Got a temporary job

At 24 living in one room no family I wanted to be near, working whatever I could get. I went for a job for just 5 day's work it was listed. But it paid better than most spot work, I was lucky I got a job one of the 6 hired. What's more it was 10hours shifts cleaning for the 5 days, so I would have some spare money for once. On the third day the owner (50) visited the building we were cleaning top to bottom. He'd bought the building, and it was filthy, you name it was on the floors, walls, ceilings and doors. We were given throwaway coveralls each day, pressure washing everything. That was after removing the rubbish, the walls, floors and ceilings were concrete, and it was being cleaned to be renovated. The owner looked at me for a time, I thought it was because I was the youngest. But said nothing, on the final day he returned and gave everyone a bonus for a job well done. But asked me to call him for a possible new job, I was willing to call him as he treated his workers a lot better than others did. He left and as we finished up, the supervisor told the contractor were starting on the building renovation the following Monday. I went home and decided to call the owner, and he asked me to meet him at his apartment the next morning at ten. I'm nothing special in looks or build (plain) and so sex wasn't what I thought about when I agreed to meet him. I arrived at the apartment building one of the best in the city, I got in without any hassles and on my way up to his apartment (Penthouse). I thought he must want a cleaner, I arrived and was invited in his penthouse was bigger than the building I's a room in. He started by asking me some basic questions, my health, relationships and any drug use. I said I was healthy but couldn't afford to see a doctor and had no relationship and usually steered clear of them too many hassles and didn't use drugs. He got straight to the point he was single no family left and wanted to start a family as quickly as he could. He added he would have me checked over by doctors and if I was healthy as I looked to be, he wanted me to give him children and I would be well rewarded. I always wanted to be a mother, and this looked like a great chance for me to become a mother. But I asked would I be able to help raise any child I carried. He was quiet for a short time then if you wish too, but he would be the parent in charge. So, I agreed, and he said he would've a contract drawn up. On the Monday following I meet him again and signed, contract was single one paper document, it stated I would be well looked after and that he final say over raising the children. I'd as he had asked me brought all my belongings, as I was live with him in the penthouse. After passing the Doctor checkup and was healthy. We started trying to make a baby, that was March 2017. I was soon pregnant confirmed by the doctor July 2017 and test showed the baby boy to be very healthy. Born in 2018 and pregnant again November 2019 and test showed a healthy baby girl. We were caught by the Covid lockdown, and our daughter was delivered healthy. As the contract only stated 2 children it was fulfilled, but the Covid meant we would have to stay together longer. But as the lockdown was coming to an end, I thought I should ask when he wanted me to move out. He said he didn't want me to move out and had thought I would be staying with him as I wanted involvement in raising our children. Also, I could have my own room if I so wanted, but he hoped I would stay in his bed still. I just nodded as I was totally comfortable with our living arrangements and in August 2021, I got pregnant again. We still live together, not married, but life partners you could say. Now we've 4 children 3 boys 1 girl and no plans to marry and everybody knows I'm the mother the children and his partner. I'm happy and also the children's legal guardian if something was to happen to him. He invested the money I got for having our first 2 children and it is doing very well, no more money paid as I have full access to his personal bank account. Anytime he travels we all go together, we're just like normal family just without the marriage certificate.
