Seeing that the guy records it on camera - her girlfriend tries even harder. In addition, she wants to look even prettier - she fixes her hair, makes eyes, smiles. Knowing that the guy will show this video to his friends, she wants to impress them as best she can. Female logic!
I love the Blacked videos. It's always a black guy with a big gun and usually a blonde girl. Movies with a story line and with a girl who most of the time is moaning from the fact that she enters the large machine of a dark-skinned partner.
