"Sorry to bother you." He said. "But, I'm a photographer and I'm doing a shoot in the park. Our model didn't show up today and you're little sister would be perfect!"

"Of course!" She said, to her own complete shock. "I've always wanted to model!"

Lauren's eyes bugged out. Why had she said that?! What she didn't know was this was all playing out according to Dennis's wishes...
