The dim light from the streetlamp casts an eerie glow through the window, illuminating the silhouette of a figure leaning against the wall, their arm moving in a steady, purposeful motion. The sound of flesh on flesh fills the room, punctuated only by the occasional car passing by outside. The figure's breath hitches, their body tensing as they reach their climax, their load spilling onto the floor, unseen and unnoticed.
