Real twins' hardcore lesbian scat that we may never see again! The sister resists her sister's pooping with total disgust. The sisters share a lesbian kiss, the younger sister reluctantly accepts her sister's poop, they give each other an enema for the first time, they pee on each other and lick and clean each other's pussies, etc., all of these scenes are full of tension and firsts. The sister says, "Look! I ate natto (fermented soybeans) and my poop is all sticky! She says, "But if you eat that, your poop becomes so stinky!" Just watching the exchange between the two sisters is fascinating.
