my first memory of tickling nylon feet was my grandma when she came to baby sit me i think I was 5 or 6 she came in took her boots off and put her slippers on thats when i noticed she was wearing tan tights reinforced toe i was playing with my lego on the floor she came a sat on the sofa behind me mum and dad then said be good and kissed my head and went so I kept hearing something drop so I looked back and she was dangling her sslippers they both were on the floor near her nylon feet i found it hard not to stare at them after a while my back began to hurt so I then sat against the sofa i was next to her feet i got curious eventually and dragged my shaking finger down her arch she then jumped and said omg that tickled i asked if her was ticklish she said yes very so I just playfully tickled her a few more times then i though Id better stop as don't want to get in trouble then we relaxed and she put me to bed i don't know if she told my mum and dad i have a few more stories about tickling her/playing with her feet if you wanna hear then
