This one would be like a foot tickle where foot model would have a sheet over her feet. Hands would slowly peel the sheet back revealing the soles of her feet. Then just walk the nails from toes the ball of the foot. Mostly one at a time then from time to time do both at the same time. Every now and then foot model would pull her feet away to stop the tickling and tickler would grab her ankles and slowly pull feet back into frame and repeat the tickling.
