I've been a hobbyist for a little while.  And I've told the providers that I've seen about my little, quirky fetish. (please refer to my screen name. lol)  
The only problem is that most of the providers I've seen aren't really into foot play.  And the ones that I've actually "connected with" over this are...retired (For lack of a better word)

Apparently wearing socks during the deed leads to better orgasms...

I was looking for a provider to wear socks...now, this?!?!?

None of you ladies like your feet played with??

You asked a question at 10:30 PM on a Saturday night and now you are wondering why no ladies responded to you by 8 AM on a Sunday morning???

Responded???

I love footplay! Socks is a little unusual(typically sheer thigh highs or nude), but might be even more fun because my feet are very sensitive. Size 91/2 with high arches

Any lady who has experienced getting their toes licked while in missionary knows EXACTLY what I'm talking about. Especially when the tongue goes between the big toe and the second one! OMG, it's amazing. Given the feeling I've experienced, I take it upon myself to actually do some inbetween the toe licking and arch licking myself. Someone I've seen recently can vouch for that .
