I came across a log from a German laboratory, accompanied by a picture. There may be some grammar weirdness and spelling mistakes, so bear with me.
Cygnus Systems file report on subject 46-3478
"We went through 5 months of extensive testing to evaluate the most ticklish spot on 19 years old Jessica's feet, which was not an easy task
at all, because the subject turned out to be extremely sensitive already - our tests would rate her a 0.9 on a scale from 0 to 1. However, we were desperate to find that 0,99 spot."
"Each day would start with the subject undergoing a thorough, 3 hours long
pedicure. Because of the subject's extreme sensitivity, we had to securely
strap her down, placing her bare feet in a special contraption which holds
the feet perfectly still, while securing the toes in a bent back and spread apart position
using small clamps. That way, we had full access to not only
her soles, but also to the sensitive area under and between her toes. Without
the clamps, the subject would most certainly have tried to cover those areas by
clenching her toes, which would have slowed down the cleaning process.
Using stiff electric brushes, pumice stone and high pressure
water jets, we made sure to remove any kind of dirt or even dead skin which would
negatively affect the testing session."
"On Jessica, we had to try various techniques.
Neurophysiologic measurement of the brain's electrical activity in response to the subject
being stimulated on her feet led to the best and most accurate
results. The drawback was that we had to painfully scan each
and every part of her soles - usually, it would take us as long as
12 hours to scan and stimulate only 0.01 square inches of skin.
During that process, the girl seemed to suffer a lot and repeatedly begged
us to "stop tickling her", sometimes even after only 5
minutes of sole stimulation. Of course, we did not pay any attention
to her pleas - what we did though was gagging her, because her screams
and constant laughter were rather distracting."
"On day 152, we finally achieved to find Jessicas sweet spot - pretty much
in the middle of her left sole, right under the ball of the big toe, the diameter
being only a fraction of a hair's width.
It turned out to be even a 0.999999972, by far the highest number ever measured, and we all were very, very pleased."
"Now we were ready for phase 2:
Jessica was stripped completely naked.
After the catheters and tubes have been insert and taped into position and the oxygen
mask has been placed over her mouth, we attached a clit tickler and a vibrator, adjusting the
straps around her thighs and waist until they fit perfectly.
Now, Jessica has then been blindfolded, and put into a tight straitjacket.
We placed her inside a custom molded case, where she was strapped down,
lying on her belly. Her calves and feet were outside
that small box, sticking through holes.
A camera inside the box pointed at Jessica's face, EEG and ECG were constantly measured.
Hooked up like that, the subject can easily survive 2 - 3 years inside that box,
at least if you carefully monitor the vital signs every month and act accordingly.
We then closed the lid, and the whole box containing our completely
immobile Jessica was slid into an opening in the wall of our storage room
(which kind of looks like a morgue), and locked in place.
Only her bare feet and calves were now sticking outside the wall, soles facing
up, the rest of her was completely hidden."
"Her legs and feet were now placed into custom molded,
skin tight "cases" made of stainless steel (think of them like "steel stockings"),
which were securely attached to the ground and the wall, rendering her completely helpless.
She was now unable to move her feet even the slightest bit - not
even wiggling her little toe was possible.
Both of her feet and legs were fully covered, except for a small diamand-shaped opening
cut into the left steel case, right at the sole of her foot, exposing the delicate
soft and highly sensitive bare skin underneath - Jessica's freshly discovered
sweet spot.
"Now we firmly attached our custom built nano stimulating device on Jessica's left
foot, pointing down at her sole, carefully positioning it to exactly focus on the
girl's sweet spot. (as seen on the picture)
That wonderful device is able to stimulate the delicate nerve endings of Jessica's sweet
spot at the highest possible level without actually penetrating and hurting the skin.
If you compare the tickle sensation from scratching a ticklish girl's bare
sole with a fingernail to the one derived from stimulating the same spot using our
nano stimulator, the relationsship would be approximately 1 : 1000."
"Back at our control desk, we switched on the clit tickler and the vibrator. They were programmed
to operate at high intensity, carefully keeping her on the edge of orgasm, but never
allowing her to actually come - as we found out, being in such a state enhanced Jessica's
overall sensitivity to tickling."
"Now, it was finally time to turn on the nano stimulator. As we pressed the button, the device
immediately started to operate at a high level, giving Jessica a tickle sensation she has
never even remotely experienced in her life. She thought the tickling during the testing process was bad -
but this one was a lot worse.
Looking at our monitors, we could she that she was laughing hard and you could tell she was trying to trash about, pulling her foot away and
escape from the insane tickling - but luckily, the restraints held her firmly in place. Her feet didn't
move. We could see a little trembling on the skin of her foot at the position where it is being stimulated, and there was a tiny drop of sweat, but that was all -
there was nowhere to go, she just had to take it.
It was fascinating to watch her EEG going crazy. We could hear her muffled screams
through the wall, but they didn't bother us now - we were all very happy that we
succeeded in our experiment."
"We switched off the lights in the storage room and locked the door, leaving Jessica to
her ticklish fate. Every hour, the stimulator would stop for 5 minutes, letting her
catch her breath, only to continue at an even higher pace. By the end of the day,
it would have reached it's maximum level.
A pity there will be nobody in the lab to witness it - after 5 months of hard work, we're all in desparate need for a vacation.
Let's see how she's doing when we come back."
There ends the log. The date of the last entry is 09/20/06.
One week later, we would read in the newspaper of a group of German scientists that was tragically killed in a plane crash on the way to Laos.
