I have Jamie in a trance and have her lift her feet up in to the air. I suggest to her that rubbing her feet together makes her cum. At the snap of my fingers, there's a field between her feet. I tease her a bit, before making the field go away. She goes back to excitedly rubbing her feet. The forcefield comes back, and then I have her realize that the forcefield is coming from her panties. She gets rid of her panties, and goes back to rubbing her feet. I leave her with her feet spread, and trigger pleasure and then suggest to her that she's having really good sex.
