Two naive sisters, bound by religious fervor, find themselves alone with their virile stepbrother. As they pray, their eyes drift to his bulge, igniting forbidden desires. They try to resist, but the taboo allure proves too strong. Michelle, the elder, tentatively reaches out, tracing the outline of his cock through his pants. Her sister, Maria, watches, her own breath hitching as Michelle unzips his pants, revealing his throbbing member. They take turns exploring his hardness, their fingers sticky with pre-cum, their hearts pounding with sinful excitement.
