Amidst the gritty streets of Detroit, secretive masturbation sessions unfold, unknowingly recorded by hidden cameras. A man in a worn-out t-shirt rhythmically jerks off, his hand slick with precum, his breath hitching as he tries to stay quiet. Across town, a woman in a tight dress slips her hand under her skirt, her fingers rubbing her clit, her hips moving in sync with her touch. The city's dark secrets laid bare, one stroke at a time.
