Fancy an outdoor quickie? It’s a beautiful day. Come take a rest with me in the park. Just enjoy this moment and enjoy the fresh air. But be careful, little slave. If you stare at my feet for too long, you might find yourself slipping into trance right here on this park bench. Why, anyone walking past could see the way your body is going limp, the way your head is tilting to the side. But they wouldn’t know what’s happening to your brain. They wouldn’t know that it’s my feet that are controlling you. Or would they?
