I moved aboard on the passing of my mother

As an only child never knew my father and completed college and started great career as a structural engineer. Also, very well off due to inheritance from grandparents and mother. At 30 I decided I should start a family and at 31 met my now wife. She like me is an only child and lived with her mother and they were just getting by. She as gorgeous woman and I would've married her without even waiting to get to know her better. But in their culture, there is the proper procedure to follow, quick marriages are looked down on. Believed to show loose morals as the bride must be pregnant. So, for family honor to be maintained you follow the procedure. First you announce your engagement, wait at least 6 months before announcing the wedding date. My now wife and her mother held their family honor above everything. I could fuck her before the wedding night but could stay overnight in a separate room. Their two-bedroom rental, one bedroom had a lock on the door which they used I slept in the other room. But I did get sex as the mother would join me and provide sex to me; she is also very attractive still. At the six months point we announced our wedding date. Unfortunately, due to it being a small village and only one church and only one week per week (Saturdays) you had to wait your turn. So, we picked the first available day and finally married 10 months and 2 weeks after our engagement. I realized the local priest was using the custom to his advantage, spreading out the weddings gave him a wedding each Saturday to attend, and I thought smart guy. Anyway, I soon had my wife pregnant, and we now have 2 children, and I also get sex still from my mother-in-law we all share the same bed even those we've a 4bedrom house. Perfect arrangement I believe.
