I didn't have long to ponder before some clanking in the hallway alerted me to someone approaching my room. The door swung open and in squeezed a large metal cart as wide as the doorway, filled to the brim with devices and machines that were practically spilling onto the floor. A small bump was heard as the cart collided with my workbench, and from behind the metal clutter my friend Katherine poked her head around and smiled brightly. Her long brown hair was tied back into a single ponytail that fell to the waistband of her jeans, and her tank top was both flattering and practical - she hates sleeves when she's working with machines.
In her chirpy voice she called to me "Good morning sleepyhead! Sorry for forcing myself on you like this, but I just couldn't wait to try these out on you." She began maneuvering her cart around the workbench, continuing to talk as she wheeled it closer to my bed. "Your entire family is out for the day and you were fast asleep - and I mean fast asleep - so I couldn't resist tying you up like this and getting my things. I took the liberty of stripping youth save time." Reaching the foot of the bed, she left her cart there and walked up to the mattress before sitting by my naked torso. Being nude didn't bother me at all - besides, she'd seen me naked several times before.
Katherine was a rare genius when it comes to machinery. Both of her parents are robotics engineers, and their talents have clearly rubbed off on their daughter. Already she could turn a pile of circuitry and spare parts into something neat and useful; a while ago she essentially built a small wheeled robot from the ground up, which now helps her carry loads around her 'lab'. Actually, she spends a lot of her talent on her tickling passion - which is rival to my own - creating clever contraptions and machines that tickle me out of my mind. However, when she first started she had no one to test her inventions on - and she wanted to fine-tune devices to specific subjects, so she couldn't use them on herself - so when she heard of my love for tickling she asked if I was okay with being her guinea pig. I answered as soon as she asked. Pretty soon I was spending every other weekend in her basement - her 'lab' she called it - strapped to an examination bed while Katherine invented and tried out new ways to tickle torture me to my limits.
As the brunette sat beside me, I chuckled softly. "I should've guessed it was you," I said. "I might've protested to you stripping me naked, but you've seen everything I could hide with clothes."
"Damn right I have," she stated assertively before quickly scrabbling her nails on my bare belly, sending me into a sudden fit of laughter. She may like inventing machines to do the tickling, but she still likes tickling me herself. "As ticklish as ever I see," she observed. After a few more seconds she let me catch my breath and continue.
"Since I am all prepared for your experiments - and I'm in no position to decline - I'm ready to be tested on. What did you bring with you?"
Her grin grew as she heard my response - she always liked it when I was a willing subject. Walking back to her cart, Katherine surveyed the devices and machines she brought over from her place. "I've brought a lot, and I've got three ideas to start with," she said after a while.
"I brought over something new today. I've got fourteen little machines, each with a suction cup that will stick tightly to your body once activated. On the inside are lots of tiny feathers that can move at various speeds, tickling the skin that the gadget is attached to. They are controlled by a remote that I will be using to adjust the speed of each one as well as which ones are on or off.
"My second suggestion is something a bit bigger. I've got three 'feather discs' as I like to call them. They have a strong arm that attaches to the bedframe and supports the disc, allowing it to spin unhindered across whatever part of the body I position it over. They too are controlled by a remote that sets the speed of the discs. The long plumes are very soft and light, but at high speeds they can be just as torturous.
"Finally, my greatest prototype yet. This little beauty was the hardest to put together, but will be by far the most advanced tool I've ever used on you. A pod twice as big as your head will be suspended above your body by four supporters that I will attach to your bed posts. From this pod will emerge a few small robotic arms, equipped with various tickle tools, that I will direct to tickle the sweet spots on your body - which I know very well.
"Well, which one do you want to start with?"
