It's a little surprising; normally she is permitted to enter random forests of her own will. But not that much.
She starts walking, looking for whatever inane plot she will be required to participate in/thwart this time.
Eventually she sees a cottage. She makes for that--random houses in the woods are prime weird shit locales.
She knocks on the door. "Excuse me! I don't know what's going on here but I'd rather get it over with sooner rather than later so I can go home!"
"The sex demons need sex energy to...well, not to live, exactly, but it's food to them. For them, sleeping with someone has about the same emotional meaning that...wait, food envassals you. Well, it has the emotional meaning that having someone make you a sandwich has for mortals. A really good sandwich, if it's really good sex."
"Oh. ...Are these common? Should I ask you to order me not to have sex with any sex demons?"
"Probably not, no. Is it ever going to be a really good idea to have sex with a sex demon?"
"Oh. Okay, if that's the best reason. Are they pretty easy to tell apart from other people?"
"Then I'm not sure the order would work very selectively unless you told me not to have sex at all, and then I'd have to find you or give someone else mastery over me to get it reversed, down the line when I'm feeling better."
"And at that point we're back to you can let me know if someone propositions you so I can tell them it's not okay. They're not going to mojo you off the street, anyway--in all the cases I've heard of it happening, the victim was lured into a position where no one else would notice the incubus or succubus being supernaturally sexy."
"Thaaat seems like a bad idea for a number of reasons. Their magic is a bloodline thing--half fey can do it sometimes, but plain humans just can't, and I'm not confident you count. Also, we would have to find a fairy to teach it to you, and most of them are, again, snobs. We'd have to find a way to make it worth their while, which would be...difficult. And I can't be sure that one wouldn't be offended by the fact that your kind of fairy uses the same word as them when you're so different," Overbite says, wincing.
"I can just say I'm a leaflet," suggests Promise. "That's the kind I am. But if it's safer to learn the kind mortals use I'm just as happy to try that."
