It's a cage, of course. She just put her boyfriend in the cage before the black guys show up and start working on her. I've written about this many times before. This is increasingly common and popular. The cage really super charges the sexual excitement because the white boyfriend watches some black guys totally take and use his girlfriend, right in front of his eyes, and he can't do anything about it. He desperately wants to masturbate while this is all happing in front of him, his girlfriend moaning and writhing, screaming with one orgasm after another, and he is so excited, but he can't touch himself and he can't cum. Of course, at the end of her session with black men, she will remove the cage and then he can masturbate on his back while she sits on his face and let's him eat out of her all of the cum that a bunch of black guys filled her up with. It is an awesome scene. Everyone gets super stimulated, especially the white girl and black guys.

What the fuck is that thing? Weirdos
