Cause and Effect

Last winter I was staying with my girlfriend and her mother, my girlfriend is a nurse and was on night shift. It was a very cold night; the power went off due to heavy snowfall and a tree falling across the powerlines. With no power we had not heating in the place, that was the cause of me joining my girlfriend's mother in her bed. As a result, I got a hard-on and she felt it and let me fuck her. Which caused her to get pregnant to me, which was a complication as my girlfriend was already pregnant to me. Now married to my girlfriend and have a wonderful son with her and also a have a wonderful daughter with my mother-in-law. My wife didn't really care that I got her mother pregnant, as it was kept in the family. But I was told fuck another woman outside the family she'll cut my cock and balls off. So, I've been very faithful to my wife only fucking her and her mother. Perfect arrangement.
