I've marked this as co-ed because Antony appears in it throughout, but the only person getting messy here is Yiyi.

"A trip to the gungetank, then 14 pies and a bucket of slime for poor Yiyi"

We decided that stepbrother and sister Antony and Yiyi would settle their differences with a game of strip rps to see who got gunged with green gunge in the gunge tank... and then the loser would then take 13 big shaving foam pies, and just to really seal the deal, a big bucket of slime too. With a handful of sprinkles to finish them off.

Oh... and then after the losing model has showered themselves clean... we hit them with another pie anyway.

And Yiyi lost, and took the lot, to Antony's sheer delight!

No spoiler pics of the trashing, but trust me, you will love the mega trashing that Yiyi takes in this one.
