See the Raider's Girls' show

"If you will now direct your attention to the stage," says Ilsa, speaking through a magical voice amplifier, "we'll be bringing out our next performance. When they've got their clothes on, they're the girls' powerball team representing the Eagle house. But now, after an ill-advised bet with their rivals in the Dragon house..."

A rowdy group of girls in red and gold uniforms gives a big cheer at the mention of their team. They clearly know what's coming, and are absolutely giddy about it.

"...they come before you as Raider's Dancing Cuties! Let's give it up for 'em!"

The stage curtain is pulled aside, revealing eleven girls in short, white bathrobes. Most of them are a mix of embarrassed or angry, especially when the hoots and jeers from the Dragon house team start up. As one they suck it up, turn around, and drop their robes, leaving themselves naked with the words "Raider's Dancing Cuties" printed one letter per buttock across their asses. The music starts, and they go into a song-and-dance routine that involves a lot more butt-shaking and cheek-slapping than they'd prefer.

"The Raider is the coolest! The Raider is the best!
The Raider is the reason that we're all of us undressed!
We tried to run away from him but it could never last
The Raider took our dresses cause we're simply not too fast!

The Raider loves the girls! He strips us every day!
We're such a silly gender that we never get away!
We thought that we could fight him off but we were really wrong!
The Raider took our bras off cause we're simply not too strong!

The Raider makes us steamy! The Raider makes us swoon!
The Raider bends us over and then makes us girls moon!
The Raider owns my booty! The Raider owns my heart!
The Raider took our panties cause we're simply not too smart!"

The Dragon house girls are laughing hysterically and calling for an encore. Perhaps you could get the Eagle house girls to give them one. Or perhaps there's something else fun to do.
