Jenny has to guess which girl's name is written on the card... she indicates her guess by removing that girl's top.
If she's right that girl gets pied too. But if she's wrong, Jenny also has to bare her boobs, and she takes the pie. So who's going topless and who's getting pied. At least one of these beautiful ladies will end up topless, and pied.
Will it be Luna, Carmen or Jenny who loses their bikini top and their dignity? If you need a spoiler, pop me a dm.
