What happens when betrayal isn’t a mistake, but a shared desire? George is a mature and confident man. Mark is his younger and trusted friend. Their wives, Barbara and Samantha, are beautiful, curious, and complicit. One evening, George makes an unusual request: he wants to watch his wife give herself to another man. Not out of jealousy or humiliation, but to see her differently, to rediscover her. Mark accepts. Samantha watches. And Barbara lets herself go. Consent to Anal Sin is an elegant and intense story of erotic complicity, where control and surrender blur. A cinematic experience of lust, voyeurism, and shared perversion. No one is forced. Everyone is aware. And when the game begins, the rules are rewritten.
