Religious constraints met with sinful copulation

In a cramped, dimly lit room, a brother and sister, driven by curiosity and hormones, begin to masturbate. She slides her panties aside, exposing her glistening pussy to his eager gaze. He strokes his hard cock, pre-cum leaking as he watches her fingers dance over her clit. Their moans grow louder, breaths ragged, until they're interrupted by a knock at the door. They frantically dress, leaving their desire unsatisfied.
