Expanding Family

I'm Alex 36 married to Heather 34 and have 5 children. I was dating Hanna 32 and after we broke up I started to date Heather (Hanna's sister) we married a year later. Long story short, I bought a large block of land with money from my late father's father James when I was 20, who left everything to as his only relative. As my father Mike had predeceased James, my mother Robyn 52 had remarried 3 years after Mike's death and had a daughter Casey 28 to her new husband Gerald who died in a car five years later. I was 3 when Mike died and I don't remember him all that much. I was 7 when Casey was born and 12 when Gerald died. So the land I then owned was a large block (20 acres) on the outskirts of the city then and due to expanding of the city. Started to become a drain on me due to it's rising value, I received several offers for it and a bidding war started and I got a very good price. I was able to buy an old style motel and had it fenced off to be my private home. As well as me, Heather, Robyn, Casey and then 3 children. Hanna and my mother in law Rebecca 50 divorced all moved in with us. I started to sleep with Hanna and Heather together and Hanna got pregnant and then also started to sleep with Casey and she got pregnant also. Heather was okay with me sleeping with Hanna and Casey and told me to keep it in the family, suggesting I sleep with Rebecca and Robyn as well. As Hanna and Casey were pregnant and Heather not wanting another child just then, said they are past having children and would keep it in the family. Rebecca was okay with sleeping with me and Robyn also came around after a friend of her from her work caught a nasty STD and decided that family was best. So I now have 5 children and may soon have more, all the Adults work, but there is always someone home with the children. Heather is thinking of another and so are Hanna and Casey.
