She has to sing it again, this time without panties.

"Please, not in front of Amy! I barely know her!"

"Well, you should have thought of that before bringing her with you to our house uninvited. We'll get to the punishment for that in a minute. But first, lose the panties and sing the song again.

Shyly, Janet removed her pants, then, turning away from Amy, slipped her panties off and pulled her pants back on. She stepped out the door and Amy's eyes were drawn to the thing lying discarded on the ground. She wanted to say something to try and help Janet out, but what could she say? What could she do? Nothing but stand on the stairs, bottomless, and wait to see what happens.

A moment later, Janet came in and did her whole song and dance again, only this time when she pulled her pants down and twerked, Amy could see everything, the light blond peach fuzz on her mound, the glistening moistness of her pussy lips, even the little pink rosebud of her asshole. Amy found she was almost as turned on by another's humiliation as she was by her own. She worried that, since she didn't have any pants on, the girls might be able to smell how aroused he was getting from this ridiculous show.

She was so focused on Janet's bare ass, that she hadn't noticed the other girl leave the room and come back with a wooden paddle. When Janet sang, "if you want to spank me come along!" the woman pulled it back like a baseball bat and swung the paddle at Janet's ass with a loud "THWACK!" that elicited a cry of pain and surprise.

"Good. Now that's settled. How should we punish you for the uninvited guest?"
