I think the husband knows that his wife is filming regularly. Look at that - she has a microphone on her left shoulder and is connected to her phone. He's probably jerking off at home when he hears his Asian wife negotiating with the next guy on the stick. To get those breasts moistened with cum - I'd get in line, too! Look how her buns have risen on those jerks - there's a lot to take in!
The girl is pretty, young and fresh enough, so no wonder this man got so turned on looking at her. And he's lucky she turned out to be loverly enough.
