"You really like that, don't you?" Jon asked.
"Yeah," Sarah said, then began to drink the rest.
"Actually ... you don't like to drink urine," he said, with a smile.
Suddenly, Sarah's eyes went wide when she realized what she was drinking. She got sick and vomited all over the mall floor, right next to where her friend did it just seconds earlier.
She threw the cup of urine, accidentally hitting a shopper. She didn't care. For some reason, she had just drunk piss. Jon's warm piss.
As vomit and urine still dripped from Sarah's mouth, she glanced over at Jon. He was doubled over. But he wasn't sick, like Sarah. He was laughing. She didn't know how, but he did something to her to make her drink piss.
She wasn't going to let this prank go. Jon was gonna get it. Sarah was sure about that.
