I think all the better points have been made.
The shooting was a bit shaky. Having to constantly 're-center' the action with my eyes makes viewing a bit tiring.
A bit too much hand on the lower dick area. Yes, you did give your reasons. Just watching it, I could 'feel' the hand on my dick as I watched it. I know my lower dick likes some attention, too. Doesn't have to be the DT way. Licking around the base always feels great. Using your hand as a 'baseplate' works as well, vs using the way you did there. Each guy is different, though.
Other than that, not bad at all. Oh, yes. By all means, keep sucking afterwards. Even if you're not a swallower, that continuous action is heavenly. Shit, go as long as you can, until I tap out and nudge you off of it. Even then, steal 2-3 more slow bobs before letting go.
