The succubus smiled as she withdrew her fingers, feeling Lyla's moisture.  "Ah, but your body is definitely saying yes," she teased as she raised her tail, the tip penetrating between Lyla's folds.  "But perhaps I can make you a deal.  If you still say no, I'll take your friend instead.  Then, if you still refuse, I'll leave you be."  She paused for a moment before adding, "But I think we both know you're smart enough to figure out that I won't make it easy for you to say no," licking the elf's ear as she finished speaking.
