Sister Nash enters her office to find a mysterious gift - a package with some delicious-looking cookies and a note that says, "To Sister Nash, from your favorite student." The unsuspecting nun bites into the first cookie and immediately realizes that her robes have become unbearably uncomfortable. She starts to strip, but is surprised to realize that her breasts are bigger and more sensitive than she remembered. Continuing to munch on the tasty treats, she feels a strange sensation between her legs and has the terrible desire to touch herself, an act she's never tried before. After a few failed attempts to stop herself and a few more bites of cookie, she gives in and fingers herself to the first orgasm of her life.
