One day, a huge pink door appears abandoned outside my home. While I inspect it, the building manager mistakes me for the person who dumped it and orders me to take it inside. Then its owner suddenly appears and claims it can instantly open onto any place I desire. I don't believe him until the door leads straight to the bathroom of the adult woman I have a crush on, then to the bedroom of another stunning woman. It really is a mysterious door that can take me anywhere—and turn every destination into an erotic encounter.
