Every attractive female I ever laid eyes on. Especially if they were wearing flip flops, they have to be tickled on the spot, until they were in hysterics! Grab their ankles in an armlock and rake their soles. I would have to do it sparingly, because if I overdid it the cops would start trying to think of ways to catch me, like heat sensor cameras or something. But if I only did it here and there, the individual girls I did it to would just be dismissed as crazy or making shit up. Of course I would also sneak into some armored trucks, bank vaults, stuff like that and amass a fortune. Then, if my victims started to find out they were not alone and start comparing experiences and putting 2 and 2 together, by then I'd have hot women hanging all over me for my money and would have no shortage of women to tickle!
