Timid Aunt

My aunt Trisha 49 is a very quiet woman and always has been, she married my father's younger brother Alexander. Alexander was a risk taker and a know it all and took one risk too many. I'm Jeffery 33 oldest of 3 and work for a large national firm. Then I got promoted and required a personal assistant and with the passing of Alexander, Trisha needed to find a job to get by. She had no children and quiet, she wasn't ideal as PA, but I knew she could handle the work. So, I employed her and to make everything easier for her and so, ad her move in with me. It took a month for her settle into the job but was good as I thought she would be straight away. A bit nervous around the others in the office. Anyway, I was happy with her work, she didn't cramp my nightlife either. But my relationship broke up and I was at a loose end and then went away on a business trip. With Trisha and we were delayed returning due airline cancelling our flights twice. Having to get another room closer to the airport as we had booked out before finding out our flight was cancelled. We got the last room at a motel close to the airport and it only had a double bed in it. I thought I could cope sharing with Trisha one night, she thought so too. But then then our next flight was cancelled also meaning another night sharing. Nothing we could do but accept it, we had dinner together and shared a bottle of wine. Anyway, we went back to our room and soon bored with TV. I was thinking of turning in and Trisha said was going to shower and I asked want me to wash your back. I was shocked when she said OKAY, so I followed her into the bathroom. Waiting for her to say she was joking. She didn't, so I washed her back, and she did mine. One thing led to another; we ended up fucking. We spent the following day fucking; I couldn't get enough sex from her. Finally getting back home and I had move into my bed with me and we've been sleeping together ever since. A colleague who works with me, Marian 30 I asked out on a date, she accepted. Marian likes Trisha a great deal also and she told she is bi-sexual and wanted to know if I would mind her seducing Trisha. She already knew Trisha was my aunt and I said go for it. Marian got Trisha into bed with her and then I joined them also. Trisha sleeps with me still and Marian has moved in with us and we regularly have threesomes.
