Yes

"Yes," Summer admitted, blushing a bit.
"How do you indulge it?" Dr. Crane asked.
Summer looked uncomfortable.
"Don't worry, Summer. You can tell me anything. How do you like to indulge your foot fetish?"
"Sometimes, when nobody is around, I like to smell my own feet," the actress admitted.
"It's good that you're admitting that," the doctor said. "We all need to be comfortable with who we are. My goal here is to help you achieve that comfort. To that end, I'm going to give you some triggers. Do you know what a hypnotic trigger is, Summer?"
The celebrity nodded.
"Excellent. Your first trigger is 'Toe-tal slut.' When you hear me say that, your foot fetish will overrun your brain, and you will have no inhibitions about worshipping your feet in front of me. When I say 'brought to Heel,' you will be my eager footslave, happy to please me. When I say 'Sole control,' you will return to this hypnotic state. And when I tell you to 'put your Foot down,' you will return to your usual waking self, remembering everything that has transpired here. Do you understand?"
"Yes."
