My ex Mother in Law

I like to race cars, not professionally just an amateur. I'm Brian 32 divorced 2 children who live with mother Mary-Ann. Last year while racing around the track in a local derby I rolled my car, I hurt my back and nothing else. It wasn't all that serious except it would act up now and then. Just painful and restricted my movements when it was acting up, I was told to get a deep tissue massage when it played up. This seemed to ease it a lot and so when I felt it starting up I would get a massage, then in June masseur I was seeing moved away. There was only one other in our small town a masseuse named Rachel 52 widow my ex mother in law. She lived a block away from me and I tried to get by without any treatment but it became really painful. So I rang Rachel and made an appointment. Because of our relationship and the late request for treatment, she sgreed to see me out of hours. I arrived at her house at 8 pm on a Friday night, she looked over my treatment file I had with me. Then had strip down to my shorts and lay on the treatment table. Her fingers were very strong and she made me almost scream, but after I felt a lot better. Rachel told me that I should get regular treatment for a while to help repair the injury fully or it would keep recurring. So I asked when should I come again, everyday for a week she said should fix she replied. What time tomorrow I asked. Tomorrow I'm up at my cabin at the lake cleaning it up for some paying guest in a weeks time and Sunday as well, but if you come up there and give a hand cleaning it up I will do your treatment and won't charge you for any of it she replied. I agreed and met her at her cabin and while she done the inside I cleaned up outside,there wasn't all that much needed and I was finished in two hours and headed down the road to the diner and got some burgers and returned and had lunch with Rachel. She was almost finished the cleaning except for the bathroom, but she said she would do my treatment first. She had me lay on a bed in the main bedroom and she started on my back. As I laid on my front with my head to the side she was working from. I started to think what a sexy woman she was and I got a hard-on, then she wanted me to roll onto back so she could get me to bring my legs up and stretch my back muscles while doing that. I was a bit self conscious about my hard-on and as I was only in my shorts it might poke thru. But I did as I was told, at first my cock stayed inside my shorts and hoped she wouldn't see it. But as she pushed my legs up again and again, my cock poked thru the fly of my shorts still hard. She saw it and said nothing about it, then when she was finished she told me to remove my shorts. I looked at her at first but then removed my shorts. Telling to lay still she started pushing her fingers in around my abdomen and asking if had any pain. No I replied, still with my hard-on sticking out towards her. Then she asked me if I would like her to take care of my hard-on, I nodded okay and she started to stroke it. Then she undressed and mount me and she rode me until both of us had reached a climax. After which she said she couldn't let it go to waste as she hadn't had sex for a couple of years, I said I had enjoyed it as well. We stayed the night and from then on we have had sex at least once a week. My back is feeling a lot better now and I don't really need the treatment for it anymore. But there is this swelling that keeps coming up between my legs that she is still treating.
