I cannot possibly combat these girls, I must submit and serve their desires!

You reluctantly come to the conclusion that no matter what you do, you will always end up on your knees pleasing your mistresses feet. The succubus, who said her name was Rebecca looked puzzled while you contemplated your quest. Finally, you decided to tell Rebecca about yourself, your quest, and your new 'quest'. Her eyes and her smile seemed to grow as you told her that you think your place is at the Monster Queen's feet. As you finish explaining to Rebecca, you drop to your knees "Please Mistress, let me serve you the same way I will come to serve the other monster girls!". Rebecca pulled out a map from behind her, you have no idea where it came from but decided not to question it "This is a map of all our bases, hideouts and ambush routes. I will give it to you if you kiss my foot one more time". She sat down on the bed, crossed her legs and extended her right foot to in front of your face, which smelled a bit funny. "Once you have kissed my foot, you will be bound to serve us at your own 'free' will".

You hesitate, thinking one last time about whether submitting will be worth it, and whether she is bluffing. That map will be very useful if you do get your hands on it though, perhaps you could overpower her? Then you got a worrying feeling that you will just end up like how you already have when you tried to fight these girls. What do you do
