After a quick costume change into a swimsuit that leaves her armpits and skinny ribs completely exposed, Mary is back for more tickling. This clip is mostly about playing with brushes, first a shaving brush, which drives her crazy with the slight prickliness of the bristles. After that, a fan shaped paintbrush with a mink tip, which sends her into frenzied and frantic giggles, driving her crazier and crazier the longer it goes on.
