Trying not to blush too hard, I chose the feather chair as feathers, while tickly, weren't quite as bad as the prospect of several dozen robot arms or brushes tickling me all over. Although I had a love of tickling, it was still morning and I preferred a softer start when it came to Katherine's creations. Sitting down on the recliner, Katherine soon got to strapping me into place "I'll look forward to see you sitting in here at some point." I said, my blush remaining as Katherine's chest got very close to my face as she strapped in my arms above my head, trapping me completely.
Not appearing amused at that at first, Katherine gave me a clinical look. "Not while you're still the test subject," she answered.
"I remember the last time you were the test subject. Certainly seemed to enjoy yourself Kitty," I teased back, getting some satisfaction as I saw her face gain a slight red tint from the memories she had when I tickled her last. Her nickname wasn't just from her own name but how I could get her to make cute mewing noises with a few soft touches of a feather to her nipples.
Suddenly breaking out into a smile, Katherine reached into her pocket and pulled out a small, fluffy feather. "Time to begin the preliminary examination," she announced before bringing the feather down to my thighs and brushing it up and down the bare skin, getting close to my groin.
"Heheheennoohoofahhaaiirreheee!!" I tittered as the the tickling sent electric shocks through me. I knew exactly what she was doing: tickling me to make me aroused and, thus, more ticklish. It was a trick she had discovered during the first experiment and had exploited it mercilessly ever since. I couldn't complain really as I loved the caress of the feather on my skin and would have gotten in a similar state the instant that the feathers on the chair had started tickling me, but starting early like this seemed kinda unfair.
"Subject seems to be experiencing some discomfort. Alternative methods shall be used to remedy this., Katherine whispered in my ear before I felt the feather suddenly tickle my erection, brushing the underside with long, slow strokes. The sensations that effected me before turned from electric to fire as the tickling of my cock made me scream with laughter and built up the pleasure I was feeling considerably.
"NOHOOHII'MMFIIANNEHEEHEE!!" I cried out in protest to Katherine's teasing scientific words, unable to resist at all as that soft, small feather tickled my cock from base to tip, always keeping up a slow pace that allowed the plume to linger in an excruciatingly ticklish way. I tried to bounce in my chair to escape but without much luck, the straps holding me down doing their job well. I continued to laugh and squeal, realising that if only one feather could do this to me, the dozens lining the chair would be even worse.
This was going to be fun.
Eventually, the feather was pulled away and I was left a giggly horny mess. Katherine looked down at me and I could see she was smiling broadly. Tickling me into states like this one always made her chipper "Subject appears to be experiencing enjoyment of the experiment. Time to start the process completely." She looked down to the feather in her hand before giving another smile before continuing in the scientific talk she loved to use during our games "Or perhaps the experiment can become a little more... intimate," she said, her eyes shining as the feather twirled in her fingers.
I gave a shiver of pleasure at her words and waited for Katherine to make up her mind. She eventually...
