When it comes to incest between siblings, most people think of youthful indiscretions. But this brother and sister share a special bond. The brother is 51 years old, the sister 45. After a year of divorce, the sister has no boyfriend and no sexual partner. Returning to her family home, she begins to see her brother as a man. She can't help but stare at his naked body as he changes after a bath, her emotions growing uncontrollable. The urge to sleep with her older brother, to hold him, to bathe together and have sex becomes overwhelming. Unable to restrain herself any longer, the sister starts provoking him—flashing her panties, exposing her breasts—then takes more aggressive action. In the bathroom, she boldly reveals her naked body and pressures him into sex. At last, this middle-aged sibling pair crosses the line into incest.
