The succubus gave Niarra a smile.  "Oh... I have a feeling you'll be fun to break in.  As for you, dear," she said, turning to Lyla, "I see you're already thinking the right way.  Just let go of your defiance.  After all, there's no way the two of you could get out of here and get past me."  She smiled again, considering, as she reached into a small bag and pulled out several long coils of rope, as well as a few vials of milky pink liquid.  "I'll give both of you a choice now.  Agree to submit, and I promise after I claim you, you'll come to no harm, and I'll leave you alone.  Refuse, and you'll see what kinds of torment I can devise to make you submit."
