Wait, what the hell is going on in this picture?

Would it work on a male?

I decided to do a bit of math for fun, and this is what I got for determining what will happen to the likely poor butler here:
 
I used both Octavia/Vinyl pics (the start-up and the afterglow boom) to determine how much bust size a pone gains from one, by measuring the number of pixels first for Octavia’s torso, then for her starting and ending bust size. And taking the two sizes and dividing them, it turns out the size increase is about 2.55 times bigger in bust size per stick.
 
Now, with the belt of dynamite attached to the butler here, if it stays as equal in number in the back as it is up front, there are a total of about 18 sticks attached to him. And let us assume that the first one goes to 2.55 inches to kick off the chain of breast expansion that the mare desires, with each one exponentially adding to their bust size by that amount.
 
As such, I calculate that this butler will end up with a bust size of 20,783,718 inches in size. Or about 1,731,976 and a half feet in size. So as such, I’d advise against pressing that button unless you want to be flooded in bust within a few seconds before you can escape.

oh my incoming breast expansion by explosive in…
