Accidentally Flashed Neighbour

We live in a ground floor apartment which is close to the street. I was home alone and had just showered one spring evening and walked into the bedroom naked, completely forgetting my wife had taken down the blinds for cleaning. I switched on the light, and revealed my nudity to my passing female neighbour who gave a very definite reaction - and I noticed her look right at my cock.

I quickly dressed and called at her door to apologise, explaining my forgetfulness about the lack of blinds. She was very relaxed about it and even, although it may have been my imagination, seemed a little flirtacious with me (and more smiley than usual).

Since that day, every time I've seen her in the street, she has looked me up and down and when I see her do that, I start to get hard. During one particular neighbour social event, she sidled up to me and asked if I'd be getting naked during the evening. I didn't know what to say and put it down to the wine she'd been drinking. I asked if she'd like me to be naked and she just smiled.

I've masturbated countless times over her seeing my cock and hoping she is doing the same. She's an attractive 40something woman (also married) and I find it such a turn on that she's seen my cock.

Would I fuck her? Definitely. Would I like her to suck my cock? No question. Do I think either of these things will happen? No, unlikely. Still I am able to enjoy the fantasy of her having seen my cock.
