The steam from the shower billows out, creating an erotic fog that clings to the air. Inside, a young woman stands, her body slick with soap, her hand moving rhythmically between her legs. Outside, her brother watches, his heart pounding in his chest. His eyes roam over her body, lingering on the curve of her ass, the swell of her breasts. He can't help but imagine joining her, feeling her wet, soapy skin against his own. His hand moves faster, his breath coming in short gasps as he watches her pleasure, his own building to a fever pitch.
