I've been experimenting with Ideogram, the only AI generator I know of that mostly renders what you describe.
But as others have noted, it is REALLY hard to get it to show actual contact between tickler and ticklee. And clearly that's gotten worse. A few months ago, people were giving Ideogram prompts that said "x person tickles y person's feet" and it would at least sometimes show fingers touching feet. Now if you put that in, you'll get two people smiling at each other with no contact. Clearly the generator has been programmed to avoid any contact that could be considered sexual, including with feet. Sometimes you get lucky and it'll give you glancing contact, but it's hard to get there, if you ever do.
I tried a bunch of times to get it to show my old Pink Dragon character, from my long-ago stories, tickling Disney's Cinderella and other characters. I
almost got there. I'm almost happy with the image (despite the dragon being more cutesy than I wanted), but it's a struggle to even get it that close to actual contact. It does better if you aim for anticipation, like the second pic. ("Magic" tickling, like in my current profile pic, is the easiest thing to get... that works much of the time, for now.)
P.S.: AI in a nutshell. One where I got actual, almost unobtainable contact with feet... and the girl has 4 legs. Because of course she does.
