Two siblings, bound by religious upbringing, grapple with their forbidden desires. The brother's cock tenting his pants, the sister's nipples hard against her blouse, they're a powder keg of sexual tension. They try to resist, but their bodies betray them. They strip, their nakedness a sinful delight. The sister's fingers find her wet pussy, her brother's cock hardens at the sight. He joins her, his fingers replacing hers, his tongue tasting her. She returns the favor, her mouth tight around his cock. They fuck, their bodies entwined, their moans hushed by religious guilt.
