The chick has no problem taking it in her mouth and sucking it, she cheats on her husband knowingly. If she needs to swallow, she swallows, if she needs to expose her buns to passing motorists, she'll do that too. The blonde acts like a bitch, ready to do any order of her lover or master.
The brown-haired girl is not an ordinary modest girl. So she showed off her skills in front of her lover. Apparently she has a lot of experience.
