the cute niece who came to stay acts unexpectedly! after dinner, she jumps on my lap while i'm relaxing. her innocent bouncing ass makes me fully hard. with my wife nearby, i'm anxious, but she rubs against me and inserts my raw cock into her skirt. i manage to stop her, but the niece gives up and crawls into the bed for reverse night fucking. i can't stop her wild ride and creampie her.
