No question about it....sniff them and wank!
To have a pair of stockings or (more likely) a pair of tights, which a woman has worn at work all day with a pair of sexy high heels or boots is real treat. I love to sniff the feet while I wank....love the smell of them.
I'm very lucky I live in a large apartment building with shared bins in the basement...I often have a rifle through the rubbish bags and come up with discarded laddered tights. To sniff the feet, not knowing which woman in the building has worn them is a huge turn on, and I never fail to cum very very hard. And I can tell you some of those women have very smelly feet!!!
