black moved her hand there, Christy began to uncontrollably wet herself. The little girl stopped suckling for a moment and took a couple deep breaths.
"Oh, there, there, little one. Keep drinking, we can change you when you're done." Ms. Black said.
Christy nodded and continued to suckle, enjoying every moment of the contact with Ms. Black's large wonderful breasts, and creamy, tasty milk.
Once Christy was done, Ms. Black took her to the changing station. Expertly, she removed Christy's wet diaper, cleaned her up ,and got her into a new thick white diaper, the only thing Christy was wearing.
Now that Christy was clean, what does she do?
