I learnt a long time ago not to judge if a woman was sexy, just by her looks. Some women who look hot show their cleavage in order to get admiring looks from men, never intending to go any further. Others who don't really know how to make the most of themselves turn out to be really great in bed.
I'd been married for twenty years before I fucked someone other than my wife. I was only getting sex once or twice a month and only when she said we could do it. Given the infrequency of its use, I probably was so surprised when my cock went into her pussy that the fuck didn't last very long. My wife would have been bored with the same fucking and anyway had plenty of other interests besides sex. I was away from home working and staying at a hotel over a weekend when it was offered. I thought "why not?" I can still remember the moment when I pumped my load into the woman -- we were doing it bare-back.
That was a one night stand. Several others had followed, always when I was away for a couple of weeks working . Then I discovered internet dating. I was too old for Tinder. Let's face it, any good looks I had in my youth were now gone, although I wouldn't call myself ugly. I exchanged messages with some women my age and eventually one invited me to her place even though she knew I was married. She sent me her photo. Not to be rude, she wasn't good looking. I very nearly didn't accept but thought that the photo was like a passport-photo and that it cast her in an unflattering light. She lived in the next town. I was able to organise a few hours off from work and I drove over to see her. After all, I could always make some excuse and leave.
The photo didn't lie.
We sat and had a cup of instant coffee that tasted terrible. We ran out of conversation before I'd finished drinking it. Nervous and shy, she had a laugh like a corn-crake. I wondered how I could make an excuse and leave, but as it had taken over an hour's driving to get there, instead suggested that we went to bed. She agreed immediately and obviously had been expecting me to turn her down.
Her bedroom was very neat and tidy in contrast to the rest of the house. She told me to close the curtains and while I was doing that, quickly undressed down to her bra and panties then hurriedly got into the bed and pulled the sheets up to her shoulders so all I could see were her bra-straps.
