Any chick loves it when her pussy is licked. And this brunette found a loose tongue from her brother. Naturally, for such services she had to pay the full price - to take in her mouth and let her slit put on his dick. I can only see that she enjoyed it. And to feel like an actress being filmed and licking at the sight of her vagina and cum on her lips - she just enjoys it.
An Asian girl knows that the man is in charge of the house. And that's why even the lovers must be pleasured with all respect and diligence. Of course, she lets them use her body as they want and even cum in her wet pussy. And for gentle sex and warm attitude from their side - I think she can count on all the time.
I'd try that with Laura.
