Hi dear people of r/gonewildstories,
since this story will have a longer introduction, I will mark the part when the action begins with some —.
Some time ago I posted two stories of me fucking with my girlfriend´s sister ([Part I](https://www.reddit.com/r/gonewildstories/comments/aelba7/the_story_of_my_girlfriend_asking_me_to_fuck_her/) & [Part II](https://www.reddit.com/r/gonewildstories/comments/bxv843/part_ii_the_story_of_my_girlfriend_asking_me_to/)). In order to get the whole background of this construct I recommend to quickly go through these stories.
Basically I was asked by my girlfriend to do it, because her sister was very unhappy in her marriage and was desperately looking to be fucked again.
I know it sounds very strange and believe me the whole situation was completly crazy for me, but I can´t say that I had something to complain about.
After our second encounter the relationship to Emma (GF´s sister) got normal again to a non sexual relationship. We met regularly on family dinners or in a garden outside our home city that we shared with Emma´s family. Everything was just as it had been before and also my relationship with my girfriend Sarah had not taken any harm.
