One of my favorite things to do with a girlfriend (or even ladyfriend, for that matter) is accompany them to the nail salon for pedicures; they enjoy the company and I enjoy the show, and in any event all the girls I've went with knew about my foot fetish and had no problem showing off for me.
It is a remarkably sexy place for folks like us, which I always found peculiar and funny. But oh boy: Sitting in a comfortable chair, watching a nice pair of feet wet and glistening in the air propped up high on a tower of pillows getting mercilessly scrubbed with a stone, eliciting giggles, squirms and other various sexiness is just too much.
One of my earliest girlfriends (I was 16 or so) actually noticed I had a foot fetish while she was getting a pedicure; she couldn't miss the captivated attention I was paying her feet. From across the room (upon retrieving the nail polish she wanted from the wall) she stared me dead in the eyes and mouthed clearly, "I'll let you play with them later", and winked.
Hahahaha, I practically passed out. Good stuff.
