The distance between older sister and younger brother that should never be crossed quietly collapses.When he happens to see his sister urinating in the bathroom, their relationship becomes strained in an instant, a gap is created, and the atmosphere changes -- things quickly accelerate from here.The suppressed emotions come undone, and impulse comes forward rather than reason.A step you should be able to take back, but before you know it, it's a step you can't take back.That feeling of not being able to go against the flow.The more you try to stop it, the stronger it actually becomes.The facial expressions, distance, and air temperature change with each stage.That is incest.
