So...a good old standby (literally): watching a young woman go barefoot (preferably no shoes in sight), with moderately dirty to pavement-blackened soles (she's been barefoot a WHOLE LOT and obviously fucking adores it), then (later, wherever) rubbing one out. mmmmmmmmmmm
Incredibly sexy watching beautiful girls walking barefoot, living in the country it happens a lot because you can walk in the grass, and especially at barbeques with all the girls sitting on the grass with lovely painted nails with their shoes off, I find looking at beautiful curved ankles very erotic
Agreed that bare feet in the grass tends to make my shorts tight, but I gotta express a preference for unpolished nails. Just my $0.02...
I've always had a foot fetish from a young age, a girl with small well looked after feet is such a massive turn on, if her feet are cute and sexy then every part of her definitely will be.
