These are two twin succubus demons, twins in that they both have the same idea, to take you beyond your limits. To see how far they can push you before you are begging them to stop. Trust me, they know what pleases you, be it mental or physical. And they don't mind doing whatever it takes because they feed off the spark that happens at the point of orgasm. So if you don't, they don't feed. It's a win win situation.
