it's a special occasion for my carefriend (I called them my sub before but carefriend is the more accurate title) and I wanted to do something nice for them, and they asked for a combination of two things we've done before - thought-fuzzing (not quite IQ drain but making thoughts blurry and inaccessible) and catboy transformation. I suggested we try adding a sensation trigger for being petted, and they agreed.
We started with our usual premise, which is that I'm a magician and they're my familiar, through whom I channel magic. Our usual induction is me counting down and guiding them into sensing magic around them and inside them, but the last time they mentioned they didn't think they needed that, so we tried just telling them to sense magic: it worked but very faintly so we did the countdown again, albeit a shortened one.
Then I told them I'm summoning astral hands to transform them, and they might feel the hands, too. I did a countdown for growing their ears, with the astral hands rubbing their head until the ears grew. I installed a sensation trigger to make them feel petted whenever I said the word 'pet'. Then I counted down and had the hands rub their lower back to make their tail grow.
For the brain fuzzing, i had another pair of astral hands go into their head and knead their thoughts. I told them they didn't need to think, only be petted and purr, be warm and loved and comfortable like a cat in a sunbeam. Told them that the more I pet them the fuzzier their thoughts, and the fuzzier their thoughts the easier it is to be petted. I tried doing a bit of call and response to keep them under, and they started replying with emojis we put in our discord server for nonverbal play - which we haven't actually tried yet, just planned for, so it was so cool they used them.
We stayed like that for a lil bit. Then I took away the hands in their mind, unfuzzed it, took away the hands on their tail and ears and the petting trigger, and counted them up.
They still felt the ears and tails a little bit, but they wanted to keep them. I'll check on them their tomorrow morning and see if everything is good.
