Mature Co-workers

I had an affair with a mature woman 44 during my time at university and since then, I've had a sexual interest in mature women. So, after university I started work at my family-owned business, not at the bottom. But low in the management area, I was around family members mostly and got on with my work. After 18 months I was promoted and then I was given another promotion to an out of state part of the business. The manager had died of a heart-attack, and I was sent was interim manager until another manager could be found. There were only 12 staff working there and only 2 were men, 9 women worked in the making of the product and the other was the manager's assistant/secretary. None of the employees were under 47 and the younger 2 were the men working in the packing and shipping area. Of the women most were married and 2 were lesbians and only single was divorced and was my assistant/secretary 51 and she was the looker of the bunch. I wasn't sure how long I would there and decided to not socialize. But then as I was doing okay at the job, and they hadn't even advertised the job as of then. I was asked did I mind being there and I said I didn't mind the job or the town. So, I was given the job as manager until a vacancy back home came available for me, if I was happy to stay and I said I was. So, now I was the semi-permanent manager I could socialize and try my luck with my assistant, who I had taken a liking for. My chance came at the End of financial year 3-day meeting back home, I could've stay at home with the family but chose to stay the same hotel as my assistant. As I had her away from the office and in another state, I wanted to bed her. I used every excuse going to spend time with her. But didn't get close until the final dinner. Everybody enjoyed themselves and on getting to the hotel, I made a move on my assistant and got her into her bed and fucked her. Fucking her again in the morning, I was on a roll she was quite willing to sleep with and so we kept up a sexual relationship on our return. But due to an early retirement and a series of promotions back home, I was given a promotion and recalled home. Luckily for me the job came with an assistant, which I had to hire myself. I asked my assistant if she wanted the job, and she said No. But I made the suggestion she be given the manager's job as she was quite capable of doing it. She got the job and hired another assistant. On my return I had to hire an assistant, but first I decided to get a working knowledge of my new job. I was also checking the mature women working the company at the same time. None took my fancy as they say, but on a visit to the local library I met my old flame from university working as a librarian now 50. Having got divorced and she was as sexy as ever and we got talking. I found out she was only part time at the library and worked whatever she could get to get by. I slept with that night in a motel as she lived a boarding house, and I was living at home. I offered her the job as my assistant. She accepted and I got myself an apartment in a family owed building and my new assistant an apartment in the same building on the floor above mind with the fire escape as a secret connecting stairway. We slept together most nights and done all our travelling together, she also found a younger woman 26 for me to marrying as my family were pressing me to think about marriage. The young woman was her niece, and my assistant help bedded her niece and my assistant in a threesome. She got her niece to marry me as well and after our wedding we all started to live together. Now 6 years and 2 children later, we all still live and fuck together. My wife is happy having her aunt as my assistant as I won't stray. My wife prefers being a mother and we live next to my parents now, who are happy with their grandchildren and love their daughter-in-law. They don't think strange my assistant lives with us as she is my wife's aunt, I wonder what they would think if they found I was fucking my assistant and with my wife in bed with us while we did.
