I know you have been playing around in my room, little brother. Did you think I would not notice all those missing bras and panties? I definitely did, but I wonder if you have you noticed any personal changes of your own lately. Maybe certain parts of your body getting softer and certain other parts getting... smaller? HA!

I have been slipping a little special something into your system that will make all those stolen panties fit much better. Your butt is going to be getting fatter but that bulge is going to be getting even tiner. Do you still have a crush on your big sister even though I made your dick so little?
