I wouldn't say that I have a foot fetish, per se. However, toe sucking - or shrimping as it is referred to in those circles - has a rather hypnotic effect on me. Not getting my toes sucked, so much as sucking on someone else's toes. Especially in a hot tub.
Call me crazy, but I could do this for a long time without needing a break, although a nice cold beer or glass of wine sure doesn't hurt matters any
Peace,
Pierre
