Sister Mary Kathrine

Sister Mary Kathrine stepped through the door and closed and locked it behind her. She was mumbling as she walked towards us. "Well, well, well. Look who have been a couple of very naughty girls? Naughty naughty girls."

Neither Katie nor myself had moved an inch since we first saw Sister Mary Kathrine, and now she was standing right in front of us, still talking to herself about naughty girls.
She reached out and ran her fingers all over my pussy. She even inserted two fingers up to her knuckles. She then brought the fingers up to her mouth and sucked on her fingers. She then moved to Katie and proceded to stick her fingers in her pussy. Once again, she sucked her fingers.

"Oh, yes. Very naughty girls, indeed. Put your clothes on. We are going to see the Mother-Superior."
