. and hop towards the conquest of my address .. finally .. my shot tonight.Arrived at a small private house in the suburbs .. I ring .. a dog cries pu...hing two three .. probably a little dog. The door opens .. on a woman .. which is not the sixties and she was really 48. A thin face, thick black-rimmed glasses ..

We had to run a computer program that would transfer our essence into the other person's body simultaneously.

Eventually I was sliding in and out of my little sister with relative ease. I looked down and saw myself.
