Part 2
"Hello! Could you make a body swap caption about two sisters that are complete opposites? Thanks a lot in advance! 
The older one is tough and muscular, and she is always picking on the younger who is shy and girly.
But one day, the younger sister decides that she's had enough and switches bodies with the older one."
