Ok
Have her tied standing straight up, arms over her head, legs spread. Start her in a black bra and black panties.
hen have a vicious Female Lee stand behind her and tickle her from her knees to her armpits for 30 minutes.
Then same position, with her ass to the camera and tickle her front, Same way as above for 30 minutes. Not sure if you can shoot this split screen but that'd be cool
If you wanna throw a few forced Orgasms in there 'd go for it.
Eventually her bra has to come off!
BTW given some of how vicious your past work has been I was hoping you'd answer. All I ask is your cruelest tickler(s) do it. No pansy stuff!
