I took a punt on Huge Cock Junkies 3 - great DVD. 4 scenes, all anal, all very hot. Scene 2 with Kristyna marginally the pick, although Kia Winston in scene 3 takes the hardest pounding from Joachim, very strong anal workout.

I quite like the settings here - lots of converted loft spaces, bit different from the standard bedroom sets you get in this type of porn. It could use a bit of chat with the girls before the scenes to get their personalities across (or even better, some sort of scene scenarios) but in so far as "gonzo" porn goes this can't really be faulted. Great energetic sex, guys and girls all really into it, little or no throat grabbing or unpleasant stuff, just quality porn.
Will keep my eye out for future Combat Zone releases for sure.
