In the dim light of the closet, siblings lost in religious fervor find solace in each other's bodies. Their breaths synchronize as they undress each other, the cool air prickling their skin. The brother's fingers trace the curves of his sister's body, lingering on her hips and thighs. She arches into his touch, her pussy throbbing with need. He slips a finger inside her, then another, pumping in and out as she grinds against his hand. She returns the favor, wrapping her hand around his cock and stroking it until it's rock hard. They stand facing each other, their bodies pressed together, as he guides his cock into her. They move slowly at first, then faster, their moans muffled by the closet walls as they chase their orgasm, their bodies slick with sweat and their hearts pounding with the fear of being caught.
