From 'Narcissus in Chains'

From the Anita Blake book "Narcissus in Chains', by Laurell K. Hamilton. Around p. 171.

Anita has become a sort of cross between a werebeast and a succubus as a result of a magical union with a vampire and a werewolf. She finds herself victim to an uncontrollable need to feed on others' sexual energy, which she doesn't like much, except when she's doing it.

In this scene, her (willing) victim is Nathaniel, a wereleopard. He really isn't that much bigger than her, but by the time I remembered, I was afraid attempting to shrink him might mess up the picture. In the background is Jason, a werewolf, who's been told to watch her in case she hurts Nathaniel (in a way he doesn't like).
