The air in the closet is thick with the scent of sweat and piety as the siblings struggle to maintain their composure. The older brother's cock tents his pants, betraying his arousal, while his sister's nipples pebble against her modest blouse. Their eyes lock, and the world outside fades away. With a shaky hand, she reaches for his belt, her knuckles brushing against his hardness. He groans softly, his own hand cupping her mound through her panties. Their movements are hesitant at first, but soon they're lost in a frenzy of forbidden passion. Clothes are shed, and they come together, their bodies slick with sweat and desire as they fuck with the intensity of a thousand sermons preached.
