Gosh that is a difficult question for me,because I've never "acted out" my tickling fantasy yet.I picked stranger, because I've seen some ladies around town that look very inviting.Also, my tickling fetish got cemented when I was 8 and saw this 18-19 year old high school getting tickled by 3 guys, just non-stop tickling rampages.It has stayed in my mind all these years.I was turned on at that age and didn't realise it.
