Furry February Part 3/4 - Lab Hands (Patreon)

Every good doctor needs a good testing subject. Someone hardy and responsive who'll give them all the information they need - every twitch and squirm, every wriggle and writhe, it's all important for working out how the latest invention ticks - and how it tickles. Tickling is good for you! Laughter keeps you healthy, boosts your mood, and helps create bonds, so surely a robot designed to tickle will be much appreciated in every home across the country!

But what if it malfunctions? What if it's too rough, and scratches its users up? What if it doesn't know where to tickle, and isn't as effective as possible? This is what testing sessions are for! The robot's ability to locate and hone in on the most devilishly sensitive spots has to be perfected over time, and it'll take a few sessions to get it just right. The doctor knows that it learns from example, so she'll take one side, while the robot tickles the other.

The test subject is strapped down and almost immobile, wearing only a pair of leather boots to protect her feet ("They're way too ticklish! I wouldn't be able to stand it!"). Slowly, the machine whirs to life with a cheerful pip. From watching and listening to the doctor, it'll learn how to tickle and talk tickling like a champion - the brushes spin into action and begin tracing their fluffy wheels up the poor dear's exposed sides, eliciting an immediate squeak of sensitivity! She bucks to the left, right into the squeezing hand of the scientist, who laughs along with her as the cute little test subject shakes and shrieks with ticklish bliss!

The robot gets more bold. One brush begins to spin in the subject's taut armpit. This gets a nice reaction. Her arm quivers with the instinct to protect her sides, but to no avail - the whirring, fluffy brushes won't relent from their ticklish duties! All she can do is laugh as the doctor chuckles, low and sinister, massaging her sides with a devilish grin as the robot moves momentarily over her exposed, bouncing breasts, fluttering at the sides and torturously tickling her rosy pink nipples. Quickly, as the robot moves down to tickle her stomach, the test subject realises that she's getting a little excited...

As she realises how wet she's getting, the robot pipes up, declaring that its sensors have found an even more sensitive spot. Both the doctor and the subject react in surprise (though not horror) when a twirling brush begins to mercilessly tickle at the subject's labia, teasing the plump lips slowly at first before getting faster... the subject begins to moan between her laughs as the robot applies more pressure, searching higher, hunting for her aching clit, finding it, lighting up at her desperate moaning which turns back to giggles as her stomach and armpits are tickled-

It's something they need to tweak, sure. The doctor knows that her robot can't start tickling people to orgasms, not unless told to. Maybe it'd benefit from hands as well as brushes, so it can perform tasks and squeeze and grab and spider its fingers up a ticklish body?

She also knows that people will want it to tickle feet. She can't alienate a whole branch of her market - the robot has to know how to tickle and worship soles! Either she can find another test subject, or convince this one to pull those cute boots off, because excruciatingly ticklish or not, the robot has to learn, and it may take a while to make sure everything's perfect...
