8:57 video
an intro you can have a scene where you and Liv are chillin on the bed and you talk about the worker that you both like to tease since you both catch him staring at your feet all the time. It's well known that he has a huge foot tickling fetish that he's been trying to hide.. So you have a surprise for Liv. You pull out the toy and show Liv how you were able to shrink him so you both can have some fun with him. Maybe make him your little tickle toy.
Then just shoot 2 scenes with both of you tickle each other's feet using the techniques in the gif while tickling the toy every now and then. You let Liv go first. So she can tickle you for 3 to 4 minutes. Then shoot another scene where you switch positions and you tickle Liv for the second half of the video. You both can add any dialogue you like that goes with the toy your using. Fireman Just say something fun that goes the trade
