Dad's Ex Wife

My father Douglas 55 was married before he married my mother Rhonda 41. He didn't have any children with his first wife Elizabeth 47 and they were only married 6 years. I David 22 single and at university. Long story short Elizabeth never remarried or had any children, she and Douglas parted on good terms and she was welcome at our home, as far back as I can remember. I was at university in the same city as Elizabeth lives and due to a fire in my dorm I had to find somewhere to stay for at least a year. My mother Rhonda came to the city to help find a place for me to stay. While she was here she stayed with Elizabeth and it was hard to find something close enough to the university as there was a lot of students also looking for new places to stay and the rents went up a lot. Elizabeth is an artist and lawyer. She earns her living practicing law, but thinks she is an artist first. She has sold a lot of her work, but the legal work pays the bills. Elizabeth has a cottage 2 bedroom and a double garage in the back yard she uses as a art studio. After a week of searching with no luck, Elizabeth suggested I stay with her. Rhonda was happy to accept the offer, but didn't want Elizabeth being put out in anyway. Elizabeth said She would like the company and I could mow her yard for her, as she didn't like doing it herself. So I moved in and after several days Rhonda returned home. Elizabeth had another passion besides painting and that was cooking, but couldn't stand doing it all the time. She would cook up meals for a week on Sundays and wouldn't do anymore cooking until the next Sunday. On the Sunday I mowed the yard while she cooked and in the afternoon I studied and she painted in her studio. I'm play a lot of sport and keep fit, two weeks ago Elizabeth asked me to pose for a painting she was doing of an ancient Greek disc thrower. Just wearing a sheet over my shorts, but the sheet kept moving and showing the shorts. After several tries, Elizabeth asked If I would remove my shorts, so they wouldn't distract her thoughts processes. I removed them and sheet covered my private parts okay. After a couple of hours we took a break from the painting, we were having a cold drink and sitting talking. When I stood up the sheet caught on the corner of the chair I had been in and fell away as I walked away, leaving me totally naked. Elizabeth thought it was funny, as I tried to cover myself up. This gave her the idea of me posing nude for the painting. As she said The Greek preformed their sports mostly naked. I felt shy and then she said She would paint while naked to help relax. I wasn't sure, but agreed finally. While posing naked, I got another problem. My cock went hard as a rock and wouldn't go down, this also amused Elizabeth. She made some comments and I started to get ashamed. On seeing my discomfort, she stopped the comments and came over to me. She told me to lay on a padded bench and she would take care of my hard on for me. I done as instructed and she started to massage me all over. Before settling on my still hard cock. Which she started to stroke and then suck, it was amazing and I was soon getting close to coming and told her. She kept on sucking till I came in her mouth and she swallowed it all. Say waste not want not, then we went back to painting. A while later I got another hard on, mainly because I couldn't stop thinking about her blowjob. But this time, she decided I should blow my load inside and this she said Would help think more of the task at hand. So started my sexual relationship with Elizabeth, I sleep with her more or less every night. Except when my mother Rhonda visited last week, I found myself thinking of fucking her as well and Elizabeth noticed. Telling me that was okay as lot of boys think about fucking their mothers and that my father Douglas was having troubles having sex and Rhonda wasn't getting much at all and if was good. She Elizabeth would help me bed Rhonda next month during one of her regular visits.
