Something is deeply wrong here, and Kamryn's inward frustration grows as she once more finds herself lacking the mental tools to see how it works. This isn't like the tribesmen who wanted to fuck her and pretended they didn't. This isn't like the tribeswoman who got disgusted about Kamryn enjoying things she wouldn't enjoy. This is something else entirely that Kamryn has no reference frame for, but the shape of it is crystal clear.
"If you want to know what I want... I want you, I want everyone, free to act on their sexual urges. Free from, from reasons not to, free from things exactly like this, where someone, where your former lord forced you to build yourself a cage around your inner radiance I mean lust, to keep it trapped and-"
It occurs to Kamryn that she knows important facts that Lily doesn't, and explaining her own motivations probably ought to be secondary. She cuts herself off and starts over.
"The others, all four of them, the Tentacled work differently than we do. They're all telepathic and their food is a kind of psychic energy. When you're feeling sexual pleasure of any kind, a Tentacled can read that pleasure in your mind. It's like, lust is sunlight for them, they're blind without it, but when it shines in someone's mind it illuminates and warms and nourishes them. I'm what Eydow called a 'Lust-Esper' so I can see the same light they do and understand them more easily than most people. So what they want is, truly, for you to enjoy the sex you want. Even if they didn't know better, which they do, and only paid attention to the light inside you, well, that would be as opposite from what your former lord did wrong as a thing can get, even if it too would be a mistake."
