"You think it's so easy" Jon said "Wanna make a bet?"
"Depends what's the bet" Zoë said still in a towel
"You drink two gallons of water and for the next ninety minuets you have a bladder the same size as mine" Jon said "If you don't feel as frustrated as I do or piss yourself you win"
"Sounds interesting what's on the line?" Zoë asks
"If I win you won't be able to talk regularly for the next forty six and a half hours only sing" Jon said
"That's a very random time amount, but what if I win" Zoë asks
"I already have a pussy so the rest of my body will change to match and six extra hours will be added my current penalty, except the bladder of course"
"Hmm, if you're small bladder ends at the original time, you stay a girl for a full forty eight hours"
"Deal"
After Zoë downed the two gallons she went to change, and Jon barricaded himself in the bathroom.
