A Cruel Idea

As John watched Demi run her lap, he had a fun idea.

First, he'd use his time powers to put Demi in a loop, making her run over and over again, but he'd also make her age up slightly with each lap she completed. He hoped she'd become a cougar by the time he was finished, but he would have to wait and see.

Demi finished her lap, and John allowed her to catch her breath before looping her.

Without breaking a sweat, Demi ran another lap as her loop began.

"Look at my tits, look at my butt, I'm Demi Lovato, the Central Park slut!" she chanted over and over again.

John sat back on the bench and waited to see how old he wanted Demi to become before pulling her out of the loop.
