She's swallowing dick at the glory hole.

This little video is from Barbi Cummings, whose web site is all about getting fucked by black guys and taking internal cumshots, with the pretense of getting pregnant. Watching the trailer, the premise might get slightly offensive to some sensibilities, but there are some gem moments, and this is one of them. Barbi has a friend that goes to an adult bookstore with her to indulge in a gloryhole, and after way too much giggling (which this clip doesn't have), her friend goes right to deep throating a very long cock. Her technique is admirable, and erection-inspiring.
