Offer a special service at the photo booth.

"Mackenzie, I want you to listen to my orders very carefully." Amanda said firmly. Mackenzie nodded eagerly. "You're going to go back in that photo booth, and take your clothes off. After you hand them to me, you are going to stay in that booth and offer your mouth up to the next person to enter the booth."

Mackenzie's cheeks flushed. "Wh-what?! Amanda, I can't possibly do that!" she protested. "It... it would be humiliating!"

Amanda stuck out her bottom lip in an exaggerated pout. "Please, Mack? For me?" she pleaded. "I'll give you a special reward!"

The hypnotist could see Mackenzie's resolve wavering already. Her hypnotically induced desire and weakened willpower were making this almost too easy.

"...You'll enjoy me doing this?" Mackenzie finally asked.

"Yes! Oh, don't forget to make sure the camera gets good shots!" Amanda instructed, taking Mackenzie by the shoulder and ushering her back into the booth. "Now go ahead and give me your clothes! We don't want them getting messy when you finish up your first visitor!" she said. "In fact, I think I see someone coming this way."
