Lilith may not be as voloptuous as her sister, Morrigan, but that's because people aren't looking in the right spot. She's still a succubus and she still very much knows how to be sensual, but she also needs to be put in the right mood, so earn her trust with some flirting because she doesn't like being taken by force. Try to capture her in her default outfit to get the most enjoyment from admiring her curves and tie her in a tight shibari to emphasize her nicest and most sensitive spot: her butt. Once she's tied, a few squeezes of it will have her purring happily for quite a long time. For her gag, give her a ballgag topped with an OTN to cover her face and draw attention to her eyes. Foam her legs and exposed back for even more fun, too.
