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!
Specifically in this case, the saying is true - you like to go for a ride like to pay for your trip. And it's not about the money, because hitchhikers do not like to pay money - well, she did not pay. The driver combined business with pleasure: he found some company for the road, and in doing so, he threw off his tension. Although, for those who have watched it to the end, it's clear that the girl was just tricked. Maybe this will teach her to pay for the services she uses, instead of trying to get freebies everywhere!
