Sosha pees in her jeans after being forced to stand next to, and listen, to a river while desperate.
In this video Alisha records as Sosha is desperate to pee. There is no bathroom around and Sosha is standing next to a large river. The sound of the flowing water, combined with the sight of the rapids, is too much for Sosha. Unable to hold it she ends up peeing in her pants. Alisha then follows her with the camera, showing her wet jeans from behind.
