Verbal teasing, to me, is absolutely integral to videos, and also greatly enhances private sessions.
If I were the King of all future video productions, I'd require that every video include talking during sessions, of the nature:
• Do you like this? Tell me you like it. Tell me you love it. You didn't sound sincere.
• Which do you prefer, here? Or here? I don't think we got a good enough test, let's try again.
• Let's play a no reaction contest. Can you have no reaction to this? How about no reaction to this other style?
• I've always wondered: One hand faster? Or two hands slower? Which is worse? Wait, let's see if location matters. How about here?
There can be endless variations, of course, but why wouldn't every video have some kind of verbal teasing? Seems to me, it's usually just that no one's thought about it.
