Dating

I tried dating and kept getting knocked back, the girl she had no interest in dating me. But now 4 years later we're married and have 2 children and another arriving soon. What cause the sudden change in my luck, her mother did. Her mother a widow and was working hard to keep her daughter and herself. Decided I was a good catch, so she started fucking me and also got her daughter to join us in threesomes. I was really enjoying the sex with the both of them and was told I should marry the daughter. So, I asked the daughter to marry me, and she accepted. She got pregnant before the wedding, but it didn't show at the wedding. I was 23 and she was 20 and her mother was 38 and also pregnant to me shortly after the wedding. I'm 27 now and have a good career and have my own home with my wife and my 3 children soon to be 4, the extra child is with my mother-in-law who I got pregnant around the time of my marriage to her daughter. Only us know the child is my mother-in-law's daughter, I've 2 sons with my wife and the new child is a girl according to the ultra-scans. Not even my parents know their first granddaughter is from my mother-in-law. Because that's what they were told and took as so.
