Sister Stacey is conducting a class in male anatomy when her phone goes and she is called away to the Mother Superior's office. The giggling schoolgirls are left on their own staring at diagrams of penises when Jody arrives to deliver a package of frogs for their biology class later that day. The girls have a practical of their own in mind, though, and they grab him and pull him into the desk and start stripping asking him innocently if he has a penis and can they see it? Jody tries to stop them but the five young girls are desperate to see what's in his trousers.
