Cord - 6.3★

On a post-apocalyptic world of never-ending winter, a sparse cast of outsiders live underground. Due to their unsanitary conditions, sexual contact has become dangerous. Masturbation has become the paradigm of sexual experience and an array of low-tech devices with this purpose has come into existence. In this bleak reality, Czuperski (a dealer of such machines) and Tania (a sex addict) make a deal: she will allow him to experiment new devices on her body in exchange of pleasure. Soon however, their relationship goes out of control.
