Her brother’s cock makes her pussy slimy

Sometimes we see food and it makes us hungry, everyone knows what happens when you cross the street at the junk food place and you forget that you just ate because you already have a man again. But other things are more biological and have nothing to do with the manipulation of smells, like this young girl who sees her brother’s cock and that makes her pussy slobbery. She literally gets very excited and can’t stop thinking about putting it in her mouth, which she obviously does and then ends up enjoying an incestuous fuck with the guy.
