Odd Jobs

I'm living away from home attending university and to make extra money I do odd jobs and I'm pretty handy as I can plumbing and carpentry as I was taught my father and grandfather.
I'm not a great ladies man far from it but doing odd jobs I started making good money and able to put a bit aside. Then I was asked by one of my professors about doing some work for her. She about 55 and I was happy to earn more money and I went from mowing and other gardening to minor repairs to her home. Both plumbing and carpentry and while working installing a fitted wardrobe in her bedroom. She asked me was I willing to fuck her, that was like asking a hungry man if he wanted something to eat. Of course, I agreed, and she regularly has me fuck her after I've done mowing or gardening for her. I don't take money for the sex, not that I don't want to think of myself as male hooker. It's because I really enjoy the sex with her and it's for our mutual benefit. I've haven't fucked any other woman I do odd jobs for and quite happy with fucking my professor.
