Behind the scenes/on-screen tying

Hi,
I am looking for videos with good behind the scene content. I mean everything that happens up till the moment the tickling begins or after the tickling is done. I have two specific requests:
1. Please advise what titles to look at
2. I once bumped into a clips where a girl was taking a selfie in the stocks before tickling started. Anyone knows what it could be?

French Tickling, Tickle Abuse & UK Tickling have a lot of cool pre and post-tickling footage in their videos. I'd recommend them highly!
