"Alright," said Jon, standing in his bedroom and clutching the wish rock, "Let's figure this wish out."
He was noticeably distracted by Karyn, who let her blouse fall freely to the ground. Fishing in her bra, she lifted the miniature Sarah free from the enormous blue cups, revealing her own, albeit grape-sized breasts.
"Maybe not potions?" said Karyn, "They're kind of unruly and they seem to run out."
"Well we can always wish for more," said Jon.
"Okay, fine," said Karyn, "at least that way we can finish Sarah off."
There were squeaks from the two giant breasts that Karyn placed gingerly on the bed, but Jon and Karyn did their best to not pay them any mind.
"Here goes," said Jon, "I wish I had more shrinking serum."
As it had earlier in the day, a small vial appeared atop Jon's dresser.
"Haha!" laughed Karyn, grabbing the vial and rushing over to the breasts on the bed. She pulled the stopper in the vial and let two drops fall, one on each of Sarah's ginormous breasts. They instantly began to reduce in size and, in moments, there was a five-inch woman on Jon's bed.
"Brilliant!" beamed Karyn, plucking the naked woman from the sheets and examining her.
Screams came from Sarah, but it made Karyn smile.
"Now who's the freak?" said Karyn.
"Fuck you!" shouted Sarah with surprising ferocity.
"Can I keep her?" said Karyn to Jon.
Jon laughed, knowing she was kidding. They'd have to restore her sooner or later.
