Anastasia is sitting up with her arms bound together behind her back, with Edith sandwiched in the middle. Edith is in perfect position to tickle Anastasia's vulnerable ribs, pits, and neck. Anastasia giggles and squirms but there is nowhere for her to go. Partway through the clip I jump in to tickle Anastasia's feet (and Edith's too!) with fingers and a brush. Edith happily continues probing Anastasia's sides and looks gleeful as the reactions become more intense.
