Lilith knew something was up when she started to see Elise's stomach bloat and distend.  Something was growing in her gut.  She chuckled to herself, not worried in the least as she pulled out of the woman for a moment before turning her around so that she was facing her new mistress before slipping into her again.  She had other plans for this little harlot.  She continued to pound into the woman, her legs wrapped tightly around the demon's body, the succubus queen let her tail find a spot right at the top of the woman's spinal column before piercing the flesh and the spine itself, pumping her full of her aphrodisiac venom which would set every nerve in Elise's body to overload.  Not that she needed any help, and with what Labyrinth had done to her, Lilith knew it wouldn't be long before Elise was no more.  She'd be well out of the way before it happened however as she groaned in bliss, her cock soon expanding right before she cried out in pleasure as she emptied her seed into Elise's womb, saturating the growing demon within her at the same time.
