Julia, her heart pounding, gently pushes Jake's stiff cock inside her. Jake, torn between duty and desire, grabs her ass, pulling her closer. They move cautiously, their breaths syncing, as they give in to their taboo lust. The closet fills with their soft moans and the scent of sex. Julia's pussy clenches around Jake's cock, drawing him deeper, as they approach a shared climax, only to be interrupted by their father's voice, sending them tumbling into post-coital shame.
