He does with his cousin what he saw in a porn movie
As they say, kids imitate what they see. And it may be real, that confirms that we behave like primates. That they do what their instinct tells them is also fine and again confirms that we are animals of instinct. The truth is that this young girl, after watching dirty things, does with her cousin what she saw in a very horny porn movie. She naked on top of him, starts giving him a cock suck. Once he sees that she is hard, he doesn’t stop until he is ready to start penetrating her pussy and making her enjoy herself. Because she is her cousin and she deserves it.
