In a household bound by religious fervor, two sisters find solace in the forbidden. Their father, a stern man, has instilled in them a fear of sin, but their bodies betray them, yearning for the touch of their brother's cock. They sneak into his room at night, their hearts pounding as they watch him sleep, his cock tenting the sheets. One night, they can't resist any longer. They strip him bare, their eyes wide with wonder and fear as they take in his massive, untouched cock. They lick it, suck it, and finally, one by one, they lower themselves onto it, their tight, virgin pussies stretching to accommodate his size. They ride him slowly, their bodies slick with sweat and sin, their moans muffled by their hands. In the aftermath, they pray for forgiveness, but their bodies yearn for more, their sin now a sweet addiction.
