The one you want to look for is Beth. She likes to be tickled, puts up almost no resistance, and is a helpless giggler.
If you can find old Tickle Abuse videos, look for a cute brown-haired girl named Lily. She was a nerdy type with glasses, and she had a light, soft-squealing, cascading giggle. She only made two videos for them and a few for other companies before quitting five years ago to get married, then divorced after two years. Now she works at home for a call center that in-sources customer service for U.S. companies. She lives about a mile from me and has "adopted" me as a friend-father figure. She's very sweet, if a bit weird (otherwise, why would she kitten up to a man over twice her age?). She texts me several times a day and phones most nights. Every Friday night, she comes over to binge-watch Netflix. At some point in time, we usually interrupt Netflix for a 4 or 5 minute tickle session, sometimes two. Unlike the videos she made, she keeps her clothes on, and the tickling is very G-rated.
