In a sticky spot [m]

This is nothing yo do with my sexual escapades. Its about a boy and a girl who are supposed to get married on 02/14.
The boy say B, dad was a great friend of mine. He was 10 years older to me but we somewhat were close friends. But on 09/2018 he died of a accident. I was very sad then but live moves on. Few days back I came to know B is getting married to a beautiful gal G. B and G had met in college and had fallen in love.
But the irony is G’s mother had at one time (when G was not born) had a secret affair with my friend (B’s Dad).
And she had become pregnant and had delivered a baby gal B.
I was told about this by my friend long back in early 2000’s. Now I am not sure how can i say B n G that they are brother and sisters.
By the way G’s mother had died long back in 2010 types

Old love [f] new city

I had met this gal when i had moved newly to the city. Lets call her S. We had talked over the phone before i had landed in the new city, she was also new to the city. She was doing her masters.
As soon as we met we clicked and one thing led to another and we were having sex. She used to come to my place on her off days and we used to have a blast.
But as all good things come to an end our relationship also ended but not before we had the last fuck.
She got married and move to Germany and 2 year later i also got married.
We used to communicate via email but very rarely.
5 years passed, Due to work i had moved to London and out of the blue i get her email, it said she misses me and is not happy with her marriage and they have a baby also. I mail back like a friend saying things will workout not to worry. We email back n forth and i give her my number and she calls me we start talking and remembering the old times
Slowly from talking we moved to sexting, i was feeling guilty for my behavior but was not able to control.
And then a opportunity came i got relocated to Germany but still some 4 hrs distance.
She was very happy she kept on asking me to come over. After some time my wife went to meet some her relative in london and i went to meet her.
She came to my hotel and as soon as i saw her i was rock hard, we hugged and she was able to feel the hardness but behaved aloof as her son was along with her. We planned to meet the next day alone. Her husband was away for work.
The next day she came alone, she had dropped her son in the play school. As soon as she entered the room there was this tension in the room, we were all alone.
She went and sat in the sofa I was sitting across her, we started chatting. She came over to where i was sitting to show me the pic of her cycle that she had recently bought. I could see the shape of her tits they were small but firm, I could smell her hairs it was intoxicating, she leaned a bit I looked up and our lips met it felt so natural.
In no moment we were in the bed undressing ourself, no foreplay nothing i was into her wet dripping pussy.
My cock was hard like a rod, i was deep into her, she was almost screaming.
We moved from missionary to doggy style i knew it was her favorite position. Fucked her for almost 30 mins as i was about to cum i took out my dick and poured everything over her tits.
We lied naked for almost an hour, i was playing with her nipples and kissing her.
We again fucked and then she had to leave to pick her son from play school. But before leaving she made me promise her that i would come back again for more fun.
