Snookered. The Gang, #11

Ursula is a very good snooker player, and she's going to need all her skill in this very special game. Playing against a team of five men, each taking turns, she loses a piece of clothing every time they score another ten points. They all shed a layer whenever she gets ten as well. So the race is on to see who can score fastest, and who gets naked first. Then, when the game is over and no-one's wearing a stitch, the boys get to take turns again, but this time with Ursula, swapping and changing until they reach the messy finish she wants from them.
They're making the rules up as they go along, and it's going to be the best game ever.
