Not exactly a pair of second lips it's more of the inner side of their cheeks. You know when we suck in our cheeks because it makes a funny looks on our face? Yeah it's the same concept as that but slightly different.
They have a huge gap between their front teeth and the rest of the teeth the gap is where the inner part of their cheek would go to close off access to the rest of their mouth
