My Know all Neighbor's Daughter

My neighbor 57 thinks he know everything about everything, and he doesn't. But I'm not going to tell all his mistakes, it would take far too long for that. But he had one redeeming factor, his daughter a nice shy girl who is now my wife 25. I (28) realized quite early in our interactions to not challenge his statements. Thus, I became acceptable to him to date his only daughter and able to visit their home. I'd bought the house next door in late 2021 and took a fancy to his daughter straight away. My family was quite well off and using my trust fund I bought my house. I'd gotten a great job and the house I now own suited me best, close to my workplace and in a quiet area. The neighbor watched his daughter like a hawk and deterred every other man from approaching her. So, I befriend the father first and thus got to date his daughter, she an only child and had a sheltered upbringing home schooled. Her mother 50 is a very quiet woman also, it was several months before I heard actually speak. My neighbor is financially stable and will tell you about his views on anything and everything without you asking. After dating my now wife for 6 months I got her in my bed and realizing, it might cause problems for us with her father if he found out I promptly asked her to marry me. She wouldn't commit without her father approval and so I asked him, and he agreed to me marrying his daughter. I wanted a quick wedding, and we married 5 weeks later (September 2022), no reason to hurry she wasn't pregnant or anything. I wanted her with me all the time and it was quickest way to have her with me. Now I'd her in my bed every night and she was always willing to please me. One good thing from the being raised by him, in February 2023 the father had a heart attack and he survived but left weakened and at risk of more heart attacks and death unless he took it easy and followed the doctor's advice. Low and behold he is following the doctor's advice. He's on a transplant list and it's a case of when one turns up that matches him. So, he sleeps a great deal and as a result, I'm now fucking his wife as well as his daughter my wife. It started about 2 months (July) after his heart attack and release from hospital and my wife 8 months pregnant at the time I was feeling horny and made a pass at the mother while my wife was napping. She let me fuck her and that started my sexual relationship with mother. She comes over regularly to see her granddaughter when her husband is sleeping, he sleeps a great deal. My wife is okay with me fucking her mother and joins in threesomes with, all the sex is without precautions. No need with my mother-in-law and I want more children with my wife. My family have to visit us as we can't go away in case something happens with my wife's father. I'm quite happy with my marriage and how things have turned out.
