"You mustn't move!" their father commands, but the siblings can't help but shift in their cramped hiding spot, their bodies pressing together in ways that send jolts of electricity through them. The sister's breath hitches as her brother's hardness digs into her thigh, while he swallows hard, trying to ignore the way her breasts press against his chest. Their eyes meet, and the spark of lust is undeniable. They try to distract themselves with prayer, but their bodies have minds of their own, their hearts pounding with desire. As their father's footsteps fade away, they're left alone with their thoughts, and the temptation to give in to their taboo longing becomes almost unbearable.
