The Japanese girl squeaks, but obediently lets herself be pawed. These noises only encourage the guy to stick his dick in her mouth and make her suck him.

The father clearly raised his daughter - Dad is the main thing. You could always find support and encouragement from him. And to suck his cock is just a thank-you for having him. By pulling her on his cock, her father showed how much he trusts her and that secret will be with them now. And the chick did a great job - and daddy is happy and she's even closer to him now.
