Like you

You open the door to your room and see your original body in it. He looks at you and asks "Hey Kate. What's up ?" "Uhm nothing ... just checking if you were here." You answer, noticing your new high voice. Your body just acted like you. You go back into the kitchen to take a closer look at the calculator. Back on the 'switch'-button you noticed a couple of fields that you hadn't payed attention before. First there was a field where you could write the name of the person you wanted to swap with, after not writing something in it there just stood 'nearest person'. Then there was another field where you could choose 'normal swap' or 'brainwash swap'. Like you noticed before it stood on 'brainwash swap'. There were the same buttons next to the 'morph'-button. Plus there was a 'body part' section to morph.

Knowing your body was ok you now could relax as somebody else. Since you two were alone at home you can't think of any reason switching to another body. You were alone at home with only your original body. After all you could learn a bit about your sister's life and with that a girl's life in general. You had to admit that she was a beautiful looking girl. She also was one of the hottest and most popular girls in her class. You two liked each other and never argued.

You go up to your sister's room and hide the calculator. You weren't in here for years (when you ever were. You didn't knew). She had a gigantic wardrobe with all kind of clothes and a big bed. In the edge of her room was a desk with some school books laying on it. It was a very clean room. Your new room was one floor higher in your house so your old body would never even come near here. Your room now was on the 3. floor. Your parents and 'brother' had their rooms on the 2. floor. The complete 3. floor was yours and there was no floor above you. There was a big bath with a shower and a bathtub. Then there was your room and your own leisure room.
