I think my tickle (and foot) fetish originated when I was very young, at about 4/5. My aunt would come over every evening. She's moderately attractive, great feet though. She always wore nylons, mostly black, sometimes tanned. Anyway, me being a toddler, I used to get on and under everything, and as it happened, everytime that she came over, I'd be under the kitchen table just waiting for her to come in and sit down. She'd always kick off a shoe under the table, whether it was for me, or for comfort, I'll never know. Anyway, I'd constantly play with her feet while lurking under the table, she never seemed to mind it. I'd often tickle her, but being 4, I wasn't that "skilled", lol. As the months went by, I gradually found a way to tickle her. I think the foot fetish was caused because of her kicking off her heel(s) everytime I saw her, and the fact that my older female cousins often walked around barefoot,, but I do believe that the tickle fetish started soley (jajaja, epic pun. No? go away D with my aunt. Before ever tickling her, I often just scratched her soles, not hurting her, but light strokes. I guess that element just made it more exciting when I did manage to tickle her.
