I'd count Sasha Knox's first American Bukkake as a gokkun, since she swallowed it all,before there was American Gokkun. I think it was the hottest one.
Her actual gokkun scene was ruined by the dog barking theme. If she was just her cum craving self it would have been the best.
I'd say Bailey Brooks was really hot in her scene. Chelsie Rae and Keeani were great too. And I can't leave out Hailey Young. Those ones stand out for me.
