Favor for favor

I've always been a bit of a mercenary; I do something for you do something for me. So, with that attitude, I started finding it hard to have long-term relationships. But where there a will there's a way, they say. So, I only had to find that way, well off career and money wise it soon occurred to me to use my success to get what I wanted. I soon found a perfect person that suited my needs you could say. A deserted wife (31) left with 2 small children, husband had left without any notice and disappeared. No money, no home shortly to top it off when I (36) came across her. Good looking woman, only downside for me was the 2 children, but they gave me extra leverage with her. First, I needed to get her albeit with the children isolated from people she knew, so she would've to rely on me only. First thing was somewhere for her and the children to live, I own 5 story apartment building, and I kept a vacant apartment for reasons I won't go into now. Not a 5-star building or even close, 2-star, I think. But it was better than the street, it was easier than I thought would be at first, she was even more desperate than I'd first thought she was. Not subtle in any way (never my strong point), it was better than the only option she had. Living on the streets and losing her children into state care. No really shock response to my offer, a short moment of thought then she agreed. She might have sold herself to strangers to survive, but my way she only had to sleep with me. The first couple of months, I think she was hoping her husband would reappear. He didn't, but I did treat her and her children fairly well. Then two things happened big career advancement with transfer and a large offer for my apartment building. Both accepted straight away, I decided to take her and the children with me as I was quite happy with our arrangement. In the new state I bought a 5bedroom house, no real reason other than it was closer to my new workplace than apartments were. My new office was away from the central business district closer to the airport which my employer's business in the state was mostly involved with. With the house and now living fulltime with my sexual servant and her children. She would look after my home as well as my sexual needs. I also got a dog from the animal refuge, no reason other than home security (Rottweiler). The children loved him straight away, she was a gentle giant and soon had bonded with the children. I thought he would live outside in the yard, but he lives inside and sleeps near the children at night. Only comes to my room during a thunderstorm along with the children. As time passed my bond with my lover grew stronger, we weren't so much master and servant, more of boyfriend girlfriend relationship. My mercenary attitude had disappeared as time had passed, with another promotion. I decided it was time to start a family of my own, first I adopted her children then married her. I thought I might have trouble adopting them, but it went thru quickly as their father had abandoned them. Quickly getting her pregnant and so hired a housekeeper, one benefit of having a live in housekeeper. No need to hire a babysitter when me and their mother go out. In the 6 years of our marriage, we'd 3 children and got an extra dog, another Rottweiler also a child loving dog. With two large dogs and children during a thunderstorm our bed couldn't take all the extra weight suddenly jumping on it. After losing two beds, we have just opted for mattresses stack on top each other now. No collapsed bed since. I'd found my soulmate without realizing it at the time.
