Luckily for Elise, Lilith had more than one way to challenge herself.  Seeing how many times she could bring a human to orgasm before they passed out was one of them, before she killed them of course.  The most she had managed was ten times, and the man had been surprisingly strong before she had gotten a hold of him.  He'd begged for her to end his life at climax number 5, and had become insane with pleasure by the 8th one as she tore his mind apart before giving him exactly what he had desired.  He died screaming in ecstasy, although by then his voice had become so hoarse and gravelly it had been hard to tell if he was growling or moaning for anyone else that might have heard his dying screams.  Elise however, she didn't seem to be afraid to flaunt her stuff.  "A boob job?  Oh, you naughty girl you."  Lilith purred, coming out of her mental reverie as she cupped the woman's breasts, squeezing them with no small amount of skill as she smelled rather than saw the woman's clear arousal as it dripped down her legs.  Letting her drop the robe to the ground, the succubus queen let her tail move away from Elise's neck before it pierced the demon's own exposed clit, making her quiver and tremble as she used a variation of her own venom upon herself.  Pulling her stinger out of her engorged clit a moment later,  Lilith took a step back, then another, still shaking before she threw her hands out to either side of her body and groaned loudly as a dick erupted from above her perfectly formed pussy.  It was thick and big, bigger than a normal man's cock, but not nearly as big as an incubus's own either.  Even so, it would be more than Elise had had in her yet.  "Get down on your knees and suck me, mortal.  Do a good enough job and I might just use it on you."
