Point out the keys and see what happens

You don't know what to say. You're completely at a loss. Dumbly, you point at the keys behind the tire.

"Oh!" The girl whines, "I can't believe I missed that!" She grabs her keys and leaps up. "I've got to run, but thanks for the help!" She gives you a quick hug and then jumps in her car, clearly excited to be free from her quest.

Jasmine looks at you and shrugs, "What?"

"I...I thought she agreed to a blowjob," you say, confused, "why did she leave?"

"The same reason I stopped jacking you off once you mentioned it," Jasmine muses, "She already agreed to a blowjob, so why not offer it? She was just supposed to thank you, to blow you a little after you helped her find her keys...but you skipped ahead. You didn't even search for them, just told her right where they were. It's like, you skipped the script, and that broke the spell."

You take a long breath and look at the girls's car as she drives away. "A script? I thought we agreed this wasn't the Truman Show."

"It's not," says Jasmine, "but it does seem to be following some kind of narrative structure. I have another experiment. Find a pretty girl, and tell her that for your homework, you have to experience an orgasm for the first time."

"You can't be serious."

Jasmine looks you dead in the eyes. "I'm serious. But this time, don't break character. Just act wide-eyed and innocent, and see what happens. Don't you want to figure out what's going on?"
