I used to own the video Ticklish Interrogation. If you can get it for a good price, the tickling looks realistic when Misty Lang tickles Catherine Beaumont but not vice versa, so the video is at times worthwhile. Catherine does not seem to be faking her ticklishness but Misty's ticklishness is about as real as her bosoms, which ain't!
But at least Misty Lang is an enthusiastic tickler, and that makes the scenes where she tickles Catherine Beaumont even hotter. I especially like the teasing look on Misty's face when she tickles Catherine stocks-bound feet.
And for eye candy fans, Misty Lang is a looker. Too bad she's not ticklish.
