Watch Sosha as she has an accident in her diaper and disposes of the evidence in this video.
Through several past experiences, Sosha has learned that it is best if she wears a diaper when she is in the car, just in case. Driving through the forest, wearing a diaper turns out to be a good idea. Needing to pee, and with no where to stop, she wets her diaper.
Not wanting to wear a diaper for the rest of the drive, or risk leaking on the car seat, Sosha stops at a secluded location. Making sure no one is around, she takes of the saturated diaper and drives off, leaving the used diaper behind.
