One story that stands out occurred at one of the West Coast Gatherings. The lee was tied down spread-eagle and a certain dvus ler was giving her the business like you never saw Eddie Haskell give Lumpy. Well, he's kneeling between her legs and he's hunched over kinda like that piano-playing kid on the Peanuts... (his name escapes me at the moment).
So, eventually, he hones in on the tummy. The lee was wearing pants with an elastic waist if I remember correctly, and she was wearing them in a fashion the almost divided the tummy evenly between above the beltline and below the beltline. And said beltline created a delicious slope. Our ler started on the slope above the belt line using a curved, splayed finger technique that was so fast yet SOOOOO soft it would have made Bud Powell proud. Eventually he settled on the slope below the beltline, fingers still going at a blazing speed, yet oh so tender. It should be noted, the lee was extremely responsive to begin with, but when he began with her belly, she reached new pitch... then when he settled on that slope, and began to move his hands out then in, then out then in the up, then down, then out then end.... I was sure we'd have to notify her next of kin. I
It was really an amazing scene to behold, because even though she was screaming with at an ear drum shattering level, the laughter that just kept coming and coming was the kind of delicious laughter that sounds like someone is in their very happy place. I'd say this tummy tickling lasted at least 45 seconds.
Eventually, the ler moved on to other spots and after some time the session was over. After she had had some time to recover and compose, she was talking about it and said "...can I just say, I thought I would DIE when you were tickling my tummy!!!.." ... and that made two of us! :- )
