Approach Jennifer and the girls

You burst through the door and lead the Daisy Chain inside. The WAR girls, realizing that boys can suddenly see their bare butts, give a little scream and yank their pants back up. Jennifer scowls at you.

"Boys, get out!" she says. "The door was clearly labeled, 'Do not enter: Girls undressing!'"

"You call that undressed?" you say. "C'mon, Jenny. You should know the meaning of 'undressed' by now. After all, it wasn't that long ago that you were the cover girl of Raider's Big Coffee Table Book of Eastern Girls Getting Caught Naked by their Favorite Teachers."

You hold up a book. There, on the cover, is awkward-phase Jennifer in her glasses, her headgear, and nothing else. She's got her foot up on the wall, trying desperately to pull a locked door open. She's also looking back in horror at Professor Lovegood, who evidently just rounded the corner to get a surprise look at her cute little ass, her cute little breasts, and her wide open legs.

Jennifer turns deep red.

"Naked girls are supposed to be enjoyed, not hidden away!" you say. "That's why Lolly is jiggling around for her friends here. So, why don't you and your guinea pigs save some time and do a fun little striptease for us before we have to make things really embarrassing for you?"
