BSD - Body Swap Device

The Next Body is...

You notice a small family which has a mother, a father, a boy around your age, and a younger girl, who looks about 8 or 9. You decide you'll enter the body of one of these family members for the minute, and board the train they are boarding. You begin to slowly follow them until they stop in front of the next train screens, trying to find the right platform. (If you don't know what I mean by 'next train screens', look at the picture above.) You blast yourself with the BSD, feeling the same wave of warmth you felt before you switched with Amy. You aim the device in their direction and press the button. Your eyesight goes blurry once again and you wake up to find yourself standing slightly shorter than usual, with a tall woman stood next to you - the mother. You looked down and saw the boy's clothes. You had swapped again! You turned around to see your body buying a train ticket to the next town along, completely oblivious to the fact its actual brain was in a 14-year-old's body. You looked down at the boy's phone and acted like him. The wave of information hit you again - your name was Curtis, you were 15 and lived in the outskirts north of the city, near the airport. Your sister was called Jo, your mother was called Kimberley and your father was called Lawrence. Usually, despite whichever person you take over, you still find women beautiful, no matter the relevance to the body you're in. You knew you should be finding Kimberley beautiful, but you just couldn't. You walked with your family to the platform the train would be departing from. You boarded the train and found your seat. You looked over to the seats across the aisle from you, and your eyes fix on a boy, probably about 17. Thoughts began to enter your head: "He is so hot! Wait, did I just think that? Is this boy gay and his body has changed my way of thinking?" Your mind began to scramble everywhere, thoughts about the boy mixed with the fact you were temporarily gay. You had no idea what to do. Now you were on the train, you decided to swap again. You pull out the BSD, only for your mother, who was sat next to you, to notice. "What's that, Curtis?" You panic, quickly say "Nothing!" And blast yourself and the boy across the aisle.
       You wake up as a 17-year-old called Sean, and now you were travelling facing backwards instead of facing forwards like, what's his name? You notice that a boy slightly younger than you keeps staring at you. You ignore it and your eyes divert to what you assume is his mother next to him. Thoughts began to enter your head again, this time cisgender. "She is so hot!" you began to think. You quickly look away as the boy notices and look out of the window. An announcement comes across the tannoy; "Ladies and gentlemen, we have now entered Scotland! The next station is Edinburgh Waverley where we'll be arriving in the next 10 minutes. If you're leaving here please get ready to alight now. This train is for Glasgow Central." Your dad pipes up; "Right then, lets get our stuff packed up." You quickly decide you want to stay on the train. "I'm just going to pop to the toilet before we get off." You say to your parents. You walk down the train, BSD in hand, this body already zapped ready for a quick change. You look out the window to see Platform 11 of Edinburgh Waverley come parallel with the train. "Shit." you whisper. "I've gotta be quick." You quickly point the BSD in a random direction and you enter the body of...
