Family connections

My family is very well off and have always been that, but they own no businesses. They buy property to sell to others sometimes, but prefer blue chip shares, Government bonds, short term investments and cash. They own private property where we live or go to for holidays and nothing much else. The family believes in investing, not actually producing anything and after university I'd to work. To learn how businesses operated and thus be able to invest better in the future. My father worked till his father passed away and he retired (42) to run the family finances. I will take his place when he passes away or retires. Using family connections, I got a great job at large national firm, the family had many dealings with over the years. Fast tracked to promote my career, I'd graduated top of my year at my Ivy league university. Bottom at sport and relationships, never been interested in sport and awkward with girls. Three years after joining the firm I was promoted and was given my own office and a personal assistant 23 years older than me. She had been a partner's assistant, but he (78) had passed away and his replacement already had an assistant. So, she was assigned to me, must have been quite a letdown for her. But one positive for her I was a lot younger at 30 and the odds were good she would get thru to retirement without another change. I'm quite comfortable around mature women so no awkwardness in our relationship. After a get to know each other period we were getting very well. I'd to travel as part my job and she always came with me, she soon worked out I was a sci-fi geek. Star Wars/Star Trek it didn't matter I would always want to attend any event on and she would tag along with me. I was away and a Sci-fi event was on in the same state and after the firm's business was completed. We attended the event, but we could only get one hotel room for the two nights we would there. It saved me money those as I'd to pay for the accommodation as it wasn't firm's business. Sharing room with 2 beds, wasn't a problem for her or me. We both enjoyed the event and had a lot of fun. On getting back to our room, we were mucking about for some reason I got hard-on. We hadn't been acting sexually towards each other and both fully dressed. But she saw it and offered to help get me off and it went from there. She was my first fuck and still is my only sexual partner. But we've a lot more sex since then and she is quite willing to provide sex to me and she also lives with me as well almost 2 years later.
