Nice pics! Those are definitely doable. Has she worn any other types of shoes or boots? I would make it a rule that she has to leave her shoes at the front door (down stairs). Make sure to get pics if you get any action. Also if you can get any candid pics of her feet that would be great too.
I'll post my "action" pics, I have it for every pair she was wearing. I have lessons once a week and through last 4 months I've had about 5 actions - it's not easy because I/m not living alone… I haven't pics of her feet, she always has a pair of ballerinas which she wears after putting off her shoes.
There is a way to get your hands on those boots, and for a few days, wait inside the front door with a bucket of water, as you see her approach it, open the door and throw the water outside, as though you're cleaning the path, soaking her boots in the process. Then appologize profusely and tell her to leave the boots with you until next week, during which time you'll have them dried out, cleaned and polished.
They'll dry out overnight and that still gives you several days to have fun with them, before handing them back.
Sorry for delay but had technical problems. Here are pics from last year - I was so horny that after few seconds huge amount of cum droped on Karen's shoes. I cleaned them but not from inside - there was a little cum, she didn't feel it while putting her feet into the shoe. http://imageshack.com/a/img921/8926/iKAK6g.jpg http://imageshack.com/a/img922/2213/5W1eDZ.jpg
