Hidden behind the heavy velvet curtain, the sisters whisper their sins to their brother, who listens intently, his cock growing hard at the lewd confessions. The older sister, her voice barely above a whisper, guides his hand between her legs, urging him to feel the dampness of her arousal. As he tentatively touches her slick folds, she moans, her body arching towards his. The younger sister watches, her own curiosity piqued, as their brother's fingers delve deeper, bringing their older sister to the brink of orgasm. Envious, she joins in, their bodies entwined in a taboo dance of lust and redemption.
