I've been messing with my step sister Ally for a while now, she knows that Im just messing with her (at least most of the time) but today I think it really started to piss her off....Today while we were hanging out, I was doing my usual little things here and there, but by the end of the day she had enough.....she stood up and started cussing me out! Telling me off here and there...but while she was screaming and yelling....I noticed a huge wet spot on her crotch....she got so angry she PISSED her pants! Ive never seen anything like this before....Ive seen people wet themselves from laughing.....or being scared......bet never lose control of their bladder from anger!!! I might keep messing with her.....I cant lie and say I didn't think it was a little interesting to see....
