Like a few others have said I myself find upskirts a massive turn on , I find it particularly arousing to get a view of a woman's knickers on show weather on purpose or by mistake its hot and even more so for me if they tight little white cotton ones!! I also get equally as horny when I know my wife has or is getting upskirted as I love the thought who ever it is is getting a good view of her gusset and have loved each time I have been lucky enough to witness it happening
....I pretty much love most things involving knickers tbh, I'm not a wearer of them or anything but can never resist a look through a knicker draw or worn ones in a wash basket should the chance arise to have a look and a sniff , that said would happily allow others to enjoy my wife's as well in the same way which would be just as much of a buzz !!
