One day while you are fucking the slim younger sister in the toilet, the older one came in and caught the both of you. She gasped at the sight of you slamming your dick in her sister's tight little hole. She starts to push her sister off and argue that her little sister shouldn't steal her man. The older sister grabs your hard dick and start to suck you off obediently, "you belong to me, uncle." The younger sister kneels down and jumps in, "I know you prefer my tighter body, uncle."
