The girl was stuck in a room with a perfect wall and an open hole, where she was being pleasured by an invisible lover

The girl hung from the wall, her perfect arms and legs sticking out of the hole. Her perfect fingers were busy with a camera, capturing every moment of her pleasure. The walls were white and smooth, but they had a certain texture that made them feel rough against her skin. She could hear the sound of a dildo being thrust into her tight hole, filling her up with pleasure. The only light in the room came from the open anus on the wall, casting a warm glow over everything. She was stuck there for hours on end, lost in pleasure as she watched herself being fucked by an invisible lover.
