Lucky for the guy - now he's gone from a wanker to a stallion. She, as a woman, appreciated his dignity, and as a bitch, she couldn't resist the temptation to take his pepper in her mouth. Now he would be spanking her mama every day, and she would be taking his cum in her cheek. Happy day!
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!
