Having a twin brother now was actually boring especially if he looked and acted exactly like you. An older brother on the other hand would be fun. But not make the other you older.
You then point the wand at yourself and tell it "Make me younger"
"Te-he I think you being little is more fun then being the same as me" said your clone/twin
You feel as if your body starts to retract into your body as your body begins to shrink. You could feel any body hair start to disapear as you saw your twin grow before your eyes when in reality you were getting smaller. You expected your clothes to grow loose on you but were changing along with you. Which made you glad as you didnt want to be naked in your younger body.
"I wonder how young Ill get?" you said as you realized you never were specific on age.
You continue to get younger until you were...
