Do you want to see an intensive session, well here is the first part of Natalie's ordeal!
She is wrapped face down on the table (she can't move at all), and we start tickling her armpits!

She is super sensitive, and mostly with the electric toothbrush but she is tickled also with hands and feather.

Then we move to her feet with a close up (you can see her face as well), she is drenched in sweat ...
Most dreadful, at the end of the session, I tell her that it's only half of the session, poor Natalie!
