yes…

Don’t worry, Rainbow Dash, accidents can happen to anyone. Once when I was at the doctor’s office the doctor was feeling my stomach when I was having a physical. Anyway, I started laughing and you can pretty much imagine the rest. I think I was around Scootaloo’s age when it happened.
 
Because I was laughing my mother thought that I was doing it deliberately. Luckily I did not get spanked or end up in diapers but my mother told me how embarrassed she was, and that I was too old to be doing this, and so on. She also said that she was going to stop at the store to buy diapers for me. Fortunately she did not actually do it.
 
I was born prematurely and there were some complications. As a result, I’m still ticklish in that area today in my early forties. The best I can remember this is the only time this happened in a doctor’s office after I was a baby or toddler, but every time I see the doctor I worry that something like this could happen again, especially since I still cannot (at least not reliably) cut the flow after it starts, even though I’m male instead of female.

it wauld be cool if it was in the movie

Eeeeeew gross!!!

I thought this disappeared, I guess that just happened when “questionable” was hidden rather than spoilered. Favorited immediately! She’s my favorite character to fetishize, and this is my number one fetish! Her outfit is cute too.

The reason to this happening is the Hitmarker pressing on Dash’s stomach

“Oh man, Dad’s gonna kill me.”

Feel better Dashie?

On the plus side Rainbow Dash, at least your random drug test will be cancelled.

@Riley Musseau

I asked my sister and she said barium is poisonous; for bladder examinations they have them drink iodine solutions.

Oh no, looks like someone couldn’t reach the potties in time!

She is undergoing urography. Basically, they made her drink barium, which is higly visible in x-rays.
