Lucas's heart races as he watches the neighbor through the window, her silhouette dancing on the shower wall. He can't hear her, but he imagines her cries of pleasure, her hand sliding down her body, fingers delving into her wet pussy. His own hand moves faster, tighter, his breath coming in ragged gasps. He's right there, on the verge, but the elusive orgasm remains just out of reach. His body tenses, his cock throbbing, but no relief comes. He collapses back onto the bed, defeated, his hand sticky with precum, his mind filled with unfulfilled fantasies.
