As promised, I have made a videoclip with highlights of a recent 45-minute session (20 minutes preps, 25 minutes on camera):-

There were two constraints on my time – needing to go work afterwards and having only 30 minutes of high quality video available on my camera.
For my next video I will film the tail-end (pardon the pun) of a longer session.
To be honest, I felt a bit self-conscious making this. I was not embarrassed at all as I've made plenty of other clips before and enjoy doing so, but I was conscious of the fact that aspects of the session might look forced or fake.
And in editing it I was aware that there's not much excitement to be found in watching someone from behind grind his crotch into a pillow LOL.
