A frivolous woman

I don't know how to write stories, it's easier for me to write them in languages I don't speak, like English, because errors are invisible for me!
I posted this one as a couple of comments in Kate's blog (http://xhamster.com/user/KateandJessica/posts/391417.html) and, as two people liked it, I'm now posting it here

Other than my own, only two married ladies I had in my bed. One of them was exactly my age and I had her for the first time when she was another man's girlfriend. This romance lasted from our 24 years old until our 44, with interruptions, through marriages and divorces of we both.

It all began in a bar, at night. We were sitting in a bar on twin armchairs drinking gin and I "casually" passed my arm on her armchair. She put her neck on my arm and began to do circular movements with it, pressing my arm. I thought that my arm was bothering her and took it off. Then accompanied her to her home and went to mine, to sleep.

Next day it was Saturday and she phoned me with an invitation to see a school which was being built into a park. I was no architect nor teacher in those years, neither she, but of course I accepted the invitation.

We sat by a tree in the twilight, were talking and she whispered "let's speak this way...". I turned my face to her and assented. After a smiling silence I put a kiss on her cheek and she, in an intense and sweet way, kissed my mouth...

One minute later her body was moving under mine and my shirt was being freed of the pressure of my belt. "Hold on!", I said. At those times my country was governed by a moralistic Military Dictatorship and nothing good would happen if police appeared.

"Let's go to an hotel" I proposed.
"But you don't have the money for that", she replied.
"Yes, I have. And anyway you have a little too."

We walked nearly thirty blocks to a cheap hotel I knew of, not very fast because we kissed by every tree and street lamp. This was the beginning of the more lasting relation of my whole life.

When we were finally in our room she asked me "Turn the lights off, please, I'm shy"
Her shyness seemed to disappear a minute later when she was over me doing what I knew could be done but had never lived...

As a closure, I will tell what happened two days later.

While walking by the street I asked "And what will you do with H?" (her boyfriend)
"Please don't talk of personal affairs", she replied.
"But why have you been with me?", I asked.
Forty-three years later her response still sounds in my ears:
"Because I am a frivolous woman!"
