Horny for the camera

"Yeah!" said Jen. "Let's make her grow horny every time someone points the camera at her."
"Great idea!" said a giddy Sharon. "And we'll have her be really confused and embarrassed at the same time."
"OK," said Arnold, "Kristina, you will become very sexually aroused whenever someone points a camera at you. You will have no idea why, and this will confuse you. You must make sure no one notices that you are getting horny. The more pictures that are taken, the hornier you'll become." He stepped back, "Anything else?"
"How about she gives herself and wedgie whenever she hears her name?" said Heather.
"Yeah," chimed in Jen, "and have her butt itch any time she hears the phrase 'thank you!'"
"OK, that should be enough," said Arnold. He gave Kristina the other suggestions.
"Now," said Heather. "We need a plan. I say we tell Kristina we have a Weather Woman Club, and we want her to be a member, but she has to undergo an initiation."
The other four women all agreed. "Yeah, she'll want to do anything to be a member of our club," said Sharon, "no matter how silly or degrading."
Arnold made sure that Kristina really wanted to be in the club no matter what. He then gave Kristina a trigger phrase to send her back into her trance. The phrase was "Kristina Deep Sleep."
