Jonathon has found a new toy, and he believes he has a way to program it so that it will measure a woman's arousal. When he catches Erica ogling a group of male models across the street from where they are having dinner, he decides to bring her in on his little experiment. If she can control herself and her body's responses while sitting through a male underwear fashion show, she'll be free to spend the rest of her vacation exactly how she wants. Eager to please and a little tipsy, Jen boasts that the challenge will be easy, but Robert knows her too well. For each threshold you pass on the thermometer, he adds, you take off a piece of clothing right there and then. Erica agrees, secretly turned on by such high stakes, but she knows that if she isn't careful, arousal and humiliation will form a compounding feedback loop that will leave her the center of an impromptu exhibition more than sufficient to steal the show.
