Mary searched through the bag. She found something and pulled it out, it was a black t shirt with a blue logo on it. Mary looked down and found a pair of blue jeans, she then pulled out some black chuck taylors.
"Mm, looks like something a little boy would wear. Should I or shouldn't I?" "Bugger it, yes."
Mary took off all her clothes, including underwear, luckily there was a pair. Mary pulled the t shirt down, it had a bit of trouble fitting at first but it got down. Mary then grabbed the jeans and pulled them up, once again, they were a pain to fit at first but they went up. Finally Mary put on some small socks and put the shoes on, they were way too small.
All of a sudden, Mary felt herself shrink slightly, her breasts were being sucked it, her hair shortened, her feet shrunk and her genitals changed. "Holy crap." Said Mary not used to the new voice.
She was now a young boy, maybe ten years old
