Stephanie Swift, alone in the sterile, fluorescent-lit corridors of an abandoned metro station, finds herself drawn to the forbidden thrill of self-pleasure in the public space. She leans against the cold, tiled wall, hiking up her skirt to expose her lacy panties. Her fingers dip beneath the fabric, stroking her wet slit, as she imagines the risk of discovery heightening her arousal. The echo of her own breath and the distant hum of unseen trains fill the air as she loses herself in her taboo desire.
