You've beaten the 2 on 2 format to death in the first part of two part scenes. Really you're doing TOO many two part scenes, other may disagree. But I digress.
I feel that some of the 1st parts should be 3(m) on 2(f). that way you don't have about 1/2 the scene with one of the females essentially doing NOTHING except cramming her head near the action, which just makes it even MORE difficult for the males to fuck hard, fast, or DEEP. (who am I kidding, they wouldn't anyway if there wasn't an extra head in the way or not) Just bogs down the progression in a scene, too many pull-outs to put in the other girls mouth. Every 30sec or less, seriously. Go back, watch with a timer.
Instead, if you had a 3 on 2, one girl could be getting DAP'd while the other still getting fucked in her ass/throat/whatever. And if you want to keep the focus mainly on the one getting DAP'd, that's more than fine. You don't ALWAYS have to have both females getting fucked in fame at the same time. Actually would be better off that way IMO. And at least the other won't be sitting around for 10min or so doing next to nothing "cooling off".
Just food for thought, cuz it doesn't seem you've been giving your "thoughts" too much "food" recently. No offense. It's just too easy to get complacent after extended periods of success, that's all.
