Okay, sure. I'll take a shot.
I met up with a good tickle friend for our fourth playdate last week. We met on fetlife, and she enjoys being tickled as a sensual / sensory experience, even though it isn't explicitly a turn on. I started off, as I usually do, by giving her a massage. This time, I applied a hot pad beforehand to allow additional relaxation and loosening of muscles.
In previous sessions, I've always restrained her with cuffs and / or rope. This time I had asked to just pin her and restrain her physically, because it would be something different and allow for more physical intemacy. While she is very ticklish, she has a remarkable ability to stay pretty still and endure it (giggling her head off all the while, of course) - so I wasn't worried about getting an elbow in the teeth or anything.
So after a relaxing massage and some head scratchies, I started off with some lightly teasing touches. I basically just trace a finger or fingers over a sensitive area, indispersed with movement traditionally over less sensitive ones. Due to her extremely sensitive nature, this alone is enough to start her giggling lightly and occasionally twitching.
That goes on for a while, and I slowly increase the intensity by continuing to apply these light touches to more sensitive areas, such as her tummy and sides. So as not to overstimulate her, I will sometimes return to gentle back rubs, head scratches, cheek caressing.
As I want to increase the intensity further, I start to indisperse very light nail scratches on tender areas such as her inner thighs and sides. These get her laughing pretty quickly. At one point I lie beside her, my shoulder on her left arm, hold her right arm with my left, and pin her hips under my left leg. In this way, I have one free hand to tickle what I have found to be her worst spot, her arm pits, which I can only do for a few moments before she needs a break to catch her breath.
I don't want to leave her feet out of the fun, so at one point I move down to them and use light scratches on her slightly tougher soles (pedicures are a rare treat as she is a poor student). Despite their tougher skin, the tickling still illicits squeals and laughter from her.
I still haven't really pushed her that hard, because I know she doesn't love it the same way we do. It's still super fun due to just how fantastically sensitive she is
In our prior session she had expressed a desire to switch and get to tickle me as well. I ask her about this and she agrees. She starts off straddling my waist and attacking my stomach and chest with gentle flutters of her long nails. It's enough to get me twitching around and occasionally laughing a bit, but I'm nowhere near as sensitive as she is (at least, not there). She still laughs and exclaims how much fun it is to get to tickle me back, and I encourage her to explore and go for the gusto.
After tickling my upper body to moderate effect, she moves down to my feet. Since we aren't using bondage today, I lie face down and she sits on my ankles, as this will greatly limit the chance of me kicking her (I had warned her that I'm a kicker - my feet are much more ticklish than my upper body and I can't help it). She currently has false nails on, which are pretty long (due a manicure, she said, but like the pedicures, can't afford it right now). I had also just had a really nice pedicure myself the weekend prior, so my feet are definitely sensitive. Combined with her long nails, I was in for quite an experience! I've been tickled while tied up before by my wife, but this specific position made my feet completely immobile while she poked and scratched at them with her long nails. It was... intense. I was howling with laughter, stuggling and bucking but my legs remained held fast in place. She probably only tickled me like this for a couple of minutes, with occasional momentary breaks to make sure I was okay, but even so I was sweating and panting afterwards.
We cuddled for a long time after. A wonderful experience I'm hoping to repeat again soon.
