(sorry for the paragraph)
First get them drinking a lot. Then get Christina panties off and stuff them in Penny's mouth. Penny gets put in a fucking machine set to full blast. Watch her get jackhammered relentlessly.
Christiana can save her by drinking a glass of her own piss. Piss witch she can only collect by wringing her panties into that glass. That means Christina has to piss in Penny's mouth, soaking her panties, pull them out, wring all the piss she can into a glass then put them back in Christina mouth and repeat until the glad is full. Then she gulp it all down.
