11pm? The OP was the 10th guy to pound her that day/night. I don't know how these girls maintain
any a level of enthusiasm, fake or otherwise. The routine carries them through, till they can finally go to bed to sleep. In most cases it should be enough for the monger to just be aware he is naked in a room with a beautiful young woman who is giving him permission to do whatever. Forget about Meryl Streep quality acting, just be glad your present with a cutie who can stand you for 45 minutes.
