My first sexy feet experience

I was on the train on my way to work and a pretty girl in her late 20's was sitting opposite me. I had the urge to see what kind of shoes she had on hoping that i could see her toes and if she had painted her toenails. I looked to see what she was wearing, and before I actually tried to check them out, imagined in my head what colour her toenails would be. My heart started racing but i didn't want her to notice that i was looking so thought I could pretend I was on my phone and video them rather than making it too obvious. I pointed my cam down and pressed the record button which then made a loud noise and was blatantly obvious what I was doing! Shit I was caught out! Not 100% sure if she realised, I just put my phone into my suit jacket and tried to act normal. After about 20 mins and still not seeing if she even had her feet on display she put one leg over the other and brushed her foot on my kneecap and her foot was on display right in front of me! She looked at me and said "sorry, me and my big feet" I now had the perfect excuse to look at them after what felt like forever. OMG! it was so worth the wait! She had black flip flops on but had the brightest pink neon toenails with like a fine french white pedi tip. Whilst looking at her toes I just had to start a cheeky conversation about her feet and said "You hardly have big feet do you?.. they don't look bigger than a size 5?" She smiled and said "Good guess... they are a 5" I told her that her nail colour was really nice and asked if she painted them herself. By this time I could feel my dick growing in my suit trousers and looked down to see how visible the outline was. I then asked her what line of work she was in and she told me she worked in a nail bar in Bishops gate and one of the girls gave her a pedicure last week and has to have one every other week so they look perfect for her clients. I told her, well she done a great job and sat back in my seat and opened my legs hoping she could see the size of my penis down the side of my leg. I didn't think she noticed until the train stopped at Liverpool St when she just smiled and said "How are you going to walk with stiffy? and good luck with your video!" What a little tease.
