Ronica pees in her pants in this video, but surprisingly, the pants she is wearing barely show the wetness.

Imagine peeing your pants, but no one is able to tell.  That is almost what happens in this scene with Ronica.  She tries peeing in her pants, and indeed, she pees a lot, but the pants don’t really show the wetness.  Most of the pee runs down her legs, and eventually the pants do show a little bit of dampness, but overall do a good job concealing here accident as it happens.
