Excitedly I slipped on shorts and a t-shirt, knowing that they'd come off once I got over there anyway. I've always looked forward to Katherine's experiments, and since I was her only test subject they happened at least once a week. Occasionally I even got the privilege of trying some of her machines on her, but she much prefers to be the one at the controller and I'm better strapped to the table than behind the controls. Still, it goes to show that she has a sense of fairness despite her cold analytical demeanor.
A quick jog and I was over at her place ringing the bell. Both Katherine's parents are robotics engineers, and it is often suspected that they are the source of her mechanical aptitude. Her parents are actually the source of many of the robotic parts Katherine acquires, them being spare parts from her mother's or father's research. They maintain a steady supply of whatever she needs, and she accepts all parts given to her happily.
Footsteps pounded on the wooden floor inside. Katherine burst out of the door, grabbed me, and pulled me inside before I could even respond. Apparently she had been awaiting my arrival anxiously, as she wasted no time dragging me into the enormous basement. The room was filled to the brim with all types of machines both large and small, from ingenious robots to modified house items to even mechanical furniture specifically suited for the purpose of tickling. It always amazed me how much this girl could do in so short a time. The room looked like a mess, but it was a given Katherine knew where everything was.
"Looks inviting," I joked, looking at some of the things she made. One particular invention looked particularly complex. Red cushions lined a metal recliner, except instead of ending in a single footstool it split up so that both my legs would have their own resting places. Multiple drills were stationed up and down the length of the chair and legs, each one with many white fluffy feathers attached to the drill bits. I suspected that they were intended to tickle me to hell and back.
"Doesn't it? Spent days on that one, quite proud of how it turned out." Katherine stood there in her white tank top and booty shorts, her brown hair tied back into a ponytail that fell to her waist. She dislikes sleeves and pants legs because they get in the way of her work, though I suspect she also dresses like that to show off her butt. "Before we go any further; strip. Naked. Now."
Quickly obeying, I lost all shreds of material that I wore. Some might feel uncomfortable in such a position, and I felt a blush growing in my cheeks, but I was on the whole okay with being nude - so long as it was in private and among friends. "Done, now what did you have in mind?"
Katherine smiled and gestured to the machine I just looked at."That's something I'd like to try out today. As you've probably guessed already, the feathers are going spin across your entire body at speeds I control. It's simple, but I'm sure you'll have a lot of fun with it."
"Or if you prefer lying down," she continued, pointing at a bed with a large machine suspended over it. "I could chain you to this one. That machine is host to tons of robotic arms, and I've been writing the automatic script for a while. Don't worry, I've got manual control too."
"Finally, there's this baby." This time the object in question was an examination rack, currently lowered. Above it was a hulking machine, from which protruded several arms each ending in a wheel of soft bristles. "I've spent months on just the blueprints for this thing. It's unconventional, but I'm sure you'll like it."
